ABSTRACT

About 25% of cancers are initiated by infections, and therefore potentially preventable. Immunotherapyalready plays a significant role in cancer control: innate immunostimulators (eg imiquimod), passive immunotherapy (eg Herceptin) and active specific immunotherapy (eg Dendreon's prostate cancer therapeutic) are demonstrated effective, and many further therapies are in late stage clinical trial. Uniquely amongst human cancers, cancer of the cervix can be entirely attributable to an infectious agent. A subset of about 10 human papillomaviruses, termed high risk, are responsible, and two types (HPV16 and HPV18) account for more than 70% of cancers. Infection with high risk human papillomaviruses is extremely common, with up to 50% of women becoming infected during the first 5 years after commencing sexual intercourse. Up to 98% of these infections regress without intervention. Persistent infection conveys substantial risk of cervical cancer . Prevention of cervical cancer at present relies on screening programs. Future programs will likely be based on vaccines, to prevent HPV infection, now licenced in the USA, and Australasia. If administered prior to sexual activity, they will prevent up to 70% of cervical cancer in an unscreened population.

Report on the General Monthly Meeting​ by William Sewell​

The lecture on 1st November was delivered by Prof Ian Frazer, Australian of the Year for 2006, and Director of the Centre of Immunology and Cancer Research at the University of Queensland. He presented a fascinating overview covering not only his work on the development of the cervical cancer vaccine, but also the role of microbial infections in human cancers in general. The papillomavirus or wart virus is the cause of cervical cancer, which leads to about a quarter of a million deaths per year worldwide. In the early 1990's, Ian Frazer and colleagues developed a mechanism of producing non-infectious virus-like particles from papillomavirus. They were able to use these particles in a vaccine, which leads to long-lasting immunity against papillomavirus infection, and confers protection against cervical cancer. As a result of Ian Frazer's pioneering work, cervical vaccines will shortly become widely available. Cervical cancer is only one example of a cancer caused by a virus. About 25% of cancers worldwide are caused by viruses or bacteria. Ian Frazer highlighted the work of the Australian researchers Barry Marshall and Robin Warren, who discovered the link between Helicobacter pylori and stomach ulcers, which are a major cause of stomach cancer. The excellent lecture concluded with an overview of prospects for the future control of cancer.

Pandemics, Bird Flu and the Globalisation of Fear

Professor Peter Curson, Macquarie University

Date: Wednesday, 4th October, 2006
Time: 6:30 for 7:00 pm
Venue: Conference Room 1, Darlington Centre, City Road

ABSTRACT

Currently, the world is experiencing two defining events - a panzootic or global outbreak of bird flu, and a pandemic of human reaction and panic. H5N1 is spreading from country to country largely following the fly-paths of migratory birds. No one really expected the virus to race around the world so quickly. After remaining entrenched among wildlife in parts of Asia, suddenly the virus has moved further afield. No one really knows why, and there is still much we not understand about the infection. Like the SARS experience, however, the animal infection is at danger in being swamped by the outpouring of human reaction, panic and hysteria. The world press is having a field day, the word pandemic is on everyone's lips, and governments and individuals have been stockpiling antivirals. Pandemic planning has become an industry, and wherever you look, there are dire predictions of millions of deaths and widespread social and economic disruption. The line between responsible precautionary behaviour and alarmist fear mongering has become increasingly blurred. There are two fundamental issues involved. One is the threat to animal life and the related implications for those whose livelihood depends on such animals; the other is the potential threat to humans. They are not the same thing and need to be separated. This talk considers human reaction and behaviour when confronted by pandemic crises.

Date: ?? September 2006

Flushed with success, the Council of the Royal Society decided it was time for a bit of a heels-up - or rather heads-down - to look at treasured items from our wonderful collection. The occasion? A soirée at the Nicholson Museum in The University of Sydney to celebrate the achievements of the previous twelve months.

In that time, the Council managed to win two grants. The first, a State Government grant of $30,000 to be used for the publication of the journal over the next three years, was the work of past president Karina Kelly and her team. The second was $5,500 through one of the Federal Government's Community Heritage Grants organized by the National Library in Canberra.

It was through this grant that our consultant historians, Dr David Branagan and Dr Peter Tyler, assessed the Society's collection of books, journals, maps, drawings, painting, photographs, lantern-slides and medals to be highly significant both historically and scientifically. Selected items were displayed in the facilities offered by the Nicholson Museum. Staff and guests donned cotton gloves to leaf through some of the precious books, which included works by the American archaeologist and naturalist Charles C. Abbott, and Opuscula, one of the most significant books in the Society's collection, written in Latin by Georg Bauer, better known by his Latin name, Georgius Agricola (1494-1555). He is considered the founder of geology as a discipline. Another book, Cyrillus in Johannem et Leviticum una cum thesauro eiusdem was published in 1508. It is the only one held in Australia. There was also the first volume of Curtis' Botanical Magazine, beautifully illustrated by the artist Sydenham S. Edwards and published 1787. The Society holds the complete set (Volumes 1-14) and many other volumes of the Botanical Magazine by various other publishers.

Also on display were Lawrence Hargrave's aeronautical and other papers, together with some of the drawings and lantern-slides of his first flying machine, and a very rare edition of J.D. Dana's Geology, written when he accompanied W.B. Clarke around the Sydney Basin. Hand-written letters from Society member Charles Darwin and Louis Pasteur were a great attraction. Many of the medals on display were from Clarke's collection. These are kept in the care of the Mitchell Library together with some 20 boxes of books and other items belonging to the Royal Society. These are to be the target of our next round of assessment and listing.

Undeniably the society is the custodian of a remarkably important collection. It is imperative that we take every step to preserve it and to make it available to all.

Guests at the soirée included the university's Vice Chancellor, Professor Gavin Brown and his wife, Diane, the former Vice Chancellor of Macquarie University, Professor Di Yerbury, acclaimed photographer-astronomer, Professor David Malin, Scientia Professor Eugenie Lumbers from the University of New South Wales, the ABC's Robyn Science Williams and many others.

The soirée was not without its formalities. President, Professor Jak Kelly set the scene, explaining the grounds for the celebration and thanking Professor Brown for so generously arranging premises for the Royal Society. He also thanked Professor Di Yerbury for her help in housing the Society and its collection at Macquarie University for some years. Councillor John Hardie spoke about the work that had been done on the collection through the funding, and outlined some of the recommendations from Peter Tyler's report. These included the urgent need to house the collection suitably so that it could be properly conserved and made available to researchers and the public alike. He also suggested that the Society should initiate a long-term project to "return Science House to Science". He reminded guests that Science House won the first Sulman Medal for Architecture for its architects, Peddle, Thorpe and Walker, in 1932.

Society member and former president, David Branagan, who was also one of the assessors, described some of the "treasures" he had examined and the insight they give to the development of our intellectual and scientific history from Colonial times. Professor Gavin Brown thanked the Royal Society for inviting him and his wife and congratulated the Society on its achievements in recent years.

It was after the formalities that guests were free to peruse the displays to the sounds of restful chamber music from the trio, Sound of Melody, adding to the already splendid atmosphere of the museum itself. David Branagan and members of the Council's grant committee were on hand to assist with enquiries and to point out items of special interest.

The evening finished on a high note when Society received an unexpected accolade from the Senior Curator of the Nicholson Museum, Michael Turner, who said that he had really enjoyed having so erudite and enthusiastic a group of people at the museum.

The Frontier of Measurement: Leading-Edge Standards for Length and Time

Dr Bruce Warrington, Head of the Time and Frequency Group at the National Measurement Institute in Lindfield, Sydney

Date: Wednesday, 6th September, 2006
Time: 6:30 for 7:00 pm
Venue: Conference Room 1, Darlington Centre, City Road

ABSTRACT

Metrology, the science of measurement, is a dynamic field of research. Advances in understanding and technology extend our ability to measure to ever higher levels of precision, and this capability in turn stimulates new applications. The ability to precisely measure time, or its counterpart frequency, underpins modern technology. Frequency is the physical quantity we can measure most accurately, and implements standards for many other physical units, including the metre and the volt. The SI definition of the second presently has an accuracy approaching 1 part in 10¹² for commercial standards, and better than 1 part in 10¹⁵ for research-grade standards. The relatively recent development of optical "frequency combs" will further extend this frontier of measurement. These new capabilities at unprecedented levels of precision have the potential to revolutionise our understanding of the physical world and lead to applications previously undreamt of.

​BIOGRAPHICAL NOTES​

Dr Bruce Warrington is the head of the Time and Frequency group at the National Measurement Institute in Lindfield, Sydney. A graduate of the University of Otago, he has a DPhil from Oxford on atomic and laser spectroscopy and fundamental physics. After postdoctoral appointments in Oxford and at the University of Washington in Seattle, he joined the CSIRO National Measurement Laboratory in 1998. He has led the time and frequency area since the formation of the National Measurement Institute in July 2004.

The Overshadowed Centenary - the Discovery of the Pinch Effect in 1905

A/Prof. Brian James, School of Physics, Sydney University.

Date: Wednesday, 2nd August, 2006
Time: 6:30 for 7:00 pm
Venue: Conference Room 1, Darlington Centre, City Road

ABSTRACT

Attempts to harness the enormous nuclear energy available from fusing hydrogen into helium have gone on for half a century. To achieve fusion the hydrogen has to be massively compressed for a sufficient length of time for the reaction to occur. Most of the efforts have been concentrated on confining and compressing a gas discharge in hydrogen. Pulsing a massive current through such a discharge produces a magnetic field that "pinches" or constricts the discharge sufficiently to produce fusion. The problem is to engineer such a fusion reactor so that more power comes out than is required to run it. A new multi billion dollar machine, to be built in the south of France, is hoped to achieve this aim at last.

It is a little known fact that the theory of the Pinch Effect was first published in our journal over a 100 years ago, "Note on a Hollow Lightning Conductor Crushed by the Discharge" published in the Journal and Proceedings of the Royal Society of NSW 39 (1905) 131-8.

Come and hear how an investigation of a crushed hollow rod from a lightning conductor at a kerosene refinery in Hartley Vale in NSW led in 1905 to the first description of the Pinch Effect by James Pollock, Professor of Physics, University of Sydney and Henry Barraclough, Lecturer in Mechanical Engineering, University of Sydney. With a few diversions along the way, this talk will look at the investigation of the crushed conductor which lead to explaining the Pinch Effect and its subsequent relation to the history and current developments in nuclear fusion research.

Report on the General Monthly Meeting​ by Jak Kelly​

We are indebted to Brian James for bringing to our attention a seminal paper "Note on a Hollow Lightning Conductor Crushed by the Discharge" published in the Journal and Proceedings of the Royal Society of NSW 39 (1905) 131-8. It was by James Pollock, Physics and Henry Barraclough, Mechanical Engineering, both of the University of Sydney. In 1905 a copper tube from a lightning conductor at a kerosene refinery in Hartley Vale in NSW was mysteriously crushed by a lightning strike. Their paper solved the mystery as due to the crushing effect of the powerful magnetic field generated by the massive current through the pipe. This "pinch" effect has over the last century been of importance in a number of fields, particularly the technology for generating power from hydrogen fusion. Starting from Hartley Vale we were taken on a lucid and interesting tour of the basic physics involved and on to current fusion research and its historical development.

Asian Honey Bees: Biology, Conservation and Human Interactions

A/Prof. Ben Oldroyd, School of Biological Sciences, Sydney University.

Date: Wednesday, 5th July 2006
Time: 6:30 for 7:00 pm
Venue: Conference Room 1, Darlington Centre, City Road

ABSTRACT

The familiar European hive bee, Apis mellifera, has long dominated honey bee research. But in the last 15 years, teams in China, Japan, Malaysia, and Thailand began to shift focus to the indigenous Asian honey bees. Benjamin Oldroyd, well known for his work on the genetics and evolution of worker sterility, has teamed with Siriwat Wongsiri, a pioneer of the study of bees in Thailand, to produce a new book, recently published by Harvard University Press, synthesizing the rapidly expanding Asian honey bee literature. The talk will provide a synopsis of the book including evolution and speciation, division of labour, communication, and nest defence.

Oldroyd will underscore the pressures colonies face from pathogens, parasites, and predators – including man – and detail the long and amazing history of the honey hunt. He will also discuss directions for conservation efforts to protect these keystone species of Asia's tropical forests.

He previously worked in the Victorian Department of Agriculture, the bee laboratory of USDA at Baton Rouge and La Trobe University. He has published over 100 papers on bee genetics, evolution and behaviour.

Report on the General Monthly Meeting​ by Jak Kelly​

The familiar European hive bee, Apis mellifera, has long dominated honey bee research. Our speaker described the recent change in emphasis by researches in China, Japan, Malaysia, and Thailand away from the European and towards the indigenous Asian honey bees. Professor Oldroyd and Siriwat Wongsiri, a pioneer of the study of bees in Thailand, have recently published a book [Harvard University Press] which synthesizes the rapidly expanding Asian honey bee literature. This lecture was based on material from the book and dealt with the Asian beeâs evolution and speciation, division of labour, communication, and nest defence against pathogens, parasites, and predators - including man. Honey has always been a prized food for both animals and man and there were fascinating pictures and descriptions of how local people have developed methods of harvesting the honey. As with an increasing number of natural resources, some of the keystone bee species of Asia's tropical forests are threatened. Some of the conservation efforts to protect these bees were described. A fascinating lecture on a subject which few of us knew much about. Not a good research topic for people allergic to bee stings.

Global Evolution of Ocean Basins

Time: 6:30 for 7:00 pm
Venue: Conference Room 1, Darlington Centre, City Road
(City Road, side entrance to the Forum Restaurant)

ABSTRACT

The large-scale patterns of mantle convection are mainly dependent on the history of subduction. Hence some of the primary constraints on subduction models are given by the location of subduction zones through time, and of the convergence vectors and age of subducted lithosphere. This requires the complete reconstruction of ocean floor through time, including the main ocean basins, back-arc basins, and now subducted ocean crust, and tying these kinematic models to geodynamic simulations. We reconstruct paleo-oceans by creating "synthetic plates", the locations and geometry of which is established on the basis of preserved ocean crust (magnetic lineations and fracture zones), geological data, paleogeography, and the rules of plate tectonics. We have created a set of global oceanic paleo-isochrons and paleo-oceanic age grids, providing the first complete global set of paleo-basement depth maps, including now subducted ocean floor, for the last 130 million years based on a depth-age relationship. We show that the mid-Cretaceous sealevel highstand was primarily caused by two main factors: (1) the "supercontinent breakup effect", which resulted in the creation of the mid-Atlantic and Indian Ocean ridges at the expense of subducting old ocean floor in the Tethys and (2) by a changing age-area distribution of Pacific ocean floor, resulting from the subduction of the Pacific-Izanagi, Pacific-Phoenix and Pacific-Farallon ridges. These grids provide model constraints for subduction dynamics and represent a framework for back tracking biogeographic and sediment data from ocean drilling and for constraining the opening/closing of oceanic gateways for paleooceanographic models.

BIOGRAPHICAL NOTES

Dietmar Müller graduated from the University of Kiel in 1986. His PhD, in 1993, is from the Scripps Institution of Oceanography. His work is focussed on global and regional Earth system problems by linking onshore and offshore observations based on geophysical/geological data and kinematic/dynamic process modelling, exploring the possibilities of the emerging area of e-geoscience. He was elected a Fellow of the American Geophysical Union in 2006.

Report on the General Monthly Meeting​ by Jak Kelly​

No brief review such as this can do justice to Professor Müller's impressive computer simulations of the movement of the continents and particularly the changes in the floor of the oceans over the last 130 million years. Accustomed as we are to computer animation, the fact that the motions of the Earth's crust depicted here are based on the best current geological information puts them in another league. We see India racing north [geologically speaking] pushed from behind and dragged by subduction forced to eventually pile up the Himalayas with attendant ocean floor developments. The forces are such that, in spite of these massive mountains, India is still moving north. Australia, moving north at about the rate that fingernails grow, has lagged behind. It will be some time before we crash into Asia and start our own serious mountain building. Most of us knew about this in general but what was new was the detailed information on what has happened over time to our oceans, which have been almost completely reconstructed. Using the rules of plate techtonics and geological data from preserved ocean crust, the paleo-oceans were constructed and their development over time followed. In the Tethys, old ocean floor has been subducted to form the mid-Atlantic and the Indian Ocean ridges. In the Pacific, the Pacific-Izanagi, Pacific-Phoenix and Pacific-Farallon ridges have been subducted to produce the present ocean floor. The impressive computer simulations which encapsulate all this information convey the changes more memorably than could have been achieved by any other method.

The Genetics Behind our Drinking Water Turning Toxic

Professor Brett Neilan, School of Biotechnology and Biomolecular Sciences, University of NSW

Date: Wednesday, 3rd May, 2006
Time: 6:30 for 7:00 pm
Venue: Conference Room 1, Darlington Centre, City Road

BIOGRAPHICAL NOTES

Professor Brett Neilan was a member of the team who won the Royal Societies of Australia 2004 Eureka Prize for Interdisciplinary Research.

Report on the General Monthly Meeting​ by Eveline Baker ​

Professor Brett Neilan commenced his lecture with the statement that, in a presentation to members of our Society 15 years ago, blue green algae were a problem that may have a cure. He believes that this is the case in more ways than one. Improving water quality is a process not only in engineering but also in discovery of natural products. Knowledge of the toxins could lead to knowledge of anti-cancer agents. The environment dictates evolution and adaptation. Survival is achieved at the molecular level. The diversity of life on earth and all things biological derives from molecular diversity. Vast stromatolite reefs have survived for about 2.5 G-years, before the origin of eukaryotic life. Found in selected coastal areas of the world, including Western Australia, these are sedimentary, calcium carbonate based formations, fossils of blue-green algae, not all of which relied on photosynthesis. Interestingly, bluegreen algae have a mechanism for surviving in high salt media and even produce calcium carbonate in the laboratory. Secondary ion mass spectrometric data indicate that some of the larger stromatolites may have grown about 10,000 years ago. The Antarctic has melt-water hyper-saline ponds in which "mermaid's hair" proliferates. Toxins have been found in these and similar slime layers. Interestingly, some Africans eat blue-green algae as food. In other areas of the world liver cancer is prevalent in those who drink 'green' water. It is a worthy question to ask why some people survive and others become ill and die. Pathogenicity has been found to be determined by the DNA cluster, not the organism. The level of light determines which promoter is used to transcribe the toxin genes. Toxins have been found to become harmful to animal and human life when they move outside of the cell. The chemical structure of several of these neuro-toxins has recently been determined. It is interesting to observe that the toxin molecules are relatively small and similar in structure to some of the currently known natural and synthetic drugs that influence neural activity.

Cold Fusion, the Alchemist's Dream?

Annual General Meeting & Presidential Address by Professor Jak Kelly, President of the Society

Date: Wednesday, 5th April, 2006
Time: 6.30 for 7:00 pm
Venue: Conference Room 1, Darlington Centre, City Road

ABSTRACT

A brief history of cold fusion and where it fits into conventional physics will be given, leading up to the most recent results. Cold fusion remains a controversial subject. There are more theories than theoreticians working in the field, none of which are universally accepted. The original objective of the field was the release of thermal energy by fusing hydrogen isotopes into helium with simple apparatus and without producing the dangerous amounts of radiation normally associated with conventional fusion and fission.

Many laboratories now routinely produce excess heat from cells developed from the original Fleishman and Pons cells at the University of Utah. One of the most interesting development is low-energy nuclear reactions (LENR) in which elements are transmuted into other elements, the alchemist's dream. A potential application of LENR is the conversion of radioactive waste into nonradioactive isotopes.

Report on the General Monthly Meeting

"Cold fusion: the alchemist's dream?" was the title of the Presidential Address, following the AGM. Professor Kelly gave a brief history of the developments in cold fusion since the Pons and Fleishman announcement in Utah in 1989. Many remain sceptical of the existence of such a fusion reaction, because of initial difficulties in reproducing their excess heat results and prolonged attacks on the field in the media and by the hot fusion community. Successful electrochemical anomalous heat experiments have however been carried out in many laboratories in numerous countries. Similar results have been obtained using different methods, such as diffusing deuterium through thin films of palladium and other metals. Tritium has been detected in many such experiments, clear evidence of a nuclear transition. There is still no universally accepted theory but there is now general agreement that CF is a near surface phenomenon and the lack of the expected significant amounts of radiation is probably associated with slow resonance reactions. A more recent and surprising development is the detection of numerous other elements in the metal films used. They cannot be explained as impurities because their distribution is much different from that found in control experiments and in addition, some isotopes have been detected which differ from those found in the normal element. These low-energy nuclear reactions are under intense study in a number of laboratories and there is a trend towards calling the field LENR rather than the unfortunate name cold fusion, to which so much emotion is attached. There is, as yet, little promise of turning out significant amounts of gold, so the alchemist's dream remains a dream; however a more significant potential application of LENR is to the conversion of radioactive waste into more stable non radioactive elements. This paper will be published in the next issue of our Journal.

Can the Physicists' Description of Reality Be Considered
Complete?

Nobel Laureate Professor Brian Josephson, Cambridge University

Date: Friday, 17th March, 2006
Time: 6:30 pm
Venue: Eastern Avenue Lecture Theatre, Sydney University

The Pollock Lecture is jointly organised about every three years by the Royal Society of NSW and the University of Sydney. It is given in memory of James Arthur Pollock who was Professor of Physics at Sydney University 1999-1922. This year the lecture was in conjunction with the Australian Institute of Physics and was delivered by the Nobel Prize winning physicist Professor Brian Josephson of Cambridge University. It was to have been held in the Eastern Avenue Lecture Theatre at Sydney University but the audience of over 400 so far exceeded expectations that the venue was shifted to the larger Auditorium A group of about 30 went on to dinner with Professor Brian Josephson and his wife Carol.

ABSTRACT

In his book Atomic Physics and Human Knowledge, Niels Bohr argued that because of the uncertainty principle quantum methodology might not be applicable to the study of the ultimate details of life. Delbruck disagreed, claiming that biosystems are robust to quantum disturbances, an assertion that is only partially valid rendering Bohr's argument still significant, even though normally ignored. The methods of the quantum physicist and of the biological sciences can be seen to involve two alternative approaches to the understanding of nature that can usefully complement each other, neither on its own containing the full story. That full story, taking into account the biological/cognitive/semiotic perspective, may involve anomalies that are incomprehensible from the standard physicist's point of view. It provides a fascinating challenge for the future of physics.

​BIOGRAPHICAL NOTES​

Professor Brian Josephson FRS is Professor of Physics at the University of Cambridge. While a graduate student he predicted that currents could tunnel with no resistance through an insulating barrier between two superconductors, for which prediction he was awarded the Nobel Prize in Physics in 1973. Since then he has been mainly concerned with the question of the logic of brain functioning, as well as being interested in a number of topics that have become the subject of "pathological disbelief". He was one of the instigators of the web site http://www.archivefreedom.org, which publicises cases of the bureaucratic censorship of research that does not fit in with conventional thinking.

A Cradle to Grave Concept for Australia's Uranium

The February meeting of the Royal Society of NSW was the annual meeting of the Four Societies, The Royal Society of New South Wales, The Australian Institute of Energy, Australian Nuclear Association and Engineers Australia (NUC Engineering Panel).

Speaker: Dr Clarence Hardy, Secretary ANA, Vice-President Pacific Nuclear Council
Date: Wednesday, 22nd February, 2006

BIOGRAPHY

Dr Clarence Hardy retired in 1991 after a 35-year career in nuclear science and technology in senior positions in the UK, USA and Australia. He worked for 20 years as a Division Chief and Chief Scientist at the Lucas Heights Research Laboratories in Sydney and his history of the Australian Atomic Energy Commission was published in 1999.

ABSTRACT

Dr Hardy will discuss the advantages of an Australian [involving international partners] integrated nuclear fuel complex for the world's nuclear power programs, for Australia and international non-proliferation. It would take Australian uranium right through to the production of nuclear reactor fuel elements which would be leased to nuclear power programs, with the spent fuel returned to Australia. After reprocessing, the unused uranium and plutonium would be reprocessed into MOX fuel for reuse. The high level waste, in Synrock, would be stored in Australia. This international initiative would place Australia at the leading edge of the nuclear industry, earn enormous export revenue and be a major contribution to non-proliferation. The scale of the enterprise would make it the 21st century equivalent of the Snowy Mountains scheme.

Report on the Four Societies Meeting​ by Jak Kelly​

Dr Hardy's proposal is that as we have 37% of the worlds useful deposits and 22% of the world's uranium production we should do more value adding instead of just exporting the raw material as we have done and still do, with many of our materials. The full project would cost some seventeen billion dollars but although this seems prohibitively expensive, recent mining projects have involved comparable expense. International involvement would be essential, not only financially, but to ensure continued viability for any project fraught with such emotional, political and military implications as the enrichment of uranium.

A large part of the world's enrichment capacity is still based on the original diffusion methods. These plants, half a century old, are reaching the end of their life in Russia, France and America, which combined with the proposed building of many new power reactors, will lead to a serious shortage of processed fuel in the next few years. The project involves enriching the Uranium, making it into fuel elements and leasing them to reactor operators. The depleted elements would then be returned to Australia for further processing, to extract remaining fissionable materials for reuse, and the residual radioactive waste, encased in Synrock, would be buried in a geologically stable site in Australia. The considerable heat generated by radioactive material could be used to power a desalination plant. Modern small centrifuge separation technology is now mature and would be available for this project. The project could be developed in stages with the first stage, the enrichment of uranium hexafluoride, starting to pay for itself in three yeas.

Aside from the considerable problem of public resistance to importing radioactive waste, several state and federal laws against it would have to be repealed. The major political parties would have to agree, to avoid a change of government sinking the long term project, as has happened in the past. The International Atomic Energy Authority would favour such an internationally run project in a politically and geologically stable country like Australia. The hazards of shipping uranium, fuel rods, and radioactive waste between many distant sites, which occurs at present, would be greatly reduced as would the opportunities for theft of fissile material. Such a high-tech industry would also provide employment and development for Australian science and engineering in a way that being an efficient quarry does not.
