Expanding interest in laser enrichment

General Electric and Hitachi have now been joined by Cameco to develop and deploy Australian laser enrichment technology. Cameco has invested US$123.8 million (AU$129.8) to become the minority partner with a 24% stake in the joint venture. GE will maintain a 51% share and Hitachi 25%.

It's always interesting to hear of Australian innovative success, but in general news such as this is disappointing for me personally. I hope Silex is bringing home some well deserved royalties for their efforts on the technology [judging by the below stock trend, this appears to be the case]. However, I still consider it [another] lost opportunity via the export of innovative technology as well as [most likely] a few key human resources.


This phenomenon is not unique to the nuclear fuel cycle either. Australian solar technology continues to suffer a similar plight. Considering the global energy [r]evolution unfolding before us - I do not believe it wise to allow similar opportunities to slide so easily from our grasp.

Players and prophets - where are coal and nuclear headed in Australia

Over the past weeks there has been much ado about the future of carbon capture/clear coal in Australia; recently a world nuclear strategist made predictions about Australia's nuclear future; and despite domestic and international efforts to prevent it, coal exports are set for a massive increase.

First, some thoughts on the many recent articles about domestic carbon capture technologies and projects here and abroad. Please don't get me wrong. I hope they succeed; hope they bring much deserved accolades and even some profits to the Aussie researchers labouring on the technologies; hope they permit the continuation of massive profits for the Australian coal industry and in particular those relying on it for their daily sustenance; hope they result in massive worldwide carbon emission reductions while facilitating improved living conditions for many developing countries around the world.

But - to me - actions speak volumes over words. When I consider ongoing claims of economic ruin and pleas for exemptions or some other type of mitigating action, I realise my hope is not manifested in the general economic confidence of the Australian energy industry. The entire point of an emissions trading scheme is to put financial pressures on these facilities to either clean up their act or shut down.

With respect to political policy. I note the public promotion of carbon capture/clean coal by many public officials. However, I don't hear anyone proposing a moratorium on new fossil stations that do not bring carbon capture technologies online with them, as suggested by NASA chief, James Hansen, in a recent letter to Kevin Rudd.

So, let's focus on the problem. Provided one accepts the science that strongly [and getting stronger as time passes] suggests human generated emissions, primarily from the burning of fossil fuels, must be dramatically cut; considerable action is required. We must also achieve significant progress related to the contributing challenges of optimising the removal of greenhouse gasses in the atmosphere today as well as developing and implementing climate change mitigation strategies on an international scale, put particularly in Australia.

So what are we doing to address these issues? We're building some wind farms. We're building some solar plants and smaller scale household hot water heaters. We're looking into geothermal power and as discussed above we are working to develop carbon capture/clean coal. But there are also new fossil stations on the books. With all these plans our emissions, in the best case scenario, will not decrease by any percentage from 1990 levels, but will remain flat at 108% of 1990 levels to 2020.

The intentions seem noble and the efforts considerable. But they are simply not enough to address the problem.

Can nuclear play a role? I think so. Should nuclear play a role? I think so. However, looking at the facts [unfortunately the most relevant of which are subjective/political] - I must concede the opinion of Steve Kidd, Head of Strategy and Research at the World Nuclear Association. Considering all the constraints, Kidd notes a 'less promising' future for nuclear in the near term under Labor, but hedges, saying the true policies remain to be seen.

Kidd does see a favourable environment for expanded uranium mining [OK, that's an easy one], but also conversion and enrichment in Australia. One route suggested in the article could be for an Australian joint venture employing ANSTO developed laser enrichment technology with General Electric and an Australian company or companies. This makes sense on many levels, not least significant of which will be the dramatic reduction in handling and transportation energy inputs to the fuel supply chain through conversion and enrichment facilities located relatively close to the uranium source.

Finally, one last look at Australian coal. Where is it headed? The below line from the Courier Mail says it all.

RIO Tinto Coal Australia believes it can double its Queensland coal production to 40 million tonnes a year within seven years, thanks to booming demand and planned new rail and port capacity.
I doubt this will solve any problems. Again, looking at actions [or, in this case proposed actions] it seems clear to me; we are not doing enough to address the relevant technical issues.

Germany's nuclear power options

In Germany - long renowned as the stalwart, nuclear phase-out poster country - the winds appear to be changing.

Not only is EOn CEO Wulf Bernotat calling the phase-out plan incomprehensible as reported here by World Nuclear News, but Germany has also proposed a multi-national enrichment facility.

Many nuclear bloggers have picked up on [what I think was initially NEI’s theme] ‘another pro-nuclear blogger’. I’ve often cited ‘environmental conversions’. What’s this now, another nation for nuclear power? Consider that in the past year or maybe just a bit more, major shifts in nuclear polity have occurred in Sweden, the UK, the USA and even in Australia [elimination of 3 mines]. And, there are many, many others.

Looks like the world – or at least a significant part of it – is getting serious about no/low emissions technologies in the context of global energy security challenges.

APEC - and so it begins

It's all happening now.

The announcements have come pretty much as anticipated.

The Age
The Sydney Morning Herald [Small business section in a tourism article? A bit buried maybe?]

Australia is moving to join both initiatives [yes, there are two things to discuss here].

First comes the Generation IV International Forum [Gen-IV]. This partnership has existed for some time now. Originating in the west, slightly behind the Russian lead INPRO initiative onging within the IAEA, Gen-IV is principally technically oriented. The work involves applied science and engineering projects to develop advanced reactor designs with vastly improved fuel cycles, lower waste generation, still further improved safety and security features, shorter build times and lower cost. The participation in Gen-IV and INPRO involves considerable overlap and the two are working well together in a fairly complimentary way. INPRO has developed assessment criteria for potential Gen-IV designs for example that could be applied to the concepts currently being further developed within Gen-IV.

I imagine ANSTO will be the principal point of contact for this work - but OPAL was not designed for some of the most exciting of this research [testing of advanced fuel designs etc.] and may require some modifications to fully support the needs of the various programmes. This is why, for example the USA has NIST, ORNL and others for the heavy duty neutron scattering / materials science as well as the ATR - which exists principally to test advanced fuel and core materials. The commencement of relevant OPAL modifications will please me immensely. How exciting will it be that the world's newest research reactor initiates such a significant modification? Evidence of rapidly changing [and expanding] nuclear interest here in Australia and abroad!

Next is the much less technically exciting GNEP, which I have recently posted about here and here. I say less technical because the advanced plants [burner reactors] will most likely come out of the Gen-IV programme. Unless GNEP grows to eventually swallow Gen-IV as it very well may do. GNEP is now at least the third iteration of 'bigger and better' nuclear initiatives involving the USA. Previously initiated and ongoing in parallel with the aforementioned Gen-IV, there are the Advanced Fuel Cycle Initiative, Nuclear Power 2010, the nuclear hydrogen initiative and probably a programme or two more.

My guess is that GNEP and Gen-IV are being bundled to focus on the research activities that come with Gen-IV and the US can put another run on the board as far as GNEP participation is concerned [i.e. about as much of a win-win that each could expect from such an announcement].

All I can add to the previous GNEP posts is that, as reported above, we are 'reserving the right to enrich' and proceeding with the process to join the partnership on the condition that Australia accept no waste from foreign states. Also, the 'meeting in Vienna' that is mentioned in some of the media reports will occur around [immediately prior to, I think] the IAEA General Conference. Within the international nuclear world, this is the time of the year for BIG announcements - so let's all brace ourselves and hope for the best.

Global Nuclear Energy Partnership (GNEP)

What does this mean for Australia, the United States, and other developing and developed ‘partners’? That’s a tough question to address in one post – but I’m getting a bit busy and new posts may be scarce for a while. So I’ll do my best.

During the recent 48th Annual Meeting of the Institute of Nuclear Materials Management conference in Tucson Arizona, there was considerable attention given to the GNEP. Both the first speaker in the opening plenary [Dr. Paul Lisowski, Deputy Assistant Secretary for Fuel Cycle Management, Office of Nuclear Energy, US Dept. of Energy [DoE]] as well as the last speaker of the final plenary [Adam Scheinman, Assistant Deputy Administrator for Non-proliferation and International Security, US DoE, National Nuclear Security Administration] emphasised the role of GNEP including progress with countries including Russia, China, Japan, France, etc. Additionally, three technical sessions were devoted to GNEP. These included 6 panels and about 20 individual presentations from both government and industry.

As one looks beyond the marketing of GNEP it becomes obvious that the programme faces some significant challenges [beyond the funding problems being imposed by the US congress]. Few people have much to say about the strategic goals of the programme: to promote global energy security and reduce dependence on climate killing fossil fuels through the dramatic expansion of no/low emission nuclear technology. Furthermore that nuclear technology will be expanded in a way that minimises proliferation risk and drastically reduces the long-term repository burden from high level waste.

However, with respect to tactical implementation, the waters begin to muddy. My understanding is:

1. Non-proliferation goals of the US [as well as just about any other country in charge of its mental faculties] would be achieved through the voluntary agreement of ‘recipient’ or ‘partner’ countries to forego nuclear fuel enrichment based on long-term fuel supply assurances from a collective group of fuel supplier [aka fuel cycle] states [mostly those who already have nuclear weapon capabilities, with possibly a few others].

2. Fuel supplier states would become involved in fuel reprocessing to generate fuel for fast burner reactors. These reactors would digest the minor actinides and transuranics. The remaining residual waste will decay to the level of naturally background uranium in about 300 years [as opposed to about 350,000 years for high level wast coming out of today’s nuclear reactors]. Since humans have demonstrated our ability to design and build civil structures capable of lasting well beyond 300 years for several millennia now; confidence is very high in our ability to keep this waste ‘tight’ for 3 centuries.

Also during the conference, there were several scientific presentations explaining the PUREX flow-sheets – plutonium is never separated.

3. Partnering nations, those who are not enriching but receiving fuel from supplier states would benefit through security of fuel supply and an agreement that the supplier states would take back the fuel for reprocessing.

A point made by many is that the real challenge rests at the back end of the fuel cycle [waste]. If GNEP can’t offer anything new there, then it really isn’t offering much at all. For example, provided a country remains within the good graces of the UN Security Council, they currently have no problem getting a reactor and fuel through the industrial partners in existence today [Westinghouse, AREVA, GE, etc.]. GNEP doesn’t offer much new in this regard. However, through GNEP as it is defined today, some of the old significant challenges still remain. Unless something novel is proposed for the back end, states will still have to develop a long-term, high-level waste solution for the residual waste post-reprocessing. [The US has no policy to keep all this waste.] Individual, high level nuclear waste repositories are simply not an option for small, developing states.

Some opportunities for Australia.

Get back into enrichment

Presentations involving enrichment at this conference show expected demand increasing dramatically over the coming years together with some older enrichment capacity that must be upgraded or replaced in the near future. Several companies are already expanding their enrichment services to meet projected demand. Presentations included the status of the new National Enrichment Facility in New Mexico being constructed by Louisiana Enrichment Services. But there appears to be scope for more.

However, while Australia has proven our scientific ability relating to enrichment, we lack any demonstrated industrial capacity in this regard. Is it reasonable to think we can fast-track our related scientific achievements to an industrial capacity in time to meet the demand [and with competing countries and companies already moving in this area]? Partnering with existing companies to host facilities of their design and technology may be more reasonable.

There may also be advantages to becoming an enrichment state, eventually supplying our own fuel for example.

Reprocess & Burn

With enrichment, Australia may also then get into reprocessing and fast burner industries. Again, to me this seems a HUGE industrial leap, especially when the high level schedule/implementation ambitions of the GNEP programme are considered. Australia has no technology base with respect to the design of nuclear reactor facilities [ even OPAL was Argentinean design]. I doubt countries/companies in possession of such technology would be eager to export it. This is probably the least likely activity to be seen domestically in Australia.

Long Term Waste Management

Here, Australia could take advantage of the starkest features of our country – vast emptiness, extreme isolation and geologic stability. If there was ever an opportunity to see emptiness and isolation as a resource, the nuclear fuel cycle is it.

Compact to begin with, spent nuclear fuel is rarely seen as waste any longer. Trends are definitely moving toward reprocessing, with new reactor designs aiming to burn recycled fuel – supported by research in Japan for example as well as ongoing recycling/reprocessing activities in many countries around the world [several of these countries are in the midst of expanding their capabilities in this regard]. But the final waste from reprocessing activities still needs a home. As I mentioned above, this final waste will be of significantly lower volume, lower activity and generate less heat. In a few hundred years it will achieve the same activity as the uranium under our feet at this very moment.

Should Australia consider and eventually agree to host such a site for, as an example, participating GNEP countries [a ‘supranational repository’]; the boost to that endeavour would be considerable. The international demand for such services could result in tremendous benefits for Australia. This is worthy of serious consideration – particularly when you consider that we will need a waste storage facility [or certainly access to such services] to handle the output from our use of lifesaving radio-pharmaceuticals as well as other non-power nuclear industrial products.

This is not a new topic to Australia, as discussed in this radio interview from 1999. But with reprocessing, we are speaking of a different breed of horse altogether.

So in conclusion, GNEP is not a ‘gate’ between countries and nuclear power, but rather one of several paths to obtain it. As it is being promoted at the moment, choosing this path will be 100% voluntary. Therefore, if it is to achieve the ambitious strategic goals mentioned above [as well as at the conference], GNEP MUST become the path of least resistance as perceived by non-nuclear states with nuclear power ambitions. This certainly seems improbable without a long term solution to the final waste streams, and in particular, highly active waste.

Feasibility of Enrichment (in Queensland??)

The World Nuclear Association is reporting a planed Uranium Enrichment feasibility study about to be launched by Nuclear Fuel Australia Limited.

Plans by the new company, Nuclear Fuel Australia Limited, which is headed by Clarence Hardy, envisage a 3 million separative work unit (SWU) per year plant using Urenco 6th-generation centrifuge technology. Hardy told World Nuclear News that Urenco's National Enrichment Facility (NEF) under construction in New Mexico, USA, made a "very good reference model" for the potential future plant.

Valued at around A$2.5 billion ($2.1 billion), the project could see a A$2.0 billion enrichment plant and a A$500 million conversion plant, which would transform uranium oxide into the uranium hexafluoride (UF6) feed required for gas centrifuge enrichment. Construction is envisaged in the report as starting in 2010 with full capacity being reached in 2015.

Hardy emphasized that NFAL as a company was solely concerned with the feasibility study, and had made no agreements with Urenco or any domestic uranium producer. He said the NFAL preliminary study does not discuss potential sites for the plants.
This work picks up where a previous effort in the early 1980's left off. Some media outlets are reporting that work as some sort of clandestine activity [I wasn't in Australia at the time, so I can't comment]. But I doubt that was the case. If you read the entire WNA article linked above you will see that the 1980's work had government support. Also, let's not forget SILEX [domestic Australian technology recently licensed to GE/America]. So enrichment technology is nothing new to Australia.

Considering the size and scope of the facility being considered... I'd say this is but another example of high end employment opportunities involved within the nuclear fuel cycle.

As one would expect. Kevin Rudd is denigrating this announcement and those behind it. At his side, I am not surprised to see Queensland Premier Peter Beattie. Between the two of them - you will hear the same tired anti-nuclear political rhetoric as I've already posted way too many times in this blog. Digging up the waste discussions while Australia's numerous coal plants continue to indiscriminately spew toxic, climate killing wastes into the air we all fill our lungs with - on average - 13 times a minute.

But the article linked just above also gives some airtime to Dr. Bruce Flegg, Member for Moggill. Dr. Felgg is accusing Peter Beattie of generating hysteria for purely political gains.
"I'm not sure Australians are so simple as Mr Beattie and others would like to portray them," Dr Flegg said.

"Why not at least look at whether this could be a future valuable industry for Queensland?"

Dr Flegg accused the premier of "selling short the future of the state". "We want to look at the science of it and make sure that if uranium enrichment were to be contemplated for Queensland that it can be delivered safely."

"Uranium enrichment is not an activity that should be tolerated in any of the residential or urban areas in the state of Queensland," Dr Flegg said.

I'd say Dr. Flegg is right. Especially when Mr. Beattie speaks of 'other options to address climate change' while his fingers quietly stroke the pen that approved new fossil fueled facilities like this one to be located near Braemar, Queensland.
