“This Royal Commission will be hearing evidence in a vacuum: the draft terms forbid it from considering any aspects of the industry we are familiar with (mining), and insist it consider aspects of the hypothetical future next generation reactors, which are so wonderful that no-one is building them commercially.”, said Roman Orszanski, Climate & Energy campaigner for Adelaide Friends of the Earth.

FoE Australia’s very own Jim Green looked at the possibilities for the new generation of nuclear power reactors (since the current crop are unlikely to impress anyone), and found the kinds being spruiked by pro nuke advocates in SA have a few problems.

Integral Fast Reactors … it gets ugly moving from blueprint to backyard

Integral Fast Reactors (IFRs) are a case in point. According to the lobbyists they are ready to roll, will be cheap to build and operate, couldn’t be used to feed WMD proliferation, etc. The US and UK governments have been analysing the potential of IFRs.

The UK government found that:

• the facilities have not been industrially demonstrated;
• waste disposal issues remain unresolved and could be further complicated if it is deemed necessary to remove sodium from spent fuel to facilitate disposal; and
• little could be ascertained about cost since General Electric Hitachi refuses to release estimates of capital and operating costs, saying they are “commercially sensitive”.

The US government has also considered the use of IFRs (which it calls Advanced Disposition Reactors – ADR) to manage US plutonium stockpiles and concluded that:

• the ADR approach would be more than twice as expensive as all the other options under consideration;
• it would take 18 years to construct an ADR and associated facilities; and
• the ADR option is associated with “significant technical risk”.

Unsurprisingly, the IFR rhetoric doesn’t match the sober assessments of the UK and US governments. As nuclear engineer Dave Lochbaum from the Union of Concerned

Scientists puts it: “The IFR looks good on paper. So good, in fact, that we should leave it on paper. For it only gets ugly in moving from blueprint to backyard.”

Small Modular Reactors … no-one actually wants to buy one

In any case, IFRs are yesterday’s news. Now it’s all about Small Modular Reactors (SMRs). The Energy Green Paper recently released by the Australian government is typical of the small-is-beautiful rhetoric:

“The main development in technology since 2006 has been further work on Small Modular Reactors (SMRs). SMRs have the potential to be flexibly deployed, as they are a simpler ‘plug-in’ technology that does not require the same level of operating skills and access to water as traditional, large reactors.”

The rhetoric doesn’t match reality. Interest in SMRs is on the wane. Thus Thomas W. Overton, associate editor of POWER magazine, wrote in a recent article:

“At the graveyard wherein resides the “nuclear renaissance” of the 2000s, a new occupant appears to be moving in: the small modular reactor (SMR). … Over the past year, the SMR industry has been bumping up against an uncomfortable and not-entirely-unpredictable problem: It appears that no one actually wants to buy one.”

Overton notes that in 2013, MidAmerican Energy scuttled plans to build an SMR-based plant in Iowa. This year, Babcock & Wilcox scaled back much of its SMR program and sacked 100 workers in its SMR division. Westinghouse has abandoned its SMR program. As he explains:

“The problem has really been lurking in the idea behind SMRs all along. The reason conventional nuclear plants are built so large is the economies of scale: Big plants can produce power less expensively per kilowatt-hour than smaller ones.

“SMRs must compete with cheap natural gas, renewables that continue to decline in cost, and storage options that are rapidly becoming competitive. Worse, those options are available for delivery now, not at the end of a long, uncertain process that still lacks [US Nuclear Regulatory Commission] approval.”

On 11 March it will be four years since a huge earthquake and tsunami caused the meltdown of Tokyo Electric Power Company’s (TEPCO) Fukushima Daiichi nuclear power plant. There is still no end in sight for the suffering of the people of Fukushima, but now it seems that the government and the electric power industry are moving inexorably towards the restart of reactors which have been shut down for most of the time since the accident.

“How can this be?”, incredulous observers might wonder. There are a few key factors which make it possible for the government to ignore the wishes of the bulk of the Japanese population for a nuclear phase out.

First, the current government, led by the Liberal Democratic Party (LDP), came to power not because of its support for nuclear energy, but because of the incompetence of its predecessor. The Democratic Party of Japan (DPJ) enjoyed a brief three years in government, a period which happened to coincide with the nuclear accident. Responding to public opposition to nuclear power, it declared a goal of phasing out nuclear energy by 2039, but due to its many other failings it was decimated in December 2012 elections and has failed to recover since. The LDP has returned to the pre-eminent position it has occupied for most of the last 60 years as Japan’s leading party and, because it has no challengers, it is riding roughshod over the public will.
