Monju FBR decommissioning

Post by Kirk Sorensen » Feb 18, 2016 1:33 pm

300 billion yen price tag projected for scrapping Monju
Education and science minister Hiroshi Hase said the Japan Atomic Energy Agency estimates it will cost around 300 billion yen to scrap the Monju fast-breeder reactor over 30 years.

The estimate was made by the agency in 2012 but had never been disclosed to the public.

The ministry has been in the middle of discussions about how to ensure safe operations of the trouble-prone experimental reactor in Tsuruga, Fukui Prefecture, after getting a warning from the Nuclear Regulation Authority last November.

The NRA said Monju needs a new operator and steps to guarantee its safety, including an option to close the facility if a new entity can’t be found to run it.

The decommissioning cost includes 130 billion yen for demolishing the reactor and 20 billion yen to remove the fuel, according to the ministry. If Monju continues operations, about 20 billion yen would be needed every year to maintain it.

I think that they should get Russian experts to operate it. It would be preferable to use up some of their plutonium stocks before decommissioning it. They could use the rest as Th-Pu MOX in other reactors.

From the article, Stephen Stapczynski and Emi Urabe wrote:“These turn out to be very expensive technologies to build,” Allison MacFarlane, a former chairman of the U.S. Nuclear Regulatory Commission, said by e-mail. “Many countries have tried over and over. What is truly impressive is that these many governments continue to fund a demonstrably failed technology.”
How expensive to present and future generations for the accumulative global impacts of burning through geologic deposits of various forms of carbon that have powered and continue to power growing numbers of energy-hungry modern technological humans?

FBRs are expensive but not that much more expensive than LWRs.
Although it appears breeding is kind of unnecessary due to ample supplies of uranium globally.

The straw that broke the camels back (aside from Fukushima hysteria) was when they accidentally jammed the fuel loader in the RPV hole a while back, calling for a ton of work to look at how much repair work would be necessary. And the bill for the repair looked bad. If that hadn't happened, Monju would be scheduled up for reactivation like other reactors in japan, assuming it hadn't restarted for a while before the earthquake.

Kinda hard to do the same kind of damage with a liquid fuel...

Japan pulls plug on Monju, ending $8.5 billion nuclear self-sufficiency push
Japan on Wednesday formally pulled the plug on an $8.5 billion nuclear power project designed to realize a long-term aim for energy self-sufficiency after decades of development that yielded little electricity but plenty of controversy.

Atomic panel: No need to rush for fast reactor
The Atomic Energy Commission met on Friday to assess a government decision made in December to scrap the trouble-prone Monju fast-breeder reactor. The government called for developing a new fast reactor to maintain the country's nuclear fuel recycling policy. Commission members said the government should consider how to make such reactors commercially viable. They said this would involve setting goals such as keeping costs lower than those of conventional reactors. Members also said utilities will likely stick to existing uranium reactors since supplies of their fuel are abundant. They added that they're unlikely to commit to a different type whose future is unclear.

Most uranium ores (except from Canada) have 100-200 ppm of uranium. To leave only a reasonable mining footprint, the uranium should be fully utilised. Indians know it from experience. If Monju is given up, the Japanese may have to go for an alternative.
Especially the Japanese, who have collected one of the major stocks of recovered plutonium should utilise it.

Breeders are really the holy grail of nuclear energy.
With Indian AEC, it is a thorium breeder.
A medium term option for Japan would be use of thorium-Pu(RG) fuel in existing reactors(PWR).
http://dae.nic.in/writereaddata/.pdf_38 refers.
With Pu(RG) in stock, it would be a safe and economical option.
