Japan signaled on Wednesday it would scrap a costly prototype nuclear reactor that has operated for less than a year in more than two decades at a cost of 1 trillion yen ($9.84 billion). Tokyo believes it would be difficult to gain public support to spend several hundreds of billion yen to upgrade the Monju facility, which has been plagued by accidents, missteps and falsification of documents, Reuters reported. There is also a strong anti-nuclear sentiment in Japan in reaction to the 2011 Fukushima atomic disaster and calls to decommission Monju have been growing in the ruling Liberal Democratic Party, with scant results from using around 20 billion yen of public money a year for maintenance alone. Monju was designed to burn plutonium from spent fuel at conventional reactors to create more fuel than it consumes. The process is appealing to a country whose limited resources force it to rely on imports for virtually all its oil and gas needs.
