Demise: nuclear plutonium alive

South Carolina is suing the U.S. government to recover $100 million in fines it says the Department of Energy owes the state for failing to remove one metric ton of plutonium stored there.  The lawsuit was filed on August 7, 2017.

Congress approved fines of $1 million per day for the first 100 days of each year through 2021, beginning 2016, if the weapons-grade plutonium was not removed from the Savannah River Site at the state’s border with Georgia, the attorney general’s office said.   The federal government cannot break its obligations and “leave South Carolina as the permanent dumping ground for weapons-grade plutonium” said in the complaint.

Built in the 1950s, the U.S.-owned Savannah River Site processes and stores nuclear materialss.  A U.S. treaty with Russia in 2000 [The Plutonium Disposition Agreement]* required each country to dispose of 34 metric tons of weapons-grade plutonium, left over from the Cold War.

The United States began building a mixed oxide fuel fabrication facility, known as the MOX project, at the Savannah River Site to dispose of weapons-grade plutonium by mixing it with uranium to form safer fuel pellets for use in commercial nuclear reactors.  But the project is years overdue and billions over budget, and the technology for the new fuel fabrication is not fully developed. Russian President Vladimir Putin in October 2016 pulled out of the plutonium pact amid rising tensions over Ukraine and Syria.  The Trump administration proposed in the fiscal year 2018 budget to scrap the project and pursue diluting the plutonium and disposing it underground, an alternative called for by the Obama administration.

Dashing the Japanese Dream: nuclear self-sufficiency

Mihama Nuclear Plant, at Fukui Japan

Japan on December 21, 2016 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.  The move to shut the Monju prototype fast breeder reactor in Fukui prefecture west of Tokyo adds to a list of failed attempts around the world to make the technology commercially viable and potentially cut stockpiles of dangerous nuclear waste.

“We do not accept this,” Fukui Governor Issei Nishikawa told ministers involved in the decision.”…Nishikawa strongly backed the project because of the jobs and revenue it brought to a prefecture that relies heavily on nuclear installations. He said decommissioning work for Monju would not start without local government approval.  Four conventional commercial nuclear stations lie in close proximity to Monju, earning Fukui the nickname “nuclear alley.”

The Fukushima crisis sparked strong anti-nuclear sentiment in Japan, making it harder to pursue projects like the Monju facility which has faced accidents, cover-ups and regulatory breaches since construction began in 1985.  The plant was built to burn plutonium derived from the waste of reactors at Japan’s conventional nuclear plants and create more fuel than it used, closing the so-called nuclear fuel cycle and giving a country that relies on overseas supplies for most of its energy needs a home-grown electricity source.

Who is Watching North Korea

The 38 North, a US institute monitoring North Korea said that the country appears to be beginning or planning to extract plutonium, the core material of a nuclear bomb, at a nuclear plant in Yongbyon, north of Pyongyang.  Satellite imagery dated April 11,  2016 shows a vehicle loaded with tanks or casks in the premises of a nuclear reprocessing facility, according to the 38 North website operated by Johns Hopkins University’s US-Korea Institute in Washington.  “Such tanks or casks could be used to supply chemicals used in a reprocessing campaign intended to produce additional plutonium, haul out waste products or a number of other related activities,” the institute said.  Similar vehicles were observed in the early 2000s, it said, when North Korea extracted plutonium apparently as part of its nuclear programmes.

On April 4, 2016 the institute said plumes were detected from the reprocessing facility fueling the speculation that Pyongyang has engaged in additional production of plutonium.
