Japan’s Plutonium Plan Hits New, Local Obstacles

Activists protest the arrival of mixed-oxide fuel at a Japanese nuclear power plant last June. New, local steps against the possible use of MOX fuel in Japan could complicate efforts by Tokyo to justify increased production of plutonium, an expert said.

Ja­pan’s case for stock­pil­ing plutoni­um risks be­ing un­der­cut by new, loc­al moves to stop the na­tion’s power plants from run­ning on the bomb-us­able ma­ter­i­al.

Ja­pan­ese com­munity of­fi­cials de­scribed new leg­al steps in op­pos­ing the use of mixed-ox­ide fuel — a plutoni­um-urani­um blend con­sidered po­ten­tially more haz­ard­ous than oth­er re­act­or ma­ter­i­al — as Prime Min­is­ter Shinzo Abe’s gov­ern­ment pre­pared to au­thor­ize the first re­act­iv­a­tion of atom­ic sites since the 2011 Fukushi­ma plant dis­aster. The city of Hakod­ate last week sued to stop work on a nearby MOX fuel re­act­or, and Shizuoka pre­fec­ture’s gov­ernor said he wants to re­verse his pre­de­cessor’s ap­prov­al of its use.

The moves came as Abe’s ad­min­is­tra­tion pre­pared as soon as Fri­day to fi­nal­ize an en­ergy policy call­ing for the sep­ar­a­tion of ad­di­tion­al plutoni­um from nuc­le­ar waste, the New York Times re­por­ted. This ties in with the planned launch of the Rokkasho re­pro­cessing fa­cil­ity, which could gen­er­ate yet more plutoni­um on top of 9 tons it has stock­piled thus far, enough to power 2,000 nuc­le­ar arms.

One non­pro­lif­er­a­tion ex­pert said pub­lic op­pos­i­tion to MOX fuel is a re­l­at­ively re­cent de­vel­op­ment in Ja­pan. Re­l­at­ively few Ja­pan­ese re­act­ors are slated to run on the ma­ter­i­al, and the new loc­al steps could fur­ther un­der­mine the case for Rokkasho’s launch, Henry Sokol­ski, ex­ec­ut­ive dir­ect­or of the Non­pro­lif­er­a­tion Policy Edu­ca­tion Pro­ject in Wash­ing­ton, told Glob­al Se­cur­ity News­wire on Tues­day.

“There really is no prac­tic­al way to ir­ra­di­ate large quant­it­ies of the sur­plus plutoni­um any­time soon, with the re­act­ors they have or are plan­ning,” said Sokol­ski. “Giv­en how much plutoni­um they already have, plus what they in­tend to pro­duce, the idea that you can elim­in­ate these plutoni­um stocks in re­act­ors is pre­pos­ter­ous.”

He also noted China’s vo­cal op­pos­i­tion to any in­creased Ja­pan­ese plutoni­um pro­duc­tion.

Cor­rec­tion: This art­icle was up­dated to more ac­cur­ately char­ac­ter­ize the plutoni­um-sep­ar­a­tion com­pon­ent of Ja­pan’s Rokkasho fa­cil­ity and to in­clude ad­di­tion­al ex­plan­a­tion by Henry Sokol­ski.

Ethics Cops Clear Mueller to Work on Trump Case
15 hours ago

"Former FBI Director Robert Mueller has been cleared by U.S. Department of Justice ethics experts to oversee an investigation into possible collusion between then-candidate Donald Trump's 2016 election campaign and Russia." Some had speculated that the White House would use "an ethics rule limiting government attorneys from investigating people their former law firm represented" to trip up Mueller's appointment. Jared Kushner is a client of Mueller's firm, WilmerHale. "Although Mueller has now been cleared by the Justice Department, the White House may still use his former law firm's connection to Manafort and Kushner to undermine the findings of his investigation, according to two sources close to the White House."

Brennan Saw Russia Intelligence “Worthy” of Investigation

At an open hearing of the House Intelligence Committee, former CIA chief John Brennan said he saw information on Trump-Russia contacts that were worth a further look. "Having been involved in many counterintelligence cases in the past, I know what the Russians do. They try to suborn individuals," Brennan said. "And they try to get individuals, including U.S. persons, to act on their behalf, whether wittingly or unwittingly. And I was worried by a number of the contacts that the Russians had with U.S. persons, and so therefore by the time I left office ... I had unresolved questions in my mind."

"President Trump asked two of the nation’s top intelligence officials in March to help him push back against an FBI investigation into possible coordination between his campaign and the Russian government, according to current and former officials.
