NISA Mentions “Neptunium-239″ in August 29 Press Conference, EX-SKF, August 28, 2011
[...] The Nuclear and Industrial Safety Agency (NISA)’s daily press conference is ongoing (August 29). The NISA spokesman Moriyama mentions neptunium-239′s conversion ratio to plutonium-239 as 1 to 1.
According to the June 6 estimate by the NISA [see chart below] [...] Neptunium-239: 7.6×10^13 [...]
At a ratio of 1:1, Plutonium-239 releases are also 7.6 x 10^13, or 76 tera(trillion)becquerels.
23,000 higher than previous gov’t estimate
[...] According to the June 6 estimate by the NISA [see chart below]: Plutonium-239: 3.2×10^9 [3.2 billion becquerels] [...]
The amount of plutonium-239 has increased 23,000-fold. [...]
*Via EX-SKF* UPDATE on 8/29/2011: NISA backtracked in the joint conference (TEPCO/government) in the afternoon, and now says it’s not sure about the conversion rate of neptunium-239 into plutonium-239.
