I read a Monju failure book.

I found and read Science team of Yomiuri Shimbun 読売新聞科学部's book 'ドキュメント「もんじゅ」事故' (in English, 'The Document of Monju accident'), Dec 8, 1996, around May 23, 2007.

The JNC's concealing wasn't new fact in 2007. It has been known.

The book was rare good one. It touched Toshiba Corp 'the failure part supplier'. Many other Monju failure books didn't touch Toshiba Corp. (Although the book only slightly touched Naruo Nishimura 西村成生.)

I knew a funny thing.
Toshiba Corp wasn't on main stream of FRB Monju.
On Monju design competition, Jan 1969, Toshiba Corp and Hitachi Ltd was the loser at 'Tank type reactor' and Mitsubishi Heavy Industries Ltd, Fuji Electric Co and Sumitomo Heavy Industries Ltd was the winner at 'Loop type reactor'.

1969's Japan was under the Mitsubishi Group administration ? 1969's Japanese PM was Eisaku Sato 佐藤栄作. (Although I've cared Eisaku Sato 'the Nobusuke Kishi 岸信介's younger brother' could be Toshiba President (to 1996) Fumio Sato 佐藤文夫's family member, since I later knew PM Sosuke Uno 宇野宗佑's daughter's husband, (current Diet member) Osamu Uno 宇野治, was a Toshiba person.)
Actually Japan repeats the (Toshiba Corp led) Mitsui Group administration and the Mitsubishi Group administration alternately prime minister by prime minister from before ? Like Junichiro Koizumi 小泉純一郎 was the PM under the Toshiba Corp (Mitsui Group) administration and Shinzo Abe 安倍晋三 was the PM under the Mitsubishi Group administration. Shinzo Abe's brother Hironobu Abe 安倍寛信 works Mitsubishi Corp. (I may be wrong because Keijiro Kishi 岸敬二郎 (1911 - 1927) and Iwao Kishi 岸巌 (around 1947 - 1949) of old Toshiba executive board may be PM Nobusuke Kishi's (or Shinzo Abe's) family members, but I can see PM Shinzo Abe battled against Toshiba Corp in 2 some cases and is suffering from Toshiba Corp's coup events.)
However, anyway, after 1999 Toshiba Corp (secretly) dominates Japan.
