Fukushima Disaster March 11th – March 21st Chronology, NRC, Published May 15, 2012: NOT FOR PUBLIC DISCLOSURE [...] 2011/03/20 at 18:04:33 ET — “Watches youtube videos comparing Unit 1 and Unit 3 explosions. Unit 3 much larger, initiating event and then 3 loud bangs.”
Chris Gifford to Infrastructure Planning Commission (UK) (pdf), engineer and risk management consultant, March 14, 2012: In my paper Fukushima Dai-ichi V4 I quoted six authorities who share the opinion that nuclear explosion of fissile material out of control is possible. […] Zhores Medvedev in a preface to the 2011 edition of ‘The Legacy of Chernobyl’ describes the Chernobyl explosion as a nuclear explosion […] the record shows that Dr Webb’s [who worked on US Navy nuclear reactors] assertion that nuclear explosion was possible was not disputed by Mr Rimington nor by two senior HM Inspectors of Nuclear Installations. […] Professor Jack Harris, FRS, FEng, was a nuclear metallurgist involved in the design of British gas cooled reactors [supported] Ross Hesketh’s position on the possibility of a nuclear explosions in nuclear reactors […] Sir John Hill when Chairman of the Atomic Energy Authority in the UK […] wrote in the house journal of the Authority in 1992: “When the Americans chose graphite moderated water cooled piles for plutonium production they recognised that a failure of the water supply or control system could result in prompt criticality and a nuclear explosion such as happened 40 years later at Chernobyl.”
