..., and seismic responses were negligible. Note that a Unit 2 reactor building explosion did not occur, and this fact is questionably attributed to the destructive removal of one of the walls of Unit 2 due to the earlier Unit 1 explosion. All of these explosions were ignited by fluid transients that exploded...

... processes, nuclear reactions, and thermal-fluid transients autoignite explosions. Research evaluated increasingly complicated accidents. First, piping explosions occurred at Hamaoka and Brunsbuttel. Fluid transients compressed oxygen and flammable hydrogen to heat these gases to autoignition, where...
