An explosion is a rapid expansion in volume of a given amount of matter associated with an extreme outward release of energy, usually with the generation of high temperatures and release of high-pressure gases. Explosions may also be generated by a slower expansion that would normally not be forceful, but is not allowed to expand, so that when ...
A nuclear explosion is an explosion that occurs as a result of the rapid release of energy from a high-speed nuclear reaction.The driving reaction may be nuclear fission or nuclear fusion or a multi-stage cascading combination of the two, though to date all fusion-based weapons have used a fission device to initiate fusion, and a pure fusion weapon remains a hypothetical device.
When including settlements ($2.1 billion), costs of repairs, deferred production, and fines, the explosion is the world's costliest refinery accident. The direct cause of the explosion was the ignition of a heavy hydrocarbon vapor cloud which emanated from raffinate liquids overflowing from the top of a blowdown stack. The source of ignition ...
The explosion of Space Shuttle Challenger, taken from the TV-3 camera. At T+72.284, the right SRB pulled away from the aft strut that attached it to the ET, causing lateral acceleration that was felt by the crew. At the same time, pressure in the LH2 tank began dropping. Pilot Mike Smith said "Uh-oh," which was the last crew comment recorded.
At 15:36 JST on 12 March, there was an explosion in the reactor building at Unit 1 that was primarily directed sideways. [47] The side walls of the upper level were blown away, leaving in place only the vertical steel framed gridworks. Despite the damage, the remaining walls were relatively intact compared to later explosions at Units 3 and 4.
