The Hindenburg disaster is an example of a large hydrogen explosion. Hydrogen safety covers the safe production, handling and use of hydrogen, particularly hydrogen gas fuel and liquid hydrogen. Hydrogen possesses the NFPA 704's highest rating of four on the flammability scale because it is flammable when mixed even in small amounts with ...
On 15 March, an explosion was observed at unit 4 RB during site evacuation. A team later returned to the power station to inspect unit 4, but were unable to do so due to the present radiological hazard. [8]: 44 The explosion damaged the fourth-floor rooftop area of Unit 4, creating two large holes in a wall of the reactor building (RB). The ...
Experts soon agreed that the cause was a hydrogen explosion. [ 52 ] [ 53 ] [ 54 ] Almost certainly the hydrogen was formed inside the reactor vessel [ 52 ] because of falling water levels exposing zircaloy structures/fuel assembly cladding, which then reacted with steam and produced hydrogen, [ 55 ] with the hydrogen subsequently vented into ...
The hydrogen bomb, which carried the force of 50 million tons of conventional explosives, was detonated in a test in October 1961, 4,000 meters over the remote Novaya Zemlya archipelago above the ...
Explosion of unserviceable ammunition and other military items The explosion of the Castle Bravo nuclear bomb. 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 ...

Concrete debris from the March hydrogen explosion of the reactor building has been detected in the spent fuel pool. In June TEPCO discovered that the water in the pool was strongly alkaline: the pH had reached a value of 11.2. Leaching of calcium hydroxide (portlandite) or calcium silicate hydrate (CSH) from the concrete could have caused this.
The pressure-containing shell of the heat exchanger burst at its weld seams, expelling a large volume of very hot hydrogen and naphtha, which spontaneously ignited upon contact with the surrounding air. [2] The ensuing explosion was so violent that many in Anacortes felt the shock wave across Fidalgo Bay. A giant fireball lit up the sky above ...
