The Fukushima Daiichi nuclear disaster in 2011 occurred due to a loss-of-coolant accident. The circuits that provided electrical power to the coolant pumps failed causing a loss-of-core-cooling that was critical for the removal of residual decay heat which is produced even after active reactors are shut down and nuclear fission has ceased.
Two varieties of above-ground water tanks are seen at the back, and the workers are working in an underground storage pool. [ 2 ] Radioactive water from the Fukushima Daiichi Nuclear Power Plant in Japan began being discharged into the Pacific Ocean on 11 March 2011, following the Fukushima Daiichi nuclear disaster triggered by the Tōhoku ...
Contaminated water leakage from a flange type tank was found in the H4 area. [76] The incident was evaluated by the NRA as a provisional rating Level 3 on the eight-level INES. [77] In response to this incident, the NRA recommended that TEPCO should replace the flange type tank, which was prone to leak water, with a welded type tank. [78] On 28 ...
Roughly 81 million people live within a quarter-mile of an underground storage tank that's experienced at least one leak, based on the latest EPA data. Most tanks were made of steel in the mid ...
Computer simulations, from 2013, suggest "the melted fuel in Unit 1, whose core damage was the most extensive, had breached the bottom of the primary containment vessel and had even partially eaten into its concrete foundation, coming within about 30 cm (1 ft) of leaking into the ground". [53]
A leak in the head gasket - often called a "blown head gasket" - can result in a leak of coolant, the combustion gasses, or both. Blue smoke from the exhaust suggests that excess oil is entering the combustion chambers (although there are other possible causes than a head gasket leak). White smoke from the exhaust suggests that coolant is ...
The High Pressure Coolant Injection (HPCI) System consists of a pump or pumps that have sufficient pressure to inject coolant into the reactor vessel while it is pressurized. It is designed to monitor the level of coolant in the reactor vessel and automatically inject coolant when the level drops below a threshold.
The Reactor Protection System (RPS) is a system, computerized in later BWR models, that is designed to automatically, rapidly, and completely shut down and make safe the Nuclear Steam Supply System (NSSS – the reactor pressure vessel, pumps, and water/steam piping within the containment) if some event occurs that could result in the reactor entering an unsafe operating condition.
