HIAD Facility - Application Type: Power Plant
The event occurred during the decommissioning of a nuclear power plant. It involved a tank containing 100 kg of residual sodium from the decommissioned experimental nuclear reactor which was using…
At about 3:15 p.m. on Dec. 3 2003, personnel in the Expended Core Facility at the Naval Reactors Facility heard a loud, unexpected noise. Upon investigation, personnel found an irradiated material…
Explosion in condenser area two hours after the unit tripped (due to a stator earth fault). The stator earth fault had damaged two hydrogen cooler tubes, which allowed hydrogen to pass from the…
A contained explosion in a hydrogen tank occurred at the thermal generation plant
The event occurred in the steam condensing line of the residual heat removal system the nuclear reactor. Radiolysis generated hydrogen and oxygen which then accumulated in high concentration in the…
A hydrogen explosion had ruptured a pipe in the core spray system at the Brunsbttel BWR in Germany. Although the control room instrumentation had at the time indicated a leak of radioactive steam,…
A hydrogen-cooled electricity generator exploded inside a coal-fired power plant killing two workers and injuring fifty others. An investigation into the incident found that a hydrogen gas leak may…
Explosion of hydrogen at slip ring end of an alternator. It was caused by a hose fracture within the generator casing, which led to a discharge of water into the casing and subsequent electrical…
An hydrogen explosion occurred within the off-gas system, causing the stop of the sump pump; subsequently both trains of the standby gas treatment system were declared inoperable. The sump is part of…
A hydrogen explosion caused burns contaminated with radioactive dust to a member of the plant's maintenance crew. Three other workers escaped injury.The accident occurred in the basement of the…
A hydrogen explosion occurred at a 585-MW coal-fired supercritical unit and caused one fatality, injuries to 10 other people, and significant damage to several buildings. The explosion occurred…
A tank leaking hydrogen at an electrical power plant exploded.
At 11:15 pm, an explosion followed by fire occurred in the vicinity of the measurement transformer on an isolated 90,000 V electrical oil transformer at a plant manufacturing technical polymers.…
This entry reports only the role of hydrogen in this nuclear accident. For a short description of the initial causes and the incident evolution, see at field pre-event summary and for a much more…
Explosion in generator area, thought to be hydrogen leak as a result of radial lead seal failure. Extensive plant damage.
A hydrogen leak occurred on the a coolant pipe of an electrical generator located in the turbine building, at 200 m from the reactor. Because of the welding works ongoing at that moment on the pipe…
The incident occurred at the hydrogen coolant circuit, when purging the hydrogen with carbon dioxide and air, aiming at finding a leak. Following a preliminary investigation, the power plant company…
An in-tank explosion occurred in a gaseous waste decay tank while the plant was in cold shutdown. The gaseous hydrogen present in the tank formed a flammable mixture and ignited due to air…
This incident occurred at the hydrogen production and storage unit of (probably) a power plant using hydrogen as a coolant of the turbine-generator system. Hydrogen was produced probably by water…
The accident occurred in a disposal storage for contaminated waste, consisting in a 65-metre shaft flooded with seawater. At the origin of the explosion was the reaction with water of at least two…
