HIAD Facility - Application Type: Power Plant
In an electricity production plant, a hydrogen leak from a tank explodes forming a fireball. The explosion was in a turbine of one of the electric units (800MW each). The Unit is damaged.
There was a massive explosion at one of the generator-turbine units of a coal-based power station. Undetected hydrogen leak from the generator was identified as a major trigger.According to the news…
Rockville, Maryland, on June 9th, the control panel door for the 32 hydrogen dryer blew off due to a small hydrogen explosion. No one was injured in the event, which occurred in the non-nuclear side…
A catastrophic failure of the low pressure turbine followed by fire and flooding severely damaged the generator. The main turbine automatically tripped due to an erroneous mechanical over speed…
Piping breakage at atomic power plant- Steam piping (inside diameter: 15 cm; thickness: 1.1 cm) of a heat exchanger for removing residual heat from a reactor was broken during the test of a high…
Leak from faulty hydrogen seal ignited by short circuit between inboard slip ring and outboard slip ring radial lead connection. Hydrogen flame caused damage to brush gear assembly and inboard slip…
Unit tripped on-load due to serious fire between alternator and number 12 bearing. Fire extinguished by fire brigade. No injuries. Serious site damage was sustained to in CT chamber and alternator…
At a nuclear power plant, a fire occurred in the station's hydrogen storage facility while the plant was operating at 100% power. The fire was reported to the control room by a non-licensed operator…
A technical failure in the High-Pressure turbine blades caused high vibrations in lubricating oil pipes. Some pipes broke off and the oil leak caught fire from hot surfaces. Also the generator's…
An isolation failure in starter coil of the high voltage generator induced an electric arc to the hydrogen supply line, with consequent fire and melting of the line.
A short circuit occurred in a bus bar system in a transformer building, causing a fire in adjacent switches. This was followed by the tripping out of the three refinery turbo-alternators, cutting off…
A hydrogen skid was placed into service in a nuclear power plant, outside the controlled area. This skid, like seven others, was located in a gas cylinder storage facility. It was supplied by several…
Severe hydrogen ingress into the stator coolant system resulted in a fire in the stator coolant head tank, ignition source unknown. No injuries to personnel. Minimal damage to plant.
A hydrogen generator overheated during testing and started a small fire in a power plant.
The incident occurred in the turbine-generator hall of a nuclear power plant. Hydrogen leaked from the alternator and ignited.The hydrogen line was purged to stop the leak. The plant employees were…
On April 29, 1991, a nuclear Power Plant experienced a main generator hydrogen fire. Although a senior reactor operator (SRO) and auxiliary operators from another shift were available immediately,…
Hydrogen ignition during welding on a VSC-24 spent fuel cask Pursuant to 10 CFR 72.210 - fuel in an independent spent fuel storage installation at its Point Beach Nuclear Power Plant. The inspection…
[NOTE: the sources are not completely clear in describing the system involved in this incident ; the following is the most plausible option according to HIAD validator]The explosion happened in two…
Maintenance works were ongoing after an outage at a turbine and generator unit of the plant. Fifteen maintenance mechanics were working at that time on the unit. An access cover was removed causing…
The explosion occurred while maintenance personnel were grinding a high-pressure injection (HPI) pipe, which had been recently cut at approximately 18 inches from the nozzle connecting the HPI pipe…
