Columbia Generating Station

F1

Active reactors ( gross ):

The nuclear power plant called Columbia (English Columbia Generating Station ), or even Washington State Power Plant ( WSPP ), is a nuclear power plant with a boiling water reactor. The nuclear power plant is located in Hanford in Washington state. The area is located in the immediate vicinity of the Hanford Site. This huge area was once the largest U.S. production for U.S. nuclear weapons complex; he is radioactive heavily contaminated. ( List here )

The nuclear power plant was built in 1972 by General Electric. It is operated by Energy Northwest. The nuclear reactor was first critically on 19 January 1984. He went on May 27, 1984 to the network. He owns a Mark II containment, a further development of in certain respects classified as unsatisfactory previous Mark I containment; it is very similar to the containment of the Swedish ASEA BWRs.

The power plant is cooled by six cooling towers.

The NPP received on 20 December 1983, a operating license (operating license) from the Nuclear Regulatory Commission (NRC ). On January 19, 2010 North West requested the NRC to extend the operating licenses for 20 years.

Incidents

In October 1998, a water hammer brought the valve of an auxiliary system in the reactor building line to the bursting point. About 650 cubic meters of water flowed out and flooded the pumping chambers of the low-pressure emergency cooling and the condensation chamber pumps whose doors were not designed to withstand such water masses and departed. The reactor was cooled down using the normal operating systems; had this but failed, an emergency cooling would have been very difficult.
