H. B. Robinson Nuclear Generating Station


Active reactors ( gross ):

The plant HB Robinson (English HB Robinson Nuclear Generating Station ) is a nuclear power plant with a pressurized water reactor. The nuclear power plant is located near Hartsville in Darlington County in the U.S. state of South Carolina.


The plant HB Robinson 2 has a pressurized water reactor from Westinghouse. The owner is Carolina Power & Light Company 's ( CP & L). Construction began on 13 April 1967. Commissioning of the reactor was on 26 September 1970. The first unit of the power plant complex is a coal-fired power plant. The reactor block was later built to increase performance of the power plant. Both units use for cooling water intake to a specially created artificial lake.


Broke out on 28 March 2010 at Unit 2 during full load operation due to a cable failure, which led to an arc of fire. A triggered by the fire voltage collapse led to the failure of a main coolant pump, which led to rapid shutdown of the reactor. Following the fire, there was amplified by steam extraction on the Heizdampfleitungen of the reheater to a cooling of the primary circuit, resulting in a safety injection result. Reason that it came to these consequences after the cable has been severed, was the non-opening of a dome switch between two power rails. In the further course of events, there was a reduced supply of cooling water for the seals of the reactor coolant pumps, and a further cooling of the primary circuit. After the first fire occurred in the re- feed due to ground fault on a high-energy arc, which led to a second fire. Originally, the event of the U.S. Nuclear Regulatory Commission (NRC ) as INES 1 was classified, according to another study by the NRC classification was raised to INES 2. This has particularly been based on additional components with errors and shortcomings in controlling the interference by the shift personnel.
