The Grand Gulf Nuclear Generating Station ( Engl. Grand Gulf Nuclear Generating Station ) with a boiling water reactor , that of General Electric was built, is located near Port Gibson in Claiborne County in the US state of Mississippi on the east bank of the Mississippi River . Unit 1 of the nuclear power plant is one of the most powerful reactor units in the world with a gross electrical output of 1500 megawatts .
history
The reactor in Grand Gulf is the largest boiling water reactor in the United States and is owned by electricity and gas utility Entergy . Construction began on September 4, 1974. The reactor was commissioned on October 20, 1984. It is cooled by two lakes and also by a 158 meter high cooling tower . Originally two blocks were under construction. The second block was not completed due to the meltdown in Three Mile Island and the resulting increase in construction costs due to increased safety requirements. Construction was interrupted in 1979 and officially canceled in 1990.
In 2002 the Nuclear Regulatory Commission approved a net power increase of 1.7% from 1210 MW to 1232 MW for the reactor. An application for an extension of the operating license by 20 years was announced by the operator and is (as of October 2012) in process. The plant has (as of October 2012) an operating license until 2024.
Since September 22, 2005 it was planned to build an Economic Simplified Boiling Water Reactor ( ESBWR ) at the site as part of the Nuclear power 2010 program , this is a further developed boiling water reactor from General Electric. On February 27, 2008, Entergy applied for a combined construction and operating permit and on January 9, 2009, an interruption of the approval process in order to re-evaluate alternative reactor technologies.
Accident
In April 2011, after heavy rains in the region, water was found contaminated with tritium in the machine house of the second block, which was never completed . Its origin is still unclear.
