The U.S. Nuclear Regulatory Commission is issuing for public comment a draft, plant-specific supplement to the Generic Environmental Impact Statement (GEIS) related to the 20-year renewal of the operating license for Grand Gulf Nuclear Station Unit 1 (GGNS).
The 1,071-MW plant is located in Claiborne County, Miss. Possible alternatives to the proposed action (which is license renewal) include no action and reasonable alternative energy sources, the commission said in a notice to be published in the Dec. 12 Federal Register.
The NRC staff plans to hold two public meetings on Jan. 29, 2014, in Port Gibson, Miss., to present an overview of the draft plant-specific supplement to the GEIS. Comments need to be submitted by Feb. 11, 2014.
In October 2011, Entergy Operations submitted the application to the NRC to issue a renewed operating license for this unit. GGNS is a single-unit plant that began commercial operation in July 1985. The existing license will expire on Nov. 1, 2024, with Entergy seeking an additional 20 years.
The original application submitted in 1972 for GGNS was for a two-unit nuclear facility. Construction on Unit 2 was halted before completion in 1979. The majority of the Unit 2 power block buildings were completed, along with the outer cylindrical concrete wall of the reactor containment building. The switchyard was designed and constructed for two units.
The GGNS nuclear reactor system is a single-cycle, forced-circulation, General Electric Mark III boiling water reactor.
