Westinghouse Electric Company announced that the Toshiba Corporation Keihin manufacturing facility in Yokohama, Japan, has successfully completed the manufacture of the core barrel for the Westinghouse AP1000® nuclear power plant under construction at South Carolina Electric & Gas Company’s (SCE&G)(NYSE:SCG), V.C. Summer Unit 2 in Jenkinsville, South Carolina. The core barrel resides inside the reactor vessel of the AP1000 plant and houses the reactor’s fuel.
The completion of this major component is significant for the Toshiba facility, which has extensive experience in manufacturing components for boiling water reactors, because this is the first component manufactured for a pressurized water reactor. In addition to being manufactured according to the highest standards, it was also completed at the end of January, which was well before the April shipping schedule.
SCE&G, principal subsidiary of SCANA Corporation, and Santee Cooper received approval for combined construction and operating licenses (COLs) from the Nuclear Regulatory Commission (NRC) for two new nuclear units at V. C. Summer Nuclear Station in 2012.
The NRC certified Westinghouse’s amended AP1000 design in Dec. 2011. The AP1000 is a 1,100 megawatt electric pressurized-water reactor that includes passive safety features that would cool down the reactor after an accident without the need for electricity or human intervention.
Westinghouse and Shaw Group currently are building four new nuclear units in the United States, with two units each at V.C. Summer and Southern Co.’s (NYSE:SO) Plant Vogtle. These projects represent the first contracts awarded in nearly 30 years for new nuclear builds in the U.S.
