The Kashiwazaki-Kariwa Nuclear Power Plant (柏崎刈羽原子力発電所 Kashiwazaki-Kariwa genshiryoku-hatsudensho?, Kashiwazaki-Kariwa NPP) is a large, modern (housing the world's first ABWR) nuclear power plant on a 4.2-square-kilometer (1,038 acres) site including land in the towns of Kashiwazaki and Kariwa in Niigata Prefecture, Japan on the coast of the Sea of Japan, from where it gets cooling water. The plant is owned and operated by Tokyo Electric Power Company (TEPCO).
It was the largest nuclear generating station in the world by net electrical power rating.
It was approximately 19 km (12 mi) from the epicenter of the second strongest earthquake to ever occur at a nuclear plant, the Mw 6.6 July 2007 Chūetsu offshore earthquake. This shook the plant beyond design basis and initiated an extended shutdown for inspection, which indicated that greater earthquake-proofing was needed before operation could be resumed. The plant was completely shut down for 21 months following the earthquake. Unit 7 was restarted after seismic upgrades on May 9, 2009, followed later by units 1, 5, and 6. (Units 2, 3, 4 were not restarted).
After the April 2011 earthquake, all restarted units were shut down and safety improvements are being carried out. As of December 2016[update] no units are restarted and no units are expected to restart sooner than in 2017.
