The Sendai Nuclear Power Plant (川内原子力発電所 Sendai genshiryokuhatsudensho?, Sendai NPP) is a nuclear power plant located in the city of Satsumasendai in the Kagoshima Prefecture. It is owned and operated by the Kyūshū Electric Power Company.

The plant is on a site of 1.45 km2 (358 acres), employs 277 workers, and indirectly employs 790.

The reactors are of the 3-loop M type pressurized water reactor, built by Mitsubishi Heavy Industries.[1]

Reactors on Site[edit]

Name Reactor Type Commission date Gross Power Rating Core Tonnage Price to build
Sendai-1 PWR July 4, 1984 890 MW 72 tons/uranium dioxide 278.7 billion Yen
Sendai-2 PWR November 28, 1985 890 MW 72 tons/uranium dioxide 228.7 billion Yen

Stress-tests published in 2011-restart crises[edit]

On 14 December 2011 the Kyushu Electric Power Company published the outcome of the primary safety assessments or "stress-tests" for three of its suspended nuclear reactors: two of them located at the Sendai Nuclear Power Plant in prefecture Kagoshima Prefecture, the third at was located the Genkai Nuclear Power Plant in Saga prefecture. The reports were sent to the Japanese Nuclear and Industrial Safety Agency. The papers were also sent to the local authorities of the prefectures where the plants were located, because the reactors are not allowed to be restarted without their consent. According to the test, the reactors could withstand a seismic shock of 945 to 1,020 gals and tsunami-waves of a height of 13 to 15 meters. The power company asked its customers to reduce their power-consumption by at least 5% after 26 December, because at 25 December the number 4 reactor in Genkai would be taken out of operation for regular check-ups. Nuclear power generation did account for about 40 percent of the total output of the company, according to company official Akira Nakamura. He said that restarting reactors was crucial for them, and that the company will do all it can do to win back public-trust. However, Hideo Kishimoto, the mayor of Genkai said that it would be difficult to resume operations. He asked Kyushu Electric to disclose their practices in full, besides their efforts to prevent future accidents.[2]

Restarting[edit]

On 10 September 2014 the Japanese Nuclear Regulation Authority declared that the plant was safe to be operated. Actual operation was expected by the end of 2014, following approval of local authorities. [3]
