NISA meaning in Academic & Science ?

The Nuclear and Industrial Safety Agency (NISA) (原子力安全・保安院, Genshiryoku Anzen Hoanin) was a Japanese nuclear regulatory and oversight branch of the Agency for Natural Resources and Energy under the Ministry of Economy, Trade and Industry (METI). It was created in 2001 during the 2001 Central Government Reform.

Especially after the Fukushima Daiichi nuclear disaster, NISA was criticized as having a conflict of interest, given that it was part of METI, which is also responsible for promoting nuclear power. As a consequence, it was decided on June 20, 2012 that NISA would be abolished and that it would be replaced by a new agency, under the Ministry of the Environment in September 2012. The Nuclear Regulation Authority (NRA) was founded on September 19, 2012.

NISA, and now NRA, main office is located in Kasumigaseki, Chiyoda, Tokyo working with the Japanese Atomic Energy Commission (JAEA) as well as providing other functions. The safety authority also has regional offices. It performs oversight for industry as requested by the Japanese government.
