Tokyo Electric Power Company Holdings, Inc.
Today, Tokyo Electric Power Company Holdings, Inc. received approval from the
Nuclear Regulation Authority for the test use of the reactor in preparation to confirm the
integrity verifications of systems including the pre-operational operator inspection to be
conducted after reactor startup.
Preparations for the reactor startup have been underway since the submission of the
pre-operational confirmation modification application on December 24, 2025. At 7:02
p.m. today, the control rods were withdrawn thereby initiating reactor startup.
We shall move forward with verifying the integrity of the plant facilities under
conditions that use actual steam and carefully cooperate with inspections conducted by
the Nuclear Regulation Authority.
As it has been approximately 14 years since the power station was in operation, we
will carefully verify the integrity of each and every plant facility while suitably addressing
any issues that arise and conveying information to the public during each step of the
startup process.
We remain fully committed to demonstrating through actions and results that we are
prioritizing safety at the Kashiwazaki-Kariwa Nuclear Power Station.
