MATSUYAMA (Kyodo) — Economy, Trade and Industry Minister Hiroshige Seko on Saturday inspected a recently restarted reactor at the Ikata nuclear power plant in western Japan to assess the safety measures there.

Seko visited an observation deck that overlooks the entire complex of Shikoku Electric Power Co.’s plant in Ehime Prefecture, as well as a facility to store spent nuclear fuel in the radiation-controlled area and other locations.

Seko was briefed on a system to provide electricity in the event of earthquakes and other emergencies by Seizo Masuda, the chief of the plant, and expressed satisfaction at the multiple backups available.

The No. 3 reactor at the Ikata plant was reactivated on Aug. 12, having cleared a set of safety requirements imposed in the wake of the Fukushima Daiichi nuclear power plant disaster in 2011.

The 890-megawatt reactor shifted to commercial operation on Sept. 7 following final checks by the Nuclear Regulation Authority. The unit had not operated since it was taken off-line in April 2011 for regular checks.

Some snags occurred around the time of its reactivation, including a problem with a pump for the reactor’s primary cooling water and a leakage in a drainage pipe in related equipment.

The reactor is currently the sole unit in operation in Japan running on plutonium-uranium mixed oxide fuel, which contains plutonium extracted from reprocessing spent fuel.
