The Nuclear and Industrial Safety Agency, in its first approval of stress tests for nuclear facilities, said Monday the level of quake and tsunami resistance of two reactors at the Oi power plant in Fukui Prefecture is adequate.

NISA submitted its report, which basically recommends restarting units 3 and 4 at the plant operated by Kansai Electric Power Co., to the Nuclear Safety Commission of Japan. After the commission approves the report, NISA will ask local governments for permission to fire the reactors back up.

Whether or when the reactors will resume operations remains unclear because it will be difficult to gain local residents' support due to the Fukushima nuclear disaster continuing since last March.
