Japan Atomic Power Co., operator of the idled Tsuruga nuclear plant in Fukui Prefecture, said Friday its group sales in the year that ended in March grew 4.3 percent from a year earlier to ¥152.43 billion, even though it failed to generate any electricity.

The company has not earned money from its electricity wholesale business because all three of its reactors remain offline in connection with the triple-meltdown calamity that started in 2011 at Tokyo Electric Power Co.'s Fukushima No. 1 atomic plant, but its "basic fees" from several regional utilities with contracts to get its electricity are supporting the firm's survival.

The company's financial results were released shortly after the Nuclear Regulation Authority acknowledged that reactor 2 at Japan Atomic Power's Tsuruga plant sits above an active fault — a situation that forecloses on the unit's ever being restarted.
