TSURUGA, Fukui (Kyodo) -- The central control room for the Nos. 3 and 4 reactors at the Oi power plant in Fukui Prefecture registered two alarms indicating trouble with electric power cables between late Saturday and early Sunday, but no glitches were found, according to the plant's operator, Kansai Electric Power Co.

The utility said the alarm system error is believed to have been caused as a radio signal, which monitors the connection conditions of the cables, was temporarily interrupted due to an unstable atmosphere.

Kansai Electric is now preparing to reactivate the two reactors following the government's decision to resume them. The latest trouble will not affect the preparation works, it said.
