Tokyo, Japan — ESI-AFRICA.COM — 30 May 2011 – The system to cool the nuclear reactor and fuel pool has stopped at the No. 5 unit of the crippled Fukushima Daiichi power plant in northeastern Japan, but there appears to be no danger of the unit heating up beyond safety levels.

Revealing this in a statement here, a spokesman for plant operator Tokyo Electric Power said the operator had started work to repair the cooling facility, and hoped to restore the system within a matter of hours. The official said the breakdown of the cooling systems would not lead to a rapid rise in temperatures at the reactor and spent fuel pool.

The Fukushima Daiichi plant’s No. 1 to 4 reactors were severely damaged after the March 11 earthquake and tsunami, while damages at the No. 5 and No. 6 reactors were less severe.
