The result shows that if the cooling system of the spent fuel storage pool can be retrieved in 19 hours, the natural circulation cooling ability is sufficient to prevent radioactivity release.

计算结果表明。恰希玛核电厂乏燃料池冷却系统失效后， 只要在19 个小时内修复冷却系统， 不会出现大量放射性物质外泄。

The IAEA statement was released hours after Tepco temporarily shut down the cooling system in the second unit's spent fuel pool following the discovery of dead rodents near a transformer.

The system cooling water which contained spent - but still highly radioactive - nuclear fuel rods failed and it took engineers some 30 hours to repair the damage.

In early April, the cooling system at one of the pools containing spent - but highly radioactive - fuel rods in reactor number three broke down for about three hours.
