Tokyo Electric Power Company has been forced to change its strategy at the
quake-hit Fukushima Daiichi nuclear power plant due to high radiation levels
at the site.
The plant's nuclear reactors 1 through 4 have all lost their cooling
capabilities as both external and backup power supplies failed after the
quake and tsunami.
TEPCO has been working to restore the external power supply while trying to
cool the reactors and spent fuel storage pools by using pump trucks to
secure water levels.
However, 3 workers were exposed to highly radioactive water in the basement
of the turbine building of the No.3 reactor on Thursday. The radiation level
there was 200 millisieverts per hour at one time.
This led to a change in plans. In an effort to continually cool the reactors
, TEPCO has started to pump fresh water instead of seawater into the No. 1
and No. 3 reactors on Friday.
With this strategy in mind, the company first intended to use the reactors'
water pumps. But they were forced to use pump trucks instead from a distance
, after high radiation levels were detected near the reactors' pumps.
The company plans to switch on lights in the No.2 reactor's control room on
Saturday through an external power supply. Meanwhile, they will also
continue to use trucks to pump fresh water into the reactor.

我记得前几天新闻报道1-6已经全部恢复电力供应了
现在1-4怎么又废了? | x****u
