nuclear plant regulator said Wednesday the top priority now is to pump water
into the No. 3 and No. 4 reactors in the quake-stricken plants in northern
Japan
to
keep spent nuclear fuel stored in them from emitting radiation.
Water inside the two troubled reactors in the Dai-ichi Fukushima plant are
likely boiling, as indicated by vapor-like white smoke coming out of the No. 3
reactor, an official at the Nuclear and Industrial Safety Agency said at a
press briefing.
"It is our top priority to address problems concerning the water pools for
spent fuel," he said.
Conditions of the spent-fuel pools are luring increasing attention as

worst nuclear-plant crisis continues. If used nuclear fuel rods---which tend to
grow hotter on their own without coolant water--were left heating up, they
could eventually melt and spat out deadly radiation into the air, according to
officials from the agency.
Tokyo Electric Power Co., the operator of the
Fukushima
complex, may consider using a helicopter to drop water on the No. 3 reactor if
conditions are good enough to safely carry out such operations, the first
official said.
He added that the No. 3 reactor's pressure containment vessel, one of the key
layers surrounding the fuel room, is unlikely to have suffered damage, as a
sharp rise in radiation levels recorded around noon near the complex was short
lived.
