sReactor to Close

KIEV () -- Ukraine vowed Monday to shut down one of two reactors still producing electricity at the Chernobyl nuclear plant Nov. 30, falling in line with a timetable agreed with Western donors.

"On Nov. 30 Reactor No. 1 will be stopped completely," Environment and Nuclear Safety Minister Yury Kostenko told a news conference.

Ukrainian officials had promised to shut down the reactor in November, but Kostenko said two weeks ago that stopping it as planned could make the station, scene of the world's worst nuclear accident, more prone to problems.

The fourth reactor at the plant exploded in 1986, sending a radioactive cloud across much of Europe. It is now encased in a cracking concrete "sarcophagus," while a second reactor was closed after a fire in 1991.
