World IN BRIEF : EASTERN EUROPE : Aid for Soviet Nuclear Plants

President Bush and leaders of six other major industrial powers are expected to approve a costly program to prevent another Chernobyl-order disaster at Soviet-designed nuclear plants, a newspaper reported. The $9-billion to $11-billion program is likely to be endorsed at the Group of Seven economic summit in Munich, Germany, in July, the New York Times said. The ex-Soviet republics have 16 large graphite reactors of the kind that exploded in Chernobyl in 1986, killing at least 32. The reactors also are used in Bulgaria, Czechoslovakia, Hungary and elsewhere.
