Soviet officials in charge of cleaning up the Chernobyl nuclear-disaster site plan to restart two of the power plant’s four reactors in the fall, a Communist Party official said. Alexander Domanyuk, party official in the nearby town of Pripyat, said on Soviet television that the commission investigating the April 26 accident in the plant’s No. 4 reactor wants to get reactors No. 1 and No. 2 going in October.
