A reactor at the San Onofre Nuclear Generating Station was shut down because of a problem with the electrical supply for a motor that operates control rods, a utility spokesman said Saturday. Plant operators noticed the problem at noon Friday and gradually reduced the power level in the unit until it was shut down at 9:28 p.m., said Southern California Edison spokesman Dave Barron. The utility expected to have the 1,100-megawatt unit running again by Monday morning. "It's not a serious problem. We'll probably get it fixed by the end of the weekend," Barron said. Even if the problem continues into the week, there is no risk of a power shortage in Southern California, he said. The plant on the coast between Los Angeles and San Diego has three reactors. One has been closed down for some time, and the third is operating at normal levels, he said.
