The Nuclear Regulatory Commission says Unit 1 of Exelon Nuclear's Limerick Generating Station shut down at 10:15 a.m. Friday. Commission spokesman Neil Sheehan said there were no complications and safety systems responded as expected.
Sheehan says investigators are trying to determine the cause of the latest shutdown, which occurred as operators were doing a test involving the turbine.
The shutdown came less than a day after the plant put the Unit 2 reactor back online following unplanned shutdowns Sunday and Monday.
The Pottstown Mercury says a public community information session is planned Wednesday evening at the plant.
