Operators returned Monticello Nuclear Generating Plant to full power Monday, Aug. 20, following a shutdown that was needed to make repairs. The 600-megawatt Monticello plant was returned to full power at 10:45 a.m. Aug. 20, after workers repaired a gasket on a pipe flange.
Prairie Island Nuclear Generating Plant Unit 1 is back on line and continues to move toward full power, following an unrelated shut down last week. At Prairie Island, operators placed the 550-megawatt Unit 1 in service after workers repaired minor exhaust leaks on the diesel generators.
When operators shut the units down Tuesday, Aug. 14, all plant safety systems functioned as designed. Neither situation posed any danger to the public or plant workers. Prairie Island Unit 2, also a 550-megawatt unit, was not affected by the Unit 1 shutdown and continued to operate at full power.
