3 nuclear accidents in us today and now a this becomes known... coincidence ??? And dont for a second believe they are telling the full extent of what has happened... they never tell the truth.. Pilgrim Nuclear Power Station shut down Tuesday, Dec. 3, due to a steam leak on a valve, which provides sealing steam to the main turbine. The leak, which is not nuclear safety related, required the reactor be shut down to make repairs according to the Nuclear Regulatory Commission. NRC Resident Inspectors monitored the shutdown and will observe the repair work. During a tabletop emergency drill Tuesday, a problem was found in the plants internal conferencing bridge lines. Additional communication lines have been established while the computer server problem is being resolved. The Hope Creek nuclear plant in Salem County was taken offline Sunday after a high level of moisture was found in the steam that spins the plants turbine. The incident happened at 6:13 a.m., and the Nuclear Regulatory Commission said all safety systems responded as designed. The NRC said no radiation was released at the reactor in Lower Alloways Creek Township, and no one was injured. Public Service Enterprise Group owns and operates the nuclear plant, along with neighboring Salem 1 and 2 reactors. Hope Creek is equipped with a reactor protection system that can automatically shut down the reactor if certain parameters are exceeded, said Neil Sheehan, an NRC spokesman. On Sunday, the system shut down the main turbine then the reactor. PSEG Nuclear spokesman Joe Delmar told the South Jersey Times high moisture can damage the turbine. A PSEG review determined that the failure of a control valve was responsible for the problem, Sheehan said. In late August, Salem 1 nuclear power plant was manually shut down following a leak of slightly radioactive water inside the containment building. Operators at Nine Mile Point Unit 2 nuclear reactor shut down the plant this morning after pumps that circulate water through the reactor shut off while being shifted to a lower speed. Unit 2, which produces up to 1,360 megawatts, shut down at 9:04 a.m. Constellation Energy Nuclear Group, which operates the plant, did not predict when it would return to operation. The adjacent 620-megawatt Unit 1 reactor was not affected and remains at 100 percent power, said Jill Lyon, speaking for CENG, a unit of Exelon Corp. Nine Mile 2 had been operating at about 78 percent power since Nov. 26 as crews made repairs to the feedwater heating system, Lyon said. Today, as part of that work, operators reduced power further to facilitate the repairs. As operators powered the unit down, they shifted the recirculation pumps to a lower speed. During the shift, both pumps shut down, which according to procedure requires an immediate manual shutdown of the reactor, Lyon said. The pumps were subsequently restarted and are operating, but plant officials are still investigating what caused them to fail and what repairs are needed, Lyon said. Once repairs to the equipment are complete, the unit will begin a return to service, she said. grist.org/news/nuclear-plant-spills-radiation-into-lake-michigan/ hisz.rsoe.hu/alertmap/index2.php
