L 'Salem Unit 2 was shut off manually by operators control room at 10:01 Friday, according to Joe Delmar, spokesman for PSEG Nuclear, after a problem with one of the control rods. There was no threat to the health and safety of the public, and no problem with manual switch off, he added. A return to service is not available at this time. The plant was online 430 days in a row, and produces 1,175 megawatts of electricity, "enough power for a million homes. Mr. Delmar also pointed out that, on Friday, the control room operators were conducting the monthly test on the bars control used to control the power of the reactor. During the test, monthly, one of the control rods has abandoned its intended position. In a pressurized water reactor as Salem, the control rods are inserted into the upper part of the fuel elements. There are 193 nuclear fuel elements in the reactor core Salem and 53 control rods. Responding to bad positioning of the control, the control room operators have appropriate actions including the addition of boron in ' water reactor to reduce the level of power and maintain the margin of arrest, as required by the safety specification. Salem Unit 1 and the plant near Hope Creek were not affected and remain at full power. comed ------------------------ ENGLISH VERSION ---------------------- Salem Unit 2 was manually taken offline by control room operators at 10:01 am Friday, according to Functional Joe Delmar, spokesman for PSEG Nuclear, after an issue with one of the control rods. There was no threat to the health and safety of the public, and no issues with the manual shutdown, comed he added. A return to service is not available at this time. The plant Had Been Online comed 430 consecutive days, Delmar said, and it Produces 1175 megawatts of electricity "enough power for a million homes. On Friday morning, Delmar said control room operators were conducting monthly testing on the control comed rods used to control reactor power. During the monthly testing, one of the control rods dropped out of Its expected position, he said. At this time, the expected causes of the control rod is mispositioning Believed to be a blown fuse with them to more detailed investigation under way. In a pressurized water reactor like Salem, the control rods are inserted into the top of the fuel assemblies. There are 193 nuclear fuel assemblies inside the reactor core Salem and 53 control rods. In response to the control rod mispositioning, Delmar said control room operators Took appropriate actions including adding boron to the reactor water level to reduce power and 'maintain shutdown margin as required by NRC technical specifications. Operators Subsequent conservative comed then made the decision to shut the unit down safely, comed he said. Salem Unit 1 and the neighboring Hope Creek plant were not impacted and REMAIN at full power. Salem 2 is one of three reactors operated by PSEG Nuclear at its Artificial Island generating site on here.
