The Public Service Enterprise Group (NYSE:PSEG) Hope Creek 1 nuclear facility in New Jersey was still listed at zero power generation by the Nuclear Regulatory Commission (NRC) early Sept. 30 following a problem with reactor circulation pumps.
The nuclear generator was forced offline Sept. 28 after 8 p.m. ET. The reactor scrammed following a trip of both reactor recirculation pumps, according to an event report filed with NRC.
“All control rods fully inserted into the core. All safety systems responded as designed and expected. There was no radiological release. The unit is stable in Mode 3 with decay heat being removed via the turbine bypass valves rejecting steam to the main condenser. Normal feed water level control is providing makeup to the reactor vessel,” according to the report filed with NRC.
The cause of the pumps tripping continues to be investigated. It is not known when the unit will return to service, a PSEG spokesperson said.
The company’s neighboring Salem Generating Station was not impacted with both its units operating at full power. Both Salem units are pressurized water reactors and each has a generating capacity of more than 1,100 MW.
Hope Creek is a single-unit boiling water reactor (BWR) located in Salem County, N.J. The facility, which went online in 1986, has a generating capacity of more than 1,100 MW.
PSEG is currently pursuing an early site permit through NRC, opening the door to potential development of a new nuclear unit alongside Salem and Hope Creek.
