Oyster Creek Generating Station has returned to service after a 42-day refueling and maintenance outage, which included fixing some “indications” and a pinhole leak.
The power generator went offline Oct. 22 for a planned refueling outage and after all the fixes was operating at 22 percent earlier this week, according to the Nuclear Regulatory Commission (NRC).
Since that outage, the NRC reported the discovery of “indications,” or precursors to cracks, in the reactor nozzle and a pinhole leak in the reactor vessel head cooling system.
Workers at the facility fixed the issues and received the green light to start up, said NRC spokesman Neil Sheehan said.
“NRC metallurgical specialists reviewed the company’s evaluation of the flaws and its repair plans and work. We were satisfied that the repairs were thorough and consistent with ASME (American Society of Mechanical Engineers) Code,” he said.
Oyster Creek is the oldest operating nuclear plant in the country and provides enough around-the-clock electricity for 600,000 New Jersey homes and began commercial operations in 1969.
