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 plant's 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. Following Sunday's shutdown, a PSEG official said an excessive amount of moisture can damage the turbine.

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.
