PLYMOUTH — Federal regulators found two violations related to cybersecurity at Pilgrim Nuclear Power Station during an inspection last month.
And although details are scarce, in both instances staff performance at the plant, which is owned and operated by Entergy Corp., again fell short.
A Nuclear Regulatory Commission official wrote to Entergy on Tuesday, saying that in the first infraction, the company “did not take effective corrective actions to resolve and correct a previous NRC-identified violation.”
The second violation occurred “because Entergy did not conduct an adequate evaluation of a security issue,” wrote Glenn Dentel, chief of Engineering Branch 2 of the Division of Reactor Safety.
NRC spokesman Neil Sheehan said the nature of the cybersecurity-related violations, along with actions taken to correct them, “are considered sensitive information” and therefore not publicly disclosed.
“We can say that Entergy implemented compensatory measures to address any security-related vulnerabilities associated with these violations as soon as the issues were identified,” Sheehan said.
One of the violations, however, had been identified once before by the NRC, according to Dentel’s letter.
