Trespasser removed from Diablo Canyon nuclear property

Pacific Gas and Electric’s (PG&E) Diablo Canyon nuclear plant in California briefly declared an “unusual event” at 2:43 p.m. on Jan. 14, due to a trespasser on PG&E property near the nuclear station.

“A security condition that does not involve a hostile action was reported by the Diablo Canyon security watch commander,” according to the “event report” filed with the Nuclear Regulatory Commission (NRC).

After receiving a call about a trespasser near the plant, deputies from the San Luis Obispo County Sheriff’s Office responded to the scene. “Deputies detained the individual on the Point Buchon Trail about a half mile from the trailhead. The male subject was contacted and identified and was released without further action,” the Sheriff’s Department said in a news release.

The report to NRC said that Diablo Canyon declared an unusual event, due to an “unauthorized person in the Owner Controlled Area,” according to the NRC report.

Diablo Canyon remained at 100% power for the duration of the event, the company noted.

Diablo Canyon Power Plant is a nuclear power facility owned and operated by PG&E. Its two units together produce approximately 2,300 net MW of carbon-free power. It provides nearly 10 percent of all electricity generated in California.
