Specifically, 10CFR50.72(b)(2)(iv)(B) for actuation of the reactor protection system (RPS) when the reactor is critical, and 10CFR50.72(b)(3)(iv)(A) for valid actuation of systems listed in paragraph (b)(3)(iv)(B). Various system actuations occurred as a result of the loss of offsite power. </br>The NRC Resident Inspector was notified along with state and local agencies.</br>Notified Reg 1 RDO(Meyer) local agencies.
