GROUP III PRIMARY CONTAINMENT ISOLATION
"Received a group III PCIS isolation signal affecting RWCU and the recirculation sample valves while pressurizing RWCU following a RWCU system outage. This event resulted in containment isolation signal affecting valves in multiple systems. Licensee is performing an investigation as to the cause of this event."
The Licensee has notified the NRC Resident.

GROUP 3A CONTAINMENT ISOLATION AT DUANE ARNOLD
"While operating in Mode 1, a fuel pool exhaust radiation monitor spiked, resulting in a Group 3A Primary Containment Isolation System (PCIS) actuation. Radiation levels in the area of the monitor were normal and the actuation was considered invalid. The "A" train of the Standby Gas Treatment System (SBGT) auto-started and the Group 3A isolation functioned as designed. The isolation was reset 14 minutes after the trip."
The NRC Resident Inspector was notified.
