| Title | Safety Injection Actuation Signal While Shutdown |
| Event Description | The following information was provided by the licensee via email:
With Unit 2 in Mode 5 and cooling down for a scheduled maintenance outage, Operations was bypassing safety injection and safety injection bypass sensor modules per procedure. Due to a human performance issue, a safety injection actuation signal was generated. All equipment operated as expected. Operations has reset the safety injection actuation signal and restored the equipment to its required condition. Unit 1 was at 100 percent power and unaffected by this issue. The NRC Resident Inspector will be notified. |
