SAFETY SYSTEM ACTUATION - AUTOCLAVE HIGH CONDENSATE LEVEL ALARM RECEIVED DURING HEATUP
"At 0930 hours, Autoclave (AC) # 2 in the X-344 Facility experienced a Steam Shutdown due to high condensate level alarms (A) and (B) actuating. The AC was in applicable TSR Mode II 'Heating' for 45 minutes when the actuation occurred. This is considered a valid actuation of a 'Q' Safety System. The autoclave was placed in MODE IV 'Shutdown' and declared inoperable by the Plant Shift Superintended (PSS). An investigation is underway to determine the cause of the actuation. No release of radioactive material occurred as a result of the incident. This event is being reported in accordance with UE2-RA-RE1030 Appendix D. J. 2. Safety Equipment Actuation."
