| 24-HOUR REPORT INVOLVING A VALID ACTUATION OF A "Q" CLASS SAFETY SYSTEM      |
|                                                                              |
| "At 0710 hours on 04/16/01, Autoclave #4 in the X-344 UF6 Sampling Facility  |
| had an 'AUTOCLAVE HI HI PRESSURE' alarm activation. This alarm initiates an  |
| 'Autoclave Shell High Pressure Containment Shutdown', which causes the       |
| autoclave containment isolation valves ('Q' components) to actuate. The      |
| containment isolation valves closed, as designed. The initiating devices for |
| this alarm are redundant pressure switches with a TSR set point of 8.0 psig. |
| Autoclave #4 was in TSR Operational Mode IV (Feeding, Transfer, or Sampling) |
| at the time of the alarm activation. Operations personnel immediately        |
| responded to the alarm in accordance with the approved Alarm Response        |
| Procedures. Autoclave #4 was placed in TSR mode VII (Shutdown) by operations |
| personnel and declared inoperable by the Plant Shift Superintendent.         |
|                                                                              |
| "Instrument Maintenance was requested to perform 'as-founds' on the          |
| 'Autoclave Pressure Loop Instrumentation'. The results of this data          |
| indicated that the instrumentation associated with the 'Autoclave Internal   |
| Pressure Loop' was found to be within acceptable 'as-found' tolerance. Based |
| on these results, this event is being reported as a valid safety system      |
| actuation, a 24-hour NRC event. An Engineering Evaluation has been requested |
| to investigate the circumstances surrounding this safety system actuation."  |

| "While in Mode Undefined (core offloaded), Salem Unit 1 received a           |
| Containment Ventilation Isolation signal due to elevated count rate on       |
| 1R11A, the Containment Particulate Radiation Monitor. The 1R11A setpoint is  |
| set two times background in accordance with Tech Spec 3.3.3.1 for Mode 6.    |
| Background count rate prior to the CVI was 2100 cpm (counts per minute). The |
| alarm setpoint was 2980 cpm.                                                 |
|                                                                              |
| "The observed count rate when the actuation occurred was 3300 cpm.           |
| Maintenance activities in progress included the breech of 14SJ43, Cold Leg   |
| Injection Check Valve. Elevated airborne activity was expected due to this   |
| evolution and had been discussed by Control Room personnel. When 1R11A       |
| exceeded its setpoint, all containment ventilation isolation valves closed   |
| as designed. This actuation has not impacted the Unit 1 outage.              |
