| 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."  |
|                                                                              |
| Operations will inform the DOE site representative and has informed the NRC  |
| resident inspector.                                                          |
