| CRITICALITY ALARM HORNS AIR PRESSURE FOUND OUT OF SPECIFICATION DURING       |
| SURVEILLANCE                                                                 |

| "At 1330 on 11/2/00, the Plant Shift Superintendent was notified that the    |
| testing of the C-337 and C-337-A Criticality Accident Alarm System (CAAS)    |
| air horn regulators resulted in as found data which is outside of the        |
| optimum air pressure band allowed to insure desired horn sound quality.      |
| Twelve of the twenty-five CAAS horn regulators located in these two areas    |
| were discovered outside the desired pressure band. The effect of this as     |
| found condition is unknown at this time and is being evaluated by            |
| Engineering. This evaluation will require greater than the 24-hour reporting |
| time limit allowed by 10 CFR 76.120.c.2. Due to the uncertainties and the    |
| length of time required to complete the engineering evaluation the condition |
| is being conservatively reported.                                            |
|                                                                              |
| "Reasonable assurance of operability of CAAS horns in these and other        |
| buildings exists based on the successful completion of quarterly and annual  |
| TSR surveillances. In addition, all CAAS horn regulators found outside of    |
| established criteria during this and previous tests on other building CAAS   |
| systems were returned to acceptable values prior to returning the systems to |
| service.                                                                     |

| "This event is reportable under 10 CFR 76.120(c)(2) as an event in which     |
| equipment required by the TSR is disabled or fails to function as designed.  |
|                                                                              |

|                                                                              |
| "On November 2, 2000, the PSS was notified that the testing of the C-337 and |
| C-337A CAAS air horns had resulted in the discovery that the horn air        |
| regulator pressure was outside of the allowed optimum air pressure band used |
| to ensure desired horn sound quality. This condition potentially affected    |
| the audibility of twelve of the twenty-five horns located in the C-337 and   |
| C-337A. The actual affect on the system was unknown at the time and could    |
| not be determined within the 24-hour reporting limit. Thus, the condition    |
| was conservatively reported to the NRC per 10CFR76.120(c)(2).                |
|                                                                              |
| Subsequently, System Engineering issued Engineering Notice EN-C-822-00-035   |
| that transmitted the results of Operability Evaluation OE-C-822-00-005. This |
| documented the results of additional CAAS horn testing at the air regulator  |
| pressure values noted on November 2, 2000 and testing data in other          |
| buildings. The evaluation concluded that although there is an expected       |
| amount of drift or variance in the settings of the air pressure regulators   |
| [for] the CAAS horns, in the as-found condition, could have performed their  |
| intended safety function and pass the audibility criteria described in the   |
| SAR."                                                                        |

| "At 0340 on 11/22/00, the PSS office was notified that a primary condensate  |
| alarm was received on the C-333A position 3 South autoclave Water Inventory  |
| Control System (WICS). The WICS system is required to be operable while      |

| Superintendent. The WICS actuation has been determined to be a valid         |

| The licensee contacted the State of Illinois to request assistance in        |
| locating a 20 mCi Cs-137 source. The source was mounted in an Omart model    |
| SH-F1 holder, and was licensed under a general license. Representatives of   |
| the state surveyed warehouses and other buildings throughout the licensee's  |
| facility and other licensee locations, but were unable to locate the source. |
| The licensee is currently investigating whether the source may have been     |
| sent to a licensee facility in Colorado; however, the source may have been   |
| discarded during renovations to the warehouse in which it had been located.  |
| In this instance, the source may have been deposited in a landfill in        |
| Wisconsin. The state is continuing its investigation of this matter.         |
