| COMMERCIAL IRRADIATOR FACILITY REPORT REGARDING A SOURCE HANG UP             |
|                                                                              |
| Sterigenics is a panoramic, wet-source storage, commercial, irradiator       |
| facility.  At approximately midnight on 10/02/01, a 2.6-megacurie cobalt-60  |
| source got stuck in the unshielded position for approximately 1 hour.        |
| Because the source got stuck on the way down, the licensee lifted the source |
| rack, freed it, and successfully returned it to the shielded position.  The  |
| licensee is still investigating the cause of this event but stated that      |
| there were no obvious reasons at this time.  There were no personnel         |
| radiation exposures or injuries as a result of this event, and there was no  |
| source leakage.                                                              |

| The following text is portion of a facsimile received from Sorrento          |
| Electronics:                                                                 |

| "The information following is in accordance with the reporting requirements  |
| of 10 CFR 21.21(d)(4):"                                                      |
|                                                                              |
| "ii)  Identification of the basic component which contains the defect:  The  |
| basic component which contains the defect is software version 16.0 and       |
| higher of the microprocessor based radiation monitor, RM-2000, with the      |
| 'SAVE MASTER DATABASE' function, where the master database has been restored |
| at least once."                                                              |
|                                                                              |
| "iii)  Identification of the firm supplying the basic component:  Sorrento   |
| Electronics, Inc. [...]"                                                     |
|                                                                              |
| "iv)  Nature of the defect and the safety hazard which is created by the     |
| defect:  The defect was noted at Sorrento Electronics following a power up   |
| on a RM-2000 skid, where the detectors had been detached while the monitor   |
| was powered down.  When the monitor was powered up, the channels associated  |
| with the detectors continued to indicate a green operate status rather than  |
| indicating a NO PULSES operate failure condition.  Further interrogation of  |
| the database revealed the monitor was not responding to taking the channel   |
| in and out of service or to changing the alarm status.  The monitor showed a |
| constant radiation on the channel display.  The affected channels would not  |
| return to a normal operating condition until the detector was reconnected."  |
|                                                                              |
| "This failure will cause the RM-2000 to not process the following tasks      |
| associated with the affected channel:                                        |
| 1. Temperature correction                                                    |

| 4.  Display checksource value                                                |

| 6.  Background subtract                                                      |
| 7.  Pressure correction                                                      |
| 8.  Limit to minimum value                                                   |
| 9.  Display current count rate                                               |
| 10.  Limit to maximum value                                                  |
| 11.  Perform checksource                                                     |

| 13.  Check alarms                                                            |
| 14.  Reset alarms after power failure"                                       |
|                                                                              |
| "v)  Date on which the information was obtained:  The information was noted  |
| on software discrepancy notice, (SDN 545), on August 14, 2001, for review of |
| possible 10 CFR [Part] 21 implications.  Evaluation by [Sorrento             |
| Electronics'] engineering of the problem for 10 CFR [Part] 21 applicability  |
| was immediately begun.  The evaluation was completed and declared reportable |
| on October 1, 2001."                                                         |

| "vi)  The number and location of the components subject to the regulations   |
| per 10 CFR [Part] 21:  The following safety-related equipment is affected:   |

| "vii)  Name of the implementing organization and time frame for implementing |
| the corrective action:  The responsibility for the implementing the          |
| corrective action has been delegated to [...] RMS Engineering.  Sorrento     |
| Electronics will make the individual purchasers aware of this possible       |
| problem.  Further, the RM-2000 operating code will be revised to correct the |
| deficiency.  The new corrected version of the RM-2000 code will be available |
| to customers after November 1, 2001."                                        |
|                                                                              |
| "viii)  Advise related to the defect that will be given to the purchasers:   |
| While this defect is not likely to occur during normal operation at a        |
| nuclear power plant, it is possible.  Therefore, Sorrento Electronics will   |
| advise the affected purchasers via a Quality Bulletin of the following       |
| interim test procedure to verify operability of the affected RM-2000:"       |
|                                                                              |
| "There are two methods to verify that a RM-2000 has not failed after a power |
| fail sequence.  First, if the radiation value being displayed is changing,   |
| the monitor is operating correctly.  Second, if the radiation value is not   |
| changing, then the user should remove the monitor from operation by taking a |
| channel out of service by database manipulation.  If the channel goes into a |
| operate fail condition, the RM-2000 is working correctly and the channel can |
| be returned to service.  If the monitor does not go into an operate fail     |
| condition, the monitor has failed and is not receiving any pulses from the   |
| associated detector."                                                        |

| "General Electric (GE) report titled, 'Impact of Steam Carryover Fraction on |
| Process Computer Heat Balance Calculation, September 2001,' documents a      |
| non-conservative constant for moisture carryover fraction in the equation    |
| used to calculate plant heat balance.  The report states that a number of    |
| later model GE BWR plants report carryover fractions of less than 0.003%.    |
| Currently, Columbia Generating Station uses 0.1% for the carryover term in   |
| the calculation as directed by the GE design specifications.  Use of the     |
| 0.1% term in the heat balance calculation may have resulted in Columbia      |
| Generating Station exceeding the maximum core thermal power value of 3486    |
| MWt specified in license condition 2.C(1) by approximately 2.83 MWt or 0.08% |
| Rated Thermal Power.  As a compensatory measure until this issue is          |
| resolved, Columbia Generating Station will adopt a conservative value of     |
| 0.0% for the moisture carryover term in the plant heat balance calculation.  |
| Consequently, the Plant Process Computer eight hour average core thermal     |
| power is currently being administratively controlled at less than or equal   |
| to 3482 MWt."                                                                |
