| UNPLANNED REACTOR PROTECTION SYSTEM (RPS) SYSTEM/SAFETY SYSTEM ACTUATIONS |
| WHILE CRITICAL |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "[The unit] received [an] isolation of the [transverse incore probe (TIP)] |
| purge system and the offgas system during [an] electrical transient on the |
| 230kV distribution system. [The licensee believes] the isolations were |
| caused by the voltage fluctuations felt in the plant from the grid. Since |
| the TIP purge isolation is processed through [the reactor protection system |
| (RPS)] and offgas from the offgas [radiation] monitors, this falls under |
| actuation of a safety system while critical." |
| |
| "[The licensee] reset isolations and restored systems to normal." |
| |
| The licensee stated that the isolation signals that were processed did not |
| show up on any alarms. Alarms were received but nothing specific to |
| indicate the isolations. This may have been due to voltage |
| fluctuations/losses as a result of power/instrument panels that transferred |
| to their alternate power supplies. The voltage fluctuations on the in-house |
| 4160V buses were attributed to the electrical transient on the 230kV |
| distribution system. |
| |
| There was severe weather in the area at the time of this event. As a |
| result, one of two 230kV outgoing power lines and both 34.5kV feed lines |
| were lost. All of these lines have since been returned to service. The |
| licensee stated that offsite power was never lost because one 230kV line |
| remained available to backfeed/supply the 34.5kV buses. |
| |
| The licensee notified the NRC resident inspector. |
| |
| * * * RETRACTED AT 1840 EDT ON 8/16/2001 BY JERE FREEMAN TO FANGIE JONES * * |
| * |
| |
| The licensee, after review of the event, determined that the actuation of a |
| single component due to a power panel transfer on a voltage transient did |
| not meet the requirement of an actuation of the containment isolation system |
| for reportability. Per NUREG 1022 Rev 2, this event was not reportable and |
| is retracted. |
| |
| The licensee notified the NRC Resident Inspector. The R1DO (William Ruland) |
| has been notified. |

| 24-HOUR NRC BULLETIN 91-01 REPORT |
| |
| The licensee has notified the NRC Resident Inspector and the DOE |
| representative. |
| |
| The following text is a portion of a facsimile received from Portsmouth |
| personnel: |
| |
| During a walk through of the X-705 Decontamination Facility a hole was |
| discovered on the top of the Calciner glove box. The hole could have allowed |
| uranium bearing solution to accumulate in the bottom of the glove box [in] |
| the unlikely event of a leak. This is in violation of the analysis of |
| NCSA-705_024.E02 "Calciner Solution Recovery" which specifically evaluates |
| this event. |
| |
| The PSS entered an anomalous condition. Tape was placed over the hole on the |
| top of the Calciner glove box. The PSS exited the anomalous condition. |
| |
| This event is reportable per NRC BL 91-01 as a loss of one control of the |
| double contingency principle. |
| |
| SAFETY SIGNIFICANCE OF EVENTS: low |
| |
| There was no leak of uranium bearing material in the vicinity of the |
| Calciner glove box. Also, the opening on the glove box is very small. This |
| would require a significant amount of time for the solution to accumulate in |
| the glove [box] had a leak occurred at that exact location. |
| |
| POTENTIAL CRITICALITY PATHWAYS INVOLVED (BRIEF SCENARIO[S] OF HOW |
| CRITICALITY COULD |
| OCCUR): |
| |
| For a criticality to occur, the following events would be required: The |
| recovery system would have to be operating and processing uranium bearing |
| liquid with a high concentration of uranium. Then the leak in this system |
| must occur such that solution sprays onto the glove box. The liquid would |
| then have to flow through the small opening on the top of the glove box and |
| accumulate to a depth of >1.5 inches. |
| |
| CONTROLLED PARAMETERS (MASS, MODERATION, GEOMETRY, CONCENTRATION, ETC.): |
| volume, geometry |
| |
| The unlikely event supporting double contingency credits the integrity of |
| the glove box for preventing solution from collecting in an unsafe |
| geometry/volume. The hole on the top of the glove box could potentially |
| allow solution to enter the glove box. |
| |
| ESTIMATED AMOUNT, ENRICHMENT, FORM OF LICENSED MATERIAL (INCLUDE PROCESS |
| LIMIT AND % WORST CASE OF CRITICAL MASS): |
| |
| No uranium material was involved in this event. |
| |
| NUCLEAR CRITICALITY SAFETY CONTROL(S) OR CONTROL SYSTEM(S) AND DESCRIPTION |
| OF THE FAILURES OR DEFICIENCIES: |
| |
| The hole could have allowed uranium bearing solution to accumulate in the |
| bottom of the glove box in the unlikely event of a leak. This is in |
| violation of the analysis of NCSA-705_024.E02 "Calciner Solution Recovery" |
| which specifically evaluates this event. The presence of the opening |
| undermines the basis of an unlikely event credited for double contingency. |
| |
| CORRECTIVE ACTIONS TO RESTORE SAFETY SYSTEM AND WHEN EACH WAS IMPLEMENTED: |
| |
| Tape was [placed] on the hole on top of the glove box. |

| OFFSITE NOTIFICATION DUE TO OIL SPILL AT ASSOCIATED HYDRO UNIT |
| |
| The licensee was performing work on the pier at the Keowee Hydro Intake |
| structure when about 1 gallon of Mobil EAL 224H (biodegradable) oil spilled |
| into Lake Keowee. A boom had previously been installed and contained the |
| oil in a 50 foot by 50 foot area. The spill was a result of a hydraulic |
| hose leak. The clean-up was nearly complete at the time of the report. |
| There was no effect on plant operations or any safety significance. |
| |
| The licensee notified the National Response Center, the South Carolina |
| Department of Health and Environmental Control, and the NRC Resident |
| Inspector. |

| AGREEMENT STATE REPORT - DAMAGED TROXLER GAUGE |
| |
| "At approximately 1:40 PM on August 14, 2001 an unidentified person in a |
| private automobile ran over a Troxler nuclear density gauge while this gauge |
| was being used by a trained technician at a work site southwest Denver. The |
| technician narrowly escaped being stuck by the vehicle, but the vehicle did |
| strike the gauge. The exterior casing of the gauge was damaged and broken |
| into numerous pieces as a result of the collision. However the sealed source |
| and shielding assembly remained intact. Following the incident the source |
| was able to be retracted into the shielding and the shutter closed." |
| |
| Denver Police were notified immediately following the incident. |
| |
| The site and the gauge with the sealed source were surveyed and no leakage |
| was found. |
| |
| The Troxler gauge involved is a model 4640B (serial number 841) containing a |
| single, 8-millicurie, Cs-137, sealed source (serial number 50-7987). |
| |
| The gauge will be shipped back to Troxler. |

| LOSS OF EMERGENCY SIREN REMOTE ACTUATION CAPABILITY |
| |
| "Omni phone system was lost resulting in a loss of Emergency Siren remote |
| actuation control. Power was lost 8/16/01 22:25 EDT and restored 8/16/01 |
| 23:55 EDT. Per reportability manual ID# E-02 and Event# SAF 1.10, loss of |
| assessment capability is reportable after 8 hours, but loss of greater than |
| 25% of the sirens for more than one hour constitutes immediate |
| notification. |
| |
| "The omni phone system was lost due to the associated battery voltage |
| becoming too low to support system operation. This was caused by a |
| temporary battery charger installed in place of the normal charger (due to a |
| failed transformer) not maintaining the battery adequately charged. |
| Immediate omni system recovery was effected using available AC power from an |
