| POTENTIAL MISADMINISTRATION INVOLVING DISLODGED BRACHYTHERAPY SOURCE |
| |
| AT APPROXIMATELY 0915EST AN ELDERLY FEMALE PATIENT NOTIFIED HOSPITAL STAFF |
| THAT A BRACYTHERAPY SOURCE (Cs-137 - 21.8 MILLIGRAM RADIUM EQUIVALENT) HAD |
| BECOME DISLODGED. HOSPITAL STAFF CONTACTED THE PHYSICIAN THAT HAD INSERTED |
| THE SOURCE AND WAS INSTRUCTED TO RELOCATE THE APPLICATOR TO THE FOOT OF THE |

| ACTUATION OF TWO UNIT 2 AUXILIARY BUILDING NORMAL RADIATION MONITORS DURING |
| PERFORMANCE OF VENTILATION SYSTEM SURVEILLANCE TESTING |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "At 2230 [CST] during normal Unit 1 [and] 2 [reactor coolant system] |
| sampling, a [high] radiation and [emergency safety feature (ESF)] actuation |
| signal was received on [radiation monitors] 2R-30 and 2R-37 ([auxiliary |
| building] normal exhaust monitors). Normal exhaust was off, and [the |
| auxiliary] building special ventilation system was in operation while |
| performing [surveillance procedure] SP-1172, Monthly Ventilation System |
| Operation. Alarm response procedures were completed for high radiation on |
| 2R-30 [and 2R-]37. [The] duty chemist was informed, the sample was secured, |
| and 2R-30 [and 2R-]37 levels [then] returned normal. At 2255 [CST,] the |
| actuating signals were reset, and all equipment returned to normal." |
| |
| The licensee stated that all systems functioned as required in response to |
| the high radiation and ESF actuation signal. The cause of the ESF signal is |
| under investigation. At the time of this event notification, both units |
| were operating at 100% power. |
| |
| The licensee notified the NRC resident inspector. |
| |
| * * * UPDATE AT 1251 ON 12/30/99 BY DALE JOHNSON TO JOLLIFFE * * * |
| |
| The licensee desires to retract this event because the regulation does not |
| require reporting of an actuation of the Auxiliary Building Special |
| Ventilation System if it was started by an invalid start signal. The |
| licensee determined that the actuation in this instance was initiated by an |
| invalid start signal. |
| |
| The licensee plans to notify the NRC Resident Inspector. |
| |
| The NRC Operations Officer notified the R3DO Bruce Burgess. |

| HPCI INOPERABLE |
| |
| During QCOS 2300-28 'HPCI Turning Gear Logic Functional Test' the HPCI |
| turning gear failed to engage. The test was stopped and HPCI was placed on |
| the turning gear from a normal standby lineup and removed from the turning |
| gear using QCOP 2300-13 'HPCI Turning Gear Operation'. Per analysis the |
| HPCI turbine must be able to be remotely placed on the turning gear. Since |
| HPCI failed to go on gear during the logic test it was declared inoperable |
| at 0420. A 14 day LCO was centered per Tech Spec 3.5.A action 3. |

| Feedwater Heater. During withdrawal of Control Bank B to 85 steps, Control |
| Bank B rod B6 became misaligned from its bank by Digital Rod position |
| indication System (DRPI) indication and the demand step counters. The Rod |

| - Unit 1 and 2 valves have the potential to experience pressure locking |
| under post-LOCA conditions - |
| |
| Motor operated valves ICM-305 and ICM-306, for both units, have been |
| identified as having the potential to experience pressure locking under |
| post-LOCA conditions. These valves are the ECCS suction valves from the |
| recirculation sump that are opened to supply water to the Residual Heat |
| Removal (RHR) pump suction, which in turn supplies flow to the suction of |
| the safety injection and charging pumps. Calculations performed during a |
| review of Generic Letter 95-07 determined that the valve operators are |
| potentially incapable of opening the valves under pressure locking |
| conditions, which result from the post LOCA temperature rise. |
| |
| Additionally, Units 1 and 2 IMO-330 and IMO-331, the RHR to upper |
| containment spray shutoff valves, have been determined to experience the |
| same post-LOCA pressure locking problem. These valves provide isolation of |
| RHR flow to the upper containment spray headers, and are opened during the |
| recirculation phase of an accident if upper spray is needed. |
| |
| Design changes are being developed to modify the valves to eliminate the |
| potential for pressure locking. |
| |
| The licensee notified the NRC Resident Inspector. |

| UNUSUAL EVENT - MAIN TRANSFORMER FAILURE |
| |
| A main transformer insulator failure led to a catastrophic failure of the |
| main transformer. This in turn led to a turbine trip and reactor scram. |
| The plant response to the transient was normal and the plant is now stable |
| in mode 3. Decay heat is being removed by dumping steam to the main |
| condenser. Reactor vessel water level is being maintained by the condensate |
| and feed systems. Offsite power was maintained throughout the event and no |
| safety related equipment has been damaged. The event occurred at 0111 and |
| the Unusual Event was declared at 0255. The Reactor Recirculation Pump |
| EOC-RPT (End of Cycle Recirc Pump Trip) breakers tripped as expected due to |
| the turbine stop valve and turbine control valve closures. |
| |
| The unusual event was declared because of the potential impact of the |
| failure on other plant components in the vicinity of the transformer. The |
| licensee has notified the resident inspector. |
| |
| * * * UPDATE AT 0431 ON 12/31/99 BY AMTSFIELD, RECEIVED BY WEAVER * * * |
| |
| The unusual event was terminated at 0400. Damage was limited to the main |
| transformer phase 'B' insulator with only ancillary damage to surrounding |
| equipment and no damage to safety related equipment. The licensee has |
| notified state and local governments of the event and a press release will |
| be issued. |
| |
