| REACTOR MANUALLY TRIPPED DUE TO INDICATION OF A STEAM GENERATOR TUBE RUPTURE |
| ON STEAM GENERATOR # 24. |
| |
| The licensee was at 99% power when they received indication of a steam |
| generator tube rupture on steam generator #24. The steam generator tube |
| rupture was initially estimated to be approximately 90 gallons per minute. |
| At 1929, the reactor was manually tripped, and all rods fully inserted into |
| the core. The faulted steam generator was isolated. Currently, reactor |
| coolant system pressure is 2243 psig, temperature is 547 �F and pressurizer |
| level is being maintained at 35%. The licensee declared an Alert |
| classification at 1929 per EAL 3.1.2 (large amount of water out of the |
| reactor coolant system). The NRC entered Standby at 2049 EST. |
| |
| The NRC response was deescalated to Monitoring at 2335 EST. |
| |
| The NRC Resident Inspector was notified of this event by the licensee. |

| UNIDENTIFIED LEAKAGE 1.1 GALLONS PER MINUTE |
| |
| "Elevated reading noted on Unit 2 Plant Vent Radiation Monitor (2R41D) |
| concurrent with slowly lowering Volume Control Tank (VCT) level. Plant was |
| operating at 100% reactor power. Investigation by on-shift personnel |
| estimated unidentified RCS leakage at 1.1 gpm. This value exceeds the Tech |
| Spec limit of 1 gpm unidentified (Reference Tech Spec 3.4.7.2). The Unit 2 |
| Reactor Coolant Filter had been replaced on dayshift. Operators isolated |
| the Reactor Coolant Filter at 2010 and the leakage appears to be stopped. |
| This report is being made for RCS leakage outside containment which may |
| result in exceeding GDC-19 criteria for Control Room habitability." |
| |
| The leak appears to have started at 1638 EST and was stopped at 2010 EST. |
| The volume that was lost is estimated at 160 gallons, the leak was through a |
| hard pipe directly to a radiation waste tank. |
| |
| The licensee notified the NRC Resident Inspector. |
| |
| * * * RETRACTION ON 02/16/00 AT 1647ET BY S. SAUER TAKEN BY MACKINNON * * * |
| |
| Further review of the above event report for reactor coolant leakage outside |
| containment, which may have resulted in exceeding GDC-19 criteria for |
| control room habitability has identified that this leakage flow path is not |
| part of the post accident recirculation flow path in communication with the |
| containment sump. Leakage from systems that are isolated from the |
| recirculation flow path or that can be isolated from it, without degrading |
| the ability to recirculate the reactor coolant system are not included in |
| leakage requirement of the USFAR. |
| R1DO (F. Costello) notified. |
| |
| The NRC Resident inspector was notified of this event retraction by the |
| licensee. |

| FLAWED WELD DISCOVERED DURING PLANT OUTAGE |
| |
| "At 2058 CST on 2/15/2000, a flawed weld was identified on an instrument |
| connection to the Reactor Coolant System Loop 'A' Hot Leg Piping. The |
| subject flaw was identified by Non-Destructive Examination (NDE) at the |
| connection of Level Instrumentation to the RCS Hot Leg Piping. |
| |
| "Unit 1 was taken offline at 0010 on 2/5/2000 for scheduled maintenance. |
| Boron buildup was identified on 2/15/00 at the subject connection while the |
| plant was at cold shutdown condition. The accumulated boron indicates the |
| leakage through the weld flaw is classified as very small weepage. The |
| unidentified RCS leakrate prior to thc scheduled outage was 0.093 GPM. No |
| unexplainable changes in RCS leakrate exist for cycle 16 operation. Due to |
| the physical location of the connection, major scaffolding was required to |
| access the area. At 2058 on 2/15/2000, NDE was complete identifying the |
| reportable condition. Further investigation by Plant Staff is in-progress to |
| characterize the flaw morphology and cause. |
| |
| "This report is being performed to comply with the requirements of |
| 10CFR50.72(b)(2)(i)." |

| TECHNICAL SPECIFICATION REQUIRED SHUTDOWN DUE TO AN UNISOLABLE REACTOR |
| COOLANT PRESSURE BOUNDARY LEAKAGE. |
| |
| At 1305 EST on 02/16/00 a small leak ("weeping steam") was discovered in the |
| reactor coolant system pressure boundary on a 1.5 inch (ID) post accident |
| sampling system line. The leak is estimated to be 0.03 gpm based on |
| historical trending of the reactor building normal sump. The leak was |
| discovered during a reactor building entry to investigate reactor coolant |
| pump seal indications. |
| |
| At 1352 EST on 02/16/00 shutdown was commenced. Unit 1 must be in Mode 3 |
| (Hot Standby) by 02/17/00 at 0105 EST and in Mode 5 (Cold Shutdown) by |
| 02/18/00 at 0105 EST per Technical Specification 3.4.13, "Reactor Coolant |
| Operational Leakage." |
| |
| The post accident sampling line connects to the coolant cold leg piping |
| between the "B" once through steam generator and the suction side of reactor |
| coolant pump "1B2". The leak is coming from the area of a 90 degree elbow |
| where the sampling line passes near the containment floor. |
| |
| All emergency core cooling systems and the Keowee system are fully operable. |
| The electrical grid is also stable. |
| |
| The NRC Resident Inspector was notified of this event by the licensee. |

| UNINTENDED SITE IRRADIATED |
| |
| While performing high dose rate (HDR) endobronchial brachytherapy, it was |
| discovered that unintended sites in a patient had been irradiated. The |
| licensee uses a Nulceatron Micro Selection HDR #31024, controlled by an IBM |
| G50 computer. It was discovered that after the dwell time was entered into |
| the computer, if the enter key is pushed twice instead of once, the distance |
| that the source moves is increased by 100% without warning the operator that |
| the distance had changed. (If the source is supposed move 4 centimeters and |
| you push the enter key twice that source will move 8 centimeters). A patient |
| received three unintended site radiation treatments to his bronchial tube |
| before the problem was discovered. An NRC Region 3 Inspector was at the |
| facility when this incident occurred. |
