| BOTH CONTROL ROOM EMERGENCY VENTILATION TRAINS INOPERABLE FOR ABOUT 11 |
| HOURS |
| |
| The following text is a portion of a facsimile received from the licensee: |
| |
| "EVENT DESCRIPTION: On 01/14/99 at 1305 [CST,] the Control Room Emergency |
| Ventilation (CREV) train 'B' was placed in service for flow rate testing |
| following scheduled replacement of the charcoal trays. At the time CREV |
| train 'B' was started, CREV train 'A' was the only operable CREV train. |
| When CREV 'B' was started, the CREV primary unit selector switch |
| (0-XSW-31-7214) was placed in the 'B' position. This in conjunction with |
| CREV 'B' in service for testing, rendered CREV 'A' incapable of |
| automatically starting on a valid initiation signal. Thus, both CREV trains |
| were inoperable from 1305 hours on 01/14/99 until 0008 hours on 01/15/99. |
| |
| "REPORTABILITY LOGIC: This condition is reportable per |
| 10CFR50.72(b)(2)(iii) as an event or condition that alone could have |
| prevented the fulfillment of the safety function of systems or structures |
| that are needed to mitigate the consequences of an accident. [A licensee |
| event report (LER)] is also required within 30 days per 10CFR50.73(a)(2)(v) |
| and (vi). |
| |
| "Additionally, Unit 2 and 3 Technical Specifications Section 3.7.3.D |
| requires [that Limiting Condition for Operation (LCO)] 3.0.3 be entered |
| immediately with two CREV subsystems inoperable. LCO 3.0.3 requires [that] |
| action be initiated within 1 hour to place the affected units in MODE 2 |
| within 7 hours. LCO 3.0.3 was not entered at the time both CREV subsystems |
| were inoperable. Therefore, this condition also requires submission of an |
| LER within 30 days per 10CFR50.73(a)(2)(i)(B), any operation or condition |
| prohibited by technical specifications." |
| |
| The licensee notified the NRC resident inspector. |
| |
| * * * UPDATE AT 1701 ON 1/20/99, BY SWAFFORD TAKEN BY WEAVER * * * |
| |
| The licensee desires to retract this event. The logic for the retraction |
| follows: |
| |
| The initial report was categorized as an event or condition that alone could |
| have prevented the fulfillment of the safety function of systems or |
| structures that are needed to mitigate the consequences of an accident. Both |
| CREV trains were considered inoperable due to Train B undergoing testing |
| following charcoal tray replacement and Train A being incapable of |
| automatically starting on a valid initiation signal due to the primary unit |
| selector switch being in the B position. |
| |
| After further review and successful completion of post maintenance testing |
| of the B train, it has been determined that the B train would have been able |
| to fulfill its safety function during the time it was being tested. The B |
| train was in the required accident alignment during the time the selector |
| switch was in the B position and post maintenance tests confirmed the |
| operability of the train. As a consequence, TVA has concluded that this |
| event does not meet the reporting requirements of 10 CFR 50.72. |
| |
| The licensee informed the NRC resident inspector. Notified |
| R2DO(Christensen). |

| 4-HOUR NRC 91-01 BULLETIN NOTIFICATION INVOLVING ABANDONED EQUIPMENT IN THE |
| X-326 PROCESS BUILDING |
| |
| ON JANUARY 15, 1999, AT 1410 EST IT WAS DISCOVERED THAT THE X-326 PROCESS |
| BUILDING NUCLEAR CRITICALITY APPROVALS (NCSAs) DO NOT DESCRIBE THE |
| OPERATION/CONTROLS FOR THE FOLLOWING ABANDONED IN PLACE EQUIPMENT: PRODUCT |
| PURIFICATION DISTILLATION TOWER, OLD EVACUATION JETS, OLD SO2 REACTOR, OLD |
| PW BOOSTER CONNECTED TO CELL 25-7-15, AND [AN] OLD FREON DEGRADER. |
| |
| "THIS IS REPORTABLE DUE TO NOT HAVING ANY NCSA IN PLACE FOR THIS ABANDONED |
| EQUIPMENT. |
| |
| "THERE WAS NO LOSS OF HAZARDOUS/RADIOACTIVE MATERIAL OR |
| RADIOACTIVE/RADIOLOGICAL CONTAMINATION EXPOSURE AS A RESULT OF THIS EVENT." |
| |
| A PRIOR NRC NOTIFICATION (EVENT #33627) WAS MADE WHICH IDENTIFIED LEGACY |
| EQUIPMENT IN THE X-326 PROCESS BUILDING, HOWEVER, THE ABOVE EQUIPMENT WAS |
| INADVERTENTLY OMITTED. THE EQUIPMENT IS IN GEOMETRICALLY FAVORABLE |
| CONDITIONS AND CONTAINS URANIUM BELOW THE SAFE MASS LIMIT. THIS CONDITION |
| WAS DISCOVERED IN A REVIEW OF COMPLETED NCSAs. |
| |
| THE LICENSEE WILL INFORM THE DOE SITE REPRESENTATIVE AND HAS INFORMED THE |
| NRC RESIDENT INSPECTOR. |

| |
| UPDATE: DUE TO THE PROBLEMS CONCERNING ABANDONED EQUIPMENT IN THE X-326 |
| BUILDING NOT COVERED BY NUCLEAR CRITICALITY SAFETY APPROVALS (NCSAs), A |
| SEARCH PERFORMED IN THE X-705 & X-700 REVEALED ABANDONED EQUIPMENT THAT MAY |
| NEED NCSAs. THE PLANT IS FOLLOWING IT'S PROCEDURE FOR ANOMALOUS NCSA |
| CONDITIONS AND FURTHER EVALUATIONS ARE IN PROGRESS TO DETERMINE IF THIS |
| ABANDONED EQUIPMENT MEETS THE FISSILE MATERIAL LIMITS. THE FISSILE MATERIAL |
| LIMIT OF 15 GRAMS U235 BY PLANT PROCEDURES REQUIRES NCSAs." |
| |
| THERE WAS NO LOSS OF HAZARDOUS/RADIOACTIVE MATERIAL OR |
| RADIOACTIVE/RADIOLOGICAL CONTAMINATION EXPOSURE AS A RESULT OF THIS EVENT. |
| |
| The licensee informed the NRC resident inspector. The Operations Officer |

| |
| DUE TO PROBLEMS CONCERNING ABANDONED EQUIPMENT IDENTIFIED IN THE X-326 |
| BUILDING NOT COVERED BY AN NCSA, A PLANT WIDE SEARCH WAS INITIATED TO |
| IDENTIFY ALL EQUIPMENT WHICH MAY MEET THE FISSILE MATERIAL LIMITS AND WOULD |
| REQUIRE AN ACTIVE NCSA. THIS SEARCH HAS IDENTIFIED THAT THE X-344, X-333, |
| AND THE X-330 BUILDINGS CONTAIN ABANDONED EQUIPMENT THAT WILL REQUIRE AN |
| NCSA. ALL IDENTIFIED EQUIPMENT HAS BEEN BOUNDARIED OFF AND AN ANOMALOUS NCS |
| CONDITION REPORT COMPLETED. |
| |
| THERE WAS NO LOSS OF HAZARDOUS/RADIOACTIVE MATERIAL OR |

| PLANT SHUTDOWN REQUIRED BY TECHNICAL SPECIFICATIONS |
| |
| The licensee commenced a unit shutdown in accordance with Technical |
| Specification (TS) 3.8.1.7 after both standby diesel generators failed to |
| reach required voltage and frequency within the required time (ten seconds) |
| during a surveillance test. The licensee stated that the methodology for |
| the test has been changed, and this was the first test performed using the |
| new methodology. |
| |
| The old test procedure recorded the time for the diesel generators to start |
| and reach required voltage and frequency, although the generators normally |
| overshoot the targets slightly before reaching a steady state value. The |
| revised test methodology records the time for the diesel generators to reach |
| steady state voltage and frequency. The licensee reported that one diesel |
| generator reached steady state within 15 seconds, and the other reached |
| steady state within 22 seconds. |
| |
| The NRC resident inspector has been informed of this event by the licensee. |

| HIGH PRESSURE COOLANT INJECTION (HPCI) INOPERABLE |
| |
| At 1413 on 01/20/1999, the E4150-F022 "HPCI TURBINE EXHAUST DRAIN POT |
| STOP/CHECK VALVE" which drains to the suppression pool, failed to meet |
| stroke time requirements (28.6 sec vs. <=27 sec required). |
| |
| The valve was closed and locked per Technical Specifications 3.6.3 Primary |
| Containment Isolation Valves at 1600. With the E4150-F022 valve closed, |
| it has been determined that the HPCI system is inoperable. This valve path |
| provides a drain path for the drain pot during accident conditions. |
| |
| Repair efforts are in progress. |
