| HIGH PRESSURE COOLANT INJECTION (HPCI) SYSTEM INOPERABLE |
| |
| On 6-26-99 at 0403, the Unit 2 HPCI System was declared inoperable following |
| performance of a routine test on the HPCI drain pot orifice. The purpose of |
| the test is to verify flow through the HPCI turbine exhaust drain pot |
| discharge line flow orifice. At the time of the failure the HPCI System was |
| operable. The HPCI System was conservatively declared inoperable due to the |
| potential for the exhaust line to fill. |
| |
| The licensee notified the NRC Resident Inspector. |
| |
| * * * UPDATE AT 1449 EDT ON 07/23/99 FROM STANLEY GAMBLE TO S. SANDIN * * * |
| |
| The licensee is retracting this report based on the following: |
| |
| The HPCI System was conservatively declared inoperable due to the potential |
| for water to be present in the turbine as a result of a plugged flow orifice |
| on the turbine exhaust drain pot drain line. The plugged orifice was |
| discovered during performance of a test specifically designed to ensure that |
| exhaust drain pot drain line flow path is operable. Testing is routinely |
| scheduled the day following normal HPCI System surveillance testing since |
| operation of the HPCI System is the initiator for plugging of the flow |
| orifice. |
| |
| The basis for this retraction is that a minimal amount, less than one |
| gallon, of condensate was drained from the exhaust drain pot when the flow |
| orifice piping was disassembled. The amount of condensate was much less |
| than the amount required to adversely impact HPCI System operability. It |
| would require in excess of 40 gallons of condensate to fill the exhaust |
| drain pot to a level that would result in condensate entering the turbine or |
| exhaust line. Therefore, the HPCI System was operable and capable of |
| performing its safety function until it was removed from service to clear |
| the flow orifice. |
| |
| The licensee informed the NRC Resident Inspector. |
| |
| The NRC Operations Officer notified R1DO (Jim Noggle). |

| MODE CHANGE INITIATED AS PART OF A TECHNICAL SPECIFICATION REQUIRED |
| SHUTDOWN |
| |
| "At 1810 hours on 7-5-99, with Surry Power Station Unit 2 at Hot Shutdown |
| (HSD) following a reactor trip, the 'A' Cold Leg Loop Stop Valve (Mark |
| number 2-RC-MOV-2591) was removed from it's backseat in accordance with |
| station procedure 2-GOP-2.4. Upon reopening the valve, full open indication |
| was not received. In accordance with Technical Specification 3.17.1 and |
| 3.0.1, a 30 hour clock to Cold Shutdown (CSD) LCO was started. The valve |
| was de-energized by opening it's breaker. A cooldown to CSD was initiated |
| at 2050 on 7-5-99. At 0204 on 7-6-99, a review of Station procedures and |
| 10CFR50.72 determined that a one hour report was required for commencing the |
| RCS cooldown in accordance with the Technical Specification LCO. |
| |
| "There were no radiation releases due to this event, nor were there any |
| personnel injuries or contamination events. |
| |
| "Unit 2 is currently in Intermediate Shutdown with RCS cooldown in progress |
| in accordance with station procedures. |
| |
| "Unit 1 was not affected by this event and remains stable at 100% power and |
| 824 MWe. |
| |
| "This event is being reported in accordance with 10CFR50.72(b)(1)(i)(A)." |
| |
| The Licensee informed the NRC Resident Inspector. |
| |
| * * * UPDATE AT 0940 ON 07/23/99 FROM RAWLEIGH DILLARD TO JOLLIFFE * * * |
| |
| A review of NUREG 1022 with respect to 10CFR50.72(b)(1)(i)(A) provides the |
| following clarification: "the phrase 'initiation of any nuclear plant |
| shutdown' includes action to start reducing reactor power, i.e., adding |
| negative reactivity to achieve a nuclear plant shutdown required by |
| Technical Specifications. The 'initiation of any nuclear plant shutdown' |
| does not include mode changes required by Technical Specifications if |
| initiated after the plant is already in a shutdown condition." |
| |
| Unit 2 achieved Hot Shutdown Mode at 1122 on 07/05/99 after a reactor trip. |
| Based on the information given above in NUREG 1022, a one hour report was |
| not required for commencing the cooldown to Cold Shutdown Mode as this was a |
| mode change after Unit 2 was already in a shutdown condition. The actions |
| taken by the Licensee were prudent and represented a conservative decision |
| by the Licensee. |
| |
| Thus, the Licensee desires to retract the above report based on the above |
| discussion. |
| |
| The Licensee informed the NRC Resident Inspector. |
| |
| The NRC Operations Officer notified the R2DO Ed McAlpine. |

| A LICENSEE VOLUNTARY 24 HOUR NOTIFICATION IS BEING MADE TO REPORT AN INITIAL |
| LACK OF INDEPENDENT ANALYSIS OF BORON CONCENTRATION SAMPLES. |
| |
| Dissolved boron concentration of the spent fuel pool and of the water added |
| to the cavity of a sealed source storage cask is required to be within |
| limits specified in ISFSI Technical Specification Section 3.2.1, Table 3-1 |
| within 4 hours prior to commencing loading operations. The boron |
| concentration is determined using chemical analysis of two samples analyzed |
| by different individuals to reduce the risk that a single error could lead |
| to not meeting the LCO. |
| |
| By procedure, Sample 1 is obtained from the spent fuel pool and from the |
| cask pit by one technician. Sample 2 is then obtained from the spent fuel |
| pool and from the cask pit by a different technician. Sample 1 is to be |
| analyzed by the technician who obtained Sample 2 and vice versa. |
| |
| On 07/19/99, boron concentration sampling was performed prior to loading a |
| spent fuel cask. Technician 1 obtained both cask pit samples and Technician |
| 2 obtained both spent fuel pool samples. Technician 1 then analyzed both |
| cask pit samples and Technician 2 analyzed both spent fuel pool samples. |
| This is contrary to ISFSI Technical Specification Section 3.2.1. Upon |
| realizing the lack of independence in analyzing the samples, Technician 1 |
| analyzed the samples Technician 2 obtained and vice versa. Results of the |
| analysis indicated acceptable dissolved boron concentrations. |

| AUTO REACTOR TRIP FROM 100% POWER FOLLOWING A TURBINE TRIP. |
| |
| AN AUTO REACTOR TRIP OCCURRED FROM 100% POWER FOLLOWING A TURBINE TRIP WHICH |
| OCCURRED FOLLOWING LOSS OF UNIT TRANSFORMER U25,000-12. IT APPEARS THAT THE |
| TRANSFORMER FAULT PROTECTION ACTUATED DUE TO A POSSIBLE LIGHTNING STRIKE TO |
| THE TRANSFORMER. THE FIRE DELUGE SYSTEM FOR THE TRANSFORMER ACTUATED, BUT |
| THERE WAS NO EVIDENCE OF ANY FIRE, WITH THE EXCEPTION OF A SCORCHED PHASE |
| BUSHING WHICH MAY HAVE BEEN THE RESULT OF A LIGHTNING STRIKE. THERE IS NO |
| ESTIMATE OF THE EXTENT OF DAMAGE TO THE TRANSFORMER. ALL CONTROL RODS FULLY |
| INSERTED, NO ECCS INJECTION OCCURRED AND NO SAFETY/RELIEF VALVES APPEARED TO |
| HAVE LIFTED. THE CURRENT HEAT SINK IS THE MAIN CONDENSER. |

| PLANT ENTERED TECH SPEC 3.2.3 LCO ACTION STATEMENT |
| |
| AT 2021 CDT ON 07/25/99, THE "1B21-N500" PRESSURE TRANSMITTER INDICATION |
| DROPPED FROM 1000 PSIG TO INDICATED 600 PSIG REACTOR PRESSURE. THIS |
| TRANSMITTER IS THE PRIMARY PRESSURE TRANSMITTER TO THE ELECTROHYDRAULIC |
| SYSTEM (EHC). DUE TO THIS CHANGE IN PRESSURE INDICATION, THE BACKUP |
| TRANSMITTER TOOK CONTROL. IN THIS LINEUP (BACKUP TRANSMITTER IN CONTROL OF |
| THE EHC), THERE IS NO OTHER BACKUP TRANSMITTER AVAILABLE AND PROCEDURE |
| "LOA-EH-101" STATES THAT THIS CONDITION IS AN UNANALYZED CONDITION AND THE |
| PLANT IS TO ENTER TS 3.2.3. TS 3.2.3 REQUIRES THE REACTOR TO BE <25% POWER |
| WITHIN 4 HOURS. THIS CONDITION WAS NOT DETERMINED TO BE AN UNANALYZED |
| CONDITION UNTIL 2045 CDT ON 07/25/99 UTILIZING THE ABOVE PROCEDURE AND THE |
| UFSAR. THE PROBLEM WITH THE TRANSMITTER IS BEING INVESTIGATED TO DETERMINE |
| WHY IT DOES NOT INDICATE 1000 PSIG. |
| |
| THE RESIDENT INSPECTOR WILL BE INFORMED. |
