| UNIT 1 VALVES FAILED THEIR LOCAL LEAK RATE TEST. |
| |
| UNDER THE APPENDIX J PROGRAM PLAN (#NMP1-APPJ-001) SECTION III/1.8 OUTAGE |
| TESTING REQUIREMENTS INCLUDE MAINTAINING A COMBINED TOTAL TYPE 'B' AND 'C' |
| AS-FOUND MINIMUM PATHWAY LEAKAGE. IN ACCORDANCE WITH TECH SPEC 6.16.4, THE |
| COMBINED LOCAL LEAK RATE TEST (TYPE 'B' & 'C' TESTS INCLUDING AIRLOCKS) |
| ACCEPTANCE CRITERIA IS LESS THAN 0.6 La, CALCULATED IN THE MINIMUM PATHWAY |
| BASIS, AT ALL TIMES WHEN CONTAINMENT INTEGRITY IS REQUIRED. THE VALUE OF |
| 0.6 La FOR UNIT 1 WAS CALCULATED TO BE 388.44 SCFH. THE RESULTS OF THE TEST |
| MEASURED 388.756 SCFH, WHICH EXCEED THE CALCULATED VALUE FOR THE COMBINED |
| AS-FOUND TYPE 'B' AND 'C' LOCAL LEAK RATE TESTS. THIS CONDITION WOULD HAVE |
| BEEN A TECH SPEC VIOLATION IF IDENTIFIED DURING POWER OPERATION. |
| |
| THIS CONDITION WILL BE CORRECTED PRIOR TO PLANT RESTART. |

| THE LICENSEE INFORMED THE NRC RESIDENT INSPECTOR. |

| DIV 1 EDG INITIATION AND RHR LPCI "A" & LPCS INJECTION INTO THE RPV DUE TO |
| AN INVALID SIGNAL |
| |
| WITH THE PLANT IN OPERATIONAL CONDITION 5 IN A REFUELING OUTAGE, THE START |
| OF THE DIVISION 1 EMERGENCY DIESEL GENERATOR (EDG) AND INJECTION INTO THE |
| REACTOR PRESSURE VESSEL (RPV) VIA THE RESIDUAL HEAT REMOVAL (RHR) LOW |
| PRESSURE COOLANT INJECTION (LPCI) "A" AND LOW PRESSURE CORE SPRAY (LPCS) |
| SYSTEMS OCCURRED DUE TO AN INVALID EMERGENCY CORE COOLING SYSTEM INITIATION |
| SIGNAL. |
| |
| THE CAUSE OF THE INITIATION SIGNAL WAS A FAILED ROSEMONT TRIP UNIT |
| (#B21-N671A), WHICH WAS NEWLY INSTALLED AND PLACED INTO SERVICE DURING THE |
| PRESENT REFUELING OUTAGE IN |
| RESPONSE TO THE SAFETY/RELIEF VALVE LOGIC SMART FIRE ISSUE. WHEN THE TRIP |
| UNIT FAILED, IT AFFECTED POWER TO THE DIVISION 1 INSTRUMENT RACK RESULTING |
| IN THE GENERATION OF AN INVALID RPV LEVEL 1 INITIATION SIGNAL CAUSING THE |
| ESF ACTUATIONS. PLANT OPERATORS VERIFIED THE REACTOR CAVITY LEVEL AND |
| IMMEDIATELY OVERRODE THE OPEN INJECTION VALVE SIGNAL TO STOP THE INJECTION. |
| APPROXIMATELY TWO INCHES OF WATER HAD BEEN ADDED TO THE REACTOR CAVITY LEVEL |
| FROM THE SUPPRESSION POOL. THE EDG DID NOT LOAD AND WAS SECURED AFTER |
| APPROXIMATELY TWO HOURS. |
| |
| WHEN THE OPEN LPCS INJECTION VALVE SIGNAL WAS OVERRIDDEN, THE SYSTEM MINIMUM |
| FLOW VALVE DID NOT REOPEN AND CONTROL ROOM OPERATORS OPENED THE MINIMUM FLOW |
| VALVE TO PROVIDE LPCS PUMP PROTECTION. ALSO, THE RHR "A" INJECTION CHECK |
| VALVE WAS STILL INDICATING OPEN (UNCLEAR IF THIS IS AN INDICATION PROBLEM OR |
| A STUCK OPEN VALVE PROBLEM) AFTER THE INJECTION VALVE HAD BEEN SHUT. THE |
| LICENSEE IS INVESTIGATING BOTH OF THESE CONDITIONS. |
| |
| THE LICENSEE INFORMED THE NRC RESIDENT INSPECTOR. |
