| TRIP ROLLER - HK CIRCUIT BREAKER, ABB PART # 180097A00 |
| |
| During the 4kV ABB Type HK breaker refurbishment at the DC Cook Plant on |
| October 21, 1999, newly installed trip rollers, ABB Part Number 180097A00, |
| were determined to be below the minimum hardness specification, Rockwell C |
| 50-55. One roller was observed to be "scoring" after 200 cycles. This |
| roller was one of 130 rollers sent to DC Cook through a purchase order from |
| ABB Service Company in Cleveland, Ohio. A sample of rollers indicated that |
| all were below the hardness specification. After communicating this to ABB |
| Service and the ABB Florence facility, the roller with the lowest measured |
| hardness, Rockwell C13, was returned for evaluation at the ABB-Florence |
| factory. |
| |
| ABB Power T&D Company received notification from ABB Service Company, The |
| Woodlands, TX, of a trip roller, 180097A00, problem occurring in November |
| 11, 1998, purchased under ABB Service Company Purchase Order Number |
| 27-04459-P4031, ABB Power T&D Company Order Number CCN0449. The initial |
| investigation points to a roller that has not been heat-treated to its |
| hardness specification as well. This information will serve to address the |
| trip roller issue here as well. |
| |
| An HK Circuit Breaker that contains trip rollers that are not properly |
| hardened may fail to trip at some point during the life of the breaker. ABB |
| Power T&D Company testing indicates that a very soft trip roller measuring |
| Rockwell C13 was able to operate 4000 operations before minimum trip voltage |
| failed to operate the circuit breaker. |
| |
| The information of the defect of the trip roller was obtained on October 21, |
| 1999 |
| |
| This information affects trip rollers that were shipped as Component Orders |
| or as part of Complete Circuit Breakers from October 30, 1995 through June |
| 1999. |
| |
| The hardness critical characteristic was added to the QC Record Card in June |
| 1999 for the trip roller, 180097A00. |
| |
| ABB will notify all customers who purchased this product. |
| |
| Replacement trip rollers may be obtained from ABB Power T&D Company, |
| Sanford, FL, by contacting the Components Group. |

| TECHNICAL SPECIFICATION VIOLATION DISCOVERED |
| |
| The licensee has determined that Tech Spec 3.4.2, which limits the amount of |
| explosive material in the reactor to less than 25 milligrams has been |
| exceeded. Following an investigation of bulging of the reactor reflector in |
| October this year it has been determined that an accumulation of hydrogen |
| and oxygen gas of approximately 5000 times the Tech Spec limit has |
| accumulated in the reflector. The reflector is graphite, contained an |
| aluminum can, doughnut shaped, that fits around the reactor. Apparently, a |
| pinhole sized leak allowed water from the reactor pool to seep into the |
| reflector can, which then underwent radiolytic decomposition filling the can |
| with hydrogen and oxygen gas. The reflector has been ultrasonically |
| examined to determine if it was full of water and it is not. |
| |
| The licensee has and is consulting experts concerning their plan to vent the |
| gasses out of the reflector under water in a slow and controlled manner. |
| The reactor is defueled and will remain so until this problem is corrected. |
| |
| The licensee notified the NRC Project Manager concerning this issue. |

| CONTAINMENT SUMP LEVEL DETECTION DOES NOT MEET REQUIREMENT FOR RCS LEAK |
| DETECTION |
| |
| "While investigating concerns with the containment instrument tunnel sump |
| leak detection capabilities and satisfying the requirements for RCS leak |
| detection in the Improved Tech Specs (TS 3.4.15) an issue was identified |
| with the Normal Containment Sump Level Monitoring capability. From review |
| and investigation of this issue, it was identified that the current |
| calculation for the instrument tunnel sump leak rate would not always be |
| able to detect a 1 gpm leak in one hour to satisfy the Reg Guide 1.45 basis |
| for this Tech Spec. After even further review, it has been concluded that |
| the current calculation for the containment normal sumps is performed in a |
| similar manner. Thus, the containment normal sumps will not always provide |
| adequate leak detection to ensure that a 1 gpm RCS leak is detected in one |
| hour. |
| |
| "The Wolf Creek Updated FSAR states that one of the design bases of the |
| reactor coolant system leakage detection systems is to be capable of |
| detecting a 1 gallon per minute leak consistent with Regulatory Guide 1.45 |
| and 10 CFR 50, Appendix A, General Design Criteria 30. Regulatory Guide 1.45 |
| states that the systems must be capable of detecting a 1 gpm leak within 1 |
| hour. Since the Wolf Creek Containment Normal sump does not meet this design |
| basis, it is believed that the plant may be outside its design basis, in |
| accordance with the reporting criteria of 10 CFR 50.72(b)(1)(ii)." |
| |
| The fix is a software change to the Plant Computer and the licensee has it |
| and intends to have it in operation well within the 30 day shutdown |
| requirement of Tech Specs. |
| |
| The licensee has notified the NRC Resident Inspector. |

| MANUAL REACTOR TRIP AFTER MAIN FEEDWATER PUMP TRIP ON LOW SUCTION PRESSURE |
| |
| The reactor was manually tripped (all rods fully inserted) after two of |
| three main feedwater pumps tripped due to low suction pressure. The low |
| suction pressure was due to a secondary system transient which caused the |
| loss of one of the high pressure heater drain pumps. The transient was from |
| feedwater heater level system. The exact cause is under investigation. |
| |
| All auxiliary feedwater pumps started, as designed, on low steam generator |
| level and the steam dumps opened to the condenser to remove excess heat. |
| The unit is stabilized in Mode 3. |
| |
| The licensee intends to notify the NRC Resident Inspector. |

| PERFORMANCE OF RHR LOGIC FUNCTIONAL TEST DEFEATS THE AUTOMATIC START OF ALL |
| FOUR RHR PUMPS |
| |
| A review of the Residual Heat Removal (RHR) logic system functional test |
| identified that during part of the performance of the test the automatic |
| start of all four RHR pumps was defeated. Manual initiation remained |
| available. This test was last performed on both Unit 2 and Unit 3 in 1997. |
| This report is being made due to the loss of the automatic initiation of the |
| Low Pressure Coolant Injection (LPCI) mode of RHR. This alone could have |
| prevented the fulfillment of a safety function. |
| |
| The NRC Resident Inspector will be notified of this event by the Licensee. |
