| CONTROL ROOM EMERGENCY FILTRATION SYSTEM INOPERABLE |
| |
| At 1528 the Control Room Emergency Filtration System (CREFS) was declared |
| inoperable when fire door H305 was noted to hang open instead of fully |
| closing when personnel passed through the door. BLDG-DOOR-H305 is a |
| Control Room Envelope Door. CREFS is a single train system. When CREFS |
| was determined to be inoperable Technical Specification LCO 3.7.4 condition |
| A was entered. This LCO requires the restoration of CREFS to OPERABLE |
| status within 7 days or be in MODE 3 within 12 hours and MODE 4 within 36 |
| hours. |
| |
| Following the transfer of CREFS to DIV 1 power at 13:30, it was subsequently |
| noted that the control room blast doors seemed harder to open than normal. |
| The ventilation lineup for the Control Building was verified to be correct. |
| During this verification it was determined that BLDG-DOOR-H305 would not |
| operate properly and the door and CREFS were declared inoperable. |
| |
| Ventilation flow through other Control Room Boundary Doors appears [to]be |
| abnormal for the present ventilation lineup. A Fire Watch has been |
| stationed at BLDG-DOOR-H305. A Problem Identification Report has been |
| initiated to identify that BLDG-DOOR-H305 will not close by itself from the |
| fully open position. The ventilation lineup has not been changed since the |
| discovery of this condition for evidence preservation. The Ventilation |
| System Engineer is responding to the Site to assist with troubleshooting of |
| the ventilation system. |
| |
| The licensee notified the NRC resident inspector. |
| |
| * * * UPDATE 1514EST ON 3/1/01 FROM DAVID VANDERKAMP TO S. SANDIN * * * |
| |
| The licensee is retracting this report based on the following: |
| |
| "Basis for Retraction: |
| |
| "Event Number 37673 reported a condition at Cooper Nuclear Station (CNS) |
| where the Control Room Emergency Filtration System (CREFS) was declared |
| inoperable. This was a result of the control room envelope boundary being |
| declared inoperable due to a fire door not closing automatically when it was |
| opened raising questions about integrity of the envelope. |
| |
| "On a specific occasion, a fire door that allows access from the control |
| room access hall to the computer room, was unable to close without |
| assistance. This was discovered when an operator passed through the door and |
| it failed to close behind him. He had to manually assist the door closed. |
| The door was declared inoperable as a fire boundary door and a fire watch |
| was posted. Since the door forms part of the control room envelope boundary, |
| that boundary was also declared inoperable due to concerns about the |
| envelope integrity. Therefore, CREFS was declared inoperable. |
| |
| "Technical Specifications require that the control room envelope be |
| maintained at a positive pressure in the emergency line-up on the control |
| room ventilation system but not in the normal line-up. This should be |
| considered a normal operation of the door for entry and exit per Technical |
| Specification Bases 3.7.4. This states that: |
| |
| '...in addition, the control room boundary must be maintained, including the |
| integrity of the walls, floors, ceilings, ductwork and access doors, such |
| that the pressurization limit of SR 3.7.4.4 can be met. However, it is |
| acceptable for access doors to be open for normal control room entry and |
| exit, and not consider it to be a failure to meet the LCO.' |
| |
| "There was no condition present that would challenge the integrity of the |
| Control Room envelope, other than the door not closing automatically. The |
| door was manually closed while being used for access. Signs are posted at |
| doors that should be closed to ensure that doors are closed after they are |
| opened. The operator passing through this door closed the door when it would |
| not close by itself. Not withstanding the fact that the door was |
| closed as required; a Fire Watch was posted to better ensure that the door |
| was properly closed until the reason for it's not automatically closing was |
| determined. No major components failed. |
| |
| "The cause of the door not automatically closing was determined to be a |
| mis-positioned, manually operated damper. The mis-positioned damper caused a |
| decreased positive pressure inside the Control Room envelope boundary |
| impacting the automatic door closure. If an accident had occurred while this |
| damper was mis-positioned, the Control Room Emergency Filtration System |
| would have performed its safety function as designed and continued to be |
| operable. |
| |
| "Based on this updated information, the District has determined that this |
| event is not reportable under the requirements of 10CFR50.72(b)(2)(iii)(D), |
| and as such, event 37673 is retracted." |
| |
| The licensee will inform the NRC resident inspector. Notified R4DO(Howell). |

| REACTOR WAS MANUALLY TRIPPED AT LESS THAN 1% POWER |
| |
| |
| A manual reactor trip was initiated at 0017 on 3/01/01 due to 2 shutdown |
| control rods remaining on the bottom while initiating control rod |
| withdrawal. This occurred during low power physics testing and a trouble |
| shooting plan for a misaligned Shutdown bank B Control rod (G-9). The rod |
| had already been realigned to the other rods in shutdown bank B @ 43 steps. |
| The Shutdown bank was inserted into the core to zero steps per the trouble |
| shooting plan. After the step counters and rod control were reset and |
| Shutdown bank B rods were being withdrawn, it was discovered that 2 rods had |
| not moved and were still on the bottom with 14 steps demanded. The Shutdown |
| bank was re-inserted to zero steps (fully inserted). After further |
| discussion, the shift supervisor called for a manual reactor trip. The |
| reactor operator tripped the Reactor and the Crew entered the Emergency |
| Operation Procedures (EOP-1.0, Reactor trip/safety injection, and EOP-1.1, |
| Reactor trip recovery). All systems functioned as designed. The problem |
| with the rod control system is not understood and trouble shooting is |
| continuing. |
| |
| |
| Note: The 2 rods that did not move were rods G-9 and L-5, both in Shutdown |
| bank B. |

| MANUAL REACTOR TRIP DUE TO LOSS OF OPERATING CIRCULATING WATER PUMPS |
| |
| "South Texas Project Unit 2 makes the following report in accordance with |
| 10CFR50.72(b)(2)(iv)(B) and 50.72(b)(3)(iv)(A): |
| |
| "At 08:22 CST on 3/01/01, a manual Reactor Trip was initiated due to failure |
| of a switchyard breaker and subsequent loss of all operating Circulating |
| Water Pumps. All Control Rods fully inserted into the Reactor Core. The |
| Auxiliary Feedwater system actuated on low-low Steam Generator Water Level |
| and a Feedwater isolation signal occurred as expected on a trip from 95% |
| power. Pressurizer heater group 'A' did not energize on low RCS pressure as |
| required. Cause of the heater group to fail to energize is not known at this |
| time. All four (4) Reactor Coolant pumps remain in operation and decay heat |
| is currently being removed via the atmospheric steam dumps. No radiation |
| above state, federal, and plant operational limits was measured by South |
| Texas Project's radiation monitoring system." |
| |
| The licensee is presently making efforts to restore an operating Circulating |
| Water Pump so as to establish Main Condenser vacuum. Three Circulating |
| Water Pumps were operating at the time with the fourth out-of-service. The |
| licensee has a measured 20gpd Steam Generator tube leakage. The offsite rad |
| release is within allowable limits. No other safety equipment is out of |
| service. The licensee informed the NRC resident inspector. |

| ALERT NOTIFICATION SYSTEM DISCOVERED INOPERABLE |
| |
| "At 0955, KNPP was notified by the Kewaunee County Sheriffs Office of a |
| disconnected cable which supplies the siren encoder for the Alert |
| Notification System. Subsequent investigation identified that the |
| transmitter was removed during remodeling, disabling the system from being |
| activated by the Kewaunee County Dispatch Office, potentially as early as |
| Monday, 2/26/01. Normal siren activation would be accomplished from the |
| Algoma Emergency Operations Center, but the Kewaunee Dispatch location would |
| be used in the event of a fast breaking incident. It is believed that |
| processes in place would have lead the Kewaunee Dispatch to pursue alternate |
| methods of activating the sirens, however, it is not clear that this would |
| have been performed in a timely manner. Compensatory measures have been |
| established for the Kewaunee Dispatch/Sheriff to notify the Kewaunee |
| Emergency Director of the need to activate the sirens. The Emergency |
| Director has the capability to activate the sirens remotely and will |
| maintain this activation function manned until the equipment issues at the |
| Kewaunee Dispatch have been resolved." |
