| REACTOR TRIP SIGNAL DUE TO LOW-LOW STEAM GENERATOR LEVEL. |
| |
| While draining the 1"D" steam generator, a reactor trip signal was generated |
| due to a low-low steam generator level. One train of the reactor protection |
| system was being tested, so one trip breaker opened in response to the trip |
| signal. The low-low steam generator level was due to a planned evolution |
| and was a valid signal. There was no safety significance because all |
| control rods were already inserted into the fuel assemblies, the control |
| rods were not latched to the control rod drive system, and the motor |
| generator sets were shutdown by procedure. Although the reactor trip |
| breaker was closed during testing, at no point was control rod withdrawal |
| possible. They are investigating the cause. |
| |
| The NRC Resident Inspector will be notified |
| |
| **** RETRACTION ON 8/28/02 @08:58 BY THAD REAMES TO ARLON COSTA **** |
| |
| "On September 29, 2002, McGuire Nuclear Station notified the NRC of an |
| inadvertent actuation of the Unit. 1 reactor protection system (RPS) while |
| the unit was shutdown for a refueling outage. This occurred when reactor |
| trip breakers unexpectedly opened as a result of a low-low steam generator |
| level reactor trip signal. This event was reported as a valid actuation of |
| the RPS in accordance with 10 CFR 50.72(b) (3) (iv) (A). Reference Event |
| Report 39229. |
| |
| Further evaluation determined that the reactor trip signal which opened the |
| reactor trip breakers was an invalid signal since it was not initiated in |
| response to plant conditions or parameters satisfying the requirements for |
| initiation of the RPS safety function. Therefore, this represented an |
| invalid actuation which is not reportable per 10 CFR 5Q.72(b)(3)(iv)(A). As |
| a result, McGuire is retracting Event Report 39229. Note that McGuire will |
| report this event in accordance with the requirements of 10CFR 50.73." |
| |
| The Licensee will notify the NRC Resident Inspector. |

| MISSING CPN GAUGE |
| |
| The Licensee had a CPN moisture density gauge in a box of his ATV he uses |
| for transport in the agriculture fields. He stopped at a porta-potty on |
| Duncan Road near Stockton, CA. When he came out of the porta potty the |
| gauge was missing. |
| |
| The gauge is a CPN Hydroprobe model No. 503DR. Serial No: H36107151. Gauge |
| contains 10 millicuries of Cs-137 and 30 millicuries of Am-241. |
| |
| The Licensee will inform the local police of the missing gauge and he will |
| run an offer of a reward in a local newspaper for the recovery of the gauge. |

| RPS ACTIVATION WHILE SHUTDOWN DUE TO LO-LO STEAM GENERATOR WATER LEVEL |
| |
| "On September 29, 2002, McGuire Nuclear Station experienced an inadvertent |
| actuation of the Unit 1 reactor protection system (RPS) while the unit was |
| shutdown for a refueling outage. This occurred when the "A" and "B" train |
| main reactor trip breakers opened as a result of an unplanned low-low steam |
| generator level reactor trip signal. |
| |
| Further evaluation determined that the reactor trip signal which opened the |
| reactor trip breakers was an invalid signal since it was not initiated in |
| response to plant conditions or parameters satisfying the requirements for |
| initiation of the RPS safety function. Therefore, this represented an |
| invalid actuation reportable per the requirements of 10 CFR |
| 50.73(a)(2)(iv)(A). However, as per 10 CFR 50.73(a) (1), McGuire is |
| providing a telephone notification of this invalid actuation instead of |
| submitting a written LER. |
| |
| The following additional information is being provided as part of the |
| telephone notification of this event: |
| |
| -The Unit 1 RPS system including the "A" and "B" train main reactor trip |
| breakers functioned successfully and completely." |
| |
| The Licensee will notify the NRC Resident Inspector. |

| DEGRADATION OF RCS PRESSURE BOUNDARY AT ARKANSAS NUCLEAR ONE UNIT 1 |
| |
| "With the Reactor Coolant System (RCS) In Mode 3 (Hot Standby) conditions at |
| the start of a scheduled refueling outage on October 5, 2002, a leaking weld |
| was discovered at the connection of a drain line to a High Pressure |
| Injection (HPI) line inside the Reactor Building. The leak rate was |
| approximately 0.2 gpm. The immediate evaluation concluded that this leak did |
| not result in the HPI System being inoperable. Subsequent evaluation of the |
| condition on October 8, 2002. determined that the leak was from the RCS |
| pressure boundary. Between the RCS and leak location are a normally open |
| manual isolation valve and a check valve. Weld repair is complete. This |
| condition is being reported as a serious degradation of a principal safety |
| barrier in accordance with 10CFR5O.72(b)(3)(ii)(A)." |

| THE CENTRAL CONTROL ROOM WALL IDENTIFIED AS BEING IN NON-CONFORMANCE WITH |
| DESIGN DRAWINGS |
| |
| Indian Point Energy Center (Unit .2) is making an eight hour non-emergency |
| notification in accordance with 10 CFR 50.72(b)(3)(v)(D). The Central |
| Control Room (CCR) south masonry wall was identified as inoperable because a |
| seismic event could cause breaches in the wall that could prevent the |
| Control Room Air Filtration System from performing its design function of |
| limiting operator dose. |
| |
| The as found condition of the CCR south wall was identified as being in |
| non-conformance with the design drawings. At the top portion of the wall, |
| just above the upper steel channel beam, there are steel angles welded to |
| the lower cord of the CCR roof truss that extend about 1.5 feet towards the |
| south wall. A shelf angle is welded to the ends of the angles that support |
| part of the south wall. This as found condition creates a seismic |
| interaction with the superheater building which transfers load to the south |
| wall through the steel support. Initial analysis indicates that the CCR |
| south wall will remain structurally intact except for several areas in the |
| upper 6 feet of the wall where localized failure could occur. The analysis |
| indicates these localized failures will not cause damage to safety related |
| equipment but may cause loss of the CCR pressure boundary. Corrective |
| action has been initiated to repair the south masonry wall locally and cut |
| the steel causing building interaction between the superheater and control |
| buildings. Corrective action is expected to be complete within |
| approximately 24 hours. |
| |
| Loss of the CCR pressure boundary renders the Control Room Air Filtration |
| System incapable of performing its safety function because it relies on the |
| pressure boundary to limit in-leakage. The Control Room Air Filtration |
| System was declared inoperable and the action statement of Technical |
| Specification 3.3.H was entered at 1330 hours. The action statement allows |
| 3.5 days of continued operation. |
| |
| The NRC Resident Inspector was notified. |
