| *** UPDATE ON 10/29/02 AT 1256ET BY AARON BLESS TAKEN BY MACKINNON**** |
| |
| "After further review of our procedures and the regulatory requirements of |
| 10 CFR 73 Appendix G the licensee has determined the issue of the contraband |
| which was discovered .. .. Located a significant distance from the |
| protected area, on October 2, 2002, to be not reportable. All information |
| was provided expeditiously to the NRC Operation Center during and after the |
| discovery of the contraband , however the event notification is being |
| rescinded due to the fact that the contraband was never introduced or |
| attempted to be introduced into the protected area, material access area, |
| vital area, or transport. The NRC Security Safeguards Staff of Region III |
| has been informed of the plans to rescind the event notification." R3DO |
| (Jim Creed) notified. |

| AUXILIARY FEEDWATER SYSTEM (AFWS) DECLARED INOPERABLE |
| |
| "At 10:27 CST, the auxiliary feedwater system (AFWS) for Point Beach Nuclear |
| Plant, Units 1 and 2, was declared inoperable due to the potential for |
| fouling of the minimum recirculation orifices for each of the four AFW |
| pumps. The mechanism identified was the potential for foreign materials in |
| the AFW fluid restricting adequate flow through the flow control orifices in |
| the recirculation line. Under such conditions, it is possible that if the |
| discharge valves for the AFW pumps are throttled, adequate flow may be |
| unavailable through the recirculation line and pump damage could occur. |
| |
| "The potential for this common failure mode was realized while conducting an |
| extent-of-condition evaluation for reduced recirculation flow observed |
| during surveillance testing of the P-38A motor driven AFW pump on October |
| 24, 2002. The flow was less than expected but above the minimum required |
| for pump operability. Upon disassembly of the P-38A flow orifice we |
| discovered a build up of corrosion products in the orifice. |
| |
| "Both units entered Tech Spec [Action Condition] 3.7.5.E and required action |
| 3.7.5.E.1 which requires immediate steps to restore an AFWS to operable |
| status. Immediate corrective actions have consisted of briefing the |
| on-shift crew (on-coming crews will also be briefed) of the potential |
| consequences of restricted recirculation flow and directing the operators, |
| in the event of a situation requiring AFW flow, to secure a running AFW pump |
| if the pump discharge falls below minimum flow requirements. In addition, |
| information tags have been attached by the AFW pump flow indicators on the |
| main control boards to convey that information. These action were completed |
| at 1305 CST. At that time, with these administrative controls in place, we |
| declared the AFWS back in service. Longer term corrective actions, |
| including permanent procedure changes, are being evaluated." |
| |
| The NRC Resident Inspector was notified of this event by the licensee. |
