EMERGENCY DIESEL GENERATOR VENTILATION EXHAUST DAMPER COVERED WITH SNOW AND ICE

"During performance of a weekly preventive maintenance activity, [it was] discovered that the discharge dampers of Emergency Diesel Generator 102 Exhaust Fans opened approximately one inch vice full open as expected. Technical Specification 3.6.3e 14 day shutdown LCO was entered at 13:40. At 1350, Technical Specification 3.6.3e(1) was entered due to as found condition of both ventilation exhaust dampers for Emergency Diesel Generators 102 and 103 covered with snow and ice preventing normal operation of dampers. This condition required an initiation of normal orderly shutdown in one hour and the Reactor in cold shutdown condition within ten hours. At 14:10, Emergency Diesel Generators 102 and 103 were declared operable based on snow/ice removal and satisfactory completion of testing on all fans and dampers."

The Licensee notified the NRC Resident Inspector.

***** Event Retracted. From Hicks to Taylor on 3/4/04 at 1020 EST*****

"This Event Notification is being made to rescind previous Event Notification made on 2/05/2004. The notification was made as an eight hour report per 10 CFR50.72 (b)(3)(v)(D) and an LER IAW 10CFR50.73(a)(2)(v)(D) and (vi).

"Subsequent Engineering evaluation has concluded that the Emergency Diesel Generators (EDGs), and more specifically their Room Ventilation Fans (Support System) would have performed their design function.

"The specific event described a snow and ice condition that impeded the Ventilation Fan Dampers from fully opening. The dampers did however, partially open. Engineering has concluded that although there was reduced ventilation flow through the dampers, the air flow rate through the reduced exhaust fan opening would have melted the snow and ice. The melting would have occurred at a progressively faster rate (as the exhaust flow rate and room air temperature both increased) and eventually provided adequate ventilation flow to maintain normal room temperature."

Notified R1DO (Todd Jackson).

DEAD FISH FOUND AT CLINTON POWER STATION

The licensee provided the following in accordance with their operating license Appendix B, Environmental Protection Plan.

"At approximately 2100 hrs. on 2/27/04, the Illinois Department of Natural Resources (IDNR) contacted Exelon corporate environmental personnel and informed them there was a fish loss on Clinton Lake. Corporate personnel notified Clinton Power Station personnel at 2130 hrs.

"An inspection on the lake shoreline on 2/28/04 occurred from 0800 to 1200 hrs by station personnel.

"The inspection revealed a total of several hundred deceased fish over several locations. The species predominantly observed were gizzard shad. As followup, the final tally of fish affected will be determined after further communication by CPS environmental personnel working with IDNR.

"The fish appeared have been deceased 3-5 weeks, based on observed decomposition. This 3-5 week time period closely coincides with Clinton Power Station's shutdown on 2/3/04 for refueling outage C1R09."

The Licensee notified the NRC Resident Inspector.

**** Update on 03/04/04 at 1648 EST from Leffel taken by MacKinnon *****

A press release of the dead fish found was issued today, 03/04/04, by the licensee.
R3DO (Jim Creed) notified.

NRC Resident Inspector was notified of this update by the licensee.

NEVADA - AGREEMENT STATE NOTIFICATION OF STOLEN MOISTURE DENSITY GAUGE

"Between 1:30 p.m. and 3:30 pm on March 2, 2004, at Vista & McCarran in Reno, Nevada, a Humboldt Scientific Model 5001 moisture density gauge containing 11 millicuries of Cs-137 and 44 millicuries of Am-241:Be, s/n 1854, was stolen from the transport vehicle. The employee indicated the chain securing the gauge to the pickup bed was cut.

" The Reno, Nevada Police Department was notified."

RCIC STEAM SUPPLY FAILED LLRT

"Appendix J Local Leak Rate Testing [LLRT] of the RCIC Steam Supply failed the Combined Main Steam Isolation Valves leakage limit of 300 scfh. The Combined MSIV leakage limit includes MSIV'S, MSL Drains, HPCI Steam Supply and RCIC Steam Supply. The volume between RCIC Steam Supply valves could not be pressurized therefore, the Minimum Pathway leakage limit is considered to be exceeded.

"This is also considered a failure of the Primary Containment Air Leakage Minimum Pathway leakage limit of 1.0 La.

"The identified degraded condition is reportable as a condition of the nuclear power plant, including its principle safety barriers being seriously degraded per 10CFR50.72(b)(3)(ii) requiring an 8-hr ENS notification."

The RCIC Steam Supply line was tested successfully approximately two years ago during the last refueling outage. The licensee will inform the NRC Resident Inspector.
