The licensee reported a loss of ENS and commercial telephone lines due to a loss of power to the phone switch located offsite from the facility. The call was provided as a courtesy notification and the licensee indicated that cell phone and satellite phone communication were still available. These methods of communication were tested and verified to be working satisfactorily. During the initial notification, it was not made clear to the NRC Operations Center that the facility had lost all offsite power and was operating on backup propane generators. The licensee stated that there were no operability problems onsite and that power was expected to be returned to the phone system within approximately 1 hour. Update calls were placed to the licensee by the Headquarters Operations Officer at 1930 EDT and again at 2200 EDT to determine phone status. At the 2200 EDT call, it became clear that the site had also experienced a loss of offsite power. The loss of power was due to a tree that had fallen on a power line away from the site and that the licensee did not have any information on when it would be restored. The licensee stated that all onsite power requirements were being met by a backup propane generator and all facility systems (other than the phones) were operable. The licensee stated that the loss of offsite power was not reportable and the loss of the ENS and commercial lines was reportable as information only. The licensee still did not have information on when the power would be restored. R1DO (Meyer), NMSS EO (Ruland), R1 (Miller) were provided the updated information on the offsite power loss at the site when this information was clarified by the licensee.

ENS 4118810 November 2004 11:22:00Haddam NeckNRC Region 1Westinghouse PWR 4-LoopThe licensee reported that approximately 1000 gallons of "rain water" was being discharged into the licensee's storm drain. The licensee's storm drains discharge into the discharge canal. The licensee noticed a frothing and foaming at the discharge canal as the rain water container was being pumped out. The pumping was discontinued and the licensee is attempting to analyze what substance was in the rain water that might be causing the foaming condition. At this time, the licensee has no information on what substance was discharged or the quantity of the substance that was discharged. The licensee was unable to state how much of the 1000 gallons of rain water had already been discharged. The licensee's discharge canal has a slick boom at the end of the canal but no other mechanism to prevent release of the unknown substance. The licensee notified the Coast Guard, the National Response Center, and the Connecticut Chemical Spill Unit. The licensee also planned to notify the NRC Regional Inspector for the site.
ENS 410894 October 2004 17:59:00Haddam NeckNRC Region 1Westinghouse PWR 4-LoopA significant reduction in the effectiveness of any spent fuel storage confinement system during use This reportability notification addresses a potential unanalyzed condition of 18 Transportable Storage Canisters (TSCs) which are loaded with spent nuclear fuel (SNF). Seventeen of these TSCs are stored in Vertical Concrete Casks (VCCs) at the Haddam Neck Plant Independent Spent Fuel Storage Installation (ISFSI). One TSC is currently in transport operations and will be transferred to the ISFSI in the near future. SNF clad temperature is affected by changes in the TSC internal environment that are encountered during fuel transfer operations. In order to maintain SNF clad temperatures within the analyzed limits, the time duration of certain fuel transfer activities are limited (for example, time in dewatering phase, time in vacuum drying phase and time in helium backfill phase). The canister dewatering section of CY procedures allowed multiple blowdowns of the TSC while in the dewatering time clock. This is contrary to the NAC thermal analysis which assumes a water environment in the canister during the dewatering period. It appears that this condition is not consistent with current analysis assumptions and is therefore a potential unanalyzed condition. NAC International (holder of the C of C) has been advised of this condition and is analyzing the TSC loading conditions. VCC outlet temperatures are within acceptable limits and there is no evidence of unusual radiation exposure in the ISFSI environs.
ENS 410132 September 2004 16:37:00Haddam NeckNRC Region 1Westinghouse PWR 4-LoopHaddam Neck Plant reported that a 20 to 30 gallon diesel fuel oil spill occurred in the containment building from an overturned excavator performing decommissioning work in the containment building.

A recovery plan is being formulated by plant management at this time. Haddam Neck reported this event to the State of Connecticut - Department of Environmental Protection and to NRC Region 1 (John Wray).
ENS 4077927 May 2004 10:57:00Haddam NeckNRC Region 1Westinghouse PWR 4-LoopThe following information was received by the licensee via facsimile: Contamination levels in excess of USDOT (U.S. Department of Transportation) and Barnwell (South Carolina) limits found on a shipment when it reached its destination. (Sea Land Container). No personnel contaminations were reported. The licensee was informed by Barnwell of the contamination event. Apparently, the temperature difference between Connecticut and South Carolina caused condensation to form inside the Sea Land container. The condensation puddled inside the container and then leaked out onto the trailer bed. Contamination was found by Barnwell personnel upon receipt of the trailer. The licensee informed the State of Connecticut Department of Environmental Protection representative on site and NRC Region 1 (John Wray).
