OFFSITE NOTIFICATION OF A DIESEL FUEL OIL SPILL
While flushing diesel generator lube oil to a skid outdoors, one of the hoses came loose, and approximately 500 gallons of diesel lube oil spilled. The spill is now isolated and contained. Some of the oil entered a storm drain, but it is currently believed that none of the oil discharged to the ocean. The spill was reported to the control room at 0153 on 11/26/00.
The licensee notified the New Hampshire State Police, the U.S. Coast Guard, and the National Response Center. The licensee plans to notify the NRC resident inspector.

DISCOVERY OF LOOSE SERVICE WATER PUMP FOUNDATION BOLTS
The following text is a portion of a facsimile received from the licensee:
"At 0154 [CST] on 11/26/00, a station operator noticed that 2 foundation bolts on service water pump (SWP) C were loose and 3 foundation bolts on [SWP] D were loose. Both service water loops were declared inoperable, and [limiting condition for operation (LCO)] 3.7.2, condition A, was entered twice and condition B once. This required placing the plant in Mode 3 within 12 hours and Mode 4 within 36 hours. Personnel were called to the site, and all foundation bolts on all 4 [SWPs] were torqued. No loose bolts were found on SWP A, 4 loose bolts were found on SWP B, and 5 loose bolts were found on SWPs C [and] D. An operability determination was written to justify operability of the service water system, and all LCOs were exited at 0428 [CST]. Engineering [personnel are] evaluation the condition."
The licensee notified the NRC resident inspector.
* * * RETRACTED AT 1244 EST ON 12/14/00 BY STEVEN JOBE TO FANGIE JONES * * *
"Subsequent evaluation has determined that all Service Water Pumps were operable at all times and this event is not reportable under either 10 CFR 50.72(b)(2)(iii)(B) or 10 CFR 50.72(b)(2)(iii)(D).
"Engineering evaluation has determined that a Service Water Pump is operable with one or more pedestal nuts (foundation bolts) having less than installation torque provided a minimum finger tight torque exists. That justification is based on evaluation of loading stress and the impact of not having a preload stress applied to the nut. The determination is that the finger tight nut is an acceptable condition for pump operability. This evaluation has considered the effects of various loading conditions including seismic, barge impact and normal operational loads."
The licensee has notified the NRC Resident Inspector. The R4DO (Chuck Cain) has been notified.
