ENCLOSURE 1 NOTICE OF VIOLATION Vermont Yankee Atomic Powe;r Company Docket No. 50-271 Vermont Yankee License No. DPR-28 During the NRC inspection conducted from January 19 to March 8,1997, a violation of NRC requirements was identified in accordance with the " General Statement of Policy and Procedure for NRC Enforcement Actions," NUREG-1600, the violation is listed below:

Technical Specification 6.5, " Plant Operating Procedures," states that detailed written procedures involving both nuclear and non-nuclear safety operations shall be prepared, approved, and adhered to. Vermont Yankee Administrative Procedure (AP)-0125, " Plant Equipment Control," Appendix B, " Conditions Required to Remove Non-Technical Specifications Required Equipment from Service," Revision 7, dated October 31,1995, requires that prior to a planned evolution which will remove from service or otherwise make l inoperable any power supply, the shift supervisor will ensure that a detailed review of loads  ;

impacted by the de-energization of the power supply is completed.

1 Contrary to the above, on November 25,1996, while the reactor was operating at 100 percent power, the shift supervisor did not ensure that a detailed review of loads impacted by the de-energization of 480V electrical bus No. 6 for planned preventive maintenance was conducted prior to its d&energization, resulting in the unanticipated automatic isolation of the in-FcTVICO *;ondensate demineralizers and opening of the associated bypass valve.
