ENCLOSURE 1 i NOTICE OF VIOLATION  ;

i Vermont Yankee Nuclear Power Corporation Docket No. 50-271 Vermont Yankee Nuclear Power Station License No. DPR-28 During an NRC inspection conducted from May 23 to June 26,1993, a violation of NRC requirements was identified. In accordance with the " General Statement of Policy and  ;

, Procedure for NRC Enforcement Actions," 10 CFR Part 2, Appendix C (1992), the violation l is listed below:  :

Technical Specification 3/4.2.A., Table 3.2.1 requires, in part, that the core spray high sparger pressure instruments be calibrated to a setpoint of less than or equal to 5 ;

pounds per square inch differential (psid). i Contrary to the above, on May 27,1993, Vermont Yankee determined that due to improper calibration of the core spray high sparger pressure instruments, both the l "A" and "B" instrument setpoints exceeded the Technical Specification limit. This condition existed since November 1979.
