j ENCLOSURE 1 l NOTICE OF VIOLATION i

Vermont Yankee Nuclear Power Corporation Docket No. 50-271 i Vermont Yankee License No. DPR-28 l

l During the NRC inspection conducted from April 20 to May 31,1997, 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 nuclear safety operations, surveillance, and testing requirements, shall be prepared, approved, and adhered to.

Vermont Yankee Operating Procedure (OP)-4406, "LPRM Calibration and Functional Check," Revision 13, dated October 18,1996, requires in part, a proper sequence of actions in order to restore the APRMs to a normal mode of operation from the bypass mode used for this periodic calibration.

Contrary to the above, at 9:10 AM on April 24,1997, the Vermont Yankee personnel failed to adhere to written procedures when conducting OP-4406, in that they improperly left the "A" and "D" APRM mode switches in the "ZERO" position and failed to make necessa y adjustments to the APRMs prior to their being removed from bypass, resu' ting in a reactor scram event.

This is a Severity Level IV violation (Supplement 1)

Pursuant to the provisions of 10 CFR 2.201, Vermont Yankee Nuclear Power Corporation is hereby required to submit a written statement or explanation to the U.S. Nuclear Regulatory -Commission, ATTN: Document Control Desk, Washington, D.C. 20555 with a j copy to the Regional Administrator, Region I, and a copy to the NRC Resident inspector at i the facility that is the subject of this Notice, within 30 days of the date of the letter transmitting this Notice of Violation (Notice).
