SUBJECT:

NRC INSPECTION REPORT NO. 50-271/99-12 AND NOTICE OF VIOLATION

Dear Mr. Wanczyk-

On August 11,1999, the NRC completed an inspection at your Vermont Yankee (VY) facility.

' The inspector was on site during the week of June 28 to July 1,1999. Additional in-office

inspection of materials supplied by your staff was com' leted on August 11,1999.. The enclosed

p

report presents the results of the inspection. At the conclusion of this inspection, these findings

were discussed with members of your staff.

The inspection focused on your maintenance rule periodic evaluation. Except as described

below, your evaluatiyn met the requirements of the maintenance rule.

Based on the results of this inspection, a ' violation of NRC requirements was identified. Failure

to monitor unavailability of specific systems, structures, and components (SSCs) during the

. refueling outage did not allow an adequate assessment of maintenance effectiveness on a

number of risk significant systems, and did not allow balancing reliability and unavailability of risk

'significant systems (or functions). This is a violation of 10 CFR50.65(a)(3). Also, if unavailability

had been properly monitored and performance measures properly established, some of the risk

significant systems could have required corrective action programs and placement of the system

.

into the (a)(1) category. The violation has been categorized at Severity Level IV in accordance

with the " General Statement of Policy and Procedure for NRC Enforcement Actions,"

(Enforcement Policy), NUREG-1600, Revision 1.

- This violation is being cited because it was identified by the NRC and was repetitive as a result

of inadequate corrective actions for a previous violation of 10 CFR 50.65. In February 1998, a

Severity Level IV violation was cited for failure to monitor unavailability of risk significant SSCs

/

, during refueling outages contrary to 10 CFR 50.65(a)(2). At that time, you were also informed

/

'

that the failure to properly monitor unavailability during a refueling outage could also result in

ineffective periodic balancing of reliability and unavailability as required by 10 CFR 50.65(a)(3).

.While your corrective action to measure the unavailability of key plant safety functions during the

refueling outages was sufficient to meet the requirements of 10 CFR 50.65(a)(2), your actions

should also have reasonably prevented the current violation of 10 CFR 50.65(a)(3) for balancing

reliability and unavailability. FWher, you have not placed the current violation into your

correctiva action program.
