SUBJECT:

NRC SPECIAL INSPECTION REPORT 50-271/98-80, NOTICE OF VIOLATION

AND EXERCISE OF ENFORCEMENT DISCRETION

Dear Mr. Maret:

On June 5,1998, the NRC completed an engineering inspection at the Vermont Yankee as

part of the core inspection program. The team found your engineering organization

continuing its transition to a site-based organization and that your engineering programs

were also working toward that goal. The team also found that your corrective action

program had improved since the last 40500 inspection in 1996 noted that had

opportunities for further improvement existed in event report trending and deportability

screening.

During this inspection five violations of NRC requirements were identified. The first

concerns an inadequate safety evaluation for the control room HVAC temporary

modification. The second violation concerns inadequate corrective action for a design

deficiency associated with the control room HVAC system. The third violation concerns

failure to report a condition that could have prevented the control room HVAC system from

performing its intended function. The fourth violation concerns inadequate design control

for f ailing to control Design Basis Document changes. The fifth violation concerns

reducing commitments contained in the NRC approved QA Program without prior NRC

approval.

The violations are cited in the enclosed Notice of Violation, and the circumstances

surrounding the violations are described in detailin the enclosed report. Please note that

you are required to respond to this letter and should follow the instruction.s specified in the

enclosed Notice when preparing your response. The NRC will use your response, in part,

This report also discusses a non-cited violation (NCV) associated with an unreviewed

p9

safety question related to the safety evaluation for the 1974 modification to the HPCl/RCIC

vacuum breakers. This NCV involved an old design issue that apparently resulted from an

inadequate safety evaluation, and was a violation of NRC requirements which could be

considered for escalated enforcement and subject to a civil penalty. However, after

consultation with the Director, Office of Enforcement, and the Regional Administrator, I

have been authorized to not issue a Notice of Violation and not propose a civil penalty in

this case in accordance with the provisions provided in Section Vll.B.3 of the NRC's

Enforcement Policy. This decision was made after consideration that: (1) the violation was

identified by your staff's good questioning attitudes during a voluntary initiative; (2)

. corrective actions,.both taken and planned, were comprehensive and timely; (3) the

condition was subtle in nature and not likely to be disclosed through routine surveillance or

quality assurance activities; and (4) the violation was not reasonably linked to current

performance. The exercise of discretion acknowledges your good effort to identify and

correct subtle violations, that would not be identified by routine efforts, before the

degraded safety systems are called upon.

The response directed by this letter and the enclosed Notice are not subject to the

clearance procedures of the Office of Management and Budget as required by the

Paperwork Reduction Act of 1980, Pub. L. No.96-511. In accordance with 10 CFR %790

of the NRC's " Rules of Practices," a copy of this letter and its enclosures will be placed in

the NRC Public Document Room.

In accordance with 10 CFR 2.790 of the NRC's " Rules of Practices," a copy of this letter

and the enclosed Notice will be placed in the NRC Public Document Room.

Sincerely,
