SUBJECT:

NRC RESIDENT INSPECTION REPORT 50-010:237:249/96014(DRP) AND

NOTICE OF VIOLATION

Dear Mr. Perry:

This refers to the inspection conducted on October 21 through December 6,

1996, at the Dresden Nuclear facility.

The )urpose of the inspection was to

determine whether activities authorized by t1e license were conducted safely

and in accordance with NRC requirements.

During this period, routine resident

inspections were performed.

Based on the inspectors' findings, overall

performance at the Dresden facility was safe.

At the conclusion of the

'

,

inspection the findings were discussed with those members of your staff

,

identified in the enclosed report.

'

Based on the results of this inspection, one apparent violation was identified

and is being considered for escalated enforcement action in accordance with

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

(Enforcement Policy) NUREG-1600. The apparent violation involved the failure

i

to perform post-modification testing of control room emergency ventilation

i

system to ensure design recuirements were maintained.

This licensee

identified issue, describec in Section E2.1 of the enclosed report, is of

,

concern because design modification testing controls were inadequate to ensure

'

system operability was maintained.

In addition, your engineering backlog

.

reviews conducted in the spring of 1996 failed to identify the potential for

l

significant system degradation due to the open control room modification

packages. As a result, the control room was found not capable of maintaining

the required positive pressure or in-leakage limitations.

The as-found

degradation was significant in that the potential may have existed for control

room radiological doses to be in excess of regulatory limits following a

design basis accident.

The circumstances surrounding the apparent violation, the significance of the

issue, and corrective actions were discussed with members of your staff at the

exit meeting on December 19, 1996.

An open pre-decisional enforcement

l

conference to discuss these apparent violations has been scheduled for

February 28. 1997, at 10:00 a.m. (CST) in the Region III Office in Lisle.

'

Illinois.

The decision to hold a pre-decisional enforcement conference does

enforcement action will be taken. This conference is being held to obtain

i

information such as a common understanding of the facts, root causes. missed

i

opportunities to identify the apparent violation sooner, corrective actions,

r

significance of the issues, and the need for lasting and effective corrective

!

action to enable the NRC to make an informed enforcement decision.

t

During the enforcement conference we expect you to address:

(1) the

i

circumstances resulting in the apparent violation: (2) your methods to ensure

!

post-modification testing is com)leted in a timely manner: (3) the corrective

steps that have been taken and t1e results achieved; (4) the corrective steps

'

that will be taken to avoid further violations; and (5) the date when full

,

compliance will be achieved. These discussions should not be limited solely

to the control room heating. ventilation, and air conditioning (HVAC) system.

In addition. this is an opportunity for you to point out any errors in our

'

inspection reports and for you to provide any additional information

concerning your )erspectives on:

(1) the severity of the violations. (2) the

application of t1e factors that the NRC considers when it determines the

amount of a civil penalty that may be assessed in accordance with Section

VI.B.2 of the Enforcement Policy, and (3) any other application of the

,

Enforcement Policy to this case, including the exercise of discretion in

i

accordance with Section VII.

i

In accordance with the Enforcement Policy, no Notices of Violation are

presently being issued for these ins)ection findings.

Please be advised that

the number and characterization of t1e apparent violation described in the

enclosed inspection report may change as a result of further NRC review.

You

1

will be advised by separate correspondence of the results of our deliberations

i

on this matter.

No response regarding the apparent violation is required at

this time,

t

In addition to the concerns described above. an additional violation of NRC

l

requirements was identified this period. The violation involves a failure to

ensure that vendor technical information is controlled in accordance with your

approved station procedures. This issue is of concern. because during

previous inspections. the vendor equipment technical information program

(VETIP) was a major topic, and the need for strong controls was clearly

necessary to reduce your existing backlog. The emergency diesel generator

(EDG) manual, which had information missing, was one of the manuals that had

been processed through VETIP and was believed to be complete and correct.

Our

inspection identified this was not the case.

The violation is cited in the enclosed Notice of Violation (Notice), and the

circumstances surrounding the violation is described in detail in the enclosed

report.

Please note that you are required to respond to this letter and

should follow the instructions specified in the enclosed Notice when preparing

your res]onse.

Your response should include a discussion of your efforts to

ensure tlat the VETIP procedures are being followed by your staff.

Additionally, describe your efforts to ensure that all previously revised and

approved manuals are complete and correct. The NRC will use your response, in
