SUBJECT:
DAVIS-BESSE SPECIAL INSPECTION REPORT 50-346/98021(DRP)
Dear Mr. Campbell:
On May 13,1999, the NRC completed an inspection at your Davis-Besse site. The purpose of
' the inspection was to review the circumstances surrounding the discovery of two missing
body-to-bonnet nuts on pressurizer spray valve RC-2. The enclosed report presents the results
of that inspection.
Based on the results of this inspection, two apparent violations were identified and are 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
first apparent violation concems the failure to ensure adequate material separation was
maintained during RC-2 maintenance activities which resulted in the installation of three carbon
steel body-to-bonnet nuts on the valve. Two of these nuts completely corroded away and the
third had partially corroded away from the effects of boric acid contained in an RC-2 packing
leak. The second apparent violation concerns the failure to take prompt, effective corrective
actions to identify and correct this condition after the discovery of one missing body-to-bonnet
nut. The degraded condition of RC-2 with one partially corroded nut and two missing nuts
required a detailed evaluation to determine if it would have functioned under all design loads.
Although your staff initially determined that the valve would not have functioned under extreme
design conditions, the results of a more detailed calculation indicated that it would have
functioned under all design loads. Once it was identified that boric acid corrosion was the
cause of the missing nuts, a comprehensive review of the condition occurred and thorough,
effective corrective actions were taken.
The circumstances surrounding these apparent violations, the significance of the issues, and
the need for lasting and effective corrective action were discussed with you at the exit meeting
on May 13,1999. As a result, it may not be necessary to conduct a predecisional enforcement
conference in order to enable the NRC to make an enforcement decision. In addition., since
your facility has not been the subject of escalated enforcement actions within the last 2 years,
and based on our understanding of your corrective actions, a civil penalty may not be warranted
in accordance with Section VI.B.2 of the Enforcement Policy.
Before the NRC makes its enforcement decision, we are providing you an opportunity to either
(1) respond to the apparent violation addressed in this inspection report within 30 days of the
date of this letter, (2) request a predecisional enforcement conference, or (3) inform the NRC
i
that the subject inspection report and Licensee Event Report (LER) 50-346/98-009 already
contain the information requested in the next paragraph and that you will not provide a

response. If a conference is held, it will be open for public observation. The NRC will also
issue a press release to announce the conference. Please contact Tom Kozak at
630/829-9866 within 7 days of the date of this letter to notify the NRC of your intended
response.
Your response, if you elect to provide one, should be clearly marked as a " Response to
Apparent Violations in inspection Report 50-346/98021(DRP)," and should include the following
information for each apparent violation: (1) the reason for the apparent violation, or, if
contested, the basis for disputing the apparent violation, (2) the corrective steps that have been
taken and the results achieved, (3) the corrective steps that will be taken to avoid further
violations, and (4) the date when full compliance wi!! be achieved. Your response should be
submitted under oath or affirmation and may reference or include previous docketed
correspondence, if the correspondence adequately addresses the required response. If an
j
adequate response is not received within the time specified or an extension of time has not
been granted by the NRC, the NRC will proceed with its enforcement decision or schedule a
predecisional enforcement conference.
In addition, please be advised that the number and characterization of apparent violations
described in the enclosed inspection report may change as a result of further NRC review. You
will be advised by separate correspondence of the results of our deliberations on this matter.

In accordance with 10 CFR 2.790 of the NRC's " Rules of Practice," a copy of this letter, its
enclosure, and your response (if you choose to provide one) will be placed in the NRC Public
Document Room (PDR). To the extent possible, your response should not include any personal
privacy, proprietary, or safeguards information so that it can be placed in the PDR without
redaction.
