SUBJECT:

DAVIS-BESSE NUCLEAR POWER STATIONNRC INSPECTION REPORT 05000346/2018010 AND PRELIMINARY WHITE FINDING

Dear Mr. Bezilla:

On January 31, 2018, the U.S. Nuclear Regulatory Commission (NRC) completed an inspection at your Davis-Besse Nuclear Power Station and the NRC inspectors discussed the results of this inspection with you and other members of your staff. The results of this inspection are documented in the enclosed report.

Section 4OA2 of the enclosed report documents a finding with an associated violation that the NRC has preliminarily determined to be White with low-to-moderate safety significance. This finding involved a performance deficiency and the apparent failure of the licensee to provide appropriate instructions to maintain an adequate amount of oil in an auxiliary feedwater turbine bearing oil sumps, resulting in the failure of the auxiliary feedwater pump. We assessed the significance of the finding using the significance determination process (SDP) and readily available information. The evaluation included reviewing and assessing the ability of installed FLEX equipment to mitigate the potential impact on secondary heat removal due to the finding.

This apparent violation and its associated cross-cutting aspect association was originally discussed with you and your staff and presented in NRCs Davis-Besse Inspection Report 05000346/2017004 dated February 14, 2018 (ADAMS Accession Number ML18045A076).

We are considering escalated enforcement for the apparent violation consistent with our Enforcement Policy, which can be found at http://www.nrc.gov/about-nrc/regulatory/enforcement/enforce-pol.html. Because we have not made a final determination, no notice of violation is being issued at this time. Please be aware that further NRC review may prompt us to modify the characterization of the apparent violation.

We intend to issue our final significance determination and enforcement decision, in writing, within 90 days from the date of this letter. The NRCs significance determination process (SDP)

is designed to encourage an open dialogue between your staff and the NRC; however, neither the dialogue nor the written information you provide should affect the timeliness of our final determination.

Before we make a final decision, you may choose to communicate your position on the facts and assumptions used to arrive at the finding and assess its significance by either (1) attending and presenting at a regulatory conference or (2) submitting your position in writing. The focus of a regulatory conference is to discuss the significance of the finding. Written responses should reference the inspection report number and enforcement action number associated with this letter in the subject line.

If you request a regulatory conference, it should be held within 40 days of your receipt of this letter. Please provide information you would like us to consider or discuss with you at least 10 days prior to any scheduled conference. If you choose to attend a regulatory conference, it will be open for public observation. If you decide to submit only a written response, it should be sent to the NRC within 40 days of your receipt of this letter. If you choose not to request a regulatory conference or to submit a written response, you will not be allowed to appeal the NRCs final significance determination.

Please contact Jamnes Cameron at 630-829-9833, and in writing, within 10 days from the issue date of this letter to notify the NRC of your intentions. If we have not heard from you within 10 days, we will continue with our significance determination and enforcement decision.

This letter, its enclosure, and your response (if any) will be made available for public inspection and copying at http://www.nrc.gov/reading-rm/adams.html and at the NRC Public Document Room in accordance with 10 CFR 2.390, Public Inspections, Exemptions, Requests for Withholding.

Sincerely,

/RA Julio Lara Acting for/
