UNITED STATES NUCLEAR REGULATORY COMMISSION une 16, 2015

SUBJECT:

DAVIS-BESSE NUCLEAR POWER STATION; NRC SUPPLEMENTAL INSPECTION REPORT 05000346/2015404 AND ASSESSMENT FOLLOW-UP LETTER

Dear Mr. Lieb:

On May 21, 2015, the U.S. Nuclear Regulatory Commission (NRC) staff completed a supplemental inspection, at your Davis-Besse Nuclear Power Station. The enclosed inspection report documents the inspection results, which were discussed at the exit meeting, on May 21, 2015, with Mr. D. Saltz and other members of your staff. During this meeting, Messrs. S. Orth and J. Maynen discussed the associated performance deficiency and corrective actions with your staff, which fulfills NRC policy for a regulatory performance meeting.

In accordance with the NRC Reactor Oversight Process (ROP) Action Matrix, this supplemental inspection was performed to follow-up on a performance issue that was identified in the third quarter of 2014. The issue was previously documented and assessed in NRC Inspection Report (IR) 05000346/2014406 and NRC letter dated October 22, 2014. The NRC was informed of your readiness for the inspection on March 20, 2015.

The objectives of this supplemental inspection were to determine whether or not: (1) the root causes and contributing causes for the significant issues were understood; (2) the extent of condition and the extent of cause of the issues were identified; and (3) corrective actions were or will be sufficient to address and preclude repetition of the root and contributing causes.

After reviewing Davis-Besse Nuclear Power Station performance in addressing the Greater-Than-Green finding that was the subject of this inspection, the NRC concluded that your actions met the objectives. Therefore, in accordance with the guidance in Inspection Manual Chapter 0305, Operating Reactor Assessment Program, the Greater-Than-Green finding will only be considered in assessing plant performance for a total of four quarters.

As a result, the NRC determined the performance at Davis-Besse Nuclear Power Station will be in the Licensee Response Column of the ROP Action Matrix as of the start of the third quarter of 2015.

Enclosure contains Sensitive Unclassified Non-Safeguards Information. When separated from enclosure, this transmittal document is decontrolled. No findings were identified during this inspection.
