September 16, 2013 EN 13-035 OFFICE OF ENFORCEMENT NOTIFICATION OF SIGNIFICANT ENFORCEMENT ACTION

Licensee: Carolina Power and Light Company EA-13-129 H. B. Robinson Steam Electric Plant, Unit 2 Docket No.: 50-261

Subject:

ISSUANCE OF FINAL SIGNIFICANCE DETERMINATION AND NOTICE OF VIOLATION This is to inform the Commission that a Notice of Violation (NOV) will be issued on or about September 18, 2013, to Carolina Power and Light Company (licensee) for a violation associated with a White Significance Determination Process finding identified during an inspection of the H.B. Robinson Steam Electric Plant, Unit 2. This White finding, an issue with low to moderate safety significance, will require additional U.S. Nuclear Regulatory Commission (NRC) inspections. The finding involves licensee's failure to perform adequate preventive maintenance on the dedicated shutdown diesel generator (DSDG) cooling system, in accordance with vendor recommendations and as required by licensee procedures and equipment maintenance

requirements. By procedure, the DSDG is identified as the licensee's alternate ac power source during a station blackout for the exposure period.

A NOV is included based on the licensee's failure to have an alternate ac power source with acceptable capability to withstand station blackout for the required durations specified in its coping analysis, as required by 10 CFR 50.63(c)(2). Specifically, during surveillance testing of the DSDG on October 2, 2012, the DSDG automatically shut down on high engine temperature due to a failure of the radiator drive belts. The condition of the drive belts was significantly degraded, due in part to a lack of adequate inspection, maintenance, and/or periodic replacement. Based on the failure of the DSDG and necessary repair time, this degraded condition would have prohibited the DSDG from supplying power to shutdown equipment within one hour following a station blackout and could have rendered the plant unable to meet the durations specified in its coping analysis. In accordance with the NRC Enforcement Policy, the NOV is considered an escalated enforcement action because it is associated with a White finding.

The licensee attended a Regulatory Conference on August 19, 2013, and presented its assessment of the significance of the finding. After reviewing the information developed during the inspection, and the information provided by the licensee, the staff concluded that the finding is appropriately characterized as White.

It should be noted that the licensee has not been specifically informed of the enforcement action. The schedule of issuance and notification is: Mailing of Final Significance Determination September 18, 2013 Telephone Notification of Licensee September 18, 2013 The State of South Carolina will be notified.
