SUBJECT: ARKANSAS NUCLEAR ONE, UNITS 1 AND 2 RESPONSE TO NOTICE OF VIOLATION (NRC INSPECTION REPORT 05000313/2014008 AND 05000368/2014008)

Dear Mr. Browning:

On June 23, 2014, the NRC cited failure to accomplish a move of the Unit 1 main turbine generator stator in accordance with documented instructions and procedures as required by 10 CFR 50, Appendix B, Criterion VInstructions, Procedures, and Drawings. The Notice of Violation, enclosed with Inspection Report 05000313/2014008 and 05000368/2014008 (ML14174A832), required you to respond in writing within 30 days. You responded by letter dated July 18, 2014 (ML14199A412). We have reviewed your response and find that it meets the requirements of 10 CFR 2.201. We will review your corrective actions during a future inspection. We also noted that your response included a discussion regarding safety-related equipment not being damaged by the March 31, 2013, Unit 1 stator drop event. It is acknowledged that no safety-related components were damaged by the crane collapse and resulting drop of the main turbine generator stator. The statement contained in our June 23, 2014, letter that safety-related equipment was affected by the event was based on the damage caused by the event affecting safety-related systems such as: (1) the loss of the operating decay heat removal pump in Unit 1 resulting in a temporary loss of shutdown cooling to the reactor; and (2) a loss of one Unit 2 safety-related electrical bus that had to be re-energized by a standby emergency diesel generator. In accordance with 10 CFR 2.390 of the NRC's "Rules of Practice," a copy of this letter will be made available electronically for public inspection in the NRC Public Document Room or from the NRCs Agencywide Documents Access Management System (ADAMS), which is accessible from the NRC Web site at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
