UNITED STATES NUCLEAR REGULATORY COMMISSION REGION I 2100 RENAISSANCE BLVD.

SUBJECT:

MID-CYCLE ASSESSMENT LETTER FOR OYSTER CREEK NUCLEAR GENERATING STATION (REPORT 05000219/2016005)

Dear Mr. Hanson:

On August 9, 2016, the U.S. Nuclear Regulatory Commission (NRC) completed its mid-cycle performance review of Oyster Creek Nuclear Generating Station. The NRC reviewed the most recent quarterly performance indicators (PIs) in addition to inspection results and enforcement actions from July 1, 2015, through June 30, 2016. This letter informs you of the NRCs assessment of your facility during this period and its plans for future inspections at your facility.

The NRC determined the performance at Oyster Creek Nuclear Generating Station during the most recent quarter was within the Regulatory Response Column of the NRCs Reactor Oversight Process (ROP) Action Matrix because one finding of White significance, associated with the Mitigating Systems cornerstone, was identified in the first quarter 2016 integrated inspection report (ADAMS Accession No. ML16132A436). The finding was associated with inadequate work instruction to replace the Emergency Diesel Generator (EDG) cooling flexible coupling hoses as specified by Exelons procedure and vendor information. The final significance determination and follow-up assessment letter for this finding was issued on July 6, 2016 (ML16188A014). In that letter we informed you that Oyster Creek had transitioned to the Regulatory Response Column of the ROP Action Matrix retroactive to the first quarter of 2016. On June 14, 2016, your staff notified the NRC of your readiness for the NRC to conduct a supplemental inspection to review the actions taken to address the performance issues.

Therefore, in addition to ROP baseline inspections, the NRC conducted a supplemental inspection in accordance with Inspection Procedure (IP) 95001, Supplemental Inspection for One or Two White Inputs in a Strategic Performance Area, during the week of July 25, 2016.

The objectives of the 95001 inspection were to provide assurance that the root cause and contributing causes of risk significant performance issues were understood, the extent of condition and extent of cause were understood, and the corrective actions were sufficient to address the root and contributing causes and prevent recurrence. The NRC determined that Exelon met the objectives of IP 95001. The NRC closed the White finding and notified you of the results of this inspection via follow-up assessment letter and Inspection Report 05000219/2016011 dated August 10, 2016, (ML16228A053) which also informed Exelon that Oyster Creek will remain in the Regulatory Response Column for a full four quarters following the identification of the White finding in January 2016.

B. Hanson The enclosed inspection plan lists the inspections scheduled through June 30, 2018. Routine inspections performed by resident inspectors are not included in the inspection plan. The inspections listed during the last half of the inspection period in the inspection plan are tentative and may be revised at the end-of-cycle performance review. The NRC provides the inspection plan to allow for the resolution of any scheduling conflicts and personnel availability issues.

The NRC will contact you as soon as possible to discuss changes to the inspection plan should circumstances warrant any changes. This inspection plan does not include security related inspections, which will be sent via separate, non-publicly available correspondence.

In response to the accident at Fukushima, the Commission issued Order EA-12-049, Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events, and Order EA-12-051, Order Modifying Licenses with Regard to Reliable Spent Fuel Pool Instrumentation. The NRC conducted audits of licensee efforts towards compliance with these Orders, and the information gathered will aid staff in development of the ultimate Final Safety Evaluation for Oyster Creek. After the NRC staff receives the Final Compliance letter for the site, the Safety Evaluation will be issued. Then, the NRC staff will confirm through inspections the full implementation of the orders mentioned above by performing Temporary Instruction 2515-191, Inspection of the Implementation of Mitigation Strategies and Spent Fuel Pool Instrumentation Orders and Emergency Preparedness Communication/Staffing/Multi-Unit Dose Assessment Plans.

In Staff Requirements Memorandum - SECY 16-0009, Recommendations Resulting from the Integrated Prioritization and Re-Baselining of Agency Activities, (ADAMS Accession #

ML16104A158) the Commission approved the NRC staff recommendation to discontinue the formal mid-cycle assessment process beginning in calendar year 2017. This will be the final mid-cycle assessment letter. The staff will continue to conduct assessment reviews and communicate changes in the assessment of licensee performance quarterly, and will also issue end-of-cycle assessment letters.

In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390 of the NRCs Rules of Practice, a copy of this letter will be available electronically for public inspection in the NRCs Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). ADAMS is accessible from the NRCs Website at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room).
