SUBJECT: ANNUAL ASSESSMENT LETTER FOR OYSTER CREEK NUCLEAR GENERATING STATION (REPORT 05000219/2016006)
Dear Mr. Hanson:
The U.S. Nuclear Regulatory Commission (NRC) has completed its end-of-cycle performance assessment of Oyster Creek Nuclear Generating Station, reviewing performance indicators (PIs), inspection results, and enforcement actions from January 1, 2016, through December 31, 2016. This letter informs you of the NRC's assessment of your facility during this period and its plans for future inspections at your facility. The NRC concluded that overall performance at your facility preserved public health and safety.
The NRC determined the performance at Oyster Creek Nuclear Generating Station during the most recent quarter was within the Regulatory Response Column of the NRC's Reactor Oversight Process (ROP) Action Matrix in Inspection Manual Chapter (IMC) 0305, "Operating Reactor Assessment Program." This conclusion was based on a single inspection finding having low-to-moderate safety significance (i.e., White) in the Mitigating Systems Cornerstone originating in the first quarter of 2016, and all PIs within the expected range (i.e., Green). The finding was associated with inadequate work instructions to replace emergency diesel generator cooling flexible coupling hoses.
On August 10, 2016, the NRC issued a supplemental inspection report 05000219/2016011 (ADAMS Accession No. ML16228A053)1, which stated that your actions to address the performance issue(s) were acceptable and the finding was closed. However, as explained in the cover letter, the finding remained in the NRC's assessment program until January 1, 2017. As of January 1, 2017, Oyster Creek Nuclear Generating Station transitioned to the Licensee Response Column of the NRC's ROP Action Matrix. Therefore, the NRC plans to conduct ROP baseline inspections at your facility. Although Oyster Creek plant performance transitioned to the Licensee Response Column on January 1, 2017, the NRC has not yet finalized the significance of Apparent Violation (AV)05000219/2016004-01, "E" Electromatic Relief Valve (EMRV) Failure to Stroke Due to Incorrect Reassembly (ML17025A063). The final safety significance determination of this issue may affect the NRC's assessment of plant performance and the enclosed inspection plan. 1 The designation in parentheses refers to an Agencywide Documents Access and Management System (ADAMS) Accession Number. Documents referenced in this letter are publicly available using the Accession Number in ADAMS. The enclosed inspection plan lists the inspections scheduled through December 31, 2018. The NRC provides the inspection plan to allow for the resolution of any scheduling conflicts and personnel availability issues. Routine inspections performed by resident inspectors are not included in the inspection plan. The inspections listed during the last twelve months of the inspection plan are tentative and may be revised. 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 the plan for security-related inspections, which will be sent via separate, non-publicly available correspondence. The NRC will also be performing Temporary Instruction (TI) 192, "Inspection of the Licensee's Interim Compensatory Measures Associated with the Open Phase Condition Design Vulnerabilities in Electric Power Systems," in the first quarter of 2017. On May 27, 2015, the NRC issued one Severity Level IV traditional enforcement violation to Oyster Creek associated with impeding the regulatory process. In accordance with IMC 0305, Section 13.02.b, the NRC will follow up on the violation through Inspection Procedure 92702, "Follow-up on Traditional Enforcement Actions Including Violations, Deviations, Confirmatory Action Letters, Confirmatory Orders, and Alternative Dispute Resolution Confirmatory Orders."
In accordance with Title 10 of the Code of Federal Regulations (10 CFR) 2.390 of the NRC's "Rules of Practice," a copy of this letter will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRC's document system (ADAMS). ADAMS is accessible from the NRC's Website at http://www.nrc.gov/reading-rm/adams.html (the Public Electronic Reading Room). Please contact Silas Kennedy at 610-337-5046 with any questions you have regarding this letter.
Sincerely,/RA/
Michael L. Scott, Director Division of Reactor Projects Docket Nos. 50-219 License Nos. DPR-16
