UNITED STATES NUCLEAR REGULATORY COMMISSION
REGION II
245 PEACHTREE CENTER AVENUE NE, SUITE 1200 ATLANTA, GEORGIA 30303-1257 February 28, 2014 Mr. Michael Senior Vice President Nuclear Construction Tennessee Vaiiey Authority 6A Lookout Place 1101 Market Street Chattanooga, TN 37402-2801 SUBJECT: END-OF-CYCLE ASSESSMENT LETTER WATTS BAR NUCLEAR PLANT
UNIT 2 (NRC INSPECTION REPORT 05000391/2014601)
Dear Mr. Skaggs:
On February 10, 2014, the U. S. Nuclear Regulatory Commission (NRC) staff completed its performance review of the Watts Bar Nuclear Plant (WBN) Unit 2 construction project. Our technical staff reviewed inspection results for the period from January 1, 2013, through December 31, 2013. The purpose of this letter is to inform you of our assessment of your safety performance during this period and our plans for future inspections at your facility.
During the 2 nd quarter of this assessment period the NRC identified three violations associated with your commercial grade dedication program that were characterized as a Severity Level Ill problem in accordance with the NRCs Enforcement Policy and assessed a $70,000 Civil Penalty. These violations are described in Inspection Report 05000391/201 361 4, dated June 18, 2013 (ADAMS Accession Number ML13169A030). Consistent with the guidance in Inspection Manual Chapter 2517, Watts Bar 2 Construction Inspection Program, which defines a Severity Level Ill violation as a significant performance issue, the NRC increased inspection for WBN Unit 2. Specifically, the NRC performed an additional inspection using the guidance in Inspection Procedure 92702, Follow-up on Traditional Enforcement Actions including Violations, Deviations, Confirmatory Action Letters, Confirmatory Orders and Alternate Dispute Resolution Confirmatory Orders. This inspection, which was completed February 12, 2014, reviewed your corrective actions to these violations to verify that your commercial grade dedication program is in compliance with regulations and that the corrective actions were adequate to prevent recurrence. The results of this inspection will be published in Inspection Report 05000391/2014602, scheduled to be released to the public in April 2014.
During the remainder of the assessment period, with the exception noted above, WBN Unit 2 construction activities were generally conducted in a manner that complied with the Commissions rules and regulations, the conditions of your construction permit, and the Unit 2 regulatory framework commitments. Overall, the corrective action program implementation activities, including initiation, classification, disposition, and trending were deemed satisfactory.
This overall conclusion was based on the results of the annual Problem Identification and Resolution (Pl&R) team inspection, focused sample Pl&R inspections, and the ongoing assessment of your corrective action program as part of routine inspections. No Substantive Cross-Cutting Issues were identified during this period. The NRC staff spent over 13,000 hours0 days <br />0 hours <br />0 weeks <br />0 months <br /> during the 12-month End-of-Cycle Assessment period performing inspections, assessments, public meetings, allegation follow-up, and inspection program support for WBN Unit 2. The NRC staff anticipates this level of effort will increase over the next 12-month assessment cycle as WBN Unit 2 construction activities continue and pre-operational testing is performed on additional safety-related systems.
As a result of reviewing your construction schedule and through interaction with your staff, the enclosed inspection plan contains those projected inspection activities that we have currently identified. Many of the inspections listed in the enclosed inspection plan were scheduled based on information your staff provided to the NRC. This information involved dates for completion of construction activities that would be subject to the corresponding NRC inspections. Therefore, it is crucial that you keep us apprised of any changes to the scheduled completion dates, in order to maintain our inspection plan current. As additional details of your project schedule become available, we will plan other inspections specified in Inspection Manual Chapter 2517. Your staff will be given ample notification of changes to upcoming inspection activities or newly identified inspections as they become finalized in order to allow for the resolution of any scheduling conflicts and personnel availability. Routine inspections performed by the resident staff are not listed on the inspection plan due to their ongoing and continuous nature.
With the start of preoperational testing at WBN Unit 2, the NRC has begun implementation of Inspection Manual Chapter 2513, Light Water Reactor Inspection Program Preoperational
Testing and Operational Preparedness Phase. We have not listed preoperational testing inspections in the enclosed inspection plan due to likelihood that the inspection dates will change as adjustments to your preoperational testing schedule occur.
In addition to the above inspection activities, an NRC audit of licensee efforts towards compliance with Order EA-12-049, Order Modifying Licenses with Regard to Requirements for Mitigation Strategies for Beyond-Design-Basis External Events is ongoing. This audit includes an onsite component in order for the NRC to evaluate mitigating strategies as described in licensee submittals, and to receive and review information relative to associated open items.
This onsite activity will occur in the months prior to a declaration of compliance for the first unit at each site, and will aid staff in development of an ultimate Safety Evaluation for the site.
The onsite component has been scheduled for the week of March 10, 2014. A site-specific audit plan for the visit will be provided in advance to allow sufficient time for preparations.
In accordance with 10 CFR 2.390 of the NRCs Rules of Practice, a copy of this letter and its enclosure will be available electronically for public inspection in the NRC Public Document Room or from the Publicly Available Records (PARS) component of NRCs document system (ADAMS). ADAMS is accessible from the NRC Web site at htto//www.nrc.oov/readino rm!adams.html (the Public Electronic Reading Room). Please contact Robert Haag at (404)
