UNIT 2 (NRC INSPECTION REPORT 05000391 /2014606)

Dear Mr. Skaggs:

On August 11, 2014, the NRC staff completed its performance review of the Watts Bar Nuclear Plant Unit 2 construction project. Our technical staff reviewed inspection results for the period from July 1, 2013 through June 30, 2014. 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.

Overall, Watts Bar Nuclear Plant Unit 2 construction activities were 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. Our inspections indicated that your construction and testing programs were sufficiently implemented to support ongoing construction and testing activities. Management and Quality Assurance oversight effectively monitored and assessed these activities. The corrective action program implementation activities, including initiation, classification, disposition, and trending were deemed satisfactory.

In conclusion, project performance for the most recent quarter, as well as for the previous three quarters of the assessment cycle, was acceptable based on the above inspection conclusions, the fact that all violations were classified as severity level IV or below, and that no substantive cross-cutting issues were identified. Therefore, we do not plan to expand our inspection activities beyond what is specified by Inspection Manual Chapter (IMC) 2517.

The NRC staff spent over 17,900 hours0.0104 days <br />0.25 hours <br />0.00149 weeks <br />3.4245e-4 months <br /> during the 12-month Mid-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 and pre-operational testing activities are completed.

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.

The NRC continues 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 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 http://www.nrc.pov/reading rm/adamshtml (the Public Electronic Reading Room).

Please contact me at (404) 997-4446 with any questions you may have regarding this letter or our planned inspections.

Sincerely, IRN Robert C. Haag, Chief Construction Projects Branch 3 Division of Construction Projects Docket No. 50-391 Construction Permit No: CPPR-92 Enclosure:
