UNITED STATES NUCLEAR REGULATORY COMMISSION WASHINGTON, D.C. 20555-0001 August28, 2014 APPLICANT: Tennessee Valley Authority FACILITY: Watts Bar Nuclear Power Plant, Unit 2

SUBJECT:

SUMMARY

OF JULY 22, 2014, MEETING WITH TENNESSEE VALLEY AUTHORITY REGARDING THE WATTS BAR NUCLEAR PLANT, UNIT 2 OPERATING LICENSE APPLICATION On July 22, 2014, a Category 1 public meeting was held between the U.S. Nuclear Regulatory Commission (NRC) and representatives of the Tennessee Valley Authority (TVA) at the NRC Headquarters 11555 Rockville Pike, Rockville, Maryland. The purpose of this meeting was for TVA to present the status of construction and licensing efforts for the Watts Bar Nuclear Plant (WBN), Unit 2 project. The meeting notice and agenda, dated July 16, 2014, is available in the Agencywide Documents Access and Management System (ADAMS) at Accession No. ML14167A244. A list of attendees is enclosed.

TVA made a presentation to the NRC staff, which is included as an enclosure to this summary.

This presentation covered the following topics: WBN Unit 2 construction status; the overall project timeline; project risks; the status of licensing related documents; hydrology; TVA's Fukushima Response as it relates to WBN Unit 2; Fire Protection at WBN Unit 2; TVA's strategy to address questions on Title 10 of the Code of Federal Regulations Appendix A to Part 50 General Design Criterion 5; the substantially complete process and related notifications; as well as public outreach. Also during their presentation TVA stated that while the schedule identifies license issuance and fuel load in June of 2015, TVA's more aggressive schedule had originally planned for the license to be issued and fuel to be loaded in February of 2015. However due to various delays in construction and other licensing issues TVA now believes a date of March 29, 2015 is more appropriate for their internal schedule. TVA noted that a fuel load date of June 2015 would be needed to begin commercial operation by December 2015, which is the date that TVA has commited to the TVA board of directors.

Throughout TVA's presentation the staff asked clarifying questions, especially in regards to the issue of hydrology. The staff made it clear to TVA that at this point in the process of the project, timeliness in submittals, and completeness of submittals is of the utmost importance to ensure the NRC can make as efficient a review as possible. The NRC made it clear that their review will take as much time as necessary to ensure the safety of the public.

No regulatory decisions were made at this meeting.

A few members of the public were in attendance at this meeting and asked several questions of the NRC. A few of the questions were related to hydrology issues at the Watts Bar site.

Members of the public expressed concern at TVA identifying this issue as a moderate risk despite requiring substantial changes to be made by the end of August, TVA voluntarily

responded to these comments by stating that the schedule risks may change but they are doing their best to meet the current dates. Another question from the public related to how the issues related to Fukushima were resolved at the WBN Unit 2 site and a better understanding of the staff's priority list associated with seismic review that was released in May 2014 (ML14111A147). The staff explained that the current hydrology issues were for design basis type events, whereas Fukushima is recognized as a beyond design basis event, additionally the staff clarified that the priority list had to do with resource availability and staff availability, rather than with risks associated with seismic events. For these reasons WBN Unit 2 is following similar implementation milestones related to Fuksuhima as operating plants in accordance with the Orders that were issued. Additional questions were asked about how TVA planned on addressing any effects from the staff's rulemaking effort on Waste Confidence and fuel storage in general. TVA voluntarily responded that the rulemaking is out of their control, and as such they can only react to the final result. Finally, some additional concerns were raised by a member of the public on dam safety referencing the Kingston Coal Ash dam failure, which occurred even when the dam was constructed and inspected according to certain standards.

fi!1 GDC-5

  • Sharing of Structures, systems, and components (SSC). SSCs important to safety shall not be shared among nuclear power units unless it can be shown that such sharing will not significantly impair their ability to perform their safety functions, including, in the event of an accident in one unit, an orderly shutdown and cooldown of the remaining units.
  • Component Cooling System (CCS) is shared between two WBN units
  • WBN 1/2 is hot standby design plant (mode 3). Considered safe to remain in Mode 3 until decay heat allows further cooldown.
  • Limiting event is LOCA in one unrt and reactor shutdown in other unit with loss of train A power. One 8 train heat exchanger remains to cooldown both units. Flow shared between units.
  • Within system capacity to handle accident unit and cooldown non-accident unit, provided non-accident unit cooldown can be delayed_

Koontz 16

iJ!] GDC-5

  • If non-accident unit is in Mode 1-3, remain in Mode -3 for 48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br /> with cooling by steam generators. (Safe Shutdown)
  • If non-accident unit is in mode 5, prior to venting of RCS (48 hours5.555556e-4 days <br />0.0133 hours <br />7.936508e-5 weeks <br />1.8264e-5 months <br />), allow RCS to return to mode 4 or 3 and steam from steam generators.
  • Technical Specification prohibition TS 3.0.4
