WATTS BAR NUCLEAR PLANT, UNIT 2-CORRECTION TO AMENDMENT NO. 30 TO FACILITY OPERATING LICENSE NPF-96 REGARDING USE OF OPTIMIZED ZIRLO' FUEL ROD CLADDING (EPID L-2018-LLA-0197)

Dear Mr. Barstow:

On May 22, 2019, the U.S. Nuclear Regulatory Commission (NRC or Commission) issued Amendment No. 27 to Facility Operating License No. NPF-96 for the Watts Bar Nuclear Plant (WBN), Unit 2 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML18347B330). Amendment No. 27 revised WBN, Unit 2 Technical Specification (TS) 4.2.1, "Fuel Assemblies," to authorize the irradiation of up to 1,792 tritium producing burnable absorber rods (TPBARs).

On July 25, 2019, the Commission issued Amendment No. 30 to Facility Operating License No. NPF-96 for the Watts Bar Nuclear Plant, Unit 2 (ADAMS Accession No. ML19112A004).

Amendment No. 30 also revised TS 4.2.1 to permit the use of Optimized ZIRLO' fuel rod cladding material. When the NRC staff issued Amendment No. 30, it erroneously did not include the wording regarding TPBARS from Amendment No. 27 on TS page 4.0-1.

The NRC staff concludes that the error was introduced during the preparation of Amendment No. 30. The proposed correction does not change any of the conclusions in the safety evaluation associated with Amendment No. 30 and does not affect the associated notice to the public. Enclosed, please find corrected WBN, Unit 2 TS page 4.0-1.

Sincerely,

/RA/

Kimberly J. Green, Senior Project Manager Plant Licensing Branch 11-2 Division of Operating Reactor Licensing Office of Nuclear Reactor Regulation Docket No. 50-391

Design Features 4.0 4.0 DESIGN FEATURES 4.1 Site 4.1.1 Site and Exclusion Area Boundaries The site and exclusion area boundaries shall be as shown in Figure 4.1-1.

4.1.2 Low Population Zone (LPZ)

The LPZ shall be as shown in Figure 4.1-2 (within the 3-mile circle).

4.2 Reactor Core 4.2.1 Fuel Assemblies The reactor shall contain 193 fuel assemblies. Each assembly shall consist of a matrix of ZIRLO or Optimized ZIRLO' clad fuel rods with an initial composition of natural or slightly enriched uranium dioxide (U02) as fuel material. Limited substitutions of zirconium alloy or stainless steel filler rods for fuel rods, in accordance with approved applications of fuel rod configurations, may be used.

Fuel assemblies shall be limited to those fuel designs that have been analyzed with applicable NRC staff approved codes and methods and shown by tests or analyses to comply with all fuel safety design bases. A limited number of lead test assemblies that have not completed representative testing may be placed in nonlimiting core regions. For Unit 2, Watts Bar is authorized to place a maximum of 1792 Tritium Producing Burnable Absorber Rods into the reactor in an operating cycle.

4.2.2 Control Rod Assemblies The reactor core shall contain 57 control rod assemblies. The control material shall be silver indium cadmium as approved by the NRC.
