Thanks, Josh Distribute to: Dave Wrona CC: Joel Wiebe, Josh Whitman, Paul Clifford, Reed Anzalone, Kathleen Entz, Kate Suh Dave, By letter dated March 8, 2018, as supplemented by letters dated July 2, 2018, and December 18, 2018, (Agencywide Documents Access and Management System (ADAMS)

Accession Nos. ML18067A431, ML18184A270, and ML18352B117) Exelon Generation Company, LLC (Exelon), the licensee, requested an amendment to the Byron Station, Unit 2, operating license that would allow accident tolerant fuel (ATF) lead test assemblies (LTAs) to be utilized at the plant. The proposed amendment would insert a license condition permitting the use of two such LTAs in Byron Unit 2 during cycles 22, 23, and 24.

The December 18 supplement identifies a transient analyzed in the UFSAR during which the LTAs may be the limiting bundles in the core. The NRC performed a regulatory audit in accordance with the Nuclear Reactor Regulation (NRR) Office Instruction LIC

-111,"Regulatory Audits," to better understand these calculations and in order to expedite the review of this supplement, given the short time available before the refueling outage.

Attached is the report for this audit.
