Ms. Malissa Knott Security Manager Constellation Energy Generation, LLC Braidwood Station 35100 S. Rt. 53, Suite 84 Braceville, IL 60407

SUBJECT:

RESPONSE TO FORMAL DISAGREEMENT WITH ADVERSARY CHARACTERISTICS, ATTRIBUTES, OR TACTICS EMPLOYED OR PREPARED AS PART OF AN NRC-EVALUATED FORCE-ON-FORCE EXERCISE - DISPUTED ITEM 05000456,457/2022-01

Dear Ms. Knott:

The U.S. Nuclear Regulatory Commission (NRC) staff received your letter to the Division of Security Operations (DSO), Security Performance Evaluation Branch titled Formal Disagreement with Adversary Characteristics, Attributes, or Tactics Employed or Prepared as Part of an NRC-Evaluated Force-on-Force Exercise, dated August 8, 2022 (Agencywide Documents Access and Management System (ADAMS) Accession No. ML22234A156), in accordance with Addendum 4 of NRC Inspection Procedure 71130.03 Contingency Response

- Force-on-Force Testing. In your letter you dispute a tactic, technique, or procedure (TTP) within Scenario 1 developed by an NRC Force-on-Force inspection team.

The NRC has carefully reviewed your formal escalation and concluded that the disputed TTPs are approved for continued use within NRC-evaluated exercise scenarios; however, the scenario, as originally written, will not be conducted at Braidwood Station due to several aspects of the scenario needing a further evaluation that could not be completed before the planned exercise week. The inspection team may continue to inspect the attributes of the proposed scenario and enter items, as needed, into the regulatory process, as appropriate.

If you would like to appeal this decision, provide a written response within 3 days from the date of this letter with the basis of your appeal to the Director, DSO.

Sincerely, Jefferson Clark, Branch Chief Security Performance and Evaluation Branch Division of Security Operations Office of Nuclear Security and Incident Response August 23, 2022 Signed by Clark, Jefferson on 08/23/22
