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 05000282/2017201 AND 05000306/2017201

Dear Mr. White,

Thank you for your email sent on March 20, 2017, to the Division of Security Operations (DSO),

Security Performance Evaluation Branch with the attachment Formal Disagreement with Adversary Characteristics, Attributes, or Tactics Employed or Prepared as Part of an NRC-Evaluated Force-on-Force Exercise (safeguards encrypted), in accordance with Addendum 4 of the U.S. Nuclear Regulatory Commission (NRC) Inspection Procedure 71130.03 Contingency Response - Force-on-Force Testing.

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

The NRC has carefully reviewed your formal escalation and concluded that the disputed TTP is approved for use within the NRC-evaluated exercise scenario for the following reasons: (1) it is within the design basis threat; (2) it is supported by available data; (3) it is within your program requirements to provide defense-in-depth; (4) it can be safely performed and controlled; and (5) it provides a credible and realistic challenge to your sites protective strategy.

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,

/RA/

Andrew Pretzello, Deputy Director Division of Security Operations Office of Nuclear Security and Incident Response
