RESPONSE TO FORMAL DISAGREEMENT WITH ADVERSARY

CHARACTERISTICS, ATTRIBUTES, OR TACTICS EMPLOYED OR

PREPARED AS PART OF A U.S. NUCLEAR REGULATORY COMMISSION

FORCE-ON-FORCE EVALUATED EXERCISE - DISPUTED ITEM 05000458/2016201-01

Dear Mr. Cook:

Thank you for your email dated February 17, 2016. The Division of Security Operations (DSO),

Security Performance Evaluation Branch received a Formal Disagreement with Adversary

Characteristics, Attributes, or Tactics Employed or Prepared as Part of an NRC Force-on-Force

Evaluated Exercise, in accordance with Addendum 4 of U.S. Nuclear Regulatory Commission

(NRC) Inspection Procedure 71130.03 Contingency Response - Force-on-Force Testing.

In your email, you dispute a tactic, technique, or procedure (TTP) within scenario 1 developed

by the 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 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 ability 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, please provide a written response upon receipt of this

letter with the basis for your appeal, to the Deputy Director, DSO.

Sincerely,

/RA/

Daniel Cardenas, Branch Chief (Acting)
