Dear Mr. Withers:
This is in response to your letter of March 12, 1982, concerning the accept-ability of the Corbin Number 436 or 437 combination padlock for protecting Safeguards Infonnation.
The staff is not familiar with the nomenclature of the 436 or 437 Corbin padlock; however, whenever combination padlocks are used in response to the requirements of 10 CFR 73.2(mm) and 73.21(d)(2) they should meet the criteria of Regulatory Guide 5.12. " General Use of Locks in the Protection and Control of Facilities and Special Nuclear flaterial". Section C.2. of this guide states that padlocks should meet Federal Specification FF-P-110F, " Padlock, Changeable Combination (Resistant to Opening by Manipulation and Surrepti-tious Attack)".
Sincerely, Robert A. Clark, Chief Operating Reactors Branch #3 Division of Licensing Office of Nuclear Reactor Regulation
