4 NUCLEAR REGULATORY COMMisslON WASHINGTON, D. C. 20555 March 20, 1986 REGULATORY GUIDE DISTRIBUTION LIST (DIVISION 3)

SUBJECT:

ISSUANCE OF REVISION 2 TO REGULATORY GUIDE 3.4 AND WITHDRAWAL OF REGULATORY GUIDE 3.41 With the issuance of Revision 2 to Regulatory Guide 3.4, " Nuclear Criticality Safety in Operations with Fissionable Materials at Fuels and Materials Facilities," the NRC staff is withdrawing Regulatory Guide 3.41,

" Validation of Calculational Methods for Nuclear Criticality Safety."

Revision 2 to Regulatory Guide 3.4 endorses ANSI /ANS-8.1-1983, " Nuclear D

Criticality Safety in Operations with Fissionable Materials Outside Reactors," which is a consolidation of ANSI N16.1-1975/ANS-8.1 (endorsed by Revision 1 of Regulatory Guide 3.4) and ANSI N16.9-1975/ANS-8.ll (endorsed by Regulatory Guide 3.41).

Regulatory Guide 3.41 is therefore obsolete. However, withdrawal of Regulatory Guide 3.41 is in no way intended to alter any prior or existing licensing commitments based on its use.

Regulatory guides may be withdrawn when they are superseded by the Commission's regulations, when equivalent recommendations have been incorporated in applicable approved codes and standards, or when changes in methods and techniques or in the need for specific guidance have made them obsolete.
