60 should be explained and justified. 17.6-4 Revision 1 - August 2007 Note 2: At the time of the review, the NRC-endorsed version of the industry guidance on implementation of 50.65(a)(4) may still be contained in the February 22, 2000, revision to Section 11 of NUMARC 93-01, which was endorsed by RG 1.182. This is the effective guidance until the NRC endorses a later revision of NUMARC 93-01 (later than Revision 2) that incorporates this guidance through a later revision of RG 1.160 (later than Revision 2) which will supersede RG 1.182. RG 1.182 will then be withdrawn.
