Dear all,

Are the standard ANSI/ASME N45.2 and its daughters (N45.2.6 and N45.2.23) in force? If they are obsolete, which is the official document that supersedes these standards? Where are the references about this change?

Thanks in advance for your help.

It is in force if referenced in the QA program, and will depend on the whether a commitment to the governing Regulatory Authority exists to implement the N45.2 standard as described in the QA Program..

Please read Appendix A of Revision 4 to Regulatory Guide 1.28 issued 06/2010 by the NRC found at the link below:
http://adamswebsearch2.nrc.gov/idmws/Vi ... L100160003

Keep this in mind.....The NRC withdrew several Regulatory Guides related to QA over the years. But. the withdrawal of a Regulatory Guide does not alter any prior or existing licensee commitments based on the use of a withdrawn Regulatory Guide. Licensees with prior or existing commitments to a withdrawn standard(s) may continue to implement those provisions or revise their commitments to adopt an acceptable version of the ASME NQA-1 standard
