- The CIM technical report, WCAP 17179, Revision 2 was docketed July 2010 (ML102170259)
- It is a Tier 2* document incorporated by reference (IBR) in the Vogtle 3&4 UFSAR
- WCAP-17179 is currently at Revision 6, April 2016
- August 2016, SNC Vogtle 3&4 submitted a LAR 16-021 (ML16293A033) capturing all the changes since WCAP-17179, Revision 2 into an Appendix 7A in the UFSAR 46 Westinghouse Non-Proprietary Class 3
