WEC CIM TR WCAP-17179-P
- NRC essentially reviewed Revision 6 as stated in LTR Section 6.2.1.1:
The CIM design is documented in the technical report WCAP-17179-P, AP1000 Component Interface Module Technical Report, Reference 8. Westinghouse has docketed a previous revision 2 of WCAP-17179-P (see ML102170259 for non-proprietary version) for NRC review as part of the 10 CFR 52 AP1000 Design Certification process. It is a Tier 2* document incorporated by reference (IBR) in the Vogtle 3&4 UFSAR. A[s] shown in the references, WCAP-17179-P is currently at Revision 6. Since the release of Revision 6, Vogtle 3&4 submitted LAR 16-021 (ML16293A033) capturing all the changes since WCAP-17179-P, Revision 2, in a UFSAR Appendix 7A.
- Vogtle LAR 16-01, which the NRC reviewed and approved, included all changes to WCAP-17179-P including Revision 6, in the UFSAR Appendix 7A (LAR Enclosure 1P).

CIM Configuration Differences between AP1000 and LGS PPS
- Although the CIM was developed initially for the AP1000 PMS, the design is generic as a priority module.
- The AP1000 CIM is exactly the same component as the LGS CIM with no configuration changes.
- An AP1000 CIM can be swapped with an LGS PPS CIM without any configuration changes
- The application of the CIM generic component for the LGS PPS is described in LTR Section 3.2.5
- CIM X-Port (SRNC) connects to the PPS just like it connects to the AP1000 PMS
- CIM Y-port connects to the DCS for manual control and component feedback in exactly the same way as the AP1000 PLS
- CIM Z-port connects to the DPS [DAS] for LGS PPS the same way as ADS Blocker is for PMS. AP1000 DAS does not go through [bypasses] the CIM.
- Only AP1000 licensing precedence being credited is the safety development process for the CIM and not the application of the CIM.

CIM ISG-04 Compliance
- WCAP-17179-P describes the CIM internal design including communication for the three ports. These design descriptions are unchanged since the CIM is unchanged from AP1000.
- The 20 positions in ISG-04 Section 1 are very detailed in criteria for communications (e.g., fixed memory locations, etc.).
- WCAP-17179-P provides an ISG-04 compliance to these 20 positions. Since the internal design of the CIM is unchanged, many of these dispositions are the same regardless of the external interface.
- When a position is unique to PPS, this is explained in the LTR Section 3.2.21 ISG-04 table.
- ISG-04 Sections 2 & 3 compliance are in LTR Section 3.2.5 and do not refer to WCAP-17179-P WAAP-12503, Rev. 0 5
