r, for digital computer-based I&C systems, it may be premature to complete final design details at the DC stage. Waiting until the COL stage to complete the final design of such systems allows the COL applicant/licensee to use the most recent technology for each plant. Therefore, the review of DC applications for digital computer-based I&C systems may be limited to (1) a detailed review at the functional block diagram level, (2) a review of the applicant/licensee's commitment to prescribed limits, parameters, procedures, and attributes for the detailed design process, and (3) ITAAC adequate to demonstrate that the as-built facility conforms to these commitments. SRP Section 14.3.5 provides guidance in judging the completeness of a DC application when the applicant/licensee proposes to wait until the COL stage to complete the final design of digital computer-based I&C systems. III.B OPERATING LICENSE AND COMBINED LICENSE APPLICATIONS For OL and COL applications, normally the NRC will have reviewed the items discussed in Subsection III.A above and issued an SER based on that review. Therefore, under these circumstances the NRC review at the OL and COL stage may be confined to the following items and changes to commitments made at the CP or DC stage. Hardware and Software Requirements, Detailed Design, Fabrication, Test, and Integration Evaluation The hardware and software requirements, detailed design, fabrication, test, and integration evaluation should be based on the following review points: 1. Implementation of development plans (see SRP Appendix 7.0-A for digital computer- based systems). 2. Conformance of design outputs with system requirements (see SRP Sections 7.2 through 7.9 and SRP Appendix 7.0-A). 3. Evidence of design process characteristics in design outputs (see SRP Appendix 7.0-A for digital computer-based systems). 7.0-9 Revision 6 - May 2010 4. Description and evaluation of the results of the applicant/licensee's research and development to
