s requirements and the commitments the applicant/licensee makes regarding software life-cycle activities. Figure 7.0-A-5 of this appendix identifies the software life-cycle planning topics that should be considered for review. These commitments must be consistent with the commitments made for the design criteria and guidance discussed in subsection C.3.1 above. Figure 7.0-A-6 of this appendix outlines the procedures for reviewing software life-cycle process planning. SRP BTP 7-14 describes the detailed regulatory bases and material to be reviewed for evaluating software development life-cycle process planning. SRP BTP 7-14, subsection B.3.1, describes the acceptance criteria for this review. In addition to confirming the acceptability of the applicant/licensee's plans, this review activity should also identify the higher risk activities of the software life-cycle process for subsequent audit by NRC staff. Almost every computer system involves some use of PDS. PDS may be used directly in plant computers or in processes used to develop in-plant software. The applicant/licensee's process for qualification of PDS should be reviewed as part of the evaluation of the development process. For new applications and license amendment applications, review of software life-cycle process plans is confined to changes in the plans if all of the following conditions hold: (1) the applicant/licensee has previously developed a digital I&C safety system under a process acceptable to the staff, (2) the applicant/licensee has made commitments to software development plans similar to those identified in SRP BTP 7-14, and (3) these plans have been accepted by NRC staff. E. Review of Functional Requirements for Individual Systems The functional requirements and commitments for each I&C system must be reviewed against the requirements of 10 CFR Part 50, as described in SRP Section 7.1 and the individual SRP sections applicable to the system under review. Certain review topics need to be
