S. 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 any 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 BTP HICB-14, and (3) these plans have been accepted by the NRC staff. C.3.5. 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 50, as described in Section 7.1 and the individual SRP sections applicable to the system under review. Certain review topics need to be considered differently for digital systems. These topics are: • Equipment qualification, including electromagnetic compatibility. • Real-time, deterministic performance. • On-line and periodic test provisions. • Communications independence. • Control of access. Figure 7.0-A-7 outlines the review of these topics. Detailed regulatory bases, material to be reviewed, acceptance criteria, and review processes for each of these topics are contained in Sections 7.1 and 7.9, Appendix 7.1-C, and BTPs HICB-17 and HICB-21. C.3.6. Audit of Software Life Cycle Process Implementation The applicant/licensee's implementation of life cycle activities should be audited to confirm that the planned process is being implemented. Figure 7.0-A-8 provides an overview of the process for auditing the implementation process. Figure 7.0-A-5 identifies the software life cycle process implementation topics that should be considered as candidates for audit. BTP HICB-14, Section
