eatures and other auxiliary features systems, the staff concludes that the design of the safe shutdown systems is compatible with the functional requirements of auxiliary supporting features and other auxiliary features systems. In addition, to the extent that the review is not discussed in other SER sections, the findings will summarize the staff’s evaluation of the ITAAC, including design acceptance criteria, as applicable. 2. Note: the following finding applies only to systems involving digital computer-based components. Based on the review of software development plans and the inspections of the computer development process and design outputs, the staff concludes that the computer systems meet the guidance of Regulatory Guide 1.152. Therefore, the special characteristics of computer systems have been adequately addressed, and the staff finds that the computer-based safe shutdown systems satisfy the requirements of GDC 1. 7.4-10 Revision 5 - March 2007 3. For DC and COL reviews, the findings will also summarize the staff’s evaluation of requirements and restrictions (e.g., interface requirements and site parameters) and COL action items relevant to this SRP section. 4. Note: the following conclusion is applicable to all applications. The conclusions noted above for the safe shutdown systems are applicable to all portions of the systems except for the following, for which acceptance is based on prior NRC review and approval as noted [list applicable system or topics and identify references]. 5. In addition, to the extent that the review is not discussed in other SER sections, the findings will summarize the staff's evaluation of the ITAAC, including design acceptance criteria, as applicable. V. IMPLEMENTATION The staff will use this SRP section in performing safety evaluations of DC applications and license applications submitted by applicants pursuant to 10 CFR Part 50 or 10 CFR Part 52. Except when the applicant proposes an acceptable alternative method for
