ses of related systems and that a failure or malfunction of the system could not adversely affect essential systems or components. The specific areas of review are as follows: 1. Review of the seismic design classification of the pressurizer relief tank and its supporting systems. 2. Review of the quality standards to which the tank and its supporting systems will be designed, fabricated, erected, and tested. 3. Review of the design measures taken to prevent system performance degradation that falls below acceptable levels as a result of failures of other nearby systems or as a result of a tank failure during an anticipated abnormal occurrence. 4. Review of the steam condensing capacity of the tank compared to the largest anticipated plant step load decrease. 5. Review of the instrumentation provided to measure and indicate pressurizer relief tank pressure, temperature, and liquid level and to signal the operator in the event of abnormal parameters. 6. Review of the tank rupture disk relief capacity compared to the capacity of the pressurizer relief and safety valves. 7. Inspections, Tests, Analyses, and Acceptance Criteria (ITAAC). For design certification (DC) and combined license (COL) reviews, the staff reviews the applicant's proposed ITAAC associated with the structures, systems, and components (SSCs) related to this Standard Review Plan (SRP) section in accordance with SRP Section 14.3, "Inspections, Tests, Analyses, and Acceptance Criteria." The staff recognizes that the review of ITAAC cannot be completed until after the rest of this portion of the application has been reviewed against acceptance criteria contained in this SRP section. Furthermore, the staff reviews the ITAAC to ensure that all SSCs in this area of review are identified and addressed as appropriate in accordance with SRP Section 14.3. 8. COL Action Items and Certification Requirements and Restrictions. For a DC application, the review will also address COL action items and requirements and
