l specifications. 6. The organization responsible for quality assurance performs the reviews of design, construction, and operations phase quality assurance programs under SRP Chapter 17. In addition, while conducting regulatory audits in accordance with Office Instruction NRR-LIC-111 or NRO-REG-108, “Regulatory Audits,” the technical staff may identify quality-related issues. If this occurs, the technical staff should contact the organization responsible for quality assurance to determine if an inspection should be conducted. The specific acceptance criteria and review procedures are contained in the referenced SRP sections. II. ACCEPTANCE CRITERIA Requirements Because the pressurizer relief tank system is inside the containment, possibly in close proximity to essential systems and components, acceptance is based on the ability of the system, in the event of a failure or malfunction, to avoid an adverse effect on the equipment necessary to bring the plant to a safe shutdown condition, prevent accidents, or mitigate the consequences of an accident. Acceptance criteria are based on meeting the relevant requirements of the following Commission regulations: 1. General Design Criterion (GDC) 2, as it relates to the protection of essential systems from the effects of earthquakes. Acceptance is based on meeting the guidelines in Position C.2 of Regulatory Guide (RG) 1.29 regarding the location of the tank in relation to other plant systems (the design of the tank system should be such that the plant 5.4.11-4 Revision 4 - May 2010 safety-related systems would continue to perform their safety functions in the event of a tank failure) and in Position C.3 regarding the extension of seismic Category I boundaries. 2. GDC 4, as it relates to a failure of the system that results in missiles or adverse environmental conditions that could produce unacceptable damage to safety-related systems or components. 3.
