ission product removal function, considering conditions that could result in fast as well as slow injection of the spray solution. 2. Testing (secondary reviewer) At the construction permit stage, the containment spray concept and the proposed tests of the system are reviewed to confirm the feasibility of verifying the design functions by appropriate testing. At the operating license stage, the proposed tests of the system and its components are reviewed to verify that the tests will demonstrate that the system, as installed, is capable of performing—within the bounds established in the description and evaluation of the system—all functions essential for effective fission product removal following postulated accidents. 3. Technical Specifications (primary reviewer/secondary reviewer) The technical specifications are reviewed to verify that the system, as designed, is capable of meeting the design requirements and that it remains in a state of readiness whenever the reactor is critical. Rev. 3 - December 2005 6.5.2-10 a. Limiting Conditions for Operation The limiting conditions for operation should require the operability of the containment spray pumps, all associated valves and piping, the appropriate quantity of additives, and any metering pumps or mixing devices. b. Tests Preoperational testing of the system, including the additive storage tanks, pumps (if any), piping, and valves, is required. In particular, the preoperational testing should verify that the system, as installed, is capable of delivering a well-mixed solution containing all additives in concentrations that are within the design margins assumed in the dose analyses of SAR Chapter 15. Periodic testing and exercising of all active components should include the spray pumps, metering pumps (if any), and valves. Confirmation should be made periodically that passive components, such as all essential spray and spray additive piping, and any passive mixing devices are free of obstructions. The contents
