as a limiting condition for operation (with acceptable outage times). The following items should be specifically included: containment spray pumps, additive pumps (if any), additive mixing devices (if any), valves and nozzles, additive quantity and concentration in additive storage tanks, and nitrogen (or other inert gas) pressure in additive storage tanks. b. Periodic inspection and sampling of the contents of additive storage tanks to confirm that the additive quantity and concentrations are Within the limits established by the system design. c. Periodic testing and exercising of the active components of the system and verification that essential piping and passive devices are free of obstructions. Acceptable methods for computing fission product removal rates by the spray system are given in subsection III.4.c, "Fission Product Cleanup Models." While granting credit for containment spray removal of fission products in the calculations of accident doses, the acceptance criteria of containment leakage in SRP Section 6.2.1.1.A and the acceptance criteria of the engineered safety feature atmosphere cleanup systems in SRP Section
