Content:
o the areas of review addressed by this SRP section is discussed in the following paragraphs: 1. GDC 41 establishes the design requirements for containment atmosphere cleanup systems which function to reduce the concentration and quality of fission products released to the environment following postulated accidents. The radiological consequences of accidents in Chapter 15 of the SAR depend on the quantity and quality of the fission products released from containment. The containment spray system may be relied upon to provide an effective means for removal of iodine and other fission products released to the containment atmosphere following a design-basis accident. Fission product iodine is removed and retained by the spray solution and is unavailable for release to the environment. Compliance with GDC 41 ensures that the containment spray system will accomplish the fission product removal function assumed in the Chapter 15 radiological consequence calculations. 2. GDC 42 establishes the requirements for the inspection of containment atmosphere cleanup systems. The inspection of important components such as pumps, valves, tanks, and flow paths ensures the integrity and capability of the system. The containment spray system may be credited with providing fission product removal and retention following design-basis accidents. Proper operation of the containment spray system depends on the integrity of system pumps, valves, spray nozzles, chemical additive systems, and flow paths. Periodic inspection ensures that these components are capable of performing their design function in the event of an accident. 3. GDC 43 establishes the requirement that the design of the containment atmosphere cleanup systems allow appropriate periodic functional testing. The capability of the containment spray system to perform the function of fission product removal depends on the operability of the pumps, valves, nozzles, chemical additive systems, actuation circuitry, and power supplies
