Content:
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 for the system. The periodic functional testing of the containment | spray system and its components provides assurance of system operability and the | capability to fulfill the design function of fission product removal in the event of a design- | basis accident. | III. REVIEW PROCEDURES The reviewer selects and emphasizes aspects covered by this SRP section as appropriate for a particular plant. The judgment of which areas need to be given attention and emphasis in the review is based on whether the material presented is similar to material recently reviewed for other plants and whether items of special safety significance are involved. The reviewer determines whether the containment spray system is used for fission product removal purposes. SAR Chapter 15 should be reviewed to establish whether the accident dose evaluations assume a fission product removal function for the containment spray system. If the containment spray system is not used for mitigating radiological dose, no further review is required under this SRP section. If the containment spray system is used for mitigation of radiological doses, then the review of the fission product removal function of the containment spray system follows the procedure and carries out the review responsibilities outlined below. 1. System Design Review of the system design includes an examination of the components and design features necessary to carry out the fission product scrubbing function, including: a. Spray Solution Chemistry (primary reviewer) The reviewer identifies the forms of iodine for which spray removal credit is claimed in the accident analyses (SAR Chapter 15). Containment spray systems may be designed for removal of iodine in the elemental form, in the form of organic compounds, and in the particulate form. The
