007 These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the applicant’s evaluation of how the proposed alternatives provide an acceptable method of complying with the relevant NRC requirements identified in Subsection II. 1. In the review of the PSS, the primary review organization and the organization responsible for the review of chemical engineering issues review the process sampling points as shown on piping and instrumentation diagrams, and compare the list of process sampling points contained in the safety analysis report with the sampling points identified in Item 1 of the SRP Acceptance Criteria, above, to ensure that the required process sampling points have been provided. 2. The primary review organization and the organization responsible for the review of radiation protection compare the capability of the system to obtain representative samples of process fluids and the locations of sampling points with the guidelines for obtaining representative samples of fluids contained in Regulatory Position C.6 of RG 1.21 and with the principles for obtaining representative samples of gases contained in ANSI/HPS N13.1-1999. 3. The primary review organization and the organization responsible for the review of radiation protection verify that provisions made for purging sampling lines and for reducing plateout in sample lines (e.g., heat tracing) conform with the guidelines of Regulatory Position C.7 in RG 1.21. 4. The primary review organization, the organization responsible for the review of systems associated with the balance of plant, and the organization responsible for the review of radiation protection verify that provisions have been made to purge and drain sample streams back to the system of origin or to an appropriate waste treatment system to keep radiation exposures at ALARA levels, and that these provisions conform with the guidelines of Regulatory Positions
