Content:
ize leakage from these systems to as low as practical levels. Meeting the guidance of TMI Action Plan Item III.D.1.1 as clarified in NUREG-0737, as it relates to the process and post accident sampling systems, enhances safety by minimizing the leakage from these systems and thereby minimizing the potential exposures to workers and the public, and by providing reasonable assurance that excessive leakage will not prevent the use of the systems under accident conditions. III. REVIEW PROCEDURES The reviewer will select and emphasize material from this SRP section, as may be appropriate for a particular case. 1. In the review of the process sampling system, CMEBEMCB compares the list of 43 process sampling points contained in the SAR with the sampling points identified in Subsection II.1, above, to assure that the required process sampling points have been provided. 2. CMEBEMCB compares the capability of the system to obtain representative samples of 44 process fluids and the locations of sampling points with the guidelines for obtaining representative samples of fluids contained in regulatory position C.6 of Regulatory Guide 1.21 (reference 1) and with the principles for obtaining representative samples of gases 45 contained in ANSI N13.1-1969 (reference 3) . 4647 3. CMEBEMCB compares the seismic design and quality group classifications of the PSS 48 and PAS to the classifications of the fluid systems to which the sampling system is connected. DRAFT Rev. 3 - April 1996 9.3.2-12 4. CMEBEMCB reviews the technical specifications for process sampling to determine 49 that the content and intent of the technical specifications are in agreement with the requirements developed as a result of the staff's review.50 5. CMEBEMCB verifies that provisions have been made to limit the potential for reactor 51 coolant loss from the rupture of a sample line and provides Accident Evaluation Branchthe PERB with estimates of RCS fluid losses that would result from sample line 52 rupture. 6.
