nsures that a means is provided to monitor the release of radioactive materials, giving the plant operator the indications needed to initiate actions when necessary to protect the health and safety of plant personnel and the general public. 11. TMI Action Plan Item III.D.1.1 in NUREG-0737, or 10 CFR 50.34(f)(2)(xxvi) for those applicants subject to 10 CFR 50.34(f), requires a program and provisions for leakage control and detection for systems outside containment that contain (or might contain) source term radioactive materials following an accident. The PSS provides a means for sampling the reactor coolant systems and containment atmosphere to provide the information necessary to assess and control the plant under accident conditions. Because this system draw samples directly from the reactor coolant systems or from the containment atmosphere, it has the potential for containing source term radioactive material during the course of an accident. To prevent unnecessarily high exposures to workers and the public and to maintain control and use of the systems during an accident, a program should be implemented to minimize leakage from this system to as low as practical levels. Meeting the guidance of TMI Action Plan Item III.D.1.1 in NUREG-0737, or 10 CFR 50.34(f)(2)(xxvi) for those applicants subject to 10 CFR 50.34(f), as they relate to the PSS, 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 material from the procedures described below, as may be appropriate for a particular case. 9.3.2-11 Revision 3 - March 2007 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
