Content:
QA criteria for radiological effluent monitors should be consistent with the design and QA criteria applicable to the systems actuated by a signal from the monitors. Monitors providing signals for the actuation of ESF systems should be designed and qualified to the design and QA criteria applicable to ESF systems. Criteria for ESF-related monitors are found in the appropriate sections of SRP Chapter 7. This position does not affect or modify existing criteria for ESF-related systems. Monitors providing signals for the actuation of non-engineered safety feature systems should be designed and qualified to the design and QA criteria applicable to the actuated system or to the criteria shown in Table 1 of this appendix and guidance of this SRP section. 4. Implementation This section provides information to applicants and licensees regarding the staff’s plans for using this appendix. Except in those cases in which the applicant proposes an alternate method for complying with specified portions of the Commission’s regulations, the criteria described herein will be used to evaluate applications for construction permits, operating licenses, and applications for standard DCs and COLs. These criteria do not apply to operating plants with established licensing basis on the above considerations. 11.5-63 Revision 6 – January 2016 APPENDIX 11.5-A TABLE 1 Design Guidance for Radiological Effluent Monitors (Instrumentation Installed in Light-Water-Cooled Nuclear Power Plants) Category Design Criteria Quality Assurance Criteria, and Quality Group and Safety Classifications Effluent radiological monitoring instrumentation providing a signal for the actuation of a system used to control or reduce releases of radioactive materials in effluents within limits specified in plant RETS/SREC. Provisions may be used in protecting nonradioactive systems from being contaminated by bypasses and backflows across systems. (Not required to initiate actuation for an ESF system. For
