Content:
signals for actuation of systems to control the release of radioactive materials in effluents, but not required to mitigate the consequences of a DBA, are designed, constructed, installed, tested, and maintained on a level commensurate with their intended function. 11.5-21 DRAFT Rev. 4 - April 1996 This appendix sets forth minimum requirements and is not intended to prohibit the implementation of equivalent design codes, standards, or quality assurance measures other than those indicated herein. B. Definitions Radiological Effluent Monitor: A device which removes a representative sample from the effluent stream, detects and quantitatively measures the radioactive materials present in the sample, discharges the sampled medium back to the effluent stream, and transmits the measurement data to a central point. Monitoring System: A system consisting of one or more remote monitors; a centrally located cabinet or console where data from the monitors is received, recorded, and displayed; and the necessary interconnecting cables, power supplies, pumps, motors, alarms, recorders, display panels, relays, and other auxiliary components. C. Design Guidance Design and quality assurance criteria for radiological effluent monitors should be consistent with the design and quality assurance criteria applicable to the systems which are actuated by a signal from the monitors. Monitors providing signals for the actuation of engineered safety feature (ESF) systems should be designed and qualified to the design and quality assurance criteria applicable to ESF systems. Criteria for ESF-related monitors are found in the appropriate sections of the Standard Review Plans under Section Chapter 7. This position does not affect or modify existing criteria for 98 ESF-related systems. Monitors providing signals for the actuation of non-ESF systems should be designed and qualified to the design and quality assurance criteria applicable to the actuated system or to the criteria shown in Table I,
