nd 3) technical specification limits for halogens (I-131 dose equivalent) and noble gases (Xe-133 dose equivalent), as defined in plant-specific TS. D. Types and characteristics of filtration systems, ion-exchange resins, and adsorbent media (activated charcoal), and use of other treatment technologies, as described in the application, to treat process and effluent streams with removal efficiencies, decontamination factors, and holdup times meeting or exceeding the performance criteria of RG 1.112 and guidance of NUREG-0016 or NUREG-0017, as modified to reflect specific design features, and DC/COL-ISG-05 in the use of GALE86. The above information may be drawn from standard DCs, or topical reports, taking into account the expected processing flow rates and volumes, and the physical, chemical, and radiological properties of liquid process and effluent streams. E. Justification for automatic control features and placement of isolation valves and radiation detectors on process piping and effluent discharge lines to ensure the 11.2-23 Draft Revision 5 – August 2014 timely closure of such valves upon the detection of elevated radioactivity levels, and, if part of the design, controls in monitoring deviations of in-plant dilution flow rates in terminating releases or isolating process flows when deviations exceed preset limits. Other considerations may include determining whether system logic demands that a valve or damper should fail in the closed position in protecting the system from further contamination, terminating releases to the environment, or diverting process streams or effluents to appropriate treatment subsystems. Acceptable guidance is presented in SRP Section 11.5 and ANS N42.18-2004. The average input flow rates and volumes are compared with the design flows to determine the fraction of time individual subsystems must be online to process normal waste input volumes. The review considers the operational flexibility designed into the system (i.e.,
