Content:
. The capability of the GRS to process gaseous wastes at design-basis fission product levels (i.e., from 1 percent of the fuel-producing power in a PWR or in a BWR, consistent with a noble gas release rate of 3.7 MBq/s per MWt (100 μCi/s per MWt) with a 30-minute delay. C. The operational flexibility designed into the GRS (e.g., cross-connections between subsystems, redundant or reserve processing equipment, and reserve storage capacity, including the use of mobile processing and treatment systems). D. In the evaluation of charcoal delay systems for radioactive gas decay, the bed dimensions, mass of charcoal, flow rate, temperatures, pressures, humidity, and dynamic adsorption coefficients are used to calculate the effective holdup times. E. Types and characteristics of filtration and adsorbent media to treat gaseous process and effluent streams, with removal efficiencies and decontamination factors meeting or exceeding the performance of NRC generic guidance (NUREG-0016 or NUREG-0017 and Regulatory Guide 1.140), standard design certifications, or topical reports, taking into account the expected physical, chemical, and radiological properties of gaseous process and effluent streams. F. Analysis and results demonstrating compliance with BTP 11-5 for doses to any offsite individuals associated with the postulated failure of a waste gas system component or leak. 3. The quality group classification of piping and equipment in the GRS portion of the GWMS is compared to the guidelines of Regulatory Guide 1.143 for gaseous wastes produced during normal operation and anticipated operational occurrences. The seismic design criteria of equipment and of structures housing the GRS is also compared to the design guidance identified in Regulatory Guide 1.143. When applicable, SRP Sections 3.2.1, 3.2.2, 3.3.1, 3.3.2, 3.5.3, 3.7.1 through 3.7.4, 3.8.4, and 3.8.5 will be used to evaluate exceptions. The applicant’s design is reviewed to ensure that it includes adequate provisions
