and b of this SRP section concerning exposures of the total body, skin, and thyroid will be determined based on RAB PERB dose calculations using the ETSB SPLB calculated source term. Conformance with the acceptance criterion given in subsection II.B.1.c of this SRP section concerning the cost-benefit analysis will be determined based on RAB PERB man-Sv (rem) dose 59 calculations in conjunction with ETSB SPLB cost-benefit studies. 2. The ETSB SPLB review of the gaseous waste management systems design capacity will encompass two major areas: a. The capability of the GRS portion of the system to process gaseous wastes in the 60 event of a single major equipment item failure. For nonredundant equipment or components, ETSB SPLB will assume a 3-week downtime every other year (10 days per year average). b. The capability of the GRS portion of the system to process gaseous wastes at 61 design basis fission product levels, i.e., from 1% of the fuel producing power in a PWR or, in a BWR, consistent with a noble gas release rate of 3.7 MBq/sec/MWt (100 µCi/sec/MWt) at 30 minutes delay. 62 ETSB SPLB will review the operational flexibilities designed into the system GRS, e.g., cross connections between subsystems, redundant or reserve 63 processing equipment, and reserve storage capacity. In the evaluation of charcoal delay systems for radioactive gas decay, ETSB SPLB considers the bed dimensions, mass of charcoal, flow rate, temperatures, pressures, humidity, and dynamic adsorption coefficients to calculate the effective holdup times. c. SPLB will review the analyses for the whole body dose at the exclusion area boundary using the assumptions given in BTP ETSB 11-5.64 3. ETSB SPLB compares the quality group classification of piping and equipment in the GRS portion of the gaseous waste management system with the guidelines of 65 Regulatory Guide 1.143. ETSB SPLB also compares the seismic design criteria of DRAFT Rev. 3 - April 1996 11.3-12 equipment and of structures housing
