appropriate for a particular case. 1. In the ETSB review of the gaseous waste management systems, the P&IDs and system process flow diagrams are reviewed to determine all sources of gaseous waste, the points of collection of gaseous wastes, the flow paths of gases through the systems, including all bypasses, the treatment pro- vided and the points of release of gaseous effluents to the environment. This information is used to calculate the quantity of radioactive material (noble gases, radioiodine, and particulates) released annually in gaseous effluents during normal operations, including anticipated operational occurrences, using the given parameters, the GALE Code, and the calcula- tional techniques given in HUREG Reports 0016 and 0017. A complete Fortran listing of the GALE computer code is given in these reports. The results of this calculation will be used to determine whether the pro- posed gaseous waste management systems design meets the acceptance criterion of subsection II.B.l.d of this SRP section. Compliance with the accept- ance criteria of subsection II.B.1.a and b of this SRP section concerning exposures of the total body, skin, and thyroid will be determined based on RAO dose calculations using the ETSB calculated source term. Con- formance with the acceptance criterion given in subsection II.B.l.c of this SRP section concerning the cost-benefit analysis will be determined based on RAB man-rem dose calculations in conjunction with ETSB cost-benefit studies. 11.3-6 1Rev. 2 - July 1981 2. The ETSB review of the gaseous waste management systems design capacity will encompass two major areas: a. The capability of the system to process gaseous wastes in the event of a single major equipment item failure. For nonredundant equipment or components, ETSB will assume a 3-week downtime every other year (10 days per year average). b. The capability of the system to process gaseous wastes at design basis fission product levels, i.e., from 1% of the fuel
