A. The purpose of BTP ETSB 11-5 is to provide guidelines on postulated radioactive releases due to a GRS leak or failure. The intent is to minimize potential radiation and to minimize the radiological consequences of a single failure of an active component in the waste gas system. Following the assumptions and guidelines of BTP ETSB 11-5 provide assurance that releases of radioactive materials would not result in doses that would exceed a small fraction (i.e., 10%) the guidelines of 10 CFR Part 100 for a postulated failure of the GRS or postulated leak from the GRS.58 III. REVIEW PROCEDURES The reviewer will select and emphasize material from this SRP section, as may be appropriate for a particular case. 11.3-11 DRAFT Rev. 3 - April 1996 1. In the ETSB SPLB 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 provided 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 calculational techniques given in NUREG 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 proposed gaseous waste management systems design meets the acceptance criterion of subsection II.B.1.d of this SRP section. Compliance with the acceptance 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 RAB PERB dose calculations using the ETSB SPLB calculated source term.
