rates the implementation of acceptance criteria. These cross-cutting review areas should be addressed by the reviewer for each technical subsection and relevant conclusions should be documented in the corresponding sections of the SER. 3. The review of the GWMS will evaluate P&IDs and system process flow diagrams to identify all sources and amounts of gaseous waste; points of collection of gaseous wastes; flow paths of gases through systems, including all potential bypasses to nonradioactive systems; treatment methods and expected decontamination factors or removal efficiencies and holdup or decay times; and points of release of gaseous effluents to the environment. With respect to potential bypasses, the review considers improper connection to nonradioactive systems and the possibility of uncontrolled and unmonitored gaseous releases and liquid releases from collection of GWMS water vapor condensates. This information is used to calculate the quantity of radioactive materials released annually in gaseous effluents during normal operations, including AOOs, using parameters and calculation techniques discussed in NUREG-0016 or NUREG-0017 and RG 1.112, as modified to reflect design-specific features. In such instances, the evaluation should confirm that the applicant has submitted sufficient information for the staff to conduct an independent evaluation of proposed modifications or alternative methods for estimating yearly releases of radioactive materials in gaseous effluents and for demonstrating compliance with NRC regulations using the SRP acceptance criteria and supporting regulatory guides. The results of this calculation will determine whether the proposed GWMS design meets SRP acceptance criteria 1 through 6 in Subsection II of this SRP section and relevant elements of SRP Section 11.1, on the basis of the source terms. Conformance with Subsection II, Acceptance Criteria 1.A, 1.B, 1.C, and 1.D of this SRP section concerning exposures of the total body, skin,
