dependent 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, and thyroid will be determined using dose and source term calculations performed by the staff using methods described in NUREG-0016 or NUREG-0017, RG 1.112 and 1.111, and NUREG/CR-4653 (GASPAR II code). In calculating offsite gaseous effluent concentrations and doses to members of the public, the acceptability of the proposed short and long-term atmospheric dispersion and deposition parameters is determined as part of the review of the information discussed in SRP Section 2.3.5. The staff will determine conformance with Subsection II, Acceptance Criterion 1.E of this SRP section, concerning cost-benefit analysis using population cumulative dose calculations (person-Sv (person-rem)) and cost benefit analyses. In its review, the staff has considered the potential effectiveness of augmenting the proposed GWMS using items of reasonably demonstrated technology and should confirm that further effluent treatment will not effect reductions in cumulative population doses reasonably expected within an 80 km (50 mile) radius of the reactor, nor is it necessary to augment the design of the system for compliance with the cost-benefit ratio of Section II.D of Appendix I. RG 1.110 describes methods for performing such cost-benefit analyses. With respect to the types and locations of exhaust ventilation discharge points (e.g., plant stacks and
