tegories of effluents or radionuclides and types of radiological analyses. The programs identified in the administrative controls section of the TS and elements of the RETS/SREC are reviewed using the provisions of GL 89-01 and NUREG-1301 or NUREG-1302. B. ODCM—The ODCM is reviewed to determine whether descriptions of the methodology and parameters used for calculating offsite doses to members of 11.5-33 Revision 6 – January 2016 the public, resulting from gaseous and liquid effluent releases, meet the regulatory requirements and guidance noted above. The procedural details and programmatic elements of the ODCM should be based on the guidance of NUREG-1301 (PWRs) or NUREG-1302 (BWRs) and NUREG-0133 and NUREG-0543 for either type of reactor. The ODCM should describe the methods used to calculate doses in accordance with the guidance of RGs 1.109, “Calculation of Annual Doses to Man from Routine Releases of Reactor Effluents for the Purpose of Evaluating Compliance with 10 CFR Part 50, Appendix I,” and RG 1.111, Methods for Estimating Atmospheric Transport and Dispersion of Gaseous Effluents in Routine Releases from Light-Water-Cooled Reactors,” or RG 1.113, “Estimating Aquatic Dispersion of Effluents from Accidental and Routine Reactor Releases for the Purpose of Implementing Appendix I,” using appropriate computer codes (e.g., LADTAP II (NUREG/CR-4013, “LADTAP II— Technical Reference and User Guide,” issued April 1986) for liquid effluents and GASPAR II (NUREG/CR-4653, “GASPAR II—Technical Reference and User Guide,” issued March 1987)) for gaseous effluents. The ODCM should (1) identify all liquid and gaseous effluent release points and the types and locations of installed radiological instrumentation used to monitor and control effluent releases, (2) describe parameters and provide justification of values used to derive effluent release rates and alarm setpoints, including the basis of dilution factors for liquid effluents (in-plant and
