Content:
channel checks, source checks, channel calibrations, and channel functional checks; compliance with action statements and remediation whenever the number of operational channels and applicability are less than the required minimum; sampling and analysis programs for continuous and batch mode releases, including provisions for the collection of grab and composite samples; and derivations of the lower limit of detections by categories of effluents or radionuclides and types of radiological analyses. The programs identified in the administrative controls section of the TS and elements of the SREC are reviewed using the provisions of Generic Letter 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 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 or NUREG-1302 and NUREG-0133. The ODCM should describe the methods used to calculate doses in accordance with the guidance of Regulatory Guides 1.109 and 1.111 or 1.113 using appropriate computer codes (e.g., LADTAP II (NUREG/CR-4013) and GASPAR II (NUREG/CR-4653)). 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 bases of dilution factors for liquid effluents (in-plant and beyond the point of release) and atmospheric dispersion (X/Q) and deposition (D/Q) factors for gaseous and particulate effluents, (3) provide specifications for maximum radioactivity levels in tanks containing liquids and descriptions of protective measures applied to spills
