pliance with it is not required. However, an applicant is required to identify differences between the design features, analytical techniques, and procedural measures proposed for its facility and the SRP acceptance criteria and evaluate how the proposed alternatives to the SRP acceptance criteria provide acceptable methods of compliance with the NRC regulations. Appropriate sections of the following Regulatory Guides are used by the staff for the identified acceptance criteria. Regulatory Guide 1.23, “Onsite Meteorological Programs,” presents criteria for an acceptable onsite meteorological monitoring program and the resulting meteorological database that may be used in this SRP section as input to the atmospheric dispersion estimates. Regulatory Guide 1.78, “Evaluating the Habitability of a Nuclear Power Plant Control Room During a Postulated Hazardous Chemical Release,” presents criteria for characterizing atmospheric dispersion conditions for evaluating the consequences of airborne hazardous material releases to the control room. Regulatory Guide 1.145, "Atmospheric Dispersion Models for Potential Accident Consequence Assessments at Nuclear Power Plants," presents criteria for characterizing atmospheric dispersion conditions for evaluating the consequences of radiological releases to the EAB and LPZ. Regulatory Guide 1.194, “Atmospheric Relative Concentrations for Control room Radiological Habitability Assessments at Nuclear Power Plants,” presents criteria for characterizing atmospheric dispersion conditions for evaluating the consequences of radiological releases to the control room. Older plants licenced under 10 CFR Part 50 may have also used the following regulatory guides instead of Regulatory Guide 1.145 for characterizing atmospheric dispersion conditions for evaluating the consequences of radiological releases to the EAB and LPZ: Regulatory Guide 1.3, “Assumptions Used for Evaluating the Potential Radiological Consequences of a Loss of
