ts of discharge or release into the environment, and at all appropriate offsite dose receptor locations and potential exposure pathways. The estimates of the effluent source terms (Ci/yr) and effluent concentrations (µCi/ml) are evaluated to determine whether they are consistent with the range of possible requested thermal power levels. For gaseous effluents, the staff confirms that atmospheric dispersion characteristics and deposition parameters used in calculating offsite doses are consistent with the information presented in Section 2.3.5 of the applicant’s technical submittal. The staff should confirm the approach used by the applicant in developing the annual average gaseous effluent source terms from all release points (e.g., plant stack, building vents, etc.). For a source term based on a single type of reactor design, the staff will confirm that the applied source term is consistent with that presented in the current revision of the DC for the selected reactor technology. For a source term based on two or more types of reactor designs, the staff will confirm that the source term, as a plant parameter envelope, is consistent with that presented in the current revision of each design certification, or other reactor technology, and conservatively bounding over all expected radionuclides. In the absence of certain circumstances, such as a compliance or adequate protection issue, 10 CFR 52.39 precludes the staff from imposing new site characteristics, design parameters, or terms and conditions on issues that were resolved as part of the ESP at the COL stage. The applicant should provide enough information for the staff to conclude that the ESP application provides a bounding assessment in demonstrating the 11.3-30 Draft Revision 4 – August 2014 capability to comply with the regulatory requirements of 10 CFR Part 20 and 10 CFR Part 50, Appendix I design objectives. Accordingly, the reviewer should ensure that physical attributes (relevant to the review
