rations at the point of entry in unrestricted areas. The hydrologic engineering staff will confirm whether the information and results comply with the acceptance criteria of SRP Section 2.4.13 and the requirements in 10 CFR 100.20(c). The health physics staff will use the resulting radionuclide concentrations in its evaluation once the approach used in modeling the transport of radioactivity in surface water or groundwater and resulting radionuclide concentrations in unrestricted areas are deemed acceptable by the hydrologic engineering staff. The corresponding guidance for the hydrologic engineering staff is described in SRP Section 2.4.13. Review Procedure As part of the review process, the staff will evaluate whether the applicant has applied a screening approach to the consequence analysis, starting with a simple worst-case scenario and then progressing to more realistic site-specific analyses. If the results of the worst-case BTP 11-6-5 Revision 4 – January 2016 analysis are not consistent to the SRP acceptance criteria, the applicant could conduct a more refined analysis using a site-specific conceptual model and parameters to demonstrate conformance with SRP acceptance criteria is demonstrated. If the results of site-specific analyses still do not conform to the SRP acceptance criteria, the applicant should propose TS limiting the total amount of radioactivity in such tanks and components, or explain its alternative method for meeting the regulations in sufficient detail for the staff to do an independent evaluation. In all instances, the applicant is requested to provide sufficient information for the staff to conduct independent analyses to confirm compliance with the regulations and conformance with SRP acceptance criteria. 1. Failure Mechanism and Radioactivity Releases The health physics staff will verify the identification of the liquid waste tank and components outside of containment or outdoors that could release the most radioactivity to the
