Content:
health physics staff will use the resulting radionuclide concentrations in its analysis 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 above-described process for developing the assumed radioactive source term updates the methods and use of the computer code described in Chapter 4.4 and Appendices A and B of NUREG-0133, “Preparation of Radiological Effluent Technical Specifications for Nuclear Power Plants.” Applicants may propose and use alternate methods for developing radioactive source terms. In such instances, applicants are responsible for providing sufficient information and justification to enable the staff to perform an independent evaluation of any proposed alternative methods. With respect to the guidance of NUREG-0133, this BTP updates that guidance for applications submitted six months after the issuance of the final version of this BTP. However, the guidance of NUREG-0133 remains in effect for holders of nuclear power reactor OLs under 10 CFR Part 50 or COLs under 10 CFR Part 52 prior to the effective date of this BTP, and for applicants for nuclear power reactor OLs under 10 CFR Part 50 or COLs under 10 CFR Part 52 that have committed, in applications docketed with the NRC as of the effective date of this BTP, to specific guidance in assessing the radiological consequences of a postulated failure of a tank containing radioactive materials. 4. Calculations of Transport Capabilities in Groundwater or Surface Water The Hydrologic Engineering staff will make independent calculations of transport mechanisms and potential contamination pathways to surface water and groundwater environments that may, under accident conditions, transport radioactive contaminants to existing and future water users located in unrestricted areas.
