lated failure of a tank containing radioactive materials. Similarly, this BTP updates the guidance of Section 4.4 and Appendices A and B of NUREG-0133 addressing the development of assumed radioactive source terms in failed tank and components. The reasons for updating the guidance of NUREG-0133 is that the computer code is no longer supported by the NRC, the computer code considers a very limited suite of radionuclides in the consequence analysis, and the acceptance criteria built into the code are not consistent with the current effluent concentration limits of Appendix B (Table 2, Column 2) to 10 CFR Part 20. While this BTP provides equivalent guidance, applicants may propose and use alternative methods in 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 method. The guidance in Appendices A and B 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 as of BTP 11-6-16 Draft Revision 4 – August 2014 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. D. EVALUATION FINDINGS The health physics and hydrologic engineering staff will document the results of the evaluation of site characteristics and conformance with the SRP radiological acceptance criteria. In its evaluation and conclusions, the health physics staff will refer to the evaluation performed by the hydrologic engineering staff and not reiterate in its analysis and conclusions the results presented by the hydrologic engineering staff in response to SRP Section
