n sections, were revised by expanding technical guidance and identifying additional areas that warrant staff reviews and evaluations in assessing the consequences of a postulated failure of a radwaste tank and component containing radioactive materials. The additional areas of review address: 1. The revision incorporates the revisions presented in DC/COL-ISG-013, “Assessing the Radiological Consequences of Accidental Releases of Radioactive Materials from Liquid Waste Tanks for Combined License Applications,” on SRP Section 11.2 and BTP 11-6, in assessing the radiological consequences of accidental releases of radioactive materials from liquid waste tanks for COL applications.” (78 FR 6149, January 29, 2013 (ADAMS Accession No. ML12191A325)). 2. Compliance with 10 CFR Part 50, Appendix A, GDC 2 and GDC 61, as they relate to the consequence analyses conducted under SRP Section 11.2 using BTP 11-6. 3. The expanded discussions address design features to prevent, control, and collect radioactive materials in liquids from tank overflows and potential leaks for tanks located indoors and outside of containment that could result in uncontrolled and unmonitored releases, and design features applied to mitigate the effects of a postulated tank failure. 4. The staff’s review now consists of eight major steps and is shared by two technical disciplines. The review steps include the following evaluation: a. Failure mechanism and radioactivity releases, b. Mitigating design features, c. Radioactive source term, d. Calculations of transport capabilities in groundwater and surface water, e. Exposure scenarios and acceptance criteria, f. SRP dose acceptance criteria, g. Specifications on tank waste radioactivity concentration levels, and h. Evaluation findings for reviews of 10 CFR Part 52, COL and other applications. 5. The health physics staff is responsible for leading the evaluation of all steps except the fourth step. The fourth step, addressing the transport of
