e 2, Columns 1 and 2) and Note 4 for mixtures of radionuclides. 3. GDC 61 requires that the facility design include shielding used for the safe storage and handling of radioactive materials, and other systems containing radioactivity, for the purpose of assessing radiological safety under normal operations and postulated accident conditions. Inventories of the amounts of radioactive materials contained in RWMS must be determined for the purpose of assessing whether the design of RWMS assures radiological safety under normal operations and postulated accident conditions. NUREG-0016, NUREG-0017, or ANSI/ANS 18.1-1999 describe acceptable methods in determining the inventories of radioactive materials in RWMS components during normal operations, which could be modified to develop source terms for postulated accidents. Meeting this requirement of GDC 61 provides reasonable assurance that the necessary information is available to identify the amounts of radioactive materials contained in RWMS and assess the radiological impacts during postulated accidents. Acceptable NRC guidance and methods are described in SRP Sections 2.4.13, “Accidental Releases of Radioactive Liquid Effluents in Ground and Surface Waters;” SRP 11.2 11.1-12 Draft Revision 4 –August 2014 using Branch Technical Position (BTP) 11-6, “Postulated Radioactive Releases Due to Liquid-containing Tank Failures;” SRP 11.3 using BTP 11-5, “Postulated Radioactive Releases Due to a Waste Gas System Leak or Failure,” (Former Section 11.3 BTP has been separated into individual sections), and the analysis of RG 1.143, “Design Guidance for Radioactive Waste Management Systems, Structures, and Components Installed in Light-Water-Cooled Nuclear Power Plants,” in assigning safety classifications to RWMS for design purposes. III. REVIEW PROCEDURES These review procedures are based on the identified SRP acceptance criteria. For deviations from these acceptance criteria, the staff should review the
