equipment qualifications and model releases under design basis accident conditions for evaluation against reactor siting criteria and control room radiological habitability requirements. 4. assess the radiological impacts during postulated accidents, as required in SRP Section 2.4.13, SRP 11.2 using BTP 11-6, SRP 11.3 using BTP 11-5, and the analysis of RG 1.143 in assigning safety classifications to RWMS for design purposes and compliance with GDC 61. 5. consider design features or processes that would affect the development of the radioactive source terms in recognition of calculation methods and assumptions 11.1-20 Draft Revision 4 –August 2014 presented in NUREG-0016, NUREG-0017, and ANSI/ANS 18.1-1999, given differences between PWR and BWR plants. 6. provide a bounding assessment for ESP applications in demonstrating the capability to comply with the regulatory requirements of 10 CFR Part 20 and 10 CFR Part 50, Appendix I design objectives. II. ACCEPTANCE CRITERIA The acceptance criteria section was revised by providing clarification on methods used to derive radioactive source terms. The major revisions include: 1. Inclusion of revised staff guidance presented in: DC/COL-ISG-5, Interim Staff Guidance on NUREG-0800, SRP Section 11.1, “GALE86 Code for Calculation of Routine Radioactive Releases in Gaseous and Liquid Effluents to Support Design Certification and Combined License Applications.” The clarification notes that the calculation methods presented in NUREG-0016 and NUREG-0017 have been updated in a newer version of the associated computer code, denoted as GALE86. 2. The underlying assumptions used in developing design basis reactor coolant and reactor steam source terms was expanded to consider TS limits for halogens (I-131 dose equivalent) and noble gases (Xe-133 dose equivalent), as applied in analyses conducted using the guidance in SRP Sections 11.2 and 11.3 and SRP Chapter 15. 3. The revision notes that this SRP section does not include a
