nce 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 The clarification notes that the calculation methods presented in NUREG-0016 and NUREG-0017 have been updated in a newer version of the associated computer code, denoted as GALE86. 2.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 review of the generation of neutron-activated components, in-core neutron detectors, or spent-fuel and their associated source terms since they do not originate from primary and secondary coolants and reactor steam. III. REVIEW PROCEDURES The review procedures section was updated in recognition of the revisions identified in the areas of review and acceptance criteria sections, as noted above. The revision addresses the staff review and evaluation of proposed augmentation of programmatic elements in assessing the adequacy of the design and resulting effects on the development of associated radioactive source terms. The revision provides guidance on the review of the proposed technical resolution of USIs and medium- and high-priority GSIs identified in the version of NUREG-0933 current on the date 6 months before application and that are technically relevant to the design; how operating experience insights have been incorporated into the plant design; and information necessary to demonstrate compliance with technically relevant portions of the TMI requirements. The revision provides clarification in confirming that the application provides a bounding assessment
