ESF fluids.18 DRAFT Rev. 2 - April 1996 6.1.1-4 Review Interfaces EMCB also performs the following related reviews under the SRP Sections indicated:19 1. Reviews the adequacy of programs for assuring the integrity of bolting and threaded fasteners as part of its primary review responsibility for SRP Section 3.13 (proposed).20 2. Reviews the compatibility of ESF fluids with organic materials (coatings) and the use of coatings in containment, including their qualifications, as part of its primary review responsibility for SRP Section 6.1.2.21 3. Reviews the stability of core and containment spray solutions under long term storage and prolonged spray operating conditions, including solutions containing boron for reactivity control and other additives for reacting with gaseous fission products, as part of its primary review responsibility for SRP Section 6.5.2.22 4. Determines the acceptability of the reactor coolant chemistry and associated chemistry controls (including additives such as inhibitors) as it relates to corrosion control and compatibility with ESF materials, as part of its primary review responsibility for SRP Sections 5.4.8 "Reactor Water Cleanup System (BWR)" and 9.3.4 "Chemical and Volume Control System (PWR)."23 In addition, the EMCB will coordinate other branches' evaluations that interface with the overall review of the ESF materials as follows:24 1. The Mechanical Engineering Branch (EMEB) determines the adequacy of the design for structural integrity of components and their supports including the adequacy of design fatigue curves for ESF materials with respect to cumulative reactor service-related environmental and usage factor effects, as part of its primary review responsibility for SRP Section 3.9.3.25 2. The SCSB determines the adequacy of post-loss of coolant accident (LOCA) hydrogen control, including control of the volume of hydrogen gas expected to be generated by metal-water reaction involving the fuel cladding and radiolytic
