nal capability. 9. The design provisions and proposed program (including technical specifica- tions at the operating license stage of review) for periodic inservice inspection, operability testing and leak rate testing of each system or component. 10. The functional aspects of instrumentation provided to monitor system or system component performance. 11. The extent of sharing of system components between sites or between units at a multi-unit site. At the construction permit (CP) stage of review the design of the systems pro- vided for monitoring and reducing the concentrations of combustible gases within the containment may not be completely determined. In such cases, CSB reviews the applicant's preliminary designs and statements of intent to comply with the acceptance criteria for such systems. At the operating license (OL) stage, CSB reviews the final designs of these systems to verify that they meet the accept- ance criteria detailed in subsection II of this SRP section. CSB will coordinate other branch evaluations that interface with the overall review of the combustible gas control matter, as follows: The Mechanical Engineering Branch (MEB) will review seismic design and quality group classi- fications as part of its primary review responsibility for SRP Section 3.2.1 and SRP Section 3.2.2, respectively. The Instrumentation and Control Systems Branch (ICSB), as part of its primary review responsibility for SRP Section 7.5, will evaluate the actuation and control features of active components. The Equipment Qualification Branch (EQB), as part of its primary review responsi- bility for'SRP Section 3.11, will evaluate the qualification test program for electric valve operators, fans, hydrogen/oxygen sampling or analyzing equipment, 6.2.5-2 Rev. 2 - July 1981 and sensing and actuation instrumentation of the plant protection system, located both inside and outside the reactor containment. The Chemical Engi- neering Branch (CMEB), as part of its primary review
