Content:
to circulate sufficient air to prevent accumulation of inflammable or explosive gas or fuel-vapor mixtures from components such as storage batteries and stored fuel. e. The capability of the system to automatically actuate compoments not operating during normal conditions, or to actuate standby components (redundant equipment) in the event of a failure or malfunction, as needed. f. The capability of the system to control airborne particulate material (dust) accumulation. 3. The ASB also performs the following reviews under the SRP sections indicated: a. Review of flood protection is performed under SRP Section 3.4.1. b. Review of the protection against internally generated missiles is performed under SRP Section 3.5.1.1. c. Review of the structures, systems, and components to be protected against externally generated missiles is performed under SRP Section 3.5.2. d. Review of high- and moderate-energy pipe breaks is performed under SRP Section 3.6.1. The ASB will coordinate evaluations performed by other branches that interface with the overall evaluation of the system as follows. The ICSB and PSB deter- mine the adequacy of the design, installation, inspection, and testing of all electrical components (sensing, control, and power) required for proper opera- tion as part of their primary review responsibility for SRP Sections 7.3 and 8.3.1, respectively. The SEB determines the acceptability of the design analyses, procedures, and criteria used to establish the ability of seismic Category I structures housing the system and supporting systems to withstand the effects of natural phenomena such as the safe shutdown earthquake (SSE), the probable maximum flood (PMF), and tornado missiles as part of its primary review respon- sibility for SRP Sections 3.3.1, 3.3.2, 3.5.3, 3.7.1 thru 3.7.4, 3.8.4, and 3.8.5. The MEB determines that.the components, piping, and structures are 9.4.5-2 Rev. 2 - July 1981 designed in accordance with.applicable codes and standards as part of
