toring of Secondary Side Water Chemistry in PWR Steam Generators).11 2. CMEBEMCB will coordinate evaluations of other branches that interface with the 12 overall review of the steam generator blowdown system as follows: a. The Mechanical Engineering Branch (MEB)(EMEB) reviews the system's 13 seismic design and quality group classification as part of its primary review responsibility for SRP Sections 3.2.1 and 3.2.2, respectively. b. Structural Engineering Branch (SEB)The Civil Engineering and Geosciences Branch (ECGB) determines the acceptability of the design analysis, procedures, 14 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 responsibility for SRP Sections 3.3.1, 3.3.2, 3.5.3, 3.7.1, 3.7.2, 3.7.3, 3.7.4, 3.8.4, and 3.8.5. c. tThe liquid, and gaseous, and solid waste treatment aspects of the SGBS are reviewed in SRP Sections 11.2, and 11.3, and 11.4, and the liquid and gaseous 15 process and effluent radiological monitoring is are reviewed in SRP Section 16 11.5 by Effluent Treatment Systems Branch (ETSB)Plant Systems Branch (SPLB) as part of its primary review responsibility for those sections. 17 d. Auxiliary Systems Branch (ASB)The SPLB, as part of its primary review 18 responsibility for SRP Section 3.6.1, evaluates the effect of high- and moderate-energy system piping failures to assure ensure that safety-related 19 equipment will not be made inoperable. e. The SPLB evaluates the capabilities of the high-energy portion of the SGBS to 20 withstand the effects of internally generated missiles both outside containment in SRP Section 3.5.1.1 and inside containment in SRP Section 3.5.1.2. f. the Containment Systems Branch (CSB)The Containment Systems and Severe Accident Branch (SCSB) determines that the blowdown lines
