ter system, component cooling system, ultimate heat sink, and condensate storage facility) and assesses the capability of these systems to perform all functions required by the ECCS. The ASB SPLB will supply, on request, evaluations of portions of the power 16 conversion systems (e.g., steam supply lines, steam generators, feedwater systems) which interface with the reactor coolant system in such a way as to influence the course of a loss-of-coolant accident (LOCA) for a particular plant. d. The SPLB, as part of its primary review responsibility for SRP Section 9.3.1, reviews the capability and design of the pneumatic supply system for those BWR applicants which use a pneumatic supply for the ADS function.17 2. Instrumentation and Control Systems Controls Branch (ICSB HICB ), as part of its 18 primary review responsibility for SRP Section 7.3, reviews the adequacy of ECCS-associated controls and instrumentation with regard to the features of automatic actuation, remote sensing and indication, and remote control. 3. The Containment Systems and Severe Accident Branch (SCSB) performs the following reviews: a. The SCSB, as part of its review under SRP Section 6.2.2, addresses containment sump ECCS suction screen inlet design and evaluation guidance central to ensuring that containment sumps provide a reliable, long-term recirculation cooling capability and that ECCS pump performance will not be adversely affected by post-LOCA conditions impacting the sumps.19 b. The Containment Systems Branch (CSB SCSB) verifies that portions of the 20 ECCS penetrating the containment barrier are designed with acceptable isolation features to maintain containment integrity for all operating conditions, including accidents, as part of its primary review responsibility for SRP Section 6.2.4. 4. The Power Systems Branch (PSB) Electrical Engineering Branch (EELB) as part of its 21 primary review responsibility for SRP Sections 8.1, 8.2, 8.3.1, and 8.3.2, reviews the adequacy of the power
