CFR Title: 

Content:
endent from the existing reactor trip system (from sensor output to interruption of power to the control rods). (3) Each boiling water reactor must have an alternate rod injection (ARI) system that is diverse (from the reactor trip system) from sensor output to the final actuation device. The ARI system must have redundant scram air header exhaust valves. The ARI must be designed to perform its function in a reliable manner and be independent (from the existing reactor trip system) from sensor output to the final actuation device. (4) Each boiling water reactor must have a standby liquid control system (SLCS). The SLCS and its injection location must be designed to perform its function in a reliable manner. The SLCS initiation must be automatic and must be designed to perform its function in a reliable manner for plants granted a construction permit after July 26, 1984, and for plants granted a construction permit prior to July 26, 1984, that have already been designed and built to include this feature. (5) Each boiling water reactor must have equipment to trip the reactor coolant recirculating pumps automatically under conditions indicative of an ATWS.” Applicability - Systems and equipment used for mitigating ATWS events pursuant to the requirements of 10 CFR 50.62 and supporting data communication systems. Review Methods - SRP Section 7.8 provides guidance for the evaluation of conformance to the requirements of 10 CFR 50.62. (p) 10 CFR 52.47(b)(1): ITAAC for Standard Design Certification “The application (for design certification) must also contain: ...The proposed tests, inspections, analyses, and acceptance criteria that are necessary and sufficient to provide reasonable assurance that, if the inspections, test, and analyses are performed and the acceptance criteria met, a plant that references the design certification is built and will operate in accordance with the design certification...” Applicability - All I&C systems.
