ECCS by providing redundant safety-grade systems that meet the recommendations of Regulatory Guide 1.1. 7. The applicant has met the requirements of GDC 36 with respect to the design of ECCS to permit appropriate periodic inspection of important components of the system. 8. The applicant has met the requirements of GDC 37 with respect to designing the ECCS to permit testing of the operability of the system throughout the life of the plant, including the full operational sequence that brings the system into operation. 9. The applicant has provided an analysis of the proposed ECCS relative to the acceptance criteria of 10 CFR 50.46, and with regard to the evaluation models the 6.3-18 Revision 3 - March 2007 guidance of Regulatory Guide 1.157 or alternatively Appendix K of 10 CFR 50. The applicant has demonstrated that their ECCS designs satisfy the criteria for peak cladding temperature, maximum calculated cladding oxidation, maximum hydrogen generation, coolable core geometry, and long-term cooling in accordance with an acceptable evaluation model. 10. The applicant has met II.K.3.18 of NUREG-0737, equivalent to 10 CFR 50.34(f)(1)(vii) for applicants subject to 10 CFR 50.34(f), with respect to eliminating the need for manual actuation of the BWR ADS to assure adequate core cooling. 11. The applicant has met II.K.3.21 of NUREG-0737, equivalent to 10 CFR 50.34(f)(1)(viii) for applicants subject to 10 CFR 50.34(f), with respect to reviewing the design of BWR core spray and low pressure coolant injection systems to ensure that the systems will automatically restart on loss of water level, after having been manually stopped, if an initiation signal is still present. 12. The applicant has met II.K.3.28 of NUREG-0737, equivalent to 10 CFR 50.34(f)(1)(x) for applicants subject to 10 CFR 50.34(f), with respect to the BWR ADS-associated equipment and instrumentation being capable of performing their intended functions during and following an accident, while taking no credit
