| Abstract: | Redundant power supply can improve the safety and reliability of nuclear power plant auxiliary power system. Based on the theory of reliability, three kinds of model are designed and deduced. Those are one-way and two-way switching double redundancy, one-way switching multilevel redundancy. The system structures are analyzed. One-way switching multilevel redundancy is selected as the actual auxiliary power supply. This model conforms to some design concept. Such as the principle of defense in depth, single failure criteria. The power supply priority level and maintenance of engineering requirements are considered. |
