A Novel Idea of Power System Designing for Nuclear Plant with Small Modular Reactor

Abstract— When the massive earthquake and ensuing tsunami damaged the Daiichi nuclear power plant at Fukushima in Japan, the safety issues of nuclear power plant became the focus of the world again. This accident also urged the nuclear power plant designer to reexamine their designs before. The power system especially the emergency power system is responsible for providing power sources to all the electrical loads of the plant. The failure of emergency power supply could endanger the reactor, which was proved by the Fukushima crisis. Since the crisis was principally a result of flooding brought by the tsunami, in the future designing methods against flooding should be considered. The paper introduces a new concept of power system designing. Via systematic equipment layout, multiple power sources deployment, flexible water-resist cable route planning and predesigned mobile power source connecting interface, the stability and safety of the power system could reach another level.

Index Terms— Nuclear power, power system, small modular reactor.
