At nuclear power plant (NPP), reactor core is a heat-producing device through controlled nuclear fission reaction and transfer them by reactor coolant pumps (RCP). Since decay, heat is sufficient to meltdown the reactor core. Therefore RCP serviceable continuously for overlong period after the chain reaction stopped. At this article focus on long-term uninterrupted power supply to the RCP because, lack of grid supply for long period might be concerning with nuclear safety-security issue that we see at Fukushima daiichi NPP accident. Generated electricity of NPP is transfer though grid towers. They are arrange periodically and go far away from NPP substation. After a distance from NPP if, intentionally single tower of all different grid lines breakdown though terrorist attacks then create a major destructive violence. At this situation, NPP’s unit generator tripped and longtime auxiliary power supply depend on battery backup, uninterruptible power supply (UPS) or Emergency Diesel Generator (EDG). Though re-construction of towers are lengthy process and sooth to say EDG, UPS, batteries are not sufficient for longtime continuous power supply without interruption. To overcome this situation, established such a complete small power generation unit along with NPP. Due to several advantages, a diesel engine power plant is best. All single engines are assemble at parallel and capable to maintain the supply continuity to make it almost 100 % reliable. Hence, additional diesel plant along with NPP obviously enhance the safety of RCP’s electrical power supply system and improving the NPP safety parameter.
