Low-pressure core spray system

These i high-pressure core spray (HPCS) system that replaced the HPCI system. The const e motor-driven pump train powered by its own electrical division complete with J diesel fhese plants also have a single train low-pressure core spray system, as well as a RHR system similar to the system design in the BWR. 3/4 group.

Several other systems are available to control room operators to keep the reactor cool during an emergency. These include the High Pressure Core Spray System, Low Pressure Core Spray System, Residual Heat Removal System, Low Pressure Coolant Injection, and Suppression Pool Cooling. All of these systems require both AC and DC power, plus a sufficient flow of coolant water connected to the ultimate heat sink. At Fukushima this ultimate heat sink was the Pacific Ocean (US Nuclear Regulatory Commission, n.d.a). [Pg.87]
