Hydraulic transients for loss of coolant accidents [PDF]
, 1986 This paper discusses calculations related to hydraulics in a loss of coolant reactor accident. Earlier calculations ignored the effect of emergency coolant injection. Present results show that if the ECS flow is considered, reactor coolant flow is maintained for much longer periods.

Temperature of JPDR Fuel at Loss-of-Coolant Accident
Journal of the Atomic Energy Society of Japan / Atomic Energy Society of Japan, 1964 Calculations are made of JPDR fuel temperature at loss-of-coolant accident. At the accident, the reactor is scrammed either by a low-reactor-water-level signal or by a high-enclosure-pressure signal, and the core spray system is initiated.In analyses, a fuel rod and a clad is devided into six and two annulus sections, respectively.

Effect of multiple-failure events on accident management strategy for CANDU-6 reactors
Nuclear Engineering and Technology, 2021 Lessons learned from the Fukushima Daiichi nuclear power plant accident directed that multiple failures should be considered more seriously rather than single failure in the licensing bases and safety cases because attempts to take accident management ...

Loss of coolant accident analysis under restriction of reverse flow
Nuclear Engineering and Technology, 2019 This paper analyzes a new method for reducing boiling water reactor fuel temperature during a Loss of Coolant Accident (LOCA). The method uses a device called Reverse Flow Restriction Device (RFRD) at the inlet of fuel bundles in the core to prevent ...
