Estimation of LOCA Break Size Using Cascaded Fuzzy Neural Networks
Nuclear Engineering and Technology, 2017 Operators of nuclear power plants may not be equipped with sufficient information during a loss-of-coolant accident (LOCA), which can be fatal, or they may not have sufficient time to analyze the information they do have, even if this information is ...

ASSESSMENT OF HEAT TRANSFER IN FUEL CHANNEL OF INDIAN PHWR UNDER POSTULATED LARGE BREAK LOSS OF COOLANT ACCIDENT: EXPERIMENTAL AND NUMERICAL STUDY [PDF]
EPJ Web of Conferences, 2021 The behaviour of the channel under postulated large break LOCA scenario had been a prime safety concern. The radiative heat transfer is predominant in a channel when the convective cooling environment is marred. The estimation of temperature distribution

Numerical Simulation Study on the Air/Water Counter- current Flow Limitation in Nuclear Reactors
Brazilian Journal of Radiation Sciences, 2021 After a loss-of-coolant accident (LOCA) in a Pressurized Water Reactor (PWR), the temperature of the fuel elements cladding increases dramatically due to the heat produced by the fission products decay, which is not adequately removed by the vapor ...

Study on Nitrogen Migration and Release Models under Pressure Relief Condition during LOCA
Yuanzineng kexue jishu, 2023 Nitrogen pressurization is widely used in nuclear reactor (such as passive nitrogen-type accumulators and nitrogen regulator) because of passive mechanism. However, nitrogen pressurization brings new challenges.
