Review of CHF experiment and prediction methods under motion condition

Because of exceptional economic benefits, stability, and high energy production efficiency, marine nuclear reactors are a major technology reserve for marine power supply. The Marine Nuclear Reactor's operating safety will be put to the test by the motion conditions it encounters. It is essential to investigate the critical heat flux characteristic under motion conditions since it is a crucial thermal hydraulic feature of nuclear reactor cores and one of the key criteria for thermal hydraulic design. Some CHF mechanisms under motion conditions have been obtained, and the CHF features of marine nuclear reactor cores under motion conditions have become a number of study issues, including model development and CHF experiments. Still, a few significant problems need to be addressed. In light of this, the experimental investigation and the development of the CHF prediction methods under motion conditions are summarized and analyzed in this work. This paper reviews the present correlations of CHF and the prediction methods created based on mechanism models. It also summarizes the experimental progress of the impacts of inclined motion, rolling motion, heaving motion, and coupling motion on CHF. Ultimately, this research field's development prospects are outlined and projected.
