Abstract EN
With the wide application of sea-based reactors, the impact of ocean conditions on the safety performance of reactors has gradually attracted attention.
In this paper, by establishing the thermal hydraulic transient analysis model and the critical heat flux (CHF) model of natural circulation system, the CHF characteristics in the rectangular channel of natural self-feedback conditions under ocean conditions are studied.
The results show that the additional acceleration field generated by ocean conditions will affect the thermal hydraulic parameters of the natural circulation system, that is, the external macroscopic thermal hydraulic field.
On the other hand, the boiling crisis mechanism will be affected, that is, the force on the bubble and the thickness of the liquid film.
Within the parameters of the study, ocean conditions have a great impact on CHF of natural circulation, and the maximum degradation of CHF is about 45%.
The obtained analysis results are significant to the improvement of design and safety operation of the reactor system.
