Abstract EN
This paper presents capacity of the passive decay heat removal system (DHRS) operated under the natural circulation conditions to remove decay heat inside the main vessel of the Lead-bismuth eutectic cooled Fast Reactor (LFR).
The motivation of this research is to improve the inherent safety of the LFR based on the China Accelerator Driven System (ADS) engineering project.
Usually the plant is damaged due to the failure of the main pumps and the main heat exchangers under the Station Blackout (SBO).
To prevent this accident, we proposed the DHRS based on the diathermic oil cooling for the LFR.
The behavior of the DHRS and the plant was simulated using the CFD code STAR CCM+ using LFR with DHRS.
The purpose of this analysis is to evaluate the heat exchange capacity of the DHRS and is to provide the reference for structural improvement and experimental design.
The results show that the stable natural circulations are established in both the main vessel and the DHRS.
During the decay process, the heat exchange power is above the core decay heat power.
In addition, in-core decay heat and heat storage inside the main vessel are efficiently removed.
All the thermal-hydraulics parameters are within a safe range.
Moreover, the highest temperature occurs at the upper surface of the core.
A swirl occurs at the corner of the lateral core surface and some improvements should be considered.
And the natural circulation driving force can be further increased by reducing the loop resistance or increasing the natural circulation height based on the present design scenario to enhance the heat exchange effect.
