The heat pipe cooled micro molten salt reactor (micro-MSR) which is an innovative concept combining molten salt reactor and heat pipe technology, is proposed in this work and furthermore, a 50 kWth version of micro-MSR is designed.

This paper presents a preliminary approach to thermo-hydraulics of the molten salt, which plays the role of both heat generator and coolant in the Molten Salt Reactor (MSR). This kind of nuclear reactor represents one of the "Generation IV International Forum" concepts that can be used for actinides burning, production of electricity, production of

The micro-MSR is a small (50 kWth) fast molten salt reactor cooled by heat pipes, and has certain attractive features, such as liquid fuel without need of fuel assembly fabrication, inherent safety, strong environmental robustness and high reliability, which make it potentially be implemented in the applications in space, ocean and other off ...

Therefore, in the previous study, the thermal sizing and intermediate heat exchanger of the 6.5MW th molten salt reactor system was performed Inlet (°C)as shown in Figure 1 [5]. However, to carry out the conceptual design of the intermediate loop, it is necessary to select a pipe diameter suitable for the heat exchanger. Therefore, in this study,

Using heat pipe might help to improve the heat dissipation performance of passive residual heat removal system (PRHRS) of molten salt reactor (MSR). In this paper, a preliminary concept PRHRS of MSR using sodium heat pipes is proposed detailedly, and then the transient performance of high temperature sodium heat pipe is numerically simulated in ...
