The general-purpose CFD code FLUENT is used to calculate the transient process of China helium-cooled solid breeder test blanket module (TBM) under loss of coolant accident (LOCA) scenario.
And then we have gas cooled reactors which can use supercritical carbon dioxide or helium.
然后我们有气体冷却反应堆，那能使用超临界二氧化碳或者氦。

When it had cooled further, these protons and neutrons were able to get together to form the nuclei of the lightest elements-hydrogen, helium and lithium.
