In the medical isotope reactor to separate and purify the medical isotope 99Mo and 131I, the reactive heat is constantly generated in the process of reaction, associated with the production of fission gas. In order to control the average temperature (usually≤80℃) of the reactor to prevent the sample from volatilizing, the cooling system of the reactor need to be designed carefully.

在使用医用同位素反应堆分离提纯医用同位素99Mo和131I时，由于反应过程中会不断产生热量并伴随裂变气产生，为了控制堆内平均温度(通常≤80℃)以使样品不致挥发，这就需要精心设计反应堆的冷却系统。
