本文对低温核供热的意义、发展和现状作了简单的概述,对目前存在着的供热用反应堆的四种类型(压水型、升管沸腾型、有机物载热型及游泳池型)的主要特点作了概括的介绍,并对低温核供热堆在我们未来能源系统中的地位进行了讨论。本文还简单地介绍了清华大学游泳池式反应堆供热试验的情况。 This article gives a brief overview of the significance, development and current status of low-temperature nuclear heating. There are currently four types of reactors for heating (pressurized water, riser boiling, organic heat-transfer and swimming pool) The main features are briefly introduced, and the status of cryogenic nuclear reactor in our future energy system is discussed. This article also briefly introduced Tsinghua University swimming pool reactor heating test situation.
