介绍了２００ＭＷ常压采暖供热堆的方案设计及其与加压供热堆的比较．这种反应堆堆芯放在一个大而深的水池之中，利用水的静压力提高了堆芯出口的温度，其供热水温可以满足集中供热系统的要求，而反应堆却工作在常压之下．与加压供热堆相比具有结构简单、固有安全、投资低、供热成本低以及在我国容易实施的特点 The scheme design of 200 MW atmospheric heating and heating reactor and its comparison with pressurized heating reactor are introduced. The reactor core is placed in a large, deep pool using hydrostatic pressure to raise the temperature at the outlet of the core. The temperature of the hot water supply can meet the requirements of a central heating system, while the reactor operates at atmospheric pressure under. Compared with the pressurized heating reactor has the advantages of simple structure, inherent safety, low investment, low heating cost and easy implementation in our country
