深水池低温供热堆的研究进展

新的深水池低温供热堆堆芯在一个大而深的水池之中，利用水的静压力提高堆芯出口温度，从而满足区域供热系统的需要，这种供热堆结构简单，技术现实可行，当设计功率达到１２０ＭＷ或２００ＭＷ的规模时，投资和供热成本都比较低，采用深水池３型（ＤＰＲ－３）的天津核供热项目，已完成概念设计，初步选址及初步环境影响评价，并通过了中国有关部门的批准。目前，该项目正在准备展开工程实施工作。关键词：

Progress of study on deep pool reactors for district heating

The reactor core of the deep pool reactors(DDRs)is put in a large and deep pool, utilizing static water pressure to allow an outlet temperature of the core high enough to meet the requirements of the heating system.Simple structure and feasible technology of the DPR ensure lower capital investment and lower cost of heat for power levels of 120 MW(thermal)or 200 MW(thermal)commercial scale. The pre feasibility analysis for Tianjin nuclear project,including conceptual design of the DPR-3 plant,the preliminary siting and the preliminary environmental assessment,has had the evaluation and the approval of the expert group from Chinese nuclear authorities.At present,the Tianjin project is in preparation for engineering implementation.
