核电站堆型的分类方法有很多种,按照用途来分,可分为动力堆、生产堆、研究堆、特殊用途堆等;按照冷却剂和慢化剂来分,又可分为压水堆、沸水堆、重水堆、气冷堆、压力管式石墨沸水堆、快中子增殖堆等。全世界核电站中以压水堆、沸水堆所占的比例最大。各种堆型核电机组数占核电总机组数的份额:压水堆占 There are many types of nuclear power plant heap classification, according to the use of points, can be divided into power reactor, production reactor, research reactor, special purpose reactor; in accordance with the coolant and moderator to points, and can be divided into pressurized water reactor, Boiling water reactor, heavy water reactor, gas-cooled reactor, pressure tube graphite boiling water reactor, fast neutron multiplication reactor. The world’s largest nuclear power plant to PWR, boiling water reactor accounted for the largest proportion. The number of nuclear reactors of various heap types accounts for the share of the total number of nuclear power generating units: PWRs
