5MW 核供热堆的水化学实验研究

EXPERIMENTAL RESEARCH OF WATER CHEMISTRY FOR 5 MW NUCLEAR HEATING REACTOR

实验研究了５ＭＷ核供热实验反应堆的水化学特性。该堆是一体化自稳压自然循环壳式轻水反应堆，测量了一回路冷却水水质的化学成分，如溶解氧、ｐＨ值、电导率、硝酸根、氯离子、氟离子及腐蚀产物、溶解氢等。讨论了反应堆结构对水化学的影响。

The experimental research of primary coolant on 5 MW nuclear heating reactor (NHR) is reported.The 5 MW NHR is an integrated self pressuring, natural circulation, vessel type, light water reactor. The reactor structure influence on water chemistry is described.The chemistry components for coolant water of primary loop of reactor, such as dissolved oxygen, pH, conductivity, nitrate, chloride, fluoride, corrosion products are established. The main performance of water chemistry for NHR is investigated and discussed.
