摘　　要：49-2游泳池式轻水反应堆(以下简称49-2堆)是一座轻水冷却、轻水慢化的研究堆,其一回路冷却水直接与燃料元件接触,水质好坏直接影响池壁、一回路管道等金属构件的使用寿命,因此需要通过一些简便、快速的检测手段对水质进行监测,进而严格控制反应堆水中的杂质含量。本文对49-2堆一回路水质检测方法及测量结果进行总结分析,结果表明,49-2堆在过去几十年的运行中一回路水质检测方法在逐步更新与完善,49-2堆运行人员严格控制一回路水质,始终保持在运行限值之内,保障了反应堆的安全运行。这一结果可为49-2堆的应用和退役管理提供参考依据。49-2 swimming pool reactor is experiment research reactor by using light water coolinig and slowing down.The primary water is in direct contact with the fuel.Water quality affects pipeline life.,thus it’s necessary to bring forward a simple method to control the impurities in the water as well as preventing the same situation from happening again.In order to achieve this goal,this article summarizes and statistics the water quality detection methods and measurement results of the primary circuit of the 49-2 reactor.The results show that the ion detection methods of the primary circuit of the 49-2 reactor have been gradually updated and improved in the past few decades of operation.The operators of the 49-2 reactor strictly control the water quality of the primary circuit and always maintain it within the operating limits,ensuring the safe operation of the reactor.This result can provide a reference basis for the application and retirement management of the 49-2 reactor for continued operation.
