压水堆电站蒸汽发生器管材应力腐蚀试验工作正按原定计划进行。在高温高压的高浓碱和含氯离子的介质中,我们已取得了预试验的成功。解决了国内以往在这方面试验的技术和设备的难题。为今后堆用蒸汽发生器材料的研究提供了条件。至今,已设计、建成四台直径为180mm高压釜试验装置,在这些装置中可进行蒸汽发生器管弯头等 Pressurized water reactor steam generator pipe stress corrosion test work is being carried out according to the original plan. We have achieved the success of the pre-test in high temperature and high pressure concentrated alkali and chloride containing media. Solve the problems of the technology and equipment that the country previously experimented in this area. It provides the conditions for the future research of steam generator materials. To date, four 180-mm-diameter autoclave test units have been designed and built in which steam generator pipe bends, etc., can be constructed
