【 摘 要 】

With steam generator running more and more years, sludge will accumulate on the surface of 9th tube support plate, causing broached holes clogging and heat transfer efficiency decreasing. In order to know the situation of sludge deposit and provide evidence of judging whether soft chemical cleaning is necessary, the 9th tube support plate automatic TV inspection equipment is required and needs to be developed based on the upper structure of CPR1000 steam generator. In this paper, the application surroundings and requirements were analyzed. The inspection method, general design, magnetic crawler, probe characteristics and mockup tests were described, especially how to insert the probe into bundles to achieve inspection scope was introduced.
