Abstract

Abstract

Steam generator （SG） is one of the key equipment in nuclear power plant, and its heat transfer tube is the weakest link in the primary pressure boundary. In order to solve the problem that SG small curvature heat transfer tube cannot realize one-time full tube eddy current detection due to the influence of bending tube curvature, which leads to the extension of overhaul period and the increase of radiation risk of personnel, a pneumatic probe with spring skeleton structure and air damping device is designed in this paper. The probe drive retraction device and the pneumatic drive device for internal and external air supply are adopted innovatively, and a new type of automatic eddy current inspection system for SG heat transfer tube is developed, which can realize one-time full-tube eddy current detection of SG small curvature heat transfer tube.
- Small curvature heat transfer tube,
