ActiveEddy current testing of fuel element end cap weld for PHWR
重水堆核电厂燃料元件端塞焊缝涡流检测
Application Summary AI generated
This standard specifies the eddy current testing method for detecting surface and near-surface defects in the end cap welds of fuel elements used in pressurized heavy water reactors (PHWR). It is applied during manufacturing and quality control in nuclear fuel fabrication facilities to ensure weld integrity and prevent fuel rod failure under reactor operating conditions. The standard defines testing parameters, calibration procedures, and acceptance criteria specific to the geometry and material of PHWR fuel element end cap welds.
