Abstract: Manipulator is a key part of mobile spent high active radioactive source (SHARS) conditioning equipment. Its stabilitywill affect the successful operation of the conditioning equipment. Based on the failure analysis of ZC205B master slave hinged manipulator in cold test, thispaper is intended to provide the identification and correction of the problems existing in the process of its operation, for the purpose of providing guidance on the future thermal test.

Key words: Manipulator, Conditioning equipment, Failure analysis
