Abstract

Abstract

Joule heated ceramic melter is the core equipment in the high level liquid waste vitrification process, and the vitrified waste in the melter is poured into the canister by means of bottom discharge. In order to repair the melter discharge pipe, the damaged discharge pipe was inspected, a special device was developed to cut, grind and clean the upper section of the discharge pipe, and a docking device was designed for easy installation, fixing and disassembly. Various sealing structures designed were tested by experimental methods, and the optimal sealing scheme was selected. Through the test, the reliability of the overall structure and thermal compensation function of the docking device was verified. The installation and use of the docking device show that it is simple in structure, convenient to install and reliable in sealing. The function of the discharge pipe is successfully restored, and the replacement of high-level vitrified waste in the melter is successfully completed, which creates favorable conditions for ensuring the good state of the melter and welding repair of the discharge pipe, and accumulates experience for similar work in radioactive high-temperature environment.
