APPARATUS WITH VACUUM CHAMBER AND OXYGEN FLOW SYSTEM FOR OXIDATION PROCESS OF URANIUM METAL CHIPS

摘要

A system for oxidation of uranium metal chips is provided to secure safety in oxidizing the uranium metal chips by converting the uranium metal chips into safe uranium oxide through vacuum heating and oxygen injection. A vacuum chamber(10) receives uranium metal chips(15) under a high temperature and vacuum condition. An oxygen supplier(30) is connected to the vacuum chamber through a connection pipe(31) having a solenoid valve and has a flow controller(33) to supply oxygen inside the vacuum chamber uniformly. A temperature recorder(50) is electrically connected to the vacuum chamber to measure and record temperature inside the vacuum chamber and temperature of the uranium metal chips. A cooling water tank(71) is connected to the vacuum chamber to supply cooling water to an outer wall of the vacuum chamber. A vacuum pump(75) is connected to the vacuum chamber through a connection pipe(76) to release the vacuum condition inside the vacuum chamber. A control panel(70) is installed at a front side of a frame to control temperature, oxygen flow, and degree of vacuum.
