<p>PURPOSE:To obtain a simple disassembling method for a spent fuel rod which does not require cutting with a cutting blade being apt to cause malfunction of using device. CONSTITUTION:A spent fuel rod O1a is pinched with electrode plates 2 and the spent fuel rod O1a is heated with a current supplied from a power supplier 3 by way of a circuit cables 7. By supplying power in accordance with the electric resistance of the spent fuel rod O1a, it is heated over 1200 deg.C and below 1500 deg.C, held for more than 5 minutes and cooled. By this processing, the zirconium type material of the fuel clad is oxidized to be ceramic type zirconium oxide and is destructed.</p> |
