    • PROBLEM TO BE SOLVED: To enable the multiple uses of fuel spent in a light water reactors only by conducting recovery treatment involving a simple heat treatment and the reusable fuel processing. SOLUTION: Fuel 1 spent in the light water reactor is extracted from cladding tubes for the light water reactor by recovery treatment involving a simple heat treatment (SP1) and is made reusable fuel by reusable fuel manufacturing (reusable fuel processing; SP2) and the reusable fuel is filled and loaded into cladding tubes for a fast reactor. Additionally, the reusable fuel in the cladding tubes in the fast reactor loaded into them is characterized in that it is made reusable fuel again by being extracted from the cladding tubes for the fast reactor through the recovery treatment involving the simple heat treatment (SP1) and by the reusable fuel manufacturing (SP2) at intervals of a recycle time set within the allowable durability period for the cladding tubes for the fast reactor in it and that the reloading into the fast reactor--the loading into it by filling the reusable fuel into new cladding tubes for the fast reactor--is repeated once or more.

    • 要解决的问题:为了能够通过进行简单的热处理和可重复使用的燃料处理的回收处理,能够在轻水反应堆中多次使用燃料。 解决方案:通过涉及简单热处理(SP1)的回收处理,在轻水反应堆的包覆管中提取燃料1,并通过可重复使用的燃料制造(可重复使用的燃料处理; SP2)制成可重复使用的燃料, 并且将可重复使用的燃料填充并装载到用于快速反应器的包层管中。 此外,装载在其中的快速反应堆中的包层管中的可重复使用的燃料的特征在于,通过通过简单热处理(SP1)的回收处理从用于快堆的包层管中提取可再生燃料, 通过可重复使用的燃料制造(SP2),间隔时间设定在其中用于其中的快速反应堆的包壳管的允许耐久期内,并且重新加载到快速反应堆中 - 通过将可重复使用的燃料装入 用于快速反应堆的新型包覆管 - 重复一次或多次。 版权所有(C)2006,JPO&NCIPI
