【日本《电气杂志》1981年4月报道】日本动力堆·核燃料开发事业团的快堆“文殊”的堆芯和再生区是使用贫化铀和钚的混合氧化物。当然,使用天然铀也是可以的。但由于用贫化铀时U-238浓度相对较高,增殖率可达1.25(天然铀的增殖率为1.22),再加上贫化铀的价格比天然铀便宜得多,因此就成了考虑采用贫化铀的根据。虽然增殖率仅高0.03,但也不能忽视。
[Japanese Electric Journal] reported in April 1981 that the core and regeneration zone of the fast reactor “Wusuk” of the Japan Power Reactor and Nuclear Fuel Development Corporation is a mixed oxide using depleted uranium and plutonium. Of course, it is also possible to use natural uranium. However, due to the relatively high concentration of U-238 when depleted uranium is used, the proliferation rate can reach 1.25 (the natural uranium has a reproducibility rate of 1.22), and the depleted uranium is much cheaper than natural uranium, so it is considered Use the basis of depleted uranium. Although the proliferation rate is only 0.03 higher, it cannot be ignored.
