U-fission chamber

In order to prove the model calculation method and parameter, the 238U absolute fission rate in the case of 14 MeV neutrons penetrating through the special compo-site material was measured by minitype slab uranium fission chambers.

为检验计算方法与参数 ,用小型平板铀裂变室测量了铁球壳表面沿赤道方向不同位置 1 4MeV中子穿透实验模型后引起的2 38U绝对裂变反应率 ,并与MCNP/4A和ENDF/B V库数据计算结果相比较。
