设计的U_3Si—A1,UO_2一Al和U一2(wt)％zr三种燃料元件的铀密分别为9.763,4.366和17.93g/cm~3;U~235的加浓度分别为1.55％、2.0％和O.9％,最大燃耗分别为12658.7、12658.7和5000MWD/T。三种元件均可在水温134℃,热负荷0.7095×10 e大卡/米~2·时的条件下工作。U_3Si—Al和UO_2—A1元件辐照尺寸稳定性良好,U—2(wt)％Zr元件在达到最大燃耗后直径为Φ36.2lmm,长度为105mm。当发电8万千瓦,枯水季节向电网售电价为O.18元/度,其它时间为0.13元/度,反应堆运行经济合理,并能生产民用同位素,并有盈利。元件年卸料量少,现有元件存放池可以存放十五年以上的废元件。
The designed U_3Si-A1, UO_2-Al and U-2 (wt)% zr fuels are 9.763, 4.366 and 17.93 g / cm 3 uranium respectively; the concentrations of U 235 are 1.55% and 2.0 % And O.9%, the maximum fuel consumption were 12658.7,12658.7 and 5000MWD / T respectively. All three components can work at a water temperature of 134 ° C and a heat load of 0.7095 × 10e kcal / m ~ 2 · h. U_3Si-Al and UO_2-A1 elements have good radiation dimensional stability. The U-2 (wt)% Zr element has a diameter of Φ36.2lmm and a length of 105mm after reaching the maximum fuel consumption. When the electricity generation is 80,000 kilowatts, the selling price to the grid during the dry season is O.18 yuan / kWh and the other time is 0.13 yuan / kWh. The reactor runs economically and rationally, and can produce civil isotopes with profitability. Component discharge less in the year, the existing component storage pool can store more than fifteen years of waste components.
