【摘要】 为了分析秦山核电厂的弹棒事故编制了两个程序。一个以有温度反应性反馈的点模型为基础。在这个程序中,弹棒价值是“绝热”近似下得到的。在另一个程序中,用节块格林函数方法解时-空中子动力学方程。用这两个程序计算了秦山核电厂寿期初的两个弹棒例子的堆芯核功率瞬态。更多还原

【Abstract】 Two codes were developed to analyse rod ejection accident for Qin Shan Nuclear Power Plant. One was based ’on poiiit model with temperature reactivity feedback. In this code, the.worth of ejected rod was obtained under "adiabatic" approximation. In the other code, the Nodal Green’s Function Method was used to solve space-time dependent neutron diffusion, equation. Using these codes, the transient core-power have been calculated for two’rod ejection cases at beginning of .core-life in’Qirt Shan Nuclear Power Plant.更多还原
