共振自屏计算是反应堆物理计算的基本环节,它直接影响到反堆物理的计算精度。传统的组件程序(如WIMS、TPFAP等)大多采用等价原理,通过Bell因子和丹可夫因子进行共振能区的有效截面的计算。由于所谓的“等价”算法,该方法对非均匀性较强、含多种共振核素的复杂几何情况下有很大的局限性,该方法仅限于均匀系统、 Resonance self-screen calculation is the basic part of the reactor physics calculation, which directly affects the calculation accuracy of the anti-pile physics. Traditional component programs (such as WIMS, TPFAP, etc.) mostly adopt the principle of equivalence, and calculate the effective cross-section of the resonance energy region by the Bell factor and the Dankoff factor. Due to the so-called “equivalence” algorithm, this method has great limitations for complex geometry with many heterogeneous heterogeneities and multiple radionuclides. This method is limited to a homogeneous system,
