In this thesis, firstly, some main models have been checked on their accuracy, and the reliability of MACORS code has been verified by the RELAP5/MOD2 code on five transient conditions for QSNP: loss of flow; loss of offsite power; incontrollable control rod withdrawal; the feed-water temperature increasing and the feed-water lost. The results obtained are very satisfactory. Secondly, MACORS is used to calculate the operating and accident transients for QSNP, and the analysis results are significant to real engineering. And finally for MNRS, MACORS is used to simulate the steady-state natural circulation heat-removed capacity and the transient behaviors from forced circulation to natural circulation. Some important conclusions are obtained by the analysis results.

The entropy-directed algorithm needs manual intervention to construct fault isolation strategy,and it is ofεhigh computation complexity.Theoretical analysis and experimental results illustrate that the entropy indirected algorithm remedies such deficiency. The MFIT of the strategy by this algorithm is about 38% less than that by the entropy- directed algorithm under the assumption of unequal fault rate.

Chapter 8: We discuss the acceleration of multigrid by Krylov subspace approaches, and recognize the reason for slow convergence of algebraic multigrid methods is that error reduction is significantly less efficient for some very specific error components which may cause a few eigenvalues of the algebraic multigrid iteration matrix to be considerably closer to 1 than all the rest. However, the eigenvectors belonging to the few isolated eigenvalues can be expected to be typically captured after only a few conjugate gradient iterations, which accelerate algebraic multigrid algorithms. Theoretical analysis and numerical results of some practical problems show the iterant recombination accelerates algebraic multigrid convergence.

第八章：先介绍用Krylov子空间迭代法加速一般多重网格方法收敛的基本框架，然后紧紧抓住引起代数多重网格方法收敛减慢的根本原因往往是误差减小对几个特别的误差分量不明显，这导致代数多重网格方法的迭代矩阵的几个特征值接近于1，而共轭梯度方法则能比较典型地捕捉属于孤立特征值的特征向量，从而推导出有效的共轭梯度加速算法和程序实现，不仅从一些具体的实际应用例子的数值结果去验证迭代复合加速收敛的效果，而且还从理论上分析了预处理共轭梯度法加速代数多重网格法收敛的机理。
