Macroscopic Examination Of The Nuclear Data Sensitivity Analysis Study

Two problems related to the nuclear data benchmark test are concerned in this thesis.The first-order perturbation theory is used to the sensitivity profile of the K_eff in the fast facility. The calculated formulas are given in the sphere co-ordinate. As the example, the sensitivity profile of the K_eff to the (?),σ_n,f and σ_n,γ of the GODIVA and ZPR-6/7 are all calculated. The results are also compared with the results of the FORSS. The Uncertainty analysis formulas are also given in this paper.We investigate the adequacy of the available ²³³U cross-section of the CENDL for calculation of the fast experimental critical system. The fast facilities are used in our work. The K_eff and the central fission-rate-ratio,cfr_[²³⁵U]^[233U], are calculated. By the comparison of the results between the CENDL and ENDF/B, some advises are given to improve the evaluation of the ²³³U cross-section of the CENDL.
