【Abstract】 The first order perturbation theory is used to calculate the sensitivity profile of K eff in fast facility. The calculated formulas are given in the sphere co ordinate. As an example, the sensitivity profiles of K eff to ,σ n,f and σ n,γ of GODIVA and ZPR 6/7 are all calculated. The results are also compared with those of FORSS. The calculation results have correct physical meaning and are reliable for application in the actual benchmark review.更多还原
