[3J10] Monte Carlo method for sensitivity analysis of alpha- and gamma-eigenvalues

*Toshihiro Yamamoto1, Hiroki Sakamoto2 (1. Kyoto University, 2. RADONet)

Keywords:Sensitivity analysis, Monte Carlo method, alpha-eigenvalue, gamma-eigenvalue

Two Monte Carlo methods for sensititivty analysis of alpha- and gamma-eigenvalues are proposed. For alpha-eigenvalue analysis, a two-step method in which the true eigenvalue is k-eff and another method in which the eigenvalue is an alpha itself are available. On the other hand, the two-step method is possible for gamma-eigenvalue analysis.
