[1M17] Sensitivity analysis for the new STACY with JENDL-5 library
キーワード:New STACY, sensitivity, JENDL-5, Serpent
A previous study showed observable keff differences in the new STACY analyses when using JENDL-4.0 and JENDL-5. Which isotopes and reactions contribute significantly to this difference is an essential issue for experimental designs of the new STACY. In this research, the sensitivity coefficients of keff due to the cross-section perturbation for the new STACY with JENDL-5 were estimated by the Serpent code to indicate the significantly contributed nuclides and reactions.
The calculated results showed that 235U, 238U, 16O, 1H and the S (α, β) contribute significantly on the difference between new STACY analyses with JENDL-4.0 and JENDL-5.
