Sensitivity Analysis of Spent Fuel Storage Burnup-Credit Calculation

To analyze the burnup credit,it is necessary to calculate the reactive systems of spent fuel. Besides,in order to ensure the nuclear critical safety,it is also necessary to ensure the envelope sex of the results analyzed,requiring taking into account the effect of results caused by a variety of fuel consumption factors. Employing STARBUCS module of the SCALE program package,the writer has reached beneficial conclusions by analyzing the sensitivities of the nuclear critical safety of spent fuel storage system as a result of factors,such as different trust scales and core operating parameters by means of verifying Phase-IA and Phase-IIA benchmark problems released by OECD / NEA.
