TY - UNPB N1 - Unpublished TI - Impact of nuclear data uncertainties in the Phase-1B Benchmark N2 - Accurate control over the spent nuclear fuel content is essential for its safe and optimized transportation, storage and management. Consequently, the reactivity of spent fuel and its isotopic content must be accurately determined. Nowadays, to predict isotopic evolution throughout irradiation and decay periods is not a problem thanks to the development of powerful codes and methodologies. In order to have a realistic confidence level in the prediction of spent fuel isotopic content, it is desirable to determine how uncertainties in the basic nuclear data affect isotopic prediction calculations by quantifying their associated uncertainties ID - upm11235 PB - American Nuclear Society EP - 370 JF - Transactions- American Nuclear Society UR - http://www.new.ans.org/ VL - 104 A1 - Cabellos de Francisco, Oscar Luis A1 - Martínez, J.S.
