Abstract
S/U analysis has been performed with a Monte Carlo code MCS for TMI-1 PWR pin-cell problem in the UAM benchmark. The sensitivity coefficients of k-inf and one group microscopic cross sections are compared between MCS and SERPENT2. The sensitivity results show a good agreement. The uncertainties are calculated with 44 group covariance data libraries from ENDF/B-VII.1 and SCALE 6.1. The top contributors of uncertainties are also calculated.
