Sensitivity analysis of HCLWR

The sensitivity coefficients of neutronic performance parameters in high-conversion LWR cells have been calculate by means of the SAINT code. The difference between sensitivities was investigated for cells with different moderator to fuel volume ratios and different Pu enrichment. The burnup dependence of the sensitivities was also discussed with an emphasis on the effect of fission products on the cell parameters. We have performed the sensitivity analysis for the PROTEUS core. The effect of the difference between the group cross sections obtained by SRAC code from JENDL-2 and ENDF/B-IV on the cell parameters keff, reaction rate ratio and coolant void worth was estimated by considering the cross section changes in the resolved and unresolved resonances of main heavy nuclides, separately. This work was performed as the activity of Working Group on Integral Test for JENDL in JNDC. (author)
