Study of multiplication factor sensitivity to the spread of VVER spent fuel isotopics calculated by different codes.
Original language description
As a sensitivity study the impact on the system reactivity was studied in the case that different calculational methodologies of spent fuel isotopic concentrations were used for VVER spent fuel inventory computations. The sets of isotopic concentrationsobtained by calculations with different codes and libraries as a result of the CB2 international benchmark focused on VVER-440 burnup credit were used to show the spread of the calculated spent fuel system reactivity. Using the MCNP 4B code and changingthe isotopics input data, the multiplication factor of an infinite array of the VVER-440 fuel pin cells was calculated. The evaluation of the results shows the sensitivity of the calculated reactivity to different calculational methodologies used for theIn the studied cases of the CB2 benchmark, the spread of the reference k-results relative to the mean was found less or about ?1% in spite of the fact that the data of isotopic concentrations were spread much more.
