Abstract

Abstract

Based on the test method and theory of the removal cross section, the macro and micro removal cross sections of 4 different composites and relative elements have been calculated, and experimentally verified by the relaxation length and transitivity percent. The results indicate that, the tested transitivity values for 4 different composite plates（20 mm） are all 10% higher than those of calculated, which validate the availability and practicability of removal cross section used in the neutron shielding calculation. Finally, the differences and influential factors of calculated values and test values have been analyzed in detail.
