Studi Perhitungan Laju Reaksi Neutron Dalam Reaktor SCWR (<i>Supercritical Water Reactor</i>) Model Perangkat (Assembly) Heksagonal Berbahan Bakar Thorium

Abstract

The calculation of fission and capture reaction rate with and without filter has been done using REACT of SRAC. In material 1 fission reaction rate with and without filter were increased by increasing percent of U²³³. The highest fission reaction rate with filter was 5,7194x10^-2reaction/cm³sand without filter was 6,1361x10^-2 reaction/cm³s. Meanwhile capture reaction rate with and without filter were decreased by increasing percent of U²³³. The highest capture reaction rate with filter was 2,2156x10^-2 reaction/cm³s and without filter was 2,4906x10^-2 reaction/cm³s. In material 3, fission and capture reaction rate with and without filter were decreased by increasing percent of U²³³ in material 1. The highest fission reaction rate with filter was 1,5218x10^-2 reaction/cm³s and without filter was 1,6293x10^-2reaction/cm³s. The highest capture reaction rate with filter was 2,2156x10^-2 reaction/cm³s and without filter was 2,3993x10^-2reaction /cm³s. Neutron reaction rate with filter was smaller than neutron reaction rate without filter
