Abstract

LiH;
yoğunluğu, yüksek nötron yakalama tesir kesiti ve yüksek sıcaklıklarda
kullanılmasına imkân veren fiziksel-kimyasal özellikleri sayesinde nötron
moderasyonunda oldukça yaygın kullanılan bir moderatör malzemedir. Güçlü bir
benzetim programı olan GEANT4 ile LiH’in nötron moderatörü olarak kullanıldığı
bir ortam için düşük enerjili nötronların ve üretilen izotop-parçacıkların
hadronik etkileri araştırılmıştır. Ek olarak, LiH malzemesi için düşük nötron
akısında, enerji birikimi hesaplanmıştır

Geant4 Simulation of Hadronic Interactions for the Reactor Moderator Material LiH

Abstract

LiH
is one of the most common moderator materials for neutron moderation; due to
its high density, high neutron capture cross section and physical-chemical
properties that provides usage at elevated temperatures. Hadronic interactions
of low energetic neutrons and generated isotopes–particles have been investigated
for a situation in which LiH was used as a neutron moderator by using GEANT4,
which is a powerful simulation software. In addition, energy deposition along
LiH material has been calculated at low neutron flux

Keywords

Nuclear reactor, moderator material, hadronic interactions, Geant4, lityumhydride
