Abstract

Effect of Temperature Difference and Control Rod Movement on Neutron Flux Distribution in Nigeria Research Reactor-1 Core

Highlights

  • In a nuclear reactor the neutron in the core of the reactor determines the dynamic behavior of the reactor

  • In water cooled reactor like Nigeria Research Reactor-1 (NIRR-1), which is a Miniature Neutron Source Reactor (MNSR) the predominantly reactivity changes are brought about by change in the moderator and power which result in decrease in reactivity

  • The description of Nigeria Research Reactor-1 (NIRR-1), a tank-in-pool reactor with under-moderation achieved by using a fuel material of highly enriched uranium and light water as moderator and coolant was given in our publications [3,6,8]

Summary

Introduction

In a nuclear reactor the neutron in the core of the reactor determines the dynamic behavior of the reactor. These design consideration were used in order to assess the effect of coolant temperature difference and control rod movement on neutron flux distribution on NIRR-1 core.
