摘要：

This paper describes experiments to understand the behaviour of nuclear reactors' thermo-hydraulic parameters allow improved model predictions, contributing to their safety. The Nigeria Miniature Neutron Source Reactor called Nigeria Research Reactor-1 (NIRR-1) is a tank-in-pool type reactor with 90.2% enriched uranium as fuel, and light water as moderator and coolant. The core is cooled by light water natural convection. The reactor core assembly, surrounded by beryllium reflectors, is located at the bottom of the reactor vessel. The NIRR-1 has no installed device to measure the core mass flow rate. In this work, experiments were performed at different power levels to monitor some thermo-hydraulic parameters like core mass flow rate, coolant velocity, mass flux, density and Reynolds number in the core of NIRR-1. These experiments confirm the efficiency of natural circulation in removing the heat produced in the reactor core by nuclear fission. Copyright © 2015 Inderscience Enterprises Ltd.
