PROJECT TOPICS AND MATERIALS ON THERMAL POWER CALIBRATION OF NIGERIA RESEARCH REACTOR-1 BY CALORIMETRIC AND HEAT BALANCE METHODS
ABSTRACT
This research work presents the results of the thermal power
calibration of Nigeria Research Reactor-1 (NIRR-1), a low power
Miniature Neutron Source Reactor (MNSR), using calorimetric and heat
balance methods. The calibration was performed at two different power
levels: half power (15kW) and full power (30kW). The calorimetric method
involved operating the reactor at a constant power and isolating
coiling system to avoid cooling of the pool water. For this method, the
reactor pool temperature rise with time was measured, the reactor heat
capacity constant was calculated and the heat losses from the reactor
pool to the environment were evaluated. The power was then evaluated as a
function of temperature-rise rate. The total thermal power is the sum
of heat losses from the reactor pool to the environment and the power
calculated as a function of temperature-rise rate. The heat balance
method consisted of the steady state energy balance of the cooling loop
of the reactor. For this method, the measurement of the inlet
temperature, outlet temperature and temperature difference were carried
out and also flow-rate of the coolant passing through the core was
determined. The heat losses were evaluated and the values added to the
power calculated as a function of flow rate and temperature difference
gives the total thermal power. The Average water temperature rise during
these experiments were: (29.5 to 32.0)oC and (27.0 to 29.6)oC for
calibration at half and full power levels respectively .The thermal
power obtained by the calorimetric method at half and full power were:
(15.8±0.7) kW and (30.2±1.5) kW respectively. For heat balance method,
the values of the thermal power obtained at half and full power were:
(15.2±1.2) kW and (30.7±2.5) kW respectively. It was observed that the
calorimetric method is more accurate with deviations of only 4% and 5%
for calibrations at half and full power respectively. It is therefore
recommended that the calorimetric method should be adopted for routine
thermal power calibration of NIRR-1.
CHAPTER ONE
INTRODUCTION
1.1 INTRODUCTION
Fuel burn-up was shown to be linearly dependent on the reactor
thermal power (Podvratnik, 2011). It is therefore obvious that the
reactor thermal power calibration is very important for precise fuel
burn-up calculation. The reactor power can then be determined from
measuring the absolute thermal neutron flux distribution across the core
in horizontal and vertical planes (Musa et al., 2012). It has
also been established that flux distributions can be measured with
activation of cadmium covered and bare foils irradiated at steady
reactor power (Souza, 2002). But Shaw (1969) demonstrated that this
method consumes a lot of time and is not accurate. It can therefore be
said that the foil activation method is most suited for zero power
reactors and seldom applied to bigger reactors. In the case of high
power reactors in which a temperature rise across the core is produced
and measured then a heat balance method is the most common and accurate
method of determining the power output of the core (Mesquita et al., 2007).
Accurate reactor thermal power calibration is important for: safe
monitoring and evaluation of reactor dynamic behavior, determination of
fuel burn-up and normalization of neutron fluxes and dose rate.
(Mesquita et al., 2007; 2009; 2011, Podvratnik, 2011). Power
excursion of any reactor is of great concern to reactor physicist for
safe operation reasons. As power is related to the neutrons population
and to the mass of fissile material present, its measurement is
essential to the safe control and operation of the reactor as well as
the reliability of the research reactor (DOE, 1993, Podvratnik, 2011).
It therefore became imperative to undertake power measurements and
calibration from time to time to establish.
