Abstract:
Reactors are widely used in the nuclear power plant due to the rapid demand
for electricity by reducing the greenhouse effect. However, the effectiveness of
the nuclear reactor depends on an adequate safety system. Hence, temperature
and heat transfer are two critical parameters for any reactor in operation for
which intelligent temperature control with an integrated safety system is
essential. Therefore, the present study has emphasized the development of a
simulated small-scale water-based reactor with intelligent control and safety
system and examined through the analysis of thermal-hydraulic parameters.
Radial heat transfer of an electric rod used as fuel in the primary circuit has
been analyzed by taking sensor reading in various positions of the core. The
developed system is self-controlled with all possible active and passive safety
systems. Consecutively, the prototype has also been designed including manual
adjustment to ensure a fail-safe environment. The system is capable to operate
at temperatures between 80°𝐶 and 120°𝐶, although the design can withstand up
to 200°𝐶. The data of the experiment are taken under the pressure of 200 𝑘𝑃𝑎
at 120°𝐶 temperature. Results show that heat output of 2116.09 𝑘𝐽 has been
obtained from the system against heat input of 2514.80 𝑘𝐽, which gives an
efficiency around 16% of the developed system.
