“…Jeong et al perform simulations using CFDs in order to determine the thermal performance of heat pipes as a passive cooling system to remove residual heat on the nuclear reactor core during an accident. The simulated results show that the heat pipe can be used to reduce the temperature at the reactor core from 290°C to 195.1°C [5].Mochizuki et al have studied the cooling system using a heat pipe loop for a decay heat dissipation system on a BWR reactor core. The evaporator part of the heat pipe loop is located near the reactor core, and the condenser section with fin is located outside the containment.…”

Abstract. After Fukushima Dai-ichi nuclear power reactor accident, spent fuel in spent fuel storage pool (SFSP) became an important thing to pay attention to, due to its decay heat release. If station blackout occurred, the active system for SFSP cooling system will experience malfunction to remove the product of decay heat. To keep spent fuel safe, heat pipe as passive cooling system device can be used to remove spent fuel decay heat even if the active cooling system failed. Heat pipe with 6 m on length will be proposed as apassive cooling system in SFSP. For that, it is necessary to analyze the effect of Graphene nano-fluid as heat pipe working fluid. The objective of this research is to know the effect on Graphene nano-fluid to enhance the heat pipe thermal performance and to know the heat transfer phenomena inside the heat pipe based on Graphene nano-fluid. Graphene nano-fluid with 1% weight concentration was used as working fluid with filling ratio of 80%. The experimental investigation is conducted with varying the evaporator heat load of 1000, 1500, 2000, and 2500 W. Water as coolant flows in thecondenser with aconstant volumetric flow rate of 8 L/min. The experiment results show that there was anovershoot, zigzag and stable phenomena inside the heat pipe. The thermal resistance of heat pipe is obtained at 0.015 o C/W. The use of Graphene nano-fluid as working fluid can enhance the heat pipe thermal performance significantly and can be used as an alternative working fluid in heat pipe for thepassive cooling system in SFSP of nuclear power plant.

“…The maturity of heat pipe technology and the rapid development of nuclear energy technology promotes the application of heat pipe technology in nuclear power engineering [7]. Jeong [8] numerically analyzed the thermal performance of a single hybrid heat pipe under reactor operation conditions. The results shown that the hybrid heat pipe removed 18.20 kW per rod with total thermal resistance of 0.015 K/W.…”

Monitoring and control of the temperature and pressure of water sample are critical issues in the nuclear power engineering for the efficient and safe operation. In this paper, through the thermal and fluid dynamical simulations, we demonstrated the improvement in heat transfer performance of the heat pipes used in the sampling cooler by changing the heat pipe diameters and the fin types. Heat pipes with helical fins show a 30.9% enhancement in heat transfer j factor compared to the smooth heat pipes. Additionally, the numerical results also show that the sampling cooler has an optimal helical fin pitch, which is 140mm.

The thermoelectric application is one of most popular energy harvesting application from waste heat. The thermoelectric generators, thermoelectric coolers, and thermoelectric modular devices criterion comes in both sustainable energy as well as renewability of electrical energy from waste heat sinks. The recovery operations are optimized with the help of modeling using MATLAB software. The material science based thermoelectric applications can be modeled with the help of MATLAB simulink modeling. The numerical and algorithmic method of MATLAB modeling is for the development of hybrid thermoelectric coolers and generators (solar thermoelectric generators, radiative cooler, heat sinks). Later, the use of MATLAB software gives opportunities to develop the cost effective and high power thermoelectric generators. The emerging commercial device making is also discussed for thermoelectric generator using MATLAB optimization.
