Abstract
This project aims to develop thermoelectric generators (TEG)-based devices for sensing during normal and off-normal conditions in Small Modular Reactors (SMRs). Locations such as reactor core vessels, steam generators, housings of pumps, heat exchangers, and steam pipe housings in primary loop and secondary loop are potential installation sites. The heat is conducted through an adaptor to the TEGs and removed by a heat sink by means of natural convection. The electrical power generated by the TEGs is then used to drive sensors and wireless communications. Additional power can be stored in batteries or in super capacitors for emergency operations. The sensing system measures important data such as temperature, flow rate, and radiation dosage. Several experiments including the TEG test and lab-based experiment were conducted to validate the simulation and assumptions. The prototype that attaches to a 12 in. nominal size schedule 80 pipe was at 300 °C. A large natural convection heat sink is applied as the cooling solution. A thorough thermal analysis was made to assure that the heat sink temperature was below 80 °C and the TEGs temperature difference was around 100 °C. An enclosure was also presented to protect the electrical components from harsh condition. | This project aims to develop thermoelectric generators (TEG)-based devices for sensing during normal and off-normal conditions in Small Modular Reactors (SMRs).
