High-temperature plumbing and advanced reactors
The use of nuclear fission power and its role in impacting climate change is hotly debated. Fission advocates argue that short-term solutions would involve the rapid deployment of Gen III+ nuclear reactors, like Vogtle-3 and -4, while long-term climate change impact would rely on the creation and implementation of Gen IV reactors, “inherently safe” reactors that use passive laws of physics and chemistry rather than active controls such as valves and pumps to operate safely. While Gen IV reactors vary in many ways, one thing unites nearly all of them: the use of exotic, high-temperature coolants. These fluids, like molten salts and liquid metals, can enable reactor engineers to design much safer nuclear reactors—ultimately because the boiling point of each fluid is extremely high. Fluids that remain liquid over large temperature ranges can provide good heat transfer through many demanding conditions, all with minimal pressurization. Although the most apparent use for these fluids is advanced fission power, they have the potential to be applied to other power generation sources such as fusion, thermal storage, solar, or high-temperature process heat.1–3

Inertial Confinement Fusion experiments are conducted in polymer capsule in which nuclear products are located. The polymer capsule is based on polystyrene polymer and are obtained by using a triphasic emulsion process. The capsule characteristics mainly depend on the number average molecular weight, the molecular weight dispersity and finally the atomic composition. It has been shown that the surface quality of capsule is directly connected to the polydispersity index. The best results have been obtained by using polystyrene which exhibited polydispersity index inferior to 1.20. The aim of this study is to develop organometallic polymers by using living radical controlled polymerization process in order to control physical properties and final composition.
