Kjernehylse

Kjernehylse refers to a component used in certain types of nuclear reactors. Its primary function is to contain and provide structural support for the nuclear fuel elements, often referred to as fuel rods or fuel assemblies. The kjernehylse is designed to withstand the high temperatures and intense radiation within the reactor core. It also plays a role in controlling the flow of coolant through the core, ensuring that the heat generated by nuclear fission is effectively removed.

In some reactor designs, the kjernehylse may be a single, monolithic structure, while in others, it can be composed of multiple sections or individual tubes. The materials used for kjernehylse construction are carefully selected for their resistance to corrosion and neutron absorption, as well as their mechanical strength. Common materials include stainless steel alloys or zirconium alloys. The precise design and composition of the kjernehylse are critical for the safe and efficient operation of a nuclear reactor. It contributes to maintaining the geometry of the fuel within the core and preventing fuel rod movement.
