Abstract
A getter element includes a getter material reactive with a fission product contained within a stream of liquid and/or gas exiting a fuel assembly of a nuclear reactor. At least one transmission pathway passes through the getter element that is sufficiently sized to maintain a flow of the input stream through the getter element at above a selected flow level. At least one transmission pathway includes a reaction surface area sufficient to uptake a pre-identified quantity of the fission product.
Claims16
A getter element comprising:
- a getter body including a getter material reactive with a nuclear fission product, the getter body further including a void structure through the getter material forming at least one through-channel to facilitate a flow of an input stream through the getter body, the void structure formed by removal of a plurality of void forming structures that were mixed with the getter material in the getter body.
A getter element comprising:
- a getter body including a first getter material reactive with a first nuclear fission product, the getter body including a second getter material reactive with a second nuclear fission product, the getter body further including a void structure through the first getter material and the second getter material that forms at least one through-channel to facilitate a flow of an input stream through the getter body, the at least one through-channel comprising a plurality of substantially-spherical voids formed by removal a plurality of void forming structures that were mixed with the first getter material in the getter body.
