Abstract
A test capsule for measuring at least one property of a material exposed to nuclear radiation comprises a lattice structure configured to exhibit a change in at least one property responsive to exposure to nuclear radiation. The lattice structure comprises a first strut and a second strut connected to the first strut at a node. Related test capsules and methods are also described.
Claims21
A test capsule for measuring at least one property of a material exposed to nuclear radiation, the test capsule comprising:
- at least one lattice structure configured to exhibit a change in at least one property responsive to exposure to nuclear radiation, the at least one lattice structure comprising:
- a first strut;
- and
- a second strut connected to the first strut at a node.
A test capsule for measuring a change in at least one property of a material responsive to exposure to nuclear radiation, the test capsule comprising:
- a shell defining a volume;
- and
- at least one lattice structure within the volume and configured to exhibit a change in at least one property responsive to exposure to nuclear radiation.
A method of qualifying a material for use in a nuclear reactor, the method comprising:
- placing at least one lattice structure within a test capsule, the at least one lattice structure comprising struts connected to nodes;
- disposing the test capsule in a nuclear reactor and exposing the test capsule to radiation for a duration of time;
- after the duration of time, removing the test capsule from the nuclear reactor;
- and
- measuring a displacement of at least one of the struts of the at least one lattice structure to measure at least one property of the at least one lattice structure.
