The phrase
"irradiated materials" refers to objects or substances that have been exposed to radiation. Radiation is a type of energy that can cause changes in these materials, either by altering their properties or damaging them.
Full definition
«The atomic structure
of irradiated materials is actually closer to that of a liquid than to that of a glass,» Bauchy said.
Today, most
irradiated materials testing involves designing a material, exposing it to radiation, and destructively testing the material to determine how its performance characteristics change.
«This is quite surprising because glasses and
heavily irradiated materials typically exhibit the same density, so that glasses are often used as models to simulate the effect of the exposure to radiations on materials.»
The RAMS load frame insert has also inspired the development of a tension in - vacuum furnace design for
studying irradiated materials at APS that was developed in concert with the Nuclear Engineering Division at Argonne National Laboratory.
The NAC - LWT is the workhorse for U. S. commercial spent nuclear fuel transportation casks and is currently used for shipment of research reactor spent fuel, nuclear power plant spent fuel assemblies and fuel rods, and
other irradiated materials.
These efforts include installing a 30 - ton detector system (with shielding) in an operating research reactor building as close as 21 feet to the reactor core without affecting HFIR's primary missions of neutron scattering research, isotope production and testing
of irradiated materials.
Strict federal regulation governs the handling of
irradiated materials, from core components to PC boards, which can turn radioactive from particle bombardment.
In contrast, the researchers» results suggest that
irradiated materials are more disordered than glasses.
«Atomic structure of
irradiated materials is more akin to liquid than glass: In a surprising discovery, researchers determine that the atomic structure of irradiated materials is closer to liquid than glass — which may have significant implications for the selection of materials for nuclear applications.»
