Corium: meaning, definitions and examples

Biologically, it can also refer to the dermis, which is the layer of skin beneath the epidermis, in medical contexts.

• The tattoo ink penetrates into the corium, making it permanent.
• Deep cuts that reach the corium usually require stitches to heal properly.

Specifically used to describe the highly ionized gas present in the sun and other stars. It is part of discussions about solar phenomena like solar flares and coronal mass ejections.

• Solar plasma can be ejected during a coronal mass ejection, affecting satellites.
• The sun's core is composed of incredibly hot solar plasma.

General physics and astronomy use this term to describe gas in which some or all of the atoms are ionized, meaning they have lost or gained electrons. It is less specific than 'plasma' and can refer to a variety of gases in different conditions.

• The ionized gas in the nebula emits light at various wavelengths.
• A strong electric field can turn the surrounding air into ionized gas.

Typically used in scientific and technical contexts to describe the highly radioactive material created in a nuclear reactor during a meltdown. It is a mix of nuclear fuel, fission products, control rods, and structural materials.

• The team faced significant challenges in removing the corium from the reactor after the accident.
• Corium's unique properties require specialized techniques for handling and disposal.

Used in general discussions about the remnants of nuclear fuel after an accident or partial meltdown, emphasizing the debris-like nature and the need for cleanup.

• The cleanup crew was tasked with removing the nuclear fuel debris from the reactor site.
• Scientists are studying the composition of nuclear fuel debris to understand the accident's effects better.

Refers more broadly to any material within the reactor core, including but not limited to fuel, structural components, and control elements. It can be used both in normal operational contexts and in discussions of accidents.

• The maintenance team inspected the reactor core material for signs of wear and tear.
• A detailed analysis of the reactor core material was conducted after the incident.
