What temperature does molten corium burn at?

In summary, the exact temperature at which molten corium burns is unclear and debated among experts. However, it must be extremely hot in order to burn through thick layers of steel and concrete. Factors such as the melting point of UO2, steel, and iron oxide, as well as eutectic reactions and the presence of coolant, can all affect the burning temperature. Some sources suggest a range of 2800°C to 3000 K as the upper limit for burning temperature.

What temperature (in Fahrenheit) does molten corium burn at?

Anything hot enough to burn through thick layers of steel and concrete must be insanely hot.

Your question is unclear. What is "corium"?

My bad - should have used Google :(

Why would one expect corium to burn?

UO2 melts around 2800°C. Steel melts at around 1450-1500°C. Iron oxide has a melting temperature of 1377 °C. Corium would probably be somewhere in between. Metals may flow below melting temperature.

Some folks assume 3000°C, and others state 3000 K. The latter would be a better upper limit.

The situation is complicated with eutectic reactions.

And of course, it depends on the presence of coolant (water) and the pressure, which would provide some means of heat transfer.
 

1. What is molten corium and how is it formed?

Molten corium is a mixture of materials that is produced during a nuclear reactor meltdown. It is formed when the nuclear fuel rods become overheated and melt, releasing a combination of uranium, zirconium, and other materials into the reactor's core.

2. What temperature does molten corium burn at?

Molten corium can burn at temperatures as high as 2800°C (5072°F). This extreme heat can cause damage to the reactor and surrounding structures, making it difficult to contain and control.

3. What are the dangers of molten corium?

The main danger of molten corium is its ability to release radioactive materials into the environment. This can lead to contamination of air, water, and soil, which can have serious health consequences for humans and wildlife. Additionally, the extreme heat can cause damage to the reactor and surrounding structures, making it difficult to contain and control.

4. How is molten corium contained and cooled?

Molten corium is typically contained by a structure called a "core catcher," which is designed to catch and cool the molten material. Water is then used to cool the corium and solidify it, creating a solid mass that is easier to handle and dispose of.

5. What happens to molten corium after a nuclear reactor meltdown?

After a nuclear reactor meltdown, the molten corium is typically left in its containment structure until it cools and solidifies. It is then removed and stored in a secure location for long-term storage and disposal. The surrounding area may also need to be decontaminated to prevent any further release of radioactive materials into the environment.
