What is the Thermal Conductivity of Graphite in Molten Salt Reactors?

AI Thread Summary
The thermal conductivity of graphite in molten salt reactors varies based on its form and density, necessitating specific identification of the graphite type for accurate data. Users are advised to consult research specific to the chosen form of graphite, as values can differ significantly. It is important to note that a range of thermal conductivity values may be encountered, prompting the need for sensitivity analysis or the use of average values in modeling. Additionally, cumulative neutron dose (fluence) can affect the thermal conductivity of graphite. Accurate modeling in RELAP5-3D will require careful consideration of these factors.

I'm currently running RELAP5-3D to model a molten salt reactor and I require the thermal conductivity of graphite. Is there anyone that is aware of this value, or can inform me of a proper resource?

Thanks!

Value varies based on form and density. specify form and look for research on that form. Even then you will probably have a range of values and need to run sensitivity cases or consider an average value.
 
Graphite thermal conductivity also varies with cumulative neutron dose (fluence)
 

Thread 'MCNP6 BURN Card Issue: Zero Burnup for Material in Fuel Assembly'

Hello everyone, I am currently working on a burnup calculation for a fuel assembly with repeated geometric structures using MCNP6. I have defined two materials (Material 1 and Material 2) which are actually the same material but located in different positions. However, after running the calculation with the BURN card, I am encountering an issue where all burnup information（power fraction(Initial input is 1,but output file is 0), burnup, mass, etc.） for Material 2 is zero, while Material 1...

Thread 'Beginner Seeking Help: MCNP6 Burnup Example (OECD-NEA Benchmark)'

Hi everyone, I'm a complete beginner with MCNP and trying to learn how to perform burnup calculations. Right now, I'm feeling a bit lost and not sure where to start. I found the OECD-NEA Burnup Credit Calculational Criticality Benchmark (Phase I-B) and was wondering if anyone has worked through this specific benchmark using MCNP6? If so, would you be willing to share your MCNP input file for it? Seeing an actual working example would be incredibly helpful for my learning. I'd be really...
