    Fusion Inertial
AI Thread Summary
Inertial fusion's viability as an energy source is questioned due to the minimal amount of matter fused. A professor suggested performing calculations to understand the process better. The discussion highlights the importance of knowing the gas pressure inside the fusion pellet, which can be estimated using the standard gas law if the mass is known. It was noted that each pellet has a 45% burnup rate, a mass of 1 mg, and a gain of 150, requiring 1 MJ of energy for explosion. Understanding these parameters is crucial for evaluating inertial fusion's potential.

I asked one of the professors in the nuclear engineering department recently how inertial fusion could be a viable energy source if so little matter was fused. He told me that I would be suprised and said that I should do the calculation myself. I found the volume of the pellet, but now I have the problem of finding the pressure of the gas inside it. Does anyone know what it is?

If you know the mass of the gas inside, you can use the standard gas law as a good approximation. If you don't know the mass, there is no solution.

" Each pellet has about a 45% burnup rate, is cyrogenic and multilayered,
and has a mass of 1 mg."
or
"Each pellet has a gain of 150, and the target requires 1 MJ of energy for
explosion. The fuel is burned at a rate of 20 pellets per second."

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...
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...
