AI Thread Summary
The discussion revolves around a user's difficulties in using MCNP to create an input deck for calculating fluence in a zinc sulphide scintillator, specifically with alpha particles from a plutonium solution. Key concerns include uncertainty about geometry, the correct input for the cell card regarding alpha particles, and confusion over ZAID numbers and the SDEF card for a volume source. The user seeks assistance but expresses frustration over a lack of support from peers at their university. The thread concludes with the user deciding to leave the forum, indicating a sense of defeat in finding help. Overall, the conversation highlights challenges faced by students in complex computational tasks without adequate guidance.

I don't have anyone in my university who can help me with MCNP. I'm trying to write an input deck to calculate fluence in a zinc sulphide scintillator. The alpha particles are being emitted from a solution containing plutonium, plutonium nitrate and plutonium nitride.

There are lots of things I don't understand. I am not sure if my geometry is correct. I am not sure what to put in the cell card for alpha particles "imp:?". I am unsure about the ZAID numbers and the SDEF card for a volume source. Any help to get this working would be appreciated :frown:

Hi,
I think that I I had answered of some of your question in "inbox" but I see that you ask the same question
I will wait the reponse that you will have with this new post
bye

Hi,

I don't think you added anything new in the inbox reply?

First I would like to address the cell and surface cards. I think my geometry is correct, but is it confusing?

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...
