eVinci MCNP input file

AI Thread Summary
An urgent request for an MCNP input file for the Westinghouse eVinci microreactor was made, highlighting the need for proprietary information. It was suggested to contact Westinghouse directly, although it was noted that such details are unlikely to be publicly available. Participants discussed that Westinghouse may not use MCNP for their designs, as vendors often rely on proprietary codes. The NRC might utilize MCNP for verification of vendor analyses. Access to the input file is limited, and proprietary constraints are a significant barrier.

Welcome to PF.

Can you just contact Westinghouse to request the file?

Such details would be proprietary to Westinghouse, and they are unlikely to place such information in the public domain.

A non-proprietary summary presenation to the NRC. Note: the lack of detail.

Pretty sure @berkeman is being facetious. Westinghouse won't *give* you anything. If you buy an eVinci they might let you look at their code decks. In their offices.

I'm not sure that Westinghouse even uses MCNP. Maybe they do, but my experience (in other areas of reactor design) the reactor vendors use their own in-house codes. The NRC may use MCNP to back-check WEC analysis results.

Hello, I'm currently trying to compare theoretical results with an MCNP simulation. I'm using two discrete sets of data, intensity (probability) and linear attenuation coefficient, both functions of energy, to produce an attenuated energy spectrum after x-rays have passed through a thin layer of lead. I've been running through the calculations and I'm getting a higher average attenuated energy (~74 keV) than initial average energy (~33 keV). My guess is I'm doing something wrong somewhere...
