Discussion Overview

The discussion revolves around the request for an MCNP input file for the Westinghouse eVinci microreactor. Participants explore the feasibility of obtaining such a file, the proprietary nature of the information, and the potential use of MCNP in reactor design.

Discussion Character

  • Debate/contested
  • Technical explanation

Main Points Raised

  • One participant urgently requests an MCNP input file for the eVinci microreactor.
  • Another participant suggests contacting Westinghouse directly to request the file.
  • A later reply indicates that the requested details are likely proprietary and not publicly available.
  • Participants discuss the possibility that Westinghouse may not use MCNP, suggesting that reactor vendors typically utilize their own in-house codes.
  • It is mentioned that the NRC may use MCNP to validate analysis results from Westinghouse.

Areas of Agreement / Disagreement

Participants express differing views on the availability of the MCNP input file and the likelihood of Westinghouse providing such proprietary information. There is no consensus on whether Westinghouse uses MCNP for their reactor designs.

Contextual Notes

The discussion highlights uncertainties regarding the proprietary nature of the input file and the specific software used by Westinghouse in reactor design. There are assumptions about the availability of information and the practices of reactor vendors.

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.
