RELAP5 AI integrations

No MCP server or agent skill for RELAP5 is listed yet (checked 4 Nov 2026). No MCP server or agent skill exists for RELAP5 or RELAP5-3D as of November 2026. RELAP codes are among the software the US Department of Energy controls: RSICC excludes RELAP from its download delivery, and screens RELAP5/MOD3.3 requests for access through its secure cloud. Any AI integration would have to run inside that controlled environment.

How AI connects to RELAP5

An MCP server or skill can only do what RELAP5 lets programs do. RELAP5 exposes 1 automation interface:

  • Input decks (Input files): RELAP5 models are text input decks, and community projects on GitHub such as input-file generators and plotting scripts work by writing decks and reading output. A skill or files-only server that writes and checks decks is the realistic form of an AI integration. Official RELAP5-3D documentation is hosted by INL, but its site could not be reached from our checker on 4 November 2026, so no link is given here yet.

What INL offers

No AI assistant or MCP server for RELAP5 was found in this check, though INL's and the NRC's sites could not be reached from our checker. RSICC's home page lists RELAP with MCNP, SCALE and VERA as DOE-controlled software administered by the NNSA Office of Nonproliferation and Arms Control, and on 4 November 2026 it carried a notice suspending new licences for that software during a federal furlough.

What an integration for RELAP5 could do

  • Check a RELAP5 input deck for component numbering gaps, unconnected junctions and missing heat structure references before a run.
  • Build a nodalisation table from a deck listing each volume, junction and heat structure with its key dimensions.
  • Turn a transient's plot output into time histories of pressure, flow and cladding temperature and flag when limits you supply are crossed.
  • Generate a set of break-size or boundary-condition variants from a base deck for a sensitivity study.

Know of one, or building one?

If an MCP server or agent skill for RELAP5 exists, tell us and we'll check it and list it. You can also ask for one, which helps builders see demand.

Questions

Is there a RELAP5 MCP server?

No. Nothing was found on 4 November 2026. GitHub projects around RELAP5 are input generators and plotting scripts, not agent integrations.

Can I get RELAP5 to try an AI integration?

Only through the controlled channels. RSICC handles RELAP5 requests, doesn't deliver RELAP by download, and screens RELAP5/MOD3.3 requests for its secure cloud.

AI-generated models, drawings and results must be checked by a qualified engineer before use.
