Research Codes

The CCP-NTH Code Repository

CCP-NTH supports a series of community codes that are developed, maintained, or actively used across the UK nuclear thermal hydraulics community.

Overview

The CCP-NTH Code Repository brings together community codes relevant to nuclear thermal hydraulics, including software developed within CCP-NTH and tools widely used by the UK NTH community.

This page provides a central entry point for code access, information, and community contribution.

OpenFOAM logo
Subchannel modelling capability hase been developed for PWR and HTGR within open-source CFD frameworks, including Code_Saturne and OpenFOAM, to support subchannel-scale thermal hydraulics analysis and method development.

Contribution

We encourage members of the nuclear thermal hydraulics community to contribute to the CCP-NTH Code Repository.

To get involved, please create a GitHub account and send us your GitHub username through the Contact page. This helps us coordinate access, contributions, and future community development.
