Welcome to the ARIANT Home Page

 

ARIANT (AlgoRIthm for Analysis of Network Thermalhydraulics) home page is intended for all CNL staff who develop, validate, and use the code or the output from it.

ARIANT is a generalized network thermalhydraulics modelling tool. It can simulate two-phase flows and heat transfer over a wide range of temperature and pressures, including both sub- and supercritical pressures. The primary focus of development has been on the analysis of the consequences of postulated upset scenarios in CANDU reactors. The code has also been successfully applied to a wide range of problems from test facilities (e.g., RD-14M, CWIT, LOBI, etc.). ARIANT is currently being revised to support applications in Small Modular reactors such as the molten salt or the high temperature, gas cooled reactors.

An ARIANT training course has been scheduled. See the Training page for more information.

ARIANT is being developed by the Systems and Safety Analysis Branch (SSAB) of the Nuclear Engineering and Systems Analysis Division (NESA), which is part of the Research and Development (R&D) unit of CNL.
