TRACE Plug-in
The TRAC/RELAP Advanced Computational Engine (TRACE) code is the latest in a series of advanced, best-estimate reactor systems codes developed by the U.S. Nuclear Regulatory Commission for analyzing transient and steady-state neutronic-thermal-hydraulic behavior in light water reactors. It is the product of a long term effort to combine the capabilities of the NRC’s four main systems codes (TRAC-P, TRAC-B, RELAP5 and RAMONA) into one modernized computational tool.
The TRACE plug-in requires installation of the PARCS plug-in. Please note that the PARCS plug-in will automatically be selected for installation with the TRACE plug-in if you choose to install SNAP directly from the web site. If you download the installation packages to a folder for later installation, the TRACE plug-in will not be available for installation unless you include the PARCS plug-in in your download.
The TRACE Plug-in User's Manual provides instructions for working with TRACE models in SNAP. This Manual is also available as a searchable help set in SNAP.
