[en] This manual provides users of the Transient Reactor Analysis Code (TRAC) with information about computer codes that can be used to support their analysis efforts. These codes are collectively referred to as TRAC support software. Specifically, documentation is provided to allow users to implement, apply, and interpret the output of the support software that is available. The TRAC code is an advanced best-estimate code for analyzing transients in thermal-hydraulic systems. Considerable input data are required for modeling a large thermal-hydraulic system and considerable output data are produced from the computer calculation for analysis: the support software assists users in their management of both the input and the output data. The four codes described are central to the efficient and effective use of the TRAC code. EXCON is a TRAC graphics file postprocessor that converts the TRAC graphics output files into component-oriented input data files for use with TRAP. TRAP is an extensive plotting package that allows users to produce a range of plots from quick draft-quality graphs for fast examination of results to final presentation-quality graphics for more formal documentation requirements. Extract is a powerful support code that reads a TRAC dump file and generates ''extracted information'' for building TRAC input decks with the latest values for system conditions. EXTRACT is particularly useful and cost effective for analyses that require multiple parametric calculations. CVRT converts TRAC-PF1/MOD1 and early-version MOD2 input decks into current TRAC-PF1/MOD2 input decks
