RETRAN-02 represents a significant achievement in the development of a versatile and reliable computer program for use in best-estimate transient thermal-hydraulic analysis of light water reactor systems. The RETRAN-02 computer program is an extension of the RETRAN-01 program designed to provide analysis capabilities for (1) BWR and PWR transients, (2) small break loss of coolant accidents, (3) balance of plant modeling, and (4) anticipated transients without scram, while maintaining the analysis capabilities of the predecessor code. The RETRAN-02 computer code is constructed in a semimodular and dynamic dimensioned form where additions to the code can be easily carried out as new and improved models are developed. The NRC, at the request of a group of utilities, had Argonne National Laboratory perform a technical review of RETRAN-01 MOD003 and RETRAN-02 MOD002. This review was completed in May 1983, and the NRC issued a Safety Evaluation Report on RETRAN in September 1984. Revision 4 of the RETRAN-02 computer code manuals describes the MOD005 version of the code. This report (the first of a four-volume computer code manual) describes the theory and numerical algorithms of the RETRAN-02 code. The three companion volumes describe the programming details, the user input requirements and sample problem input and output files, and the verification and qualification performed with RETRAN. 186 refs., 75 figs., 30 tabs.
