The computer program TSPEC was developed to provide a relatively simple, approximate analysis for predicting the performance of gas-cooled fast breeder reactor (GCFR) model core assemblies in the core flow test loop (CFTL). The test specifications will list the steady-state and transient input parameters, including the time functions of power and flow for each test run; TSPEC will predict the resultant test parameters. The code performs four types of calculations: (1) geometric bundle data; (2) geometric bundle data and prediction of N steady-state runs; (3) geometric bundle data and prediction of a series of steady-state runs, with linear interpolation between the first and last input values; and (4) geometric bundle data and N transient runs. The structure of the code is explained and the following user information is provided: input instructions, sample calculations, a code listing, and an index of code variables. Further development of the code is required to provide the complete range of CFTL information.
