abstract
A steady-state analysis of 30-tube Once-Through Steam Generator (OTSG) has been performed on RELAP5/MOD3 and RELAP5/MOD2 computer codes, for 100%, 75%, and 65% loads. Results obtained are compared with experimental data. It is observed that the RELAP5/MOD3 results for the test facility generally show reasonable agreement with the data, for the primary side temperature profiles. The secondary temperature profile predicted by RELAP5/MOD3, at 75% and 65% loads, show a fairly good agreement with data and is better than the RELAP5/MOD2 results. However, the RELAP5/MOD3 calculated secondary temperature profile does not compare well with the 100% load data.
