The development and modification of any computer code necessitate assessment and validation of the code. A similar task prevails with the release of the thermal-hydraulic analysis code RELAP5/MOD3. RELAP5/MOD3 has been developed by EG and G Idaho, from its predecessor code RELAP5/MOD2, after identifying certain deficiencies in the latter. The work presented here assesses the RELAP5/MOD3 computer code. The objective of this study is to evaluate the predictions of the RELAP5/MOD2 and RELAP5/MOD3 computer codes, using a model of a full-length, 30-tube once-through steam generator (OTSG). The RELAP5/MOD3 results for the test facility generally show a reasonable agreement with the data for the primary-side temperature profiles. However, the secondary temperature profile predicted by RELAP5/MOD3, at 65% load, compares fairly well with data and is better than the RELAP5/MOD2 results.
