[en] The report presents the results of a preliminary analysis of the data from Semiscale Mod-3 Test S-07-3. Test S-07-3 was the third blowdown-refill experiment conducted in the Semiscale Mod-3 baseline test series (Test Series 7). The test was conducted from an initial pressure of about 15.6 MPa, a core inlet temperature of 557⁰K, and a core temperature rise of about 37⁰K. The steady-state core power was 2 MW and the core contained 23 powered rods and 2 unpowered rods (one of the rod locations contained a liquid level probe). A flat radial power profile was used for this test. The objectives of Test S-07-3 were to evaluate the effects of the location of the system pressurizer (intact loop versus broken loop hot leg) and to assess the effects of containment pressure on the end of blowdown conditions. These objectives were met by comparing results from Tests S-07-3 and S-07-1. The containment pressure for the two tests was 136 kPa and 241 kPa, respectively
