LOFT suppression tank initial conditions and predicted performance for the L2 (power ascension) test series
Description
The LOFT suppression tank will successfully simulate a large pressurized water reactor (LPWR) containment response if the initial tank conditions are: 127 cm (50.0 in.) tank liquid level, 82.80C (1810F) initial tank temperature, and 1.1 KPa (0.16 psig) initial tank pressure. There should be complete condensation of the blowdown fluid with an end of blowdown subcooling in the condensing pool of 11.10C (200F). Based on previous experience and suppression system research conducted in Germany, there should be no excessive tank loading occurring during any portion of the blowdown. The primary system mass and energy releases to containment are similar for reduced and full power tests, so the same initial suppression tank conditions can be used for the entire L2 test series. This analysis is limited to a comparison of the full double-ended cold leg break at various power levels
