ORNL to partner with Type One, UTK on fusion facility
Yesterday, Oak Ridge National Laboratory announced that it is in the process of partnering with Type One Energy and the University of Tennessee–Knoxville. That partnership will have one primary goal: to establish a high-heat flux facility (HHF) at the Tennessee Valley Authority’s Bull Run Energy Complex in Clinton, Tenn.

During the course of a hypothetical severe accident in a nuclear power plant, spray may be activated in order to reduce static pressure in the containment. The Institut de Radioprotection et de Sûreté Nucléaire (IRSN) has developed the TOSQAN experiment to provide a better understanding of the heat transfer and mass transfer that take place between a spray and the surrounding confined gas in such a situation. This paper studies how the temperature of the spray at the injection point influences the dynamics of a test. To carry out this analysis, we performed two spray tests: spray test 101 (ST101), which served as a reference, and spray test 107 (ST107), which had exactly the same initial and boundary conditions except for the temperature of the spray at the injection point, which varied from 25°C to 58°C. First, we present the entire scenario for ST101 and ST107 and the results of the tests. We then focus our analysis on the intercomparison of the thermal-hydraulic behavior induced by the spray temperature at the injection point and the wall temperature. This intercomparison is divided into two parts: global and local.
