Analytische und phaenomenologische Auswertung von UPTF-Versuchen und eines SCTF-Versuches Abschlussbericht

Within the framework of the arrangement on the safety research participation and the technical exchange among the Unites States, Japan, and the Federal Republic of Germany (2D/3D-Program) the BMFT is sponsoring experimental and analytical investigations of thermalhydraulic phenomena during a loss-of-coolant-accident of a pressurized light water reactor. The tasks of the research program BMFT No. 1500808 are the parallel and complementary, analytical and experimental investigations of phenomena during the end of blowdown, the refill and the reflood phases of a LOCA, to assist the development of advanced computer code systems. The program consists of the following items: - A contribution to qualify the available data of measurements of UPTF-tests. - The evaluations of phenomena of UPTF 'separate effects' tests as well as UPTF integral tests under the assumption, that only cold leg ECC injection systems are available. - Post test calculations of two selected UPTF 'separate effects' tests by using the GRS code system ATHLET. - The evaluation of phenomena of one SCTF-integral test under the conditions of combined ECC injection. - The post test calculation of this SCTF-integral test by using the ATHLET-FLUT code. - A contribution to the final report of the 2D/3D-program.
