AbstractAbstract
[en] The investigations cover the following work: For a defined core heat-up accident in the THTR-300, up-dated design-basis data describing the accident scenario and the release of fission products from the primary loop are chosen to establish a model of the thermohydraulics of the cooling gas escape, and to simulate the cooling gas diffusion into the building and the environment. The retention of fission product aerosols and gas by the containment building is calculated. The retaining capacity for aerosols is calculated to be 75-96%, and that for iodine 95-99%. (orig.)
