Method of removing the decay heat of radioactive fission products

Creators

Description

In case of complete depressurization of the THTR-300, fully demineralized water, enriched with boron, is sprayed on the core from above. This method can also be applied for afterheat removal on failure of the steam generators. The recondensed water flows downward and is removed by means of a sphere discharge tube on drain pipes. (DG)

Abstract (German)

Bei voelligem Kuehlgasverlust im THTR-300 wird vollentsalztes, mit Bor angereichertes Wasser von oben auf das Core gesprueht. Diese Mehtode ist auch bei Ausfall der Dampferzeuger zur Abfuhr der Nachwaerme verwendbar. Das wiederkondensierte Wasser wird ueber ein Kugelabzugsrohr bzw. Entwaesserungsrohre nach unten abgezogen.
