Model experiments BERDA describing the impact of molten core material against a PWR vessel head

  • 1. Institut fuer Reaktorsicherheit, Karlsruhe (Germany)

Description

The experiments investigate mechanical effects of a postulated in-vessel steam explosion. The geometry including the liquid slug and the vessel head is scaled down 1:10. Six tests are reported, two tests with a slug of lead spheres, one test with a solid projectile, and three tests with slugs of liquid metal. The results indicate that for slugs of lead spheres and liquid metal the impact forces are reduced to about one quarter of the force caused by a solid projectile. In those tests where the load carrying capacity was approached, maximum strains of more than 30 % were obtained. 6 refs., 7 figs
