Steam blowdown in the HDR-containment results and final evaluation of the open and blind containment standard problem

The objectives of a standard problem are the systematic comparison between experimental and analytical results in various fields of reactor safety and the assessment of the resulting differences. On the basis of the HDR containment experiment V44, the blind German Standard Problem No. 6 and the open International Standard Problem No. 16 were carried out. This paper presents the major findings of both standard problems and the differences observed when comparing the blind and open results
