Abstract
The effect of volatile ruthenium release in a case a
reference BWR nuclear plant was studied to get
rough-estimates of the effects on the spreading of
airborne ruthenium inside the containment and reactor
building and the fission product source term. The
selected accident scenario starting during shutdown
conditions with pressure vessel upper head opened was a
LOCA with a break in the bottom of the RPV. The results
suggest that there is a remarkable amount of airborne Ru
in the containment atmosphere, unlike with the standard
MELCOR Ru release model which predicts no airborne Ru at
all in the selected case. Based on the performed plant
scoping studies it seems reasonable to take the release
of volatile ruthenium oxides into account when assessing
source terms for plants during shutdown states.
