Abstract
In this work the dehydrochlorination of hypalon by
pyrolysis was studied applying online activity
measurements and neutron activation analysis. Temperature
range studied varied from 20TC to 30TC. For comparison
one experiment was conducted at 5000 °C. Object of the
research was to determine the temperature, where the
chlorine release takes place, as well as the chlorine
release fraction. By comparing different experiments
conclusions about the release mechanisms could be made.
Based on the acquired data estimates of the amount of
hydrochloric acid released to the containment building in
a severe accident were also calculated. As a result it
can be concluded, that the amount of chlorine release
from the hypalon cable material is significant and will
have an effect on iodine behaviour in a severe accident.
