Abstract
Pyrolytic dehydrochlorination of the electrical cable insulation Hypalon
was studied as a function of time and temperature. The chlorine
evolution was determined separately by means of on-line activity
measurements and by neutron activation analysis in the temperature range
200°C to 300°C, with one test conducted at 500°C. The object of the
research was to determine the chlorine release and the chlorine release
fraction as a function of temperature. The data obtained were needed to
formulate conclusions regarding the release mechanisms of chlorine.
Estimates of the amount of hydrochloric acid released to the containment
building in a severe reactor accident were also calculated. It can be
concluded that the amount of chlorine release from the Hypalon cable is
significant and will have an effect on iodine behavior in a severe
accident.
