The release of iodine in the LOCA simulation experiment ISOLDE
The ISOLDE project (Iodine Solubility and Degassing Experiment) consisted of five simulations of a loss of coolant accident (LOCA) in a pressurised water reactor. The results of accident investigations and experiments in heating PWR fuel rods to destruction under near LOCA conditions had, amongst other things, shown that release of I 131 from defective fuel rods is several orders of magnitude smaller than the 3 % of inventory expected in accordance with safety guidelines for the operation of nuclear power stations. In the ISOLDE project these results were broadly confirmed and additional results were obtained through a follow-up investigation, the aim of which was to account for all the iodine released from the fuel rods.
