• Containment spray tests for elemental iodine vapor removal were conducted under simulated BWR LOCA condition with large-scale JAERI Model Containment. The tests were carried out to determine the behavior of gas phase iodine removal by spray water containing carbonic acid, the mixing effect in the sump pool, and iodine deposition onto the containment wall.<BR>In the tests, a half-life of the iodine concentration decrease in gas phase was obtained as 6-12 min and an iodine partition coefficient was also obtained as 80160 by the spray washout under pH range of 5.35.9. The effect on the mitigation of pH decrease of spray water caused by the iron corrosion process was discussed from the experiments. Results obtained from the tests were compared with those calculated by a code MIRA-PB.
