Although gaseous fraction of iodine is expected to be small in quantity compared with its other forms such as CsI, because of its radiological consequence, removal of elemental iodine vapor from the gas bubbles in water pools defines an important boundary condition for the severe-accident scenarios that involve water pools. The Muehleberg nuclear power plant (a boiling water reactor Mark 1 type) in Switzerland has a unique feature, namely, a second suppression pool surrounding the reactor building in addition to the regular pressure suppression pool. For those hypothetical accident scenarios that involve the second pool, scrubbing in the second suppression pool would ultimately determine the magnitude and constitution of the release. An experimental program, pool scrubbing effect on iodine decontamination (POSEIDON), was initiated at Paul Scherrer Institute (PSI) in Switzerland in 1987 to provide a data base on gaseous iodine scrubbing. Bubbles containing elemental iodine vapor and nitrogen as the carrier gas are generated using certain sized orifices immersed in a water pool. Objectives of the experimental program are defined as (a) to understand the iodine removal phenomena from bubbles and (b) to provide a data base for iodine retention under controlled boundary conditions for the development and verification of the BUSCA-PSI pool scrubbing code.
