NEA Behaviour of Iodine Project Phase 3 (BIP-3)

The Behaviour of Iodine Project Phase 3 (BIP-3) is a follow-up to the BIP Phase 2 (BIP-2) and BIP Projects that provided results from separate effects and modelling studies of iodine behaviour in a nuclear reactor containment building following a severe accident. While painted surfaces are a very important iodine sink within containment, they represent a pathway that converts molecular iodine into organic iodine which is less easily trapped than molecular iodine by conventional iodine filtration methods (charcoal, wet scrubbers). Building on the earlier experiments performed by CNL (Canada), BIP-3 is attempting to answer some of the outstanding questions raised during BIP and BIP-2 where the specific technical objectives are:

It should be noted that the BIP and STEM projects have strong scientific links with complementary objectives and many common partners.
