OECD/NEA Behaviour of Iodine Project, Phase 2 (BIP-2)

The Behaviour of Iodine Project, Phase 2 (BIP-2) is a follow-up to the BIP Project that has provided results from separate effects and modelling studies of iodine behaviour in a nuclear reactor containment building following a severe accident.

AECL's Chalk River Laboratories in Canada is the primary research facility for the project. Key facilities include Co-60 irradiators (Gammacells), active laboratories for performing I-131 tracer studies, specialised surface science laboratories (capable of working on active or inactive samples) and extensive hot cell facilities. With these facilities, and within the framework of the BIP Project, the group has successfully performed more than 50 tests dealing with the adsorption of iodine on surfaces and the formation of organic iodides from irradiated paint.

This new joint project will complement other national and international experimental programmes such as SARNET2 which are also studying this phenomenon. Project participants will seek to combine international resources to produce a consolidated understanding of the behaviour of iodine and other fission products in this scenario. The specific technical objectives for this follow-up project are:

It is expected that an extensive analytical effort will accompany the experimental programme, mainly consisting of data interpretation, result evaluations and modelling for application to reactor situations.

Project participants

The project is being supported by safety organisations, research laboratories and industry in the following countries: Belgium, Canada, Finland, France, Germany, Japan, Korea (since 2013), Spain, Sweden, the United Kingdom and the United States.
