Late phase source term phenomena

Obiettivo

A programme is proposed to quantify fission product and core materials released from molten corium. This work will examine the kinetics of release of the key fission products (as simulants), and also allow the importance of key phenomena (e.g. sparging, slag formation, two-phase systems) to be determined. There will be a series of experiments to aid with understanding the chemistry of species released during the late phase of an accident, together with experiments aimed at examining the long-term behaviour of a solidified core immersed in a water pool.

The results will be used to develop generic code models for the relevant phenomena. The models and experimental results will be used in plant calculations for Eastern, Western and advanced designs. The programme will aid in the development of accident management strategies and provide data on fission product behaviour in the late phase of an accident.
