Theofanous, T G

An overview of core disruptive accidents in LMFBRs and an assessment of their potential for energetic consequences are presented. Areas in which current state-of-the-art is found inadequate are identified. In particular the early post disruptive period (called herein Transition to the Transition Phase) is identified as a key area having received inadequate attention to date. Further the idea of mild dispersal from a fully developed Transition Phase at decay heat power levels does not appear justified. However considerable question exists as to the attainability of such full core pool under accident conditions. Specific recommendations for research work in relation to licensing needs are presented.
