Current and future LWR severe accident related R and D activities at KfK

A broad spectrum of safety investigations into LWR design basis and core meltdown accidents had been covered by the Nuclear Safety Project (PNS) during the past decade. Since the beginning of 1987, LWR safety research and development (R+D) activities conducted at KfK have been reorganized and are now being coordinated by the LWR Safety Project Group (PRS). The topics further treated under PRS relate mainly to severe accident analysis research, measures of source term mitigation and accident consequence limitation. In a more general sense, these activities should be seen within the framework of probabilistic risk assessment studies being performed in Western Germany and scheduled for the future, respectively. This contribution is a summary of some recent findings, of the present status, and of future prospects of LWR oriented R+D work at KfK
