COVERS Co-ordination Action “Establish a viable RTD structure with a view to enhance the scientific and technical cooperation of actors involved in VVER safety research … (utilities, manufacturers, regulatory bodies, users)”. EU operate VVER units (440 and 1000 MW) Units in operation/construction in Ukraine and Russia Operation of all units was safe and efficient National supporting technical organisations / National R&D
COVERS Co-ordination Action General objectives of CA: • maintain and improve safety • common database - “good practice” • identify/initiate required RD • strengthen links - exchange of information • knowledge management & dissemination platforms • harmonised Safety Culture • cooperation with ISTC (Ukraininan / Russian org.)
