VÚEZ, a.s.

VÚEZ activities in the field of R&D are aimed predominantly at applied research of emergency systems for nuclear power plants (NPP) as well as leak tightness enhancement of NPP hermetic compartments. The following activities are concerned:

• Analysis of used insulation materials, used paints, cables and other materials that can be encountered in the debris distributed in the coolant after an accident
• Monitoring the interaction of debris and coolant under real post-accident conditions, the impact of the debris on efficiency and functionality of filtering elements
• Manufacture of experimental facilities, instrumentation, and control, manufacture of prototype filters, the performance of qualification tests, evaluation of results
• Implementation of test results in new designs of plant-specific strainer structures
• Tests of materials under radiation load. Injection polyurethane materials and sealants based on EPDM synthetic rubber
• Modification, design, and testing of shaped double seals for local leak tests of airlocks
• Monitoring of hermetic liner
