Concrete with high resistance against chemical attack and against freezing. The application in cooling towers, tanks and chimneys. 2. Development of ultra high performance concrete with extreme mechanical properties (strength>150 MPa) and excellent resistance against environment. Verification on a trial structure. 3. Technology of construction of very thick elements (e.g. foundation slabs) requires special materials and erction processes. 4. The technology of dynamically loaded foundations under turbines will be developed, to avoid cracking and eigenstresses and possible repairs. 5. Investigation of the impact loading to outer reactor vessels. Methods of monitoring and system of safety evaluation during service life. 6. Investigation of composite steel-concrete inner reactor vessel exposed to high temperature and presssure. Methods of monitoring, reliability evaluation."@en . . " service life" . "63"^^ .
