Description of the legal entity

Slovak University of Technology in Bratislava (hereinafter referred to as "STUBA") is an educational and scientific institution. At present, it consists of seven faculties. All the faculties provide a study in accredited study programmes within the complex system of a bachelor, master and PhD. study. Faculties realise credit system compatible with the European credit transfer system enabling mutual mobility of students within European Union member countries and a larger European space. In the area of scientific and research activities the STU successfully joints European Union programmes. STU is a public university and offers education mainly in technical, technological, technical-economical, technical-information and technical-artistic fields of study. International cooperation is a significant area based on interactive contact with educational as well as scientific-research institutions of the countries all over the world. First of all, it is focused on solution of the joint projects within the EU framework and other international programmes, mobility of students, etc.

Institute of Nuclear and Physical Engineering (STUBA-INPE) at Faculty of Electrical Engineering and Information Technology of Slovak University of technology is focusing on research of NPPs long/term operation and nuclear safety. Nuclear material science and applications of spectroscopic methods are traditionally important areas of activities.

STUBA-INPE staff is based on 8 professors in physics, nuclear power engineering and material science. There are approximately 40 employees (scientific or research workers) and 10 PhD students.

This institute is also a base for activity of Slovak Nuclear Society (SNUS) and the Slovak Centre for Operation and Decommissioning of Nuclear Facilities. STUBA-INPE has a long tradition in the NDS investigation of RPV materials by use of Positron Annihilation Spectroscopy, Atomic Force Microscopy as well as TEM or SEM. The partner role to the project: research organization.

The partner contribution to the project: performance of R&D work mainly in field of application of non/destructive methods mentioned above (PAS, AFM, TEM, SEM) on selected specimens. Knowledge management in the area of non-destructive evaluation of reactor pressure vessel steels in form of seminars or summer schools for graduate and PhD students are offered as well.

STUBA will contribute in characterization of actual state of art, mapping and development of the structural changes in selected RPV steels specimens as well as in analyses of possible long term operation conditions of PWR.
