The Băiţa Bihor (DNDR) repository was sized for storing approx. 5000 m³ of conditioned radioactive waste. Storage of the first packages with radioactive waste started in 1985 and is to be used further by the year 2040. The repository is set up in the galleries of a disused uranium mine  in the mountains of Bihor, which is part of the Western Carpathians.

The area is mountainous and relatively isolated, the nearest settlement being a small mining village called Băiţa Plai, located 2 km west of the deposit. The deposit is intended for accommodating radioactive waste originating outside the cycle of nuclear fuel, respectively radioactive waste arising from industrial activities, medicine and research.

Activities the Consortium has to perform for the DNDR improvement of safety project are presented succinctly in the scheme below.

According to the conception of the project, CITON is to identify necessary measures to improve isolation technology of radioactive waste packages from DNDR and to transmit theme data for research in order to establish a improved option for filling the gaps in the galleries. These theme data shall be transmitted in the framework of the activities 1.1. A and 1.1.B. The results of these investigations will be sent to CITON within activities 1.2 and 1.3. Based on these results CITON will perform an assessment analysis on the effectiveness of the proposed solutions and will determine measures for detailing the optimal option. As a result of this analysis, it will move to the continuation of research in directions agreed in an interactive process with the participation of partners. The results of this research turning into an innovative technology will be sent to CITON for performance assessment. The data obtained will form the basis of the closure plan in terms of nuclear safety of the DNDR, plan which will be prepared by CITON.
