7. RADIOACTIVE WASTE (RAW)
Radioactive waste management
Radioactive waste management represents activities, which are focused on their minimising, efficient treatment, conditioning into a waste package and their safe disposal. In compliance with the obligations arising from international agreements, inspection and assessment activities of UJD were focused on activity and volume minimisation of produced radioactive waste and increasing of radioactive waste management process safety.
Radioactive waste generation
Amount of radioactive waste produced at NPPs V-1 and V-2 Bohunice as well as at NPP Mochovce in 2000 is given in table No. 7.1. As a consequence of reconstruction works realised on unit 1 in the frame of nuclear safety improvement, higher solid radioactive waste volume was produced at NPP V-1 Bohunice.
Treatment, storage and conditioning of radioactive waste
Produced liquid and solid radioactive waste is stored within the stores of individual nuclear installations. Volumes of stored radioactive waste are given in table No.7.2. Liquid radioactive waste has been conditioned into the solidified waste form by bituminisation at bituminisation facilities. BSC for the cementation of radioactive concentrates was commissioned at the end of 2000, too. Solid radioactive waste is treated at BSC by supercompaction or incineration, respectively. Volumes of treated and conditioned RAW at SE-VYZ in 2000 are given in Tab. 7.2
Transportation of radioactive waste
In 2000 the need of both on-site and off-site radioactive waste transportation was increased in coherency with NPP A-1 Bohunice decommissioning as well as BSC and repository commissioning. On the basis of consignor applications and according to the “Atomic Act” and competent regulation, UJD approved 5 types of transport equipment and issued 4 permits for radioactive waste transportation. Approval of transport equipment fibre reinforced concrete container and transport permit for waste package in this container to the repository played a significant role. It means that the compatibility of final steps in radioactive waste management process was solved successfully. In frame of decision process, tests should be carried-out with fully changed transport equipment to demonstrate compliance with legal requirements. Total number of performed transports and amounts of transported radioactive waste are given in table No.7.3. Transport of this radioactive waste has been performed by SE-VYZ in co-operation with NPP Bohunice. UJD performed inspections on selected transports of radioactive waste through the routine inspection activities of its site inspector. All transports of radioactive waste were carried-out in accordance with conditions set down by relevant UJD decisions (Table 7.4). In 2000 no events occurred during the radioactive waste transports.
