NATIONAL RADIOACTIVE WASTE REPOSITORY Mochovce
National radioactive waste repository Mochovce is determined for disposal of conditioned low and intermediate radioactive waste. UJD issued a resolution on approval for commissioning of this nuclear facility in October 1999. After completing modifications required by UJD and focused on improving the monitoring system of possible leakage of radionuclides and protection against penetration of rain waters, and after complementing and modification of safety documentation.
UJD in co-operation with other experts from SR and CR approved and reviewed the safety documentation submitted according to §15 of the Atomic Act. The main attention was paid to safety analyses, sensitivity analyses, and uncertainty analyses for the important parameters affecting the processes of radio-nuclides release and repository stability.
Routine inspection activity of UJD (15 routine inspections in 1999) was concentrated on regular control of quality of works related to completion of the National radioactive waste repository. The aim of the team inspection was a complex verification of readiness of the National radioactive waste repository for the commissioning. The measures imposed related mainly to completing the monitoring system for underground water flow and for use of the bar code during receiving and disposal of containers with radwaste.
VUJE BITUMINISATION FACILITY AND VUJE INCINERATOR
There are two nuclear facilities installed at NPP A 1 Bohunice, operated by VUJE with a cementing equipment and a bituminisation facility. The , a. s. : an experimental incinerator bituminisation facility was out of operation in 1999. The incinerator treated the burnable waste from NPP V-1 Bohunice from NPP V-2 Bohunice was verified on the cementing equipment.
Inspection activity of UJD was focused on readiness of the incinerator for operation after an extensive maintenance, on fire risks in conditioning radioactive waste by bituminisation decreasing the fire risk in bituminisation and improvement . Measures imposed by UJD related to of the data recording.
STATISTICAL DATA ON ASSESSMENT AND INSPECTION ACTIVITY OF UJD
Assessment and inspection activities of UJD in 1999, which were completed by issuing UJD decisions are presented in Table 7. The table contains the number of decisions broken down to the major regulated entities, or regulatory activities (transport of nuclear materials, etc.) , issued by UJD in 1999 compared to the previous years of UJD operation. The table illustrates that also in 1999 the dominating activities of UJD focused on NPP V-1 Bohunice and commissioning of Unit 2 of NPP Mochovce.
Overview of inspections performed in 1999 broken down by operating organizations is given in Table 8. Table 9 contains an overview of routine inspections performed by site inspectors in 1999 according to individual nuclear installations.
