To be able to assess a course and consequences of incidents and accidents at nuclear facilities important from the point of view of their possible impact to the environment, to prepare proposals of provisions or recommendations for further actions as well as for realisation of exercises UJD has built an Emergency Response Centre (ERC). Its creation was preceded by international recommendations and thanks to financial support and expert assistance of Government of Great Britain and Northern Ireland the RRC could have been accomplished and open in April 1995.
ERC basic operation modes
Basic operation modes of ERC are defined in three basic levels:
- Monitoring level
- Emergency level
- Post-emergency level
Monitoring level is basic ERC operation module. It is focussed on monitoring of basic set of technological data and radiological situation on site of nuclear installations, on verification of functionality of equipment, on emergency information system of ERC and on communication means.
At this level ERC prepares current reviews concerning NPP status, which contain a short characteristic of operation and radiation situation.
ERC switch over to the emergency level based on classification of event by the holder of licence for NPP operation or based on changes of monitored technological and radiation parameters. Transfer is characterized by verification of emergency declaration, activation of determined UJD staff members and consequent analysis and evaluation of current status of impacted facility. Monitoring, analysis and assessment of status of impacted facility and radiological situation including forecast of further accident development are basic tasks of ERC during the emergency level mode. An Emergency Headquarters of UJD (EHQ) has been established to assure ERC tasks on this level. EHQ is divided to four groups.
After settlement of emergency situation ERC proceed to post-emergency level and then resumes to the basic monitoring level. This level is characterised by preparation of final protocols concerning course, solution and consequences of the nuclear installation accident and also results of investigation of accident causes are fixed and assured. After fulfilment of all tasks linked to the supervision upon solution of emergency at nuclear facility the ERC activities resume to the monitoring mode level
Timeliness of data for ERC
Transfer of data from NPP V-1 and V-2 in Jaslovske Bohunice is under operation since the end of 1998, from NPP Mochovce since 2000. Approximately 130 parameters from each unit and 700 parameters from radiation monitoring network in NPP surroundings is transferred and updated each 5 minutes and these data are stored in the central data base of UJD. Since 2000 also central climatology data base has been put into operation and data are transferred from Slovak Hydrometeorological institute (SHMU) to this data base in intervals of 10 minutes.
