SAFETY AND ECOLOGY
Safe operation of nuclear facility during all lifetime is the important task for any organization which has been working at the area of nuclear energy application, especially in country, been affected by Chernobyl accident. Nuclear and radiation safety related issues always draw the attention of people.
Ukraine is one of the first countries, who took part in Convention of nuclear and radiation safety in 1994 and in Convention for safe handling with radioactive waste and safe handling with spent fuel. During the Independent years, the significant scope of works directed to increasing of nuclear and radiation safety was made. Priority of nuclear facilities safety assigned to the Law of Ukraine “Usage of nuclear energy and radiation safety”.
State Committee of Nuclear Regulation, Ministry for Health Protection, Ministry for Emergency Situation, Security Service, State Department for Fire Protection, State Committee for Labor Protection, Ministry for Environmental Protection, as well as Public Organizations and IAEA supervised NPP operation and activities.
The estimation of radiation safety status is determined by quantity characteristics, which are as follows: scope of radioactive materials emission into atmosphere, discharge them into water reservoirs, scope of radioactive wastes produced, average, maximum and summary indexes of levels of external and internal exposure of plant personnel and population of territories adjacent to KhNPP.
Radioactive wastes are regulated by document “Admissible gas-aerosol emission and water discharge of radioactive materials of KhNPP” developed by Scientific and Research Institute of radiation protection and approved by Health Protection Ministry of Ukraine.
The complex of organizational and technical measures provided personnel safety and excluded NPP impact on environment and local population was implemented at KhNPP:
1. equipment of primary circuit is located in containment.
2. gas-aerosol emission and liquid releases are purified in special treatment systems.
3. radioactive wastes are transported into special nuclear waste storages.
4. all technological systems and rooms in which radioactive materials may be appeared, are controlled by radiation sensors, the information from which displays on main radiation control broad.
5. Continuous radiation monitoring of the territory around KhNPP is performed.
Due to implemented measures during KhNPP operation the excess of preset limit of personnel exposure, cases of occupational deceases, induced by exposure have not been fixed and actual gas-aerosol releases into atmosphere have not exceed 0,1 % of preset admissible values. According to monitoring results the content of radioactive materials in environmental objects practically coincides with “null background” values, fixed before KhNPP operation, in other words KhNPP impact on population is absent.
Khmelnitsky NPP implements systematically activities for prevention of accidents and modernization of emergency preparedness system in case of contingencies and accidents. Plans for emergency response at site and adjacent territories are developed and keep updated.
Operation manuals are approved, they defined actions of operating personnel in emergency situations. Emergency training are conducted for the KhNPP personnel training.
Ukraine is the participant of “Convention on assistance after nuclear accident or radiation accident”. Bilateral agreements regarding announcement about nuclear accidents and mutual aid in such accidents were assigned with governments of Austria, Hungary, Germany, Norway, Poland, Slovakia, Sweden, Finland.
