Radiation Protection

Radiation protection in nuclear power plants refers to procedures for radiation protection and prevention of contamination. Radiation protection also ensures occupational radiation exposure monitoring, the prevention of the proliferation of radiation sources and measurements in the workplace, measurements of radiation levels in the air and in effluents as well as measurements near the plant.

Chemistry Program

Chemical parameters of the Krško NPP cooling systems are regulated through the chemistry program for ensuring the long-term integrity of equipment and systems, such as the primary coolant circuit, steam generators, nuclear fuel etc. as well as dose limits for occupational exposure. An effective chemistry program is based on chemical and radiochemical analyses.
