Monitoring of radionuclides in waste water of Temelin nuclear power plant

The Vltava river is the source of water for the power plant and the recipient of its waste water. The sewerage system of the power plant is described, divided into 5 independent parts by the source of the discharge. The discharge of water with maximal permitted content of radionuclides would increase the dose rate in the river by less than 3% which is less than the fluctuation of the background. The question is discussed of tritium in waste waters as are possible pathways of its escape into the environment. Tritium-containing water from the primary circuit will be discharged into spray pools. The table shows project specific activities of important radionuclides in technological waste waters and the respective dose rates in the water from gamma radiation (M.D.). 1 tab., 5 refs
