Abstract: | The 18 km long banks of the Bohunice NPP waste water recipient are contaminated by137Cs as a result of two accidents on the CO2 cooled NPP-A1 unit in 1976 and 1977. Contamination acceptance limits 6 or 8 Bq137Cs/g of soil, depending on contaminated area size, were derived on the basis of developed principles, and approved by the authorities. Removing and safe burial of 1100 m3 of contaminated soil from steep area and 15 cm thick clean soil covering on about 1 ha of flat area of the contaminated banks is planned in frame of the re-considered restoration project implementation in 1995/96. |
