MONITORING OF THE RELEASE OF ~(238)Pu, ~(239,240)Pu, ~(241)Am, ~(242)Cm, and ~(244)Cm IN THE AIRBORNE EFFLUENTS FROM CZECH AND SLOVAK NUCLEAR POWER PLANTS

摘要

The concentrations of ~(238)Pu, ~(239,240)Pu, ~(241)Am, ~(242)Cm, and ~(244)Cm in airborne effluents and the discharge of radionuclides was determined at the V1 and V2 nuclear power plants at Jaslovske Bohunice in the Slovak Republic and the V3 and V4 nuclear power plants at Dukovany in the Czech Republic in 1991, 1992, and 1993. The concentrations of isotopes of transuranium elements and the discharged radionuclides at the V1 nuclear power plant were significantly higher than those at V2 and especially at V3 and V4. For example in 1993, the concentrations of ~(239,240)Pu in airborne effluents of nuclear power plant V1 were kept in the range of 3.0-26.0 μBq.m~(-3), whereas at V2, V3, and V4, they were in the range of < 0.04-0.11, < 0.01-0.10 and of 0.01-0.05 μBq.m~(-3), respectively. Temporal variation of discharge data, ratios of transuranium radionuclides in airborne effluents, and related topics are discussed.
