Purpose: The purpose of this work is to describe the spectrometric analysis of gaseous cloudformation over reactor mixed uranium-and-plutonium (UP) fuel (U0.8Pu0.2)O2 samplesheated to a temperature > 2,000 С, and thus forecast and evaluate radiation hazardsthreatening humans who cope with the consequences of any accident at a fission reactorloaded by UP mixed oxide (U0.8Pu0.2)O2, such as a mixture of 80% U and 20% Pu in weight.
Materials and methods: The UP nuclear fuel samples were heated up to a temperature of over2,000 С in a suitable assembly (apparatus) at out-of-pile experiments' implementation, theexperimental in-depth study of metabolism of active materials in living organisms bymeans of artificial irradiation of pigs by plutonium. Spectrometric measurements werecarried out on the different exposed organs and tissues of pigs for the further estimation ofhuman internal exposure by nuclear materials released from the core of a fission reactorfueled with UP mixed oxide.
Results: The main results of the research described are the following: (1) following theresearch on the influence of mixed fuel fission products (radioactive isotopes being formedduring reactor operation as a result of nuclear decay of elements included into the fuelcomposition) on living organisms, the authors determined the quantities of plutoniumdioxide (РuO2) that penetrated into blood and lay in the pulmonary region, liver, skeletonand other tissues; and (2) experiments confirmed that the output speed of plutonium out ofthe basic precipitation locations is very small. On the strength of the experimental evidence,the authors suggest that the biological output of plutonium can be disregarded inthe process of evaluation of the internal irradiation doses.
