Abstract
The article considers the possibility of producing plutonium suitable for radioisotope thermoelectric generators (RTG) of space vehicles, using the americium fraction of minor actinides (MA) as a starting material. It was supposed to place such a starting material in the central fuel assembly of the VVER-1000 light water reactor and the lead-cooled fast reactor BREST-1200. The preference for using only the Am-fraction of MA instead of the Np-fraction and the mixed Np−Am-fraction of MA is shown. The main advantage of the Am fraction is the fundamental impossibility of the appearance of undesirable 236Pu with hard γ-radiation of its decay products. A comparison of the conditions for the production of plutonium suitable for RTGs in the VVER-1000 and BREST-1200 reactors indicates a higher rate of production of such plutonium in the BREST-1200 fast reactor.
