Kazachkovskii] Conclusions: At present, the thermal reactors have the economic advantage. The gain in the fuel component of fast reactors, it must still be acknowledged, still cannot compensate the loss in the specific capital investments, because the contribution of the fuel component to the cost of electricity is now small. However, in the future, as the uranium produced becomes more expensive, the situation should change in favor of fast reactors. It is difficult to predict when such an economic inversion will occur, because, as we have pointed out, the real, experimentally confirmed, data on the costs of serially produced fast reactors as well as the cost of the external fuel cycle, optimized for these reactors, are not available. There are no reliable predictions of the increase in expenditures on uranium production. At the same time, the technical problems of fast reactors will require a long period of time to work out in scale, at least because of the need for guarantee reliable assimilation of the sodium coolant on industrial scales and also because deep burnup of fuel must be ensured. Experience in developing and operating commercial BN-350 and −600 reactors has been positive. The construction of small, serially produced, fast reactors should continue, even if they will formally remain economically less advantageous, for some time, than the already well-assimilated serially-produced thermal reactors. The main problem here will be to improve the technology of both the reactors themselves and the external fuel cycle. In this respect the prospects are good in both cases. At the same time, allowance must be made for the fact that the inversion of the economic advantage will probably occur even before the end of the service life of the currently designed, serially-produced, first-generation fast reactors. Then these reactors will be more advantageous.
