The need for fast reactors in nuclear power is discussed. The advantages of fast helium reactors over fast liquid-metal reactors are shown. Fast helium reactor concepts and the possibilities of improving breeding by using fuel of higher density than oxide fuel, specifically, carbides and...
The total amount of stored energy (Wigner energy) and the physical-mechanical properties of the graphite plunger, which exhausted its total service life (6 yr), in the No. 2 unit of the Kursk nuclear power plant were estimated experimentally. The results showed that the total accumulated energy...
The experience gained over many years of operating nuclear-powered ice breakers in conquering the northern sea route is described. The conditions which must be met for year-round navigation of cargo ships in the Arctic are presented. For such navigation to be realistic, it must be profitable and...
At the final stage of the existence of nuclear power, when power reactors stop operating and the previously accumulated acitindes have been transmuted, it is necessary to transmute the actinides which were accumulated in the transmutation reactors themselves without makeup by new actinides....
A method for assessing the damage to water resources as a result of discharges of radioactive substances into an open water reservoir is described for the production operations of the Moscow Scientific-Industrial Association Radon. The actual damage and the potential damage due to discharge of...
The main objective of this work is to study experimentally the range and number distribution of 235 U fission fragments over the thickness of thin lavsan films. A BR-10 reactor was used to irradiate a stack of lavsan films and the first experimental determination of the differential distribution...
A method is proposed for determining the background levels of the radiation parameters of soil: exposure dose rate of the sample and the count rate in β radiometry of a thick-layered preparation. Comparing an actually detected radiation parameter of a soil sample and the background level of the...
The possibility of using activation γ-spectrometry to determine the mass content of nuclear materials in matter is investigated. Irradiation of samples for a short time with moderated neutrons from a ~10 7 sec –1 Pu–Be source is used to induce 1436 keV γ-ray emission from 138 Cs. These...
