The problem of long-lived radionuclides is discussed for three liquid-metal coolants: Na, Pb−Bi, and Pb. Their irradiation in the high-energy neutron spectrum of a fast power reactor for 50 yr is examined. It is found that the radiation properties of the coolants differ substantially, which could be decisive for handling them as radioactive wastes. It is concluded that sodium is closest to a radiationally waste-free technology. 2 figures. 5 references. 
Investigating on Radioactivity of LBE and Pb in ADS Spallation Target
Using the Fluka Monte Carlo method, we argue the activity of lead-bismuth eutectic (LBE) and lead (Pb) spallation targets in Accelerator Driven Subcritical System (ADS). Results reveal that the
The effect of Prandtl number on turbulent sheared thermal convection
Abstract In turbulent wall sheared thermal convection, there are three different flow regimes, depending on the relative relevance of thermal forcing and wall shear. In this paper, we report the

Residual radioactivity of materials from decommissioning of fast reactors
This article examines the residual reactivity of materials from the decommissioning of fast reactors in Russian Federation states. The BN-800 reactor decommissioning is used as the basis of this
