Concrete Waste Recycling and Re-use of Shielding Wall Materials After Decommissioning of Fusion Reactors

The paper considers possible processing and re-use of waste products obtained in the process of removal from service of pre-fabricated concrete structural elements of biological protection shields at thermonuclear fusion reactors. The experimental concrete compositions have been obtained through the mechanical-and-chemical processing of crushed concrete structures which had worked under neutron radiation with the energy of 14.8 MeV. These concrete compositions have been studied, and some ways of total or partial substitution of the Portland cement by crushed small-grain waste products in the process of erection of concrete or reinforced concrete structures are considered as well.

Outlooks for Building Solar Charging Infrastructure for Self-propelled Electric Vehicles

The article examines key issues and outlooks for use of recharging photovoltaic stations (PVS) by recharging infrastructure for electric self-propelled vehicles, to be created in Russia. Methodical justification of the use of charging PVS are presented according to the studies of different options for the development of power supply to consumers which are isolated from power systems, including consumers from the remote regions of the Russian Federation. It offers a methodology to design pilot algorithms to validate use of PVS in the electric vehicle recharging infrastructure to be created in some Russian regions; it is used as basis to analyze the potential of different regions for PVS implementation in the electric vehicle recharging infrastructure.
