Plug Valve

Experimental studies have been developed on a new freeze plug concept for safety valves in facilities using molten salt. They are designed to allow the closure of an upstream circuit by solidifying the molten salt in a section of the device and to passively melt in case of a loss of electric power, thus releasing the upper fluid. The working principle of these cold plug designs relies on the control of the heat transfer balance inside the device, which determines whether the salt inside the cold plug solidifies or melts. The device is mainly composed of steel masses that are dimensioned to provide sufficient thermal heat storage to melt the salt and thus open the cold plug after the electric power is stopped. The final goal of the work is to provide useful recommendations and guidelines for the design of a cold plug for the emergency draining system of a molten salt reactor. Some numerical thermal simulations were performed with ANSYS mechanical (Finite Element Method) to be compared with results of the experiments and to make extrapolations for a new component to be used in a reactor.

Electricity Tariff

The article highlights one of the unsolved problems of the Russian power industry management. In most of the works, cross-subsidization in the electric power industry is considered in negative connotations. It is shown that in the design of the electricity tariff with cross-subsidization, along with the negative side, there is also a positive side. The article presents views on the problem of people who are active in decision-making, but pas-sive in the public scientific space.

Abstract Keta District provides one of the best wind regimes in Ghana and farming is the main occupation of most people in the communities of the district, notably the anloga community. A small size wind pump (1.6m rotor diameter) is currently in operation in Anloga in the Keta District on pilot bases to verify its cost effectiveness compared with the hydro electric power technology. The high electricity tariff paid every month for power consumption deterred majority of the farmers using hydro electricity technology for pumping. A survey conducted revealed that out of about 50 farmers, only 29% engaged in the use of electric power for pumping whilst 69% still use the manual method. 2% of the farmers are using wind energy technology on pilot bases. Farmers in these coastal communities may have engaged in the use of wind energy for water pumping but for its high initial cost.
