Nuclear power source

Pu (86 years) is formed from Np. Pu is separated by selective oxidation and solvent extraction. The metal is formed by reduction of PuF with calcium there are six crystal forms. Pu is used in nuclear weapons and reactors Pu is used as a nuclear power source (e.g. in space exploration). The ionizing radiation of plutonium can be a health hazard if the material is inhaled. 

The isotope plutonium-238 [13981 -16-3] Pu, is of technical importance because of the high heat that accompanies its radioactive decay. This isotope has been and is being used as fuel in small terrestrial and space nuclear-powered sources (3,4). Tu-based radioisotope thermal generator systems dehvered 7 W/kg and cost 120,000/W in 1991 (3). For some time, %Pu was considered to be the most promising power source for the radioisotope-powered artificial heart and for cardiovascular pacemakers. Usage of plutonium was discontinued, however, after it was determined that adequate elimination of penetrating radiation was uncertain (5) (see PROSTHETIC AND BIOMEDICAL devices).

The properties of self-protecting the RIs using LBC allow to create ecologically pure nuclear power sources of enhanced safety. 

Many developing countries in Africa an Asia suffer from deficiency of fresh water and electric energy. The majority of these countries do not have sufficient own resources of fossil fuel, which can meet their demands. In some countries fuel transporting is difficult, there are no powerful electric power transmission lines. The marketing researches conducted recently by IAEA [26] have revealed that in many cases nuclear power sources of 100 MWe small power can be used economically effective for these purposes.
