This type of mining is particularly damaging to the environment because strategic minerals are often only available in small concentrations, which increases the amount of ore needed to be mined. Environmental hazards are present during every step of the openpit mining process. Hardrock mining exposes rock that has lain unexposed for geological eras. When crushed, these rocks expose ...
In certain types of nuclear power plants, however, the use of high temperature steam must be avoided, as it would cause problems with the material used in the turbine equipment. Instead, high pressure saturated steam is typically used. Where saturated steam must be used, separators are often installed in the supply piping to remove entrained condensate from the steam flow.
nuclear reactor nuclear reactor Types of reactors: Most of the world's existing reactors are power reactors, providing the heat needed to turn turbines that run electricpower generators. There are also numerous research reactors, and some navies of the world have submarines or surface ships driven by propulsion reactors.
