This means that some radioactive material gets into the turbine and condensers and pumps , but these are usually very short-lived radionuclides .
这意味着一些放射性物质进入了涡轮和冷凝器还有泵，但是这些进去的大多都是短期的放射性核素。
A ge spokesman said ge opted for the active backup-cooling system in fukushima daiichi units 2 to 6 , and in other reactors , because it believed the system was safer than earlier condensers and was better suited to bigger reactors .
According to sugama , the coating should be of specific interest to industries that produce coated valves , pumps , and other components , as well as the manufacturers of aluminum fins used in air-cooled condensers at geothermal power plants , where preventing brine-induced corrosion is a high priority .
