Examination of the phosphorus recovery method from turbine control oil.

When an EHC turbine oil used in a nuclear power plant was burned in a furnace, a phosphorus-containing compound with a low-melting temperature formed to clog a ceramic filter for removing an effluent gas. In the present work the compound in the oil was converted into chemically stable phosphates via reaction with calcium hydrate at room temperature. The resulting calcium phosphates could be removed as a fly ash after heating at high temperature. ...

Study on the treatment of EHC-used oil

Boiling water type nuclear power plant(BWR) conducts overhaul of the condenser and the turbine regularly. The radioactive iodine dissipation in the tu rbine system, that occurs in the reactor during plant operation, because it may be released in the atmosphere, implement safeguards against radioactive iodine. Carbon particle filter type local air blower is conventionally used in order to eliminate the radioactive iodine before during maintenance, but has the problem in mobility due to size of the device. ...
