Waste, radioactive, from nuclear power plants
 scroll 
Raw radioactive waste is produced in nuclear power
plants through cleaning of the cooling circuit, air and water from control
areas and cleaning of the system. Spheroidal resin and filter cartridges
are used to clean the cooling circuit, e.g. in pressurized water reactors.
Evaporation drying systems, centrifuges and ion-exchange filters are
used to clean the waste water. The air is cleaned with filters. Combustible
and compactable waste in particular is produced during cleaning of the
system. The raw waste is either treated directly in the nuclear power
plant or in an external waste conditioning plant. Procedures such as
drying, compacting or burning result in a considerable volume reduction.
The annual volume of radioactive waste produced through the operation
of a 1,300 MWe nuclear power plant with a pressurized water reactor
amounts to:
-
Ion-exchanger resins 2 m3,
-
Evaporator condensate 25 m3,
-
Metal parts, insulating material 60 m3,
-
Paper, textiles, plastics 190 m3.
The annual volume of radioactive waste produced through the operation
of a 1,300 MWe nuclear power plant with a boiling water reactor amounts
to:
-
Ion-exchanger resins 8 m3,
-
Evaporator condensate 35 m3,
-
Filter auxiliaries, sludges 90 m3,
-
Paper, textiles, plastics 300 m3.
