Waste Management Division

Waste from NPP

Radioactive waste generated from NPP can be divided into

–power reactor wastes, and– fuel cycle facility wastes,

•Power reactors are responsible for the largest volume of LLW. •Fuel cycle plants, such as fuel enrichment plants and fuel fabrication plants, produce small volumes of LLW relative to power reactors.

Power Reactor Wastes

The majority of power reactor wastes : 1) Liquid radioactive wastes,2) Wet solids (including slurries),3) Dry active solid wastes (DAW), 4) Liquid organic wastes, and5) Thermal waste.

Power Reactor Wastes

Power Reactor Wastes1) Liquid Radioactive Wastes• Liquid radioactive wastes are produced from

recycled reactor core fluids, hydraulic fluid from equipment repairs, housekeeping activities, and laundering.

• These wastes are treated to remove the maximum amount of radioactive contamination.

• Treated liquids are then typically recycled or discharged to the environment under the control of the plant operating license and national regulations.

2) Wet solids Radioactive wet solid wastes consist of solid wastes

containing greater than 5% liquid. Most radioactive wet solid wastes are produced from cleaning aqueous processing systems at power reactors.

• Spent Ion-Exchange Resins• Filter Sludge• Cartridge Filters

Power Reactor Wastes

Power Reactor Wastes3) Dry active solid

wastes• Cloth (rags, mops, gloves)• Contaminated dirt• Contaminated tools and

equipment, Filters• Glass• High density concrete block• Miscellaneous metal, Aerosol

cans, Buckets, Crushed drums, Fittings, Pipes and Valves

• Miscellaneous wood• Plastic• Bags, gloves, shoe covers,

Sample bottles• Rubber, • Sweeping Compounds• Irradiated metal alloys• Flux wires, Flow channels,

Fuel channels, In-core instrumentation, Poison channels, Shim rods.

Power Reactor Wastes4) Liquid organic wastes• liquid organic wastes includes pump oil,

lubricating oils, organic resins, liquid scintillation counting solutions, and decontamination solutions containing organic chelating agents.

• Liquid organic waste volumes are very small when compared to the total generated volume of LLW

Power Reactor Wastes5) Thermal waste• This waste is common both to conventional and

nuclear plants.• The quantity of thermal waste proportional to the

size of the plant.• In a NPP with a PWR operates at a thermal power of

1000 MW must dispose of approximately 2.4 million Btu/s. If this quantity of heat were released into a river having a flow rate of 1000 cubic ft/s, the entire river temperature would rise by 33 degrees Fahrenheit.

Fuel Cycle Wastes

Fuel cycle facility wastes include • Calcium fluoride generated from hydrogen

fluoride gas scrubbers,• Filter sludge, • Contaminated equipment, and• Trash.
