EPR UK N° NESH-G/2008/en/0123 REV. A PAGE 46 / 257 6.3.7 Air and Water Filters TABLE 9: WASTE STREAM DATASHEET FOR AIR AND WATER FILTERS Waste Steam Air and Water Filters Waste Origin All radiation controlled areas of the nuclear auxiliary building, fuel building, safeguards buildings, reactor building, operational production centre, access building and waste treatment building are served by dedicated ventilation systems. The extract from these systems is subject to a number of airborne activity abatement techniques, including the use of HEPA filtration, before discharge to the environment. The abatement systems will therefore produce a number of spent HEPA filters over the course of reactor operations. These HEPA filters have the potential to be classed as radioactive waste should they have arrested any radioactive particulate or aerosol. In addition, water filters may arise from filtering of the low active effluent filtration (Gaseous Treatment System, Liquid Waste Treatment System, Steam Generator Blowdown System) Waste Physical Description Cartridges are composed principally of stainless style supports with glass fibre filter and some organic materials. The amount of particulate radioactive material (metallic oxides) trapped on each filter may be variable. Nature of Radioactive Material Particulate (metal oxide) contamination up to a few Bq/g. Annual Arising 4 m 3 Total Arising 240 m 3 Waste Classification at Time of Generation LLW Main Radionuclides Cobalt-58 Iron-55 Cobalt-60 Silver-110m Manganese-54 Hazardous Substances Boron: 8150 ppm Lead: 904 ppm Chromium: 333 ppm Nickel: 291 ppm Arsenic, antimony, mercury: 7 ppm Beryllium: 0.3 ppm Selenium: 3 ppm Cadmium: 15 ppm
EPR UK N° NESH-G/2008/en/0123 REV. A PAGE 47 / 257 6.3.8 Oils TABLE 10: WASTE STREAM DATAHEET FOR OILS Waste Steam Oils Waste Origin Oils are used in the lubrication of process pumps. Oils arising from circulators and pumps used to transfer radioactive liquids have the potential to become contaminated. Waste Physical Description Lubricating oil from various circulation pumps. Nature of Radioactive Material Lubricating oils have the potential to become slightly contaminated during service. Annual Arising 2 m 3 Total Arising 120 m 3 Waste Classification at Time of Generation LLW Main Radionuclides Cobalt-58 Iron-55 Cobalt-60 Silver-110m Manganese-54 Hazardous Substances Waste oil is considered to be a hazardous substance.
