- Stainless Steel (Reactor) LLW
Stainless steel items from reactor dismantling.
Nuclear Restoration Services Ltd (NRS) | Bradwell | LLW
9B321
- Contaminated Soil LLW
Contaminated soil that has resulted from plant operation and maintenance.
Nuclear Restoration Services Ltd (NRS) | Bradwell | LLW
9B323
- Thermal Insulation (Asbestos) LLW
Insulation materials from active plant dismantling. Construction drawings identify that both the RPV and primary circuit components were insulated with non-asbestos material (Rocksil and Centritex) which is presumed to be cross contaminated with asbestos based upon present evidence. The volumes of insulating materials were Reactor Pressure Vessel 160m3, Top ducts 32m3, Bottom ducts 22m3 and Bottom branch 8m3.

9B55/C
- Ponds Decontamination Sludge
Sludge from ultra high pressure washing of the pond walls and skips and sludge accumulated at the base of the pond during operations. Sand originated from the Pond Water Treatment Plant (PWTP).

9B59/C
- FED Magnox
The source of the waste is the removal of splitters from fuel elements prior to dispatch of the elements for reprocessing. This waste was processed through the FED dissolution plant.

9B79/C
- FED Magnox - Solid Secondary Waste
Consists of segregated items, isolated prior to processing of FED through the FED dissolution plant, and insoluble items obtained after processing through the FED dissolution plant.

9B81/C
- FED Magnox - Secondary Ion Exchange Resin (Co-Treat)
The secondary Ion exchange resin originates in the ADAP from the abatement of FED dissolution discharges. The ADAP plant used Co-Treat and Cs-Treat proprietary Ion Exchange (IX) resins to remove soluble radioactive components from the effluent, minimising the activity discharged to the environment. This waste stream refers to the Co-Treat.

9B82/C
- FED Magnox Dissolution Secondary Waste (Sludge)
The sludge and ion exchange material originate from the abatement of the dissolution plant discharges. During the abatement process, constituents that are insoluble in acid will be containerised in sludge tank(s).

9B83/C
- Graphite Filter Dust Pots
The waste was produced in the by-pass filters, located on the reactor gas circuits. The graphite dust (and rust fragments) in the gas circuit were deposited into the by-pass filter catch pots, which were in-turn decanted into plastic bags within the interim storage filter dust pots, which were constructed from 8 inch nominal bore carbon steel pipe fittings. Sand arose from filter units in the Pond Water Treatment Plant (PWTP) - formerly known as 9B65.

9B84/C
- FED Magnox - Secondary Granular Activated Carbon (GAC)
The secondary Granulated Activated Carbon (GAC) originates from the abatement of FED-dissolution plant discharges.
