7D30/C - Devonport Conditioned Sludge (for Disposal to NWS)
The waste arises from the operation of the radioactive effluent treatment facilities. Particulate material can settle in tanks forming the sludge which is removed. Similar sludges are also removed from portable effluent tanks during periodic maintenance operations.

7D31 - Devonport Filters (for Disposal to NWS)
The waste originates from radioactive effluent treatment. The filters are used to remove radioactive particulates from the liquid during processing. Liquid arises from the refit, repair and maintenance of nuclear powered submarines.

7D34 - Ion Exchange Resin from Primary Circuit Decontamination
The primary circuit of the reactor power plant is decontaminated using a multi-stage chemical process. Resin is used to remove soluble metal activation products that are generated when the magnetite layer is removed from the primary plant.

7D40 - ILW PCD Ion Exchange Resin
The primary circuit of the reactor power plant is decontaminated using a multi-stage chemical process. Resin is used to remove soluble metal activation products that are generated when the magnetite layer is removed from the primary plant.

7D41 - ILW Submarine Ion Exchange Resin
During operation of the submarine reactor system primary coolant is passed through an onboard ion exchange resin which removes soluble activation products and also acts as a very coarse filter.

7F22 - Submarine Reactor Wastes (Non-metallic)
Non-metallic LLW is generated primarily from reactor maintenance; secondary wastes are generated in facilities that provide submarine support services e.g. radioactive component processing, radiochemistry laboratory, etc.
