While the terms waste reduction are more expansive than source reduction in certain ways, they are more restrictive in the sense that while source reduction can be employed in the context of gaseous, liquid, or solid wastes, the term waste reduction is generally used to refer to solid and liquid waste management activities. ...

The radioactive waste management system of the QP300 consists of gaseous waste treatment system, liquid waste treatment system, solid waste treatment and storage system and radioactive waste solidification system. 

For a few decades, Kr-85 artificial production shows a continuous increase of its average volumic activity into the atmosphere. In the North hemisphere, the atmospheric concentration was of 0.1 Bq m" in 1959, 0.8 Bq m" in 1980, and 1.2 Bq m in 2001 (Berard et al., 2001). One cannot say that the removal of tritium and krypton from gaseous waste is an immediate waste management requirement, but it may become one in the future (Lennemann et al., 1975). Opinions differ as to the need to isolate Kr-85. Thus, Geary (1988) states that dispersal is almost certainly preferable to disposal, based on the relatively low inventories and hazards involved. Mellinger (1985) suggested that the population risks arising from the routine release of Kr-85 would not exceed the occupational risk associated... 

So far as the Scope was concerned, some aspects were resolved at least for a preliminary draft, but not without considerable discussion. For example, it was agreed that the Convention should cover all materials whether liquid, gaseous or solid form, and that it should apply to the safety of wastes deliberately released to the environment as discharges as well as those disposed of into repositories. The scope would also cover all activities in the definition of radioactive waste management, namely handling, pretreatment, treatment, conditioning, storage and disposal. 

Intermediate Eevel Waste (ILWL which will comprise mainly adsorption and filter media from gaseous and liquid radwaste treatment. Following appropriate pre-treatment, the ILW will be encapsulated in cement (to immobilise radionuclides) and stored on site (prior to future consignment to an off-site repository facility). A BAT assessment for management of ILW is presented in a Radioactive Waste Management Case Evidenee Report (Reference 14.21). All lEW solid waste streams will be handled in internal areas and not exposed to the external environment. 

In the event that a LOCA were to occur, the released liquids/gaseous should be retained within the containment and building stmcture of the nuclear island, and would subsequently be collected and consigned into the relevant radioactive waste management stream. 

Despite these limitations both methods represent the best techniques currently available and a marked improvement in the knowledge of the tritium inventory of this highly tritiated waste stream when compared to historical Chapelcross paper records which are now superseded. Previous work to determine the specific activity utilised the application of a highly conservative activity conversion factor from liberated gaseous tritium in equilibrium with a solid matrix inside a sealed container to an in-situ P measmement of gaseous tritium. Consequently the maximum specific activity has been determined to be < 25 % of the previous assessment and provides sufficient surety of true activity to support the appropriate onward waste management routing decision for this unique waste stream. 

A chemical waste is any solid, liquid, or gaseous waste material that if improperly managed or disposed of, may pose substantial hazards to human health and the environment (Table 1.2). At any stage of the management process, a chemical waste may be designated by law as a hazardous waste (Chapter 12). Improper disposal of such waste streams in the past has created a need for very expensive cleanup operations (Tedder and Pohland, 1993). Correct handling of such... 

The Resource Conservation and Recovery Act (RCRA) was enacted in 1976 and was revised substantially by the Hazardous and Solid Waste Amendment (HSWA) of 1984 (40 CFR pts. 260-280). The RCRA regulates the management of solid wastes that are hazardous. The definition of solid wastes in these regulations generally encompasses all discarded materials (including solid, liquid, semisolid, and contained gaseous materials) and many secondary materials (e.g., spent solvents, byproducts) that are recycled or reused rather than discarded [3]. Products such as commercial pesticides are not ordinarily solid wastes, but they become solid wastes if and when they are discarded or stored, treated, or transported prior to such disposal.
