<i><b>conditioning.</b></i> Those 'operations' that produce a 'waste package' suitable for <br/>handling, 'transport', 'storage' and/or 'disposal'. 'Conditioning' may include the <br/>conversion of the 'waste' to a solid 'waste form', enclosure of the 'waste' in <br/>containers and, if necessary, provision of an 'overpack'.<br/>
<i><b>immobilization.</b></i> Conversion of 'waste' into a 'waste form' by solidification, <br/>embedding or encapsulation.<br/>
'Immobilization' reduces the potential for 'migration' or 'dispersion' of <br/>radionuclides during handling, 'transport', 'storage' and/or 'disposal'.<br/>
<i><b>overpack.</b></i> A secondary (or additional) outer container for one or more <br/>'waste packages', used for handling, 'transport', 'storage' and/or 'disposal'.<br/>
<i><b>packaging.</b></i> Preparation of 'radioactive waste' for safe handling, 'transport', <br/>'storage' and/or 'disposal' by means of enclosing it in a suitable 'container'. <br/>
<i><b>predisposal.</b></i> Any 'waste management' steps carried out prior to 'disposal', <br/>such as 'pretreatment', 'treatment', 'conditioning', 'storage' and <i>transport <br/>activities</i>.<br/>
'Predisposal' is used as a contraction of ‘pre-disposal <i>radioactive waste <br/>management</i>’, not a form of 'disposal'. <br/>
<i><b>pretreatment.</b></i> Any' 'or all of the 'operations' prior to 'waste treatment', such as <br/>collection, 'segregation', chemical adjustment and 'decontamination'.<br/>
<i><b>processing.</b></i> Any 'operation' that changes the characteristics of 'waste', <br/>including 'pretreatment', 'treatment' and 'conditioning'.<br/>
<i><b>segregation.</b></i> An activity where types of 'waste' or material ('radioactive' or <br/>'exempt') are separated or are kept separate on the basis of radiological, <br/>chemical and/or physical properties, to facilitate 'waste' handling and/or <br/>'processing'.<br/>
<i><b>treatment.</b></i> 'Operations' intended to benefit 'safety' and/or economy by <br/>changing the characteristics of the 'waste'. Three basic 'treatment' objectives <br/>are:<br/>
(a) 'Volume reduction';<br/>(b) Removal of radionuclides from the 'waste'; <br/>(c) Change of composition.<br/>
'Treatment' may result in an appropriate 'waste form'.<br/>
If 'treatment' does not result in an appropriate 'waste form', the 'waste' may be <br/>immobilized.<br/>
<i><b>volume reduction.</b></i> A 'treatment' method that decreases the physical <br/>volume of a 'waste'.<br/>
Typical 'volume reduction' methods are mechanical compaction, incineration <br/>and evaporation.<br/>Should not be confused with 'waste minimization'.<br/>
2. [All 'activities', including 'decommissioning' 'activities', that relate to the <br/>
handling, 'pretreatment', 'treatment', 'conditioning', 'storage' or 'disposal' of <br/>'radioactive waste', excluding 'off-site transportation'. It may also involve <br/>'discharges'.] (From Ref. [5].)<br/>" (en)
