3 – High Level Long-Lived WasteDistinction is made between the B5 reference packages based on the type of waste and associatedcharacteristics (chemical, radiological, heat transfer):- B5.1/B5.2: these reference packages differ from other cladding waste conditioned in CSD-C intheir higher thermicity and also the presence of technological waste. These reference packages cantherefore be used to study two potentially different CSD-C populations according to theirtechnological waste content: B5.1 reference packages cover technological waste containingorganic matter; B5.2 reference package contains none;- B5.3: this is cladding waste only, with no organic matter, very low thermicity of the waste givenits age;- B5.4: this reference package stands out due to the nature of the waste (magnesium), no organicmatter and no thermicity.Distinction is made in B6 reference packages in the waste type and materials and the envelopegeometries:- B6.1: different envelope geometry from the B6.2 to B6.5 reference packages (B6.2 to B6.5envelopes are identical);- B6.2: cladding waste made up of steel, zircaloy and nickel alloy;- B6.3: magnesium cladding waste;- B6.4: packages containing organic technological waste and generating hydrogen;- B6.5: packages containing metallic technological waste only.Distinction is also made between B7 and B8 reference packages based on the waste type and materialsand the envelope geometries.Reference packages C0.1, C0.2 and C0.3 separate the C0 reference packages based on the type andchemical composition of the vitrified waste, its radiological and heat transfer characteristics and thepackage dimensions.The reference packages and their titles are given in Table 3.3.1. Reference is also made to theparagraphs discussing these reference packages in the previous section.DOSSIER 2005 ARGILE -ARCHITECTURE AND MANAGEMENT OF A GEOLOGICAL DISPOSAL SYSTEM99/495
