Ion exchange resins will be encapsulated in a solid matrix which is in direct contact with the waste container. Based on the NIREX report N/104, the container proposed for this waste is the unshielded waste package “500 litre Solids Drum”. A transport container providing an additional shielding not bigger than 285 mm of steel is then required for transport and waste handling in the proposed deep geological disposal facility. Ion-exchange resins can be dewatered or immobilised in a polymer matrix (epoxy) inside this container. Epoxy resins is usually mixed into a container pre-equipped with a stirring device. Epoxy matrix enables a greater quantity of ion exchange resin to be immobilised in the matrix than cement mortar. Note that if the waste containment can be assured by the container itself, no additives need be considered.
EPR UK N° NESH-G/2008/en/0123 REV. A PAGE 107 / 257 Data related to waste processing at production time have been summarized in Table 30. The ion exchange resins are the main secondary ILW produced during the post operational clean-out operations. Some additional secondary ILW, (e.g. activated swarf) will also be produced, depending on the cutting technique used for dismantling the pressure vessel and associated internals but this is not expected to be a significant arising. FIGURE 28: 500 LITRE DRUMS The indicative radiological characteristics in Bq per drum at the production time are given in Table 29.
