Developed Operational Strategy - Low Level Waste Repository Ltd

LLWR Developed Operational Strategy10009/LLWR/LTP Date: March 2010FIGURE 6 - ILLUSTRATION OF HHSIO LINERThe containers and packages will be designed to ensure that the flexibility of use is maximised and thatthe packages can be used in combination to suit consignor requirements and the physical nature of thewaste. The disposal liner and over-pack will be designed to minimise void space, both internal andexternal. The current void space is approximately 50% (10m 3 of LLW for 20m 3 of vault space). It isanticipated that this approach will have the following benefits:• Significantly increase disposal efficiencies at LLWR• Reduce amount of grouting required• Reduce packaging costs significantly• Facilitate the segregation of waste and application of the waste hierarchyThe LLWR has completed an initiative to re-use 30 HHISOs for transport of LLW and/or segregatedwastes. These containers were surveyed and re-certified for transport. Twelve (12) of these containerswere used to transport the first consignment of segregated metallic LLW to the Studsvik UK Ltd. MRF.Eleven of these HHISOs have been returned to LLWR to be reused or utilised for LLWR generatedwaste. Two further HHSIOs and another container (1/3 height) have been sent to a Swedish MRF andthese will be also be reused when returned to the LLWR.Page 28 of 62
