The Low Level Waste Repository Permit Application

The disposal of radioactive waste at or from the Low Level Waste Repository (LLWR) is regulated by the Environment Agency.  The LLWR currently holds a Permit under the Environmental Permitting Regulations, allowing it to dispose of and transfer radioactive wastes.  Eden NE has assisted the Low Level Waste Repository Ltd to prepare documents in support of an application to vary its existing Permit.  The application concerns the disposal of solid Low-Level radioactive Waste (LLW) to the LLWR.  The application is based on the revised Environmental Safety Case (ESC) of the Repository.  The ESC documentation can be found on the LLWR website.


Environmental Assessment for Aqueous Discharges Resulting from Magnox FED Dissolution

Tim Soetens and Duncan Jackson have provided support to Magnox Ltd in their evaluation of a potential treatment option for fuel element debris (FED).  Eden NE’s contribution involved the estimation of the potential radiological impacts from aqueous discharges, should FED be subject to dissolution at the sites where FED is currently stored or at alternative sites (optimising the use of resources).  PC-CREAM 08, developed and maintained by Public Health England (PHE), was used to assess doses to potentially exposed groups, local to the sites involved.


Non-Human Biota Assessment of Planned Alternative Active Effluent Discharge Line for Oldbury Site

Oldbury-compartments-for-AEDL-study (200x137px) Tim Soetens and Duncan Jackson have provided support to Magnox Ltd in their evaluation of non-human biota for Oldbury’s planned alternative active effluent discharge line.  This work is a follow-up of an options assessment Eden NE previously undertook for the same site.  PC-CREAM 08, developed and maintained by Public Health England (PHE), was used to assess activity concentrations in local and regional waters.  The ERICA tool was then applied to estimate dose rates to non-human biota.


Westinghouse Springfields’ Integrated Waste Strategy

Eden NE are currently assisting Westinghouse Springfields site to update their Integrated Waste Strategy.  The project draws on the expertise of both in-house and Eden staff, and incorporates recent process changes on site.


 
Scottish Strategy for Intermediate Level Waste

Disposal-Concept (200x131px)Technical experts from Eden NE and EnergySolutions EU Services Ltd. provided support to the Magnox’s Options Development Project for the storage of Intermediate Level Waste for sites in the south and central Scotland, being developed on behalf of NDA. The project explored alternatives to the current strategy, starting from on-site storage of higher activity waste for up to 300 years, followed by consignment of the waste to a near-surface disposal facility in Scotland. All the considered waste streams were assessed based on the availability and maturity of alternative technologies. The project brought together both in-house and external experts in a workshop to review options and refine forward programmes for consideration.
