LA LLW Arisings and Capacity Analysis

Nuleaf Radioactive Waste Planning Seminar12th March 2013

David RossiterHead of National ProgrammeLLW Repository Ltd

The Broader Capacity Challenge• UK 2010 National Inventory

forecast 4.4 million m3 of raw LLW

• Packaging increases volume by factor of 1.5 to 6.4 million m3 (if disposed to LLWR)

• Maximum vault capacity of LLWR is 1.7 million m3

• Repository can last until 2130 – but only if we manage the space wisely:

– Recycling & volume reduction– Alternative solutions for LA LLW

& VLLW

Highly Engineered Vaults at LLWR

• Key workstreams:

• Consulted through LA LLW Working Group

1. Arisings vs. Capacity analysis2. Sellafield onsite disposal feasibility3. Assessment of onsite disposal at other

NDA sites4. Assessment of use of LLW in the LLWR

cap5. Criteria for de-licensing of nuclear sites6. CIRIA coastal erosion of landfills Project

LA-LLW Disposal

VLLW Disposal Site location

• Current UK Facilities:– Augean* Kings Cliffe (National)– FCC* Lillyhall (National)– SITA * Clifton Marsh (National)– Sellafield CLESA (Onsite only)

* LLWR VLLW framework service provides all waste producers with access to these facilities

• Potential Future UK Facilities: – DSRL Dounreay (Onsite only)– SITA Keekle Head (National)– LLWR Reuse in Cap (TBC)– Sellafield Future landfill (TBC)

VLLW / LA LLW Disposal Options

Approach

• National inventory forecasts for LA LLW and VLLW reviewed:

– UKRWI 2010 (All sites)– 2012 Waste Inventory Forms (NDA only)– 2012 Joint Management Plans (NDA only)

• Capacity of existing sites assessed for the period 2012 – 2030 on both a national and regional basis

• Dounreay and CLESA wastes excluded (as onsite only)

• Consult results with VLLW Working Group and supply chain (ongoing)

Conclusions

• Comparing capacity and arisings is not always straightforward!• There is uncertainty in the inventory volumes • There is adequate capacity in the existing Permitted sites until

December 2016• There will be adequate capacity until around 2026-2030 if planning

consents are extended• There is adequate capacity in both northern and southern regions • Analysis does not consider other potential users of these facilities

(e.g. non-nuclear, NORM, etc)• There is a need to improve accuracy of the inventory data with

respect to volumes and classification• Aiming to finalise and publish report in March 2013
