Drive UK Waste Policy
Waste Strategy for England and Wales
Similar Plans for Wales, Scotland and Northern Ireland
Ionising Radiation Regulations (IRR), Radiological Substances Act (RSA)
UK LLW Policy – 2007
UK Strategy for the Management of Solid LLW from the Nuclear Industry – 2009
Strategy for the Management of Solid Low Level Radioactive Waste from the Non-Nuclear Industry: Anthropogenic Radionuclides – 2012
Strategy for the Management of Waste from (NORM) in the UK- 2014

18. Regulatory Concerns Supply Chain need to be kept Interested
Urgently Need Volumes and Timeline for Generation
Waste Characterisation
Current Data Indicates majority of NORM is Hazardous
But most would categorise as within LALLW (upto 200Bq/g)
Treatment Options
Limited Treatment Options – Incineration & Stabilisation
Limited Radiological Capacity at Treatment Sites
Disposal Options
Landfill – Limited Options
LLWR – Limited Radiological Capacity / Ra226 Undesired

19. Supply Chain Concerns SEPA Strategy for NORM Uncertain Volumes
Waste Declarations Forecasts not forthcoming
Uncertain Decommissioning Timelines
Offshore Decommissioning Timelines not Declared
Fragility of Supply Chain
Enough to sustain Commercial Viability?
Hazardous Content
Heavy Metals (especially Mercury)
Availability of Treatment and Disposal Options
Incineration
Landfill
Engineered Vault – LLWR at Drigg

21. NORM Disposal & Decontamination
Sector leader in modernising hazardous waste management practices
Formed in 2004, the Group is strategically positioned to provide strong commercial and compliance-led solutions in a complex and legislative driven market.
We have developed through a cycle of staged acquisitions, planning and development
Established a specialist waste business in the hazardous radioactive waste markets within the UK Nuclear and Non-Nuclear Industries
We actively engage with our regulators
Promoting (with the ESA) the need for higher standards and the application of the waste hierarchy.
Operating to modern standards and responding to regulatory change.

22. NORM Disposal & Facilities
3 active RSR or RSA permits at ENRMF, Port Clarence and East Kent for Disposal, Treatment and Incineration respectively.
The ENRMF permit allows for disposal of up to 200Bq/g.
Lifetime radiological capacity limits also apply but only a small %age has been utilised to date and >10,000Tes of Radioactive Waste has been disposed since granting of EPR Permit in May 2011.
Port Clarence WRP and Soil Treatment – no specific activity limit applies under the permit however waste must be safe to process with only limited additional controls.
May only receive O&G NORM and in the form of solid, sludge or relevant liquid. The conditions of the non rad permits also apply and >600 te of NORM has been processed since 2012.
Port Clarence Landfill – Exempt Hazardous NORM disposal up to 10Bq/g.
East Kent – Similar restrictions to Port Clarence but may also receive anthropogenic NORM.

23. NORM Disposal & Decontamination Facilities
Dundee – Major MORM Decontamination and Decommissioning Facility
Lerwick – NORM Decontamination and Waste Management
Aberdeeen – NORM Waste and Contaminated Equipment Transfer
Port Clarence – Ad hoc Decontamination facility

24. NORM Treatment Processes
Stabilisation with Waste APCR
Use of APCR with residual lime content
Cement type Pozzolanic reaction used to bind contaminants
Advantages
Existing waste and landfill leachate utilised for treatment
No overall increase in total waste volume
Output residue suitable for disposal as WAC compliant Hazardous Waste
Minimal energy usage for waste treatment – plant runs on electricity generated from landfill gas capture
No offsite transport of secondary waste to final disposal
Limitations
Not suitable for high oil contents >20%
Not suitable for high solubility or volatile organics

25. Waste Acceptance Processes
