Magnox ILW strategy
14th May 2015
May 14th 2015

Looking back
• Following consultation, the preferred options identified a regional
approach to ILW storage and FED treatment
• Put on hold until new Magnox/RSRL PBO was in place
• Key inputs from stakeholder workshops remain valid
• Previous input has been considered
• Magnox believes that the consolidation strategy is appropriate
• However – there are some changes to the direction of travel

Our learning from engagement
Key points taken on board:
•
Strategy needs to look at the big picture
and not at sites in isolation
•
Transfers should be made on a regional
basis where practicable
•
The use of rail transport should be
maximised where possible
•
The amount of construction work
undertaken should be minimised where
possible

Current position - strategy reviewed
•
The new contract requires the PBO to review all Magnox strategies and
demonstrate value for the taxpayer
•
The ILW strategy review considered:
–
–
–
–
–
stakeholder feedback from previous engagement
progress and learning from delivery of previous strategies
development of new waste routes/options
new ideas and operational experience brought by the PBO
introduction of two new consolidation options for waste management
treatment of ILW pond skips
packaging of IONSIV cartridges

Scope of review
Plans still require further approvals and
stakeholder engagement
1. ILW packaging
2. ILW interim storage
3. FED management
4. ILW pond skip management (new)
5. IONSIV cartridge management (new)

1. ILW packaging
Delivering value to the taxpayer
New encapsulated self-shielding waste
packages available:
- 6 m3 concrete box, TRU-Shield package
- Same benefits as ductile cast iron
containers but present a significant saving
Changes in packaging strategy:
• Hinkley
• Berkeley (for some waste)

2. ILW interim storage
Making best use of assets on a regional basis
Changes in interim storage strategy:
• Consolidation of ILW from
Sizewell and Dungeness in the
existing ILW store at Bradwell

3. Fuel element debris
Management options considered
•
•
•
•
package for LLW disposal
package for ILW disposal
decay storage for LLW disposal
treatment by dissolution
Informed by:
• some sites are well progressed in delivery of some options (eg
Bradwell and Trawsfynydd)
• new waste routes have potentially become available

3. Fuel element debris continued
Pursuing opportunities for new waste routes where appropriate
• Sizewell and Oldbury - change to LLW disposal
• Hinkley - FED characterisation indicates majority of waste is likely
to be ILW - intention to package to allow interim storage on site
• Bradwell - continue with dissolution and investigate additional waste
routes to reduce volume to be dissolved

4. ILW pond skips (new)
Reviewing best options for decontamination of ILW pond skips
• Central skip treatment facility for all
skips from Dungeness, Sizewell and
Oldbury (approximately 175 skips)
• Hinkley as a possible site for the
facility. Facility could be mobile and
move to other sites
• Trial work ongoing at Hinkley to
inform decision making

5. IONSIV cartridge management (new)
Avoid the need for three waste packaging projects
• Transfer of Dungeness and Sizewell
IONSIV cartridges to Oldbury for retrieval
and packaging (less than ten movements)
• Onward transfer to Berkeley for interim
storage
Benefits include:
– reduces dose to the workforce
– enabler to waste consolidation strategy
– saving for taxpayer

Our plans- major benefits
-
Significant savings to the taxpayer (£200m)
-
Minimises construction overall, meaning less
disturbance and fewer transports
-
Minimises dose to workers
-
Takes into account the stakeholder feedback
received previously
-
No additional detriment to the environment
