Why NDA Prioritisation Process

• Requirement of energy act
• Vehicle for stakeholder engagement
• Provides a framework and common language
  to underpin decisions

 The Prioritisation Process is about
 communication
What Is The NDA Prioritisation
          Process?
• Developed by Prioritisation Working Group
• Only looks at remediation activities
• Process split into three pieces
   • What concerns us most
   • What are we doing about it
   • How do we schedule this in against
     available funding
• Does not replace regulatory due process (Still
  necessary for duty holder to justify)
• Described in detail in NDA procedure EGPR02
  which is on the web (www.nda.gov.uk)
       What Concerns Us Most?

• Safety And Environmental Detriment Score
  (SED)

SED Score =Potential   detriment + Ongoing detriment

   •   Radiological and chemical hazard potential
   •   Facility condition
   •   Uncertainty surrounding waste form
   •   On going impact on the environment as a
       result of facility not being remediated
           Hazard Baseline

• SED Used As Basis Of Hazard Baseline

• Answers question if we looked at our estate
  today which facilities would concern us most

• Allows facilities and sites to be ranked on
  national scale

• Based on site schedules can provide measure
  of progress or assess alternatives

• Linked with waste conversion
