Finland’s Approach to Licensing of Geological Repository

Tero Varjoranta

Director, Nuclear Waste and Material Regulation

STUK

slide2

Status after 30 years´ work

  • Political commitment since 1983
  • Clear roles and responsibilities
  • Up-to-date regulatory framework
  • Site selected with public acceptance 2001, 1st phase under construction
  • Site confirmation ongoing
  • Encapsulation facility and Engineered Barrier System under design, analysis and development,
  • Several safety assessments done

keys to success in finland
Keys to Success in Finland
  • Long term political commitment to resolve the issue
  • Clear liabilities
  • Well defined regulatory framework
  • Sustainable licensing principles
  • Over 30 years step-by-step regulatory process and implementation
  • Clear and well functioning funding scheme
  • Discipline

Tero Varjoranta

most important clear political commitment to resolve the issue
Most important: Clear political commitment to resolve the issue
  • Government’s strategic Decision in Principles 1983, -91, -95
  • Only safe can be built, safety can not be compromised by other requirements or demands
  • Three step licensing
    • Decision-in-Principle: Public and political acceptance, local veto-right
    • Construction license and Operating license: Safety technical issues

Tero Varjoranta

sustainable licensing principles when developing regulations 1
Sustainable licensing principles when developing regulations (1)
  • “We must take care of our waste”
  • We must not leave nuclear waste as a burden to future generations
    • No future detriments exceeding currently acceptable levels
  • Use of today’s proven and robust technology and defence-in-depth principles
  • Being transparent, open and competent
    • International cooperation, but able to manage our nuclear waste without foreign support
  • Passively safe repository and no reliance on long-term surveillance
  • Retrievable, but safe and protective
  • No unjustified delays in the implementation process

Tero Varjoranta

sustainable licensing principles when developing regulations 2
Sustainable licensing principles when developing regulations (2)
  • Robust passively safe repository system: natural and engineered barriers
  • Radiation protection criteria specified separately for different time periods (Operational period, reasonably predictable future, era of extreme climate changes, farthest future)
  • Long time frame cycles (~100 000y) manageable in old and stable Finnish bedrock
    • Olkiluoto bedrock, where repository 1st phase is under construction, has experienced 19000 of these time cycles, including many glacial cycles (in Finland scientific traces seen from 7 glaciations)
    • mechanically stable
    • chemically stable
    • mosaic-type structure

what happens next in licensing
What happens next in licensing?
  • 2000/2001 Decision in Principle: the Finnish Society accepted the Olkiluoto Repository
  • 2009 November: EU-27 Peer Review to STUK
  • 2012 Construction License submittal
    • Authorization to construct deposition tunnels, deposition holes and other underground facilities
    • Authorization to construct encapsulation plant& EBS components
    • No nuclear waste to be introduced into repository
    • Pre-license application (“maturity test”) by the end of 2009
  • 2020 Operating License submittal
    • Introduction of nuclear waste into encapsulation and repository
    • Fixed period with full safety review at 15 y intervals (or as specified in license)
