Agenda
• Background • Current decommissioning safety standards • Other publications that complement these safety
standards• Proposed changes to decommissioning safety
standards• Challenges related to revising these safety
standards and reports• Application of the safety standards• Summary
IAEA 33
Background: Mandate
Article IIIPara A.6. The Agency is authorized to establish or adopt …standards of safety for protection of health and minimization of danger to life and property, and to provide for the application of these standards …”
Article VIIIThe agency shall take positive steps to encourage the exchange among its members of information relating to the nature and peaceful uses of atomic energy and shall serve as an intermediary among its members for this purpose.
*****The IAEA is bound by statute to apply the safety standards to work carried out with IAEA funds.
IAEA 44
Background: History of the Programme
• 1957: IAEA created.
• 1973: IAEA/NEA consultancy on decommissioning
• Late 1980s: Radioactive Waste Safety Standards (RADWASS) Programme established.
• 1996 (January): Department of Nuclear Safety and Security created.

Background: IAEA International Safety Documents
Safety Standards: Fundamentals, Requirements,
and Guides
Reviews, Assessments, and Intercomparisons

IAEA 13
Revisions of the Safety Standards (cont’d)
• Review and revise the existing safety guides1. Reflect the new Safety Fundamentals (SF-1)
2. Reflect the new Safety Requirements (WS-R-5)
3. Reflect the outcomes of Athens conference and feedback from standards application
4. Incorporate recent experience and good practice
5. Provide up-to-date detailed practical guidance to regulators, operators and other technical support organisations
