First Announcement for a 2nd Legacy Workshop:“Regulatory Supervision of Legacy Sites: the Process fromRecognition to Resolution”
Organised by the Norwegian Radiation Protection Authority
Lillehammer, Norway, 21-23 November 2017

Background
The value of cooperation on regulatory supervision of legacy sites is evident from several existing
international initiatives and roles of ICRP, IAEA, NEA and IUR. Recent evaluation of complexity ofthis subject was also done through expert discussions and by sharing the experience at aninternational workshop “Regulatory Supervision of Legacy Sites: from Recognition to Resolution1”,
organized in 2015, by the Norwegian Radiation Protection Authority (NRPA). Conclusions from thisworkshop highlighted a substantial gap between theory and good practice, and suggested thatfurther international guidance on practical application would be valuable.
Since that meeting, the ICRP has set up a Task Group (TG98) to clarify the application of theCommission’s recommendations to exposures resulting from contaminated sites from pastindustrial, military and nuclear activities. The NEA has set up a related Expert Group on Legacy
Management (EGLM), to assist member countries in deriving practical interpretation of genericradiation protection guidance document to nuclear legacy site management, and support thedevelopment of international guidance specific to regulatory supervision of nuclear legacy sites. At
the same time, NRPA has maintained substantial ongoing bi-lateral cooperation activities with sister
Authorities in the Russian Federation, central Asian countries and Ukraine. These bilateral activities
strongly contributed to the results of the first phase of the IAEA Forum on Regulatory Supervision ofLegacy Sites Forum (RSLS) and supports a new IAEA network: The European and Central AsianSafety Network (EuCAS), to support the strengthening of the nuclear and radiation safety
infrastructure. The significant support of IUR in identifying research needs, radioecologicalinnovation and liaising the particular scientific outputs with relevant international organizations,focused, among others, on regulations and radiation protection has been given internationallythrough several IUR’s task groups.
These developments have highlighted the importance of a well-established process for legacy
management. Accordingly, this has led to an initiative to hold a 2nd international legacy workshop,
entitled “Regulatory Supervision of Legacy Sites: the Process from Recognition to Resolution”,
organised by NRPA in cooperation with ICRP, IAEA and NEA.

Objective and Topics of Interest
The overall objective of the workshop is to extend the sharing of experience on all the specific issues
in the process of practical regulation and management of a wide range of nuclear and radiationlegacies. Providing a forum for discussion of good practice and comparison of lessons learned will
help in further implementation and maintenance of more efficient regulatory supervision of legacy
sites worldwide.
Therefore, addressing issues raised at the first workshop and during on-going work, the following
topics will be discussed:




Support for development of a common methodology describing a comprehensive process
for legacy management and regulation.
Practical experience and lessons learned in hazard characterization, risk identification andmanagement.Encouragement of proportionate management of different risks and overall
optimization.
Harmonisation of protection objectives, and assessment methodologies and practice, while
creating locally optimised procedures and solutions.
Harmonization of requirements for efficient inspections and monitoring of sources andenvironment after clean-up or remediation activities.
Coordination among regulatory authorities and executive organisations, including thoseresponsible for other hazardous substances.
Sharing underpinning scientific information, which supports sites characterization anddecision making on the introduction and ending of countermeasures, remediation
techniques and waste management.
Identification of further research needs for appropriate regulatory supervision.
Engagement of stakeholders and effective communication measures at each stage of legacy
management as part of an overall transparent and traceable legacy management process.

The scope of the workshop includes the full range of issues linked to regulatory supervision of
nuclear and radiation legacies, encompassing the entire process from recognising that a legacy exists
to complete resolution of safety and protection issues associated with its management.
Participants will have a major opportunity to hear about and contribute to the latest and on-goingdevelopments to understand and further document the process from legacy recognition toresolution. It is planned to document the results of the 2nd Workshop as before1 and include
recommendations for further international engagement and cooperation.
Participation
Organizations with special interest in scientific research and regulatory supervision of legacy sites
are invited to participate and/or give presentations. Presentations covering for advances inradioecological models and methods, regulatory requirements (doubts) and good practice in termsof scientific analysis, examples of radioecological supportive role in regulatory decision making at
legacy sites are welcome.
Next steps
To express interest in attendance, propose a presentation, or request further information, including
support for visa to Norway if needed, please contact Malgorzata.k.Sneve@nrpa.no andJelena.Popic@nrpa.noProvisionally, we plan to develop and distribute a more detailed workshop program by the end ofMay, and so we politely request replies at your earliest convenience.
