Session 7 Abstracts
waste from the UCP. Also, we investigate the characteristics of chemical leaching for removal of radionuclide from the fine cement
powder as a radioactive waste produced during the course of the mechanical crushing and milling to minimize the final radioactive
waste volume for disposal. Chemical leaching of the radioactive fine cement powder was effective in HNO 3 solution. <strong>The</strong> removal
efficiency for the fine cement powder contaminated with uranium compound was achieved by up to 97%.
SESSION 7 - NATIONAL AND INTERNATIONAL ER PROGRAMS
1) EXPECTATIONS FOR MANAGING CONTAMINATED GROUND AND GROUNDWATER:
DEVELOPING A COMMON VIEW OF NDA AND REGULATORS - 16252
Anna Clark, NuclearDecommissioning Authority (UK)
<strong>The</strong> management of contaminated ground and groundwater is a notable contributor to the challenge we face in cleaning up the
legacy of the UKs civil nuclear industry in a safe, cost-effective and environmentally responsible manner. To facilitate this mission,
the Nuclear Decommissioning Authority and Regulators have elected to try and document our common expectations for the management
of contaminated ground and groundwater arising on and extending off nuclear licensed sites in the UK.
<strong>The</strong> aims are to:
• speak in one voice about land quality management, both outlining our common expectations and explaining any differing
expectations where consensus is difficult;
• act as the glue between existing NDA and regulatory principles and legislation;
• interpret principles to ensure they are unambiguous and implementable, therefore facilitating forward planning of programmes
and deliverables;
• clarify practical and strategic links between land quality management and related topics such as waste management and
site end states, including delicensing;
• provide a framework for dialogue against which progress in land quality management can be mapped; and,
• promote positive action to deliver hazard reduction in a proportionate and sustainable manner.
To achieve the above aims, this paper outlines the development of our common view on the optimum approach to issues such
as the control of contaminated ground and groundwater, justifying implementation or deferral of land remediation, and defining
intervention and remediation standards.
2) THE GOVERNMENT OF CANADA’S PROGRAMMES FOR RADIOACTIVE WASTE
CLEANUP AND LONG-TERM MANAGEMENT - 16133
David McCauley, Doug Metcalfe, Marcia Blanchette, TomCalvert, Natural Resources Canada (Canada)
<strong>The</strong> Government of Canada’s 1986 Policy Framework for Radioactive Waste Management establishes that waste owners are
responsible for the management of their radioactive wastes. This includes the planning, funding, and implementation of long-term
waste management initiatives. Within this context, the Government has established three separate programmes aimed at addressing
the long-term management of radioactive wastes for which it has accepted responsibility.
<strong>The</strong> largest of these programs is the Nuclear Legacy Liabilities Program (NLLP). <strong>The</strong> objective of the NLLP is to address certain
radioactive waste and decommissioning liabilities resulting from 60 years of nuclear research and development at Atomic Energy
of Canada Limited sites in Canada. In 2005, the Government recognized this liability in its Public Accounts and, in 2006, it initiated
the first $520 million 5-year work plan of what is expected to be a 70-year strategy. <strong>The</strong> costs of implementing the full strategy
are estimated at $6.8 billion (2005$).
Canada’s Historic Waste Program is a second program that is designed to address low-level radioactive wastes across Canada
that are not managed in an appropriate manner for the long-term and for which the current owner can not be held responsible. <strong>The</strong>se
wastes mainly emanate from the 1930’s and the very early days of nuclear industry in Canada when radioactive ores were mined
and transported long distances for processing. While the Historic Waste Program has been in place since 1982, the Government of
Canada launched the Port Hope Area Initiative in 2001 to deal with the bulk of this environmental problem.

Within the framework of the “Co-ordination Network on Decommissioning of Nuclear Installations Project (2005- 2008)”
funded by the European Community a first edition of EURSSEM has been developed to promote common understanding of key
issues in the development of a strategy, implementation and execution of a programme to remediate radioactively contaminated
sites.
<strong>The</strong> objective of EURSSEM is to describe and provide a consistent consensus information and guidance on strategy, planning,
implementation and execution of stakeholder involvement, performing, and assessing radiological soil surface and groundwater
(final) status surveys to meet established dose- or risk-based release criteria, and/or remediation, restoration, reuse and stewardship
objectives, while at the same time encouraging effective use of human, raw material and financial resources.
To be able to provide a consistent guidance and leading practices to involved participants (stakeholders) in a remediation programme
for radioactively contaminated sites, an extensive literature study has been performed to collect important documents that
have been produced in this field by the <strong>International</strong> Atomic Energy Agency (IAEA), the SAFEGROUNDS Learning Network,
Multi- Agency Radiation Survey and Site Investigation Manual (MARSSIM) and other national and international institutes.
EURSSEM incorporates information provided in those and other documents to conduct all actions at radioactively ted and potentially
radioactively contaminated sites and/or groundwater up to their release for restricted or unrestricted (re)use.
