waste from the UCP. Also, we investigate the characteristics of chemical leaching for removal of radi<strong>on</strong>uclide from the fine cement<br />
powder as a radioactive waste produced during the course of the mechanical crushing and milling to minimize the final radioactive<br />
waste volume for disposal. Chemical leaching of the radioactive fine cement powder was effective in HNO 3 soluti<strong>on</strong>. <str<strong>on</strong>g>The</str<strong>on</strong>g> removal<br />
efficiency for the fine cement powder c<strong>on</strong>taminated with uranium compound was achieved by up to 97%.<br />
SESSION 7 - NATIONAL AND INTERNATIONAL ER PROGRAMS<br />
1) EXPECTATIONS FOR MANAGING CONTAMINATED GROUND AND GROUNDWATER:<br />
DEVELOPING A COMMON VIEW OF NDA AND REGULATORS - 16252<br />
Anna Clark, NuclearDecommissi<strong>on</strong>ing Authority (UK)<br />
<str<strong>on</strong>g>The</str<strong>on</strong>g> management of c<strong>on</strong>taminated ground and groundwater is a notable c<strong>on</strong>tributor to the challenge we face in cleaning up the<br />
legacy of the UKs civil nuclear industry in a safe, cost-effective and envir<strong>on</strong>mentally resp<strong>on</strong>sible manner. To facilitate this missi<strong>on</strong>,<br />
the Nuclear Decommissi<strong>on</strong>ing Authority and Regulators have elected to try and document our comm<strong>on</strong> expectati<strong>on</strong>s for the management<br />
of c<strong>on</strong>taminated ground and groundwater arising <strong>on</strong> and extending off nuclear licensed sites in the UK.<br />
<str<strong>on</strong>g>The</str<strong>on</strong>g> aims are to:<br />
• speak in <strong>on</strong>e voice about land quality management, both outlining our comm<strong>on</strong> expectati<strong>on</strong>s and explaining any differing<br />
expectati<strong>on</strong>s where c<strong>on</strong>sensus is difficult;<br />
• act as the glue between existing NDA and regulatory principles and legislati<strong>on</strong>;<br />
• interpret principles to ensure they are unambiguous and implementable, therefore facilitating forward planning of programmes<br />
and deliverables;<br />
• clarify practical and strategic links between land quality management and related topics such as waste management and<br />
site end states, including delicensing;<br />
• provide a framework for dialogue against which progress in land quality management can be mapped; and,<br />
• promote positive acti<strong>on</strong> to deliver hazard reducti<strong>on</strong> in a proporti<strong>on</strong>ate and sustainable manner.<br />
To achieve the above aims, this paper outlines the development of our comm<strong>on</strong> view <strong>on</strong> the optimum approach to issues such<br />
as the c<strong>on</strong>trol of c<strong>on</strong>taminated ground and groundwater, justifying implementati<strong>on</strong> or deferral of land remediati<strong>on</strong>, and defining<br />
interventi<strong>on</strong> and remediati<strong>on</strong> standards.<br />
2) THE GOVERNMENT OF CANADA’S PROGRAMMES FOR RADIOACTIVE WASTE<br />
CLEANUP AND LONG-TERM MANAGEMENT - 16133<br />

<str<strong>on</strong>g>The</str<strong>on</strong>g> Government of Canada’s 1986 Policy Framework for Radioactive Waste Management establishes that waste owners are<br />
resp<strong>on</strong>sible for the management of their radioactive wastes. This includes the planning, funding, and implementati<strong>on</strong> of l<strong>on</strong>g-term<br />
waste management initiatives. Within this c<strong>on</strong>text, the Government has established three separate programmes aimed at addressing<br />
the l<strong>on</strong>g-term management of radioactive wastes for which it has accepted resp<strong>on</strong>sibility.<br />
<str<strong>on</strong>g>The</str<strong>on</strong>g> largest of these programs is the Nuclear Legacy Liabilities Program (NLLP). <str<strong>on</strong>g>The</str<strong>on</strong>g> objective of the NLLP is to address certain<br />
radioactive waste and decommissi<strong>on</strong>ing liabilities resulting from 60 years of nuclear research and development at Atomic Energy<br />
of Canada Limited sites in Canada. In 2005, the Government recognized this liability in its Public Accounts and, in 2006, it initiated<br />
the first $520 milli<strong>on</strong> 5-year work plan of what is expected to be a 70-year strategy. <str<strong>on</strong>g>The</str<strong>on</strong>g> costs of implementing the full strategy<br />
are estimated at $6.8 billi<strong>on</strong> (2005$).<br />
Canada’s Historic Waste Program is a sec<strong>on</strong>d program that is designed to address low-level radioactive wastes across Canada<br />
that are not managed in an appropriate manner for the l<strong>on</strong>g-term and for which the current owner can not be held resp<strong>on</strong>sible. <str<strong>on</strong>g>The</str<strong>on</strong>g>se<br />
wastes mainly emanate from the 1930’s and the very early days of nuclear industry in Canada when radioactive ores were mined<br />
and transported l<strong>on</strong>g distances for processing. While the Historic Waste Program has been in place since 1982, the Government of<br />
Canada launched the Port Hope Area Initiative in 2001 to deal with the bulk of this envir<strong>on</strong>mental problem.<br />

Within the framework of the “Co-ordinati<strong>on</strong> Network <strong>on</strong> Decommissi<strong>on</strong>ing of Nuclear Installati<strong>on</strong>s Project (2005- 2008)”<br />
funded by the European Community a first editi<strong>on</strong> of EURSSEM has been developed to promote comm<strong>on</strong> understanding of key<br />
issues in the development of a strategy, implementati<strong>on</strong> and executi<strong>on</strong> of a programme to remediate radioactively c<strong>on</strong>taminated<br />
sites.<br />
<str<strong>on</strong>g>The</str<strong>on</strong>g> objective of EURSSEM is to describe and provide a c<strong>on</strong>sistent c<strong>on</strong>sensus informati<strong>on</strong> and guidance <strong>on</strong> strategy, planning,<br />
implementati<strong>on</strong> and executi<strong>on</strong> of stakeholder involvement, performing, and assessing radiological soil surface and groundwater<br />
(final) status surveys to meet established dose- or risk-based release criteria, and/or remediati<strong>on</strong>, restorati<strong>on</strong>, reuse and stewardship<br />
objectives, while at the same time encouraging effective use of human, raw material and financial resources.<br />
To be able to provide a c<strong>on</strong>sistent guidance and leading practices to involved participants (stakeholders) in a remediati<strong>on</strong> programme<br />
for radioactively c<strong>on</strong>taminated sites, an extensive literature study has been performed to collect important documents that<br />
have been produced in this field by the <str<strong>on</strong>g>Internati<strong>on</strong>al</str<strong>on</strong>g> Atomic Energy Agency (IAEA), the SAFEGROUNDS Learning Network,<br />
Multi- Agency Radiati<strong>on</strong> Survey and Site Investigati<strong>on</strong> Manual (MARSSIM) and other nati<strong>on</strong>al and internati<strong>on</strong>al institutes.<br />
EURSSEM incorporates informati<strong>on</strong> provided in those and other documents to c<strong>on</strong>duct all acti<strong>on</strong>s at radioactively ted and potentially<br />
radioactively c<strong>on</strong>taminated sites and/or groundwater up to their release for restricted or unrestricted (re)use.<br />
