Abstracts Session 4
In 2002 the Ministry for Environment of the federal State of Lower Saxony licensed the construction and operation of the Konrad
repository. In addition to the Plan Approval License a Water Law Permit is required for the operation of the repository. It considers
the impact of radioactive as well as non-radioactive harmful substances on the near-surface groundwater. The Water Law Permit
limits the total maximum masses, which are allowed for the Konrad repository.
According to the Water Law Permit the operator of the repository has to register the radioactive and non-radioactive harmful
substances and to balance them. Thus, the Federal Office for Radiation Protection (BfS) as the permit holder had to develop a concept
accordingly. BfS defined threshold values for registering and balancing the harmful substances, which led to a site specific
solution for the Konrad repository.
The Lower Saxony Water Management, Coastal Protection and Nature Conservation Agency (NLWKN) as the responsible
water law regulatory authority examined this concept in order to exclude an adverse…
5) THE HYDROGEOLOGIC ENVIRONMENT FOR A PROPOSED DEEP GEOLOGIC REPOSITORY
IN CANADA FOR LOW AND INTERMEDIATE LEVEL RADIOACTIVE WASTE (w/oP-59285)

A Deep Geologic Repository (DGR) for low and intermediate level radioactive waste has been proposed by Ontario Power
Generation for the Bruce nuclear site in Ontario, Canada. The DGR is to be constructed at a depth of about 680 m below ground
surface within the argillaceous Ordovician limestone of the Cobourg Formation. This paper describes the hydrogeology of the DGR
site developed through both site characterization studies and regional-scale numerical modelling analysis. The analysis provides a
framework for the assembly and integration of the site-specific geoscientific data and explains the factors that influence the predicted
long-term performance of the geosphere barrier. Flow system evolution was accomplished using both the density-dependent
FRAC3DVS-OPG flow and transport model and the two-phase gas and water flow computational model TOUGH2-MP. In the geologic
framework of the Province of Ontario, the DGR is located at the eastern flank of the Michigan Basin. Borehole logs covering
Southern Ontario combined with site specific data from 6 deep boreholes have been used to define the structural contours and
hydrogeologic properties at the regional-scale of the modelled 31 sedimentary strata that may be present above the Precambrian
crystalline basement rock. The regional-scale domain encompasses an 18,500 km2 region extending from…
6) RADIOACTIVE WASTE MANAGEMENT CHALLENGES AND PROGRESS IN IRAQ (wP-59164)

The government of Iraq, through the Ministry of Science and Technology (MoST) is decommissioning Iraqs former nuclear
facilities. The 18 former facilities at the Al Tuwaitha Nuclear Research Center near Baghdad include partially destroyed research
reactors, a fuel fabrication facility and radioisotope production facilities. These 18 former facilities contain large numbers of silos
and drums of uncharacterized radioactive waste and approximately 30 tanks that contain or did contain uncharacterized liquid
radioactive wastes. Other key sites outside of Al Tuwaitha include facilities at Jesira (uranium processing and waste storage facility),
Rashdiya (centrifuge facility) and Tarmiya (enrichment plant).
The newly created Radioactive Waste Treatment Management Directorate (RWTMD) within MoST is responsible for Iraqs
centralized management of radioactive waste, including safe and secure disposal. In addition to being responsible for the uncharacterized
wastes at Al Tuwaitha, the RWTMD will be responsible for future decommissioning wastes, approximately 900 disused
sealed radioactive sources, contaminated debris from the first Gulf War in 1991 and unknown quantities of NORM wastes from oil
production in Iraq.
This paper presents the challenges and progress that the RWTMD has made in setting-up a radioactive waste management program.
The progress includes the establishment of a staffing structure, staff, participation in international…

1) RESEARCH AND TECHNOLOGY DELIVERY AT SELLAFIELD, UK (w/oP-59372)
Mike James, Sellafield Ltd (UK)
This paper provides an overview of research and development which is critical to the successful delivery of our operational
and clean up activities. Today we operate a number of plants supporting the nuclear fuel cycle including two reprocessing plants,
fuel fabrication and associated waste management plants for low, intermediate and high level wastes. Our decommissioning programme
is extensive with challenging and complex programmes of work along side the operational facilities. This involves a prioritised
programme to reduce risk and hazard in former reprocessing and fuel fabrication plants, fuel storage ponds and waste silos
and other related facilities.
Our work covers the span of research, development and technology transfer from investigations into low maturity applications
through to deployment of mature technologies across a range of operational and decommissioning areas. An over view of this will
be provided through examples. Characterisation is one of the key areas for successful operations in the nuclear industry today. Our
work has included commissioning work through others such as the National Nuclear Laboratory to investigate novel technologies
such as the use of muon tomography and implementing HiRad a high radiation field detector. Our work does not just include investment
in novel applications a number of significant…
