which guarantee the long-term properties over the periods of 50-100 years. The paper presents the review of activities for manufacturing
of various steel construction elements made of conditionally released steels and activities for realisation of selected scenarios
for reuse of such construction elements. As the starting material for manufacturing of steel elements are the ingots as the
product of melting within the frame of decommissioning radioactive materials management. These ingots are re-melted in industrial
facilities in order to achieve the required physical and chemical properties. Most used technique for manufacturing the steel
construction elements is rolling. As the products considered in scenarios for reuse of conditionally released steels are bars for reinforcement
concrete, rolled steel sheets and other general rolled steel profiles. Lists of elementary activities are…
A-16) THE ASSESSMENT OF THE WASTE MANAGEMENT PLAN TO DECOMMISSIONING
OF CERNAVODA NPP FOR ENVIRONMENTAL IMPACT REDUCTION (wP-59358)
Gheorghe Barariu, National Authority for Nuclear Activity -
Subsidiary of Technology and Engineering for Nuclear Project (Romania)
At present, most of radioactive wastes generated in Romania are due to nuclear activities related to power generation at Cernavoda
NPP Unit 1, commissioned in 1996. By the commissioning in 2007 of Cernavoda NPP Unit 2, nuclear power production
doubled, and as a result the radioactive waste volumes doubled for this industrial activity field.
Nuclear and Radioactive Waste Agency - AN&DR strategy on low and intermediate level waste disposal, has as objective the
commissioning of Final Repository for Low and Intermediate Level Waste - DFDSMA until 2017. This facility is in the responsibility
of AN&DR. On the other hand wastes arising from Cernavoda NPP must be treated in order to achieve the acceptance criteria
of DFDSMA. Corresponding Radioactive Waste Treatment Facility - RWTF is in the responsibility of Cernavoda NPP.
Main objective of the National Policy for radioactive waste management is to assure a theoretic nul negative impact or a practical
minimum reasonable impact of the waste management activities on population and environment.
The volume of low and intermediate level wastes that result from decommissioning of four units CANDU 6 and the environment
impact reduction will be presented in this paper.

A-17) APPLICATION OF THE DATA QUALITY OBJECTIVE PROCESS TO THE PARTIAL
DE-LICENSING AT OLDBURY NUCLEAR POWER STATION (WP -59376)
Denis Buckley, Magnox Ltd, Berkeley (UK)
Early in 2011 Oldbury Nuclear Power station in South West England applied to the Office of Nuclear Regulation (ONR) to delicense
an area of over 30 hectares of licensed land. This is the largest area of licensed land in the UK to undergo this procedure.
As part of the process the site prepared a safety case to support the submission to the ONR. Also there has been a requirement to
do sampling and analysis to characterise the land and show that any radioactive contamination is below the criterion for de-licensing.
This has been achieved through the successful application of the Data Quality Objective (DQO) process which enabled both
site and regulators to agree on the quantity of samples and the degree of analysis. The ONR has now issued the variation to Oldbury
in July 2011 de-licensing approximately 32 hectares of land from regulatory control.
This Paper outlines the process including the decisions and criteria that have been applied to the Sampling and Analysis at Oldbury
and the Treatment and Interpretation of the data.

A-18) MULTI-SITE RISK-BASED PROJECT PLANNING, OPTIMIZATION, SEQUENCING & BUDGETING
PROCESS AND TOOL FOR THE INTEGRATED FACILITY DISPOSITION PROJECT (wP -59394)
Jerel Nelson, Carlos Castillo, Julie Huntsman, Heather Lucek, WorleyParsons; Tim Marks, Omega Consultants (USA)
Faced with the DOE Complex Transformation, NNSA was tasked with developing an integrated plan for the decommissioning
of over 400 facilities and 300 environmental remediation units, as well as the many reconfiguration and modernization projects
at the Oak Ridge National Laboratory (ORNL) and Y-12 Complex. Manual scheduling of remediation activities is time-consuming,
labor intensive, and inherently introduces bias and unaccounted for aspects of the scheduler or organization in the process.
Clearly a tool was needed to develop an objective, unbiased baseline optimized project sequence and schedule with a sound technical
foundation for the Integrated Facility Disposition Project (IFDP).
In generating an integrated disposition schedule, each project (including facilities, environmental sites, and remedial action
units) was identified, characterized, then ranked relative to other projects. Risk matrices allowed for core project data to be extrapolated
into probable contamination levels, relative risks to the public, and other technical and risk parameters to be used in the
development of an overall ranking. These matrices ultimately generated a complete data set that were used in the Ranking and
Sequencing Model (RSM), commonly referred to as the SUPERmodel ,for its numerous abilities to support D&D planning, prioritization,
and sequencing. The SUPERmodel provides rough order-of-magnitude cost estimating,…

B-1) RADIUM REMEDIATION IN CANADA - HISTORY AND PRESENT DAY (w/oP-59157)
Mark Gardiner, Michael Owen, Robert Zelmer, AECL (Canada)
The environmental impact of radium remains even today. Radio-luminescent paints, radium therapy needles, mining and processing
and their associated legacies have long been pursued in France, Canada, the USA and other countries. The management of
these tasks provides a rich and fascinating history as well as successes and lessons learned in environmental remediation. In Canada,
the radium story begins with the discovery of pitchblende on the shores of Great Bear Lake in Canadas far north and its transport
south and refinement in Port Hope, Ontario. In the earliest days, the leading characters were the LaBine brothers, involved in
exploration and mining, and at the recovery and refining end, Carl French and Marcel Pochon, a protégé of Marie Curie, all associated
with the Eldorado Mining and Refining Company .
