conditions present in many nuclear waste types. For example, inorganic ion-exchangers have shown significant Strontium uptake
from pH 1.9 to 14. In contrast to organic ion-exchangers, inorganic ion-exchangers are not synthesized via complex multi-step
organic synthesis. <strong>The</strong>refore, inorganic ion-exchangers are substantially more cost-effective when compared to organic ionexchangers
as well as CST.

SESSION 27 - WASTE MINIMIZATION, AVOIDANCE AND RECYCLING
1) A MODEL FOR A NATIONAL LOW LEVEL WASTE PROGRAM - 16372
James Blankenhorn, URS - Washington Division (USA)
A national program for the management of low level waste is essential to the success of environmental clean-up, decontamination
and decommissioning, current operations and future missions. <strong>The</strong> value of a national program is recognized through procedural
consistency and a shared set ofresources. A national program requires a clear waste definition and an understanding of waste
characteristics matched against available and proposed disposal options. A national program requires the development and implementation
of standards and procedures for implementing the waste hierarchy, with a specific emphasis on waste avoidance, minimization
and recycling. It requires a common set of objectives for waste characterization based on the disposal facility’s waste
acceptance criteria, regulatory and license requirements and performance assessments. Finally, a national waste certification program
is required to ensure compliance.
To facilitate and enhance the national program, a centralized generator services organization, tasked with providing technical
services to the generators on behalf of the national program, is necessary. <strong>The</strong>se subject matter experts are the interface between
the generating sites and the disposal facility(s). <strong>The</strong>y provide an invaluable service to the generating organizations through their
involvement in waste planning prior to waste generation and through championing implementation of the waste hierarchy. Through
their interface, national treatment and transportation services are optimized and new business opportunities are identified.
2) CEAS CONTAMINATED LEAD RECYCLING ROUTES - 16011
Marc Butez, Frédéric Hornung, CEA (France)
A route of recycling and valuation of contaminated lead has been in service in the CEA (French Energy Atomic Commission)
since May 2003.
<strong>The</strong> opening of this route required 3 years of instruction of file preparation with the nuclear safety authorities (French regulator)
plus a public inquiry.
Since July 2005 this route has been opened to all the operators of the French nuclear power (CEA, AREVA and EDF).
<strong>The</strong> authorized maximum quantity is 400 tons a year. <strong>The</strong> contaminated lead coming from nuclear installations is decontaminated
at first by fusion in a furnace of the equipment decontamination workshop (ADM) located on the nuclear site of the CEA
MARCOULE.
Lead pieces allowed into the furnace have to have a dose rate lower than 0,3 mGy / hour. At the end of the process the lead
ingots of a mass included between 400 and 500 kg have to have an α and ß activity lower than 1 Bq / g
<strong>The</strong>se ingots are then transformed into biological shieldings for the nuclear industry by an industrial company located in Marseille.
Since the starting of this route about 1280 tons of lead were decontaminated in the ADM and more than 600 tons were valued
and recycled at the various operator’s of nuclear powers CEA and AREVA which corresponds to approximately one hundred of tons
a year for a potential of 400 tons / year.
Having starte essentially with some lead from the CEA facilities of the Marcoule site, the route began to receive lead from the
other sites of the CEA and AREVA NC in 2008.
3) WASAN: A METHODOLOGY FOR ANALYSING WASTE MINIMISATION - 16347
Neil Blundell, Nuclear Installations Inspectorate (UK); Duncan Shaw, Aston Business School (UK)
This paper presents a new methodology called Waste And Source-matter ANalyses (WASAN) which helps a group to analyse
waste-production and build actions to minimise avoidable waste. Designed for Licencees of nuclear facilities as Health and Safety
Executive (HSE) Guidance on what constitutes good practice, WASAN uses lessons from Systems Thinking, Waste Management
Hierarchy, Hazard Operability (HAZOP) Studies, As Low As Reasonably Practicable (ALARP), simulation modelling and sensitivity
analysis. <strong>The</strong>se lessons are used to support groups when developing plans to reduce avoidable waste production. We report
on the development of WASAN and its use in three workshops.
This paper reports progress on the development of waste management guidance for the HSE and does not currently represent
its final regulatory view.

4) DELIVERING STEP CHANGE IMPROVEMENTS TO UK LOW LEVEL WASTE STRATEGY - 16188
Jason Dean, National Nuclear Laboratory (UK); David Rossiter, Low Level Waste Repository (UK)
<strong>The</strong> UK Nuclear Industry continues to produce significant quantities of Low Level Waste (LLW) as decommissioning projects
generating waste become more prevalent. Current infrastructure and projected increasing waste volumes will deliver a volumetric
shortfall of storage capacity in the near future. Recently established as a stand alone site licence company, the Low Level Waste
Repository (LLWR) near Drigg, in West Cumbria (formerly operated and owned by British Nuclear Group) is tasked with managing
the safe treatment and disposal of LLW in the UK, on behalf of the Nuclear Decommissioning Authority (NDA).
