1) LOW LEVEL WASTE DISPOSAL REGULATORY ISSUES IN THE US (w/oP-59311)
David James, Thomas Kalinowski, DW James Consulting LLC; Lisa Edwards, Electric Power Research Inst. (USA)
The United States led the international efforts to define disposal requirements for low level radioactive wastes with the publication
of US Regulations governing the disposal of such wastes. The requirements were based on a system of waste classification
based on the concentrations of certain radionuclides considered problematic for the protection of future generations from radiation
exposure. The regulation, itself, was based on a process for the development of new disposal sites defined by the US congress to
provide an equitable distribution of burden to various regions of the US. This process has met with little success in the almost 30
years since its initiation leaving only an incomplete patchwork of disposal options which are primarily dependant on the same
options that existed before the act and regulations were initiated. There is currently a new focus on the basis for some of the regulatory
requirements derived from advances in the understanding of dose impacts from certain radionuclides, improvements in performance
assessment methodologies, the increased use of engineered barriers, the reality of current disposal economies, along with
the failure of the act to conform to expectations. This paper will provide an update on the discussion taking place with a focus on
the technical considerations.
2) TAKING THE UK’S NATIONAL LLW PROGAMME FROM STRATEGY
DEVELOPMENT TO IMPLEMENTATION (w/oP-59059)
David Rossiter, Rachel O’Donnell, LLW Repository Ltd. (UK)
In 2008 UK Nuclear Waste Management Ltd (UKNWM) became the Parent Body Organisation (PBO) at the Low Level Waste
Repository (LLWR) in the UK. LLWR is the primary disposal facility for the UKs LLW, supporting a wide range of industries
across the nuclear power generation, reprocessing, defence, healthcare, education, and oil and gas sectors. One of the key tasks following
the appointment of the new PBO was to work with the Nuclear Decommissioning Authority (NDA) to develop a national
strategy for LLW generated in the UK, predominantly in the NDA estate. The new National Strategy for LLW was required to
address the gap between the forecast waste arisings and predicted capacity at LLWR.
The National Strategy for LLW Management was published in August 2010 following an 18 month development period. The
main focus of the strategy is on three areas:
• Application of the waste management hierarchy to extend the life of LLWR and ensure waste is managed in a risk-based,
fit-for-purpose manner
• Making best use of existing assets such as transport, packaging, treatment and disposal facilities
• Opening up new fit-for-purpose waste management routes to divert waste away from LLWR
Developing a robust strategy is vital to provide…
3) CEA’S WASTE MANAGEMENT POLICY AND STRATEGY. LESSONS LEARNED (w/oP-ICEM2011-59201)
Didier Dall’ava, CEA (France)
Radioactive wastes are generated during operation as well as during the decontamination and dismantling of CEAs nuclear
facility/installation. The safe and responsible management of radioactive wastes at all stages is an essential requirement of the regulatory
system. The management covers the whole sequence of operations starting with the generation of waste and ending with its
disposal. The disposal here means discarding of waste with no intention for retrieval.
It is important to note here that the safety principles and practices that are applicable during the operational phase are also applicable
during the decommissioning phase. As the radioactive waste arising is an inevitable outcome of decommissioning work, all
the regulatory requirements associated with decommissioning remain in force in waste management. This presentation deals initially
with the regulatory standards related to the management of wastes. As the management of radioactive wastes inevitably
includes treatment and conditioning of wastes, following treatment and conditioning of wastes, storage, transportation and eventual
disposal are the logical outcome of the radioactive wastes, processes are at any time improved based on the feedback experience
and the lessons learned.
4) REGULATIONS FOR THE DISPOSAL OF RADIOACTIVE WASTE IN
THE KONRAD REPOSITORY(w/oP-ICEM2011-59105)
Hagen Gunther Jung, Lower Saxony Water Management, Coastal Protection and Nature Conservation Agency
(NLWKN); Gabriele Bandt, TÜV Nord EnSys Hannover GmbH & Co. KG (Germany)
The German Atomic Act required a plan approval process to grant the license for the construction and operation of the Konrad
repository for radioactive waste with negligible heat generation (nearly analog to low/intermediate level waste).
