This publication provides the report of the 3rd Research Coordination Meeting (RCM) of the IAEA Coordinated Research Project (CRP) on "Studies of Advanced Reactor Technology Options for Effective Incineration of Radioactive Waste". This CRP was initiated upon expressed Member States’ needs to deepen the understanding of the dynamics of transmutation systems, e.g. the accelerator driven system, especially systems with deteriorated safety parameters, qualify and specify the range of validity of the available methods to simulate and design such systems, and formulate requirements for future theoretical developments.

The 3rd RCM hosted by the Indira Gandhi Centre for Atomic Research (IGCAR) in Chennai, India, from 15 to 19 January 2007.

The main objective of the CRP is to study innovative technology options for incinerating/utilizing radioactive wastes. The CRP’s benchmarking exercises focused on eight innovative transmutation “Domains”, which correspond to different critical and sub-critical concepts or groups of concepts:

  1. Critical fast reactor, solid fuel, with fertile
  2. Critical fast reactor, solid fuel, fertile-free
  3. ADS, solid fuel, with fertile
  4. ADS, solid fuel, fertile-free
  5. Critical reactor and ADS, molten salt fuel, with fertile
  6. Critical reactor and ADS, molten salt fuel, fertile-free
  7. Critical fast reactor and ADS, gas cooled
  8. Fusion/fission hybrid system

For each of these Domains, the discussions and inter-comparisons at the 3rd RCM considered the following issues:

  • Reactor-models
  • Scenarios/phenomena
  • Static analyses
  • Dynamic analyses
  • Methods
  • Codes
  • Neutronic data base
  • Thermo physical data base
  • Key findings and further developments needed.
