Sampling Toolbox for Radiological Assessment To Enable Geostatistical and statistical Implementation with a Smart Tactic

The STRATEGIST web tool

  • Guides the expert in handling the problem definition and applying a strategy based on proper data analysis and sampling design.
  • Promotes the application of an integrated characterisation methodology and strategy during nuclear decommissioning and dismantling operations (D&D) of nuclear power plants, post-accidental land remediation or nuclear facilities under constrained environments.
  • Relies on state-of-the art statistical techniques for preliminary analysis and data processing.

The STRATEGIST web tool provides concise descriptions, lists relevant theoretical references, case studies and software implementations for helping the end user to get started, using the STRATEGIST diagrams:

How should this strategy be applied?

  • For the application of this strategy, we recommend all involved parties to familiarize themselves with it, or at least the general workflow. This will ease the discussion on the different objectives and constraints, and create more realistic expectations on the work that has to be done.
  • People involved in the data analysis, and especially the selection of the appropriate methods, should at least have some general notions on all different types of methods discussed here, to enable proper judgement of the different options, and selection of the most appropriate one.
  • Please take into account the following important remarks:
    • This strategy is NOT intended to provide the nonspecialist with a comprehensive mode of operation for the complete process of initial nuclear state characterisation in view of decommissioning.
    • This is only a guideline, and should not be blindly followed. Special circumstances often ask for special solutions, which cannot all be covered by a generic strategy.
    • This strategy can be used to inform people with no or very little experience in statistics about the complexity of the issue, and provide them some relevant background, but it cannot justify not involving people experienced in the matter.

For the vocabulary used in the STRATEGIST tool we refer to the VIM (BIPM, IEC, IFCC, ILAC, ISO, IUPAC , IUPAP et OIML, International vocabulary of metrology – Basic and general concepts and associated terms (VIM), 3rd edition éd., Joint Committee for Guides in Metrology, JCGM 200:2012, 2012).

In the use cases section you can find details on the implementation of the strategy in four different use cases as well as a summary of the lessons learnt.
