Socio-technical multi-criteria evaluation of long-term spent nuclear fuel management strategies: Supplementary method

François Diaz-Maurin , Jerold Yu, Rodney C. Ewing

The paper presents supplementary information about the framework and method for the socio-technical multi-criteria evaluation (STMCE) of spent fuel management strategies (Sci Total Environ, In press; Available on EarthArXiv at DOI:10.31223/X5459S). The STMCE approach consists of (i) a multi-criteria evaluation that provides an ordinal ranking of alternatives based on a list of criterion measurements; and (ii) a social impact analysis that provides an outranking of options based on the assessment of their impact on concerned social actors. STMCE can handle quantitative, qualitative or both types of information. It can also integrate stochastic uncertainty on criteria measurements and fuzzy uncertainty on assessments of social impacts. This paper presents (1) a detailed discussion about the social multi criteria evaluation framework on which STMCE is based; (2) a review of existing multi-criteria techniques and previous applications to nuclear waste management; and (3) a detailed description of the mathematical procedures used in the STMCE method.
