Deficiencies in the existing International Nuclear Event Scale (INES)[1] have become clear in the light of comparisons between the 1986 Chernobyl and 2011 Fukushima Daiichi nuclear power plant accidents.[2–4] First, the scale is essentially a discrete qualitative ranking, not defined beyond event level 7. Second, it was designed as a public relations tool, not an objective scientific scale. Third, its most serious shortcoming is that it conflates magnitude with intensity.

Of Disasters and Dragon Kings: A Statistical Analysis of Nuclear Power Incidents and Accidents
This study provides and analyzes a data set that is twice the size of the previous best data set on nuclear incidents and accidents, comparing three measures of severity: the industry standard International Nuclear Event Scale, the Nuclear Accident Magnitude Scale of radiation release, and cost in U.S. dollars.
Calculating nuclear accident probabilities from empirical frequencies
AbstractSince there is no authoritative, comprehensive and public historical record of nuclear power plant accidents, we reconstructed a nuclear accident data set from peer-reviewed and other
Disaster Risk Analysis Part 2: The Systemic Underestimation of Risk
Abstract How risk is defined, the nature of methodologies used to assess risk, and the degree to which rare events should be included in a disaster risk analysis, are important considerations when
Learning how to Learn from Failures: The Case of Fukushima Nuclear Disaster
In this work, it is argued that learning from failures and safety competence should be an important part of the curriculum of Engineering and Management students. The case of Fukushima will be used
Multiple Outlier Detection in Samples with Exponential & Pareto Tails: Redeeming the Inward Approach & Detecting Dragon Kings
Tests are found to be highly sensitive to the correct specification of the main distribution (Exponential/Pareto), exposing high potential for errors in inference and advocating a density mixture approach for detecting clustered outliers.
