There were some concerns that INES was used in a confusing manner, and NAMS was intended to address the perceived INES shortcomings. </p><p>As Smythe pointed out, the INES scale ends at 7; a more severe accident than Fukushima in 2011 or <a href="/wiki/Chernobyl_disaster" title="Chernobyl disaster">Chernobyl</a> in 1986 would also be measured as INES category 7. In addition, it is discontinuous, not allowing a fine-grained comparison of nuclear incidents and accidents. But the most pressing item identified by Smythe is that INES conflates magnitude with intensity; a distinction long made by <a href="/wiki/Seismologist" class="mw-redirect" title="Seismologist">seismologists</a> to compare <a href="/wiki/Earthquake" title="Earthquake">earthquakes</a>.

Furthermore, only the atmospheric release affecting the area <i>outside</i> the nuclear facility is considered for calculating the NAMS, giving a NAMS score of 0 to all incidents which do not affect the outside. The factor of 20 assures that both the INES and the NAMS scales reside in a similar range, aiding a comparison between accidents.
