[...] NISA didn’t give much (any) explanation of their [Level 4 INES] rating that I saw, but my impression is that it was based on radiation levels measured at the site boundary and the potential for exposure to the general public.
And that was before things took a decided turn for the worse over the weekend.
At this point I think there’s so much that we don’t know about what’s going on, but I think a final rating of at least a 5 is likely. [...]
INES I don’t think anticipated the common cause effects on multiple units – does the fact that they’re dealing with potential fuel damage at 3 or even 4 different units on the same site affect the rating? It certainly complicates the response.
