DHS has "discovered" what we already noted around here about a month ago: a hajji-sized nuke won't be big enough to take DC out completely. The bit about the fallout is a new item, though. Still, not enough to change our personal, notional, outcome: on a garden variety week day, Ellen's likely screwed, I'll probably make it, and Olivia would be fine. Weekends when we're not downtown would not be directly disrupted, but having this go off when we're in the Natural History museum would be... bad.
