Doctorow also wrote a story titled "Masque of the Red Death" (yes, like the Poe story) which directly depicts the fate of an isolationist bunker in a post-apocalyptic scenario.
Good story. It is collected in Radicalized (ISBN 978-1-78954-494-7) which contains four of his novellas (including this one) about dystopian futures. I can recommend it.
