Did Russell understand Gödel's incompleteness theorems?

Russell was active in philosophy (although no longer in math) for many years after the Gödel's 1931 publication. Gödel's paper were not obscure, and Russell would have been aware of their effect on the Principia and his logicism (and Hilbert's formalism). Logicomix (a partially fictionalized accounts of Russell's life) and common sense suggest that Russell would have grasped Gödel's theorem and its drastic effect to his philosophy. On the other hand writers such as Hofstadter (in "I am a Strange Loop") suggest that Russell never understood Gödel's theorem: going as far as to rudely compare Russell to a dog staring blankly at a TV screen. Is there any writing of Russell's thoughts on Gödel's incompleteness theorem? Is there any reliable historic/biographic source on Russell's understanding of Gödel? Did Russell understand Gödel's incompleteness theorems?
