The point is that there isn't. I am confident that the members of Radiohead have hardly ever listened to Nirvana, unlike the bands widely accepted as their influences; Just, or for that matter any song Radiohead have ever written, does not sound 'grungy' in the slightest. True, Just and Smells Like Teen Spirit both share a 'clean-guitar sound then drums' intro, and I suppose both feature similar instruments, sadly for you, played in COMPLETELY different ways (could you imagine Kurt Cobain playing like Johnny Greenwood? I sure couldn't), the lyrics, vocal style, tempo, rhythmic features, harmony, and just overall sound are both completely different. Radiohead owe as much to Nirvana as any band in the last 10 years who play guitars, i.e. not much at all.
Deal with it.
Interesting addendum: Listen to the start of 'Pete Jackson is Getting Married' by Less Than Jake (go on, this will be fun). Now listen to the intro to 'In Circles' by Sunny Day Real Estate. Weird, huh? But that is of course because Sunny Day Real Estate were heavily influenced by Less Than Jake.
