If you just detonate all nukes at their own silos, fallout & nuclear winter will wipe most of life in a few months. If you want to demolish the whole Earth DeathStar-style, nukes won't help.

TTAPS assumed strikes on petroleum facilities and cities. I don't think your scenario fits the assumptions of any study on nuclear winter.
