The Soviets had over 2800 tac nukes floating around from what I recall, Assuming the US destroys 90% and 75% of survivors won't work and 50% of those aren't launched that's still 30 nukes, and frankly I think those numbers are optimistic and the US will miss a lot more than 10% [the Soviets were masters of camouflage and misdirection and Satellite recon was in its infancy and aerial recon was very limited], and that when nukes are bursting on the horizon more officers will decide to launch while they still canI don't think they would remotely that many.
The Soviet military has never been known for showing much individual initiative. And certainly would not regarding launching nuclear weapons.
Not to mention the questions over if most Soviet warheads would work or not. The U.S. found out that 75% of its Polaris warheads would not detonate. I would say that the Soviets had similar problems in the 1960s.
The USSR had 72 SLBMs as well and I think most would survive and launch once they hear radio reports of war
And remember the Americans suffer from failures as well which gives the Soviets more chances of weapons surviving
