Why Soviet titanium submarines were difficult to recycle

How much titanium from post-Cold War Soviet submarines was recycled?

Less than might be expected: dismantling the hulls was difficult, and a follow-up reports radioactive contamination on some boats.

A titanium pressure hull is difficult to dismantle for reusable metal. That work limits how much of a retired submarine's titanium can be recovered. A viewer also reports unexpectedly radioactive titanium on a troubling number of boats, including vessels without a recorded accident in the exchange. The answer links this reported contamination to reactor problems. Both dismantling difficulty and radioactive material complicate the comparison between the hull's theoretical value and practical salvage.
