What the Soviets might do with a captured Bismarck

What happens if Bismarck is captured and taken to a Soviet port?

She likely never sails again, though the Soviets might salvage her 15-inch guns for land use.

The outcome depends on her material condition, but a damaged captured ship would probably never return to sea. Soviet interest in German 15-inch guns for the Kronshtadt programme suggests that the turrets and ammunition technology would not be wholly unfamiliar. One contemplated Kronshtadt armament used six guns of the same general German type in matching turrets, giving Soviet engineers a reason to value the captured battery. Salvaging those weapons for coastal or railway artillery is more plausible than restoring the battleship.
