Agreed. It's not the worlds first, by any stretch. The US removes the fuel, the assemblies, and any other component with radiation, then seals up the reactor core It's like saying the UK is the worlds first ship recycler using only 10mm wrenches and working on Tuesdays(obvious sarcasm), or changing one process, when you need to add technicalities you aren't first. The US also removes many parts of the reactor but uses the compartments to use a high pressure keep the nuclear molecules at bay. Worlds first would be discovering how to not have any contamination when recycling.
"It’s a meticulous process. First, the defunct sub is towed to a secure de-fueling dock where its reactor compartment is drained of all liquids to expose its spent nuclear fuel assemblies. Each assembly is then removed and placed in spent nuclear fuel casks and put on secure trains for disposal at a long-term waste storage and reprocessing plant. In the US, this is the Naval Reactor Facility at the sprawling Idaho National Laboratory, and in Russia the Mayak plutonium production and reprocessing plant in Siberia is the final destination."
"Although the reactor machinery – steam generators, pumps, valves and piping – now contains no enriched uranium, the metals in it are rendered radioactive by decades of neutron bombardment shredding their atoms. So after fuel removal, the sub is towed into dry dock where cutting tools and blowtorches are used to sever the reactor compartment, plus an emptied compartment either side of it, from the submarine's hull. Then thick steel seals are welded to either end. So the canisters are not merely receptacles: they are giant high-pressure steel segments of the nuclear submarine itself – all that remains of it, in fact, as all nonradioactive submarine sections are then recycled."

@GOGS-zg7rd It's not the world first, the US among many nations have been doing this for years.

@realburglazofficial2613 Always that one person trying to argue. It's literally how hulls are designed, they need inward pressure on the hull otherwise they start to peel away do to their shape design. This is how ships of all kinds handle so much pressure and movement. They thought they could get away with dry docking the HMS Warrior for example... Didn't go that way. Ships hulls deform out of water and need a lot of bracing. This is what they thought:
"In the event, it was decided to dry-dock her, it being felt that her composite construction, with sharp rise of floors, would allow her to remain out of the water for an indefinite period without the hull losing shape. It was also believed that very light bilge and breast shores would suffice to support the hull and yet allow the ship's lines to be appreciated (Click here for Illustration 10), and that with her unique construction of iron, teak and elm, and being permanently out of the water, there would never be a need for major repairs to the hull in general, nor to the keel in particular."
This is what actually happened...
"In the case of H.M.S. Warrior it was decided to keep the vessel afloat in Portsmouth Harbour."
Dry docking kills ships and is super expensive to keep them going, hence why we don't have many museum ships.
