Nuclear submarines are constructed using specialized materials to withstand extreme pressures and provide durability. High-strength steel, often in the form of HY-80 or HY-100, is commonly used for the hull to ensure resilience against deep-sea conditions. Additionally, special alloys and composites are utilized for components like the reactor and propulsion systems, while radiation-shielding materials, such as lead or polyethylene, help protect the crew from nuclear radiation. Advanced insulation materials are also employed to minimize noise and maintain thermal efficiency.
The United States was the first country to build a nuclear submarine, and that boat was named the USS Nautilus.
almost anyone that can get the materials
The first operational nuclear submarine, the USS Nautilus(SSN-571), was developed by the United States. The idea of a submarine dates far back in history, but the technology required to actually build an operational undersea boat is relatively new. Applying nuclear power to this concept is newer still, and it had to wait until nuclear power could be harnessed in the form of a safe and reliable nuclear reactor. A link can be found below for more information.
Current-generation U.S. nuclear submarines are likely to cost around $2 billion each to construct (after including R&D costs).
It can't explode like a nuclear bomb. It could have a steam explosion, as can any steam power plant. It is also possible for it to build up hydrogen gas if it runs too hot and damages its fuel rods, the hydrogen could explode.
All the facilities used by the US to prepare the materials for nuclear weapons, build nuclear weapons, design and test new nuclear weapons. This is all lead by the Department Of Energy.
The construction time for a submarine can vary significantly based on its type and complexity. Generally, building a conventional submarine may take around 2 to 5 years, while nuclear submarines can take 5 to 10 years or more. Factors influencing this timeline include design specifications, technological advancements, and the availability of materials and skilled labor. Additionally, military submarines often undergo extensive testing and trials, which can extend the overall timeframe.

Considering the fact that any competent Physics Grad student using publicly available data could design a workable fission bomb (getting the materials to build it is another issue) having a yield comparable to the ones detonated in WW2; it is impossible to ban nuclear weapons. If a country wanted them it will take them roughly 4 years to build the nuclear materials processing infrastructure to make the needed materials.
Theygot the idea from the fishes to build a submarine. As fishes have swim bladder they kept ballast tanks in the submarine.
