As of my last update in October 2023, Russia has approximately 11 operational nuclear-powered submarines. This number includes several classes, such as the Borei and Delta IV submarines, which are capable of carrying ballistic missiles. The exact number may vary due to ongoing developments and maintenance in the Russian Navy.
The US, Russia, Great Britain, France, China and (recently) India have nuclear submarines.
As of October 2023, the countries known to possess nuclear submarines include the United States, Russia, China, France, and the United Kingdom. The United States has around 68 operational nuclear submarines, while Russia has approximately 60. China operates around 12, and both France and the United Kingdom have about 10 each. India is also developing its nuclear submarine capabilities and has launched its first operational vessel.
From Wikipedia: Today, six countries deploy some form of nuclear-powered strategic submarines: the United States, Russia, France, the United Kingdom, People's Republic of China, and India Several other countries, including Argentina and Brazil, have ongoing projects in different phases to build nuclear-powered submarines.

As of end of 2010, the Russian Navy included 12 strategic submarines of four different types. The submarines can carry 160 sea-launched ballistic missiles (SLBMs) that can carry 576 nuclear warheads.
The PLA navy has more than 225,000 personnel and is thought to have as many as 70 submarines, 10 of them nuclear-powered
Russian submarines are primarily built at several key shipyards, with the most notable being the Sevmash shipyard located in Severodvinsk, which specializes in nuclear submarines. Other significant facilities include the Admiralty Shipyards in St. Petersburg, known for conventional submarines, and the Rubin Design Bureau, which designs many of Russia's submarines. These shipyards play a crucial role in maintaining and expanding Russia's naval capabilities.

USA has the most nuclear submarines
Nuclear submarines are primarily manufactured by a few specialized defense contractors, with the most notable being General Dynamics Electric Boat and Huntington Ingalls Industries in the United States. Other countries also produce their own nuclear submarines, such as Russia's Rubin Design Bureau and the UK's BAE Systems. These companies design, engineer, and construct submarines equipped with nuclear propulsion systems for military purposes.
