Well you wouldn't want to run around naked there, especially with the amount of radioactive waste that's piled up.
but, I'm pretty sure the nature must be astonishing!
Google is crazy when you're bored:
Navy Yard No. 10 - Shkval
Polyarny
69°12'00"N 33°28'00"E
Navy Yard No. 10 Shkval [Squal], located on the western side of the Murmansk fjord, has about a half-dozen decommissioned nuclear submarines. One of them, a first-generation Echo II, contains a damaged reactor with high radiation levels in the reactor compartment. Under the Arctic Military Environmental Cooperation (AMEC) Program, a product of collaboration between the United States, Russian Federation, and Kingdom of Norway, Polyarny was designated as the pretreatment and storage site for Solid Radioactive Waste (SRW).
The servicing and dismantling of military vessels, in particular nuclear submarines, has created about 20,000 cubic meters of SRW at Polyarny and other Northern Fleet bases. It is estimated that an additional 1000 cubic meters of SRW is being created per year. As arms reduction programs continue this amount can be expected to rise. The radioactive waste storage facilities at this site are full. Consequently, 25-30% of radioactive waste and other contaminants reside in open storage, exposed to the elements.
Socio-economic problems within Russia led to significant local unrest in the shipyards and harbors containing the laid up nuclear submarines. Basic social services were curtailed and salaries went unpaid. This situation led to several demonstrations involving nuclear submarines. In December 1995 and February 1997, employees of the Polyarny shipyard blocked nuclear submarines from leaving the shipyard. These same employees threatened to block traffic in Kola Bay and occupy a nuclear submarine for a hunger strike.
Polyarny, a Closed Administrational and Territorial District (ZATO - zakrytye administrativno-territorial'nye obrazovaniia), was granted the status of a town in 1939. Since 1933 it had been the capital of the Northern Fleet and its development connected with navy base. The town is situated on the coast of the Kola Bay close to the outlet to the Barents Sea. Economy of the town is quite developed; here you can find several enterprises. The positive conditions for the small business undertakings development are created here. Nuclear submarines and ships are repaired in Polyarny. Here you can find the branch of the Knipovich Polar Research Institute of Marine Fisheries and Oceanography. There is the House of Culture in Polyarny.
