Around the city

The Closed Administrative-territorial Formation of Seversk, in addition to the closed city of the same name, includes extra-urban territories, which consist of the settlements: Samus (the administrative center of the extra-urban territories), Orlovka, villages: Kizhirovo, Semiozerki and Inkilshchikova. These towns and villages were part of the Tomsk region until 1997 and a pass is not required to visit them. You can get to these towns and villages (except for Chernilshchikova) from the Tomsk bus station by the Tomsk-Orlovka route (makes several additional stops in Tomsk) and from Seversk by bus route 145. Both bus routes make several trips a day. As for Inkilshchikova, only two pensioners remain from the permanent population there, the rest of the houses are occupied by summer residents. On the territory of BUT there are several more former villages that have already completely turned into holiday villages. Buses from Seversk run to these holiday villages (including Inkilshchikova), and to some, in addition, the same bus "Tomsk-Orlovka". Near the village of Samus and the village of Semiozerki, which are almost fused, there are several large lakes suitable for swimming. Next to one of them there is a boarding house "Seven Lakes", a sauna and a ski base.

 

How to get here

The only way to Seversk is through Tomsk.

By plane
At Tomsk airport, take bus No. 119, take it to Yuzhnaya Square, Tomsk-1 train station, take bus routes 401 or 442. Or take the same 119 bus to any stop on the section of the avenue. Lenin from the ave. Kirov to Lenin Square and transfer to bus number 400, 405 or 442. The travel time depends on the place where you board the bus in Tomsk, the traffic situation (there is a railway crossing on the way), the queue at the checkpoint and where you are going in Seversk (approximately forty minutes to two and a half hours).

By train
At Tomsk-1 train station, take the bus route 401 or 442.

By car
There are nuances here: in addition to the fact that all persons entering the city by car over the age of 12 must have a pass with them, and children must have birth certificates, the driver must have a special "Automatic checkpoint" mark in the pass, without which entry into the city of the vehicle is impossible. If you plan to enter the city by private car, then indicate this in the application for a pass, and upon receipt, ask the issuing person to make this mark in your pass.

Taxi: Most Tomsk taxi companies provide services for the delivery of passengers to Seversk, but it is necessary to inform the dispatcher about the place of travel when placing an order.

By bus
Buses No. 400, 401, 405 and 442 run between Seversk and Tomsk.

On the ship
From the Tomsk river station, the motor ship (flight Tomsk — Krasny Yar) to the Beloborodovo pier. Nuance: Passes to Seversk for new arrivals are issued only at the Central checkpoint, and from the pier, without entering the city, it can only be reached by walking many kilometers along the guarded perimeter. For those who already have a pass, there is a separate checkpoint in the marina area. That is, if you left for Tomsk during the validity period of your pass, you may well return to Seversk by river.

History

On the site of the future city in 1933, a youth labor commune "Chekist" was created, which gave its name to the village in which the first builders of the city lived. After that, this name passed to the area of ​​the city located here today.

The village of Beloborodovo on the territory of the city ceased to exist in the 1980s. The village of Iglakovo still exists today and acquired the status of a microdistrict of the city.

On March 26, 1949, the Council of Ministers of the USSR made a decision to establish a plant near Tomsk for the production of highly enriched uranium-235 and plutonium-239. The new industrial complex was originally called Zauralskaya office of Glavpromstroy or Combine No. 816.

For the construction of the plant, by order of the Minister of Internal Affairs, forced labor camps were organized (correctional labor colony No. 1 of Siblag of the Directorate of Forced Labor Camps and Colonies of the NKVD of the USSR). The prisoners worked not only in industrial facilities, their labor was also used in the construction of residential buildings and urban infrastructure. About 20 thousand prisoners worked on the construction of the closed city and the plant.

The original code name of the city was Mailbox No. 5, because the construction of the city-forming plant was named: PO Box No. 5, in this regard, in common parlance, the city was called "Fifth Postal" or simply "Postal".

Since 1951 - the village of Berezki, where on July 26, 1953, the first Siberian uranium was obtained at the isotope separation plant, part of the Siberian Chemical Combine.

In 1954, the closed settlement was named Seversk, but later in documents for secrecy purposes it was called Tomsk-7.

The second in the world after Obninsk industrial nuclear power plant (NPP-1, also known as the Siberian NPP) with a capacity of 100 megawatts, was built in Seversk in 1958.

The secrecy status was removed from the city in 1989.

In 1993, a radiation accident occurred at the Siberian Chemical Combine, as a result of which radioactive substances were released into the atmosphere, and 1946 people were exposed to radiation. Index on the international scale of nuclear events INES - 4.

Since 1997 - ZATO, which includes, in addition to Seversk, the villages of Samus, Orlovka, Chernilshchikovo, the villages of Kizhirovo, Semiozerki.

 

Geography

Seversk is a closed administrative-territorial formation (ZATO) in Tomsk Oblast, Russia, functioning as a restricted-access city due to its historical and ongoing role in nuclear activities. Established in 1949 as a secret Soviet settlement, it was originally known as Pyaty Pochtovy and later Tomsk-7, remaining unmarked on maps until the early 1990s. The city spans approximately 486 square kilometers and is home to around 108,000 residents, with its geography shaped by the vast West Siberian Plain, making it a relatively flat, riverine urban area embedded in a forested taiga landscape. Its closed status influences geographical access, with entry controlled via six checkpoints requiring special permits, often linked to work, study, or family ties in the area.

Location and Coordinates
Seversk is situated in the southwestern part of Siberia, specifically in the Tomsk Oblast, about 15 kilometers (9.3 miles) northwest of the regional capital, Tomsk. It lies on the right (eastern) bank of the Tom River, which serves as a natural boundary and shapes much of the city's layout. The geographic coordinates are approximately 56°36′N 84°51′E, placing it in the heart of the West Siberian Plain, a massive lowland region that extends across much of western Siberia. This position is roughly in the geographic center of Russia, far from major tourist routes but near natural features like the world's largest swamp complex (the Vasyugan Swamp) to the north and the Altai Mountains several hundred kilometers to the south. Administratively, Seversk is an urban okrug under oblast jurisdiction, equivalent to a district, and its proximity to Tomsk allows for some shared infrastructure, though movement between the two was historically restricted.

Topography and Terrain
The topography of Seversk is characteristic of the West Siberian Plain, one of the largest flatland areas on Earth, with minimal relief and gentle undulations. Elevation averages around 90–110 meters (295–360 feet) above sea level, with the city center at approximately 94 meters. The terrain is predominantly level, with subtle slopes descending toward the Tom River valley, creating a lowland setting that facilitates urban development along the riverbank. There are no significant hills or mountains in the immediate vicinity; instead, the landscape features broad plains interspersed with river valleys and occasional low ridges formed by glacial deposits from the Quaternary period. Surrounding areas include scattered depressions that can form wetlands or small lakes during wet seasons, contributing to a somewhat marshy character in undeveloped zones. Human modifications, such as embankments along the river and industrial zones, have altered parts of the natural topography, but the overall flatness supports dense forest cover and agricultural potential in nearby rural areas.

Hydrology and Water Features
The Tom River is the dominant hydrological feature, flowing southward through the region and serving as a tributary to the larger Ob River, one of Siberia's major waterways. Seversk's position on the right bank means the river acts as a western boundary, influencing local microclimates, recreation, and historically, transportation. The river's width near Seversk varies from 200–400 meters, with seasonal fluctuations due to spring floods from snowmelt and summer rains. Smaller tributaries and streams, such as the Kirgizka River, drain into the Tom nearby, creating a network of waterways that support wetlands and biodiversity. Groundwater resources are abundant in the plain, but environmental concerns arise from past industrial activities, including a 1993 nuclear incident at the Siberian Chemical Combine that released radioactive contaminants, potentially affecting local water quality. The area experiences periodic flooding, mitigated by levees and dams, and the river provides opportunities for fishing and boating in non-restricted zones.

Climate
Seversk experiences a humid continental climate (Köppen Dfb) with distinct seasons, marked by long, harsh winters and short, warm summers. The annual average temperature is about 0.6°C (33.1°F), reflecting Siberia's cold continental influence. Winters are severe, with January temperatures ranging from -21°C to -13°C (-6°F to 9°F), and extreme lows can dip below -40°C (-40°F) during cold snaps. Summers are milder, with July averages around 19.2°C (66.6°F), though highs can reach 30°C (86°F) or more. Precipitation totals approximately 530 millimeters (21 inches) annually, distributed fairly evenly but peaking in summer with thunderstorms. Snow cover persists for 180–200 days a year, from late October to April, with depths up to 1 meter in forested areas. Winds are generally moderate, but blizzards and fog are common in winter, while the flat terrain allows for occasional dust storms in dry periods. Climate change impacts, such as warmer winters and increased precipitation variability, are noted in the broader Siberian region, potentially affecting Seversk's hydrology and vegetation.

Vegetation, Environment, and Land Use
The natural environment around Seversk is dominated by taiga forests, typical of the West Siberian Plain, with coniferous species like pine, spruce, and fir mixed with birch and aspen in deciduous stands. These forests cover much of the undeveloped land, providing habitat for wildlife such as elk, foxes, and various bird species. Wetlands and peat bogs are prevalent in low-lying areas, contributing to carbon storage but also posing challenges for construction. Land use within Seversk is primarily urban and industrial, centered on the Siberian Chemical Combine, which occupies significant territory for nuclear fuel production and reprocessing. Green spaces include parks like the Nature Park and Victory Park, which feature zoos and recreational areas amid the taiga. Environmental aspects are heavily influenced by the city's nuclear history, including the shutdown of plutonium reactors in 2003 and ongoing monitoring for radiation. Despite this, the surrounding forests and river offer outdoor activities like hiking and skiing, though access is limited by the closed status.
