SUMMARY
Based on available open source, D and photographic information, it
has been determined that the installations at Petrovka and Severodvinsk are
designed to provide specialized maintenance and support for Soviet nuclear sub-
marines.
Each facility consists essentially of two areas. One area including a large
operations and shop building and quay is primarily for reactor refueling and related
maintenance. The other area consists of several smaller structures, including
eight large tanks, and is designed for the processing, handling, and holding of
radioactive wastes prior to final disposal, The use of such land-based facilities
for these operations represents a significant departure from past Soviet and
U.S. practices,

INTRODUCTION
Approved For Release 2006102107 : CIA-RDP02T06408R001200010041-2
FIGURE 2. PEfROVKA SHIPYARD -
Two facilities for servicing, refueling, and maintenance of nuclear powered
submarines have been identified in the Soviet Union. One is at Petrovka, near
Vladivostok, and one is at Severodvinsk, on the White Sea.. The Petrovka facility
(43-07N 132-20E) is located on the northern tip of land forming the entrance
to the Petrovka Shipyard (Figures 1 and 2). The Severodvinsk facility (6-45N
39-50E) is located near the tip of Yagry Island directly across the Nikolskoye
Estuary from the Severodvinsk Shipyard (Figures 1 and 3). Thus, the Petrovka
facility can readily provide support for the Pacific Fleet, while the one at
Severodvinsk supports the Northern Fleet.
This report presents the results of an effort to determine the specific
functions of these installations. In the United States, no such elaborate shore
facilities are found associated with nuclear submarine maintenance and refueling
operations. Special emphasis has been placed on the structures associated with
processing and storage of radioactive wastes. Comparisons have been made with
Approved For Release 2006102107 : CIA-RDP02T06408R001200010041-2
CIA/PIR -75118
known Soviet radioactive waste disposal facilities, conventional Soviet naval
shipyard construction practices, and related U.S. installations and procedures.
Due to the good quality photography of the facility under construction at
Petrovka, the structures there will be used as the primary basis for comparison.
This approach is possible because the facilities at Petrovka and Severodvinsk are
essentially the same.
Measurements
All measurements have been made by the NPIC Technical Intelligence Division
with the exception of those shown with an asterisk (*) which were made by the
CIA/IAS imagery analyst. The NPIC/TID measurements are considered to be accurate
within + 2 feet for 1-5 foot dimensions; for linear dimensions over 5 feet, + 5
feet or 3%, whichever is greater, and + 5 feet for heights.

Construction activity began at Petrovka, as it did at Severodvinsk, in 1962.
At Petrovka the Soviets did not have land available at that time, and approximately
one year was spent filling an area near the mouth of the harbor. Presently, the
construction status at Petrovka appears to be nearly two years behind that at
Severodvinsk where land was already available.
The photography from provided the first
detailed coverage of the Petrovka site figure Most of the structures ;ere
still in the early stages of construction. Only three structures appeared to be
complete. Foundations for a large building and some of its internal structure
could be seen on the southern end of the land-fill area. To the north, four other
structures could be seen in various stages of construction on the western half of
the filled area. Four of the buildings under construction appeared to have generally
rectangular internal components while the most northern one consisted of four large
circular objects arranged in a rectangular pattern between two walls.
Photography of Q showed significant construction progress (Figure 5).
A long, narrow section along the south side of the large building foundations
appeared to be nearing completion. Its overall appearance is characteristic of
office and/or administration buildings. The roof is essentially flat, and several
rows of windows were visible along the entire southern wall.
Immediately to the east was a new partially completed structure, rectangular
in shape, and divided into two sections. The small northern section appeared to
be subdivided into compartments. The larger southern section was not subdivided
but appeared to contain at least eight horizontal cylindrical objects approximately
20* feet long, arranged side by side, and oriented perpendicular to the long axis
of the building.
The construction on the west side of the site had advanced to a stage permitting
several comparisons to be made. For convenience, an arbitrary nurObering system will
be used in discussing and analyzing the various buildings and their probable functions.
As a group, Buildings 1 through 4 (Figure 5) were probably designed for
processing and storage of radioactive wastes. Figure 6 is a Soviet drawing of an
installation designed for processing and storage of radioactive wastes. 1/ The
drawing portrays an installation containing six cylindrical tanks each
and a section that has several compartments including two cylindrical
structures that are
Building 1 resembles the compartmentalized section of the Soviet installation
described above (Figures 6 and 7). The building is thick walled, and consists of
six sections. Four of the sections appear to be hot cells. They are thick `galled
and constructed as buildings within a building, a feature characteristic of facilities
that handle radioactive materials. Half of the center section is constructed to
form two vertical, circular tank-like cells trhich is approximately
twice the size of the cylindrical structures in the Soviet drawing. Apparently
constructed of concrete, the section would provide effective shielding for radio-
active materials introduced into the cells. Such a building could possibly serve
as a decontamination and purifying area for the resin beds common to nuclear sub-
marines. Photography of the same building at Severodvinsk shows that a road leads
from the quay to the high bay section of the building. It appears that materials
could enter the building at this point and be easily moved to the shielded cells.
There is a passageway within Building 1 leading from the road to the cells. The
remainder of the center section is divided into at least two rooms and possibly
serves as the control area for this probable waste process building.

Building 2, also considered to be a probable waste process building, is not
as heavily constructed as Building 1. Internally, it is divided into several
rooms or sections. Although the photography was of good quality, the complexity
of the building made it difficult to determine its exact internal structures.
The line drawing in Figure 8 portrays the most probable internal design based
on all the available photography. At least five cylindrical tank-like structures
were visible. Shadows and construction materials precluded identification of
additional or similar structures in the adjacent areas.
Building 3 was nearing completion prior to the availability of any good
quality photography, thus making it impossible to determine its internal char-
acteristics; however, its upper portions appear highly dissected. The building
apparently is heavily constructed, and the side walls project past the end at
each corner (Figures 4 and 5). Building 3 has been identified os a probable waste
process building.
Building 4 had been enlarged since the photographic coverage of
On photography of eight large circular structures are visible, and
the building is divided into two equal sections, each containing four of the
circular structures. Both the center dividing wall and the northern wall were
incomplete, leaving the building open and accessible for further internal con-
struction.
The eight circular structures appeared to be pedestal-like bases for tanks
similar to those shown in Figure 6. At Petrovka, the bases are built above ground
at decreasing heights, with the highest bases located near Building 2. The
bases are in diameter, which is approximately twice the diameter of the
tanks in the plan drawing. This is the same dimension ratio as that of the
cylindrical cells in Building 1.
Subsequent photography shows that the tanks built on these bases are identical
to those built at Severodvinsk and are very similar to the liquid radioactive
waste storage tanks at the Dodonovo Atomic Energy Complex, USSR (56-16N 93-33E).
The underground tanks a.t Dodonovo are 120 feet in diameter compared to a diameter
of at Petrovka and Severodvinsk, but their design and construction appears
to be much the same. The tanks consist of a steel lining with a thick concrete
outer covering, and a large center core which probably serves as a support for
the heavy concrete cover (Figure 9). When the buildings are completed and covered
at the shipyards, the end view will be essentially the sa.me as that shown in the
Soviet plan drawing.
One difference is that the drawing shows the tanks built mostly below ground
level. Due to the physical location of the facilities at Petrovka and Severodvinsk,
the water table is most likely too high to allow tanks of that type to be placed
underground. This may also explain the need for the pedestal-type bases and the
enclosing concrete-walked structure.
In Building 1 appeared to be complete (Figure 10). Building 2
was still under construction, and a partially completed overhead conduit connected
Building 2 with Building 4. Four of the large tanks in Building 4 appeared to be
nearly complete. The remaining four are still in the early stages of construction
with little evidence of progress since
Building 6, one of the first buildings at the site, was complete in
and probably serves as an office/support building.

Walls were erected and a roof was partially complete on Building 7 in
where only the foundations had been visible in
The northern section of Building 7 appears to be a large shop area. The roof
supports are spaced approximately 40 feet apart,and no significant partitions or
internal walls are visible. Building 7 is considered to be a combination
operations and shop building. The southern or operational section that faces
the quay will probably serve as office space for the various supervisory and
engineering personnel concerned with the activities at the quay. The shop
section will probably serve as the working area for the specialized maintenance
and support provided there for nuclear submarines. For example, during con-
struction of nuclear submarines, great emphasis is placed on the reliability
and integrity of the various reactor and auxiliary components. Peculiar to the
water-cooled, water-moderated reactors used in marine construction is the
necessity to have special-strength materials in the primary loop that can with-
stand the inherent high coolant temperature and pressure parameters. All these
lines must be assembled in an absolutely clean condition. Auxiliary pumps,
filters and fittings must be steam tested prior to their installation. 2/
Similar operations would be necessary in conjunction with refueling operations.
Various reactor and supplementary mechanisms would probably have to be repaired,
cleaned and then tested in preparation for start-up and dock-side tests. The
shop areas at both Petrovka and Severodvinsk have sufficient space and are con-
structed in a manner that would be very compatible with this type of operation.
The building to the east (Building 8) is complete and possibly serves a
steam pressure-reducing and cooling function. Facilities for servicing nuclear
submarines are known to have such activities. 2/ At Severodvinsk, and probably
at Petrovka, these buildings which contain horizontal, tank-like objects are
served by steamlines.
Building 9 was one of the first structures completed, and is located
approximately 70 feet to the east of Building 6. It probably served as a small
shop and storage building during construction of the facility. It is likely
that it will continue to serve as a support or storage building for the site.
A probable pumphouse (Building 10) has been constructed on the east side of
the site. Figures 11 and 12 show pipelines leading from the building to a water
intake in the harbor.
Three other buildings are now complete at the northern end of the site.
Building 11 remains unidentified. Building 12 is considered to be a probable
administration building. It is identical to a building at the Severodvinsk
facility and very similar to several other buildings that appear to serve an
administrative function in other areas of both shipyards. Building 13 is rather
small by comparison and probably serves as a valvehouse for the steamline which
connects the facility with the main shipyard.

Pipelines
CIAIPIR -75118
The various pipe and steamlines are shown in Figure 12. Building 1 is
served by a probable pipeline that enters on the east side. Another underground
pipeline appears to run from the west side of the high-bay section and enters
Building 2 near the southeast corner.
Besides the pipeline from Building 1, Building 2 is served by a probable
pipeline that enters on the west side near the southwest corner. This pipe-
line leads south for approximately 50 feet and then turns east. It appears
possible that this pipeline leads to the pipeline that runs west from the
probable pumphouse. It is also possible that one or more pipelines connect
Building 2 with Building 4 through the overhead conduit.
One probable pipeline leads toward the east side of Building 4, but no
connection could be seen. Also, the four pipelines that run north from Building
7 and the quay possibly connect with Building 4, but no definite connection
could be established. Two pipelines appear to go under the road between
Buildings 6 and 9 and possibly connect the two. Building 7 is served by one
overhead steamline that enters on the north side near the northwest corner.
It is also possibly served by the four pipelines that run along its south and
west sides.
At present, no pipelines can be seen entering Building 8, but it will
probably be served by at least one of the steamlines under construction that
run eastward parallel to the north side of Building I.
In addition to the two probable pipelines between Buildings 6 and 9, a
probable pipeline leads between Building 9 and the probable pumphouse.
Several pipelines appear to lead away from the probable pumphouse. One
leads to the north, two to the west, and one to the south. On the east side,
5 pipelines lead to the water intake.
Building 11 is served by a steamline that enters on the south side near the
southwest corner. A probable pipeline leads from Building 13, past Buildings 11
and 12, but no connection with the two buildings could be seen. Various other
probable pipelines could be seen,but their connecting or end points could not be
determined.
Generally the facility has an abundance of interconnecting pipes and steam-
lines. Of specific importance is the fact that the four pipelines near the south
and west side of Building 7 could easily be connected with any one or all of
Buildings 1, 2 or 4.

SEVERODVINSK FACILITY
The facility at Severodvinsk has been at least partially operational since
when a possible "N" Class submarine was identified next to the quay.
t a time, the operations and shop building was not complete, but considerable
activity was visible on the western end of the quay.
Figures 14 and 15 show the Severodvinsk facility in the late stages of con-
struction. Nearly all the buildings were complete in 1965 with the exceptions
of Building 2 and the building enclosing the eight tanks (Building 4). Four of
the tanks are covered by a roof and high-bay section which equates to the Soviet
line drawing (Figure 6).
Most of the buildings are essentially the same as those at Petrovka with
the exception of the steam plant and four buildings located near the northeast
corner. This steam plant is apparently the main source of steam for the site,
but it is also connected with a steam plant across the estuary.
Various support vessels have been seen associated with the nuclear submarines.
These include probable radcon%decon barges and ZEYA and "PM-1241' Class ships.
It has been determined that these vessels operate as radiation control, decon-
tamination, and waste disposal units during refueling of the submarine nuclear
power plants. 3/ This operation appears similar to that used in refueling US
nuclear submarines. Decontamination procedures as carried out by the US Navy
employ a specially constructed and highly shielded barge to demineralize and
filter liquid radioactive waste materials. 4/ (see Figure 13)
The Soviet vessels are probably performing a like function, with this possibly
being an interim measure until completion of the Petrovka and Severodvinsk Facil-
ities. On Figure 14, several vessels are visible along the quay including both an "N"
and a possible "H" Class submarine. A shed-like structure can be seen over the
probable reactor compartment of the nuclear submarine similar to those placed
over the reactor compartment of US nuclear submarines during refueling operations.
A probable pipeline leads from the shed-like structure to an object in the center
of the ra.dcon/decon barge inboard of the submarine. Such an arrangement could
easily be used to transfer radioactive liquids from the submarine to the barge.

Table 1 provides a listing by mission of the submarines visible at the
respective berthing places. Various associated support vessels were usually
present also, but they are not included in the table.
Pipelines
Figure 16 portrays the arrangement of the various pipe and steamlines visible
on the available coverage. Four underground pipelines run generally east-west,
parallel to the south side of Building 1. They could continue to the west and
connect with Building 4 but this connection could not be definitely established.
Three pipelines appear to connect Building 1 with the four previously mentioned
at a point south and west of the center of the high-bay section. One pipeline
joins Building 1 with Building 2 (as a.t Petrovka) and another pipeline leads from
Building 1 to Building 6. In addition, Building 6 is also served by an overhead
CIA/PIR -75118
steamline that enters near the center of the east end. An overhead steamline leads
from the steam plant and enters Building 1 on the north side just east of the high-
bay section. A parallel steamline turns to the west, then runs parallel to Building
1 and appears to enter Building 2 at the northeast corner. A probable pipeline
leads from the southeast corner of Building 2 and appears to connect with a possible
extension of the four pipelines that run parallel to Building 1. From there, it
leads west for approximately 150 feet, turns north, and probably enters Building 4
near the center of the east end. A pipeline leads north for approximately 20 feet
from a point near the west end of Building 4 to the road. No further continuation
or connection with any building or another pipeline could be determined.
A pipeline leads from the southeast corner of Building 15 and appears to
terminate near the northwest corner of Building 5, but its exact terminal point
could not be determined.

The operations and shop building is served by two steamlines. One enters on
the north side near the northwest corner, and the other enters on the same side
near the northeast corner. Building 7 is probably served by at least one of the
various underground pipelines, but no positive identification of this could be
made. Building 8 is served by an overhead steamline that enters on the east side.
A pipeline leads north from the northeast corner, turns west, and runs parallel
to Building 7 for approximately 700 feet. No connection or continuation beyond
that point could be seen. Two probable pipelines connect with Building 13. One
appears to connect at the southeast corner, and the other. connects near the north-
west corner. Again, their exact terminal points could not be determined. Three
of the four probable storage buildings (17-19) are connected by probable pipelines
that lead east and west from the ends of the buildings.
COMPARATIVE ASSESSMENT
Generally, the two facilities appear to be the same with respect to building
size, appearance, and function. Differences which have been noted are probably
due mainly to the space available at the time of construction and also the amount
of steam available from the respective shipyards.
It is believed that the facilities at Petrovka and Severodvinsk provide a
land-based waste processing, dilution, and holding system. To quote a Soviet
publication: "In order not to contaminate the surrounding environment with
radioactive wastes which are formed during operation of the ships, the shore
bases are equipped with facilities for the storage of solid wastes and special
installations for the purification of the radioactive wastes (coagulation, ion
exchange, and evaporation). The waste waters which usually contain only slight
amounts of radioactive materials (water from the decontamination showers, clothing
laundry, decontamination water from the central compartment, etc.) are gathered
in special tanks. The waste waters are held in these tanks for a. definite time
during which decay of the radioactive materials takes place. The waters are
unloaded from the special tanks into an auxiliary ship". 2/ They are then
probably dispersed at sea.
Electrical power to both facilities appears to be the same and of the type
considered common to shipyard operations.
The Severodvinsk facility is rather well secured with a perimeter wall and
fencing (see Figure lb). The site at Petrovka. has a natural water barrier on
three sides and lends itself to being easily secured in a similar manner once
the facility becomes operational.
A comparison of the probable waste process buildings a.t Petrovka and
Severodvinsk with radioactive waste process buildings at known Soviet nuclear
energy installations revealed little in the way of external similarities. How-
ever, the thick-walled, concrete type of construction used for the probable process
buildings is characteristic of buildings associated with radioactive materials
handling. Also, the eight steel-lined, concrete tanks common to both facilities
are of the type usually associated with liquid radioactive waste storage.
It was determined that the Petrovka and Severodvinsk facilities were not
similar to any of the Soviet facilities engaged in spent fuel element recovery
processes such as chemical separation, and that an operation of that type would
probably not be accomplished at either Petrovka or Severodvinsk.
