VAULT COMPONENTS FOR NEW-GENERATION SUBMARINE REACTORS, USSR (S)
1. (TSR) This report presents a continuation of the analysis of submarine reactor vault components
discussed in a previous NPIC report.' Additional components identified since that report and believed to
be associated with the reactor vault sections are also discussed.
2. (TSR) The vault base sections (Figure 1) were first observed on on 25X1
a rail line leading from a shop building west of the submarine construction hall at Komsomolsk Shipyard
Amur 199 , USSR. On the two base sections were on a rail spur 25X1
adjacent to the two-bay construction hall (Figure 2), and at that time, detailed mensuration was done on the
sections. The outside dimensions of these vaults are centerline measurements), with the= 25X1
meter sides athwartships tapering toat each end. The sections are high above the railcar, 25X1
and the border around the sections is thick (Figure 3). The inside dimensions of the sections are0 25X1
](centerline 25X1
measurements). The gridwork inside the sections slopes toward the center gridline with a
slope of
per gridline; the center gridline is F ]above the top of the railcar. 25X1
3. (TSR) An additional component was observed on the rail line leading into the four-bay construc-
tion hall on (Figure 4) and is probably associated with the reactor vault components. This 25X1
curved, open-ended component has heavy gridwork similar to that of the vault base sections and appears to be a
vault side section designed to fit around the vault base section to form part of the vaulted area for the reactor
(Figure 5). The outside width of this component is the inside width is The length of the 25X1
structural gridwork is the maximum internal length is and the maximum external length 25X1
is This component, together with an identical one and two flat components, would probably be 25X1
needed to form a complete reactor vault.
4. (TSR) Three different internal reactor-associated components for reactor vaults have been identi-
fied at.Severodvinsk Shipyard 402 Figures 6 through 12). These components have been named 25X1
for their probable position in the reactor vault as illustrated in Figure 5. The components are shown in Figures
6, 8, 9, and 11. Artist's conceptions of the components along with key dimensions are presented in Figures 7, 10,
and 12. The outer dimensions of the reactor foundation plate and the upper reactor framework are nearly
identical. The midsection spacer has only been observed on but the dimensions are compatible 25X1
with those of the other two pieces and fall within the accuracy statement.
5. (TSR) The only known nuclear submarine being constructed at Komsomolsk at this time is the V-III
nuclear-powered submarine (SSN). Probable reactor templates for these units have previously been observed in
the fabrication/open storage areas on the southeastern side of the yard. The submarine programs currently
underway at Severodvinsk include D-III nuclear-powered ballistic missile submarine (SSBN), Typhoon SSBN,
ALFA SSN, and a new probable nuclear-powered guided missile submarine (SSGN). The fact that these pieces
do not appear to be compatible with any previously identified submarine program suggests that they are
probably for new-generation reactors for one of several new classes of submarines under development, including
the Typhoon SSBN and probable SSGN at Severodvinsk, and a probable new class (type undetermined) at
Komsomolsk.
(TSR) All relevant KEYHOLE imagery acquired between
was used in the preparation of this report.
