TA-22 More Details

March 1998 9 5 TA and Facilities Descriptions
4.14.2.1 Facility Hazard Categories
Table 4-12 identifies the facilities at TA-22 that fall into a facility hazard category because of the
type of operations performed in the facility.
4.14.2.1.1 Nuclear Facility Hazard Categories
No buildings at TA-22 have been categorized as nuclear facilities.
4.14.2.1.2 Non-Nuclear Facility Hazard Categories
4.14.2.1.2.1 Buildings Categorized L/ENS

Twenty-five buildings at TA-22 have been categorized as L/ENS (Figure 4-14, Sheet 1).
4.14.2.1.2.1.1 Loading Building
The loading building (Building 1) is one of the buildings replaced by the Detonation Systems
Laboratory. It is currently unoccupied; however, HE contamination is still present.
4.14.2.1.2.1.2 Magazines
The magazines (Buildings 7, 9-12, 14-24, 35, and 96) are HE storage facilities.
March 1998 9 6 TA and Facilities Descriptions
4.14.2.1.2.1.3 Process Buildings
HE is used in Building 8. Building 25 is one of the buildings replaced by the Detonation Systems
Laboratory. It is currently unoccupied; however, HE contamination is still present.
4.14.2.1.2.1.4 Advanced Development Laboratory
The same kinds of explosives operations as those conducted at the Detonation Systems Laboratory
occur in the Advanced Development Laboratory (Building 34); however, the Advanced Development
Laboratory also conducts test firing operations, such as pulsed-high-voltage, hot-wire,
and laser firing. The laboratory is enclosed by a fence and interlocking gates so that opening any
interlocked gate or door safely disarms the high-voltage power distribution system. These precautions
prevent inadvertently initiating a test.
4.14.2.1.2.1.5 Storage Building
Building 69 is another small building used to store HE.
4.14.2.1.2.1.6 Detonation Systems Laboratory
The Detonation Systems Laboratory (Buildings 91 and 93) is a 43,000-ft2 (13,106-m2) structure
that provides research, development, and fabrication capabilities for detonation systems. This
structure consists of three connected buildings, one of which, Building 90, is an office building
(categorized as nonhazardous); Building 91 is a support building, and Building 93 is an HE fabrication
building connected to Building 91 by an enclosed corridor. A five-compartment explosives
storage magazine and a liquid solvent storage shed are located nearby.
In Building 93, bulk explosive powder is formed into detonator subassemblies and is incorporated
in final assemblies, which are then measured, inspected, and prepared for storage or test firing.
The area around the HE wing is enclosed by a fence with a locked gate, and access to the building
is limited to authorized personnel.
4.14.2.1.2.2 Building Categorized L/CHEM
Building 95 (Figure 4-14, Sheet 1) is a solvent storage shed.
4.14.2.2 Nonhazardous Facilities
The rest of the buildings at TA-22 are categorized as nonhazardous.
