TA-9 More Details

March 1998 4 4 TA and Facilities Descriptions Facility Hazard Categories
Table 4-5 identifies the facilities at TA-9 that fall into a facility hazard category because of the type
of operations performed in the facility. Nuclear Facility Hazard Categories
No facilities at TA-9 are categorized as nuclear facilities. Non-Nuclear Facility Hazard Categories Facilities Categorized L/ENS

Thirty-two of the 45 structures at TA-9 (Figure 4-7, Sheet 1)—magazines, lab buildings, and process
labs—are categorized L/ENS. Some of the laboratories are equipped with hoods, and some
hoods are specially equipped for handling radioactive materials. Building 21 contains offices, laboratories,
and space for storing chemicals. Six buildings (Buildings 22-27) are small, reinforcedconcrete
structures used to store small, frequently used samples. Building 32 contains two laboratories
and a mass spectrometer used to analyze gas samples. Its laboratories drain into an HE
sump outside the building. Ten buildings (Buildings 34, 35, 37, 38, 40, 42, 43, 45, 46, and 48)
are reinforced-concrete structures with process rooms and bays that have blow-out walls designed
to release pressure in the event of an explosion. Building 40 is partially underground to provide
extra protection in the event of an accidental explosion. Building 42 is located near the road
but is separated from the road by an earthen barricade. The remaining buildings are miscellaneous
storage buildings, shops, and shelters.
HE waste from the sump is pumped out and flash-burned at burn pads located at TA-16, and the
residues are disposed at Area J. Supernatant water from the sump is discharged to the environment. Facilities Categorized L/CHEM
Two buildings (Figure 4-7, Sheet 1), a gas storage building and a stock and equipment building
(Buildings 29 and 31), are categorized L/CHEM. Nonhazardous Facilities
The remaining buildings contain operations that are not considered to involve unusual hazards.
Building 20 is an office building.
