TA-46 More Details
March 1998 1 5 1 TA and Facilities Descriptions
4.24.2.1 Facility Hazard Categories
Table 4-22 identifies the facilities at TA-46 that fall into a facility hazard category because of the
type of operations performed in the facility.
4.24.2.1.1 Nuclear Facility Hazard Categories
No buildings at TA-46 are categorized as nuclear facilities.
4.24.2.1.2 Non-Nuclear Facility Hazard Categories
4.24.2.1.2.1 Building Categorized M/CHEM
The Chlorine Storage Building (Building 340, Figure 4-24, Sheet 1), part of the Sanitary Wastewater
Treatment Facility, is the only building at TA-46 categorized M/CHEM.
The Sanitary Wastewater Treatment Facility is located in a canyon in TA-46. Because it is isolated
from other Laboratory facilities, it poses little to no hazard to personnel. The facility uses a chlorine
gas process (widely used in the public sector) to disinfect plant effluents before releasing them into
a holding pond. The process uses quantities of chlorine that exceed Occupational Safety and
Health Administration threshold quantities; no other facility at the Laboratory uses this amount of
chlorine. Although these quantities are significant, the process is a proven technology that incorporates
a state-of-the art, fail-safe process. The effluent-chlorinating system is equipped with influent
and effluent chlorinators, chlorinators for water to be recycled, standby chlorinators, cylinder-
mounted regulators, and stored cylinders of chlorine. The system contains various fail-safe
leak detectors, breathing apparatus, and chlorine cylinder emergency repair kits.
At the time that this document was being prepared, plans were being implemented to replace the
chlorine gas process with a new water disinfection process that does not use gaseous chlorine.
This change will eliminate the potential for accidental release of large quantities of chlorine.
4.24.2.1.2.2 Building Categorized L/CHEM
Building 324 (Figure 4-24, Sheet 1) is a transportainer used to store uranium hexafluoride.

4.24.2.1.2.3 Buildings Categorized L/ENS
4.24.2.1.2.3.1 Laboratory/Office Building
Building 24 (Figure 4-24, Sheet 1) is used for experimental work involving lasers and UF6.
4.24.2.1.2.3.2 Electronics Laboratory
The Electronics Laboratory, also called the Hydraulics Laboratory (Building 30, Figure 4-24,
Sheet 1), is used for experimental work involving lasers.
4.24.2.1.2.3.3 Test Building #2
Test Building #2 (Building 31, Figure 4-24, Sheet 1) is used for experimental work involving
lasers.
4.24.2.1.2.3.4 Aerochemistry/Diagnostics Building
The Aerochemistry/Diagnostics Building, also called the Laser Isotope Separation Building
(Building 41, Figure 4-24, Sheet 1), is used for experimental work involving lasers.
4.24.2.1.2.3.5 Laser Laboratory
The Laser Laboratory (Building 76, Figure 4-24, Sheet 1) is used for experimental work involving
lasers.
4.24.2.1.2.3.6 Physical Chemistry Laboratory
The Physical Chemistry Laboratory, also called the Applied Photochemistry Building (Building
154, Figure 4-24, Sheet 1), consists of a 5,000-ft2 (1,524-m2), prefabricated metal structure primarily
used for conducting large-scale photochemical experiments. The experiments performed
at this facility involve some hazardous operations and high-powered gas laser energy sources in
which toxic and/or corrosive gases are used. High-voltage hazards also are present. Small quantities
of high explosives have been used in this facility.
4.24.2.1.2.3.7 Laser-Induced-Chemistry Laboratory
The Laser-Induced-Chemistry Laboratory (Building 158, Figure 4-24, Sheet 1) is used for experimental
work involving lasers.
4.24.2.1.2.3.8 Chemistry/Laser Laboratory
The Chemistry/Laser Laboratory, also called the Fourier Transform Spectrometer Facility (Building
200, Figure 4-24, Sheet 1), has an area of 3,340 ft2 (1,018 m2) and contains a small laboratory devoted
to handling tiny quantities of radioactive materials used for spectroscopic study of atoms
and molecules, applied photochemistry, and photophysics. Although Building 200 is the primary
location of these functions, several other buildings at TA-46 also accommodate some of these
functions.
4.24.2.1.2.3.9 Analytical Chemistry Building
The Analytical Chemistry Building (Building 250, Figure 4-24, Sheet 1) is used for experimental
work involving lasers.
March 1998 1 5 3 TA and Facilities Descriptions
4.24.2.1.2.4 Buildings Categorized L/RAD
4.24.2.1.2.4.1 Accelerator Vault Building
The Accelerator Vault Building (Building 161, Figure 4-24, Sheet 1) is used for experimental work
involving an accelerator and lasers.
4.24.2.1.2.4.2 Free-Electron Laser Laboratory
The Free-Electron Laser Laboratory (Building 208, Figure 4-24, Sheet 1) is used for experimental
work involving a radiofrequency generator (x-rays).
4.24.2.2 Nonhazardous Facilities
One hundred fifteen other buildings at TA-46 are categorized as nonhazardous. These facilities
house administrative, technical, general storage, experimental science, and physical support
functions.
