Los Alamos National Laboratory Transuranic Liquid Waste (TLW) Facility

About the Project

The Los Alamos National Laboratory (LANL) Transuranic (TRU) Liquid Waste Treatment Facility is a newly constructed nuclear treatment facility located within Technical Area 50 (TA-50), home to LANL’s Radioactive Liquid Waste Treatment Facility in continuous operation since 1963.

 

The project presented significant site challenges, including a steeply sloping, constricted footprint with multiple adjacent facilities required to remain fully operational and accessible to delivery and emergency vehicles throughout all phases of construction.

 

Designed, permitted, constructed and commissioned as a Hazard Category 3 (HC-3) Nuclear Facility, the structure includes a main level, mezzanine and below-grade effluent pits with cast-in-place concrete foundations and a precast concrete wall and roof system. The facility houses advanced treatment systems designed to process transuranic liquid waste to meet Waste Acceptance Criteria (WAC) for transfer into the Low-Level Waste (LLW) facility — a critical component of LANL’s radioactive waste management mission.

 

Our scope encompassed full procurement, installation, commissioning, testing and turnover of a code-compliant, NQA-1 facility delivered fully operational to TA-50 Facility Operations.
