NEVADA TEST SITE

Environmental Management

The NNSA/NSO Environmental Management Mission was established to address the legacy of contamination at NTS. The Environmental Restoration Project is responsible for remediating contaminated sites and the Waste Management Project is responsible for managing and disposing radioactive waste. The Federal Facility Agreement and Consent Order (FFACO) between the State of Nevada, DOE, and DOD grouped projects as Corrective Action Units (CAUs), which are groupings of Corrective Action Sites (CASs) for the restoration project.

Notable CAUs include four facilities that were used for the Nuclear Rocket Development Program: Reactor Maintenance, Assembly, and Disassembly (R-MAD) in Area 25, Engine Maintenance, Assembly, and Disassembly (E-MAD) in Area 25, Test Cell "A" (TCA) in Area 25, Test Cell "C" (TCC) in Area 25 were designated corrective action units: CAU 113, CAU 114, CAU 115, and CAU 116 respectively. The Pluto Disassembly facility, used in Project Pluto, in Area 26 was constructed and used for the Ramjet Development Program. It was designated CAU 117. The Super Kukla Facility, which housed the Prompt Burst Reactor, in Area 27 was constructed and used for the Irradiation Tests Program. It was designated CAU 118. Junior Hot Cell and the Environmental Protection Agency Farm were also shutdown. R-MAD, Junior Hot Cell, and EPA Farm have been deactivated and decommissioned.
