Our History

The road to success

For more than 30 years, AECOM and its heritage companies have partnered with the U.S. Department of Energy (DOE) to solve the nation's nuclear waste problem by helping to design, test and build a facility to dispose of transuranic, or TRU, waste. The waste began accumulating in the 1940's with the onset of the U.S. nuclear defense program. The Waste Isolation Pilot Plant began disposal operations in March 1999 and has been achieving success in the nation's national cleanup program.


WIPP Opens

Carved into an ancient deposit of salt 2,150 feet beneath the soil, WIPP is the only underground repository for radioactive materials in the country.


New Contract Awarded

AECOM along with BXW Technologies Inc. and AREVA Federal Services awarded contract to manage the WIPP site.



To date, WIPP has emplaced 91,000 m3 of transuranic waste in 170,000+ containers (fifty-five gallon drums, standard waste boxes and 10-drum overpacks.)

Our Leadership Team

Expertise and Reliability

Tammy Reynolds

Vice President and Deputy Project Manager

Tammy Reynolds, Deputy Recovery Project Manager for Nuclear Waste Partnership LLC, has 25 years of nuclear operations and project management leadership experience in the DOE complex. She joined the WIPP workforce in October 2011, after directing large, complex high-level waste projects at the Hanford 200 Area, the Idaho Cleanup Project at the Idaho Nuclear Technology and Engineering Center, and the Savannah River Site.

All have involved the analysis, characterization and certification of challenging waste forms and extensive interface with regulators. Reynolds brings in-depth institutional knowledge, best practices and lessons learned from these three large generator sites and understands the myriad technical and management challenges faced generally by all generator sites. She holds master and bachelor of science degrees in electrical engineering from the University of South Carolina.
