Planning and Communication Paves the Way for Cleanup of Nevada Clean Slate Sites
A focus on safety through planning and communication is driving cleanup activities at the Clean Slate sites on the Tonopah Test Range (TTR), just north of the Nevada National Security Site (NNSS). This summer, cleanup activities will be completed at the Clean Slate II site and work will begin at the Clean Slate III site. Remediation of both sites involves the excavation, packaging and disposal of contaminated soil and debris at the NNSS.
The Clean Slate sites were the location of experiments conducted in 1963 to test the safety of nuclear devices. Though these experiments did not result in a nuclear yield, they caused the dispersal of various surface contaminants, including plutonium and americium. Two previous cleanup campaigns occurred in the late 1990s and 2014 but excavation and removal of contaminated soil was delayed until future use of the sites and associated cleanup levels were determined.
Planning for this final phase of cleanup began in 2016 through close collaboration between the Department of Energy’s (DOE) Environmental Management (EM) Nevada Program; EM Nevada Program cleanup contractor, Navarro; State of Nevada Division of Environmental Protection (NDEP); the U.S. Air Force and Sandia National Laboratories (both conduct activities on the TTR); and the Nevada Site Specific Advisory Board (NSSAB).
Upon agreement of a path forward, the EM Nevada Program focused on informing local communities about upcoming fieldwork. Throughout May and June 2017, briefings were provided and questions answered at meetings in Goldfield, Tonopah, Pahrump, Beatty, and Las Vegas. “Our commitment to sharing information and listening to feedback supports the building of trust within our neighboring communities,” said Rob Boehlecke, EM Nevada Program Manager.
To broaden public awareness, a fact sheet was published on the NNSS website and hundreds of copies distributed to intergovernmental groups; the Timbisha Shoshone Tribe; and libraries, senior centers, community organizations, and post offices in Tonopah, Goldfield and Beatty – rural communities that waste shipments travel through to the NNSS.
While community engagement efforts were taking place, preparations were finalized for field activities with an emphasis on safety. After successfully demonstrating readiness, the skilled and experienced crew proceeded with excavation and packaging of contaminated soil in November 2017. The first shipment of waste to the NNSS occurred in mid-December after coordinating with Nye County Emergency Management and the Nevada Department of Transportation to obtain and share information on routing.
Throughout remediation, coordination with Sandia and the U.S. Air Force continued, along with updates to the public. This included two Community Conversations events held in Tonopah.
In addition to ongoing communications, the safety of field activities continued to be evaluated and enhanced. Several safety initiatives were implemented, such as relocating equipment and activities to reduce heavy equipment operation and lessen worker fatigue. Management also collaborated with field workers to address unexpected oversized concrete debris found during excavation.
As remediation wraps up at Clean Slate II with the completion of an anticipated 170 shipments by the end of June, the focus on safety, communication, and experience will be carried forward to Clean Slate III. This summer, workers will begin excavating, removing, and packaging approximately 7,500 cubic yards of soil and debris. The effort is expected to continue into 2019 and involve an estimated 450 shipments planned in multi-week campaigns. The success of both cleanup and disposal campaigns have and continue to hinge upon the team’s commitment to safety and open and frequent communications.

NNSS, Japan Share Knowledge, Experience at AMS Workshop
A Japanese delegation recently visited the NNSS’ Remote Sensing Laboratory (RSL) at Nellis Air Force Base in Las Vegas, Nev., to learn about aerial measuring technology for their own use.
At the request of the National Nuclear Security Administration (NNSA)’s Office of Nuclear Incident Policy and Cooperation, the Aerial Measuring System (AMS) program out of RSL-Nellis hosted a workshop for the Japanese delegation. The delegation included individuals from the country’s Cabinet Office, Nuclear Regulation Authority, the Japan Atomic Energy Agency, and the OYO Corporation. The goal of the workshop was to provide Japan with technical updates on AMS methodology and operational processes as they explore the possibility of creating a similar capability.
The three-day workshop started with a visit to RSL for a tour of the Consequence Management (CM), AMS and Aviation assets. In addition to several presentations by both the Japanese guests and RSL-Nellis staff, the delegation also had a unique opportunity to fly in an AMS helicopter so they could observe the AMS training methodology first-hand.
Both RSL-Nellis and the Japanese enjoyed the chance to share their experiences and learn more about their counterparts from another part of the world. The visit also enhanced the relationships previously forged during the 2011 Fukushima response, where AMS and CM assets provided crucial data to the Japanese during that time of crisis. NNSA and the NNSS expect to continue to strengthen their relationship with Japan and other countries through similar events.
NASA, NNSS, partners complete Kilopower experiment at NNSS
Demonstration proves nuclear fission system can provide space exploration power
NASA and the Department of Energy’s National Nuclear Security Administration (NNSA) have successfully demonstrated a new nuclear reactor power system that could enable long-duration crewed missions to the Moon, Mars and destinations beyond.
NASA announced the results of the demonstration, called the Kilopower Reactor Using Stirling Technology (KRUSTY) experiment, during a news conference May 2 at its Glenn Research Center in Cleveland. The Kilopower experiment was conducted at the NNSA’s Nevada National Security Site from November 2017 through March.
“Safe, efficient and plentiful energy will be the key to future robotic and human exploration,” said Jim Reuter, NASA’s acting associate administrator for the Space Technology Mission Directorate (STMD) in Washington. “I expect the Kilopower project to be an essential part of lunar and Mars power architectures as they evolve.”
Kilopower is a small, lightweight fission power system capable of providing up to 10 kilowatts of electrical power - enough to run several average households - continuously for at least 10 years. Four Kilopower units would provide enough power to establish an outpost.
According to Marc Gibson, lead Kilopower engineer at Glenn, the pioneering power system is ideal for the Moon, where power generation from sunlight is difficult because lunar nights are equivalent to 14 days on Earth.
“Kilopower gives us the ability to do much higher power missions, and to explore the shadowed craters of the Moon,” said Gibson. “When we start sending astronauts for long stays on the Moon and to other planets, that’s going to require a new class of power that we’ve never needed before.”
The prototype power system uses a solid, cast uranium-235 reactor core, about the size of a paper towel roll. Passive sodium heat pipes transfer reactor heat to high-efficiency Stirling engines, which convert the heat to electricity.
According to David Poston, the chief reactor designer at NNSA’s Los Alamos National Laboratory, the purpose of the recent experiment in Nevada was two-fold: to demonstrate that the system can create electricity with fission power, and to show the system is stable and safe no matter what environment it encounters.
“We threw everything we could at this reactor, in terms of nominal and off-normal operating scenarios, and KRUSTY passed with flying colors,” said Poston.
The Kilopower team conducted the experiment in four phases. The first two phases, conducted without power, confirmed that each component of the system behaved as expected. During the third phase, the team increased power to heat the core incrementally before moving on to the final phase. The experiment culminated with a 28-hour, full-power test that simulated a mission, including reactor startup, ramp to full power, steady operation and shutdown.
Throughout the experiment, the team simulated power reduction, failed engines and failed heat pipes, showing that the system could continue to operate and successfully handle multiple failures.
“We put the system through its paces,” said Gibson. “We understand the reactor very well, and this test proved that the system works the way we designed it to work. No matter what environment we expose it to, the reactor performs very well.”
The Kilopower project is developing mission concepts and performing additional risk reduction activities to prepare for a possible future flight demonstration. The project will remain a part of the STMD’s Game Changing Development program with the goal of transitioning to the Technology Demonstration Mission program in Fiscal Year 2020.
Such a demonstration could pave the way for future Kilopower systems that power human outposts on the Moon and Mars, including missions that rely on In-situ Resource Utilization to produce local propellants and other materials.
The Kilopower project is led by Glenn, in partnership with NASA’s Marshall Space Flight Center in Huntsville, Alabama, and NNSA, including its Los Alamos National Laboratory, Nevada National Security Site and Y-12 National Security Complex.

Deputy Secretary of Energy Dan Brouillette visits the NNSS
Deputy Secretary of Energy Dan Brouillette visited the Nevada National Security Site April 2-4. He was accompanied by Captain Nathan Martin and Chief of Staff Jim Colgary.
Deputy Secretary Brouillette began his visit by meeting with seven NNSS early career professionals for lunch in North Las Vegas at the National Nuclear Security Administration’s Nevada Field Office Nevada Support Facility.
During the lunch, Brouillette took the time to learn a bit about NNSS’ attending young professionals, asking each one in turn several questions about themselves, as well as what brought them here, first impressions when joining the NNSS and more. “What does it take to keep you here?” was a reoccurring question throughout the afternoon.
Several of the young professionals cited supporting the national security mission as a reason they enjoy their work.
“It’s an important mission,” Brouillette agreed. “I hope you’re very proud of that.”
After the lunch, the deputy secretary joined a group of NNSS representatives in traveling to the Site, where he spent the following day-and-a-half meeting with Site leadership and visiting several facilities important to the NNSS’ current mission (the Device Assembly Facility and the U1a Complex, to name a few), in addition to historic locations.
Brouillette concluded his visit Wednesday, April 4, by touring the NNSS’ Remote Sensing Laboratory – Nellis and meeting with key leaders.

For these firefighters, there will be rites of passage they will have to endure. I congratulate them and welcome them to our F&R family,” said Deputy Chief Castro at the ceremony.
Family members and friends pinned their badges on, followed by hugs and handshakes.
NNSS revegetation project using tribal recommendations in full swing
Revegetation of the historic 92-acre disposal area at the Nevada National Security Site (NNSS) using recommendations from the people native to the land is underway. The project began in 2016 when the Environmental Management (EM) Nevada Program asked the Consolidated Group of Tribes and Organizations (CGTO) for assistance after previous attempts at revegetating the land were unsuccessful. Now, the EM Nevada Program is moving forward with incorporating the wisdom and traditional ecological knowledge shared by the CGTO that have been passed down among tribal members for thousands of years.
Representatives from the CGTO formed a Tribal Revegetation Committee (TRC) to provide recommendations to the EM Nevada Program after careful study, research, cultural interactions with the land, and consultation with tribal elders. The recommendations provided by the TRC include various seeding and transplant methods utilizing test plots and continual tribal contact with the land as the plants grow. The TRC has recommended a three-year study of the area in order to ensure establishment of the plants, which is consistent with the standard time frame used in ecological studies.
The six CGTO members of the TRC represent three broad ethnic groups with cultural and historic ties to the NNSS and surrounding lands: Southern Paiute, Western Shoshone, and Owens Valley Paiute-Shoshone. Two members from each group are working on the project along with additional expertise from CGTO spokesperson Richard Arnold; ethnoecologist Dr. Jeremy Spoon of Portland State University’s Department of Anthropology; and ecologist Dr. Michael Clifford of Desert Research Institute.
Based on their initial recommendation, tribal representatives observed the first planting last fall.
The TRC expressed their commitment to working closely with the EM Nevada Program in helping to restore ecological and cultural balance to the land. “We are the voices of the land who speak of its importance and desire to maintain ecological balance in accordance to tribal traditions,” Arnold says. Arnold explains that tribal people have been on the land for thousands of years and witnessed many changes, including the separation of tribal people from the land where they were created. “When we are reunited, the land welcomes our return so the healing can begin,” Arnold says.
The project continues in 2018 with a planned spring planting. The TRC recommendations include regular monitoring by the CGTO representatives as well as other tribal members, including young adults. These young tribal members will be encouraged to assist in the project, to help pass on tribal ecological knowledge for generations to come.
For the EM Nevada Program, the project demonstrates a commitment to consider tribal perspectives and concerns when completing environmental management tasks. “The input of culturally affiliated tribes is invaluable to the EM Nevada Program as we carry out our mission to ensure the protection of the public and the environment from the effects of historic nuclear testing. The revegetation project is part of a continuing effort to incorporate tribal involvement in EM missions,” says Rob Boehlecke, program manager, EM Nevada Program.
