Atomic Show #347 – Dr. Jeff Waksman, Project Pele and Project Janus

The U.S. military has a strong and growing interest in using small and micro nuclear reactors as a means of reducing logistics challenges and improving operational resilience. They like nuclear reactors for their ability to operate independently of the grid for years without needing any new fuel. Almost as important is their ability to be designed to retain byproducts and reduce heat signatures for improved stealth.

Dr. Jeff Waksman Is the U.S. Army’s go-to guy for pioneering nuclear energy projects. Though no military-related project can be completed by a single person, program success often rests on the effective leadership provided by a singularly skilled leader who combines organization, inspiration and deep knowledge of how to get things done in a purposely hierarchical system.

Before his current role for the Army, Waksman led Project Pele – the military’s first micro-reactor project in 50+ years – for the Department of Defense’s Strategic Capabilities Office. He did well enough at that assignment to have been selected to lead a more expansive program to finally deliver nuclear fission capabilities to bases and units that need clean, reliable power that comes with a low logistics burden.

Fission’s characteristics are nothing new and the military’s interest dates to the earliest days of nuclear energy. The political, environmental and strategic situation has changed enough in the 50 years since the Army’s Nuclear Power development program was effectively cancelled to stimulate new efforts to address the economic and technical challenges that were never solved during the 1960s and 70s.

Waksman’s current role has the mouthful title of Principal Deputy Assistant Secretary of the Army (PDASA) for Installations, Energy and Environment (IE&E). Though only one of his responsibilities, he is the Army’s point person for a subsequent reactor development program called Project Janus.

Dr. Waksman joined me on Atomic Show #347 to discuss the lessons taught by Project Pele and to provide insights on how those lessons are being incorporated into subsequent programs, both civilian and military. We covered a variety of topics, including:

• Reasons why he was picked to lead Project Pele
• Direction provided to the Department of Defense’s Strategic Capabilities Office regarding program outcomes
• Focus on building systems that work in the real world instead of just more models
• Challenges of fitting inside tightly constrained boundaries (C-17 transport plane)
• Limiting components – not surprisingly, it was the heat exchanger that transferred reactor heat from the coolant gas to the power conversion system
• Importance of balance of plant compared to reactor
• Streamlining Department of Energy approval process
• Economic value of competition
• Economic trade-offs with the potential to make TRISO a more economic fuel than other options
• Project Pele’s influence on Reactor Pilot Program
• Project Janus goals and status
• Stretch goal timeline that includes the first operating reactor supplying a military base by the end of 2028
• Expansion of the project beyond the Army to the Air Force and possibly the Navy
• Unquantified description of the possible magnitude of military reactor program
• Desire for military reactor program to stimulate a larger commercial reactor market

I learned a lot from the show. Dr. Waksman shares valuable experience, including ways to avoid some of the bruises that came with leading the first-of-a-kind project for a modern transportable nuclear reactor and the U.S.’s first nuclear project development project in decades. I hope this show will influence those who follow so that they can make their own mistakes instead of repeating those that have already been made and documented.
