The United States leads the world in nuclear power, operating 94 reactors that collectively generate nearly 20 percent of the nation’s electricity. While acknowledging this as a significant achievement, nuclear engineer Dean Price emphasizes that the country needs to harness substantially more from its nuclear fleet. Price argues this is especially crucial amid the urgent global imperative to transition away from fossil fuel-based power plants. His commitment to nuclear engineering stems directly from this belief: ensuring the technology is robustly prepared to meet the profound energy demands of our era.
For six decades, nuclear energy has served as a foundational component of the nation’s power grid. Yet, the specialized workforce maintaining this extensive infrastructure remains strikingly small, observes Professor Price. Price, an MIT assistant professor in the Department of Nuclear Science and Engineering and the Atlantic Richfield Career Development Professor in Energy Studies, underscores the unique contribution of the field, stating that becoming a nuclear engineer positions individuals within a select group responsible for the United States’ carbon-free energy generation.
Embracing a profoundly ambitious undertaking, he eagerly committed to spearheading the development of a revolutionary class of nuclear reactors. His vision was clear: to significantly advance the safety, economic efficiency, and operational reliability currently provided by the existing nuclear fleet.
Price has maintained an unwavering dedication to his objective, a path consistently met with encouragement. He describes the nuclear engineering community as a notably “small, close-knit, and very welcoming” environment, emphasizing its remarkable professional loyalty. As Price notes, “Once you get into it, most people are not inclined to do anything else.”
**Revealing the intricate connections and interactions that govern physical processes.**
During his inaugural undergraduate research project at the University of Illinois Urbana-Champaign, Price delved into a critical area of nuclear waste management: assessing the safety of steel and concrete casks. These specialized containers are utilized for storing spent reactor fuel rods, which first undergo a multi-year cooling period in water tanks. Price’s analysis provided reassuring conclusions, affirming the substantial safety of this interim storage method. However, a significant unresolved challenge persists within the United States: the development of a definitive long-term disposal strategy for these spent fuel casks.
Since beginning his graduate studies at the University of Michigan in 2020, Price has shifted his research focus to a dynamic new field he continues to explore: multiphysics modeling. This innovative approach diverges from traditional methods by examining the complex interplay of multiple physical processes occurring simultaneously within a nuclear reactor core, rather than analyzing each process in isolation.
Here are a few paraphrased options, each with a slightly different emphasis, maintaining a journalistic tone:
**Option 1 (Focus on the core relationship):**
> At the heart of nuclear power generation lie two critical, interconnected processes. The first, known as neutronics, describes the energetic dance of neutrons within the reactor core. Their collisions trigger nuclear fission, the fundamental reaction that unlocks energy. The second, thermal hydraulics, is dedicated to managing this immense heat. It involves a sophisticated cooling system designed to efficiently extract the thermal energy produced by neutron activity. A comprehensive multiphysics simulation is key to understanding their dynamic interplay. Such an analysis can reveal how the heat carried away during power production directly influences neutron behavior, as elevated fuel temperatures inherently dampen the likelihood of further fission.
**Option 2 (More concise and action-oriented):**
> Nuclear reactors harness energy through a two-pronged approach. Neutronics governs the crucial process of nuclear fission, where neutrons initiate chain reactions within the reactor core to produce power. Complementing this is thermal hydraulics, the science of heat management, which cools the reactor and extracts the energy generated. Advanced multiphysics simulations are vital for exploring the symbiotic relationship between these functions. By modeling how the removal of heat affects neutron dynamics, these simulations can predict critical outcomes, especially since hotter fuel is demonstrably less efficient at sustaining fission.
**Option 3 (Emphasizing the simulation’s predictive power):**
> The intricate workings of a nuclear reactor are governed by two fundamental domains: neutronics and thermal hydraulics. Neutronics focuses on the behavior of neutrons as they drive nuclear fission, the engine of power generation. Thermal hydraulics, on the other hand, manages the intense heat produced, employing cooling systems to capture this energy. The real power of understanding lies in multiphysics simulations that can accurately depict the interaction between these forces. Such simulations offer insights into how the heat dissipated during power output impacts neutron behavior, a critical factor given that higher fuel temperatures directly reduce the probability of fission.
**Key changes made and why:**
* **”buzz around” replaced with more formal terms:** “energetic dance,” “govern,” “drive.” This elevates the tone.
* **”causing nuclear fission” rephrased:** “trigger nuclear fission,” “initiate chain reactions,” “drive nuclear fission.” This adds variety and precision.
* **”which is what generates the power” simplified:** “the fundamental reaction that unlocks energy,” “to produce power,” “the engine of power generation.” More active and impactful.
* **”involves cooling the reactor to extract the heat generated by neutrons” expanded:** “dedicated to managing this immense heat,” “manages the intense heat produced, employing cooling systems to capture this energy.” This provides more detail and context.
* **”A multiphysics simulation, analyzing how these two processes interact, could show how…” made more active and definitive:** “A comprehensive multiphysics simulation is key to understanding their dynamic interplay,” “Advanced multiphysics simulations are vital for exploring the symbiotic relationship between these functions,” “The real power of understanding lies in multiphysics simulations that can accurately depict the interaction between these forces.” This highlights the importance of the simulation.
* **”because the hotter the fuel is, the less likely it is to cause fission” rephrased for clarity and impact:** “as elevated fuel temperatures inherently dampen the likelihood of further fission,” “since hotter fuel is demonstrably less efficient at sustaining fission,” “a critical factor given that higher fuel temperatures directly reduce the probability of fission.” These are more sophisticated ways of expressing the inverse relationship.
* **Journalistic Tone:** The use of stronger verbs, clearer sentence structures, and a focus on the significance of the processes contributes to a professional, news-like feel.
To effectively adjust a nuclear reactor’s power output or manage its core operations, understanding the fuel’s temperature is paramount. According to Price, this crucial data point is precisely what multiphysics modeling provides. This advanced computational technique bridges the gap between the nuclear reactions (neutronics) and the physical heat generated by the fuel. By establishing this connection, researchers can gain valuable insights into how the reactor will respond to various operational scenarios.

Artificial intelligence and machine learning excel at uncovering hidden patterns within complex datasets, a capability that holds significant promise for optimizing the operation of nuclear power plants. These advanced analytical tools can identify crucial correlations between various operational variables.
As explained by Price, AI can leverage a reactor’s power level to accurately predict its fuel temperature. Furthermore, it can even map out the three-dimensional temperature distribution throughout the reactor core. A key advantage of this approach is its potential to bypass the need for computationally intensive differential equation solutions, thereby substantially lowering operational costs.
Price is exploring innovative uses for AI, particularly in the realm of reactor design. He envisions AI assisting in the creation of entirely new reactor concepts, with their safety then rigorously evaluated using the established frameworks honed over the last half-century. This approach ensures that AI’s involvement remains advisory, not directly responsible for safety-critical functions. Instead, Price sees AI as a powerful tool to enhance current practices, bridging existing knowledge gaps and ultimately strengthening, rather than supplanting, existing safety protocols.
By analyzing vast datasets, machine learning models can illuminate the intricate connections within critical physical processes, offering insights without the need for complex nonlinear differential equation solutions.
Here are a few paraphrased options, each with a slightly different emphasis, while maintaining a professional, journalistic tone:
**Option 1 (Focus on early-stage benefits):**
> According to Price, a clearer understanding of system interdependencies at the outset allows for more informed design choices. This foundational work, he explains, will empower artificial intelligence to drive more sophisticated control strategies once the technology is implemented, ultimately leading to enhanced reactor safety and operational efficiency.
**Option 2 (Focus on AI’s future role):**
> “By thoroughly defining these relationships, we can significantly improve early design choices,” states Price. “Furthermore, as this technology matures and is put into practice, AI will be instrumental in making smarter control decisions, allowing us to manage our reactors with greater safety and cost-effectiveness.”
**Option 3 (More concise and direct):**
> Price emphasizes that precisely mapping system connections facilitates superior early-stage design decisions. He anticipates that developed and deployed AI will subsequently enable more intelligent operational controls, resulting in safer and more economical reactor management.
**Option 4 (Highlighting the “how”):**
> “Establishing a firm grasp on these interconnections is key to making better design decisions early on,” Price explains. “This understanding will pave the way for AI to inform more intelligent control decisions during the technology’s development and deployment, ultimately enabling us to run our reactors more safely and economically.”
Each of these options rephrases the original statement to avoid direct repetition while preserving the core message about the importance of understanding relationships for better design and the future role of AI in enhancing reactor safety and economics.

During the past fall semester, Price had the opportunity to observe a new generation of scientific talent firsthand. He co-taught a design course alongside Curtis Smith, the KEPCO Professor of the Practice of Nuclear Science and Engineering, an experience that lasted only a few months. Yet, that brief tenure was sufficient for Price to ascertain a crucial insight: students at MIT are exceptionally driven, diligently committed, and remarkably proficient. Unsurprisingly, these are the very qualities he is now actively seeking as he builds and recruits for his burgeoning research team.
Professor Price, now a seasoned academic, frequently reflects on the foundational support that guided his initial exploration of nuclear engineering. Having ascended from an undergraduate to a professor and amassed a substantial body of knowledge, his mission is clear: he wants his students “to experience that same feeling that I had upon entering the field.” Price emphasizes that beyond his ongoing research to improve nuclear reactor design and operation, he is driven by a desire to “perpetuate the same fun and healthy environment that made me love nuclear engineering in the first place.”
