Bryan Black

VP of Business Development

As Vice President of Business Development at Deep Fission, Bryan Black brings nearly two decades of leadership across wholesale power markets, utility operations, regulatory compliance, and large-scale energy development. His career reflects direct responsibility for power plant operations, market strategy, and commercial execution within highly regulated electricity markets spanning multiple U.S. regions.

Bryan’s experience includes oversight of diversified generation fleets across coal, natural gas, wind, solar, and hydro assets, with accountability for NERC/FERC compliance, emissions compliance, and good utility practice standards. As Director of Market Operations and later Chief Operating Officer at UAMPS, he managed approximately 1,200 MW of load serving 50 municipal utilities across seven western states and oversaw roughly $350 million in annual electricity sales. His role included strategic growth initiatives, resource planning and optimization as well as new generation integration.

Earlier in his career, Bryan traded and dispatched wholesale power across every U.S. power market, including management of generation portfolios at Tenaska Power Services, a company that managed 60,000 MW at the time. He contributed to major commercial nuclear agreements, served large loads in Nevada and led a 100 MW solar/BESS request-for-proposal process for a large load user. Prior to joining Deep Fission, he started the interconnection process and market strategy for a proposed 600 MW small modular nuclear reactor project in Idaho. Later, as the co-founder and CEO of Nodal, he managed commercial relationships, permitting, and development efforts.

Bryan holds a Master of Management in Energy from Tulane University and a Bachelor of Arts from Brigham Young University. His background across regulated utilities, wholesale markets, and first-of-a-kind nuclear development brings a commercially grounded, system-level perspective to advancing next-generation nuclear power within competitive and compliance-driven energy markets.

Brett Siebert

Senior Thermal Hydraulics Engineer

With over thirty years of engineering leadership in nuclear reactor analysis and multi-physics simulation, Brett brings his submarine-nuclear power expertise to Deep Fission’s subsurface reactors.

He pioneered advanced thermal-hydraulics methods—deploying boiling-flow CFD codes and extending TRACE’s transient modeling capabilities to advanced reactor concepts—and wove together nuclear physics, thermal-hydraulics, structural mechanics, and materials performance into practical design tools.

Brett holds an M.S. in Aerospace Engineering from Penn State University and a B.S. from Boston University.

Alex Spire

Strategic Solutions Manager

As Strategic Solutions Manager at Deep Fission, Alex Spire operates at the intersection of regulatory strategy, capital formation, and operational execution. As the company’s first employee, he has played a foundational role in building institutional processes, coordinating cross-functional initiatives, and supporting high-stakes engagements with investors and federal stakeholders.

Alex has led complex, time-sensitive efforts requiring precision, discretion, and alignment across technical, financial, and legal teams. During Deep Fission’s APO-related due diligence process, he coordinated collaboration among external counsel, auditors, investment advisors, and internal leadership, fulfilling 192 distinct audit line items and building a comprehensive, regulator-ready due diligence catalog. This effort, completed within compressed timelines, contributed to a $30 million capital raise within 26 months of incorporation. He also played a central role in Deep Fission’s successful acceptance into the U.S. Department of Energy Reactor Pilot Program, authoring and editing a 50+ page application and collaborating closely with engineering leadership to develop cost-share modeling and programmatic strategy.

In parallel, Alex designed and implemented an AI-enabled regulatory and licensing documentation framework that accelerates the production of design-agnostic, regulator-ready materials. By developing internal doctrine and leading training across departments, he operationalized AI tools to increase document production speed by approximately eightfold while maintaining quality and compliance standards—an early example of disciplined AI integration within a nuclear startup.

Prior to joining Deep Fission, Alex worked in climate and nuclear policy, including roles at Ploughshares Fund and the Quincy Institute for Responsible Statecraft, where he focused on nuclear weapons policy and diplomacy. He holds an MBA from Georgetown University’s McDonough School of Business and brings a balanced approach that integrates policy fluency, operational rigor, and commercial awareness in advancing next-generation nuclear energy.
