Robert Mariani

Robert Mariani serves as a key procurement lead within the Battelle Energy Alliance, operating under the U.S. Department of Energy, where he oversees acquisitions critical to advancing nuclear energy innovation and national security infrastructure. His responsibilities include managing the full lifecycle of contracts for specialized nuclear systems, including reactor instrumentation, safety-critical control systems, and advanced scientific equipment essential to next-generation reactor development. Mariani’s work directly supports the agency’s mission to enable licensing, deployment, and operational readiness of advanced nuclear technologies, ensuring compliance with stringent federal procurement standards and technical specifications for nuclear-grade components. His contractor relationships are primarily with highly specialized engineering firms and Tier-1 nuclear technology providers capable of delivering proprietary instrumentation, radiation-hardened electronics, and licensed reactor simulation software. These vendors typically possess DOE nuclear facility access, NRC licensing experience, and ISO 9001/ASME NQA-1 certifications. Mariani consistently engages with a select pool of qualified contractors with proven track records in nuclear-grade systems integration, emphasizing technical rigor, supply chain traceability, and regulatory compliance over cost alone. Mariani’s procurement portfolio reflects a 100% non-set-aside approach, indicating a focus on mission-critical capabilities that require specialized expertise not typically available through small business channels. While socioeconomic set-asides are not utilized, this reflects the technical exclusivity and security requirements of nuclear infrastructure acquisitions rather than a lack of small business engagement elsewhere in the agency. His primary NAICS focus is 221113 (Nuclear Electric Power Generation), with acquisitions centered on reactor safety systems, neutron detection arrays, thermal-hydraulic monitoring equipment, and fuel cycle instrumentation. Mariani’s domain expertise lies in procuring high-integrity systems for advanced reactor prototypes, including small modular reactors and research test facilities, requiring deep technical understanding of nuclear regulatory frameworks and defense-in-depth engineering principles.
