Sun Nuclear Corp.

Sun Nuclear Corp.'s Medical Division, a subsidiary of Mirion Technologies headquartered in Melbourne, Florida, manufactures and supplies radiation therapy quality assurance equipment, diagnostic imaging phantoms, dosimetry systems, and associated software to federal healthcare agencies as a prime contractor operating entirely under full-and-open competition with no set-aside designations. The company competes across 553 recent federal awards spanning the past two decades, with 92 percent of combined potential value obligated, generating $31 million in federal spending across a diverse portfolio of purchase orders, definitive contracts, and one active indefinite delivery vehicle.

Sun Nuclear's customer concentration is heavily weighted to the Department of Veterans Affairs, which accounts for the dominant share of both award volume and dollars. The top five customers by award count represent 41 percent of recent awards, led by VA Veterans Integrated Service Network 10 (77 awards, $5.9 million combined potential value), VA VISN 8 (50 awards, $3 million), and VA VISN 2 (32 awards, $2.2 million), with the Department of the Navy Bureau of Medicine and Surgery and Department of Defense Health Agency providing secondary volume. By dollar magnitude, VA VISN 10 and VA VISN 8 anchor the portfolio alongside the National Institutes of Health National Cancer Institute (18 awards, $3 million), which emerged as a second-tier customer on a per-award-value basis. Sun Nuclear holds a single-award indefinite delivery contract with VA VISN 10 valued at $89,445 running through January 2027, against which three task orders have been issued for software delivery and patient quality management systems.

Capability delivery spans equipment procurement, maintenance, and software licensing. Representative prime work includes a $541,800 definitive contract with VA VISN 22 for SunCheck Oncology equipment (August 2024); a $540,660 service contract with VA VISN 17 for full-service coverage of Sun Nuclear systems running through June 2027 (July 2022); a $429,030 purchase order from VA VISN 10 for a radiation detection quality management package (March 2022); a $404,280 maintenance services contract with VA VISN 16 for Sun Nuclear equipment at Jackson, Mississippi through September 2027 (October 2022); and recurring purchases across multiple VISNs for equipment including ArcCHECK systems, IC Profiler scanning systems, MapCHECK devices, Daily QA instruments, water phantoms, and dosimetry software. Defense Health Agency work includes a $229,505 hardware and software update contract for IC Profiler and MapCHECK systems (April 2026, running to April 2030) and a $211,683 maintenance and technical support contract for radiation therapy equipment at Bethesda, Maryland through September 2030 (October 2025). National Cancer Institute work encompasses maintenance services for government-owned dosimetry equipment and procurement of ArcCHECK and Daily QA equipment for quality assurance testing.

Activity has moderated year over year—25 awards in 2022 declining to 9 in 2026 (through early August)—with 23 awards valued at $5 million reaching ultimate completion inside the next twenty-four months and therefore subject to recompete. The company's product portfolio concentrates in medical device manufacturing (302 awards under NAICS 334519, Other Measuring and Controlling Device Manufacturing) and equipment repair and maintenance (47 awards under NAICS 811210). Federal procurement spend follows suit, with medical and surgical instruments and equipment forming the primary PSC category (228 awards) and maintenance and repair services the secondary category (79 awards). Sun Nuclear operates exclusively as a prime contractor; the source contains no sub-award activity.

Sun Nuclear's pricing posture across the portfolio reflects proprietary equipment dominance—numerous awards carry sole-source justifications under FAR 13.106-1 or 41 U.S.C. 3304(a)(1) citing Sun Nuclear's exclusive manufacturing capability and incumbent equipment status. The vendor competes on a full-and-open basis when competitive procurements are issued, but the recurring pattern of sole-source awards across multiple VISN networks indicates entrenched position in VA radiation therapy infrastructure. Contract values range from approximately $10,000 for individual components or modest software modules to over $600,000 for comprehensive multi-year service packages, with median individual award values in the $50,000 to $150,000 range. The company has established continuity of engagement through multiple-year task order sequences and option-year exercises on single-award IDVs and service contracts, particularly within VA VISN regions and at the Defense Health Agency.
