About the company
Sun Nuclear Corp.'s Medical Division manufactures and supplies specialized radiation therapy quality assurance equipment, diagnostic imaging phantoms, dosimetry systems, and associated software to federal healthcare agencies as a prime contractor competing on a full-and-open basis without set-aside designations. A subsidiary of Mirion Technologies headquartered in Melbourne, Florida, Sun Nuclear operates exclusively as a prime contractor across 573 federal awards spanning the past two decades, with no subcontract footprint.
The vendor's customer concentration is heavily weighted to the Department of Veterans Affairs, which accounts for the overwhelming majority of recent activity. The top five customers by award count—Veterans Integrated Service Network 10 (79 awards, $5.8 million), Veterans Integrated Service Network 8 (54 awards, $3.2 million), the Navy Bureau of Medicine and Surgery (37 awards, $1.4 million), Veterans Integrated Service Network 2 (32 awards, $2.2 million), and Veterans Integrated Service Network 4 (29 awards, $1.7 million)—represent 40 percent of all awards. When ranked by potential value, VISN 10 and VISN 8 remain the top two, but the National Cancer Institute enters the top five (18 awards, $3 million combined potential value), reflecting a secondary customer concentration in National Institutes of Health research support. The Defense Health Agency (25 awards, $1.9 million) and multiple other VA VISN networks complete the active customer base across 31 distinct federal agencies.
Sun Nuclear's product portfolio centers on radiation therapy quality assurance and diagnostic imaging systems. Typical awards include the Daily QA 4 Pro wireless system ($20.5 thousand to $124.6 thousand per unit), the SUNSCAN 3D water tank reservoir system ($159 thousand to $259 thousand with installation), the IC Profiler beam scanning system ($37 thousand to $192.6 thousand), MapCHECK and SRS MapCHECK intensity-modulated radiation therapy quality assurance devices ($17 thousand to $123 thousand), ArcCHECK 4D isotropic arc delivery systems ($22 thousand to $194 thousand), and associated dosimetry equipment, phantoms, and software platforms. Support contracts frequently include five-year base-plus-option structures for maintenance, software licensing, and technical support, valued from $35 thousand to over $540 thousand over the full term. A single indefinite delivery contract with VISN 10 (ceiling $89.4 thousand, February 2024 through January 2027) has generated three delivery orders for radiation therapy quality assurance software. The National Cancer Institute awarded a $87.4 thousand maintenance contract exercising option period four through August 2027. Recent awards to the Uniformed Services University of the Health Sciences ($173.8 thousand for a 3D water tank and software, July 2026) and the U.S. Air Force Life Cycle Management Center ($206.6 thousand for phantom radiology products, March 2025) represent non-VA federal healthcare customer diversification.
Award activity has remained relatively consistent across the past five years, with 2023 representing the peak at 37 awards and 2025–2026 holding steady at 25–29 awards per year. The vendor faces a recompete cliff of 35 awards (combined potential value $5.2 million) reaching ultimate completion within the next twenty-four months, representing a material recompete exposure concentrated in VA VISN maintenance and software support contracts. Combined potential value across the entire award population is $35.3 million, with $33 million (94 percent) already obligated, indicating a mature and stable revenue base. The awards are predominantly purchase orders and definitive contracts priced firm fixed price, with no awards classified as set-aside or reserved for small businesses, reflecting Sun Nuclear's competitive posture as an incumbent sole-source supplier of proprietary radiation therapy quality assurance equipment across federal healthcare networks.
