NUCON | ADVERTORIAL FEATURE
Five Decades of Engineering Solutions in Nuclear Air Treatment
NUCON provides solutions combining system design, adsorption technology,
laboratory analysis, and field verification for nuclear utilities, government agencies, and industrial clients.
IN NUCLEAR FACILITIES, CONTROLLING airborne contaminants is essential for operational safety and environmental protection. For more than five decades, NUCON International has developed technologies that manage radioactive and hazardous airborne materials. Founded in 1972 in Columbus, Ohio, NUCON initially
focused on removing radioactive contaminants from air and gas streams in nuclear facilities. Today, NUCON operates as an employee-owned company, reinforcing its long- term commitment to quality, accountability, and customer partnership. Over time, this expertise expanded into engineering, laboratory, and field services supporting the nuclear, pharmaceutical and petrochemical industries.
Engineering Systems for Air Treatment NUCON designs and optimizes systems that capture and control airborne contaminants while protecting personnel and maintaining regulatory compliance. Examples include:
● Control room air treatment and habitability systems ● Gaseous radwaste filtration systems ● Reactor off-gas treatment systems ● Tritium control equipment ● Ventilation systems for contaminant capture ● Solvent Recovery
Because ventilation and filtration operate as integrated
processes, NUCON engineers analyze airflow, contaminant transport, and pressure relationships to ensure reliable system performance.
Adsorption Technology and Specialty Materials One of NUCON’s key strengths is the development and application of adsorption materials, particularly activated carbon products engineered for contaminant removal applications. Adsorption systems allow nuclear operators to capture contaminants at extremely low concentrations. NUCON develops specialty adsorbents formulated to target
compounds such as: ● Radioactive iodine species ● Mercury vapor ● Noble gases ● Acid gases and VOCs
When standard materials cannot meet performance
requirements, NUCON laboratories develop custom adsorbent formulations tailored to specific system conditions.
Laboratory Analysis and Performance Testing NUCON supports its engineering and materials work through specialized laboratory capabilities. Its facilities are licensed to handle radioactive materials, allowing engineers to evaluate filtration performance.
NUCON also participates in ASME and ASTM committees supporting nuclear air and gas treatment standards. For more than fifty years, NUCON has applied its expertise in engineering, adsorption technology, laboratory testing, and field verification to support the reliable operation of nuclear air treatment systems. As an employee-owned company, NUCON maintains a culture of accountability and long-term commitment to the industries and clients it serves. ■

● ASTM-compliant activated carbon testing ● Surface area and adsorption measurements ● Radioisotope tracer studies
These tools allow engineers to evaluate performance and adsorption behavior at low contaminant concentrations.
Field Inspection & Testing of Installed Systems Equally important to laboratory testing, system performance must also be verified in the field. NUCON’s Field Service department tests nuclear air treatment systems at facilities throughout the United States and internationally. Services include:
● Surveillance testing of nuclear air treatment systems (NATS)
● Acceptance testing of NATS ● Tracer gas in-leakage testing and pressure mapping
Testing is performed in accordance with ANSI/ASME N509,
ANSI/ASME N510, ASME AG-1 Section TA, and ASME N511, with personnel qualified under ASME NQA-1. To support these activities, NUCON also develops instrumentation for in- place testing of nuclear air treatment systems. Instruments such as the F-1000 HD™ Halide Detector and F-1000 DDF™ Aerosol Detector are used worldwide to perform leak testing and verify filtration system performance.
Engineered Filtration Hardware NUCON also manufactures specialized filtration components for nuclear air treatment systems. One example is the NUCON Type II reusable tray filtration system, designed to meet ASME AG-1 and N509 requirements. These trays provide consistent airflow and residence time, protect filtration media, and extend service life. Stainless-steel construction ensures reliable performance in nuclear applications.
Commitment to Quality and Industry Standards NUCON maintains a Quality Assurance program that meets
nuclear industry requirements, including: ● 10 CFR 50 Appendix B ● 10 CFR 21 responsibilities ● ANSI/ASME NQA-1 ● ANSI/ASME N45.2
