Who we serve

Built for every reactor on the horizon.

Whether you're certifying a first-of-a-kind microreactor or restarting a 1,200 MW BWR to feed an AI training cluster, APANTEC's modular instrumentation scales to your application — and our quality program scales to your regulator.

Advanced Reactors

Small Modular & Microreactors

Compact, fully integrated RMS that fit the SMR design philosophy: factory-built, safety-grade, and ready for serial deployment. We work alongside vendors and AE firms during licensing and FOAK construction.

Aligned withNuScale · X-energy · TerraPower · Kairos · Holtec · BWXT · Westinghouse AP300
Hyperscale Power

Reactor Recommissioning for Data Centers

Restart projects need RMS that's qualified for safety-grade duty and integrates with modern plant DCS. We refurbish legacy NRC and Canberra channels, supply form-fit replacements, and stand up DORIS for centralized telemetry.

Research

Universities & Research Reactors

From neutron monitoring at FRIB to area RMS for university research reactors, our channels are flexible enough for academic experimentation and rugged enough to run continuously for decades.

Installed atMichigan State FRIB · Jefferson Lab · BARC · Dalat (IAEA) · MIT-class research reactors
Emerging Markets

Fusion Pilot Plants

Tokamak-class neutron flux. Tritium handling. Activation of structural components. Fusion pilot plants need an instrumentation partner that already understands neutron and gamma metrology at scale.

Built for the next waveCommonwealth Fusion · Helion · TAE · Pacific Fusion · ITER suppliers
Healthcare & Industry

Medical Isotopes & PET Centers

Cyclotron and PET facility monitoring with the dynamic range to handle both ambient backgrounds and stack-level releases. Compliant documentation that satisfies state radiation control programs.

Mission-Critical

National Labs, Defense & Security

From DOE national labs to MRDIS systems screening containerized cargo at international seaports, APANTEC instruments operate in environments where reliability is non-negotiable.

Why APANTEC

One platform. Every channel. Decades of qualification.

The same modular instrument family scales from a single area monitor to a full plant — and every component is documented, qualified, and supported for the full plant lifetime.

Safety-grade by design

Qualified to 10CFR50 Appendix B and audited by NUPIC. Class 1E qualifications per IEEE-323, IEEE-344, and Regulatory Guide 1.97 — ready for the most demanding regulatory environments.

Modular & integrated

Standard detectors, DCUs, samplers, and the DORIS software platform interconnect over Ethernet (PoE optional) — purpose-built for the configure-don't-customize world of SMR deployment.

Plant-lifetime support

We refurbish legacy NRC and Canberra equipment, hold spares for the global installed base, and offer extended-warranty service contracts that outlast typical OEM commitments.

Modern integration

MODBUS, RS-485, and TCP/IP interfaces ship standard — drop our channels into existing plant DCS or pipe everything into DORIS for unified visualization and historian-grade archiving.

Detection that scales

From 10 nSv/h ambient backgrounds to 5×10⁷ R/h post-accident fields — our detector lineup spans seven orders of magnitude with traceable NIST calibration.

Engineered in the U.S.

Designed, manufactured, and supported from our Lansdale, PA facility — with international representation in Mumbai. Domestic supply chain matters when the federal nuclear reauthorizations land.

Product highlights

The instruments behind every channel.

A complete product line of detectors, display and control units, samplers, and software — all interoperating over standard interfaces.

Spotlight

Powering AI with a reactor that's been running since the 1970s.

The nuclear-to-data-center thesis only works if legacy plants come back online safely, on schedule, and within the regulatory envelope. That requires more than just a few new detectors — it requires an instrumentation partner who already supports the equipment installed on day one and can integrate seamlessly with new safety system designs.

APANTEC carries spare parts for NRC and Canberra channels going back four decades, refurbishes legacy electronics to factory condition, and provides form-fit-and-function replacements that drop into existing infrastructure without re-licensing the surrounding system.

  • Engineering studies of legacy RMS configurations and recommended spare-parts kits
  • Refurbishment to factory condition with one-year factory warranty
  • Form-fit electronic replacements compatible with original system designs
  • DORIS integration for unified telemetry across legacy and new equipment
