Supporting thermal-hydraulic test loops, hardware-in-the-loop systems, component qualification rigs, and digital twin validation environments used in advanced reactor programs.
Advanced reactor development programs depend on extensive experimental validation. Thermal-hydraulic loops, hardware-in-the-loop environments, component test facilities, and digital twin validation systems require synchronized measurement across large experimental infrastructures.
These experimental facilities support qualification, validation, and verification activities required throughout reactor design, licensing, and demonstration programs.

Large Sensor NetworksReactor test loops often require hundreds or thousands of sensors measuring temperature, pressure, vibration, strain, and neutron flux. |
 |
Harsh Industrial ConditionsInstrumentation must tolerate electrical noise, mechanical vibration, and temperature extremes found in experimental facilities. |
 |
Synchronized MeasurementsDistributed acquisition systems must maintain deterministic timing across multiple measurement nodes. |
Distributed DAQ systems place acquisition hardware close to sensors and connect nodes through synchronized networks using PTP and TSN across large experimental reactor facilities.
Instrumentation hardware used in these environments must tolerate electromagnetic interference, mechanical vibration, temperature variation, and electrical noise typical of large experimental test facilities. The architecture shown illustrates how distributed UEI measurement nodes can be synchronized across a TSN/PTP network to support large experimental reactor programs.
Advanced reactor development programs require instrumentation across multiple engineering domains. Distributed data acquisition systems support measurements throughout the reactor development lifecycle.
