Pressurized Water Reactor (PWR) Instrumentation

Pressurized Water Reactor (PWR) Instrumentation

Work with a world leader in fission chamber design and manufacture.


Neutron Flux Monitoring Solutions Built for Reliability and Value, Based on Decades of Experience

Reuter-Stokes engineers have been designing nuclear instrumentation for more than 50 years, including decades of experience with fission chambers. Our ex-core fission chambers and movable in-core (MIC) sensors deliver:

  • Reliability: With hundreds of fission chambers installed in PWR plants around the world, our products have a record of excellent operational performance and precision, even in the harshest environments.
  • Customizability: We offer safety-related guarded and unguarded fission chambers, along with electrical connectors and mineral-insulated signal transmission cables (coaxial and triaxial). We can customize our catalog to suit your specific needs.
  • Value now and over the long term: We offer industry-leading technical support in addition to rapid order-to-delivery times.
