Nuclear Reactor Instrumentation

Nuclear Reactor Instrumentation Overview

Nuclear Reactor Instrumentation for the New Era of Nuclear

GE offers the complete line of in-core and ex-core sensors for boiling water reactors (BWRs). We also offer all of the components and equipment necessary to support our systems and detectors. With more than 50 years of experience in designing, manufacturing, installing and monitoring BWR detectors, GE has emerged as the technological leader in this industry.

Neutron Monitoring Instrumentation

Source & Intermediate Range Detectors (SRM/IRM)

GE is a technological leader in reactor startup instrumentation sensors.
Startup/Wide Range Detectors

GE designed its Reuter Stokes WRNM to perform the functions of both the SRM and IRM during reactor startup.
Dry Tube Assemblies

GE manufactures Reuter Stokes SRM/IRM, WRNM, LPRM and universal dry tubes for the boiling water reactor fleet.
Power Range Detectors (LPRM)
GE has more than 45 years of experience designing and manufacturing Reuter Stokes LPRM detectors.

Traversing In-Core Probes (TIPs)
GE offers two types of Reuter Stokes traversing in-core probes (TIPs): the gamma TIP and the neutron TIP.
Ex-core Fission Chambers
GE can design and manufacture fission chambers for many different types of applications, including PWRs, heavy water reactors and research reactors.
Moveable In-Core Detectors (MIC) PWR applications

GE offers the Reuter Stokes moveable in-core (MIC) sensor, which is used in pressurized water reactors to map the thermal neutron flux.

Water Chemistry

Electrochemical Potential Probes

Electro-chemically active elements dissolved in the coolant stream can cause inter-granular stress corrosion cracking in the reactor vessel and piping.
In Core ECP probes

Electro-chemically active elements dissolved in the coolant stream can cause inter-granular stress corrosion cracking in the reactor vessel and piping.

Mechanical Equipment

TIP/SRM/IRM Mechanical Drive Equipment

GE provides quality, technology-driven support equipment for its Reuter Stokes SRM and IRM detectors, including drive mounts, motor modules, flex shafts, drive tubes and shuttle tubes.
Undervessel Equipment

GE offers a variety of products that save time, eliminate personnel exposure and reduce costs during undervessel work on your Reuter Stokes SRM, IRM, LPRM and WRNM detectors.

RS Accessories

Cables & Connectors

GE has provided thousands of cables and connectors to the nuclear power industry. Whatever your cable and connector needs, we can custom-outfit your plant.
CRD Position Indicator

GE has made several design and manufacturing process improvements to the Reuter-Stokes position indicator probe (PIP) since assuming responsibility of the product line in 1999.
