In-house designed Nucleonic Instrumentation
The in-house product line of nucleonic instrumentation covers all neutron flux and gamma flux measurement requirements in Nuclear Power Plant cores qualified as IEEE Class 1E for safety critical applications.
The mentioned integral system is a line of electronic chains aimed at receiving signals from standardand wide-range (Campbellian mode) fission counters, compensated and non-compensated ionizationchambers, gamma chambers, and Self-Powered Neutron Detectors (SPND).
This is an evolutionary design from the lately 1970s, when necessary changes were made to eliminatedependency on critical components of early obsolescence probability and at the same time to add morefeatures commonly required at “up to date” instrumentation systems.
The standard product line includes:
- Source/Start-up channel (FC)
- Intermediate channel (IC)
- Power channel (IC or CIC)
- Wide Range log and linear auto-range channel (WRFC)
- Gamma measurement channel (IC)
- SPND channel (SPND)
