OS5400 Sentinel Digital Fuel Breakage Detection Spectrometer

OS5400 Sentinel Digital Fuel Breakage Detection Spectrometer

Product introduction           

This extremely robust and reliable system monitors the concentration of fission and activation products in the reactor system to detect degradation of fuel boundary integrity based on the activity levels of key isotopes and their relative abundances. The FINESS system is a good example of such a system.

• Monitor the concentration of fission and activation products in the primary coolant to detect fuel element failures as they occur

• Unparalleled stability and reliability even under varying count rates and temperatures

• Provides a graphical display of concentration levels

• Monitor user-defined alarm levels

• Automate QA checks based on own performance

• Includes powerful, flexible networking options

Key Components

• The core of Sentinel is DSPEC, which uses DSP

(digital signal processing) technology for gamma ray spectrometers. Sentinel offers unrivaled stability under varying count rates or temperatures, making it ideal for automated monitoring applications. Sentinel can run on a single PC or a network of PCs under Windows® 2000/XP. Expensive custom software, custom enclosure design and on-site system integration will no longer be an issue.

• Sentinel acquires spectra, tracks activity levels in user-defined regions of interest, automates calibration checks, monitors alarm levels, stores data, and automates quality assurance procedures that check source data.

All activities can be performed locally or remotely from a PC with GammaVision software.

Structure

The detector cabinet contains the shield assembly, liquid nitrogen supply system, inspection source and a 25 mm diameter GLP planar germanium radiation detector that provides excellent energy resolution at low to medium energies. The selected forced feedback preamplifier is suitable for the expected high count rate. The detector has a robust ion-implantation front interface that eliminates X-ray spectral interference inherent in less reliable metal interfaces. The detector is surrounded by a lead shield assembly with detector collimator. The shield assembly is hinged and the detector is mounted on a sliding drawer for easy removal from the shield and detector cabinet.
