Framework Service Contract covering the maintenance and improvement of existing tools and techniques used by Nuclear Inspectors of the European Commission
The framework contract to be concluded is mainly aimed at covering maintenance and improvement of existing tools and techniques used by nuclear inspectors of the European commission.
Contractor"s premises.
The directorate "Euratom safeguards" of DG energy in Luxembourg owns and runs a large number of unattended, automatic data acquisition systems (DAS) in nuclear facilities within the European Union.
A data acquisition system is highly modular; the components of a system include:
— Specific sensors (Neutron Monitors, Gamma detectors, Barcode readers...) which convert physical parameters (neutron and gamma radiation, light intensity, weight, fluid flow) into electrical signals.
— Signal conditioning components may be necessary if the signal from the device or the sensor is not suitable for the DAS hardware being used. The signal will be filtered or amplified in some cases.
— Analog-to-digital converters, which convert the conditioned sensor signals to digital values.
— Data acquisition devices (DAQ"s) are interfaces between the signal and a PC. It could be a module connected to the computer"s ports (parallel, serial, USB, etc.) or a card connected to slots in the motherboard.
— A sensor control platform allows users to configure maintain and troubleshoot DAQs and sensors remotely.
The system currently supports ~25 sensor modules from various manufacturers. New devices can be added as needed. The latest addition into the platform has been the integration of an electronic optical sealing system and a multiplicity shift register for neutron measurements.
The contract resulting from this call for tender will cover:
— Maintenance of the current operational data acquisition platform,
— Conceptualization, design and development of an improved data acquisition platform,
— Performance improvement and maintenance of the data review platform.
