Overview
The VeryFuel is an Non Destructive Assay (NDA) tool for verification of modern fresh fuel assemblies. The VeryFuel has the capability to measure the 235U content per unit of length with unprecedented speed and much lower systematic uncertainty in presence of burnable poisons. The detectors and data analysis was developed by the IAEA and Member States Support Programs.
The VeryFuel utilises low-hazard liquid scintillation detectors and an integrated data acquisition system to measure coincident fast neutrons from induced nuclear fissions.
The standard geometric configuration fits the profile of the fuel assemblies for PWR and WWER1000 reactors.
CAEN SyS provided the VeryFuel to the International Atomic Energy Agency (IAEA) as the Fast Neutron Collar (FNCL) and its user requirements have been defined in the safeguards operational divisions.
The reduced coincidence gate and low accidental neutron coincidences allow the operator to employ high activity neutron source for active interrogation. Subsequently, measurement times for the same level of precision can be greatly reduced.
The VeryFuel comprises a detector assembly and a DAQ system with modular digital electronics, embedded PC and data processing software.
The detectors and data analysis was developed by the IAEA and Member States Support Programs.
The software allows the user to configure the data acquisition through an intuitive graphical user interface and shows the result of the real time data processing.
