To discharge of its responsibilities under Chapter VII of the EURATOM Treaty, the European  Commission uses measurement systems in nuclear installations across the European Union.  Passive Gamma Emission Tomography Systems will be used for verification of spent fuel  assemblies from Light-Water Reactors.  The communication language between the Commission and the awarded contractor is English.  2.2.1  The Euratom Safeguards Directorate (DG ENER-E) of the European Commission seeks to  procure the Contractor’s services for manufacturing, assembling and delivering Passive Gamma  Emission Tomography Systems (hereinafter referred to as “PGET”) to be used for verification of  spent fuel assemblies from Light-Water Reactors. The PGET shall be capable of operating  underwater (at a depth of at least 10m), to be used to examine a Trans axial region of a spent-fuel  assembly (minimum 2-year cooling time) and create a tomographic slice of the gamma-ray activity  in the region under inspection. In addition, the PGET shall be capable of measuring gross neutron  count rate and performing medium resolution gamma-ray spectroscopy.  A prototype PGET has been developed by the International Atomic Energy Agency (from now on  IAEA) and undergone extensive testing during the first quarter of 2017. The PGET shall be built as  per the design documentation listed in Annexes A, B, and C.  The IAEA owns the full intellectual property right of the hardware and software and has agreed to  allow Euratom to use the design documentation for procurement purposes. 2.2.2  In addition, DG ENER-E seeks to procure services related to updates to the PGET hardware  and software and repair of the units. These services are detailed in Section 2.4 below.
