Comprehensive Summary

This open procurement by the European Commission’s DG ENER acquires two high-performance, portable gamma imaging spectrometers to reinforce Euratom nuclear safeguards inspections. The systems must combine coded-aperture and Compton imaging, deliver fine energy resolution (≤ 1% FWHM at 662 keV), and cover a broad energy range (≤ 50 keV to ≥ 3 MeV). They must localize a weak Cs‑137 source rapidly in low background, handle high dose-rate environments with alarms, and support robust, field-ready use with an IP67 enclosure, low weight (≤ 5 kg), rapid start-up, extended field of view, and flexible mounting. A mature software stack is required for real-time spectroscopy and imaging, automatic nuclide ID, advanced post-processing, dose display, and overlay of gamma activity on optical images. Delivery to Luxembourg is required within an 8-month contract window, with at least a two-year warranty and full conformity documentation, certificates, and manuals per unit. Tenders must strictly meet every minimum requirement; any deviation results in rejection. Award is on price only among compliant, eligible bids.

Eligibility is broad under EU procurement rules and GPA access, provided entities are not under EU restrictive measures. Applicants must show financial robustness (≥ €100,000 average turnover) and recent, relevant technical experience. Submission is electronic via the EU Funding & Tenders Portal by 13 April 2026. The package includes a detailed technical offer demonstrating compliance line-by-line, a signed financial bid using Annex 6, Declarations on Honour for all involved entities, and any required powers of attorney and commitment letters. The procurement ensures robust safeguards technology for nuclear material verification, enhancing inspectors’ capabilities to identify, localize, and map radioactive sources quickly and accurately across varied inspection environments.
