ABACC, CNEN and IAEA test the Fast Neutron Collar (FNCL) system in a Brazilian plant

In October ABACC received an invitation of CNEN to participate in the Fast Neutron Coincidence Collar (FNCL) field test at the Fuel Element Plant – FNC – Reconversion and Pastilles / Components and Assembly. This equipment is intended to allow the independent verification of the mass of U-235 in combustible elements containing Gadolinium.

This test was proposed by the IAEA to CNEN under the Brazil Support Program of the Department of Safeguards and it will contribute to the future qualification of the FNCL during IAEA/ABACC safeguards inspections at the nuclear fuel manufacturing plant.
