Standardization Activities of the Euratom Neutron Radiography Working Group

In 1979 a working group on neutron radiography was formed at Euratom. The purpose of this group is the standardization of neutron radiographic methods in the field of nuclear fuel.

Activities of this Neutron Radiography Working Group are revised. Classification of defects revealed by neutron radiography is illustrated in a special atlas. Beam purity and sensitivity indicators are tested together with a special calibration fuel
pin.

All the Euratom neutron radiography centers will perform comparative neutron radiography with those items. The measuring results obtained, using various measuring apparatus, will form the basis to formulate conclusions about the best measuring methods and instruments to be used in that field.

Besides the atlas of neutron radiographic findings in light water reactor fuel, the Euratom Neutron Radiography Working Group has published a neutron radiography handbook in which the neutron radiography installations in the European Community are also described.
