Abstract

1,248,030. Fuel elements. EUROPEAN ATOMIC ENERGY COMMUNITY. 23 July, 1970 [28 July, 1969], No. 35809/70. Heading G6C. The fissile content of nuclear fuel elements is measured by removing the elements from the reactor, storing the elements for an interval until the slow neutrons are emitted, irradiating the elements with the reactor neutron flux and then detecting the neutrons emitted which provides a measure of the fissile material content. Fuel element spheres from the core 1, are moved into the tube 3 for 15 minutes, where slow neutron emission occurs and then pass into the shield 4 where they are exposed to reactor neutron irradiation at 5. The neutron spectrum may be selected by filters. After a further period, the elements pass into the neutron detector 6 where the fissile content is estimated.
