GENTILLY BLW BOOSTER ROD EXPERIMENTS IN THE ZED-2 REACTOR

Technical Report ·
OSTI ID:4765786
Measurements were performed in ZED-2 on simulated BLW 61-element boosters containing 5, 6.56 and 7.46 g of U{sup 235} per cm length. These boosters either replaced the central fuel assembly in a rod centred lattice or were located interstitially in an open centre lattice. The boosters' perturbing effects on the neutron density distribution and the epithermal index r {square-root}T{sub n}/T{sub O} were investigated. The fine structure and the reactivity worth of each booster were measured in the two lattices. The reactivity of the 5 g/cm booster was also measured as a function of radial position. (auth)
