Description
Axial and radial measurements of spectrum index (ratio of various fission rates) were performed using 235U, 238U and 237Np fission chambers located inside a special fuel pin. This special designed fuel pin is hollowed in the centre, and allows the fission chambers to be inserted inside the fuel. A tight tube is fixed at the upper part of the pin and enables the connexion cable to leave the pool of the reactor. Radial traverses were investigated to analyze the shape of the fission rate in different energy ranges. A strong asymmetry of the distribution was detected and an interpretation of that effect is given. (author)
