The flux pesking facter resulting from the use of a seamed fuel thimble in CP-5 was determined experimentally and by diffusion theory calculations. A comparison of the two methods indicates that an underestimation of the magnitude and sharpness of the flux peak is obtained from the diffusion calculations. Based on this comparison, a conservative calculation of the peaking effect which would result from the use of seamed fuel tubes in CP-5 indicates a maximum local power-peaking factor of 1.10 and a maximum fuel surface temperature 3 deg C above that obtained with extruded tubes for the same total reactor power and the same flow conditions.
