[en] A measurement program to obtain relative La-140 gamma ray intensities from irradiated fuel bundles and rods was conducted at the Hatch-1 Reactor during the refueling and maintenance outage at the end of the first fuel cycle. Of 106 bundles measured, 75 comprised a complete octant of the core and 35 were adjacent to partially inserted control blades. The report describes the measurement program and contains the gamma scan measurement data. The data are reported as relative La-140 intensities for discrete locations along the fuel axis. The data are further formatted into various displays to accentuate particular features of the core, such as controlled bundle shapes, core radial shapes, and bundle power asymmetries. Evaluation of the measurement uncertainties yields values of +-1.7% (1 sigma) for bundle nodal intensities and +-2.0% (1 sigma) for most of the single fuel rod intensities
