We have calculated unified photorecombination cross sections and independent-processes photorecombination cross sections for U{sup 90+} in the vicinity of the {ital KLL} resonances. For this case, where the radiative width of a level dominates the Auger width, we find relatively strong interference effects between the direct (radiative) and indirect (dielectronic) recombination processes. In particular, we find that the unified photorecombination cross section for the 1{ital s}{sup 2}+{ital e}{sup {minus}}{r arrow}1{ital s}{sup 2}2{ital s}+{ital h}{nu} line is suppressed by a factor of 2 in the presence of the 1{ital s}2{ital s}(1)2{ital p}(3/2) resonance. Overall, however, the {ital KLL} recombination cross section is reduced by only 2--3 %, at most.
