In this paper we present a calculation of the sensitivity of the CUORE detector to the monoenergetic 14.4 keV solar axions emitted by the M1 nuclear transition of {sup 57}Fe in the Sun and detected by inverse coherent Bragg-Primakoff conversion in single-crystal TeO{sub 2} bolometers. The expected counting rate is calculated using density functional theory for the electron charge density of TeO{sub 2} and realistic background and energy resolution of CUORE. Monte Carlo simulations for 5y × 741 kg=3705 kg y of exposure are analyzed using time correlation of individual events with the theoretical time-dependent counting rate. We find an expected model-independent limit on the product of the axion-photon coupling and the axion-nucleon coupling g{sub aγγ}g{sub aN}{sup eff} < 1.105 × 10{sup −16} /GeV for axion masses less than 500 eV with 95% confidence level.
