Bound state in continuum (BIC) might appear in open quantum dots for variation of the dot's shape. By means of the equations of motion of Green functions we investigate effect of strong intradot Coulomb interactions on that phenomenon in the framework of impurity Anderson model. Equation that imaginary part of poles of the Green function equals to zero gives condition for BICs. As a result we show that Coulomb interactions replicate the single-electron BICs into two-electron ones.
