A fundamental requisite to get a precise determination of light nuclide primordial abundances is the correct evaluation of the nuclear reaction rates of the BBN reaction network, as well as the corresponding uncertainties. In particular, for the primordial deuterium the most important nuclear inputs are the deuteron-deuteron transfer reactions, D(D,n)3He and D(D,p)3H, and the D(p,gamma)3He radiative capture. In this talk, I will review the current status in this field, with particular emphasis on the statistical method of analysis of experimental data to get the rates for deuterium synthesis.
