The changes in primordial nucleosynthesis resulting from small corrections to rates for weak processes that connect neutrons and protons are discussed. The weak rates are corrected by improved treatment of Coulomb and radiative corrections, and by inclusion of plasma effects. The calculations lead to a systematic decrease in the predicted /sup 4/He abundance of about ..delta..Y = 0.0025. The relative changes in other primoridal abundances are also 1 to 2%.
