Abstract
The contribution to hydrogen ingress from nuclear processes is evaluated. The processes investigated are: the production of protons and deuterons by the (n,p), (n,d), ({gamma},p), and ({gamma},d) reactions in Zr, Nb, and chemical impurities in the fuel channel materials; the implantation in the fuel channel of the high-energy protons and deuterons generated by the collisions of fast neutrons with hydrogen and deuterium in the cooling water; and, the implantation of the protons produced by the photo-disintegration of deuterium in the cooling water and the implantation of the protons produced by the photo-disintegration of deuterium. The total ingress over a 20-year time span from the nuclear sources is calculated to be less than 6 ppm by wt. The study indicates that impurities like nitrogen could generate high levels of hydrogen from N(n,p)C reaction if the impurity levels are not controlled.
