Generation of MeV -energy protons in WWER reactor core

The spectrum of fast protons, generated by fast neutrons of WWER-1000 reactor core in water, has been calculated using the Monte Carlo method. The main mechanism of fast proton generation in the moderator is found to be elastic scattering of fast neutrons on hydrogen nuclei. Fast protons with mean...

Zusammenfassung:The spectrum of fast protons, generated by fast neutrons of WWER-1000 reactor core in water, has been calculated using the Monte Carlo method. The main mechanism of fast proton generation in the moderator is found to be elastic scattering of fast neutrons on hydrogen nuclei. Fast protons with mean energy 1 MeV flow towards the surface of cladding material at flux density 0.1 µA/cm2 . The process of hydrogen implantation into zirconium cladding is discussed in the article. Proton range distribution profile in cladding material is calculated. The role of this mechanism in the hydrogenation of zirconium under reactor irradiation is discussed.
