Water Radiolysis in PWR Coolant

Stub — document the radiolytic decomposition of water under neutron, gamma, and alpha irradiation in pressurised-water-reactor primary circuits.

Key Topics

• G-values (primary yields) for gamma, neutron, and alpha radiation
• Radiolysis species: e⁻(aq), H, OH, HO₂, H₂O₂, O₂, H₂
• Reaction kinetics (R37 and R39 sets)
• Diffusion coefficients for liquid and vapour phases
• Activity coefficients and water activity models
• Liquid–vapour partitioning (Henry’s law, distribution coefficients)
