Abstract

In order to evaluate crack propagation rate for irradiation assisted stress corrosion cracking (IASCC) of stainless steel, accurate estimation of theconcentrations of radiolytic species in the crack tip water is important. These concentrations are affected by energy deposition in the crack tip water. Concentrations were determined by measurements with thin thermo luminescence dosimeters (TLDs) and calculations based on a Monte Carlo method. Themeasured and the calculated results confirmed that the energy deposition rate in the crack tip water was larger than that in the bulk water. This wascaused by higher back-scattered radiation from the surrounding steel. The energy absorption of the water in the crevice with a 1 mum width was 1.3 times as high as that in the bulk water.
