2025:08 Carbon-14 in the marine environment of Ringhals nuclear power plant
at background levels resulting from natural production and atmospheric testing of nuclear weapons, which were mainly carried out during the 1950s and 1960s. C-14 is an important radionuclide from a radiation ... plants, reprocessing of spent nuclear fuel and storage of radioactive waste, etc. Unlike most other radionuclides (which are often metals), redistribution and accumulation in the marine ecosystems of C-14...

2024:18 Modelling Environmental Sensitization of Chromia Forming Nickel Base Alloys Toward Stress Corrosion Cracking in Light Water Reactors by Atomistic Simulations
been a longstanding issue both in pressurized and boiling water reactors. The specific environment in nuclear power applications consists of high temperatures and pressures that together with the effects of ... some of the applications. Thus, it is important to improve the understanding of the corrosion process and to gain insight regarding the effect of coolant composition on the chromia forming nickel-base alloys...

2024:17 Atomistic studies on the adsorption and desorption of radionuclides on fuel crud and system surfaces in Light Water Reactors
in the core during operation may accumulate on system surfaces such as the filter system or piping and contribute to the radiation field. Some ions that are prone to neutron capture often become trapped ... incorporated and released from the CRUD in order to increase radiation safety. Density functional theory (DFT) calculations have been used to gain a better understanding of CRUD formation and transformation...
