Estimation of neutron fluence distribution within German PWR components for decommissioning studies [PDF]

EPJ Web of Conferences
On 15 April 2023, the last German NPPs were shut down. The final shutdown is followed by a post-operational phase in which measures can be carried out to prepare for the NPPs dismantling and decommissioning.

A Critical Review of Radiolysis Issues in Water-Cooled Fission and Fusion Reactors: Part II, Prediction of Corrosion Damage in Operating Reactors

Corrosion and Materials Degradation, 2022
The radiolysis of water is a significant cause of corrosion damage in the primary heat transport systems (PHTSs) of water-cooled, fission nuclear power reactors (BWRs, PWRs, and CANDUs) and is projected to be a significant factor in the evolution of ...

Achieving Net‐Zero in the Electricity Sector in China by 2050 Considering Environmental and Economic Objectives

Advanced Sustainable Systems, Volume 10, Issue 3, March 2026.
China's pathways to net‐zero electricity by 2050 are evaluated using life cycle environmental and economic assessment across six scenarios. Results show that a renewables‐only grid offers the best overall environmental performance and lowest cost, but increases burdens on metal depletion, land use, and ecotoxicity.

Characterization of Fuel Rods Supported by Dimple‐Less Spacer Grids and Subjected to Nonlinear Vibrations

International Journal of Mechanical System Dynamics, Volume 6, Issue 1, Page 3-21, March 2026.
ABSTRACT An experimental campaign was undertaken to demonstrate the applicability of the Bouc–Wen hysteretic model to describe the hysteretic system of the recent Framatome dimple‐less spacer grid design for Pressurized Water Reactors. The experimental setup subjected a reduced‐length fuel rod, supported at both ends by dimple‐less grids, to forced ...
