Current understanding of radiation-induced degradation in light water reactor structural materials

RADIATION-INDUCED DEGRADATION OF WATER POLLUTANTS--STATE OF THE ARTt

-The radiation-induced decomposition of biological resistant pollutants in drinking as well as in wastewater is briefly reviewed. First, some important units, definitions etc., radiation sources, as well as dose-depth curves in water as functions of the electron energy and 6°Co-y-rays are mentioned. Following is a schematical presentation of water radiolysis and of characteristics of primary fr...

Structural materials challenges for advanced reactor systems

Key technologies for advanced nuclear systems encompass high temperature structural materials, fast neutron resistant core materials, and specific reactor and power conversion technologies (intermediate heat exchanger, turbo-machinery, high temperature electrolytic or thermo-chemical water splitting processes, etc.). The main requirements for the materials to be used in these reactor systems ar...

Understanding Potential Induced Degradation

Potential Induced Degradation (PID) is an undesirable property of some solar modules. The factors that enable PID (voltage, heat and humidity) exist on all photovoltaic (PV) systems, but the effect does not occur on all or even most PV systems. According to Dr. Peter Hacke of the National Renewable Energy Laboratory (NREL), “All c-Si [crystalline silicon] modules have elements of reversible and...
