Abstract
"Zirconium alloys are used in heavy water-cooled reactors due to their low thermal neutron capture cross-section and good mechanical and corrosion properties. At the beginning of their operation, hydrogen was identified as an embrittlement agent. The source of the embrittlement was hydride precipitates that formed as platelets. Hydrides were associated with the cracks and the process was called Delayed Hydride Cracking – DHC. This research aims to develop a reproducible procedure concerning DHC KIH parameter measurements on Zirconium claddings, by using the Pin Loading Test (PLT) technique. Experimental activities including sample preparation, adding hydrogen, testing and results are presented in detail. "
期刊介绍：
Romanian Journal of Physics was first published in 1992 as a continuation of the former Revue Roumaine de Physique (ISSN: 0035-4090), a journal publishing physics and engineering scientific papers established 1956 with deep roots in the early history of the modern Romanian physics.
Romanian Journal of Physics is a journal of the Romanian Academy published by Editura Academiei Romane (eA). The journal has an international character intended for the publication of original physics contributions from various sub-fields including the following:
-Theoretical Physics & Applied Mathematics
-Nuclear Physics
-Solid State Physics & Materials Science
-Statistical Physics & Quantum Mechanics
-Optics
-Spectroscopy
-Plasma & Laser Physics
-(High Energy) Elementary Particles Physics
-Atomic and Molecular Physics
-Astrophysics
-Atmosphere (Environmental) & Earth Science
-Environmental Protection
