“…Moreover, nuclear energy plays a proactive role in addressing global climate change, and its robust development aligns with the trend in world energy utilization, holding significant importance [ 2 , 3 , 4 ]. Nonetheless, while nuclear power effectively contributes to the transition toward cleaner and lower-carbon energy, it inherently carries a higher degree of risk [ 5 ]. Hence, ensuring the safe operation of nuclear power systems becomes critically important, as the safety of nuclear power largely depends on the safe functioning of its equipment.…”

This study subjected nuclear-grade 20# pipeline steel to cyclic freeze–thaw ice plugging tests, simulating the plastic deformation experienced by pipes during ice plug removal procedures. Subsequently, the dislocation morphology and mechanical properties of the specimens post cyclic ice plugging were examined. The cyclic ice plugging process led to an increase in the dislocation density within the specimens. After 20 and 40 cycles of ice plugging, the internal dislocation structures evolved from individual dislocation lines and dislocation tangles to high-density dislocation walls and dislocation cells. These high-density dislocation walls and cells hindered dislocation motion, giving rise to strain hardening phenomena, thereby resulting in increased strength and hardness of the specimens with an increasing number of ice plugging cycles. In addition, a large stress field was generated around the dislocation buildup, which reduced the pipe material’s plastic toughness. The findings elucidate the effects of cyclic ice plugging on the microstructure and properties of nuclear-grade 20# pipeline steel, aiming to provide a theoretical basis for the safe and stable application of ice plugging technology in nuclear piping systems.

During monitoring visits to the beaches of Fnideq, M'Diq, Cabo-Negro, and Martil, two jellyfish species along the Moroccan Northwest Mediterranean coast have been observed. Rhizostoma luteum (Quoy JRC, Gaimard JP. Observations zoologiques faites à bord de l'Astrolabe, en mai 1826, dans le Détroit de Gibraltar. Annales des Sciences Naturelles, 1827) was recorded at Fnideq in January 2014, and Cotylorhiza tuberculata (Macri S. Nuove osservazioni intorno la Storia naturale del polmone marino, 1778) was recorded between M'Diq and Cabonegro beach in August 2015. Although their occurrence in the Mediterranean Sea is less frequent compared to the outbreaks of Pelagia noctiluca (Forskål P. Descriptiones animalium, avium, amphibiorum, piscium, insectorum, vermium: quae in itinere orientali observavit. ex officina Mölleri; 1775), these findings represent the first documented records of Rhizostoma luteum and Cotylorhiza tuberculata in this region, contributing valuable insights to the existing knowledge of jellyfish distribution in the Mediterranean.
