Helium is a by-product of the tritium formation reaction by neutron bombardment lithium. The solubility helium estimated to be extremely low, which may result into gas pockets formation. These then cause hot spots within blanket, reduce its shielding properties and also breeding ratio limiting Pb-16Li volume inside blanket. To assess extent bubble formation, simplified model single sector European DEMO blanket had been developed local production rates gaseous have estimated. Based on recent...
Abstract Heavy liquid metal (HLM) cooled systems are under wide investigation and development. The technology needs to study the materials corrosion, which has a different progress than corrosion caused by aqueous media. Improvement of resistance can be achieved alloying bare material, but degradation steels continues with less or more intensity. Deposition protective barrier may reduce metals dissolution diffusion lead into steel substrate. Different types surface treatment coatings...
Oxygen has a fundamental role for the safe operation of GEN IV reactors cooled by Heavy Liquid Metals, HLM. The use oxygen sensors and dosing gas in environment are key issues chemistry control HLMs, particular when corrosion structural materials is concern. In fact, concentration must be high enough to grow protective oxide scale on surface construction (steels) order prevent their dissolution liquid metal. On other hand, certain threshold not exceeded precipitation oxides within flow paths...
Abstract Development of liquid lead cooled nuclear systems requires consideration compatibility issues with the construction materials. In order to understand corrosion or passivation behavior 316 L austenitic stainless steel, steel specimens were exposed for 1000 h in 1 × 10−7 wt % oxygen level at 480 °C static and flowing (velocity 1.6 m/s) conditions. Post-test microscopy investigation using scanning electron microscope focused ion beam (FIB) was performed it demonstrated significant...

Abstract This work deals with behaviour of steel in liquid lead environment and possibilities corrosion resistance improvement. Liquid metal cooled systems are under wide investigation development represent a good alternative. It is necessary to find materials, which would be affected by minimally. Austenitic 316L without coating coated TiSiC was studied flowing lead. Conditions the experiment simulated real system. Deposition protective barrier reduced metals dissolution diffusion into...
