Preliminary corrosion studies of P-91 in flowing lead–lithium with and without magnetic field for Indian lead–lithium ceramic breeder test blanket module

To study the corrosion of P-91 (9% chromium and 1% molybdenum) material with lead–lithium (Pb–Li) eutectic, two experiments were carried out in a forced convection loop, at eutectic temperature of 550 °C. The first experiment was carried out at a velocity of 15 cm s−1 for 1000 h and the second experiment, at a velocity of 30 cm s−1 for 2700 h. In both the experiments, P-91 sample coupons were exposed to Pb–Li flow in the presence and absence of magnetic field. Samples were analyzed using an optical microscope, scanning electron microscope (SEM) and electron probe micro-analyzer (EPMA). Micro-Vickers hardness testing was also carried out. Dissolution of elements into liquid metal is the main…

Riga experience in spallation neutron target related investigations

Abstract Mercury has awakened interest as a potential material for spallation neutron source targets. Institute of Physics, University of Latvia has a 30 years experience of investigations in mercury. As specially projected building includes a 350 m2 experimental hall. The largest loop, containing 5×103 kg of Hg, can be transferred for solution of different tasks. As the first example results are presented when integral developed pressure and local (distribution of void fraction) characteristics of a two-phase mercury/gas riser were investigated. Second example – investigation of velocity fields and heat transfer conditions close to the beam entrance window in the SINQ target thermohydrauli…
