The Department of Energy’s River Protection Project (RPP) is tasked with retrieving highly radioactive waste from Hanford double-shell and single-shell tanks to provide feed for vitrification for long-term storage. Approximately 330,000 metric tons of sodium-rich radioactive waste originating from separation of plutonium from irradiated uranium fuel is stored in 177 underground tanks at Hanford...

Abstract One of the basic load cases relevant for design shell structures is torsion, which can occur exemplary in silos and tanks under seismic actions or even wind loading. To address stability problem cylindrical shells this case, standard EN 1993‐1‐6 European Recommendation ECCS EDR5 provide simple approaches buckling shells. In order to improve current hand calculation rules given above do...

 In order to investigate the effects of artificial substrates (vertical surface of polypropylene fabrics) on cultured shrimp, we reared 28-day old Litopenaeus vannamei post-larvae (PL28) intensively for 90 days at a density of 510 shrimp/m2 in each of 8 tanks. Two tanks containing no artificial substrate were a control group, and 1, 3 and 5 artificial substrates were present in other 6 tanks. T...

The low-aspect-ratio cylindrical structures represented by oil tanks is a kind of wind sensitive structure, which prone to buckling under wind-loads. A tunnel test was conducted investigate the properties wind-loads acting on smooth cylinders with an aspect ratio AR = 0.323 and 0.875, respectively. Some parameters, such as Reynolds number (Re) turbulence intensity, were taken into account. resu...

In many Mediterranean countries, users store water resources in private tanks, which are typically located on rooftops. These local reservoirs are generally connected directly to the water distribution network (WDN). This installation scheme causes a disconnection of the WDN from the users, and thus, the users’ water supply is no longer linked to their consumption, which changes the network ope...
