“…Type 316LN (Figure5) has lower carbon and higher nitrogen content than type 316, but the two share the same minimum YS, UTS, UE and H specifications per ASTM A240. The extra nitrogen is linked to an increase in YS and UTS at 4.2 K with only moderate decrease in UE[18].Cu10100 Included for comparison. Oxygen-free electronic copper, OFE (formerly OFHC), is 99.99 % Cu minimum.…”

We present measurements of the low temperature thermal conductivity for materials useful in the construction of cryogenic supports for scientific instrumentation and in the fabrication of flat flexible cryogenic cabling. The materials we measure have relatively low thermal conductivity. We present a method for measuring the heat transfer coefficient of flat cabling and show, using an example, that the thermal conductivity of a flex cable is reasonably well predicted by composing the thermal conductivities of its constituent material layers. Room temperature physical and mechanical data is given for the materials studied, as well as an overview of relevant materials science and manufacturing details. Materials include Timet Ti 15-3 and Ti 21S, Materion alloy vit105 (LM105) in amorphous state, ATI Metals Nb-47Ti, Johnson Matthey nitinol (NiTi), Mersen graphite grade 2020, DuPont Pyralux coverlay and Vespel SCP-5050, and Fralock Cirlex polyimide sheets. All data is in the temperature range 0.05 to 2 K, and up to 5 K for SCP-5050. Absolute thermometer uncertainty is ±0.007 K for Nb-47Ti, ±0.02 K for NiTi and ±0.05 K for the other samples.

“…The materials choices were motivated by their mechanical, neutronics and corrosion resistant characteristics as well as their use in other fusion experimental reactors [73,74] and reactor studies [19,42,54,56]. A maximum allowable stress of 750 MPa was used for 316LN-IG stainless steel under 20 K and a maximum allowable stress of 790 MPa was used for Hastelloy C-276 [73,75,76]. The structural materials mass densities and unit costs are summarized in table 2.…”

High Temperature Superconductors expand the design space of stellarator power-plants toward high magnetic fields B, enabling compact major radii $R$. The present paper scans the space of B, R and other design parameters, finding solutions that are promising from a physics and engineering standpoint, while minimizing the capital cost of the power-plant and the levelized cost of fusion electricity. Similarly, it identifies minimum-cost design points for next-step burning plasma stellarator experiments of fusion gain 1 < Q < 10. The study assumes advanced stellarator configurations of reduced aspect ratio, heated by Neutral Beam Injection. Plasma-facing, flowing liquid metal walls protect it from high heat and neutron fluxes. The study relies on analytical first-principle calculations, and established zero-dimensional empirical scaling laws. Power flows are illustrated by Sankey diagrams. Plasma operating contours are used to determine the reactor’s start-up path. Sensitivity analyses are conducted to identify the most critical reactor parameters within physics, engineering and costing, quantifying their influence on the economics of the power plants. Such 0D study suggests that the assumed next generation HTS, flowing liquid metal walls, and advances in compact plasma configurations could lead to an ignited stellarator power-plant of aspect ratio A ~ 4, R ≤ 4 m, B > 9 T, and normalized plasma pressure β ~ 5 % would minimize both the cost of electricity and capital cost while achieving a net electric power of about 1 GW.

“…Material yang biasanya bersifat duktil pada temperatur atmosfer dapat menjadi sangat getas ketika dikondisikan pada temperatur yang sangat rendah, sementara material cryogenic keuletannya lebih meningkat. Beberapa jenis material yang biasa digunakan pada temperatur cryogenic adalah baja stainless steel (SS) 316L (Sas, Weiss dan Jung, 2015), SS 304L (Gupta, 2017), baja 9% Nikel (Hany dkk., 2014), baja Invar (Anoop dkk., 2021), dan aluminium AL 5052 (Gang, Lee dan Nam, 2009).…”

Development of liquified natural gas (LNG) ISO tank in Indonesia pays significant attention due to this product is still imported and it has high LNG market potential. In addition, this research is in line with national research priorities in the maritime sector to implement energy equality in Indonesia. As a first step in the research, the ISO tank model designed by using CATIA and structural testing using ANSYS software for finite element analysis. This simulation test is carried out to identify areas that receive high stress in the tank shell and the support structure of the tank. In addition, this virtual test was conducted to quantify the stress and safety factor of the ISO tank model. With this simulation, it is hoped that a more efficient and safer ISO tank design that meets existing regulatory standards can be obtained.
