Impact of nickel and iron on PWR zirconium alloy surface CRUD formation and boron precipitation
He jishu, 2022 BackgroundCorrosion products will deposit on the surfaces of PWR (pressurized water reactor) zirconium alloy to form CRUD (chalk rivers unidentified deposit), the precipitated boron will cause axial power distribution anomaly and affect the core safety ...

Insect Lipids as Novel Source for Future Applications: Chemical Composition and Industry Applications-A Comprehensive Review. [PDF]
Food Sci NutrFat body (FB) acts as a major metabolic center important for the regulation of a variety of physiological processes such as embryogenesis, reproduction, flight, overwintering, protection, and communication. Lipid amounts and fatty acid (FA) composition vary with species, stage of life, and their diet.

Chemical composition of crud depositing on BWR fuel surfaces.
Journal of Nuclear Science and Technology, 1987 Deposition profiles of corrosion products on fuel surfaces and products chemical compositions were determined at Shimane Nuclear Power Plant, a low-crud BWR. The deposited amounts were expressed as functions of crud concentration in the reactor water, fuel burnup and flow velocity in a fuel channel.

An integrated framework for the prediction of axial offset anomaly in pressurized water reactors [PDF]
International Journal of Fluid EngineeringDuring the operation of pressurized water reactors, erosion products can be deposited on the surfaces of the fuel rods, and these deposits lead to enrichment of boric acid, which influences the power distribution along the axial direction and results in ...

BOTANI: High-fidelity multiphysics model for boron chemistry in CRUD deposits
Nuclear Engineering and Technology, 2021 We develop a new high-fidelity multiphysics model to simulate boron chemistry in the porous Chalk River Unidentified Deposit (CRUD) deposits. Heat transfer, capillary flow, solute transport, and chemical reactions are fully coupled. The evaporation of coolant in the deposits is included in governing equations modified by the volume-averaged assumption ...

Effect of TiN Coating on the Fouling Behavior of Crud on Pressurized Water Reactor Fuel Cladding
, 2021 A titanium nitride film was applied to mitigate the deposition of fouling deposits (crud) on pressurized water reactor fuel cladding. Titanium nitride was chosen as it reduces the van der Waals force, believed to be the dominant surface force at ...

The Economic History Review, EarlyView.Abstract Housework is central to feminist calls for recognition of women's work, economic histories explaining the sexual division of labour, and claims regarding the progressive role of scientific knowledge. Yet little is known about the time it actually took. We address this lacuna.
