CFD Analysis and Optimization of the DEMO WCLL Central Outboard Segment Bottom-Cap Elementary Cell

Journal of Nuclear Engineering, 2022
In the design of magnetic confinement nuclear fusion power plants, the breeding blanket (BB) plays a crucial role since it must fulfil key functions such as tritium breeding, radiation-shielding, and removal of the heat power generated by the plasma. The

Neutronics Assessment of the Spatial Distributions of the Nuclear Loads on the DEMO Divertor ITER-like Targets: Comparison between the WCLL and HCPB Blanket

Applied Sciences, 2023
The Plasma Facing Components (PFCs) of the divertor target contribute to the fundamental functions of heat removal and particle exhaust during fusion operation, being subjected to a very hostile and complex loading environment characterized by intense ...

European DEMO Fusion Reactor: Design and Integration of the Breeding Blanket Feeding Pipes

Energies, 2023
This article describes the design and configuration of the DEMO Breeding Blanket (BB) feeding pipes inside the upper port. As large BB segments require periodic replacement via the upper vertical ports, the space inside the upper port needs to be ...

Sizing of the Vacuum Vessel Pressure Suppression System of a Fusion Reactor Based on a Water‐Cooled Blanket, for the Purpose of the Preconceptual Design

Science and Technology of Nuclear Installations, Volume 2016, Issue 1, 2016., 2016
A methodology to preliminarily evaluate the size of the suppression tank and the relief pipes for a Vacuum Vessel Pressure Suppression System, to be adopted in a fusion reactor based on a water cooled blanket, is presented. The volume of the ST depends on the total energy of the water cooling system and it can be sized based on a required final ...

Endoscopic Laser Treatment for Rectosigmoid Villous Adenoma: Factors Affecting the Results

Canadian Journal of Gastroenterology and Hepatology, Volume 6, Issue 5, Page 301-307, 1992., 1992
Endoscopic laser treatment is now commonly used for palliation of advanced digestive cancers in nonsurgical candidates. lt has also been used for treatment of benign rectosigmoid villous adenoma. The present work reports the long term results in 387 patients with benign rectosigmoid villous adenomas revealed by biopsy.
