Three-dimensional model of DEMO-FNS facility considering neutronics and radiation shield problems

Heliyon, 2019
Recent neutronics studies of blankets for tokamak-based demonstration fusion neutron source (DEMO-FNS) showed a crucial influence of coolant composition on the transmutation rate of transuranic elements and tritium breeding in the system.

Searching for exotic scalars at fusion reactors

Journal of High Energy Physics
Part of the energy created in deuterium-tritium fusion reactors is carried away from plasma by a high-intensity neutron flux, which is then absorbed by the reactor’s inner walls.

Tritium Extraction from Liquid Blankets of Fusion Reactors via Membrane Gas–Liquid Contactors

Journal of Nuclear Engineering
The exploitation of fusion energy in tokamak reactors relies on efficient and reliable tritium management. The tritium needed to sustain the deuterium–tritium fusion reaction is produced in the Li-based blanket surrounding the plasma chamber, and ...

Progress in EU Breeding Blanket design and integration

Fusion Engineering and Design, 2018
In Europe (EU), in the frame of the EUROfusion consortium activities, four Breeding Blanket (BB) concepts are being developed with the aim of fulfilling the performances required by a near-term fusion power demonstration plant (DEMO) in terms of tritium self-sufficiency and electricity production.

Numerical Investigation and Analytical Modeling of MHD Pressure Drop in Lead–Lithium Flows Within Rectangular Ducts Under Variable Magnetic Field for Nuclear Fusion Reactors

Journal of Nuclear Engineering
The breeding blanket is a key component of tokamaks, primarily responsible for extracting heat from fusion reactions and for tritium breeding, which is essential to ensure a fusion reactor’s fuel self-sufficiency.

The effects of extended photoperiod and warmth on hair growth in ponies and horses at different times of year.

PLoS ONE, 2020
Photoperiod is considered the most dominant environmental cue allowing animals to anticipate and adapt to seasonal changes. In seasonally breeding mammals, changes in daylength alter pineal melatonin secretion and pituitary prolactin secretion.

Accident-tolerant hybrid ceramics for fusion breeding blanket

Materials & Design
In a water-cooled ceramic breeding blanket for fusion reactors, hydrogen gas generation by steam oxidation of metallic Be compounds (i.e. neutron multiplier) in a loss-of-coolant accident (LOCA) raises major safety concerns. Li–Be hybrid ceramics has a potential to reduce hydrogen generation significantly, however, the stable compositions and ...

A novel solution for hydrogen monitoring in fusion processes: 3D printed BaCe0.6Zr0.3Y0.1O3-α sensors

Nuclear Materials and Energy
The control of tritium (3H) in liquid-based tritium breeding blankets (TBBs) is one of the key points to assure their correct performance to prove the 3H sufficiency.

Analysis of a segmentation approach to breeder blanket design and the utilisation of FLiBe as a novel neutron reflector

Nuclear Fusion
Tritium production in a fusion reactor is essential for a deuterium-tritium burning plasma source, and designing a lithium-containing breeder blanket is crucial for a closed fuel cycle in an electricity-to-grid power plant.
