A fusion-driven subcritical system concept based on viable technologies

Abstract

A fusion-driven hybrid subcritical system (FDS) concept has been designed and proposed as spent fuel burner based on viable technologies. The plasma fusion driver can be designed based on relatively easily achieved plasma parameters extrapolated from the successful operation of existing fusion experimental devices such as the EAST tokamak in China and other tokamaks in the world, and the subcritical fission blanket can be designed based on the well-developed technologies of fission power plants. The simulation calculations and performance analyses of plasma physics, neutronics, thermal-hydraulics, thermomechanics and safety have shown that the proposed concept can meet the requirements of tritium self-sufficiency and sufficient energy gain as well as effective burning of nuclear waste from fission power plants and efficient breeding of nuclear fuel to feed fission power plants.

Deformable image registration of CT images for automatic contour propagation in radiation therapy

“…The average computational time of the proposed method was approximately 35 minutes (the size of CT was down-sampled to 128×128×40) with CPU. Next, we will attempt to speed up the proposed method and aim to apply our ARTS-IGRT system [4][5][6][7][8][9][10][11][12][13] to clinical practice. In addition to the processing time, automatic contour propagation could be applied not only to mono-modality images (such as CT-to-CT), but also to multi-modality images (such as CT-to-MR).…”

Performance test of electromagnetic pump on heavy liquid metal in PREKY-I facility

“…Fusion and fission energy are the important ways recognized so far to solve the energy crisis problems [1][2][3][4][5][6][7]. Fusion reactor liquid lithium lead blanket, because of its inherent characteristics and advantages, is widely recognized internationally as one of the fusion power cladding designs with most promising future [8][9][10][11][12][13][14][15][16][17].…”

Preliminary Cost Assessment and Compare of China Fusion Engineering Test Reactor

“…Proposed roadmap and testing strategy of fusion energy has been being planned based on the assessment and design analysis of the developed series fusion reactors and hybrid system concepts in China [1][2][3][4][5][6][7][8][9][10] as well as a summary of related design and R&D activities in the world. In that development strategy, based on wide survey and analysis of development of the international fusion reactors and related research by FDS Team, a China Fusion DEMO Reactor (C-DEMO) concept has been proposed [11].…”

“…In order to check and validate relevant technologies of C-DEMO based on viable technologies, a fusion engineering experimental reactor will be built in China. Recently, a series of scenarios for test reactor concept have been proposed, such as the Multi-Functional hybrid eXperimental reactor [5,12,13] and the China Fusion Engineering Test Reactor (CFETR) [14].…”
