This study quantitatively analysed the influence of cooling water parameters on performance a modular high-temperature gas-cooled reactor (MHTGR) nuclear power plant (NPP). The secondary circuit system and cold-end were modelled using EBSILON software, version 16.0. inlet temperature mass flow rate thermal was over full range with goal optimising net power. Under 100% rated condition, for each 1 °C increase in between 10 33 °C, cycle efficiency decreased by 0.67 MW 0.14%, respectively,...

SUMMARY In quasi‐static tests for structures with multi‐DOF, the forces exerted to commonly follow a prescribed force profile, example, triangular pattern and/or uniform pattern. Therefore, control is natural choice. However, no longer applicable when specimens sustain significant stiffness and strength degradation, particularly in collapse tests. To solve this problem, force–displacement mixed algorithm proposed, which able achieve stable following profiles. On basis of FlexTest IIm...

Nuclear energy enables large-scale carbon-free hydrogen production, and the coupling of very-high-temperature gas-cooled reactor iodine–sulfur (IS) cycle has potential to achieve efficient production. This study develops flowsheet IS process, performs process simulation, designs internal heat exchange network using pinch point technology, discusses thermal efficiency production in detail. The results show that if all released by exchangers H2SO4 HI sections can be fully recovered utilized,...

Abstract A new series of multifunctional sensitive ferroelectric ceramics, BaTiO3-BaSnO3 have been studied. They can rapidly detect temperature, humidity and gas presence by means a single sensor. This is the first time that such sensors reported. The crystalline phase, porous structure, pore system, semiconduction temperature-humidity-gas sensing characteristics BTS ceramics were investigated.

Main content extraction of web pages is widely used in search engines, aggregation and mobile Internet browsing. However, a mass irrelevant information such as advertisement, navigation trash included pages. Such reduces the efficiency processing content-based applications. The purpose this paper to propose an automatic main method In method, we use two indicators describe characteristics pages: text density hyperlink density. According continuous distribution similar on page, estimation...

The sulfuric acid decomposer is the key equipment of iodine-sulfur cycle to achieve hydrogen production utilizing high temperature very high-temperature gas-cooled reactor (VHTR). This study discusses design and pipeline layout improve performance based on a shell-and-tube heat exchanger with bayonet as core. finite volume method was used numerically calculate transfer, distribution, baffle layout, sulfur trioxide decomposition rate in decomposer. results show that convective transfer...

The heat generated in a high-temperature gas-cooled reactor can be used to drive the iodine-sulfur cycle produce hydrogen. However, sulfuric acid decomposition step requires sophisticated decomposer increase rate. of mainly occurs catalytic zone, and optimization its structure is very important for increasing This study focuses on structural design zone unit. with double inner tubes designed analyze influence tube transfer area volume annulus region species transport model predict proportion...

This paper presents an embedded platform for image acquisition and processing. It is based on the Texas Instruments' TMS320C6416T, a high performance digital signal processor Altera's FPGA EP3C25F324, offering 594Kbits memory, which enough to design large FIFO (first in first out) chip. The data transferred into FPGA, after pre-processing, it DSP6416 by interface of EMIF. Then processed DSP real time algorithms. And this system provides LVDS displaying real-time CAN communication with other...

Nuclear hydrogen production has the advantages of large-scale and low carbon emissions, is expected to play an active role in energy transition process. However, storage transportation pose potential risks leakage diffusion when connected high-pressure tanks pipelines. To address this concern, study focused on designing three distinct safety improvement schemes tailored for accidents. These encompassed a passively distributed arrangement obstacles (Scheme 1), centralized 2), fan array...

Background: Adolescent-specific ADHD self-report screening measures can greatly increase the likelihood of correct diagnosis and timely treatment in adolescents. This study provides preliminary evidence for evaluating reliability validity Adult Self-Report Scale-Revised (ASRS-R) a school-based sample Chinese Methods: The ASRS-R Strengths Difficulties Questionnaire (SDQ) were administered to 867 adolescents aged 12 16 years ( M age = 13.08 years). Construct was assessed using correlation...

The paper presents an experimental study on a new type viscoelastic damper, which is expected to have better energy dissipation capability. Tests the dampers’ mechanical properties, including shear storage modulus, loss and factor, were conducted using reduced scale specimens, took strain amplitude, loading frequency ambient temperature as test parameters. Aging tests, low cycle high fatigue tests also conducted. Particularly, behavior under of 300% basic strains 300%-420% investigated. Test...
