title: Stability analysis on flow parameters in coolant temperature control system of lead-cooled fast reactor

description: Lead-cooled Fast Reactor (LFR), one of the promising nuclear energy technologies for future advanced system, is well foreseen in meeting the goals of Generation IV fission reactor. In LFR, Coolant Temperature Control System (CTCS) is one of the critical parts, and the influence of coolant flow parameters on the stability analysis is worth investigating and studying. In this paper, we use the CLEAR-S, an integrated multifunctional nonnuclear test facility, as reference and the stability analysis of CTCS, concerned to coolant flow rate has been completed based on simplified coolant thermal circulation model. Location of eigenvalues and calculation results of real stability radius, both qualitatively and quantitatively reflect the influence of coolant flow rate on stability respectively. The analysis results show that the feed-water flow rate in steady state is a critical parameter for CLEAR-S, because larger feed water flow rate can improve stability apparently. However, LBE coolant flow rate has little impact on system stability. The results of this work will provide an effective reference for design and operation of LFR.

title: Particle swarm evolutionary computation-based framework for optimizing the risk and cost of low-demand systems of nuclear power plants
title: Particle swarm evolutionary computation-based framework for optimizing the risk and cost of low-demand systems of nuclear power plants

description: In this paper, an adapted multi-objective multi-swarm co-evolutionary particle swarm optimiza tion (PSO) framework is developed to simultaneously optimize the risk and cost of low-demand systems of nuclear power plants (NPPs). In the built framework, multi-swarm co-evolutionarystrategy is introduced to handle the fitness assignment puzzle of multi-objective optimization problems. Besides, to deal with the mixed-integer problem of the decision variables vector, a sub-interval covering-based nearest boundary method is also adopted. To illustrate the effective ness and efficiencies of the proposed method, a typical high-pressurized injection system (HPIS) is analyzed. The results indicate that, compared with the classic non-dominated sorting genetic algorithm (NSGA)-II approach, the proposed method is more simple and easier to be convergent, besides, of which the Pareto front is better distributed

title: ANALYSIS OF THE BASELINE DRIFT ARTIFACT IN HADAMARD TRANSFORM SEPARATION TECHNIQUES

description: The baseline drift artifact (BDA), namely, the baseline bias between the Hadamard transform (HT) spectrum and the signal averaging (SA) spectrum was unfortunately found in the I IT pulsed separation techniques, which makes the HT analytical chemistry face the challenge of non-stability and unreliability. In order to find out the origin and eliminate the BDA phenomenon, the multiplexing mechanism of Hadamard transform ion mobility spectrometry (HT-IMS) has been analyzed in this research. Through simulation and experimental comparisons, the non-ideal overlap defect in Hadamard multiplexing process was suggested as the cause for the BDA phenomenon. Eventually, with a correction method, the BDA phenomenon could be well addressed, which guarantees the reliability and stability of HT techniques without increasing the hardware complexity.

title: Reliability evaluation of integrated detritiation system for fusion reactors based on DBDT approach
title: Reliability evaluation of integrated detritiation system for fusion reactors based on DBDT approach

description: Integrated detritiation system (IDS) would play a key role in controlling the tritium release and atmosphere cleanup under accident scenarios in fusion reactors, and thus it is very significant to evaluate and ensure its reliability. Up to now, many conceptual designs for IDS have been developed worldwide, yet few are focused on its reliability studies. Due to complex redundant designs and functional dependence, this system has notable temporal failure behaviors that traditional static fault trees (SFT) are unavailable to capture and evaluate. In this contribution, motivated to understand the effect of temporal failure behaviors on reliability of IDS, dynamic fault trees (DFT) are first to be adopted to study its reliability through using dynamic binary decision tree (DBDT) approach. The results show the reliability indexes for IDS calculated by DFTs are one to two times lower than those obtained by traditional SFT, which means some overly conservative reliability requirements on IDS could be relaxed. The results also demonstrate that the DFT-based reliability evaluation method would be of great help for the fusion energy system’s optimization design in the future.

title: Influence of growth oxygen pressure on the electrical properties and phase transformation of the epitaxial (K,Na)NbO3-based lead-free ferroelectric films

description: The influence of the growth oxygen pressure (GPO(2)) on the performance of the epitaxial 0.95(K0.49Na0.49Li0.02)(Ta0.2Nb0.8)O-3-0.05CaZrO(3) with 2 wt. % MnO2 addition (KNNLT-CZM) lead-free ferroelectric films grown on the La0.07Ba0.93SnO3-coated SrTiO3 (001) substrates is investigated. The x-ray diffraction results show that the tetragonality of the KNNLT-CZM films is dependent on GP(O2), which varies from 0.999 at 15 Pa to 1.006 at 35 Pa. Since the polarization direction with applied electrical field of the (010)-oriented KNN-based film is along [110]/[011], the relationship between the ferroelectricity and GP(O2) is well explained from the perspective of the tetragonality change. The leakage current density of the KNNLT-CZM films is suppressed and the dielectric constant is enhanced from 427 to 1538 at 1 kHz with increasing the GP(O2). Moreover, the orthorhombic to tetragonal phase transition temperature (TO-T) of the KNNLT-CZM films grown at 15 Pa is similar to 180 degrees C, which is much lower than similar to 210 degrees C of those grown at 25/35 Pa. GP(O2) is proven to be an important factor that regulating the ferroelectricity and TO-T of the epitaxial KNNLT-CZM films.

description: Transparent and epitaxial 0.95(K0.49Na0.49Li0.02)(Ta0.2Nb0.8)O-3-0.05CaZrO(3)with 2 wt.% MnO(2)addition (KNNLT-CZM) lead-free ferroelectric film heterostructures are fabricated on the La0.07Ba0.93SnO3(LBSO)-coated SrTiO3(001) substrates using pulsed laser deposition. The optical measurements show that these film heterostructures exhibit good transmittance with a maximum transmittance of similar to 80%. Temperature-dependent dielectric properties demonstrate that the KNNLT-CZM films possess a high Curie temperature (T-C) above 420 degrees C, and exhibit an orthorhombic to tetragonal phase transition at similar to 170 degrees C. Furthermore, these film heterostructures also have a large twice remnant polarization of 29.66 mu C cm(-2)and well-defined ferroelectric hysteresis loops up to 200 degrees C. The x-ray photoelectron spectra suggest that partial K elements did not enter in the lattice of the KNNLT-CZM perovskite structure and the Mn dominantly existed in the form of Mn2+. The observed good transmittance, high(C) and excellent electrical properties of the LBSO-buffered KNNLT-CZM film heterostructures indicate that these films have great application potential in opto-electronic devices and film transistors.

title: A numerical simulation method for a repairable dynamic fault tree
title: A numerical simulation method for a repairable dynamic fault tree

description: Dynamic fault trees are important tools for modeling systems with sequence failure behaviors. The Markov chain state space method is the only analytical approach for a repairable dynamic fault tree (DFT). However, this method suffers from state space explosion, and is not suitable for analyzing a large scale repairable DFT. Furthermore, the Markov chain state space method requires the components’ time-to-failure to follow exponential distributions, which limits its application. In this study, motivated to efficiently analyze a repairable DFT, a Monte Carlo simulation method based on the coupling of minimal cut sequence set (MCSS) and its sequential failure region (SFR) is proposed. To validate the proposed method, a numerical case was studied. The results demonstrated that our proposed approach was more efficient than other methods and applicable for repairable DFTs with arbitrary time-to-failure distributed components. In contrast to the Markov chain state space method, the proposed method is straightforward, simple and efficient.

title: An upward 9.4 T static magnetic field inhibits DNA synthesis and increases ROS-P53 to suppress lung cancer growth

description: a b s t r a c tStudies have shown that 9.4 Tesla (9.4 T) high-field magnetic resonance imaging (MRI) has obvious advantages inimproving image resolution and capacity, but their safety issues need to be further validated before their clinicalapproval. Meanwhile, emerging experimental evidences show that moderate to high intensity Static MagneticFields (SMFs) have some anti-cancer effects.We examined the effects of two opposite SMF directions on lung cancer bearing mice and found when the lungcancer cell-bearing mice were treated with 9.4 T SMFs for 88 h in total, the upward 9.4 T SMF significantlyinhibited A549 tumor growth (tumor growth inhibition=41%), but not the downward 9.4 T SMF. In vitro cellularanalysis shows that 9.4 T upward SMF treatment for 24 h not only inhibited A549 DNA synthesis, but alsosignificantly increased ROS and P53 levels, and arrested G2 cell cycle. Moreover, the 9.4 T SMF-treatments for88 h had no severe impairment to the key organs or blood cell count of the mice.Our findings demonstrated the safety of 9.4 T SMF long-term exposure for their future applications in MRI, andrevealed the anti-cancer potential of the upward direction 9.4 T SMF.
