Sensitivity and Uncertainty (S&U) analysis plays a major role in reactor physics. Uncertainty in reactor engineering comes from model error, numerical error and input parameter error. Nuclear data are regarded as crucial input parameters and proven to be a major uncertainty source. Therefore, effective evaluation of nuclear data can promote the accuracy and fidelity of nuclear system simulation. In deterministic codes, however, most studies about S&U analysis are based on the traditional two-step method, i.e. assembly calculation and core simulation. With the development of advanced 2-D/l-D transport codes, the corresponding S&U analysis model is required. A new S&U analysis code, namely KYADJ, achieved the sensitivity analysis of eigenvalue with respect to material macroscopic cross sections based on classical perturbation theory. Forward and adjoint flux were solved by the coupling of 2-D Method of Characteristics (MOC) and 1-D discrete ordinates method (Sn). Besides, the Direct Numerical Perturbation (DNP) method in KYADJ and the Iterated Fission Probability (UP) method in reactor Monte Carlo code (RMC) were adopted to calculate sensitivity coefficients for comparison. A 3x3 pin-cell benchmark and 3-D OECD/NEA C5G7 benchmarks were applied to verify the ability of sensitivity analysis in KYADJ. Results showed that a good agreement among three approaches was achieved. KYADJ can accurately calculate eigenvalue sensitivity coefficients with respect to input nuclear data. © 2018 International Conference on Physics of reactors, PHYSOR 2018: reactor Physics Paving the Way Towards More Efficient systems.

The capacitive Pulse power supply is widely utilized in the electromagnetic launch system. And the ideal launcher current is in the square-shape. To solve the problem of the precise current control of the supply, a new control strategy is proposed based on the prediction of the peaks of the output current. First, the mathematical model is built for the system composed of the capacitive Pulse power supply and the rail-type electromagnetic launcher. Then the time sequential control strategy is proposed. And the effectiveness of the proposed method is validated by simulation. Based on the proposed strategy, the local peaks of the output current and the peaks of the acceleration can be precisely controlled as required, which is essential for the design of the guided projectile.

A pinacol boronate caged NIAD-4 derivative as a near-infrared fluorescent probe for fast and selective detection of hypochlorous acid

Chinese Chemical Letters 2018年第1期29卷 139-142页

Hypochlorous acid （HOCI） is one of highly reactive oxygen species （ROS）. It is involved in both immune defense against invading microbes and the progression of many diseases including cardiovascular disease and neurodegeneration disorders. It is generated from hydrogen peroxide （H2O2） and chloride ions in the presence of myeloperoxidase in activated neutrophils. To illustrate HOCI＇s biological functions, fluorescent probes, particularly those fluorescence emissions are in the near-infrared range, are highly needed for in vivo applications. Herein, we reported the design of a pinacol boronate caged near-infrared （NIR） fluorescent probe I derived from an Aft binding fluorophore NIAD-4 for fast and selective detection of HOC1/C10 over other ROS. Upon exposure to HOCI/CIO-, the pinacol boronate caging group of the probe 1 was quickly converted to electron-donating hydroxyl group, which increased intramolecular charge transfer OCT） in the excited state and resulted in the red-shift and intensity enhancement of fluorescence emission. The probe bears several unique features：（1） It could be used as either a ratiomatic or turn-on fluorescent probe; （2） Reaction of the caging group boronate with HOCI is very fast and finishes within seconds, which provides the selectivity over H2O2; （3） The NIAD-4 fluorophore provides additional selectivity for detection of HOCl over peroxynitrite. Moreover, the utility of the probe in imaging HOCllClO- was demonstrated in in vitro phantom imaging studies using mouse brain homogenate as biological relevant media.

The large thermal energy in launching because of high-current and high-speed affect the engineering application of electromagnetic rail launcher. In this paper, considering the inductance gradient and the resistance gradient, the circuit model of Electromagnetic Rail Launcher including PFN, rail, armature and cable is established, the motion model of armature position, speed and current are taken for interative analytical calculation by using Matlab. The data contrast with other literature and experimental shows that the model is correct and effective. The heating effect analysis of Electromagnetic Rail Launcher include Joule energy of rail resistance, cable and induction, friction energy between armature and rail, etc. Comparison with the kinetic energy of projectile, the thermal energy of rail including resistance and friction and Joule energy of cable take a large proportion in system energy. The paper provides a basis for the cooling design of Electromagnetic Rail Launcher.

With the development of electronic equipment integration technology, the air demand for cooling in cabin and electronic system is increasing continuously. The ram air outlet plays an important role in the airflow system. In this paper, the three-dimensional modeling of the door-type ram air outlet and the grille-type ram air outlet is carried out. Then, the flow characteristics and resistance characteristics of ram air outlet are analyzed based on structured grid technology. The results show that the flow rate of the door panel ram air outlet is greater than that of the grille-type ram air outlet in the same size, the discharge rate of the door panel outlet is 0.3kg/s more than that of the grille-type outlet under the design condition, and the skin surface temperature at the back of the door panel outlet is 13.5K lower than that of the grille outlet. Therefore, the door-type ram air outlet has better emission characteristics and flow characteristics, which is more suitable for the aircraft in this research. This study provides a technical reference for the design of the civil aircraft.

In the severe high-temperature environment caused by aerodynamic heating, the vibrational excitation, dissociation and ionization of gas may successively occur, which are known as real gas effects. Under the real gas effects, the thermodynamic properties of gas vary drastically and significantly influence the performances of the active thermal protection system of hypersonic vehicles, especially in the case with coolant outflow, for example transpiration cooling. This paper numerically investigates the transpiration cooling performance with the consideration of the interaction between coolant outflow and hypersonic flow under the real gas effects. The mathematical models and coupled numerical strategy are firstly validated by experimental data, then the influences of real gas effects on the transpiration cooling of a wedged leading edge (WLE) are studied under a flight Mach number range from 8 to 12 and a flight height of 40 km. The analysis and discussions of the numerical results reveal some important phenomena and demonstrate the need to consider real gas effects.

Because of the high temperature and high pressure characteristics of supercritical water-cooled reactor (SCWR), the thermal hydraulic performance of SCWR is greatly different from pressurized water reactor (PWR), which makes the current PWR fuel rod performance analysis codes are no longer applicable to SCWR. In this research, the irradiation swelling, irradiation densification, thermal expansion, thermal creep, plastic deformation, irradiation creep and irradiation hardening of UO2 pellet, and stainless steel cladding were considered;the gas conductance and radiant conductance of gap heat transfer were considered, the forced convective heat transfer on the outer surface of cladding was considered. Meanwhile, the irradiation effects and the thermal effects on the materials parameters such as thermal conductivity, specific heat, and young’s modulus were also considered in this research. With the help of ABAQUS software, the related user-defined subroutines were developed, and the irradiation effects and thermal effects of SCWR fuel were introduced into the numerical simulation, and then completed the analysis of SCWR fuel rods’ performance under steady power conditions. Some reference suggestions for the design and development of SCWR fuel could be provided by the establishment of this numerical simulation method. Copyright © 2018 by ASME.
