Rotational Symmetry Boundary Condition in Current Coupled Whole Core Pin by Pin Transport Theory Code

Posted on Updated on

The advances in PC handling power have made it conceivable to play out an itemized stick by stick figuring of the entire center. The techniques in light of reaction grid are being utilized to perform entire center transport counts. This incorporates the current coupled techniques in light of 2D crash likelihood (CP) and strategy for trademark (MOC). The essential approach in the entire center transport hypothesis strategies isn’t to homogenize the cross section cells and subdivide every cell area in the fuel get together (FA) into better districts. The coupling of cross section cells inside the get together and get together to gathering coupling can be accomplished utilizing interface streams. Because of fine discretisation of the cross section structure and substantial center size, the physical memory necessities for the entire center reenactments are colossal. This necessity is exacerbated if ultra-fine discretisation of vitality space is likewise considered. At the point when there is an inborn symmetry one can fathom for the symmetric bit of the center, along these lines spare both memory and computational time. Rotational symmetry limit condition in the entire center is regularly considered. Utilization of this limit condition gets exceptionally convoluted when the entire center is demonstrated by a stick by stick approach. The present paper depicts the procedure to apply the rotational symmetry limit condition in the center discretized with complex microstructures of different heterogeneous cells of the issue.

Post-Fukushima Nuclear Power Plant Safety-A Review

Posted on Updated on

Nuclear power plant (NPP) supplies large scale electrical power at competitive price as a base load to electrical grids. However, safety has been major concern due to potential release of radioactive material from an accident. Though historically the nuclear industry has good safety record there have been three major accidents, Three Mile accident, Chernobyl accident and recent Fukushima accident. The article summarizes the reactor safety technology and briefly reviews these three major accidents along with key lessons learned. In the light of Fukushima accident both industry and regulators are reassessing safety of NPP and have taken measures to address new safety challenges raised from the recent accident.

Oxidation Number, Oxidant and Reductant as Derivative Concepts within GATES/GEB Formulation

Posted on Updated on

Formulation of Generalized Electron Balance (GEB) according to Approach II to GEB, based on linear combination f12 = 2∙f(O) – f(H) of elemental balances: f(H) for H and f(O) for O, is illustrated on the titration of NaBr + H2SO4 (as titrand, D) with Ce(SO4)2 + H2SO4 solution (as titrant, T), according to GATES/GEB principles. Some fundamental advantages inherent in linear combination of f12 with other elemental/core balances are indicated. The prior information on oxidation numbers of all elements participating the redox system is not needed. The multipliers needed to obtain the simpler form of the balance resulting from the linear combination are equal to oxidation numbers of the elements participating the related system. This way, the f12 provides the criterion distinguishing between non-redox and redox systems. The f12 is linearly independent on other balances in a redox system, or linearly dependent in non-redox systems; the D and T are considered here as non-redox subsystems of the D+T redox system. All available physicochemical knowledge related to the D+T system can be involved in the iterative computer program used for calculation purposes.

Light Fastness Improvement of Dyed Acrylic Fibers Using UVAbsorbers

Posted on Updated on

The use of UV-absorbers in the dyeing of polyester to improve lightfastness is well known. In analogous manner, in this study the effect of ultraviolet (UV) absorbers on light fastness of acrylic yarns dyed in conventional dyeing process has been investigated. Under optimised dyeing conditions, the samples were dyed with a selection of basic dyes. Consequently, the samples were post-treated with five types of UV-absorbers. Regarding the photo-fading, the postdyeing treatment was evaluated from the reflection spectra in terms of the L, a, b, color coordinates and by measuring the difference ΔE between untreated and treated samples. Samples were subjected to Xenotest and FTIR-ATR spectroscopy, while the morphological structure of the dyed fibres was investigated by scanning electron microscopy (SEM).

Reducing Energy Consumption in Wireless Sensor Networks Using Hash Distribution Table

Posted on

Recent advances in communication technology and microelectronics industry has resulted in industrial level production of small and relatively cheap sensors which communicate over a wireless network. These networks, which are called wireless sensor networks, are appropriate tools for collecting data from the surrounding environment and for monitoring the events there, and their domestic, industrial, and military usages are expanding by the day. The most important challenge in designing and manufacturing a wireless sensor network is limited energy source of the sensors. Due to sheer number of sensors and/ or limited access to them, changing or recharging their batteries would not be a viable option. There is thus a growing consumption of the sensors, which will eventually result in improved lifespan of the network as well. Sending and receiving data packages are the most energy consuming functions over a network and if we can send data packages on the shortest possible routes and with the minimum number of collisions we will be able of extend battery lives and lifespans of nodes.

Design of Miniaturized Dual Band Microstrip Antenna Loaded With Asymmetric J Slot

Posted on

Small dual band patch antennas are very much attractive feature in modern satellite and mobile communication technology due to their low cost, light weight, smaller dimension in size and ease of fabrication. Several dual band microstrip antennas have been proposed in last three decades. Among those, dual frequency operating mode is attained by using multilayer stacked rectangular patches. Frequency ratio controllable dual band microstrip antennas have been proposed.

Wear Properties of PTFE and C3F6 Polymer Coated Carbon Steel Using RF Low-Pressure Plasma

Posted on Updated on

In this study, the surface of AISI 1050 carbon steel has been heat treated with different treatment parameters (fully softened, tempered) and a mechanical surface process (shot peening). Heat treated AISI 1050 carbon steel was coated in an RF vacuum plasma system with different plasma parameters (power, pressure, treatment time and type of gas). Two different coating processes were used: plasma grafting of sprayed polytetrafluoroethylene (PTFE) using argon and helium plasma and thin-layer deposition by hexafluoropropene (C3F6) plasma. The abrasion of coated surfaces was tested. After wear tests, surface morphology was analysed by scanning electron microscope (SEM) and optical microscope (OM). PTFE coating processes were found to be superior to C3F6 plasma processes.
