This paper is devoted to the MIMO control of the catalytic reverse flow reactor (RFR) which aims to reduce the amount of volatile organic compounds (VOCs) released in the atmosphere. The RFR is characterized by the periodic reversal of the gas flow that aims to trap the heat of reaction inside the RFR. The control issue is to confine the hot spot temperature inside an envelope (in order to ensu...

A research effort was carried out at the Bhabha Atomic Research Centre (BARC), Mumbai, for developing laser-based techniques for enrichment of natural uranium to reactor-grade (2.5% to 3.0% U), with the potential to be economically scalable to industrial production. Three approaches – two molecular, namely CO2 laser-based approach and UF6-based approach, and one atomic, namely Atomic Vapour Las...

The chemistry of electric discharge driven oxygen iodine lasers (EOIL) has long been believed to have O2(aΔg) as the sole energy carrier for excitation of the lasing state I(P1/2), and O(P) as the primary quencher of this state. In many sets of experimental measurements over a wide range of conditions, we have observed persistent evidence to the contrary. In this paper, we review our experiment...

STARFIRE A CONCEPTUAL DESIGN OF A COMMERCIAL TOKAMAK POWER PLANT. Starfire is a conceptual design for a commercial tokamak power plant based on the deuterium/tritium/lithium fuel cycle. The emphasis of the study is on the simplicity of the engineering design, maintainability, lower electricity cost, and improved safety and environmental features. The reactor has a 7-m major radius and produces ...

The Bush Administration has made the expansion of nuclear power generation a centerpiece of its domestic energy policy. However, the White House has not addressed the practical issue of how to overcome the nearly three-decade-long aversion among U.S. electric utilities to investing in new nuclear plants. In today's deregulating market, utilities will not build new nuclear power plants unless th...

The self-consistently generated current-free electric double layer (DL) is shown to scale up with the source tube diameter and appears not to be affected by rf driving frequency and changes in reactor geometry. This Letter presents the first simultaneous measurements of local plasma potential and beam energy as a function of axial position. The DL is shown to be no more than 5 mm thick (20 D le...

Nuclear reactor pressure vessels are often required regular inspection and maintenance in order to ensure the safety of the reactors. Failing to carry out proper maintenance could cause severe casualty. The usual way of carrying out inspection in these hazardous environments is using long reach fixed base manipulators. However, these manipulators suffer from low payload capacity and relatively ...

A plasma-enhanced chemical vapour deposition reactor has been developed to synthesis horizontally aligned carbon nanotubes. The width of the aligning sheath was modelled based on a collisionless, quasi-neutral, Child's law ion sheath where these estimates were empirically validated by direct Langmuir probe measurements, thereby confirming the proposed reactors ability to extend the existing she...

In this work, silicon nitride thin films have been deposited by Plasma Enhanced Chemical Vapour Deposition (PECVD) on both silicon samples and AlGaN/GaN High Electron Mobility Transistors (HEMT) grown on sapphire substrates. Commercial parallel-plate RF plasma equipment has been used. During depositions, the dissociation rates of SiH4 and NH3 precursors and the formation of H2 and N2 have been ...
