Development and trials of a technology for reprocessing of NPP liquid radioactive wastes

Laboratory trials of a process for sorption decontamination of real NPP bottom residues from Cs radionuclides with Termoksid-35 ferrocyanide sorbent and rig and pilot trials of the technology for reprocessing of bottom residues from a number of Russian nuclear power plants were performed. The efficiency of the Cs sorption drastically decreases in the presence of organic complexing agents (EDTA, oxalate ions). Preliminary ozonation of the bottom residue allows the working life of Termoksid-35 sorbent in the decontamination process to be increased by a factor of several tens. Rig and pilot trials showed that ozonation of bottom residues, followed by microfiltration separation of the precipitate formed, ensures efficient decontamination of the solutions from Co, Mn, and Sr radionuclides and from α-emitters. A technology was suggested for decontamination of NPP bottom residues from radionuclides, involving ozonation, microfiltration, and selective sorption of Cs radionuclides on Termoksid-35 ferrocyanide sorbent. Process and technical solutions obtained in the course of trials were implemented in an industrial installation for reprocessing of bottom residues from the Kola NPP.     

“Roll-out” mechanics of glass sheet manufacture—I. Computational solutions for the elastico-viscous regime

A manufacturing process for glass sheet production is investigated. In the process, molten glass is formed into a continuous sheet which is conveyed on a long train of supporting rollers until it is cool enough to be cut into sheets of required length. A mathematical model for the structural behaviour of the sheet in this “roll-out” operation is formulated. In this model the glass is treated as a simple Maxwell elastico-viscous material with temperature-dependent viscosity. The sheet is considered as a continuous beam in horizontal translation over the rollers. Computational solutions for the sheet deflection, obtained with the aid of certain analytical results (derived elsewhere), are given for a variety of boundary conditions. These solutions are found to be in good agreement with observed process behaviour.

Ultrapurification of archaeological lead

Based on purification efficiency calculations for lead distillation, we developed a combined process for the ultrapurification of archaeological lead. We obtained pilot amounts of high-purity archaeological lead and PbO with the following contents of detrimental impurities: U, <2 ppb; Th, <1 ppb; Ni, Cu, Fe, Si, Ti, Mg, Al, Mn, Cr, V, Co, < 0.1 ppm; K, Ca, Zn, Cd, Ag, Sb, < 1 ppm. Lead of such purity can be used in low-background experiments as a protective shield material and in the growth of low-background PbWO₄ and PbMoO₄ scintillator crystals. From an isotope ratio, we were able to identify the origin of the archaeological lead.     

Optical retrodirective tracking system approach using an array of phase conjugators for communication and power transmission

A new concept for a retrodirective tracking system applicable for communication and power transmission is proposed. In the proposed concept, the power transmitter utilizes a receiver's pilot signal to obtain information about its direction by conjugating the signal's phase inside a nonlinear medium. Power is therefore transmitted back to the receiver by the phase-conjugated signal beam. The power can be concentrated by an array of phase conjugators, which provides a large aperture so that the intensity can be increased on the receiver's photovoltaic panels compared to a single element. Controlling the phase and the direction of the readout beams in the four-wave-mixing process provides control over the interference pattern, its position, and its size. A numerical analysis is given for the phase and spot size control, and measurements with two Co-doped Sr(x)Ba(1-x)Nb(2)O(6) (Co:SBN) crystals confirm the occurrence of interference that is achieved for the case of two beams.     

Project Development and Public Relations in Consulting Engineering

ABSTRACT

Engineering consulting firms have historically paid little attention to client and public relations strategies. Only in recent years have professional engineering journals carried articles on business and marketing plans or supported advertising and programs to manage client account potential.

But now, the critical role of public relations within the systematic development of client potential is being recognized as an essential ingredient in reaching and influencing targeted groups of clients in today's global economy. The marketing-selling of consulting engineering services is clearly a management process-analytical, rational, and thoughtful. Engineering managers may spend years developing an intuitive approach to the client development process yet be unable to specify its dimensions and characteristics.

This paper presents a conceptual framework for understanding how public and client relations program efforts contribute to clear and purposeful project development. The argument for crafting the public image of the firm is demonstrated by a case study that examines the client account management methods of a consulting engineering organization.

High-pressure torsion for production of magnetoresistance in Cu–Co alloy

The process of high-pressure torsion (HPT) was applied to control the size and distribution of ferromagnetic Co particles in a Cu–Co alloy. Electron probe microanalysis, X-ray diffraction analysis, and transmission electron microscopy confirmed that the Co particles were significantly refined through fragmentation and dissolved with intense straining by HPT. Magnetoresistance appeared by ~2.5% at 77 K with an isotropic feature corresponding to giant magnetoresistance (GMR). It is demonstrated that HPT is a potential process for creating GMR in the Cu–Co alloy prepared by conventional ingot metallurgy.
