[en] In late 1977, the Tennessee Valley Authority (TVA) proposed to build a 2 unit nuclear plant at Phipps Bend on the Holston River east of Surgoinsville, Tennessee. Total estimated cost is 1.6 billion dollars, with a generating capacity of 2,600,000 kilowatts. The facility will have an impact on Hawkins, Greene and Sullivan counties with 2,500 construction employees, a permanent work force of 300, increased availability of energy to stimulate new capital investment and the local government will need to deal with these. This report analyzed the facilities of each community in the impacted area and recommended certain action for infrastructure acquisition or improvements

[en] Curvature extrusion process has several advantages in comparison to the conventional extrusion and bending process. In the curvature extrusion, the extruded part is directly bent during extrusion. Therefore, it does not need additional bending process after extrusion. In the curvature extrusion process, it is possible to produce curved extruded products that have a constant or various curvatures. It is essential that we predict the curvatures of the extruded product to meet the required curvatures. This paper proposed a theoretical model that can predict the curvature of extruded product produced by the curvature extrusion process. Using the proposed model the movement of guide tool that causes the bending of extruded product was controlled to produce the required curved automotive Al bumper back beam. The effectiveness of the proposed prediction model and the movement of guide tool were verified by the FE analysis and curved extrusion experiment

[en] The bending of a carbon nanotube is studied by considering the structural evolution of a carbon nanotorus from elastic deformation to the onset of the kinks and eventually to the collapse of the walls of the nanotorus. The changes in the electronic properties due to delocalized deformations are contrasted with those due to localized deformations to bring out the subtle issue underlying the reason why there is only a relatively small reduction in the electrical conductance in the former case even at large bending angles, while there is a dramatic reduction in the conductance in the latter case at relatively small bending angles

[en] One notable US achievement in 1985 was the completion of River Bend in six years. The River Bend success story reflects the dramatic impact of a unique management-labour agreement; the importance of clear managerial commitment; and the key role of a simplified planning and scheduling control system.

[en] The Reliability Centered Maintenance (RCM) programme at the US River Bend BWR station is the cornerstone of a general programme to hold operation and maintenance (O and M) costs in line while maintaining safety and reliability. The programme combines the Important-to-Reliability, Predictive Maintenance, Preventive Maintenance Review, and System Engineering programmes into one system, which also aims to reduce scrams, reduce regulatory surveillance and help engineers to be more cognizant of their system's status. While it appears that the Reliability Centered Maintenance programme itself is the centre of all this activity (see diagram), the system engineer is the real focus of the entire programme. The RCM programme serves as an information network routing plant data to and from the system engineer in a concise format for use in evaluating plant performance, adequacy of maintenance and the need for modifications to systems and components.

[en] A magnetic system is described which is achromatic and isochronous for deflecting a beam of charged particles through 180 deg. (E.C.B.)

[en] Theoretically achievable minimum emittances of isochronus rings for synchrotron light source are calculated. The rings discussed in this paper consist of isochronus and achromatic bending cells, isochronus TBA (triple bend achromat) cells with negative dispersion, isochronus TBA cells with inverse bends or isochronus QBA (four bend achromat) cells. We show that the minimum emittances of these rings are roughly 2 or 3 times of those of the optimized non-isochronus rings
