A content analysis was conducted of all UK local daily newspaper articles appearing in the first half of 1981, concerned with nuclear power or renewable alternatives. Evaluative coverage of these technologies was compared on dimensions found to characterise energy issues (economic, environmental, technological, future/political, physical and psychological risks). In addition, comparisons were drawn between coverage in areas ‘threatened’ with the potential siting of a new nuclear power station and that in ‘unaffected’ areas. The development stage of the two technologies and the degree of ‘factual’ as opposed to ‘polemical’ coverage they attracted were also recorded. In evaluative terms, nuclear power was evaluated overwhelmingly negatively, and alternatives positively. Moreover, this pattern showed a degree of consistency irrespective of the dimension of evaluation. The ‘threatened’ subsample was most negatively disposed towards nuclear power. Polemical coverage was greater for nuclear power than for alternatives and greatest in the ‘threatened’ sample. This category also contained articles more likely to attract attention because of their greater headline size and length. Whereas most coverage of nuclear power concentrates on preoperational or operational stages, coverage of alternatives is more concerned with its formative and planning stages. These findings were related to people's attitudes concerning nuclear power, and the growth in antinuclear feeling in particular.

The degradation of steam generator tubing at nuclear power plants has become an important problem for the electric utilities generating nuclear power. The material used for the tubing, Inconel 600, has been found to be succeptible to intergranular attack (IGA). IGA is the selective dissolution of material along its grain boundaries. The author believes that the sensitivity of Inconel 600 to IGA can be minimized by homogenizing the near-surface region using ion implantation. The collisions between the implanted ions and the atoms in the grain boundary region would displace the atoms and thus effectively smear the grain boundary.To determine the validity of this hypothesis, an Inconel 600 sample was implanted with 100kV N2+ ions to a dose of 1x1016 ions/cm2 and electrolytically etched in a 5% Nital solution at 5V for 20 seconds. The etched sample was then examined using a JEOL JSM25S scanning electron microscope.
