=== Article of the Week <font size=1>[ [[CZ:Article of the Week|about]] ]</font> ===
'''[[Lead]]''' is a [[chemical element]]. It is a [[heavy metal]], and is abundant in nature.  Lead has the symbol Pb (from the Latin Plumbum).  Its [[atomic number]] is 82. Lead is a very corrosion-resistant, dense, ductile, and malleable blue-gray metal that has been used for at least 5,000 years.


Early uses of lead included building materials, [[pigments]] for [[glazing]] [[ceramics]], and [[pipe]]s for transporting water.  Prior to the early [[1900's]], uses of lead were primarily for [[ammunition]], [[brass]], burial vault liners, ceramic glazes, [[leaded glass]] and [[crystal]], [[paint]]s or other protective coatings, [[pewter]], and water lines and pipes. The advent of the [[electricity|electrical age]] and [[Communications Age|communications]], which were accelerated by technological developments in [[World War I]], resulted in the addition of [[bearing metals]], cable covering, [[caulking]] lead, [[solder]]s, and type metal to the list of lead uses.  With the growth in production of [[Automobile|public and private motorized vehicles]] and the associated use of starting-lighting-ignition (SLI) [[lead-acid storage batteries]] and [[terne metal]] for gas tanks after World War I, demand for lead increased.  Later, [[radiation shielding]] in [[Radiography|medical analysis]] and [[Television|video display equipment]] and as an [[Tetraethyl Lead|additive in gasoline]] also increased usage.

Although bound up with the tradition of the ‘special library’, '''[[Information Management|information management]]''' differs from such earlier concepts in its focus on all kinds of information and a concern for the relationship between information provision and organizational performance. In many special libraries there had long been responsibility for managing internal documentation of various kinds, especially research reports. The history of this development is usefully explored by Black, Muddiman and Plant [1] who note the emergence of information management concepts following the end of the First World War, with the formal organization of ‘information bureaux’ in the establishment of ASLIB (the Association of Special Libraries and Information Bureaux) in the UK in 1924. Some techniques, however, were even older, witness Kaiser’s work on indexing [2][3]. Indeed, we can date many of the ideas of what is now called ‘information management’ (although ‘documentation’ is used as a near equivalent in much of Europe) to the founding by Otlet and La Fontaine of the International Institute of Bibliography in 1895

Featured Article: Nuclear power reconsidered

After decades of failure to slow the rising global consumption of coal, oil and gas,[1] many countries have proceeded as of 2024 to reconsider nuclear power in order to lower the demand for fossil fuels.[2] Wind and solar power alone, without large-scale storage for these intermittent sources, are unlikely to meet the world's needs for reliable energy.[3][4][5] See Figures 1 and 2 on the magnitude of the world energy challenge.

Nuclear power plants that use nuclear reactors to create electricity could provide the abundant, zero-carbon, dispatchable[6] energy needed for a low-carbon future, but not by simply building more of what we already have. New innovative designs for nuclear reactors are needed to avoid the problems of the past.

Fig.1 Electricity consumption may soon double, mostly from coal-fired power plants in the developing world.[7]

Issues Confronting the Nuclear Industry

New reactor designers have sought to address issues that have prevented the acceptance of nuclear power, including safety, waste management, weapons proliferation, and cost. This article will summarize the questions that have been raised and the criteria that have been established for evaluating these designs. Answers to these questions will be provided by the designers of these reactors in the articles on their designs. Further debate will be provided in the Discussion and the Debate Guide pages of those articles.

Footnotes

  1. Global Energy Growth by Our World In Data
  2. Countries, organizations, and public figures that have reconsidered their stance on nuclear power are listed on the External Links tab of this article.
  3. Pumped storage is currently the most economical way to store electricity, but it requires a large reservoir on a nearby hill or in an abandoned mine. Li-ion battery systems at $500 per KWh are not practical for utility-scale storage. See Energy Storage for a summary of other alternatives.
  4. Utilities that include wind and solar power in their grid must have non-intermittent generating capacity (typically fossil fuels) to handle maximum demand for several days. They can save on fuel, but the cost of the plant is the same with or without intermittent sources.
  5. Mark Jacobson believes that long-distance transmission lines can provide an alternative to costly storage. See the bibliography for more on this proposal and the critique by Christopher Clack.
  6. "Load following" is the term used by utilities, and is important when there is a lot of wind and solar on the grid. Some reactors are not able to do this.
  7. Fig.1.3 in Devanney "Why Nuclear Power has been a Flop"
