The key components common to most types of nuclear power plants are:

(Penulis sedang "Nyengirrr" he.,he.,, cakep juga ya? Wkwkwk.,.(Readers: "Kepedean tuh mas"))

Nuclear power is produced by controlled (i.e., non-explosive) nuclear reactions. Commercial and utility plants currently use nuclear fission reactions to heat water to produce steam, which is then used to generate electricity. In 2009, 13-14% of the world's electricity came from nuclear power.[1] Also, more than 150 naval vessels using nuclear propulsion have been built.

 (Mr. Angga Fuja W.)

The economics of new nuclear power plants is a controversial subject, since there are diverging views on this topic, and multi-billion dollar investments ride on the choice of an energy source. Nuclear power plants typically have high capital costs for building the plant, but low fuel costs. Therefore, comparison with other power generation methods is strongly dependent on assumptions about construction timescales and capital financing for nuclear plants. Cost estimates also need to take into account plant decommissioning and nuclear waste storage costs. On the other hand measures to mitigate global warming, such as a carbon tax or carbon emissions trading, may favor the economics of nuclear power.

Here is a list of all the topics available from the Beginner's Guide to Rockets web site. Clicking on the title will deliver a page with a slide and a scientific explanation of the contents. Pages containing "Animated" graphics, or "Interactive" calculators and graphics, are noted in red. "Simulation" pages are also noted in red and contain Java applets which solve the equations described on other pages at the site.. If the number and variety of pages seems too intimidating, consider taking one of our Guided Tours through the web site. 

Another method for reaching students, teachers and lifelong learners is the use of Distance Learning. While preparing presentations for students, many Power Point files have been developed for the Digital Learning Network

using information from the BGR. Students and teachers are encouraged to copy the Power Point files to their own computers and to modify them as desired for their own presentations.

Frontiers and Controversies in Astrophysics

Lecture 23 - Other Constraints: The Cosmic Microwave Background


Reasons for the expansion of the universe are addressed at the start of this lecture, focusing especially on the acceleration of dark energy. Supernovae were the first evidence for the existence of dark energy. Two other proofs are presented. The first is the Cosmic Microwave Background, which is a form of electromagnetic radiation that is perfectly smooth and equal in all directions. It firmly supports the Big Bang theory. Projects attempting to measure it, such as COBE and WMAP, are discussed. Secondly, Large-Scale Clustering is introduced: by measuring the degree of clustering, astronomers hope to advance their understanding of dark energy and dark matter. Computer simulations of the evolution of the universe are shown.
