The Advanced Boiling Water Reactor (ABWR) is an improved design of boiling water reactor. The ABWR was designed by General Electric. A boiling water reactor (BWR) is a light water reactor design used in some nuclear power stations. ... The General Electric Company, or GE, (NYSE: GE) is a multinational technology and services company. ...


One chief improvement is that the recirculation pumps and piping are contained inside the reactor pressure vessel, thus making it impossible for them to leak outside of the vessel. Also, in the event of a loss of coolant accident (LOCA), plant response has been fully automated and operator action is not required for 3 days. These and other improvements make the plant significantly safer than previous reactors. A pressure vessel is a structure designed to contain a fluid at a different pressure to the pressure surrounding the structure without changing volume. ...


As of 2005, three ABWRs were in operation in Japan and two were under construction at Lungmen in Taiwan. One or more ABWRs are proposed for construction in the US under the Nuclear Power 2010 Program. 2005 is a common year starting on Saturday of the Gregorian calendar and is the current year. ... Wikiquote has a collection of quotations by or about: United States Wikinews has news related to this article: United States United States government CIA World Factbook Entry for United States House. ... The Nuclear Power 2010 Program was unveiled by the Secretary of the Department of Energy on February 14, 2002 as one means towards addressing the expected need for new power plants. ...


Safer designs have been proposed but none yet built. Examples include the ESBWR (Economic Simplified BWR), the AP-1000 (Advanced Passive-1000) and the pebble bed modular reactor. The Pebble Bed Reactor is an advanced nuclear reactor design. ...

A MANUFACTURER'S VIEW OF THE AFFLUENT SOCIETY AND THE ROLE OF NUCLEAR ENERGY (2799 words)
Success of ABWR was realized through international cooperation and cooperative relations among the three key parties: the manufacturers, the user and the government.
A major improvement in the ABWR, consistent with the trend of BWR improvement, is that it achieves further simplification of the primary recirculation loop by the adoption of Reactor Internal Pumps(RIP).
Next ABWR will build on the favorable records established by the first units and is expected to start operation in the first half of 2000.
