reactor  


      n  
1      (Chem)   a substance, such as a reagent, that undergoes a reaction  
2       short for       nuclear reactor  
3    a vessel, esp. one in industrial use, in which a chemical reaction takes place  
4    a coil of low resistance and high inductance that introduces reactance into a circuit  
5      (Med)   a person sensitive to a particular drug or agent  


advanced gas-cooled reactor  
      n   a nuclear reactor using carbon dioxide as the coolant, graphite as the moderator, and ceramic uranium dioxide cased in stainless steel as the fuel,   (Abbrev.)    AGR  
boiling-water reactor  
      n   a nuclear reactor using water as coolant and moderator, steam being produced in the reactor itself: enriched uranium oxide cased in zirconium is the fuel,   (Abbrev.)    BWR  
breeder reactor  
      n   a type of nuclear reactor that produces more fissionable material than it consumes  
   Compare       converter reactor  
  
See also  
    fast-breeder reactor  
converter reactor  
      n   a nuclear reactor for converting one fuel into another, esp. one that transforms fertile material into fissionable material  
   Compare       breeder reactor  
fast-breeder reactor  
      n   a nuclear reactor that uses little or no moderator and produces more fissionable material than it consumes  
   See also       breeder reactor       fast reactor  
fast reactor  
      n   a nuclear reactor using little or no moderator, fission being caused by fast neutrons  
fission reactor  
      n   a nuclear reactor in which a fission reaction takes place  
fusion reactor  
      n   a nuclear reactor in which a thermonuclear fusion reaction takes place  
gas-cooled reactor  
      n   a nuclear reactor using a gas as the coolant. In the Mark I type the coolant is carbon dioxide, the moderator is graphite, and the fuel is uranium cased in magnox  
   See also       advanced gas-cooled reactor  
heavy-water reactor  
      n   a nuclear reactor that uses heavy water as moderator  
magnox reactor  
      n   a nuclear reactor using carbon dioxide as the coolant, graphite as the moderator, and uranium cased in magnox as the fuel  
nuclear reactor  
      n   a device in which a nuclear reaction is maintained and controlled for the production of nuclear energy,   (Sometimes shortened to)    reactor     (Former name)    atomic pile      See also       fission reactor       fusion reactor  
pressurized-water reactor  
      n   a nuclear reactor using water as coolant and moderator at a pressure that is too high to allow boiling to take place inside the reactor. The fuel is enriched uranium oxide cased in zirconium,   (Abbrev.)    PWR  
steam-generating heavy-water reactor  
      n   a nuclear reactor using heavy water as the moderator, light water (H2O) as the coolant, and uranium oxide cased in zirconium alloy as the fuel,   (Abbrev)    SGHWR  
thermal reactor  
      n   a nuclear reactor in which most of the fission is caused by thermal neutrons
