Generation What?

Note: this is an updated version of an older post.

Below is a quick rundown of most of the reactors being marketed as of early 2012.  I'm using the term "marketed" somewhat loosely here, as not all reactors are being offered in all countries due to intellectual property rights, nationalism, or other considerations.  I have ignored a number of small reactor designs that I feel are just vaporware at this point.  The three small PWRs plus the ten of other types account for over half of the 24 models, but medium-large (for lack of a better term) PWRs such as the AP1000 have captured the overwhelming majority of the orders.

An oddity to note is that Westinghouse no longer markets a PWR derived from the ones it created in the 1960s due to a series of corporate mergers.  But the basic Westinghouse design lives on in the EPR, APWR, Amtea1 and CPR-1000 designs.  Westinghouse, which is 77% owned by Toshiba, now offers reactors derived from Combustion Engineering designs.  A minor point to note is that both GE-Hitachi and Toshiba are both marketing the ABWR.

By neutron speed, there are:
By major type, there are:
By design family, there are:
  • 4 Westinghouse (WH) pressurized water reactors
  • 4 Combustion Engineering (CE) pressurized water reactors
  • 4 GE boiling water reactors
  • 3 VVER pressurized water reactors (Russian PWRs evolved separately from western designs)
  • 3 CANDU heavy water-moderated reactors
  • 1 B&W small pressurized water reactor (probably derived from US Navy designs, may be new)
  • 1 KLT-series small pressurized water reactor (evolution of Russian Navy designs)
  • 1 BN-series sodium-cooled fast reactor (designed by a state-owned organization in Russia)
  • 1 new small pressurized water reactor (stated as being derived from the AP1000, but so small that it's probably all new)
  • 1 new small lead-bismuth-cooled fast reactor (probably a new design)
  • 1 new small sodium-cooled fast reactor (probably a new design) 
By generation, there are:
  • 12 "Generation III" designs (designs from the 1990s and 2000s with some passive safety features)
  • 8 "Generation II+" designs (slight improvements over 1960s designs)
  • 2 "Generation II" designs (basically 1960s designs)
  • 2 designs I haven't classified because I lack familiarity with them
The term "generation" was introduced by the DOE several years ago in order to simplify the presentation of its strategy.  Right now it is pursing two goals: building evolved PWRs and BWRs (the Gen III models), and doing R&D on "Generation IV" reactors.  The marketing types have hijacked the nomenclature a bit, and have labeled some reactors "III+" as well as backfitted the "II+" designation on others.  I've ignored the III+ designation, but the II+ designation is not unreasonable because the designs have been worked on since they were first developed in the 1960s.

Note: the PHWR-700 is not being marketed per say, but it is the current standard domestic plant for India, and there are several examples under construction.
