found: British Energy WWW site, Aug. 2, 2006:about British Energy/education/different types of reactor (A fast reactor core, since it has no moderator, is very compact ... and therefore has a high power density. It is usually cooled by liquid sodium, which is very efficient at removing heat ... It also has the very attractive safety feature that it can maintain cooling by natural convection should cooling pumps fail)
