24Pressurized water reactor — (PWRs) (also VVER if of Russian design) are generation II nuclear power reactors that use ordinary water under high pressure (superheated water) as coolant and neutron moderator. The primary coolant loop is kept under high pressure to prevent the …
25Organically moderated and cooled reactor — The organic moderated and cooled reactor (OCR) was an early power reactor concept studied in the formative years of nuclear power by the United States Atomic Energy Commission and others around the world. The concept reactor was very similar to… …
26Centrifugal compressor — Centrifugal compressors, sometimes termed radial compressors, are a sub class of dynamic axisymmetric work absorbing turbomachinery.[1] Centrifugal impeller with a highly polished surface likely to improve performance …
27Jet engine performance — This article describes how jet engine performance is estimated during the design phase. Similar techniques are used once the engine has been built and is being tested, except the performance of individual components, rather than being assumed, is …
