Pulsed Columns
Pulsed columns are a type of liquid-liquid extraction equipment; examples of this class of extraction equipment is used at the BNFL plant THORP ''Thorp'' is a Middle English word for a hamlet or small village. Etymology The name can either come from Old Norse ''þorp'' (also ''thorp''), or from Old English (Anglo-Saxon) ''þrop''. There are many place names in England with the suffi .... Special use in nuclear industries for fuel reprocessing, where spent fuel from reactors is subjected to solvent extraction. A pulsation is created using air by a pulse leg. The feed is aqueous solution containing radioactive solutes, and the solvent used is TBP (Tri-Butyl Phosphate) in suitable hydrocarbon. To create turbulence for dispersion of one phase in other, a mechanical agitator is used in conventional equipments. But, because of radioactivity, and frequent maintenance required for mechanical agitators, pulsing is used in extraction columns. References Chemical equipment ...

BNFL
British Nuclear Fuels Limited (BNFL) was a nuclear energy and fuels company owned by the UK Government. It was a manufacturer of nuclear fuel (notably MOX), ran reactors, generated and sold electricity, reprocessed and managed spent fuel (mainly at Sellafield), and decommissioned nuclear plants and other similar facilities. It was created in February 1971 from the de-merger of the production division of the UK Atomic Energy Authority (UKAEA). Until 2003, its headquarters were at Risley, near Warrington, England. BNFL's headquarters were then moved to Daresbury Park industrial estate, also near Warrington. On 1 April 2005, BNFL formed a new holding company and started a rigorous restructuring process which would transfer or sell most of its entire domain, divisions. In 2005, it transferred all of its nuclear sites to the Nuclear Decommissioning Authority. It then sold its Westinghouse Electric Company subsidiary in February 2006.

THORP
''Thorp'' is a Middle English word for a hamlet or small village. Etymology The name can either come from Old Norse ''þorp'' (also ''thorp''), or from Old English (Anglo-Saxon) ''þrop''. There are many place names in England with the suffix "-thorp" or "-thorpe". Those of Old Norse origin are to be found in Northumberland, County Durham, Yorkshire, Lincolnshire, Cambridgeshire, Norfolk, and Suffolk. Those of Anglo-Saxon origin are to be found in southern England from Worcestershire to Surrey. Care must be taken to distinguish the two forms. Variations of the Anglo-Saxon suffix are "-throp", "-thrope", "-trop" and "-trip" (e.g. Adlestrop and Southrope). Old English (Anglo-Saxon) ''þrop'' is cognate with Low-Saxon ''trup''/''trop''/''drup''/''drop'' as in Handrup or Waltrop, Frisian ''terp'', German ''torp'' or ''dorf'' as in Düsseldorf, the 'Village of the river Düssel', and Dutch ''dorp''. It also appears in Lorraine place-names as ''-troff'' such as Grosbliederstr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
