As the parent of actinium in this series it was named protoactinium, shortened in 1949 to protactinium. Because of its low natural abundance its chemistry was obscure until 1960 when A. G. Maddock and co-workers at the UK Atomic Energy Authority worked up about 130g from 60 tons of sludge which had accumulated during the extraction of uranium from UO2 ores. It is from this sample, distributed to numerous laboratories throughout the world, that the bulk of our knowledge of the element s chemistry was gleaned.

Butex A process for separating the radioactive components of spent nuclear fuel by solvent extraction from nitric acid solution, using diethylene glycol dibutyl ether (also called Butex, or dibutyl carbitol) as the solvent. Developed by the Ministry of Supply (later the UK Atomic Energy Authority) in the late 1940s. Operated at Windscale from 1952 until 1964 when it was superseded by the Purex process. 

HARVEST [Highly Active Residue Vitrification Experimental Studies] A process for immobilizing nuclear waste by incorporation in a borosilicate glass. Developed from FIN-GAL. Piloted by the UK Atomic Energy Authority at Sellafield, in the late 1970s, but abandoned in 1981 in favor of AVM, the French vitrification process. 

LOMI [Low oxidation metal ions] A process for decontaminating parts of nuclear reactors by washing with aqueous solutions of low-valency transition metal ions. Developed at the Berkley laboratories of the UK Atomic Energy Authority in the early 1980s. 

FINGAL [Fixation IN Glass of Active Liquors] A batch process for immobilizing nuclear waste in a borosilicate glass. Developed by the UK Atomic Energy Authority at Harwell from 1958 and piloted at its Windscale Works from 1962 to 1966. After a lapse of several years, the project was resumed in 1972 under the acronym HARVEST. 

First identified in 1913 (the first compound, Pa20s, was isolated in 1927 by von Grosse, who isolated the element in 1931), protactinium is not generally extracted. Most of what is known about the chemistry of protactinium ultimately results from the extraction in 1960 by the UK Atomic Energy Authority of some 125 grams of Pa, from 60 tons of waste material left over from the extraction of uranium, at a cost of about 500,000 (very roughly, 1,250,000 at today s exchange rate).

One radioactive plume crossed the English Channel into southern England in the early hours of 2 May, having experienced almost no rain on its tortuous 4100 km track from Chernobyl. Measurements of related activity in the air were made by the Electricity Boards, by British Nuclear Fuels pic, by the UK Atomic Energy Authority and by the National Radiological Protection Board at various sites throughout the UK. The Meteorological Office combined these with air-trajectory analyses to define the subsequent movement... 

Two years ago an experiment was carried out by the UK Atomic Energy Authority on the Prototype Fast Reactor at Dounreay, to establish whether ultrasonic imaging could be carried out beneath the sodium. The success of this experiment has given confidence in the eventual use of ultrasonics for under sodium inspection. Under-soUium ultrasonics cannot as yet match inspection techniques that can be applied in a more amenable situation. However it seems likely that it can provide the equivalent of visual examinations.
