Highly radioactive liquid, known as raffinate, has been stored in tanks for around 20 years after being produced as a by-product of Prototype Fast Reactor
(PFR) fuel reprocessing.
In an attempt to retrieve pieces of radioactive metal from the inside of the station's Prototype Fast Reactor
, staff resorted to using Blu-Tack attached to a 10-metre-long pole to fish out the material, the BBC reported.
Workers at Dounreay, near Thurso, in Caithness, had to take samples of metal from holes drilled into the base of the Prototype Fast Reactor
It broke out in October in the prototype fast reactor
The fire broke out on October 7 in the prototype fast reactor
sodium tank building, where sodium residues from the operation of the reactor are stored.
There have been several demonstration fast reactors developed, including the Dounreay Fast Reactor (DFR) and Prototype Fast Reactor
(PFR), and others include designs in France, Russia, Japan and the US.
To date, the government has undertaken various activities toward FBR development, including the achievement of an experimental fast reactor "Joyo" (initial criticality in 1977) and of a prototype fast reactor
"Monju" (criticality in 1994).
The pair spent about seven minutes on their abortive search for the visitor centre before they spoke to a workman outside the entrance to the site's prototype fast reactor
To calculate the damage due to discharges into the atmosphere, the inventory of tritium of the Prototype Fast Reactor
(PFR) was considered as the upper limit and applied to the DFR NaK for a period of 12 months.
The first 'fast reactor' was started in 1962, and in 1975 the revolutionary Prototype Fast Reactor
The succeeding decades saw construction and operation of experimental and prototype fast reactor
facilities in the US, the Soviet Union, the United Kingdom, France, Germany, Japan and India.
When the prototype fast reactor
(PFR) at Dounreay was shut down in 1994 the question I asked was "how long would it be before we would be buying designs of similar reactors from the US, Taiwan or Japan?
