	N-BASE - The threats at Dounreay
		The Dounreay Nuclear Establishment near Thurso on the north coast of Scotland was chosen in the 1950s as the centre for the UK's fast breeder reactor programme - a new type of reactor, fuelled by plutonium.
		Dounreay was chosen because it was isolated and away from large centres of population.
		With the closure of the PFR reactor in 1994 Dounreay began its busiest-ever reprocessing programme.

		Fast neutron reactors have a high power density and are normally cooled by liquid metal such as sodium, lead, or lead-bismuth, with high conductivity and boiling point and no moderating effect.
		A full-scale prototype fast reactor is envisaged by 2020, and CNNC expects the technology to become predominant by mid century.
		Cooling of the fast reactor core requires a heat transfer medium which has minimal moderation of the neutrons, and hence liquid metals are used, typically sodium or a mixture of sodium and potassium.

		Parties of visitors trooped diligently round the narrow walkway that surrounded the reactor, trying to take in everything their technician guides told them about this exciting new scientific development, which was to be used to unlock the innermost secrets of materials which might prove useful to medicine, industry and, of course, nuclear power reactors.
		Fast reactors are no longer new, in fact some regard them as a scientific anachronism, an expensive blind alley whose exploration squandered vast amounts of valuable intellectual and financial resources.
		Not one of its three reactors has been fully decommissioned; many plants in the fuel cycle area are still operational; improved methods are continually being applied to the handing and storage of radioactive waste; and there is, of course, the small task of emptying the waste shaft and the silo...

	N-Base Briefing 59
		Dounreay has responded to the UK Government's decision definitely to close its PFR fast reactor in 1994 with the start of an aggressive campaign to increase its reprocessing work.
		Dounreay claims it has signed only nine reprocessing contracts for foreign research reactor fuel and senior management has warned that a "purely commercial" decision on the plant's future will have to be taken next month.
		The reactor was shut in June 1991, only a few months after another lengthy closure for repairs, because problems with a filter resulted in oil leaking into the 1000 tonnes of liquid sodium used to cool the reactor core.

		This is the Dounreay Fast Reactor, the first fast breeder reactor to produce electricity for the national grid.
		The reactor was constructed between 1955 and 1958 and until its closure in 1977, it played an important part in the world’s fast reactor research by developing fuel designs, coolant technology, efficient reprocessing and nuclear waste management.
		DFR demonstrated that a safe and easily operable fast reactor could be built on the scale required for power station use.

	Highland archives:Dounreay 1954 - The Fears and The Facts
		Dounreay was chosen chiefly because of the assumed risk that, in the event of a catastrophic control system failure leading to core meltdown, a release of radioactivity to the environment was a likely consequence.
		Assuredly, Donald Carmichael was early made aware of the risks associated with the fast reactor; a pragmatic man of the world, well acquainted with the wider facts of life, he accepted these risks and had faith in the great abilities of the engineers who had designed the reactor.
		Sir David's speech is a masterpiece of tub-thumping triumphalism, in which he stated, with some justification, that had he not been the area's MP the fast reactor project would never have come to Caithness.

	Dounreay
		A second nuclear reactor, the Prototype Fast Reactor (PFR), was active between 1974 and 1994.
		The Dounreay site had caused offshore contamination in the 1960s and 1970s as used nuclear fuel was cropped in a machine that generated radioactive particles.
		In 1996 a radioactive leak in the main dissolver in the reprocessing plant made the plant inoperable, and in 2001 a decision was taken to begin the decommissioning of the nuclear reprocessing plant.

	Fast breeder reactor Summary
		On December 20, 1951, the fast reactor EBR-I (Experimental Breeder Reactor-1) at the Idaho National Engineering and Environmental Laboratory in Idaho Falls, Idaho produced enough electricity to power four light bulbs, and the next day produced enough power to run the entire EBR-I building.
		At present the scientists of the Indira Gandhi Centre for Atomic Research (IGCAR), one of the nuclear RandD institutions of India, are engaged in the construction of another FBR - the 500 MWe prototype fast breeder reactor- at Kalpakkam, near Chennai.
		One design of fast neutron reactor, specifically designed to address the waste disposal and plutonium issues, was the Integral Fast Reactor (also known as an Integral Fast Breeder Reactor, although the original reactor was designed to not breed a net surplus of fissile material) [4] [5].

	Fast neutron reactors (FBR) - Encyclopedia of Earth
		In fast neutron reactors, most fission reactions are generated by neutrons with energy levels of the same order of magnitude as when they were produced by fission.
		Sometimes loosely referred to as "fast" reactors, they accept a wider variety of fuel isotopes than pressurized water reactors at the cost of a higher neutron flux in the reactor, and a high concentration of fissile isotopes in the fuel.
		A full-scale prototype fast reactor is envisaged by 2020, and the China National Nuclear Corporation (CNNC) expects the technology to become predominant by mid-century.

		The path that was eventually to lead to establishing Dounreay as the centre for Britain’s fast reactor development programme was long and winding yet, paradoxically, it was achieved in a relatively short time.
		Every aspect of the reactor design was scrutinised, and despite the careful wording of the minute-taker, it is very clear there were many heated debates and that little went through ‘on the nod’, recommendations were frequently challenged and the authors invited to re-visit their conclusions.
		As their understanding of fast reactor technology grew, their fears of an explosion diminished, although they never dismissed the possibility, or the danger associated with a release of radiation.

		But the Dounreay dome could vanish from the horizon forever after claims that the building, which many had hoped would acquire listed status, will be too expensive to maintain after it is decommissioned.
		The Dounreay reactor was completed in 1958 and operated from 1959 to 1977.
		I recognise that it was not all benefits that came with the Dounreay reactor but it had an important place in the area's past, and retaining the dome would be a memento of that - as well as a memento of the fact that it is an iconic building in its own right.

	MOX FUEL MANUFACTURE AT SELLAFIELD
		Associated fuel irradiation programmes carried out in the Dounreay Materials Testing Reactor, the Dounreay Fast Reactor and the Prototype Fast Reactor (PFR) were used to assess the influence of fuel properties such as density, fuel form and chemical composition on irradiation performance.
		Following the Government's decision in 1988 to end the fast reactor programme, UKAEA and BNFL decided to collaborate in the development of a process to develop the use of MOX fuel to recycle separated plutonium in light water reactors.
		The building was originally owned and operated by UKAEA to support the Dounreay Fast Reactor Project, providing the experimental fuel for the Prototype Fast Reactor.

		In particular, in order to make a penetration of the reactor vault, it was necessary to undertake extensive surveys of existing services (electrical, liquids, HVAC and C&I), validate their safety functional requirements, (since DFR was still under operational safety control), and to design services and C&I diversions.
		Many of the services to be provided for the original concept were safety critical and included cooling plants, air handling and filtration systems, back-up generators, electrical controls, electronic interlocks, radiation detection equipment, fire suppression equipment and a range of process plant for NaK passivation, neutralisation of liquors, ion exchange, decontamination and waste packaging.
		However, project costs were significantly in excess of the sanctioned budget, which led to a detailed technical challenge of the initial concept involving; review of user requirements, assessment of overall DFR programme implications and opportunities for technical innovations.
