• Short Summary

    The Douneray Establishment centres around the experimental fast fission reactor enclosed in its massive 135 ft retaining sphere.

  • Description

    Reel I. 320 ft. Plus X. Exteriors scenes around Douneray.

    General view from above the Fast Fission Breeder Reactor.

    Board outside the Establishment - etc.

    Shot through rails of dome of Breeder Reactor, etc.

    Pan shot from the Fast fission Reactor to the Douneray Materials Testing

    Reactor, the D.M.T.R.

    Shots of the D.M.T.R. along pipelines.

    Shot of giant dome of Fast Fission Reactor.

    Seascapes - pan to the D.M.T.R.

    Seascapes from where the sea water is taken in for cooling - pan to dome of F.F.B.R.

    Rough seas, etc.

    Buildings where Fuel Elements are made and processed - men arriving, etc.


    The D.M.T.R. Fuel Element Plant will supply fuel elements not only for the heavy water moderated test reactor at Douneray, but also for two similar reactors at HARWELL and for other reactors of this type both in this country and overseas.

    General view of the operating line where a number of operations take place with the operator protected through screens and where handling is done through these screens.

    Close shots of operator weighing a uranium alloy billet.

    After further stages the billet is placed in a furnace and heated to 950 C.

    Shots of man handling furnace.

    At a later stage the billet is rolled. The uranium is now clad in aluminium and the operators can work within the room.

    Next comes the Fuel Element Box assembly, where 10 of the plates are assembled separated by aluminium spacing pieces. Various angles on assembly with spacers and plates being checked.

    Lastly is the final assembly. Here we see the Tube Sub Assembly being fitted

    After the final assembly the complete Fuel Element is dipped into chemicals for cleaning. An element is seen being lowered into chemicals.

    REEL THREE. Tri-X. 400'.

    The finished Fuel Element is placed in a polythene bag and this is then inserted in a special aluminium transit container holding 10 elements for shipment to the reactors.This consignment is going to the "HIFAR" reactor is Sydney, AUSTRALIA.

    Next scenes are in the D.M.T.R. Chemical Separation Plant which receives a complete reactor charge of irradiated fuel elements in a shielded 'coffin' from the reactor. This 'coffin' containing 25 elements weighs approximately 20 tons.

    Further shots of 20 tons 'coffin' being manoeuvred into position for discharging the highly active fuel elements into the 'pond'.

    General shot from above the 'pond' into which the highly active fuel element has been discharged. It is then handled with long tongs below the water to be fed into a milling machine, below water, for separating the plates.

    Various angles on handling the fuel element and shots of the element below water.

    These plates are later dissolved in chemical and shots of the element below water.

    These plates are later dissolved in chemical processing to recover the URANYL NITRATE solution (Uranium Nitrate).

    REEL FOUR. Plus X. 120'

    Taking samples of the URANYL NITRATE. These samples are then taken to the Laboratories for analysis.

    Various angles on sampling.

    It has been requested by Mr. ALAN BRAY, P.R.O. at Douneray that we contact:- Mr. STANLEY WHITE, Chief Press Officer, U.K.A.E.A., II Charles II Street, London, S.W.I. Tel. WHItehall 6262 - ext. 331 for 'vetting this material and for assistance with commentary.
    See hand-out (d) for details.
    Neither the D.M.T.R. Fuel Element Plant nor the Materials Testing Reactor Chemical Plant have been filmed before for release to the Public.
    A 'coffin' is seen arriving in the Plant, and being lifted by special giant crane into the Pond area. Shot through window - protective window - from the control face looking into the working area.
    Shots in the control room of the Chemical Plant.
    Next into the working area, near the 'pond' where the giant 'coffin' of 20 tons weight is manoeuvred into position for discharging the fuel elements in to pond.

    Background: The Douneray Establishment centres around the experimental fast fission reactor enclosed in its massive 135 ft retaining sphere. From this reactor will come the necessary operating experience in commissioning an advanced machine, and experimental data on the behaviour of fuel elements, cooling systems and control. To commission and maintain the reactor in operation a Fuel Element plant is required, together with Chemical Processing facilities, to refrabricate the fuel into new elements.

    Our film sequence shows fuel elements being made in the Fuel Element plant and also the Fuel Element Processing Plant where these elements are treated after having being used in a reactor.

    Also at Douneray is the first materials-testing reactor of the Industrial Group and similar types of reactor are at HARWELL where they have two known as "DIDO" and "PLUTO", in AUSTRALIA where in SYDNEY is the "HIFAR" or High Flux Australian Reactor - and in DENMARK, where the "DR3" is installed at RISO.

    Fuel elements for all four of these reactors are produced at DOUNERAY and these elements are also returned to Douneray for processing after use and the fuel refabricated into new elements.
