    Behaviour of particles of U, UO2, and UC2 in a vertical tube through which liquid sodium is flowing
    (Australian Atomic Energy Commission, 1956-06) Berglin, CLW
    This paper sets out to calculate the relation between the particle velocity and the fluid velocity in a vertical tube without making any assumptions as to the "apparent" viscosity of the suspension of particle in liquid sodium. The theory and calculations method is developed for suspensions of U, UO2 and UC2 in liquid Na in the temperature range 200º - 800ºC. At the moment, it does not help in assessing the performance of a circulating suspension in the primary coolant stream of nuclear power reactor.

    Preliminary design of annular tube heat exchangers for circulating fuel systems
    (Australian Atomic Energy Commission, 1957-02) Berglin, CLW
    This paper follows up one of the suggestions in AAEC-E-2, and shows that the annular tube heat exchanger for circulating fuel systems is practical, compact and has a reasonable out-of-core holdup.

    Relative holdup of heat exchanges for circulating fuel systems.
    (Australian Atomic Energy Commission, 1958-06) Berglin, CLW; Sodium
    This report sets out the relative holdup for tube type heat exchangers of sodium-uranium suspension and bismuth-uranium solution systems for various sizes of tube and tube wall thickness. It shows that based on a temperature difference of 50ºc the holdup in the heat exchanger for the sodium-uranium suspension is at least 6 times that for the bismuth-uranium solution and as a conservative estimate may be taken as 8 times. A table is included of the leading dimensions of heat exchangers or a heat load of 500 MW with tubes of 3/4" and 1" outside diameter respectively.

    Suggestions for work on design of heat exchangers in liquid metal fueled reactors
    (Australian Atomic Energy Commission, 1956-06) Berglin, CLW
    The report discusses the low heat transfer film coefficient on the secondary coolant side of tubular exchangers used in the calculations in AAEC-E-1. It suggests the types of heat exchangers which should be investigated in order to improve this coefficient and in turn to reduce the relative hold-up.
