    Energy accounting in nuclear power systems
    (Australian Atomic Energy Commission., 1975-10) Symonds, JL; Essam, P; Stocks, KJ
    Energy analysis is a systematic way of tracing and accounting for the flows of energy through an industrial system and apportioning a quantity of the primary energy input to each of the goods and services sent out. The application of energy accounting to nuclear power stations and their growth in generating systems is discussed. Misunderstandings arising from discrepancies and weaknesses in some published simple analyses of hypothetical growth situations are outlined. Results of a more complex energy flow analysis are used to demonstrate that current nuclear energy programs are running at an energy profit. Large fossil fuel savings will occur in a real electrical grid system under anticipated nuclear power growth rates. These savings will give a new dimension in planning the use of fossil energy resources which will still be needed for transport and industrial processes, such as steel-making, for some time to come.

    Net fossil energy savings for alternative mixes in various electric supply systems.
    (Australian Atomic Energy Commission, 1978-11) Essam, P
    Actual and projected electric power station building programs of several countries and regions have been examined to determine what effect the introduction of nuclear power has on fossil fuel usage by the electricity system. It was found that (i) nuclear power leads directly to savings in fossil fuel usage, a larger nuclear component leading to larger savings; (ii) individual nuclear stations rapidly wipe out the energy 'debt' incurred during building; and (iii) the relatively short periods of consolidation in the early stages of a nation's building program usually prevent the nuclear component from going into energy 'debt'. Assessments of the energy requirements to build and run various types of power station have been made from the available literature.
