    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.

    FURES - a computer code for system energy flow analysis.
    (Australian Atomic Energy Commission, 1976-10) Faulkner, JI; Stocks, KJ
    A computer code for the analysis of energy flows in an electricity generating system is described. Account is taken of the energy investment in new generating plant as well as the annual energy requirements to provide fuel. Time delays are introduced to place the demands when they occur. All energy inputs are divided into thermal and electrical components. The program can handle a mix of station types which may be conventional and/or nuclear.

    Regression analysis of nuclear plant capacity factors
    (Australian Atomic Energy Commission, 1980-07) Stocks, KJ; Faulkner, JI
    Operating data on all commercial nuclear power plants of the PWR, HWR, BWR, and GCR types in the Western World are analysed statistically to determine whether the explanatory variables size year of operation vintage and reactor supplier are significant in accounting for the variation in capacity factor. The results are compared with a number of previous studies which analysed only United States reactors. The possibility of specification errors affecting the results is also examined. Although in general the variables considered are statistically significant they explain only a small portion of the variation in the capacity factor. The equations thus obtained should certainly not be used to predict the lifetime performance of future large reactors.
