    Abstract

    This paper represents a response to the CSNI Ad Hoc Group standard problem program. The USAEC Standard Problem One for blowdown (the Edwards and O'Brien single pipe blowdown) has been considered. The calculations were performed on Burroughs B6700 by the program TPD3. This program features individual mass conservation equations for the phases and the consideration of thermal non-equilib-'um for the water. The USAEC prescribed "adjusted" initial
    temperature distribution led to an underprediction of the pressure after the expansion wave. A second calculation was therefore performed using the initial temperature measured and reported by Edwards and O'Brien. The result of this second calculation shows good agreement with the measured pressure response.
