ESDU Nuclear Plant Thermo-hydraulic Design

Validated data, procedures and software, endorsed by Professional Institutions, are provided for the use in the thermo-hydraulic design, safety assessment and maintenance/operation of nuclear facilities. The information presented in this Segment can be used in plants where fluids through pipe networks and heat transfer equipment is pumped and handled to, for example:

• Select equipment such as pumps, fans and heat exchangers
• Design and assess jet pumps for liquid, gas and steam flows
• Design, select or restore heat exchangers including economic considerations
• Optimize Heat Exchanger networks
• Calculate pressure losses in equipment handling liquids, gases and mixed liquid-gas fluids
• Calculate transient effects in pipelines including water hammer for liquids

Methods and data are given for use by the plant engineer, design engineer or consultant in the day- to- day evaluation of fluid flow through various piping systems. Hand calculation methods and computer programs based on empirically-derived correlations and numerical methods provide rapid and reliable estimates of fluid flow parameters. The limits of applicability are stated and guidance is given on the maximum tolerance to be allowed on the predictions.

Data are provided for use by design engineers or consultants dealing with the evaluation or prediction of the performance of heat transfer equipment and the costing of heat exchangers. The data give step-by-step calculation methods and indicate the limits of applicability and the limits of accuracy of empirical correlations.

Correlated data, based on reliable measurements, are provided for the fluid physical properties of a wide range of pure compounds and some mixtures as equations and in tabular form.
