Analysis Tool for Predicting Transient Hydrodynamics in Nuclear Piping Systems Containing Swing Check Valves

摘要

An analysis tool is constructed for the purpose of predicting the fluid transient in a piping system as a consequence of (or in site of) a check valve being present in the system. The development of the check valve model along with its implementation into a fluid flow analysis computer program is documented. The analysis tool requirements are outlined and the valve flow and disk dynamics are established. A sample demonstration problem was run using the analysis tool and the results reported. Several supporting documents for the transient fluid flow analysis computer program are also included in the appendices. (ERA citation 05:003071)
