AUTOMATED ANALYSIS OF MULTIPLE THERMAL TRANSIENT SETS FOR NUCLEAR PIPING.

Abstract

Thermal transient analysis of nuclear class 1 piping requires considerable training, experience and judgment on the part of engineers. The analysis exercise is even more involved when the single piping model consists of piping from many process systems, and correspondingly multiple transient sets are specified. The approach using the available commercial computer programs is time-consuming as well as subject to human errors. In Ontario Hydro, we have developed a complete thermal transient analysis program which is highly automated, and requires much less effort of the design engineers. The manhours are significantly reduced while each analysis is performed consistently, accurately and is more in accordance with quality assurance programs. This paper presents technical details on the automated analysis of multiple transient sets. This feature of the program is illustrated via an example.
