On Piping Systems Stress Analyses
Developing piping systems stress analyses is
an important task in the design of nuclear and
non-nuclear facilities. In the last three years,
several analyses were conducted, such as: (i)
IEA-R1 primary stress analysis; (ii) IEA-R1 pri-
mary system support stress analysis; (iii) steam
piping systems subjected to steam hammer
loadings (see Figures 18 to 21)
