A numerical analysis has been performed to estimate the effect of thermal stratification in the safety
injection system piping lines. This phenomenon of thermal stratification is usually observed in the piping
lines of the safety injection system that is connected high pressure and high temperature system as well
as this system is isolated by isolation valve normally.
This piping lines may be identified as the source of fatigue in the piping system due to the thermal
stress loading which are associated with plant operating modes. The turbulent penetration length,
generally, reaches to 1^st isolation valve in safety injection system piping from reactor coolant system at
normal power operation when a high temperature coolant does not leak out through 1^st isolation valve. At
that time, therefore, the thermal stratification does not appear in the piping between RCS piping and 1^st
isolation valve of safety injection system piping.
When a high temperature coolant leak out through the 1^st isolation valve by any damage of isolation
valve, however, the thermal stratification can occur in the safety injection system piping. At that top and
bottom leakage, the maximum temperature difference of fluid between top and bottom in the piping is,
respectively, estimated about 20 and 27℃. But the thermal load and potential for branch pipes is
considered insignificant, since the maximum temperature difference is less than 27.8℃(maximum
potential temperature difference). Therefore, it is considered that this will be ignored the effect of thermal
stratification in safety injection system piping with valve leakage.
