This photo shows a stainless-steel vessel (1V3) for heavy water storage during maintenance shutdown work.
Stainless pipes are used for any heavy water, whereas green pipes are used for cooling water.
The orange motor is used to circulate heavy water during a reactor shutdown.
Stainless pipes always distribute helium and heavy water to prevent degradation and contamination.
