- •
A small size, closed experimental loop has been designed and built.
- •
The diameter of loop equals to average hydraulic diameter of sub-channels of HPLWR.
- •
The TH of natural circulation in supercritical water was investigated by the loop.
- •
Interesting trends in steady state characteristic and pressure drop have been shown.
- •
Driving force behind decrease of the neutron attenuation is decreasing water density.
