ParametersValue/definitionRemarks

Circumferential scale of the test section to prototype1 : 100
Radial scale of the heating section to the prototype RPV1 : 1With the same outer diameter as the as the prototype RPV lower head
Height scale of the natural circulation loop to the prototype RPF system1 : 1
