Table 2

Key parameters of REVECT test section.

Parameters	Value/definition	Remarks
Circumferential scale of the test section to prototype	1 : 100
Radial scale of the heating section to the prototype RPV	1 : 1	With the same outer diameter as the as the prototype RPV lower head
Height scale of the natural circulation loop to the prototype RPF system	1 : 1
Number of independent heating zones	23	Cover the angular range of 0°–90°
Designed maximum surface heat flux	∼2.5 MW/m^2	The actual heat flux is lower than 1.4 MW/m^2
Width of flow channel	150–250 mm	Effective width
Outer diameter of the heating section	4800 mm	The same as the prototype RPV lower head
