Case definitions.

Case	Definition
17	Constant spacer loss coefficients (not Reynolds number dependent).
	Trip valve isolates PCU at 𝑡=9010s.
26	Similar to Case  17 but has the spacer loss coefficient becoming Reynolds number dependent after 𝑡=13000s.
32	Similar to Case  17 but with Reynolds number dependent spacer loss implemented at 𝑡=1000s.
	Constant guard containment pressure of 800 kPa is initiated at 𝑡=1250s.
