Analysis of Loss of Flow Events on Brazilian Multipurpose Reactor Using the Relap5 Code

Table 4

Reference and calculated results for 30 MW power condition.

Parameters	Reference	RELAP5	Error (%)*	Acceptable error (%)
Inlet and outlet core coolant temperatures (K)	311.0/320.0	311.0/320.0	0.0/0.0	0.5
Inlet and outlet pool coolant temperatures (K)	306.0/—	307.0/312.3	0.4	0.5
Mass flow rate from pool to core by chimney (kg/s)	83.3	83.1	0.2	2.0
Inlet and outlet core mass flow rate (kg/s)	750.0/833.0	748.0/831.0	0.2/0.2	2.0

∗Error = 100 × (calculation − reference)/reference.
