Uncertainty in calculated surface temperature and surface heat flux of THTF heater rods
Technical Report
·
OSTI ID:5853307
The report presents a procedure for determining the uncertainty in the output of a complex computer code resulting from uncertainties in its input variables. This method is applied to ORINC (Oak Ridge Inverse Code) to estimate the uncertainty in the calculated surface temperature and surface heat flux of a THTF heater during a blowdown transient. The significant input variables are identified and 95% confidence bands are calculated for the code outputs based on the uncertainty in these input variables.
