A Two-Step Approach to Uncertainty Quantification of Core Simulators

Table 2

Uncertainty in the effective multiplication factor from using the two-step and XSUSA methods with a sample size of 290.

	Two-step method	XSUSA method	Absolute difference (pcm)
𝑘-eff mean	1.30268	1.30330	62
𝑘-eff stand. deviation	0.00569	0.00564*	5
Relative SD %	0.43706	0.43272

*The 95% confidence interval is [0.00522, 0.00614].
