Keywords:autocorrelation method, prompt neutron decay constant, statistical uncertainty, unbiased estimation, stationary bootstrap method

In order to appropriately quantify the statistical uncertainty of the autocorrelation method from a single measurement of the reactor noise, this study aims to investigate the applicability of the the stationary bootstrap method with the unbiased estimation for the autocorrelation.
