In this paper we study the analytical and statistical results of estimating the gamma dose rate at pool access floor in TRR when the core shield accidentally decreases to some non-permitted levels.Due to the risk of experimental techniques,we use the analytical and statistical methods.In normal conditions(no risk),the discrepancies between experiment and two methods are justified and it is found that for such problems we have to normalize these methods to experimental results as follows:the analytical method by factor 0.13 and MCNP by 1.7.
