Analysis of ALPS treated water as third-party



Q:Do you use the same analysis methods as Tokyo Electric Power Company HD(TEPCO)?

A:The analysis methods are basically the same as those used for TEPCO HD, but some nuclides are analyzed differently. JAEA, as a third-party, selects our own analytical methods for ALPS treated water, focusing on the analysis methods determined by the government (official methods). It is considered that conducting the analysis in a different way from TEPCO HD has the benefit of confirming the results from multiple perspectives.

Q:What is “uncertainty” appeared in the analysis results.

A:Analysis results contain variation within certain range due to various factors. The “uncertainty” is the degree of variation in analytical value.
Since the uncertainty depends on the analysis conditions, it varies among the analytical workers.
