For the corroboration of source monitoring, samples of ALPS treated water that is considered by TEPCO to be ready for dilution and discharge – pending final confirmation by analyses – are being collected from tanks at FDNPS.

Sample collection and pre-treatment activities undertaken by TEPCO, and relevant Japanese authorities will be facilitated and observed by the IAEA

During the first review mission to TEPCO/METI held in February 2022, IAEA staff were on-site at FDNPS to witness the collection of initial ‘test samples’ of ALPS treated water.r. Test samples are used

to conduct preliminary analyses for verification of methods and to assess any changes or refinements which may be required regarding the instructions for laboratories participating in the ILCs being used

to undertake the corroboration of source monitoring. Results of analyses of these initial samples will not be intercompared but are being used by the IAEA to determine the physical and chemical properties of the ALPS treated water. The samples for each IAEA laboratory are comprised of 25.3 L of ALPS treated water sampled from the K4-B tanks at FDNPS (prior to dilution with seawater).

In October 2022, the IAEA witnessed the collection of two additional batches of samples of ALPS treated water. These samples are being used in the second and third ILCs to support the corroboration of source monitoring. The samples were collected from the G4S-B10 and the G4S-C8 tanks.
