3. COLLECTION AND PREPARATION OF ALPS TREATED WATER SAMPLES
Samples for this ILC were collected on 24 March 2022 from the K4-B ALPS facility at FDNPS, with observation by IAEA staff members.
The K4-B tank group is one of three measurement and confirmation units in the ALPS discharge facility that was under construction at FDNPS at that time. It is comprised of 10 individual 1,000 m° storage tanks that have been re-utilized for this purpose. The tanks are interconnected and the contents are circulated by pumping. Additionally, the water in individual tanks is agitated Previously, TEPCO had performed a circulation and agitation experiment at K4-B to demonstrate the adequacy of its method for ensuring the homogenisation of the ALPS treated water content prior to sampling [7]. Once the discharge facility has been completed, this will become normal practice under TEPCO's source monitoring plan.
Prior to sampling for this ILC, circulation and agitation was conducted in the same way by
TEPCO for 14 days to ensure inter sample homogeneity and, thus, suitability of the samples for the provision of comparable results of analyses.
The samples were collected directly from one of the interconnection pipes at K4-B. A volume of 25.3 L of ALPS treated water was collected for each participating laboratory: 5 x 5 L in plastic cubitainers and 3 x 100 mL in amber glass bottles. The sample containers were assigned and labelled beforehand and were immediately sealed with tamper proof tape under IAEA observation. The samples were not acidified or filtered prior to shipping.
The samples were received by the IAEA laboratories in Monaco and Austria and by the participating ALMERA laboratories between August and October 2022.
