Following up this article..[Elephant foot ?] Tepco collected highly radioactive sediment in reactor2 PCV, “0.2 Sv/h of γ and β” [URL]
In the second TIP (Traversing In-core Probe) guide pipe soundness test, Tepco collected the same highly radioactive sediment again.
TIP is the sensoring system to monitor gamma and neutron.
They inserted the dummy TIP cable for 8.6 m into reactor2 PCV. The sediment was attached on the top of the cable.
It was 2~3mm, looks gray gold. γ dose was 14 mSv/h, γ & β dose was 30 mSv/h.
It is not verified what this substance is made of.
