Progress status of “PCV lower-section repair technology” test

May.30,2014

The investigation and repair of primary containment vessel (PCV) leak locations are indispensable for water filling according to the fuel debris retrieval plan in the “Mid- and-Long-Term Roadmap” and for preventing contaminated water levels from increasing.
The progress status of the R&D project for the “inspection/repair of leaking locations using PCV lower-section repair technology” in the subsidy project of the Japanese Ministry of Economy, Trade and Industry (METI) is as follows:

Evaluation of the Distribution of On-Site Radioactive Nuclides by Radiochemical Analysis of Standing Trees

May.09,2014

The Japan Atomic Energy Agency (JAEA), a member of IRID, conducted a project of radiochemical analysis of standing trees at TEPCO’s Fukushima Daiichi Nuclear Power Station (NPS).  This analysis was part of a study to collect and evaluate basic data needed to examine methods to process and dispose of radioactive waste generated at the site. The JAEA led this R&D project with partially funding from the Japanese Ministry of Economy, Trade and Industry (METI).
