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


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


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).
