The team will hold technical meetings with TEPCO and the Ministry of Economics, Trade and Industry (METI).
The meetings will focus on issues related to the calibration and validation of the model, including data from various countermeasures that are currently in place.
Subsequently, the 3rd Mission of the International Peer Review of Mid-and-Long-Term Roadmap towards the Decommissioning of TEPCO's Fukushima Daiichi Nuclear Power Station Units 1-4 (3rd Decommissioning Mission) was conducted on 9 – 17 February 2015.
One of the advisory points given by the mission team was that TEPCO should consider producing a better calibrated, robust groundwater model, which would allow TEPCO to continuously evaluate and optimize the performance of various countermeasures taken at the Fukushima Daiichi NPS.
As a follow up, a team of IAEA and external experts will visit Japan from 15 – 19 February 2016.
A team of IAEA and external experts visited Japan from 15 – 19 February 2016 to hold technical meetings with TEPCO and the Ministry of Economy, Trade and Industry (METI) related to the modelling of groundwater flow at the Fukushima NPS.
The meetings focused on issues related to the calibration and validation of the model, including data from various countermeasures that are currently in place.
The IAEA team also participated in a technical seminar to facilitate a wider exchange of information on the nature of groundwater inflow at the NPS.
Japanese participants in this seminar included those from several academic, research and related institutions.
A summary report of the meeting that includes a list of participants is available HERE.
Following the March 2011 earthquake and tsunami, inflow of groundwater into the reactor buildings at the Fukushima Daiichi Nuclear Power Station (NPS) has resulted in the accumulation of significant quantities of contaminated water every day.
The storage and treatment of contaminated water are among the biggest challenges, requiring immediate and comprehensive countermeasures to reduce groundwater inflow, such as groundwater by-pass and sub-drain pumping systems, impermeable walls with a soil freezing method, seaside impermeable walls, etc.
A meeting of Japanese and international experts was held at the IAEA on 8 – 10 September 2014 to discuss groundwater contamination following the accident at the Fukushima NPS, which concluded that the IAEA could consider the following activities to further assist Japan in its efforts at the Fukushima NPS by cooperating in: i.
