Landside tritium leakage over through years from Fukushima Dai-ichi nuclear plant and relationship between countermeasures and contaminated water

K. Shozugawa, M. Hori, et al.

This groundbreaking study dives into tritium groundwater leakage from the Fukushima Dai-ichi Nuclear Power Plant, identifying potential sources and emphasizing the urgent need for enhanced monitoring systems. Conducted by a team of experts including Katsumi Shozugawa, Mayumi Hori, Thomas E. Johnson, and others, the research spans from 2013 to 2019, uncovering average tritium concentrations and highlighting critical environmental concerns.

Abstract
This study investigates tritium groundwater leakage from the Fukushima Dai-ichi Nuclear Power Plant (FDNPP) to the land side, observed continuously from 2013 to 2019. The average tritium concentration was approximately 20 Bq/L. Two possible sources are postulated: leaks from a contaminated water tank (2013-2014) or leakage of tritium that had spread widely under the site. The study emphasizes the need for strengthened tritium leakage monitoring systems on both the sea and land sides of the plant.
