Collaborative governance mechanism for nuclear contamination data in the Pacific Rim region in the context of transboundary nuclear damage accountability inflicted by Japan

As a radioactive waste disposal activity for the Fukushima nuclear accident, Japan government discharge multiple rounds of nuclear-contaminated water will ultimately cause irreversible transboundary damage to the public health, fishery economy, and marine ecosystems of Pacific Rim coastal countries. With the gradual implementation of Japan's commitment on the issue of the discharge of Fukushima nuclear-contaminated water into the sea, experts from many countries, including China, have headed to the Fukushima Daiichi nuclear power plant to collect samples. Currently, Facing the absence of an international monitoring mechanism for nuclear-contaminated water has led to low transparency regarding radioactive data from nuclear waste and environmental monitoring data of surrounding marine areas. This article analyses the legal problems faced by the Pacific Rim region in the recovery of transboundary nuclear damage by utilizing literature research method, arguing the feasibility of the construction of a regional synergistic governance mechanism for nuclear contamination data, then advocating a framework for the construction of a regional collaborative governance mechanism for nuclear contamination data, however, the establishment of such mechanism in the Pacific Rim region involves multiple complexities. Regional Nuclear Energy Powers as Lead Countries, seeking to promote the governance mechanism from theory to practice. Therefore, the systematic promotion of the construction of a collaborative governance mechanism for in the Pacific Rim region can remedy the lack of an international monitoring mechanism for nuclear-contaminated water and providing institutional legality for the recovery and compensation of transboundary nuclear damages in the Pacific Rim countries.
