Japan is taking steps to restart the Kashiwazaki-Kariwa Nuclear Power Plant, the world's largest nuclear power plant, nearly 15 years after the Fukushima incident. The Niigata Prefectural Assembly has passed the local consent procedure, and Tokyo Electric Power Company (TEPCO) can proceed with plans to restart Units 6 and 7 after completing a safety inspection and obtaining other relevant approvals. This announcement will be a significant step in Japanese energy policy to reduce dependence on imported fossil fuels, boost energy security, and increase the share of nuclear in the electrical grid. Operations are anticipated to commence as early as 2026.
Why Kashiwazaki-Kariwa Nuclear Power Plant Shutdown?
-
The 2011 nuclear disaster in Fukushima, Japan, halted nuclear operations around the country to review its safety, which led to the closure of the plant.
-
Tighter post-Fukushima safety measures necessitated massive improvements and inspections that stalled restart arrangements.
-
Security breaches, such as flaws in anti-terror and access control systems, led the regulating bodies to shut down operations.
-
The approval of the restart was based on local government and popular approval, which extended the shutdown.
-
Long-term lack of action was caused by strong public opposition and safety concerns regarding nuclear power.
