Japan’s Nuclear Revival Stalls Amid Scandals and Delays

Setbacks to Reactor Restarts Threaten Power-Supply Goals
Japan’s plan to expand nuclear generation is being undermined by a series of scandals and regulatory hurdles that have delayed the restart of several reactors. BloombergNEF (BNEF) now projects that only nine reactors—totaling about 9.6 gigawatts (GW)—will be back online by 2040, a reduction from an earlier outlook of eleven units. The revised forecast leaves the country at least 11.7 GW short of its 2040 target of 35 GW of nuclear electricity.
Background: Post-Fukushima Revival Efforts
Since the 2011 Fukushima disaster, Japan has pursued the resumption of reactors that were shut down, aiming to curb reliance on costly imported fossil fuels. The strategy has faced persistent opposition and a strict regulatory regime, leaving just 15 of the nation’s 33 operable reactors currently active.
Data and Statistics
- Planned restarts: 9 reactors, 9.6 GW (BNEF).
- Target shortfall: >=11.7 GW below the 35 GW 2040 nuclear goal (BNEF).
- Recent withdrawals: Chubu Electric Power Co. pulled applications to restart two units at the Hamaoka plant after accusations of fabricated seismic data.
- Construction accident: A fatal incident during seawall construction at Hokkaido Electric Power Co.’s Tomari plant led regulators to reject proposed safety measures, pushing the restart of Tomari Unit 3 to 2028 (BNEF).
- Electricity market impact: Spot prices have risen to their highest level since 2022, pressured by reduced LNG supplies following disruptions in the Strait of Hormuz.
Official Statements & Responses
Regulators have rejected Hokkaido Electric’s safety proposals, citing the need for stricter seismic safeguards. Industry analysts warn that without additional nuclear capacity, Japan will have to rely more heavily on coal or liquefied natural gas (LNG) imports to meet baseload demand, especially as data-center electricity consumption is expected to surge.
Verbatim Quotes
- “We expect Japan data center power demand to double by 2030 from current levels,” — Robert Liew, director of integrated energy research at Wood Mackenzie Ltd
These developments cast doubt on Japan’s ability to meet its nuclear-generation targets and could keep power prices elevated while the country remains exposed to volatile global energy markets.
