Q. Energy security and public trust are often in tension in democratic nuclear policy-making. Illustrate with reference to Japan's post-Fukushima experience. (15 marks, 250-350 words)

Japan imports close to 90% of its energy, yet the Fukushima Daiichi accident of March 2011 — rated INES Level 7, a severity shared only with Chernobyl [1] — cost nuclear power its social licence overnight. Its fifteen-year journey back illustrates how a democracy must earn consent for what its energy balance already demands.

The energy-security imperative - Shutting all 54 reactors forced substitution by imported LNG, coal and oil, exposing the economy to price and geopolitical shocks, sharpened after 2022. - Restarts directly ease this: Kashiwazaki-Kariwa Unit 6 (1,356 MW), restarted on 9 February 2026, can alone displace about 1.3 million tonnes of LNG imports a year [2]. - Decarbonisation reinforces it — the 7th Strategic Energy Plan (February 2025) targets roughly 20% nuclear by 2040, against 8.5% in FY2023, beside 40–50% renewables [3].

Public trust as a democratic brake - Regulatory reconstruction came first: the independent Nuclear Regulation Authority (2012) replaced a regulator seen as captured by the industry, imposing stricter seismic and tsunami standards. - Local consent remains a de facto veto: the Niigata prefecture's approval in December 2025 was the precondition for the Kashiwazaki-Kariwa restart [2]. - The operator's credibility deficit — TEPCO's post-accident disclosure failures — kept scrutiny high even after technical clearance.

Where the tension bites - Result: only 14 reactors restarted in over a decade [4], far short of the fleet the 2040 target assumes — trust, not technology, is the binding constraint. - Unresolved radioactive waste disposal, unreturned evacuees, and the internationally reviewed ALPS-treated water discharge [1] keep legitimacy contested.

Japan's experience shows the two goals are sequential rather than opposed: energy security is delivered through trust, not despite it. Transparent regulation, honest disclosure and genuine local participation convert a technical case into a political mandate. For India's own expanding civil nuclear programme, the lesson is that credible, independent safety governance is the cheapest form of energy security.
