TEPCO has been working on a complex and lengthy decommissioning process at the site, with a focus on revitalizing the environment and industries of Fukushima.
The Fukushima Daiichi plant was TEPCO's first nuclear power facility, with its No. 1 reactor beginning operations in 1971. The plant was designed and constructed in conjunction with General Electric, and TEPCO elected to follow GE's design closely during construction. TEPCO's analysis determined that the site elevation was safe from tsunamis due to the protection provided by the sea wall. However, the lower elevation did increase the vulnerability to larger-than-anticipated tsunamis.
In the aftermath of the Fukushima disaster, TEPCO faced significant financial losses and scrutiny over its handling of the situation. The company received support from the Japanese government to prevent its collapse and ensure a continued electricity supply to the affected areas. TEPCO has also faced criticism for a lack of transparency and deception regarding nuclear safety, with revelations of past concealment and falsified information coming to light.

TEPCO's Fukushima plant design and safety record have been scrutinised
The Fukushima Daiichi Nuclear Power Plant is a disabled nuclear power plant located on a 350-hectare site in the towns of Ōkuma and Futaba in Fukushima Prefecture, Japan. The plant was operated by the Tokyo Electric Power Company, also known as TEPCO.
In the aftermath of the accident, it was revealed that TEPCO had failed to address warnings about the plant's vulnerabilities. For example, in 2008, the IAEA warned that the Fukushima plant was built using outdated safety guidelines and might not withstand a large earthquake. Filmmaker Adam Curtis also highlighted the risks associated with the boiling water reactor cooling systems, claiming that these risks had been known since 1971. Additionally, TEPCO was warned that the seawall was insufficient to protect against a powerful tsunami but failed to take adequate measures.
The consequences of the accident were significant, leading to the displacement of 50,000 households in the evacuation zone due to radioactive leaks. TEPCO faced scrutiny for its handling of the situation, including its communication of information to the public. The company also submitted a report in February 2011, admitting that it had previously provided fake inspection and repair reports, further damaging its reputation.
In the years following the accident, TEPCO focused on decommissioning the damaged units and addressing environmental concerns through monitoring radioactive substances in seawater and marine products. The company also received financial support from the Japanese government to prevent its collapse and ensure a continuous electricity supply to Tokyo and nearby areas.
