Hsieh was named minister of the
Atomic Energy Council in April 2016, and took office on 20 May, with other members of the
Executive Yuan formed by
Lin Chuan. Shortly after assuming their ministerial posts, Hsieh and economic affairs minister
Lee Chih-kung were sued by anti-nuclear activists, after Lee had proposed reactivating the first reactor at the
Jinshan Nuclear Power Plant. The reactor had been shut down since December 2014, during the ministerial tenure of
Tsai Chuen-horng. At the time the plant was decommissioned,
Taipower was unable to remove as many spent fuel rods as planned, due to storage limits. Activists filed a separate lawsuit against premier Lin Chuan. In response to allegations that the AEC's previous actions had favored Taipower, Hsieh vowed to increase the council's transparency and invite public participation. In June 2017, Hsieh was questioned about plans to convert the loading pools at
Guosheng Nuclear Power Plant to fuel storage sites. Hsieh retained his role when
William Lai became premier. In November 2017, Hsieh reported to the
Legislative Yuan about the AEC's plans to decommission three nuclear power plants, and subsequently convert them to geothermal power plants. In March 2018, Hsieh announced the imminent restart of the second reactor at Guosheng, which had been closed since May 2016, due to a glitch in its electrical grid. He repeatedly reiterated the government's intent to phase out nuclear power by 2025, as well, In 2019, Hsieh described proposals to activate the
Lungmen Nuclear Power Plant as impractical for budgetary and seismological reasons, and continued reporting on efforts to send fuel rods meant for the plant back to the United States. In 2021, the Japanese government stated that it would begin releasing treated wastewater from the
Fukushima Daiichi Nuclear Power Plant into the ocean. Taiwan's representative to Taiwan,
Frank Hsieh, faced calls to report to the legislature and be recalled from or resign his post. Following the Japanese announcement, the AEC sent a number of Taiwanese researchers to investigate wastewater discharged from Daiichi. Hsieh Shou-shing planned to send a Taiwanese delegation and government funds to participate in a
United Nations mission to review Daiichi wastewater discharge. The AEC also considered starting a fund to compensate Taiwanese fishers affected by contaminated wastewater. In October 2022,
Mirror Media reported on allegations of physical and verbal harassment against Hsieh, who was duly placed under investigation by the Executive Yuan, and granted leave in December. Following the end of the investigation, Hsieh was removed from office on 11 January 2023. In July 2023, the
Control Yuan voted unanimously to impeach Hsieh. The Disciplinary Court fined Hsieh NT$600,000 for disregarding
COVID-19 pandemic regulations, and instances of sexual harassment, sex-based discrimination, and workplace bullying. ==References==
