Takafumi Anegawa led the OFNP project at COCN from 2020 to 2022.
Following the Fukushima Daiichi nuclear power plant accident, he played a pivotal role in leading nuclear reform activities at TEPCO as Chief Nuclear Officer. Additionally, he serves as the president of the CHAdeMO Association, one of the world's most widely adopted standards for EV fast charging.
Mr. ANEGAWA graduated from the University of Tokyo with a master’s degree in nuclear engineering and joined Tokyo Electric Power Company (TEPCO) in 1983. His first assignment involved core management at the Fukushima Daiichi Nuclear Power Station.
In July 1986, he was transferred to the Nuclear Power Construction Department at TEPCO’s headquarters. His responsibilities included core and fuel design, as well as transient analysis for nuclear power plant construction. Additionally, he participated in a study of KWU Pressurized Water Reactors (KPWRs) to evaluate the advantages of their design compared to Boiling Water Reactors (BWRs). Beyond these tasks, he contributed to investigation reports on the 1986 Chernobyl accident and the 1988 nuclear thermal-hydraulic instability event at the LaSalle Nuclear Power Station.
From 1991 to 1993, Mr. Anegawa was seconded to the Electric Power Research Institute (EPRI) program to develop the Simplified Boiling Water Reactor (SBWR). During this time, he worked at GE Nuclear Energy as a loaned engineer, focusing on thermal-hydraulic analysis of natural convection in the SBWR design. The SBWR served as a predecessor to the current BWR-X300 developed by GE.
Upon returning to TEPCO, he resumed his licensing work for nuclear core and fuel at TEPCO headquarters, a role he held until 2002. During this period, he contributed to licensing efforts to increase the burnup of the Advanced Boiling Water Reactor (ABWR) initial loaded core and to introduce Mixed Oxide (MOX) Fuel to Kashiwazaki-Kariwa Unit 3. One of his notable achievements was establishing burnup-based criteria for Reactivity Insertion Accidents (RIAs). Additionally, he served as a member of the EPRI Robust Fuel Program during this time.
From 2002 to 2011, Mr. Anegawa transitioned from nuclear engineering to a focus on electric vehicles (EVs). He collaborated with Subaru and Mitsubishi Motors to jointly develop a new generation of EVs capable of being recharged using high-power DC chargers—a groundbreaking technology at the time. His proposal for a charging protocol, later known as CHAdeMO, enabled the safe and efficient recharging of various battery systems without compromising their integrity. This concept has since influenced other charging standards worldwide.
During this period, Mr. Anegawa and his team were instrumental in creating the world’s first DC quick-charging technology, which played a pivotal role in the widespread adoption of electric vehicles. In March 2010, he founded the CHAdeMO Association, which quickly grew to include hundreds of members worldwide. Today, while several EV quick-charging standards exist, CHAdeMO remains the only standard with a proven success rate of over 99% for reliable charging, supporting multiple OEM EVs. Mr. Anegawa continues to serve as the president of the CHAdeMO Association.
After TEPCO’s Fukushima Daiichi nuclear accident in 2011, Mr. Anegawa dedicated seven years to recovery efforts. He served as General Manager of the Asset Management Department from 2011 to 2013, Deputy Chief Nuclear Officer and Managing Executive Officer from 2013 to 2014, and Chief Nuclear Officer from 2014 to 2017. During this time, he led the Internal Task Force to investigate the root causes of the accident and authored a comprehensive report on lessons learned. He applied these lessons to enhance safety measures, particularly for the restart of the Kashiwazaki-Kariwa nuclear power plants. One of the key outcomes of these efforts was the inhouse development of a filtered venting system to improve plant safety.

He integrated these lessons into enhanced safety measures, particularly for the restart of the Kashiwazaki-Kariwa nuclear power plants. One of the significant achievements during this period was the in-house development of a filtered venting system to improve plant safety.
After stepping down as Chief Nuclear Officer, Mr. Anegawa served as President of the TEPCO Research Institute until March 2021. In this capacity, he oversaw a diverse portfolio of research and development activities, including renewable energy innovations, nuclear restoration projects, and advancements in the electrification of transportation.
In 2019, he contributed to the establishment of e-Mobility Power Co., Inc., which has become Japan's largest charging point operator, managing a network of over 27,000 chargers nationwide. Under Mr. Anegawa's leadership as Chairperson, e-Mobility Power has been instrumental in advancing electric vehicle adoption in Japan by delivering reliable and accessible charging services.
From 2020 to 2022, Mr. Anegawa served as the project leader for the Offshore Nuclear Power Investigation Project under the Council on Competitiveness Nippon (COCN), driving innovative solutions in offshore nuclear energy development.
