Human resource development

JAPC has planned and constructed the first units of various reactor types and experienced O&M and decommissioning of NPP for more than 40 years.JAPC has accumulated the expertise from the viewpoint of a Nuclear power utility by implementing all the process of the business on its ownBased on those experiences, JAPC expands the overseas business to provide appropriate consulting and support from the viewpoint of a Nuclear power utility to the countries to introduce nuclear power generation.

12

Using our own training facilities, JAPC can offer a comprehensive range of education and training depending on each country’s need. So far, we have provided education for approximately 29 countries, 614 people.

Responding to requests, we can corporate to develop the basic design of training centers or the education curriculum.

Training using an educational simulator of nuclear power generation

Practical training to learn how to prepare a master plan

Radiation measurement trainingPractical work to learn how to dismantle and inspect pumps

Special Project

People are the “KEY”• “People” did it all: contemplating, planning

and putting into practice measures to find a way out of this situation– Removing debris, cooling reactors with

fire engines, restoring power supplies, cooling with temporary pumps, reinforcing spent fuel pools and adding water, fueling power-generating vehicles and fire engines and many other tasks were all the work of people

– Most of the responders lived in the local community and they performed their work while worrying about whether their families were safe and had evacuated

– Many of the employees prepared themselves for the end

Examples of Flexible Responding

③ Pure water supply for water injection into the reactor (U.S. barge)

19

① Water injection into the reactor core by fire engines and temporary pump（use of water for fire-fighting, intruded water and seawater）

② Recovery of cooling seawater system by installing temporary pump, control panel, power supply from outside of the plant (at Unit 5, 6)

Messages from Fukushima-50“There is no way we can protect the lives of the local residents if we can’t protect the lives of the people on site.” Former Site Superintendent Yoshida

Were we aware of what an important role people

play?

“If the operators had left the control room it would’ve meant that we had given up trying to control the reactor. In other words, we would have been abandoning the community and our families who had put their trust in us.” Former Unit 1, 2 Shift Supervisor Izawa
