Daya Bay requires about 900 staff members for its operation. About 700 staff members work in the technical departments and more than two third of them have received university education.

All staff who work in the nuclear power station have to undertake stringent training on nuclear safety.

All of the senior operators and operators have to obtain a licence issued by the National Nuclear Safety Administration before they can start working in the control room. They have to sit for a re-qualifying examination every two years. They also have to attend simulator training to keep themselves abreast of latest technologies.

International and local contractors who are engaged to work on plant projects and at the refuelling overhauls are also subject to stringent training in line with international practice.

GNPS still maintains a small team of international advisors, most of whom are French engineers seconded from Electricite de France.

With a view to learning from the world's best practices, Daya Bay organises regular exchanges and seminars with international bodies such as the World Association of Nuclear Operators and International Atomic Energy Agency, and with its sister plants in South Africa, Belgium, and in China.
