Japanese Economy, Trade and Industry Minister Nishimura Yasutoshi has inspected a next generation nuclear reactor being developed to produce energy more efficiently.

Nishimura visited a research center of the Japan Atomic Energy Agency in Ibaraki Prefecture, near Tokyo, on Saturday.

He observed the prototype of a high temperature gas-cooled reactor, or HTGR. It uses helium gas for coolant, and is touted to have superior characteristics of safety and economy.

Nishimura's visit comes as the government considers promoting the development and construction of next generation reactors. It plans to utilize nuclear power to achieve stable power supply and carbon neutrality.

During the closed inspection, Nishimura is said to have received an explanation about the reactor's characteristics while he was inside the test reactor's containment vessel.

The minister later told reporters he believes nuclear power is extremely important to achieve both stable power supply and decarbonization.

He said he had heard that some supply chains are in danger because of the suspension of operations at some nuclear plants.

Nishimura said the government will provide the necessary support to promote its energy policy, including human resources and technology.
