Tour of the Tomari Nuclear Power Station of Hokkaido Electric Power Co.
1．Outline Overview
Participants will visit Tomari Nuclear Power Station of Hokkaido Electric Power Co.
First, visitors will learn about the outline of a nuclear power plant conceptually at Tomarin-kan.
Next, outside, the tour will visit seawalls and other facilities related to disaster prevention systems
against natural disasters.
In the indoor facility, we will enter the control area where control equipment, power generationequipment, reactor equipment, and fuel handling equipment are located. In particular, thanks to thecooperation of Hokkaido Electric Power Company, we will be able to enter the actual reactor
containment vessel. This is a rare and extremely valuable opportunity.
Finally, you will actually touch the simulator equipment and experience the operation of the reactor.
During the tour of the power plant, you will be escorted by Hokkaido Electric Power Company
employees, including Hokkaido University alumni, who are your seniors, so this is a valuable
opportunity to hear the real voices of those who work at nuclear power plants.
