Exhibit 8-1

Pressurized Water Reactor

Pressurized water reactors (PWRs) involve three “loops.” The primary loop passes through the reactor core and carries away the heat energy generated in the fuel. The secondary loop absorbs the heat from the first loop in a component called a steam generator, and carries it to the turbine. A third loop rejects the unused heat energy to the atmosphere, either through a cooling tower or into a cooling pond or river.
