Our visit to this nuclear power plant opened our eyes to the benefits of nuclear power and cleared up some misconceptions about its dangers.

Location is very important for a nuclear plant. Seabrook Station is near the ocean because of the need for large amounts of sea water for cooling. The containment dome is built on solid granite bedrock, extending 60 feet below sea level, and is the only double-walled, steel-reinforced concrete containment in the world. It is built to withstand any natural disaster, including severe earthquakes, and could even survive a direct crash from a FB-111 bomber jet.

We learned how efficient nuclear fuel is compared to the alternatives, and that the amount of waste involved is only a fraction of the others.

Seabrook is committed to public safety and to preserving the environment. The beautiful marsh lands surrounding the plant are evidence of this objective.

Harrison explains nuclear fission: "A neutron hits a nucleus and makes it unstable. It explodes, giving off heat and energy, fission fragments and more neutrons. The neutrons hit the fragments, making them unstable, causing them to explode, and so on."

The energy from the nuclear reaction heats water in the reactor which flows in pipes through a separate water system. This water turns to steam which rotates turbines that spin electric generators. Ocean water from two 3-mile long underwater tunnels cools and condenses the steam back into water, which cycles through to be made into steam again. The electricity produced by the Seabrook Station provides electricity for 1 million homes.

This is a 1/4 scale model of a fuel cell. Dad is holding up the control rods, which are used to control a nuclear reaction. When the rods are lifted, more neutrons are released and heat energy rises. The opposite happens when the the rods are lowered.

Amanda said, "Dad taught us how a fuel cell works. Inside each of the tubes are tiny ceramic pellets of uranium stacked up on top of each other."

Harrison learned how efficient uranium is. "The pellets are about an inch long and 1/4 inch wide. One pellet produces the same amount of energy as one ton of coal or 17,000 cubic feet of natural gas or 3 barrels of oil! Each fuel rod holds over 100 pellets and there are 196 rods in a cell. There are dozens of cells in a reactor."

We viewed the simulated control room where people are trained to run the power plant. It takes years to become certified to work in a nuclear plant. The simulator is an exact replica of the real control room. Employees are required to spend one week in six in the simulator and in a classroom to maintain their licenses and to make sure they are prepared for every possible situation.

Enrico Fermi, Nuclear Physicist

Enrico Fermi was the first to produce a controlled, sustained nuclear fission chain reaction. He worked on the "Trinity" project during WW2 which produced the first nuclear weapon. After the bombing of Hiroshima and Nagasaki, Japan, Fermi lobbied against developing further nuclear weapons.

Trip Tips

Don't make the same mistake we did and try to enter the actual power station. Tours are at the Science and Nature Center--follow the signs.
