In the September issue of Nuclear News, I asked if you’ve ever wondered why nuclear isn’t commonly considered the choice for clean power production. In that column and in August’s, I provided some information about the cleanliness and safety of nuclear for your use as you make the case for this clean energy source to friends and neighbors. This month, let’s talk reliability.

Today's ANS Nuclear Matinee shows viewers a time-lapse film of a steel superstructure being built on top of the dome of Sequoyah-2's reactor containment building. The work is being done to ready the site for a large maintenance project scheduled at the plant. When complete, the superstructure will support the removal of parts of the dome along with the reactor containment vessel and steam generator enclosures.

When I was registering for the various events scheduled to take place during the ANS Annual Meeting this past June, I was quite excited to see that one of the three technical tours would be at Exelon's Dresden Nuclear Station, not too far from downtown Chicago where the meeting was taking place. Luckily, I made the cut for attendance and was issued a ticket for the tour when I checked in at the meeting desk.

The economics of wind power

It is often stated that since no one can charge money for the wind, wind-generated electricity is free. This is not true. A modern wind turbine, which can generate 2 megawatts of electricity (MWe) when the wind is blowing, costs about $3.5 million installed. Five hundred of these turbines installed at a wind farm, to be able to generate 1000 MWe, would cost $1.75 billion. Add in other costs, such as for operation and maintenance (O&M) and transmission lines, and the total sum could match the approximate $4 billion required to build a nuclear plant.
