The Siren Board

What will become of the old sirens? Who exactly owns them?

The sirens are owned by Exelon Nuclear. They will be removed and held for spare parts to keep other plants running until all plants can be upgraded. Some of the sirens will be donated to communities that need them. Many may end up being scrapped if they are in too poor of condition.

All that steam comes from the water entering the cooling tower.

I'm just stating it looks hotter than normal.

Braidwood power plant and zion both are without towers. Zion used lake michigan water for its condenser water. Braidwood uses water from Lake Braidwood. None of the water in the lakes or cooling towers in general comes in any nuclear contact, its just condenser water. Same as the building I used to work in downtown, we used water from the Chicago River to feed the condenser water side of our Carrier centrifugal chillers. It was cheaper than towers and it always worked, even in rain and very high humidity, whereas towers have a hard time releasing moisture into very moist air. It was also much simpler and efficient.

I just realized that no steam is comming out of the second cooling tower


Has anyone ever seen a Nuclear power plant that DOESNT have cooling
towers? My uncle works at Dresden Nuclear (and also lives 2 blocks away)
and there are NO cooling towers

I believe they have other kinds of cooling apparatus; long low rectangular structures.
Was told the towers arextremely expensive to build, but also morefficient.

They only need both in operation according to power demands.
