Nuclear Power Plant Siren Systems

[bigloudnoise]

In Iowa, the Duane Arnold Energy Center siren system uses all Whelen sirens. A majority of them are WPS-4004s and WPS-3016s. There are also a few 2016s included in the mix in some areas. As for how many sirens there are, their locations, coverage, etc, I unfortunately do not have that information, nor was I able to locate it during my research.

Susquehanna - they publicly announced that they were not going to operate the ATI horns and are suing ATI for non-performance. I don't think they have publicly announced who the replacement vendor is. The present system has 114 sirens, the new one will have ~80 sirens.
Calvert Cliffs - predominantly T-128's with a few T-121's - 73 sirens in all.
Diablo Canyon - replaced their sirens on a one-for-one basis with Federal 2001SRN-B, Eclipse, and Eclipse8 sirens - all can operate on battery back-up. They test once per year in August - ~130 sirens in all.
San Onofre expands its siren based on new housing developments going in. They use all Whelen's.
D C Cook - all Whelen's in their new system - WPS-2750, WPS-2800 and WPS-2900's - predominantly 5's with a few 6's - ~40.
Artificial Island (Hope Creek/Salem) - their new system uses all T-121's - ~50.
Limerick and Peach Bottom - use predominantly T-Bolts, with a few 2001's for some recent replacments. Limerick has ~165 sirens and PBAPS has ~100.
TMI - 104 sirens in a mixed bag of 2001's, Cyclones, P-10's and maybe a T-128 or two.
Exelon Illinois - Byron/Braidwood/Quad Cities/Clinton/LaSalle - they are in the process of changing over to all ASC's. The new systems will be T-128's and T-132's - all of which will operate on battery back-up. The P-50/T-135 is AC power only. The T-132 looks like a T-128 on steriods.
Monticello and Prairie Island both have ~100 sirens each. All but one are 2001's. The Modulator is in front of the casino near the front gate to Prairie Island. It "stutters" at site area emergency to warn people inside the casino. Normally, the sirens are to go off when a general emergency is declared - SAE is one step down from that.
Palisades - all 2001's
Davis-Besse - all 2001's
Fermi 2 - all 2001's
Beaver Valley - a mixed bag. The new sirens are all 2001's. They also have P-10's, Cyclones and a pair of Klaxon horns at the nudist colony along the PA-OH border.
Comanche Peak - the older sirens are T-beams. The newer sirens and add-ones are 2001's.
Grand Gulf - uses all ASC - I think they are all T-121's.
River Bend and Waterford use predominantly Whelen 2800's with a few 2000's and 3000's thrown in.
Pilgrim uses all Federal - the new ones are all Modulators with some EOWS-115's (all upgraded electronics) thrown in.
Seabrook uses Whelens - Model 3000 and Model 4000's.

VA_Nuke_Pete has proven that his information is more than correct... I was just up in Berwick yesterday (home of the Susquehanna plant he is talking about) and low and behold there are ASC T-121's all over the place and no more rotating ATI sirens. There is one 1 T-112 in the system which is in downtown Berwick... this siren is used as a combination fire siren/nuclear power plant warning siren.

Dang I remember when that Cyclone sounded at 2 am for like 40 min that was crazy

The Indian Point (Westchester County, New York) siren system will be tested at 11:00am June 4, 2008, for about four minutes. It's a system of P10s - P15s being phased out in favor of ATI. I don't believe the ATIs are active yet or that any ACAs have been taken down.

The ATI's are active, and theres actually a test vid. on youtube...i do not know if the other sirens have been taken down yet however.

[Tannre]

In Oregon, the Trojan plant has 2001-SRNB or 2001-130's I cant remember, and I think Allertors.

[Spraynard]

The Kewaunee and Point Beach systems in Wisconsin are made up of ACA P-15's and Allertors.

Looking back...I know they had Thunderbolts before, and I think there were a few STH10 and model 5's mixed in, too.

I wonder what they did with all of those T-bolts...(I don't want them, one is enough for me).

Did I ever mention how much of a female dog it was to move the Thunderbolt between the four different residences I've had since I acquired it?

Doesn't Chicago have a Nuke Plant?

[va_nuke_pe]

Not since the atomic pile during WWII. However, the closest operating commercial nuclear plant to Chicago is the Dresden station. Zion (in Zion Illinois right on the IL-WI border) was shut down permanently about 10 years back.
