Three Mile Island Siren System Activation

This recording was taken at my house when they did the annual test. The sirens heard are cyclones and p-10's.

On March 28, 1979, and for several days thereafter, as a result of technical malfunctions and human error, Three Mile Island’s Unit 2 Nuclear Generating Station was the scene of the nations worst commercial nuclear accident. Radiation was released, and a part of the nuclear core was damaged, and thousands of residents evacuated the area. Events here would cause basic changes throughout the world’s nuclear power industry. Hey, today is March 28th!

[@blackmaxima]

I happened to be outside in newberry township during one of the last tests this past year after the complete switchout to the new gray sirens. It was eh. Just recently all the old sirens have been taken down, for a while, the new and old sirens were side by side. I think they even took down the cyclone here in new cumberland, which used to sound for fire calls too.

[@theowlfan9050]

same as 1:53 i guess at 1:53 they took it's cone off.

[@joeyindie4124]

The Owl Fan why they took it off? did the cone used to protect the input from rain, and stuff?

[@theowlfan9050]

IDK

[@CentralPASirens]

it was mounted at eye level for viewing at the TMI public center. The hat was removed around 2000 and the siren around 2012.

[@TheMatsushitaMan]

ITS* cone, not IT'S cone. Learn the difference between ITS and IT'S.

[@Thunderbolt_1000_Siren]

nice but the penetrators are not P-10s their P-15 because P-10s are single toned and sound like a sentry defender and the P-15s are dual toned and are mostly 9/12 port. just saying.

[@BritishRailwaysandSirens]

Thunderbolt 1000 Siren Productions no P-10s can only be dual toned. P-15s can be dual 9/12 or single tone 8 port

It invokes fear in a lot of people. Thats the point of a siren. To tell you somethings wrong and you need to take cover.

[@ObamaTookMyCat]

i hope these companies (FS, ASC) go back to the golden days of siren producing.... the T128 is ASCs only hope, whilst its a miracle that the STH10, and model 2 are still being made by FS...

Actually, the STH-10 was discontinued in 2006, but they still make Model 2s

All of the old ACA Cyclone 125's in the Oyster Creek NGS system in Ocean County, N.J. are being replaced by ASC Tempest T128's because unfortunately the Cyclones are older units and some didn't operate correctly for warnings prior to Hurricane Sandy. But the T128 is a good unit also .

[@patrickrogers9499]

Some of them were installed in the early 1970's .

[@alexbailey7291]

My cousion lives in Ocean County. There is 1 cyclone by his house.

I don't know how long ago you saw that Cyclone , but I'm 99.99 % sure that Excelon has replaced them all by now .

it sucks that the P-15 and Cyclones are being replaced by T-128s.:( I would want to hear those sirens so badly! I live in Montgomery county and our limerick thunderbolt 1000s and 1000Ts are all ready dead because their wires are cut. D: the Thunderbolts in Peach bottom are also being replaced by T-128s but the thunderbolts still are active cause the T-128s have no antennae. T-128 are not even loud so no offense but T-128s suck a little and their boring too. T-bolts, P-15s and Cyclones are louder

[@northwesternohiorailfan5622]

Thunderbolt 1000 Siren Productions AGREE I LIKE OLD SIRENS BETTER :D

[@ObamaTookMyCat]

i live up in harford county, and i used to be a siren enthusiast back before 2011 and i occasionally "check in", and i have to say, i never knew that peach bottom had a thunderbolt system until i found one in 2014... i was so mad. All those years and i never once heard a system test every December and June. I did however hear the december of 2016 system test, and 3 of the T128s are audible from my house, and i gotta say i love the sound of them. Again, i would have loved to hear what the thunderbolt 1000s sounded like, and thankfully there are videos of them on YT, someone tried to record as many Tbolts as he could before they got replaced.

[@Mortltd]

Awesome video.

[@PGMEagle]

P-10s and Allertors sound just about the same.

[@breadandbutterguy69]

I live there and listened to it once it's loud af

[@calumbrooknicolson]

Those particular sirens (the Three Mile Island ones) should be in ‘tornado siren madness’.

[@tickd8096]

So if you hear distant ominous noise run it's a nuclear meltdown (and possibly lots of other things)

[@kidsruledude]

Where was that first P-10? I think I've seen that one in person.

[@ThunderTrain2930]

I passed a T-Bolt in reading, and I'm pretty sure I passed a T-bolt and a T-128 next to each other.

[@BRISTOLFORCE2009]

Reading’s tbolt is a jailbar I’m pretty sure

[@ThunderTrain2930]

@@BRISTOLFORCE2009 this was a time I’d pass the glenside bolt all the time, but that’s since been removed, as well as the 13th and union bolt. The jail bar on reading city hall I believe is the only CD siren remaining besides a model 5 on the south part of town on a bakery.

[@ObamaTookMyCat]

+Patrick Rogers Yea about a mile or 2 west of Conowingo on rt 1 there is a grey Tbolt with a jailbar, guessing its been there forever, since the jailbar was phased out in the 60s, i saw it last year and i dont know if its still there, but there is a 128 next to it.

[@AwesomeDesertTrains]

! ObamaTookMyCat ! That better still be In service!!! If not I want that bad boy!

[@ObamaTookMyCat]

followed up on research, what i saw was wrong, the siren is saw was one of 80 sirens placed in a 10 mile radius around and was part of the peach bottom nuclear power plant system. They were all grey colored thunderbolt 1000s yes, all 80 of them. They were not however, jailbars. There are videos of them testing on YT, someone tried to travel around and record as many as he could. The system originates from the mid 60s, when the plant was first built. All thunderbolts were replaced by T128s as of 2013 was the start, and as off 2017 all thunderbolts are gone. Another person who inquired about them informed me on the siren forums that exelon is not interested in selling any of the old system, this includes peach bottom, TMI, and limerick. It is unknown where they took the thunderbolts after removal.

[@destisinawe1221]
