EMP ATTACK ON U.S.

[user 7704]

I saw on Breitbart about concerns of an EMP attack via satellites. North Korea is the culprit of course.

here's a lil something i found..

EMP ALERT: 2 N. KOREAN SATELLITES NOW ORBIT OVER U.S.
'The threat continues to race, hare-like, at an alarming rate'

[user 7704]

Damn auto correct. I put in EMP 3 times and it shows up employee. Lol

 

[jimLE]

and thats why i check,and recheck my spelling when i use my smart phone..

I'm looking at the SATs right now, tracking on Satflare and N2Y0, ones over the middle east and the other over Europe not the US, I view Peter Pry comments as skeptical but agree to the urgency of hardening our defenses

 

[Maverick]

In fact KMS 3-2 trajectory isn't even passing over the US !!

Hmmmm. I was just going by what's on Breitbart. It is something to think about.

I think the term "smart phone" is a contradiction in terms.

Yes, it is certainly something to think about unfortunately

Very cool.

well I can't stop it from happening so,,,,I will just have to wait and see if it happens

 

[Prepqueen30]

Ya ive been learning about emps....very scary. Speacially if its a nuclear kind. Not much time to get cover. At all. Last night i read about cherynoble and fukashima, interesting...horrible. then today a plutonium site in washington had a tunnel collapse.. Evacuation hundreds of workers. Hopefully that can get resolved. What the hell was humans thinking??? Oh they werent! Greed. That is all.

 

[Prepqueen30]

If we got hit with an emp and it took out our power grid. All the nuclear power plants would burn up and catch fire, explode and yes like kim said the u.s would be nothing but ashes. fukashima was hit with a tsunami that knocked out their power grid. What we have is the result.

 

[lonewolf]

fukashima didn't explode, it just shut down, sure there is now toxic material in the sea of Japan.
nuclear warheads these days are smaller than in the cold war days, because of better targeting they don't need to be, unless your in the blast zone you've got a good chance of surviving, a nuclear air burst wouldn't even kill anyone but it would cause an EMP that would take out the infrastructure and leave the survivors without power.

 

[Prepqueen30]

I know fukashima didnt blow up. But its burning a whole through the bottom. Leaking into the ocean. thats a good thing then if theres no fall out. Thought i read there was fallout with a nuclear emp.

 

[lonewolf]

I think a lot depends on weather conditions and prevailing winds. but whatever, its never good news.

Try reading a novel called 'one second after'. Very incitefull book.

The hydrogen sure did blow up. Took the top of the building off. Maybe not a core meltdown, but pretty nasty anyways.

I was a fan of clean neculear power before Fukushima. I thought they could just seperate the rods in an emergency and put the things to sleep. Not so, as we now know. Sure they have generators, but in a prolonged emergency the likelihood of power loss is too high. Now, also learning of the amount of toxic byproduct, it just isn't worth the risk. Solar is still far off, but if humans were smart we would be working our ***** off to make it happen as soon as possible.

 

[user 7704]

I do have a small Faraday box for batteries and walkie talkies, etc.

There would be very little fallout from a HEMP, in Fukushima the water took out the generators from the tidal wave effectively shutting down the cooling pumps, under normal circumstances the fuel would be removed and put in a cooling pool, in this pool it takes 10yrs to cool the fuel enough to place in dry storage. Nuclear power plants depends on outside electricity to keep the plants from going in to the 'china syndrome' The question is, how much fuel is available to run the onsite generators? I can tell ya, it's not 10yrs worth.

 

[lonewolf]

I don't like nuclear-power or weapons, I wish we could go back and stop this thing ever being made.
what with Hiroshima and Chernobyl and 3mile island, I don't trust any of it. now Fukishama, okay that was a Tsunami but it still made a mess of it.
we left our last place when they announced a new nuclear power plant was being built 15 miles directly down wind of our location.

Fukushima was a case study in short sighted planning. One of those cases where the engineers and officials responsible need to be strung up by their thumbs and left for the crows to peck out their eyes...

Even though Unit 1 had a passive cooling system, electricity was necessary to control the passive cooling system. The IC (isolation condenser) was operated intermittently, and the valves were closed at the time of the tsunami. The emergency generators and batteries were in the basement, which flooded. With no electricity, the IC valves could not be opened.

Units 2 through 6 had active cooling systems (water has to be continually pumped). Units 2 and 4 had emergency generators on a hill which was not flooded. Those generators could have provided power for all the cooling pumps in all the units, but the switching stations that sent power from the generators to units 1 through 5 were shut down by the tsunami. Only station 6 could get power to the cooling pumps.

The vulnerabilities were known. A 2008 study warned of the danger from a 10 meter tsunami, and proposed steps to correct the vulnerabilities, but officials insisted that such a risk was unrealistic and ignored the study.

Better designs have passive cooling systems that can operate without any electricity at all. In fact, they engage automatically when the power goes out. And they have water towers that provide 72 hours of emergency cooling water that flows by gravity through the reactor to keep the reactor cool until it can be shut down.

We only have 4 modern passive systems in the US (not operational yet), I don't see all the existing reactors being retrofitting in older plants with the newer reactors similar to the AP1000 (GenIII) and with Westinghouse going through bankruptcy even adds more uncertainty in the US, Hopefully Toshiba can carry Westinghouse through the troubling times? unless we start using a chinese built CAP1400 (in part with Westinghouse help during the design phase) A side note, three mile island had a passive cooling system in one of the reactors that failed to cool and chernobyl had a passive safety system as well.

Between DECOM of older plants and building newer plants with a modern passive system the cost would be astronomical, 5yrs to DECOM and 6 years to build new plants after approval. Almost all 99 reactors in the US are GenII, the only GenIII plant in operation (2017) is in china built by Westinghouse with CAP1400 (GenIII+) going online in the near future (china)

Either way I don't see a lot of GenIII going online anytime soon since GenIV reactors are in development right now, a lot of bad can happen in the next 20 years

 

[DrHenley]

Some Gen II BWR reactors have Isolation Condensers like Unit 1 at Fukushima. With an IC, water boils in an evaporator in the reactor, and is driven up by the pressure into a condenser above the reactor, where the heat is transferred into a pool of water open to the atmosphere. It then condenses and gravity brings it back down to the reactor.

 

[Maverick]

I'm wondering if they can add new passive system to existing reactors or does it require a whole new plant?

 

[DrHenley]

Yes, Gen II BWR systems can be retrofitted.

PWR reactors are a whole different ball game. A PWR reactor is self-regulating. The hotter they get, the slower the reaction becomes. And PWR reactors have passive SCRAM mechanisms. The control rods are held up by electromagnets, and if they lose power, the control rods just drop, shutting down the reactor.

 

[Brent S]

With prepping we all say have a backup for your backup. With these power plants that redundancy needs to be multiplied by 4 at least IMHO.
