Hurricane Sandy May Score a Direct Hit On Spent Fuel Pools at Nuclear Plant
Preface: We hope and expect that the severity of the hurricane is being overblown, and that the nuclear plants in the Northeast will ride out the storm without any incident.
We noted Friday that more than a dozen nuclear plants are near Hurricane Sandy’s path.
Nuclear expert Arnie Gundersen says that there are actually 26 nuclear plants in the path of the hurricane, and that the spent fuel pools in the plants don't have backup pumps (summary via EneNews):
- You’ll hear in the next 2 days, “We’ve safely shutdown the plant”
- What Fukushima taught us is that doesn’t stop the decay heat
- You need the diesels to keep the reactors cool
- 26 plants in the East Coast are in the area where Sandy is likely to hit
- Fuel pools not cooled by diesels, no one wanted to buy them
- If recent refuel, hot fuel will throw off more and more moisture from pool
- Reactor buildings not meant to handle the high humidity
- Fuel pool liner not really designed to approach boiling water, may unzip if water gets too hot
- A lot of problems with allowing fuel pool to over
- Need water in around 2 days if hot fuel in pool
- The only fall-back if power is lost is to let fuel pools heat up
EneNews also reports that the hurricane is forecast to directly hit the Oyster Creek nuclear plant and that - while the plant is currently shut down for refueling - it still might very well have new, very hot fuel in the fuel pools:
Oyster Creek Nuclear Generating Station is located near New Jersey’s shoreline in an area forecast to take a direct hit from Hurricane Sandy: “The current ‘track center’ for the landfall path is central New Jersey pointing Sandy in a path that would hit Oyster Creek nuclear station.” -SimplyInfo
With Oyster Creek shut down for refueling starting last week, hot fuel may have been placed in the fuel pool quite recently.
The unit at Oyster Creek is the same as Fukushima Daiichi No. 1: “Oyster Creek is one of the oldest US nuclear plants and is the same design as Fukushima unit 1.” -SimplyInfo
Remember, Fukushima reactor number 4 was shut down for maintenance when the Japanese earthquake hit. And yet the fuel pools at reactor 4 are in such precarious condition that they pose a giant threat to humanity.
Hurricane Sandy is not very intense in terms of wind speed. But the storm is so large - 174 mile diameter of hurricane force winds, surrounded by 1,378 mile diameter of tropical storm force winds - that storm surges could be 11 feet high. In the area of Oyster Creek, the storm surge could be the highest ever recorded.
@But the real danger is a power outage. As Gundersen said today:
The biggest problem, as I see it right now, is the Oyster Creek plant, which is on Barnegat Bay in New Jersey. That appears to be right about the center of the storm. Oyster Creek is the same design, but even older than Fukushima Daiichi unit 1. It’s in a refueling outage. That means that all the nuclear fuel is not in the nuclear reactor, but it’s over in the spent fuel pool. And in that condition, there’s no backup power for the spent fuel pools. So, if Oyster Creek were to lose its offsite power—and, frankly, that’s really likely—there would be no way cool that nuclear fuel that’s in the fuel pool until they get the power reestablished. Nuclear fuel pools don’t have to be cooled by diesels per the old Nuclear Regulatory Commission regulations. I hope the Nuclear Regulatory Commission changes that and forces the industry to cool its nuclear fuel pools, as well.
This time of year, there’s a lot of power plants in refueling outages. And all of those plants will be in a situation where there’s no fuel in the nuclear reactor; it’s all in the fuel pool. Systems have been shut down to be maintained, including diesels, perhaps even completely dismantled. And in the event that there’s a loss of offsite power from the high winds from this hurricane, we will see the water in the fuel pools begin to heat up.
***
This isn’t like the Big Bad Wolf. They can huff and puff, and they won’t blow this plant down, especially a hurricane that’s only 85-mile-an-hour winds. It’s not a question of the winds from this hurricane blowing the plant down. It’s a question of the loss of offsite power. That’s exactly what happened after Fukushima Daiichi. The earthquake destroyed the offsite power. At that point, the nuclear plant relies on its diesels. And my big concern is diesel reliability and the fact that nuclear plants don’t have to cool their nuclear fuel pools off their diesels per NRC regulations. I think those are the two big concerns for Hurricane Sandy.
Obviously, the path of the hurricane could veer substantially, and may not hit Oyster Creek after all ... weather forecasting is not an exact science. But Gundersen argues that nuclear plants in Pennsylvania and New Jersey are in the most danger given current projections.
As we noted Friday, the Salem and Hope Creek plants in New Jersey are also near the path of the hurricane, as are the following plants in Pennsylvania:
- Peach Bottom
- Limerick
- Three Mile Island
- Susquehanna
Another concern is the Millstone plant in Connecticut:
EneNews summarizes the situation in a post entitled "Officials in Connecticut warn of giant 16-foot storm surge, with 15-foot waves on top of that — State’s nuclear plant directly exposed on ocean":
In a message sent to residents Sunday afternoon, [Norwalk, Connecticut] Mayor Richard A. Moccia warned of a 16-foot storm surge brought to land by Hurricane Sandy. [...] “I have declared a state of emergency in the City,” he said. “Coastal flooding from this event will peak at midnight on Monday night and will be worse than any flooding Norwalk has experienced in recent history. If you have ever experienced flooding before it is likely you will be flooded in this storm.” Moccia said that the storm will be equal to a Category 4 hurricane and will produce 16 foot storm surges.
“The mood during the meeting was tense as federal officials estimated a 13-foot storm surge for Westport [Connecticut] -– 3 or 4 feet higher that the inundation from Storm Irene last year,” a news release said. “This is an unprecedented storm,” said [First Selectman Gordon Joseloff], following his team’s briefing with federal and state disaster preparedness officials. “This will be a storm of long duration, high winds and record-setting flooding. Take Storm Irene from last year and double it.” he said. [...] The town is bracing for at least three waves of flooding, beginning with the high tide at midnight Sunday, the announcement said. [... An] estimated 15-foot wind-driven waves [...] are expected on top of the storm surge.
According to the Weather Channel’s latest map, a 6 to 11 foot water level rise is forecast for the Connecticut coastline. This is the highest increase of any area in the US. The state’s only nuclear power plant is located directly on the ocean, see marker ‘A’ below:
In July, AP reported:
Millstone Power Station, Connecticut's sole nuclear plant, is focusing on how best to guard against flooding and earthquakes to comply with tougher federal standards following the nuclear plant meltdown in Japan last year, the new chief of the power station said in an interview.
Millstone is assessing its ability to withstand flooding and "seismic events," Stephen E. Scace, who took over as site vice president at Millstone in January, told The Associated Press on Thursday. He expects upgrades and installation of new equipment in the next three to four years.

They won on September 11th...
In revenge for the Siege of Vienna.... on September 11th in case nobody but me notices the significance of this shit.... As was Benghazi on September 11th....
Never mind...
Repeats of Jersey Shore are on
knuckles, wanna' go for the Over/Under on when GW actually discusses Benghazi?
I'm goin' for the over.
- Ned
and you can pick the date ;-)
GW ain't touchin it till after 11/6...his current flock would desert him.
Pentagon ground breaking was 9 11 '41
Interesting speech was given on 9 11 '91
And when the plants ride out the storm safely? Where will the fearporn headlines be from GW?
Last week the Geo Wash bullshot was about Fukyaweenie vapors.
Today is is about water vapors.
Head to Home Depot and get a tarp. Two of them for extra security.
I know right?!
I'm so tired of hearing about unhappy shit!
I read zerohedge for fluff articles! I do not appreciate being bombarded by reality!
But the people that make money on nuclear power told me that it's safe!
The FDA just announced that radiation is good for you. Relax and enjoy the show.
you can trust the official experts, they are here to help.
In the meantime stay tuned to your TV
While we manufacture your false reality

Ill put my plans in a song
and as i destroy your way of life
ill make you sing along. -Payze Duez

George; do U want some info about rdioactive bears in Japan?
I don't touch such staff
it's okay we will just manufacture a false narrative/reality where flipper babies are chic
and where being a slave is sexy
Yeah...But if he/she/it does score a direct hit then it means there is a divine plan after all, no?
And I don't mean NYC is spared...
Why oh why, why in the world have all of these nuclear plants been built right about shore level?
OK I get it, about water, cooling, etc.
But right the Poop at shore level.
Brilliant.
Just plain brilliant.
Anybody ever give a risk assessment?
But Kunks, the probability of a 15 ft (or whatever) storm surge or a magnitude 5.5 on the Richter are 1 in a bazillion!
That's the whole point.... it's big enough that...
Oh never the fuck mind....
(same shit as when tasked with risk management that got a herd of sheeples asking why, the probability is.... and the VAR model... VAR, whata fucking joke...)
What a bunch of bull shit!
I live in southeast Florida, a Category 1 hurricane is a pussy.
You fuckhead liberals should worry more about Bernanke destroying our currency and less about this bull shit hurricane.
your comment was certainly not qualilty enough to be posted even once, let alone spamming it.
A weather system 1,000 miles wide is not bull shit, it's the fan orez. Sure you live in an area experienced with Hurricanes, most of the Eastern Seaboard and much of the inland regions however, do not. I wouldn't expect them to have the same building codes and common sense as someone who is in Florida or Texas or on the Gulf Coast.
Save your venom for the FED instead of attacking your fellow americans who are showing concern for a major weather event. How well would southern floridians cope with a weather system that dumps a couple feet of snow on your sandal toes and drops you in freezing temperatures for a couple of weeks?
Maybe, but what would a six foot storm surge from a Cat 1 hurricane with a weather system that stretches from Havana to Jacksonville do to Miami?
Improve the place?
Right, the reason the diesel motor's were abandoned politicially, was because under a test load for more than about 6 days, the motors failed and were of no use to cool any water. Rather than resolve the issue, the motors were removed from the required back cooling systems until another designed unit was installed. Which has yet to occur. Good luck again with defective energy policy, Today you can even sell shit to the fattie 50 and above crowd, it's called growth in the mid section.
-rates: dude ya gotta' clear your anal-cranial inversion issue. I mean really, diesels engine-generators support forced cooling of the core. The Poolz only need water added by a garden hose.
That is why you got my reddie.

Do your diesel pumps work just fine submerged under 12' of flood water?
Can your diesel pumps tolerate a 50:50 water / diesel "fuel mix" (along with whatever else particulate debris contaminates the unsealed diesel tanks)?
Do your diesel pumps have critical electronic infrastructure that cannot withstand submersion?
The fuel pools aren't the problem (apart from the slight tritium issue). The issue is will all the other infrastructure meet minimum operational needs for service and plant protection.
How many times in the recent past have Plant Operators NOT met the mandated safety standards.
... er ... we're talking about spent fuel pools, n'est ce pas?
I'm unfamiliar with "diesel pumps", perhaps you can describe how they work in a nuclear power plant? Or not.
Electronic infrastructure? wtf are you talking about?
You could answer your own question and tell us all, that would be the deal!

Well, it maybe 'cause I'm slightly more concerned with reactor coolant circulation, having seen what a failure of such can cause (you may remember Chernobyl??)
Emergency / Standby pumps are diesel powered. If there's no external power to operate the electric circulation pumps, diesel's the last resort.
Why would there be no electrical power? - Maybe 'cause water (probably quite conductive water at that - not sea water, but a mix of fresh / sea) does seem to create havoc with the sensitive, mainly microcontroller / SCADA based control and command systems within NP Stations. Failure of control usually means initiation of (manual) backup systems - and that's where the diesel pumps come in (or don't, as the case may be).
You'd be surprised at the thermal output from a fully shut-down reactor. ANY interruption of coolant is an immediate, and big issue. Coolant failure was THE principle cause of the Chernobyl event, and because it's happened once, it can certainly happen again.
they were built in an age even more ridiculous than our own, by people with no sense of the macroscopic phenomenology of things
and for those who did "SILENCE! UNDERLING!"
