Nation's oldest nuclear plant on alert

Source: Associated Press

By JOSH LEDERMAN – 21 mins ago

WASHINGTON (AP) — The nation's oldest nuclear power plant is on alert after waters from a colossal storm reached high levels. Oyster Creek in Lacey Township, N.J., was already offline for regular maintenance before Sandy, a superstorm downgraded Monday night from a hurricane, slammed the East Coast.

The Nuclear Regulatory Commission says an "unusual event" was declared around 7 p.m. when water reached a high level. The situation was upgraded less than two hours later to an "alert," the second-lowest in a four-tiered warning system.

Federal officials say all nuclear plants are still in safe condition. They say water levels near Oyster Creek, which is along the Atlantic Ocean, will likely recede within a few hours. Oyster Creek went online in 1969 and provides 9 percent of New Jersey's electricity.

...at plants like Oyster Creek they're more vulnerable because they have no way to keep the nuclear fuel cool in the reactor if the plant main power goes off and/or the diesel backup generators fail. They have about 2 hours to correct the problem which might not be possible in a hurricane.

In this case, the plant's fuel had been taken out earlier (but it's still really, really hot), and was placed it into the spent fuel cooling ponds. These ponds are extremely vulnerable because of the flooding (particularly when it's sea water). There is no artificial way to cool the outdoor ponds (The plant gets its cooling water from Barnegat Bay, a brackish estuary that empties into the Atlantic Ocean through the Barnegat Inlet). Although I believe Oyster Creek's cooling ponds are inside the building:





Many of these old plants have huge spent fuel holding ponds and many have as much as 30x the amount of spent fuel in them as Fukushima has, since they've been storing spent nuclear fuel there since they opened. In Oyster Creek's case, that would be 1969. This of course makes them particularly vulnerable to earthquakes, tsunamis, flooding and tornadoes. Like this one was last year during the 100+ tornadoes that struck in Alabama -- just 25 miles away from these pools at Browns-Ferry in Huntsville:

19. Wrong, they don't need the river to cool the storage pools.
Tue Oct 30, 2012, 01:07 AM

They need the river to cool the reactor under full operation. Not the same thing. The cooling pools can be maintained with city water if needed. There are lots of ways to cool the pools, as they don't take much to cool at all. A condenser providing 250 gallons per minute can do it.

They have a 30,000 gallon reserve tank. They have diesel fire pumps. Multiple. More than 5x the capacity that the standard cooling pumps deliver. They can accept pump inputs from fire trucks. And even if ALL of that fails, the pool doesn't flash over to steam in 5 minutes you know. It takes a while to heat a half million gallons of water, with fuel that is only giving off decay heat.

So, that's offsite power, and dual on-site diesels to drive the normal SFP's. There's multiple backup diesel on-site fire suppression diesels that can deliver in excess of 5x the normal cooling capacity. There's the 30k reserve tank. There are ad-hoc solutions like manual portable pumps and generators. And there is the heat carrying capacity of the water already in place (half million gallons).

The cooling water for the SFP's isn't even the fucking river. Where the hell did you get that crap? They use desalinized closed-loop water for that. The river is for cooling the turbine condensers.

SFP's: 250 gallons per minute.
Reactor: 40,000 gallons per minute.

THAT's why it's on the river, that's what it uses the river for.

And I did not happen to see your question. On fuel, a lot. Since the reactor started operating, which means, pretty much all of it. Depth of water? The correct/normal amount. There have been no reported pump failures, so the pools should be within spec on temperature and depth. I could probably dig enough to find out how deep they are, but what would that tell you?

Reactors 1-3 were in operation. Reactor 4 was offline for refueling and core shroud replacement.

Which of the four reactors went apeshit? Oh, right 1-3. The spent fuel pool on 4 evaporated partially a couple times, and there was some damage to the fuel. Still unclear if that was the cause of the hydrogen explosion, or if that was gas leaking into 4 from reactor 3.

Reactor four has been responsible for orders of magnitude less radiation release than reactors 1-3, which are, in fact, still leaking.

"Water level is rising in the intake structure due to a combination of a rising tide, wind direction and storm surge," the NRC said. "It is anticipated water levels will begin to abate within the next several hours." Exelon Corporation, the owner of the plants, said in a statement that there was "no threat to the public health or safety" from the situation. The plant also lost power, which is critical to keep spent fuel rods from overheating, but "the station's two backup diesel generators activated immediately," and it has two weeks of diesel fuel on site, Exelon said."

He was in fact dead wrong.

There were multiple (at least four) alternative pumps for cooling the spent fuel pools (none of which required the backup generators) and more than enough water on-site... and that's before considering the fact that any number of portable pumps could have served the purpose as well.

Oyster Creek Nuclear Generating Station

* The 20-year extension Oyster Creek was granted in 2009, was based on 30-year old environmental studies submitted with the application.

* The plant was leaking tritium at around the same timeframe that it's 20-year extension application was approved by the NRC.

* The NRC didn't comply with the Coastal Zone Management Act when they failed to obtain ''positive consistency determination'' from the state environmental agency, NJDEP.

* The NRC refused a petition from the NJDEP to take ''terrorism vulnerability'' in to account in considering re-licensing.


- I'm relatively certain that at the time the NRC extended Oyster Creek's license for another 20 years back in 2009, they all said: "What's the worst that could happen, eh?"

- Which is still too far away to me. It's the oldest nuclear reactor running (1969) in the US. And it operates a single Mark I boiler-reactor, just like the ones still spewing radiation all over the planet in Fukushima. Leaving it to operate that long I think is really pushing it.

Tue Oct 30, 2012, 01:10 AM

He was less a whistleblower than a control freak and from the sound of it, a bit unstable too.

"NRC Inspector General Hubert Bell released a report in June that alleged Jaczko “controls information” provided to the other NRC commissioners by designating issues as administrative matters, which he has control over, rather than policy matters.



“Because he acts as the gatekeeper to determine what is a policy matter versus what is an administrative matter and controls information available to the other commissioners, they are uncertain as to whether they are adequately informed of policy matters that should be brought to their attention,” the report, which was requested by House Republicans, says.



The report also raised questions about Jaczko’s handling of the decision to stop work on a multi-part evaluation of the Yucca Mountain nuclear waste repository in light of the Obama administration’s decision to abandon the long-delayed project.

"

It's not whistleblowers we need so much, not with the all the facts out there for everyone to see. Oyster Creek is a case-in-point, literally a poster child of the dangerous leaking nuclear plant breaking the rules and sometimes the laws -- examples of which can be found all over the world. And when considering this list of aged boiler reactors (26 of which are exactly like the ones at Fukushima) are located right here in the good ole USA-'Murica. So our chances for replicating this insanity are outstanding!

And these old rickety pot boilers are around the same age (40+ years or more). Some have recently been given 20-year licensing extensions. ''What could be worse'', you ask?

How bout: The NRC must decide shortly whether to consider 80-year extensions. Because they're either going to have to continue granting extensions for these aging cracking-concrete behemoths, or by 2020 most of them will be coming offline. That is if they haven't already destroyed themselves (and some of us), before then.

Despite all the hyperbole about 'cracking concrete', most of these reactors are just fine. Problems are twofold:


1. bad inspection processes, like the RPV that almost corroded through. That was an inspection fuckup. Entirely predictable, and not related to the age of the hardware.
2. The world has moved on. Replacement electronics are not exactly off-the-shelf hardware. But that's ok, because the people who work on these are perfectly capable of building what they need.

30. U.S. nuclear plant declares "alert" after Sandy storm surge
Tue Oct 30, 2012, 11:12 AM
Oct 2012

... The alert -- the second lowest of four NRC action levels -- came after water levels at the plant rose by more than 6.5 feet (2 meters), potentially affecting the pumps that circulate water through the plant, an NRC spokesman said late on Monday.

Those pumps are not essential since the 43-year-old plant was shut for planned refuelling since October 22. However, a further rise to 7 feet could submerge the service water pump motor that is used to cool the water in the spent fuel pool...

... The used uranium rods in the pool could cause the water to boil within 25 hours without additional coolant; in an extreme scenario the rods could overheat, risking the eventual release of radiation.

Exelon spokesman David Tillman said the plant has "multiple and redundant" sources of cooling for the spent fuel pool. He said he did not know whether the service water system was operational at the moment...

... Constellation Energy Nuclear Group's 630-MW Nine Mile Point 1 nuclear power reactor in upstate New York did shut down due to a problem putting power onto the grid, although it was not clear whether the trouble was related to the storm, the NRC spokesman said... The relatively small 636-megawatt Oyster Creek plant also experienced a "power disruption" at its switch yard, causing two backup diesel generators to kick in and maintain a stable source of power, Exelon said. Tillman said another Exelon reactor at the Limerick facility in Pennsylvania was reduced to 91 percent power after Sandy caused a problem with the condenser.
