I was working at a substation at Calvert Cliffs a while back that was located behind a shooting range. They stopped shooting so that we could get back there, but they must have forgotten after a couple of hours because they started opening up with the automatic weapons again. I'm glad they had that big ass hill of dirt at the end of their range.

11/19/2007 6:23:01 PM

Is this the turbine hall? That is one clean and organized turbine hall.

11/19/2007 8:47:53 PM

Brunswick's turbine deck looks as clean as that

[Edited on November 19, 2007 at 8:50 PM. Reason : but it is a BWR so the steam is full of N16]

11/19/2007 8:49:00 PM

on inspection days?

11/19/2007 8:50:32 PM

I have no clue where the top pic is but the bottom is Brunswick. And the turbine deck looks really clean all the time, except during the outage when the turbine is laying around everywhere

11/19/2007 8:51:39 PM

i bet you have to wear a banana suit to work on the turbines, since it's a BWR and all

look, BWRs just sound dirtier than the other designs okay.

11/19/2007 8:53:37 PM

Na, 30 sec to a 1 min after you shutdown the turbine deck is all pretty clean. It is just the N16 production that keeps most of the are a locked hi-rad area.

[Edited on November 19, 2007 at 8:55 PM. Reason : think the holdup tank with the PULSTAR]

11/19/2007 8:55:20 PM

dude, the NCSU reactor is a 1 MW piss-ant that runs on average like 5% of that.

And yeah, the N16 has like a 7 sec half life I've heard. But still, compared to the campus reactor, you have leakers, and all kinds of junk that gets activated. I still wouldn't go like a take a nap on top of the dry turbines.

11/19/2007 9:16:52 PM

yes yes, I would not be very concerned with N16 30 minutes after shutdown.

11/19/2007 9:33:42 PM

^^^ Back when I was an operator we were at 1MW full power a lot of the time...

11/19/2007 9:49:17 PM

^^ I almost never see the chimney putting out steam. And even a lab or two that did control rod insertions / removals (and corresponding reactivity calcs) only saw the reactor go up to 750 kW or so.

And plus, it's not "on" except for 8-5 is it? While I'm sure that nothing would happen if it was just left running while no one was here, I'm pretty sure the NRC wouldn't like that.

11/19/2007 10:09:33 PM

i took in a few milirems earlier this year when i was touring a nuke plant to gather information to put together an rfid proposal - i don't know how people do it day to day

11/19/2007 10:11:32 PM

The chimney NEVER puts out steam, because the primary coolant never goes above 120 F. The secondary inlet to the HX is usually about 80 or so. And both at atmospheric. So whatever steam you saw must have been from something else...

And yeah, it's never on except when the SROs are there...8-5. So I guess if you average the 24-7 power level is would be pretty low.

11/19/2007 10:11:52 PM

pumping out 995 Gross Megawatts 24 hours a day, w00t!!!!

11/19/2007 10:25:14 PM

okay, i didn't know anything about how the chimney worked here. Still, if it's for cooling, it should occasionally produce some sort of cloud - i.e. the cooling towers at a commercial reactor never get close to 212. And even at 1/3000th the power, it could still be a modest cloud...

You'll never see anything putting out steam because you can't see steam.

"This photo illustrates the Turbine hall in a BWR facility. Closest to us in the photo is the exciter, generator, 3 low pressure turbine stages, and the high pressure turbine. On either side of the turbine can be seen the moisture-separator reheaters. Note the shielding around the turbine. Shielding is needed because the steam from the BWR contains radioactive N-16, which decays with 7 second half-life."

Ahaha, fucking idiots. The PULSTAR rector goes to 1 MW a lot. They have to have it running at power for a lot of the experiments and isotope generation they do. God people talk out their ass about nuclear stuff all the time.

I've brought it up to power myself as part of an undergrad lab. There's never steam since it's a pressurized water reactor with no secondary (steam) side. If there was boiling in the pool they'd probably scram the thing anyways. Also 1 MW thermal power is nothing. Commercial reactors are 30 some percent efficient so a 1000 MWe reactor is about 3500 MW thermal.

it is most certainly not pressurized.

wats MWe vs MW?

11/21/2007 4:20:10 AM

Yeah, but it's meant to model a PWR. It behaves like a PWR in that there is no bulk boiling and in how the system is controlled (control rods on top.)

^^Megawatts electric.

11/21/2007 4:21:34 AM

MWe = megawatts electric, i.e. electric power output.

MW (megawatt) is a measure of energy generation / consumption rate (called power)

To produce a MW of electrical power output using a thermal power cycle takes somewhere between 2 and 4 MWth (megawatts of thermal energy).

11/21/2007 4:22:40 AM

dnl what about geothermanl or solar with better technoloogy were not too far away from higher effienciny tech

11/21/2007 4:23:07 AM

nuclear power is the way to go

11/21/2007 4:23:43 AM

limpy- is that loss from turbines or merely conversion (like joules to calories type thing)

11/21/2007 4:24:41 AM

Geothermal, solar, wind, etc. are not cost effective and don't have the capacity that is in demand.

11/21/2007 4:24:58 AM

^^ It's thermodynamic efficiency. A lot of it is entropy losses and losses to the environment. Nuclear steam systems tend to be about 30 some percent efficient because the zircalloy cladding they use can not handle extreme high temperatures (like super-critical-water systems) and so because of that and some other factors they're not super-efficient steam systems.

11/21/2007 4:28:51 AM

it still amazes me that coal and nuclear power plants still use a loth of the same tech

11/21/2007 4:29:49 AM

^^ Yeah they can't get the temperatures up high enough because the zirc disintigrates, reactos and/or glassifies in high temperature situations depending on the pases of water you're dealing with. Super-Critical-Water-Reactors would be great, but the high temperatures and super-critical fluid int hem would dissolve current fuel assemblies.

^Well advances in coal plants have been examined for use in things like the proposed (it's never going to happen though) SCWR.

11/21/2007 4:31:08 AM

Yeah the method for energy conversion in a fuel-consuming power plant doesn't change until you start talking direct conversion in fusion reactors- harnessing excess charge directly for current.
