Natural Gas Fired plants are 10 times larger, around 25800 MegaWatts. STP is just 2500 MW.
Gas and coal plants are shutting down for safety. But the dying nuclear industry refuses to give up even a day of profits, as Biblical storms pound Texas.
The "Design Basis Flood" of which engineering is done to protect from is 40.0 Mean Sea Level. See second screen cap down. Bay City is the nearest River Gauge Station. They are predicting over 50 ' Mean Sea Level. But no plans to shut down this nuclear plant.
The Colorado River (of Texas) Basin is huge. In the NRC Flood Risk Control documents they try to minimize the area of the Basin to make things "look better", They cut the basin size by almost half. My calcs show below show 13,389 Trillion gallons of water to hit that basin, using the proper area.
Update: STP Nuke Plant In plain english…
We know that the STNPPL (South Texas Nuclear Power Plant Lake) WILL have problems….
We also KNOW the smaller "loop pond" will be inundated with flood waters…
And the flow pipe exit and intake gates in the small pond will be under water…
Seems clear this is a situation where running those reactors under those conditions is not only wrong it's a violation of both NUREG and state/federal law…

If you don't believe that look up willful child endangerment in the criminal code…

And endangerment of grandparents too..

Don't sit idly by while a major potential nuclear threat looms!!!!
SHUTDOWN THE STP NUCLEAR POWER PLANT NOW!!!!

The U.S. Nuclear Regulatory Commission (NRC) is granting exemptions from certain portions of the acceptance criteria for emergency core cooling, and the general design criteria for emergency core cooling, containment heat removal, and atmosphere cleanup for the use of a risk-informed analysis to evaluate the effects of debris in containment following a loss-of-coolant accident (LOCA) for the South Texas Project (STP), Units 1 and 2, located in Matagorda County, Texas, Docket Nos. 50-498 and 50-499, respectively. The exemptions are in response to a request dated June 19, 2013, from the STP Nuclear Operating Company (STPNOC, the licensee) related to STPNOC's proposed approach to resolve a generic safety concern for pressurized water reactors (PWRs) associated with potential clogging of emergency core cooling and containment spray system strainers during certain design basis events.
DATES: The exemption was issued on July 11, 2017.

Here's how to make it look good on paper…You all know if I took the time to look these "scientists" up, what would turn up…
https://experts.illinois.edu/en/publications/risk-informed-resolution-of-generic-safety-issue-191
This paper summarizes the elements of the integrative framework including PRA and the CASA Grande program, as well as the input parameters, assumptions, methodology, and results of the STPNOC analysis. The results show that the risk of core damage or large early release related to the concerns raised in GSI-191 in the as-built, as-operated design for STPNOC is very small (as defined in Regulatory Guide 1.174).

"safety concern for pressurized water reactors (PWRs) associated with potential clogging of emergency core cooling and containment spray system strainers during certain design basis events.
DATES: The exemption was issued on July 11, 2017."
Now let's all imagine the level of leaves, limbs, yard items, cans, plastic wrappers, building materials, car parts and other simple trash that is washing downstream NOW!!! (after the largest flood in recorded history).
All this "stuff" (floating and submerged) is being carried down this river from points as far north as Austin and beyond… And it's all in that water that is inundating that nuclear plant, it's cooling supply pipes and many other systems…
This ain't no dress rehearsal folks…
SHUT DOWN THE STP NUCLEAR PLANT NOW!!!!!
-
Oh, "potential clogging of emergency core cooling and containment spray system strainers during certain design basis events". Would a 'certain design basis event(s)' be a FLOOD? Seems clogging and floods do seem to go together(there is a lot of junk in the water then to clog up filters!). And define 'very small'..wait we have go go find that Regulatory Guide 1.174 to see what they mean.
Hope STPNOC has it right..seems strange exemption was granted finally after a 4 yr wait..just before major hurricane season hit..and while the GOM season was beginning.
Are lawyers worried, no, professional courtesy
The ratfarmers are pee'oed the nuclear plant is holding up in the storm. STEPS built to be the last tging standing. Ratfarmers can just lump it. People need electricity during times of crises when other sources are knocked out.
ReplyDeleteThe issue is flooding. Of course they will in general handle high winds unless their primary substation is coated in salt like Pilgrim.
DeleteSites like STP can handle Beyond Design Basis Events, a Fukushima add on. NRC would have mandated a shutdown if risk warrants it. Alot of people dont understand likelihoods relative to realism.
DeleteNuclear plants, despite the bs we hear about how "safe" they are, will be the death of this planet. Fukushima was one. Others will fail also, Murphy's Law. Yet we keep building and licensing more of these potential death factories.
ReplyDeleteAns was your degree in nuclear engineering or lesbian alternative interpretive dance Skippy?
DeleteComparing Fukushima to any US plant, even the 23 GE Mark Is is apples and oranges. People need to study more accurate information not their beand of dkhead antinuclear bs science
DeleteLet's shut down everything we don't understand. What the article (and I'm using that term loosely) failed to mention while spewing doom and gloom prophesies, is the effect that any of the water has on the oberavolity/availability of cooling and safety systems. Please re-write as an informed, balanced article, rather than a nonsense, finger-pointing, hyperbolic piece of crap.
ReplyDeleteWell I asked STP tech staff about little things, like what MSL flood was their suppression pool heat control systems protected to. And they told me they couldn't release that information as it might be a security concern.
DeleteThe design basis flood for the plant is 40 MSL. So why expect that they designed to higher than that? But the flood level is expected to be 52 MSL
Doesnt this seem logical to be concerned. No doom and gloom, just shut the darned plant down for 3 days, or go to Mode 3 to allow a quicker restart, whatever, so something rather than drunk fraternity boys doing high fives because "we are running"
The plant is run by true professionals. You would know it if you spent some time doing what they do. They are highly skilled, highly trained, and live under a microscope of scruitiny. Still the job isnt for every technically bent person. Having intimate understanding of this operating environment and culture, they are truely heroic publically minded servants. Give them a break.
DeleteNo they aren't professional at all. NO PLANNING whatsoever for flooding.
DeleteThe engineer had to scramble around foraging for FOOD for the STP crew because - duh - no one planned on crew getting stuck inside by massive flooding that had DAYS of warning before hitting.
M.A. new article -
" In a 2015 NRC document, Raihan Khondker is listed as STP Engineer Sr, Equipment Reliability. According to his linked in page, his experience includes maintenance, and corrosion engineering. The fact that he had to drive through flood waters to bring supplies because engineers were running out of food, according to the article, speaks volumes about the disorganization and lack of planning. ".
Big headlines it was coming Aug. 24 -

Your local pizza-chain outlet has better planning.
"heroic publically minded servants" do not threaten their neighbors with death, pregnancy termination, infant death, cancers, wrecked DNA, shorter life spans, dementia, and nuclear explosion.
Publicly minding people work tirelessly to shut down these giant unexploded bombs in their community.
You have no clue. You dont know what goes on in the control rooms and emergency ops centers. All you have is popular press, which isnt much.
DeleteWrecked dna? From deminimus rad levels? You obviously are not formally schooled in radiarion sciences and protection. People like you dit around your campfires reminiscing about the 60s and protesting anything that isnt hippie leftist garbage. I bet you never held a real job.
Oh hilarious, rather than presenting an argument the Gov Troll Turd throws down the "Dirty Hippie" card.
DeleteNo troll. But you can do alot worse in gvt. Be glad Im where I am at, having your back.
DeleteI don't need you on my backside if those plants where all decom'd
DeleteOK, Turd, we will label you a "true believer", which is not a complement in this regard.
Deleteadding to my blog post on it ....
ReplyDeletehttps://lasinkhole.wordpress.com/2017/08/25/harvey-nnps/
I didn't see any add, looks very short article then mining awareness.
DeleteThey are all in the COMMENTS to that post.
DeleteMining Awareness has same thoughts about S. Texas NPP ....

No clue. Get one. The plants are operating for a reason.
DeleteYou should thank God those affected by the hurricane have a steady supply of reliable, safe electricity. But you eull never see it that way. Im reminded why the antinuclear position is so illogical and framed from worst case scenarios that never lived up to the hype. Going on 60 yrs now. Surly youve had the chance for oroper knowledge.
DeleteTurd, surely you know the concept of Expected Value?
DeleteThe positive value times the percent chance the good thing happens, plus the negative value times the chance the bad thing happens.
Running the plant was a stupid proposition, a bad bet. Insanity worse than power drunk fraternity boys
Im a poker player. I understand EV all too well. You need to use the correct numerical value for likelihoods. The EV is more than positive for nuclear plants when actual not inflated numbers are used.
DeleteI have a small pocket pair, you have AK in holdem. What is the EV for you preflop? Assume a normal game. What if I had AA?
Ans: next post
How do you calculate EV when the negative outcome is an UNACCEPTABLE loss? If you win, you get $1M but if you lose, you lose your life.
DeleteStill like to play the game?
