	Th232 has a half-life of 14 billion years
18:47:18 From Galaxy A10e to Everyone:

	Why nuclear power is not a good global warming tech. 1) cooling water a yuge source of direct warming, raising the temperature of even major rivers a couple of degrees. 2) tech hugely fossil fuel intensive gro. starting plant to decommissioning.
18:49:12 From cbarcus to Everyone:

	Lots of ways to do cooling. Raising the operating temperature improves the efficiency.
18:52:16 From cbarcus to Everyone:

	Waste heat from industry may become a concern for climate eventually, but consider how much extra power the planet is receiving (radiative forcing imbalance) from the increase in GHGs. Lowering GHGs gives more headroom for waste heat. Now, atmospheric carbon is essential for life, so there is an optimal range for concentration for civilization. I think the current goal is 350 ppm.
18:52:38 From cbarcus to Everyone:

	Current is 415 ppm or so, see Keeling Curve.
18:54:39 From Galaxy A10e to Everyone:

	For good technical info from independent sources: www.fairewinds.org, www.beyondnuclear.org
18:57:27 From Galaxy A10e to Everyone:

	Why no wind/solar in America. Koch's brothers ocked rooftopsolar in county building codes-restraint of trade.
18:57:47 From cbarcus to Everyone:

	How about the scientific and engineering communities? How about our educational institutions and technical press? Insular thinking can drive us to extinction. Consider the fundamental American values of inclusive diversity and truth.
18:58:29 From Galaxy A10e to Everyone:

	So before we build any more nuke plants, let's fully build out wind/solar options.
19:00:15 From cbarcus to Everyone:

	No. That is not going to happen. We are in a race against time, and we are marshaling a strategic response the this existential threat. That means we will optimize around power growth, strategic materials, energy flow, etc. It is far more complex than the public has been led to believe.
19:00:56 From Galaxy A10e to Everyone:

	The other day NBC celebrated decommissioning of Three Mile Island. There was a lot of chronic illness in surrounding communities due to extensive release of high level radiation from containment to prevent hydrogen explosion. Desantis lied shamelessly.
19:01:38 From Galaxy A10e to Everyone:

	saying there were no illnesses.
19:02:42 From cbarcus to Everyone:

	There remains a great deal of confusion around health physics. Now, there may have been some injury from TMI’s release, especially from those short-lived isotopes early on.
19:05:14 From Galaxy A10e to Everyone:

	Didn't really hear about epidemic of thyroid cancer In Tokyo did you?,Nope because the Gov't threatened physicians who did talk about it with the loss of their medical licenses.
19:05:19 From Doug Rodgers to Everyone:

	From Wikipedia -- The health effects of the 1979 Three Mile Island nuclear accident are widely, but not universally, agreed to be very low. The American Nuclear Society concluded that average local radiation exposure was equivalent to a chest X-ray, and maximum local exposure equivalent to less than a year's background radiation.
19:05:27 From cbarcus to Everyone:

	Anyway, we are moving away from those LWR designs…
19:06:05 From cbarcus to Everyone:

	You misunderstand thyroid cancer incidence in Japan from Fukushima.
19:06:51 From Galaxy A10e to Everyone:

	Increased levels of leukemia within 5 mile radius of nuke plants. Gotta keep them spent fuel pools cool too.
19:08:20 From cbarcus to Everyone:

	Incidence of thyroid cancer in Japan: https://pubmed.ncbi.nlm.nih.gov/28954584/#:~:text=The%20large%2Dscale%20ultrasound%20screening,cohort%20of%20approximately%20300%2C000%20subjects.
19:08:34 From Galaxy A10e to Everyone:

	The info you give on TMI and disease is BS
19:08:46 From cbarcus to Everyone:

	GA: you do not know what you are talking about, please desist.
19:09:51 From Galaxy A10e to Everyone:

	There is an article at by an epidemiologist atwww.alternet.org archived.
19:11:21 From cbarcus to Everyone:

	Please remember, epidemiology is a tool, and only part of a larger scientific picture in the quest for understanding.
19:12:25 From Galaxy A10e to Everyone:

	So let's build out full wind/solar potential and then go to natural gas-still better than nuclear.
19:13:03 From Galaxy A10e to Everyone:

	Facts in disease cancers are provable.
19:13:12 From cbarcus to Everyone:

	GA: in short, that is suicide…
19:13:26 From cbarcus to Everyone:

	see: Cancer as a Metabolic Disease
19:15:12 From Galaxy A10e to Everyone:

	And again there is the yuge direct warming problem.
19:16:45 From Galaxy A10e to Everyone:

	You are not responsible to the disease causing vhallenge. Minimization does not change the problem.
19:17:08 From cbarcus to Everyone:

	GA: you do not know what you are talking about. You are regurgitating nonsense cooked up within the insular part of the Green Movement. It was so bad, a schism developed to support nuclear power.
19:17:36 From Galaxy A10e to Everyone:

	fact check at the two websites.
19:20:27 From Galaxy A10e to Everyone:

	Fine, just so the GD plants are nowhere near me.
19:21:06 From Galaxy A10e to Everyone:

	There's idikt paid liars everywhere.
19:21:42 From cbarcus to Everyone:

	Actually, you will want to live close to some of this advanced technology…there will be huge societal benefits, and decarbonization will be accelerated. Will help in our efforts to address global poverty.
19:22:57 From Galaxy A10e to Everyone:

	And now the ratepayers get to pay off debt on an unfinished plant??!
19:23:15 From Galaxy A10e to Everyone:

	South Carolina
19:24:08 From cbarcus to Everyone:

	GA: remember, if advanced nuclear turns out to be an economic failure, we are finished…but do not fret, it will not be…we have been sitting idle on this potential technology for decades…it will be awesome.
19:24:42 From cbarcus to Everyone:

	SC situation is not scalable…that is not the future.
19:26:04 From Galaxy A10e to Everyone:

	Taxpayers pay for long term storage and any accidents. Not included in pricing.
19:26:49 From cbarcus to Everyone:

	Yes it is. Again, you do not have a clue what you are talking about. Do not feel too bad, the issue is widespread.
19:27:26 From cbarcus to Everyone:

	Next generation waste storage will save more than an order of magnitude in its contributed cost. See: Deep Isolation.
19:27:35 From Galaxy A10e to Everyone:

	No it's not and neither is decommissioning $2bil. in germany.
19:27:56 From cbarcus to Everyone:

	GA: I am talking about the US.
19:28:15 From aleta_greenway@hotmail.com to Everyone:

	which cities in the USA are already using this technology, how do they like it, how do taxpayers like it, etc.   ?
19:28:28 From cbarcus to Everyone:

	Decommissioning can be incorporated into the design of the system, saving both cost and time.
19:29:09 From cbarcus to Everyone:

	Advanced nuclear is currently in development…listen to the presentation…LOL. signing out
19:29:52 From Galaxy A10e to Everyone:

	Same difference $2 bil.. The Herman's won't cut corners do it 9n the cheap like you. Hey, see that waste dump in east St Louis. Still on.fire??!
19:31:10 From Galaxy A10e to Everyone:

	Not interested in complex high risk tech that no insurance company will cover.
19:37:55 From Galaxy A10e to Everyone:

	What happened when japanses sodium cooled reactor blew up and sodium exploded and caught fire??!. Does coolant solidify??!

	Design taken from ORNL by Chinese Academy of Sciences…they came for a visit some years ago.
19:45:17 From Cyndy Bratz to Everyone:

	What about Terrapower’s traveling wave reactor?  Are you familiar with it?  Status in the US?
19:46:00 From cbarcus to Everyone:

	Natrium was mentioned…
19:48:06 From cbarcus to Everyone:

	I think the references to ‘inherent safety’ were in reference to new passive safety measures that eliminated some troublesome high impact failure modes.
19:50:17 From Galaxy A10e to Everyone:

	Theoretically eliminate. .  . .
19:50:52 From cbarcus to Everyone:

	GA: for instance, liquid fuel reactors cannot melt down…
19:51:14 From Galaxy A10e to Everyone:

	They can v
19:51:38 From Galaxy A10e to Everyone:

	they can go to hell in other ways.
19:52:25 From cbarcus to Everyone:

	GA: what other failure mode are you worried about?
19:55:39 From Galaxy A10e to Everyone:

	steam pressure steam plants 200 psi: welds restraining 800 psi need to be A LOT better.
19:57:02 From Gary Nelson to Everyone:

	Recording Stopped???
19:57:53 From cbarcus to Everyone:

	Of course, the system has to be designed to avoid steam explosions, but water does not have to reside in the primary loop, and also does not need to be involved in the electrical generation process either…
20:01:34 From Dave Clive to Everyone:

	Ships using 1600 psi steam have been in use sine the 1840s.
20:01:37 From Cindy Jayne to Everyone:

	For new modular reactors, do you have any data on the carbon footprint of the production of the plant, and how that impacts the net carbon footprint of the electricity generated?
20:01:57 From Dave Clive to Everyone:

	I meant 1940s.
20:01:58 From Galaxy A10e to Everyone:

	Then what will be in the primary loop?
20:02:22 From cbarcus to Everyone:

	GA: You have not been listening to the presentation: 🙁
20:03:16 From Galaxy A10e to Everyone:

	So what? I am unalterably.opposed to both nuke tech and fusion tech
20:04:00 From cbarcus to Everyone:

	GA: yes, and that is also why you do not understand what is being discussed with regard to poverty, energy, economics, and climate.
20:04:25 From Galaxy A10e to Everyone:

	So answer my question.
20:04:39 From cbarcus to Everyone:

	Recording missed part of the fusion presentation.
20:05:41 From Galaxy A10e to Everyone:

	carbon footprint of mining processing, and construction.
20:06:03 From cbarcus to Everyone:

	Deep decarbonization is a strategy to remove carbon emissions from the supply chain. SMRs will be carbon free, and so will everything else…except for those products made with captured carbon…
20:06:29 From Galaxy A10e to Everyone:

	Still have massive direct warming problems.
20:08:47 From Doug Rodgers to Everyone:

	Over its life-cycle, nuclear produces about the same amount of CO2-equivalent emissions per unit of electricity as wind, and one-third that of solar. (according to Google search)
20:09:58 From Cindy Jayne to Everyone:

	I found one reference on carbon footprints of construction of different types of power plants - https://www.carbonbrief.org/solar-wind-nuclear-amazingly-low-carbon-footprints, shows nuclear about the same as solar, and wind is a bit lower.
20:10:48 From Galaxy A10e to Everyone:

	Sizable in the front end-panel 30 year lifespan.
20:13:43 From Galaxy A10e to Everyone:

	But still nuclear is a yuge source of direct warming. Concerns about emissions relate to warming. Over 1..5 C global and its nonstop hell on wheels.
20:14:42 From cbarcus to Everyone:

	GA: yes, we will need to optimize our decarbonization strategy around energy-economics to achieve the highest performance in relation to time.
20:15:57 From Galaxy A10e to Everyone:

	how about underground slowly crushed by earth movements.
20:16:06 From cbarcus to Everyone:

	GA: with climate feedbacks becoming ever more significant, our task gets more difficult…we need a power system that can grow to keep pace with the climate disaster.
20:16:09 From Krestine Reed to Everyone:

	This is an excellent book to learn about what is at Hanford and how it got there. Waste is not energy production; but weapons proliferations; “The Apocalypse Factory: Plutonium and the Making of the Atomic Age”
20:18:18 From Galaxy A10e to Everyone:

	"dirty bombs" already highly radioactive materials ; no fission neccessary.
20:19:21 From cbarcus to Everyone:

	Lots of optimization possible in the nuclear supply chain.
20:20:25 From Galaxy A10e to Everyone:

	Probably a good idea to have a diversity of generating sources, not just nuclear.
20:21:11 From Bill Brigden to Everyone:

	GA, that is the first rational thing you have shared this evening.

	Rare earths will be critical for communications, electric drivetrains, etc.
20:25:56 From cbarcus to Everyone:

	We will bring heavy rare earth mining to the US…but we will need to approach it in an environmentally responsible manner.
20:26:37 From Galaxy A10e to Everyone:

	thirty years. Building solar panels much lower risk industry than preparing nuclear fuels.
20:26:50 From cbarcus to Everyone:

	By optimizing our use of materials, we can minimize the need for mining, reducing environmental impact per capita.
20:27:58 From Galaxy A10e to Everyone:

	Hey I know dump your waste in africa just like the Italian mob.
