We know that #NuclearEnergy is one of the largest sources of zero-emissions power in the ๐, but as any other energy-generation industry, it generates a "waste".
And I got some news for you: It is actually consider a valuable resource, not a waste!
1.#NuclearWaste is an incorrect term for used or spent fuel (Letโs all take note! - myself included)๐
#UsedFuel is made up of metal fuel rods that contains small ceramic pellets of enriched U-235 & it always stay in a solid state.
2. The U.S. ๐บ๐ธ has produced roughly 83,000 metric tons of used fuel since 1950s.
This may sound like a lot, but it actually fit on a single football field at a depth of less than 10 yards.๐
3. The are 76 sites in 34 U.S. states that can store used fuel!
#SpentFuel rods are safely and securely enclosed in steel-lined concrete pools of water or in concrete containers.๐
4. Transportation of spent fuel have occurred around the U.S. without any radiological releases.๐
Used fuel is shipped in special casks that are designed to withstand more than 99% of vehicle accidents, including water immersion, impact, punctures and fires.
Check them out! ๐
5. Spent fuel CAN BE RECYCLED! โป๏ธ
France currently recycle used fuel, since more than 90% of its potential energy still remains in the fuel, even after 5 yr of operation in a reactor.
Recent news about the planned release of treated water from the Fukushima Daiichi NPS into the ocean has sparked concern & debate.
As someone who cares about the environment & public health, letโs talk about the water discharge & the Advanced Liquid Processing System behind it.
But first: Where is this water coming from?
After the March 2011 accident, using water to cool the melted fuel & debris at Fukushima Daiichi NPS has been necessary.
Aside from this, when groundwater & rainwater comes into contact with melted fuel/debris, it becomes polluted.
After becoming contaminated, the water undergoes filtration through the Advanced Liquid Processing System (ALPS), which eliminates a significant portion of the radioactivity before it is put into storage.
Am I the only one that wonders what would happen if I fell into those pools where spent nuclear fuel rods are cooled down?
How would falling in here affect our health? And could we actually survive this?
Letโs evaluate this possibility together.๐ค
So, Iโve just accidentally fallen into a spent fuel pool. But what is it?
While powering a nuclear reactor, the fuel rods become very hot. Weโre talking 1kยฐC (1832ยฐF), so this pool of crystal clear water is meant to cool spent fuel rods after they come out of a nuclear reactor.
Spent fuel rods stay in the SFP typically for 2-5 yrs and are stored under ~20ft of water.
According to @NEI , the U.S. avoided ~471M metric tons of CO2 emissionsย in 2020, equivalent of removing 100 million cars from the road & more than all other clean energy sources combined.
#TuesdayFacts about nuclear power in the U.S.A ๐บ๐ธ
There are 54 commercially operating NPP with 92 nuclear power reactors in 28 U.S. states.
Of the currently operating nuclear power plants, 19 plants have 1 reactor, 32 plants have 2 reactors, and 3 plants have 3 reactors.
The Palo Verde nuclear power plant in Arizona is the LARGEST nuclear plant, and it has 3 powerful reactors with a combined net summer electricity generating capacity of 3,937 MW.
The R.E. Ginna Nuclear Power Plant in New York is the smallest nuclear plant, and it has one reactor with a net summer electricity generating capacity of about 581 MW.
This beauty is the part of the NPP which is used to produce steam to supply the turbine generator units, which in turn generate electricity.
Letโs analyze this system together by using a 4-Loop PWR system by @WECnuclear as an example ๐
Included within the NSSS are the reactor coolant system (primary loop), auxiliary fluid systems & major electrical instrumentation required for the operation & control of the nuclear systems.
The NSSS is also known as the nuclear island.
Can you identify the primary loop?๐
The Reactor Coolant System (RCS) is used to remove energy from the reactor core & transfer that energy either directly or indirectly to the steam turbine, as described by the @NRCgov
Itโs always interesting to read opinions/articles against nuclear power. Not because I agree, but because it helps us, the nuclear advocates, to know how to tackle misinformation.
And I think this article mentions a couple of interesting points that should be discussed๐
1- โNuclear power is not a safe option for the futureโ
Again, relying and discussing the same topics: Chernobyl, TMI and Fukushima.
Did you get this out of @Greenpeace ?
The important question should be: what should we do about the growing need for energy and the demands imposed on us by the climate crisis? Itโs true that renewables cannot fill the gap alone.
