Spent nuclear fuel is radioactive, and it generates heat for a considerable period following removal from the reactor core. Storage in a pool of water keeps it cool.
No, chlorinated pool water is not more dense than fresh water. Both chlorinated pool water and fresh water have a density of approximately 1 g/cm3 at standard temperature and pressure.
Shocking a pool with products like chlorine can actually lower the pH and alkalinity levels of the pool water temporarily. It is recommended to test the water and adjust the alkalinity levels if necessary after shocking the pool to maintain proper water balance.
Chlorine itself is not bad for the pool, as it helps sanitize the water and keep it safe for swimming. However, high levels of old or "spent" chlorine can create chloramines, which can lead to eye and skin irritation. It is important to regularly test and maintain the chlorine levels in your pool to ensure a safe and enjoyable swimming environment.
Chlorine can oxidize certain forms of chromium in pool water, particularly chromium ions. However, the effectiveness of chlorine in removing chromium from pool water depends on various factors such as the form of chromium present and the concentration of chlorine. It is recommended to consult with a pool water professional for specific guidance on treating chromium in pool water.
Chlorine stored in a garage cannot change into chloroform. Chloroform is a different chemical compound. However, improper handling and mixing of pool chemicals can create harmful byproducts like chloroform, which can be a health hazard if exposed to for prolonged periods. It is essential to follow safety guidelines provided by the manufacturer when handling pool chemicals.
Spend fuel rods (in the form of fuel bundles) are lifted out of a reactor (which is shut down, of course) and moved over to a holding area. A crane is a good choice for this job. With everything set up, the bundle is hoisted, and swung over a holding area (a holding pool filled with water), and then lowered in. There will be a "rack" of sorts in the pool to support the fuel bundle. Other bundles of spent fuel will be added as they are pulled from the reactor.
Spent fuel from a reactor is stored under water in a concrete and steel pool to cool and shield it for at least ten years after it is removed from the reactor. After this time, it has decayed sufficiently and heat production is low enough such that it can be removed from the water and decay in the air. It is still shielded to prevent exposing people near it and it is kept under lock and key at the power plant or storage facility to maintain control.
In most cases you would be just fine, the water absorbs most of the radiation so there isn't much on the surface of the pool. Many plants routinely have divers go into the pool to repair lights and various other components. The biggest concern would be contamination, after getting out of the water you'd likely have to spend awhile with the Radiation Technicians while they decontaminate you. So long as you don't ingest mass quantities of the water or actively dive toward the fuel assemblies, you should emerge unscathed.
I heard the answer myself on TV today: about 1300 t (the pool is 11 m deep, 29 m long, and 12 wide, but because it is filled with spent rods less water is needed than if it were empty)
In an organic cooled power reactor, spent fuel is typically transferred to a spent fuel pool for initial cooling and radiation shielding after it is removed from the reactor. After sufficient cooling, the spent fuel may be moved to dry cask storage or other long-term storage solutions designed to safely contain radioactive materials. Ultimately, the management of spent fuel is subject to regulatory frameworks and may involve reprocessing or disposal in geological repositories.
Atmosphere is not a storage pool. It is not a physical reservoir where water is stored, but rather the layer of gases surrounding the Earth.
Usually gas or heatpump
Low and intermediate level waste from Koeberg is transported by road in steel and concrete containers to a remote disposal site at Vaalputs, 600km away in the Kalahari Desert. However high level waste (the spent fuel) is stored on site. The spent Uranium 235 rods are currently stored on high-density racks submerged in a reactor pool. The rods take 100 000 years to decay, and between 30 and 50 years to cool down to reach the boiling point of water
burying them in deep caverns, removing lighter nuclei and reusing them
If you have a deck level pool or spa (water level with the top of the pool, that usually overflows into a grating around the pool) when people get into the pool their body displaces water, this water is stored in the Balance tank until the people get out and the water is pumped out of the balance tank and back into the pool. A skimmer pool that has a lower water level than the top of the pool does not need a balance tank as the displacement is handled by the water level rising. Deck level pools and spas are considered more aesthetically pleasing.
In the US it is stored on the power plant sites because no central repository has been authorised so far. In some countries like the UK and France, it is brought together on one site - Sellafield in the UK. But there is still no final long term store available. There are different was to store the waste, at the plants where it was produced. Initial storage is usually in what is called a spent fuel pool, which is literally a large pool of water. This is done because the fuel is very hot and radioactive for a period while the isotopes with short half lives decay a bit. The period is usually more than five years. After the time at the spent fuel pool, it may be removed to what are called dry casks. These are made of thick concrete and allow the materials to decay longer without a need for a constant supply of water. Research is still being done in how to deal with nuclear waste.
