What are the three levels of waste produced at a nuclear power plant and how is it disposed of?
This information comes from Wikipedia, article on nuclear waste Low level waste (LLW) is generated from hospitals and industry, as well as the nuclear fuel cycle. It comprises paper, rags, tools, clothing, filters, etc., which contain small amounts of mostly short-lived radioactivity. Commonly, LLW is designated as such as a precautionary measure if it originated from any region of an 'Active Area', which frequently includes offices with only a remote possibility of being contaminated with radioactive materials. Such LLW typically exhibits no higher radioactivity than one would expect from the same material disposed of in a non-active area, such as a normal office block. Some high activity LLW requires shielding during handling and transport but most LLW is suitable for shallow land burial. To reduce its volume, it is often compacted or incinerated before disposal. Low level waste is divided into four classes, class A, B, C and GTCC, which means "Greater Than Class C". Intermediate level waste (ILW) contains higher amounts of radioactivity and in some cases requires shielding. ILW includes resins, chemical sludge and metal reactor fuel cladding, as well as contaminated materials from reactor decommissioning. It may be solidified in concrete or bitumen for disposal. As a general rule, short-lived waste (mainly non-fuel materials from reactors) is buried in shallow repositories, while long-lived waste (from fuel and fuel-reprocessing) is deposited in deep underground facilities. U.S. regulations do not define this category of waste; the term is used in Europe and elsewhere. High Level Waste flasks are transported by train in the United Kingdom. Each flask is constructed of 14 in (360 mm) thick solid steel and weighs in excess of 50 tons High level waste (HLW) is produced by nuclear reactors. It contains fission products and transuranic elements generated in the reactor core. It is highly radioactive and often thermally hot. The amount of HLW worldwide is currently increasing by about 12,000 metric tons every year, which is the equivalent to about 100 double-decker busses or a two-story structure built on top of a basketball court. Transuranic waste (TRUW) as defined by U.S. regulations is, without regard to form or origin, waste that is contaminated with alpha-emitting transuranic radionuclides with half-lives greater than 20 years, and concentrations greater than 100 nCi/g (3.7 MBq/kg), excluding High Level Waste. Elements that have an atomic number greater than uranium are called transuranic ("beyond uranium"). Because of their long half-lives, TRUW is disposed more cautiously than either low level or intermediate level waste. In the U.S. it arises mainly from weapons production, and consists of clothing, tools, rags, residues, debris and other items contaminated with small amounts of radioactive elements (mainly plutonium). Under U.S. law, TRUW is further categorized into "contact-handled" (CH) and "remote-handled" (RH) on the basis of radiation dose measured at the surface of the waste container. CH TRUW has a surface dose rate not greater than 200 mrem per hour (2 mSv/h), whereas RH TRUW has a surface dose rate of 200 mrem per hour (2 mSv/h) or greater. CH TRUW does not have the very high radioactivity of high level waste, nor its high heat generation, but RH TRUW can be highly radioactive, with surface dose rates up to 1000000 mrem per hour (10000 mSv/h). The United States currently permanently disposes of TRUW generated from nuclear power plants and military facilities at the Waste Isolation Pilot Plant.

10 facts about the bayeux tapestry?
1] it is currently in france 2] it has latin headings 3] it does not clearly state how harold died 4] it doesnt clearly state which person on the tapestry is harold 5] it doesnt clearly state which person on the tapestry is william 6] Micheal Wood assumed that both men in a scene were harold 7] it is a very very long piece of work 8] they began working on it soon after the battle of hastings 9] noone from the battle of hastings worked on the tapesty so even if you did understand it it may not be truw information 10] Harold's Stepbrother came up with the idea of the tapestry
Asked in Sikhism
When was Sikhism born?
Guru means Enlightener. Sikh means a disciple readily willing to be enligthened from the true guru. In strict sense, the birth of Sikhism is attributed to the founder Guru Nanak. But it is worth noting that Guru Nanak considered Shabad Guru to be his own Guru. So, he was a disciple or Sikh of Shabad Guru/Waheguru/Allah/God the Almighty. Going by this understanding, if any disciple got this message earlier than Guru Nanak, he would also be considered a Sikh. So, if Adam was the first human and he paid heed to Truw Guru's teachings, he would be considered as the First Sikh. So, we can arrive at the conclusion that Gur-Sikh philosophy or Sikkism has been very much in existence, since the time man put his feet on earth.
