A consortium of 5 agencies and 15 countries created the ISS and the currently scheduled construction costs for this projects are in excess of $60 billion. However, the complete cost of the International Space Station along with its contemplated expansions could go even higher than $1 trillion. Nonetheless, by the time it is finished, it will be able to accommodate about one million people.

This is the primary nuclear-fuel reprocessing factory of the UK and extends over 700 acres. The construction costs of this facility are in excess of $15 billion. Reprocessing of a nuclear fuel called Magnox from nuclear power stations in the UK is one of the major activities performed at the facility. It doesn’t come as a surprise that there are detractors of the site, which include an anti-nuclear research publication called New Scientist. The publication claims that the huge pools of sludge and other hazards are dangerous because they may be explosive, but this is denied by Sellafield’s management.
