The compact design of mechanical cooling towers necessitates that the plumes are issued into the cross-wind in close proximity.
The pools have mechanical cooling and filtration systems that circulate water past the spent fuel rods, which continue to generate heat years after being removed from the reactor.
With the majority of workplace settings in developing countries being heavily influenced by outdoor temperatures (in the absence of mechanical cooling), it can be expected that both indoor and outdoor workers may experience heat stress.
With most workplace settings in developing countries being heavily influenced by outdoor temperatures (in the absence of mechanical cooling), it can be expected that both indoor and outdoor work may contribute to greater than recommended levels of heat exposure.
Despite the inherent risks in some buildings that have no mechanical cooling, typically the risks of overheating are mild to moderate based on design assessments.
The Eastgate Centre, a shopping centre and office block in Harare, Zimbabwe, has a mechanical cooling system made up of vents and flues that help hot air out of the structure.
The report shows that data centres can operate without mechanical cooling across much of Europe and North America.
The dry casks require no mechanical cooling because the fuel placed inside them has cooled enough so that the simple circulation of air outside of the steel box will keep the temperature well below the fuel's melting point.
The Seed Vault, with its combination of natural and mechanical cooling systems and safe, remote location, is designed to provide a service that no other genebank can offer, and which will function effectively centuries into the future.
In fact, it demonstrates that in many countries, data centres can be operated without any mechanical cooling whatsoever.
