Danger to nuclear power plants of extreme weather conditions

Nuclear plants must resist extreme weather http://www.swissinfo.ch/eng/swiss_news/Nuclear_plants_must_resist_extreme_weather.html?cid=33059156   Jul 6, 2012  Switzerland’s nuclear power plants have until the end of 2013 to demonstrate to the country’s safety watchdog that they are equipped to withstand weather conditions such as tornados, high winds, heavy snowfall and extreme temperatures.

The Swiss Federal Nuclear Safety Inspectorate (ENSI) said on Friday it
had written to the operators of the country’s five nuclear power
facilities to outline the conditions for meeting the requirements.

The onus on operators to demonstrate that their plants can resist
extreme weather was one of the outstanding issues highlighted by the
European Union stress tests carried out in the wake of the Fukushima
nuclear disaster last year.

Swiss nuclear power plants were able to demonstrate “high safety
margins and strong robustness”. The Swiss facilities were also praised
for having seven levels of security of energy supply.

However, events such as drought, freezing rain, ice, forest fires and
heavy rainfall at nuclear sites must still be considered, ENSI said in
a statement on its website.

Operators have until the end of this year to present a timetable for
the weather safety demonstrations.
