Nuclear power revival

Discussing this precarious issue we study Technical English!

People need to be persuaded in safety of NPPs (Nucler Power Plants) in order to be convinced that all plants, worldwide, are safe.

New conditions

  • Warming of our planet. Finally, governments worried about climate changes and energy security have noticed that nuclear plants emit no carbon dioxide. Moreover, the raw material for their fuel, uranium ore, can be provided by reputable and reliable suppliers.

  • Ricing of oil and gas prices. The recent jump in oil and gas prices, has compeled many governments to reappraise their opinion about nuclear power. In February of this year Italy and Sweden announced plans to start building nuclear plants again. Most of the 40 or so plants now under construction are in Asia (many in China) or Russia. Furthermore, countries in Latin America, the Middle East and Africa are also either building or planning reactors. Turkey, the United Arab Emirates, Indonesia and Belarus are intending to erect their first reactors.

  • Raising to higher level nuclear plants safety. WANO – the World Association of Nuclear Operators has been monitoring safety at nuclear plants for 20 years. IAEA – the International Atomic Energy Agency has developed safety rules, which are voluntary till now. The agency’s experts are invited in to look at nuclear reactors around the world. But governments decide which plants to show, and when.So, last year in November the European Commission proposed making the IAEA’s safety rules obligatory within the European Union. It hopes other regional blocks, such as those of South-East Asia and South America, will follow suit. WANO is considering making their peer review compulsory for each new plant opened by one of its members.

Declining resistence against NPPs

Due to increasing NPPs safety the nuclear industry has had a better safety reputation since Chernobyl. The design and monitoring of many reactors has significantly improved. Even though plenty safety incidents have occured, no big accidents resulting in deaths have happened.

Yet public fears about the safety of nuclear power could still divert its revival. In many countries, majorities oppose building new reactors. People are afraid nuclear accidents, terrorist attacks, the long-term risks of storing radioactive waste and possible divertion of nuclear fuel being to make weapons.

Concern about climate change has softened opposition a little. According to a survey by the European Commission last year, 44% of people in the European Union now broadly support nuclear energy, up from 37% in 2005; and 45% oppose it, down from 55%. In America, about 80% of Americans think that nuclear power will be “an important future source of energy”.

A new reactor being built at Olkiluoto in Finland is one of only two under construction in western Europe. The Finnish government gave the local community a large say in choosing the site of a radioactive-waste depository at Olkiluoto. Switzerland and Canada have taken a similarly democratic approach to nuclear power.

This is a welcome contrast to the secrecy that characterised much of the nuclear industry’s interaction with the public in the past. In some countries that secrecy comes from the military uses of nuclear fission.

Prospects for nuclear power future

The extent to which public opposition can block or reverse the building of new nuclear plants will vary between countries. In any case such plants need “a solid political and social base” in order to survive changes of governments. The simplest way how to get permission for building new reactors is to erect them at existing nuclear sites, e.g. in America, 14 of the 21 applications to start building are for existing sites. Germany faces disputatious energy choices. The fate of its 17 nuclear power plants, which provide almost a quarter of the country’s electricity, is the main point of the discussion. Any renewables are not able to replace electricity generated by these nuclear plants.

Developing-country governments are less likely to care whether the public support of nuclear power. China has 11 nuclear-power reactors already and plans another 20. Companies from the rich world – such as France’s Areva and America’s GE – will find it far easier to build nuclear power plants in the developing countries than at home. Nonetheless, steps must be taken to ensure that less-developed nations run their reactors safely. Last year France created an agency to help newcomers design nuclear laws and set up independent regulators. Unfortunately, there is an irresistible shortage of qualified nuclear engineers, after the three-decade pause in building new plants (see also Are you afraid of nuclear energy?). Actual information about Nuclear Power Plants has just been published on  Statistics on nuclear power. Enjoy reading it.

About renewables position just now

September 6, 2009 · 2 Comments

Compiled by Galina Vitkova

Renewable sources of energy are a hot problem till now. Many specialists, politicians and common peoples discuss advantages and drawbacks of alternative sources of energy. Especially solar, wind and water energy attract debatersˇ attention.

 Since 2004 several international organizations dealing with renewables have been established. The Political Declaration of the International Conference for Renewable Energies in Bonn, Germany in 2004 – initiated the establishment of a global policy network. One year later, in June 2005, the Renewable Energy Policy Network for the 21st Century (REN21) was officially launched in Copenhagen, Denmark.

The strategy of the Network is directed by the Steering Committee of REN21 comprising eminent and prestigious specialists. The Steering Committee members work for various governments, private sector, and civil organisations over all the world. The Secretariat of REN21 is located in Paris, France, and is supported by the IEA.

REN21 strives to encourage the ideas and actions aimed at advance of renewable energy exploitation. Linking participants from the energy, development, and environment communities, REN21 sustains their successes and activities for the rapid expansion of renewable energy worldwide.

 In 2009 REN21 updated the Renewables 2007 Global Status Report, published in March 2008. The updated Report covers the most important changes in renewables worldwide between late 2007 and early 2009. The original 2007 report is available at www.ren21.net.

See below the aggregated data about the state-of-art in this industry

From the report we see that even if the renewable sector driven by policy has been expanding, its share in the worldwide energy production is insignificant. I wonder how this energy will be able to substitute in the near future the energy, which is produced by coal- or oil-fired power plants,

What about you dear colleagues? Does the problem concern you?

iPhone

We study English discussing practical problems

 By P.B.

I have my mobile iPhone more than 4 years and I need a new one. The problem is – which one. I have the Nokia 95 and I like Nokia devices, but I am afraid there are no good Nokia on the market now. I use my mobile phone (like everybody) every day for calling and sending sms but not only for that. It is very important for me – maybe necessary – to receive and send emails with attachments and to have connection to the Internet. On the other side, I don´t need to have applications such as games etc.

 

Many friends recommend me to buy the iPhone. I think it is a very modern phone but I see some problems concerning it. The first one is that if a user wants to backup files, contacts etc., he must use an iTunes application – and it is not very comfortable. The second problem emerges when a user wants to send a business card – in many mobile phones users don´t have any problems with it, but the iPhone doesn´t support it – only between iPhones through Bluetooth when devices are very close to each other. The third problem is that the iPhone doesn´t know the commands copy/paste. The fourth main problem for me is that even though it´s possible to view excel and word documents, you can´t edit them. The fifth problem might be that a slot for a memory card isn´t included.

 

Finally, few lesser problems – the iPhone doesn´t have a radio, on the Internet you aren´t able to view flash and java, there are some problems with MMS and videos (you have to have a special application). Moreover, when you use the Edge for connection to the Internet and somebody call you, the call falls down into the voice box.

 

In my opinion – the iPhone has surprisingly more problems than I expected and I can´t accept this device. Now the Apple has issued a new one – iPhone 3GS – I´m not sure but maybe some problems are solved bythat model.

 

What do YOU think about it?

 

Does anybody have real experience with iPhone and can advise me?
