“No, no – it wasn’t China – it was India which is producing lots of nuclear plants”. Well its time to get those spreadsheets out again! Data here The average construction time is over 9 years.

Is Natural Background Radiation is Safe?

Before we start I would like to restate that there is no scientific evidence whatsoever that health risks can be measured by total radiation dose alone. It is a complicated subject since it depends on the type of radiation emitted, whether it is internal or external to the body, what the chemical element is – […]

Risk and Radiation

There are many discussions about the risk associated with radiation. I am not going to go into the various arguments about the affects of radiation here but try to explain risk and in particular risk due to exposure to radiation. There are several different definitions of Risk but it can be basically understood as the […]

Power for the People or Profit for the Few?

The changes to the increasing complicated electricity market and the domination of electricity supply by a few big companies brings into question whether the UKs energy policy is being designed to help those big companies of the consumers and tax payers. Ownership or control of energy supply has always been a major source of power […]

Thorium and Proliferation

I will probably write about the Thorium cycle a bit more at some later point. There seems to be a growing number of people who say that we can use Thorium as a nuclear fuel. One of the reasons they state is that you cannot make a bomb from Uranium-233 and therefore the thorium cycle […]

Uranium Reserves

It is often pointed out by the nuclear industry and their supporters that Uranium is quite common. It is present in about 3 parts per million in rock and soil on average and about 3 part per billion in sea water. This fact is totally irrelevant. What is important is how much it costs to […]

Nuclear / Wind Power In China

China did have the most ambitious nuclear programme in the world until putting it on hold after Fukushima. Various targets have been quoted but the one of 30GW seems the most realistic. It was predicted that China would get 30GW of wind capacity by the end of 2010 (http://www.nytimes.com/2009/07/03/business/energy-environment/03renew.html?_r=1). In fact, according to Chinese Renewable […]

Nuclear CO2 Emissions

The UK Government use the British Energy Torness Environmental Impact Statement and the Vattenfall Environmental Impact Statement for their figure of 6gCO2/KWh. However the figures given in these statements are very questionable. Other studies such as the University of Sydney ISA study (http://www.isa.org.usyd.edu.au/publications/documents/ISA_Nuclear_Report.pdf) gives a figure of 65gCO2/KWh which is a bit different.
