Eskom and the Department of Energy have recently cranked up efforts to move forward with the plans for more nuclear energy for South Africa. In the Environmental Impact Assessment being prepared by GIBB consultants, the background to this includes a graph of the predicted peak electricity demand. Here is the graph they use, on page 2 of the latest combined main report, released in September 2015: Continue reading
As South Africa contemplates building nuclear power stations along the coast, consultants from GIBB have been given the job of assessing the potential impacts of doing this. This includes looking at the risks.
One obvious risk is that of an earthquake damaging the nuclear reactor, as happened in 2011 in Fukushima. To assess this risk, GIBB produced a specialist report in 2011 (i.e. done before Fukushima) titled “Appendix E4: Seismic Risk Assessment”. Continue reading
Will South Africa be able to raise the money to purchase a nuclear power reactor? Probably not. The Treasury recently admitted that it has done no costing or affordability study for nuclear power, and the 2015 budget made it clear that no money has been allocated for the next three years.
And every year, prospects get bleaker for the nuclear industry…
In addition, the falling value of the Rand, and the constantly increasing dollar cost of nuclear plants make it less affordable for South Africa with each year that passes. But just because the train will never reach its destination, that doesn’t mean you can’t get aboard and enjoy the gravy! Continue reading
I am in Upsala, Sweden, as a guest of the Swedish Society for Nature Conservation (SSNC). It has nearly 200 000 paying members, a full-time staff of about 90, and produces a magazine every two months for its members. It has been an interesting first day in Stockholm, with a lot to take in.
Sweden generates about half of its electricity from nuclear power, and, like all countries with nuclear power, the country is wrestling with the issue of what to do with the spent nuclear fuel, or in technical terms, the high level waste. This remains dangerously radioactive for thousands of years, and disposing of it safely is a huge engineering challenge. Continue reading
During our recent trip to Fukushima, we carried two geiger counters with us, one inside the bus, and one taped to the outside of the window, facing inwards.
These geiger counters measure gamma radiation, and give a readout in micro Sieverts per hour, or μSv/h. Most people in the world are not familiar with these units, but, of course, here in Japan there is a high level of familiarity and interest in radiation levels. For example, on the right is a map stuck on the lockers in an office I went to. Continue reading
I am sitting in a hotel in Tokyo, after attending the Global Conference for a Nuclear Power Free World this past weekend. The sessions were video recorded, and was streamed in real time. Over 100 000 people watched the streaming. See http://npfree.jp/english/
Before the conference we were taken on a two day tour of Fukushima city and some areas nearby, and listened to local people talk about the experience, Continue reading
‘Safe’ is an interesting word, in that it means different things to different people. To the public, ‘safe’ often means ‘cannot fail’, whereas to an engineer, it only means that something is within the accepted safety standards. Continue reading
