Fukushima notes

With the news last night that a couple of workers from the reactor are in hospital with radiation burns, it’s clear that the current operations remain very dangerous.   Even modest advances are being greeted as big progress:  for example, yesterday’s news that lights have been turned on in a couple of control rooms. 

Time magazine has an interesting entry about the ongoing issues at the plant.  As the New York Times noted, one concern is the use of seawater as a temporary coolant:

As  seawater evaporates, salt scaling could insulate the reactor fuel and impede heat transfer and thus cooling. In a worst case, as the rods heat up, their zirconium cladding could rupture, and  gaseous radioactive iodine inside could leak out; the uranium core itself could even melt. This, of course, would release event more radioactive material.

The BBC has a sort of retrospective of the last couple of weeks which is well worth reading too.

Meanwhile, I have stumbled across another example (apart from Andrew Bolt) of a climate change skeptic who has been in an unseemly rush to declare that there has barely been a major problem at all.

The Register, as I recall, has long been keen to run anti climate change articles.    If you have a look at the list of article titles by one Lewis Page,  who himself appears to be quite the CO2 skeptic, it makes for mildly comic reading:

14 March:   Fukushima is a triumph for nuke power: Build more reactors now!

First lines: 

Japan's nuclear powerplants have performed magnificently in the face of a disaster hugely greater than they were designed to withstand, remaining entirely safe throughout and sustaining only minor damage. The unfolding Fukushima story has enormously strengthened the case for advanced nations – including Japan – to build more nuclear powerplants, in the knowledge that no imaginable disaster can result in serious problems.

15 March: Fukushima update: No chance cooling fuel can breach vessels

16 March: Situation worsens - still no cause for alarm

17 March: Fukushima on Thursday: Prospects starting to look good

18 March: Fukushima one week on: Situation 'stable', says IAEA

21 March: Fukushima: Situation improving all the time. Food, water samples OK, Hyper Rescue Super Pump in action

22 March: Fukushima's toxic legacy: Ignorance and fear. Hysteria rages unchecked as minor incident winds down

23 March: Radioactive Tokyo tapwater HARMS BABIES ... if drunk for a year. Iodine isotope will all be gone in weeks, though

The glass is always more than half full for Mr Page.
