Fukushima Nuclear Accident – Why I stay in Tokyo

Why I stay in Tokyo

僕が東京にとどまる理由

[This commentary contains footnotes and links that allow you to verify what I am saying.]

Thousands have left Tokyo recently in a panic about the perceived radiation threat. If you ask any one of them to precisely articulate what the threat consists of, they will be unable to do so. This is because they actually don’t know, and because in fact there is no threat justifying departure, at least not from radioactivity (*).They flee because they have somehow heard that there is a threat – from the media, their embassies, their relatives overseas, friends, etc. These sources of information, too, have never supplied a credible explanation for their advisories.

But they have managed to create a mass panic, leading to thousands of people wasting their money on expensive air fares, disrupting their professional lives, their children’s education, and the many other productive activities they were going about. In some cases, foreign executives have abandoned their post in Tokyo, guaranteeing a total loss of respect among those who have stayed behind. Some service providers catering to the foreign community have lost almost their entire income over night. Other providers reversely will lose long-term clientele because they have fled, leaving their remaining customers and clients forced to find new providers. Domestic helpers (especially from the Philippines) have suddenly lost their livelihoods because their “employers” think it’s alright to run away without paying their helpers another penny. Another result of all the hysteria is that attention has been diverted away from the real disaster: the damage done in north-eastern Japan where thousands have died, and many tens of thousands live in dreadful conditions right now, waiting for help.

Contrast this with the fact that radioactivity levels in Tokyo are entirely safe and have been since the beginning of the Fukushima incident (*1a, and *1b for continuous updates). Modern instruments to measure radioactivity are extremely sensitive and precise, and report even the smallest deviations with impressive reliability. Nowhere in the Tokyo area have there been any measurements that would imply any sort ofhealth risk. There certainly have been increases in radioactivity but they are tiny and simply irrelevant to anyone’s health. There is also no fear that there could be some kind of cover-up.

Instruments to measure radioactivity are available at many different research institutions that are not controlled by the Japanese government. The J-gov does also not control the media. They simply have no laws and no means to do so.

[Editor's Note: For a contrast, the background level in London is 0.035 to 0.05 µSv per hour, see the pie chart for an average breakdown by source. Also, see this great chart.]

Fukushima nuclear accident: Saturday 19 March summary

Last Saturday the the crisis level at the Fukushima Daiichi nuclear power station was rapidly on the rise. Hydrogen explosions, cracks in the wetwell torus and fires in a shutdown unit’s building — it seemed the sequence of new problems would never end. A week later, the situation remains troubling, but, over the last few days, it has not got any worse. Indeed, one could make a reasonable argument that it’s actually got better.

Yes, the IAEA has now formally listed the overall accident at an INES level 5 (see here for a description of the scales), up from the original estimate of 4. This is right and proper — but it doesn’t mean the situation has escalated further, as some have inferred. Here is a summary of the main site activities for today, followed by the latest JAIF and FEPC reports. You also might be interested in the following site map:

Another large cohort of 100 Tokyo fire fighters joined the spraying operation to cool down the reactors and keep the water in the spent fuel ponds. The ‘Hyper Rescue’ team have set up a special vehicle for firing a water cannon from 22 m high (in combination with a super pump truck), and today have been targeting the SNF pond in unit 3. About 60 tons of sea water successfully penetrated the building in the vicinity of the pool, at a flow rate of 3,000 litres per minute. Spraying with standard unmanned vehicles was also undertaken for 7 hours into other parts of the the unit 3 building (delivering more than 1,200 tons), to keep the general containment area cool. The temperature around the fuel rods is now reported by TEPCO (via NHK news) to be below 100C.

Conditions in unit 3 are stabilising but will need attention for many days to come. Promisingly, TEPCO has now connected AC cables to the unit 1 and 2 reactor buildings, with hopes that powered systems can be restored to these building by as early as tomorrow (including, it is hoped, the AC core cooling systems), once various safety and equipment condition checks are made.

Holes were made in the secondary containment buildings of Units 5 and 6 as a precautionary measure, to vent any hydrogen that might accumulate and so prevent explosions in these otherwise undamaged structures.  The residual heat removal system for these units has now been brought back on line and these pools maintain a tolerable steady temperature of 60C. More here. These buildings were operating on a single emergency diesel generator, but now have a second electricity supply via the external AC power cable.
