The point is surely that the nuclear industry can no longer say well we've engineered these things to be safe to so-and-so tollerances, because the fundamental issue is IF something really powerful hits it, could it lead to a situation where it will leak out real nasties - and if the answer = yes then I think it will be increasingly difficult to justify what will anyway become a more expensive way of generating energy in the wake of the safety measures already implied as coming down the pipeline from this incident?

and a couple of incidents involving Excessive Insertion of the Control Rods resulting in leakage from the valve seat area at our own favourite n.3

Ya. "Excessive Insertion" has happened to me and it's usually pretty painful.

March 25: Workers, who stepped into radiation-contaminated water during Thursday's operation at the Fukushima Dai-ichi nuclear plant, are shielded with tarps before receiving decontamination treatment at a hospital in Fukushima, northeastern Japan.
The tarp shielding was explained last night as normal by a Japanese person on line. It is to afford privacy to the workers from the cameras. It is common practice in Japan

I just wonder whether in the light of this incident, and what has been learnt about seismology, geology, tsunamis, and other natural and man-made hazards in say the past 40 years, the nuclear industry can really assume that it is enough to 100% rule out admittedly rare (this was meant to be a once in a millenium event for instance) yet powerful events that could destabilise or open ANY nuclear plant or storage facility, e.g. in the wake of a meteorite impact (which apart from explosive forces could also create tsunamis ANYWHERE in the oceans...
But, as with most issues relating to nuclear energy, the use of MOX is a source of some controversy. Proponents say that burning MOX in nuclear reactors is a sensible way to dispose of weapons-grade plutonium from Cold War nuclear stockpiles, as the U.S. plans to do with 34 metric tons of surplus plutonium at its planned Mixed Oxide Fuel Fabrication Facility (MFFF) in South Carolina. (Some countries also reprocess spent nuclear power plant fuel to produce MOX.) Critics say that MOX is riskier than standard fuel and that there are better ways to dispose of excess plutonium.
"I think it's a magnificent solution," says David Jones, senior vice president for the back-end business group at Areva, a Paris-based nuclear fuel manufacturer with U.S. headquarters in Bethesda, Md. Areva is half of a partnership that is the prime contractor to the U.S. Department of Energy (DoE) on the $5-billion MFFF project. "You're taking something that was designed to be dangerous, and you're turning it into something that benefits society," Jones says.

It appears Japan is now asking people to evacuate
further away from the reactors.
Too bad its coming about 10 days late, Those people should have been out of there already.
In my opinion the lack of information and contant downplaying of this incident by TEPCO has been criminal. Their actions, or lack of action, will end up costing thousands of lives over the next several years. When the US recommended an 80km evacuation zone you knew it was much worse than they were saying.
As of today, Fukushima radiation was recorded at 24 different stations of the Authority. New detections relate to the station in Stockholm, Sweden as well as stations in the European part of Russia. in extremely dilute form - - For the radiation cloud is already running almost around the entire northern hemisphere. Simulations of the ZAMG show very clearly the spread of the last two weeks. The model has worked generally very satisfactory.
Decontamination (Nicholas A. Groesch, Reuters / March 22, 2011) Sailors aboard the aircraft carrier USS Ronald Reagan conduct scrub down the flight deck to remove potential radiation contamination while operating off the coast of Japan to provide humanitarian assistance.

Stress Corrosion Cracking (SCC)Under the combined effects of stress and certain corrosive environments stainless steels can be subject to this very rapid and severe form of corrosion. The stresses must be tensile and can result from loads applied in service, or stresses set up by the type of assembly e.g. interference fits of pins in holes, or from residual stresses resulting from the method of fabrication such as cold working. The most damaging environment is a solution of chlorides in water such as sea water, particularly at elevated temperatures. As a consequence stainless steels are limited in their application for holding hot waters (above about 50°C) containing even trace amounts of chlorides (more than a few parts per million). This form of corrosion is only applicable to the austenitic group of steels and is related to the nickel content. Grade 316 is not significantly more resistant to SCC than is 304.
[11:34 a.m. ET Friday, 12:34 a.m. Saturday in Tokyo] Three men working near the No. 3 reactor at the Fukushima Daiichi nuclear plant Thursday stepped into water that had 10,000 times the amount of radiation typical for a nuclear plant, a Japanese government official said Friday, but nuclear experts said the burns suffered by the workers may not amount to much more than a sunburn.

I agree something must be happening.
Both my feeds on Kyodo and NHK are not streaming.
I pray everyone is ok over there.
