... articulating hull to deal with drag of a long tail
The articulating hull is to assist with tacking (Moving the rudder forward is how they dealt with the drag of a long tow-load).
Why not gybe instead of tacking? I suspect that would risk entanglement with the long tail.
remove the fuel, and separate it enough physically that the reaction 'stops'.
The neutron chain reaction has already stopped. Problem is, so many other isotopes with short half-lives built up over the years of operation, they are now spontaneously decaying, dumping heat. THATS the heat that needs to be removed to prevent melting of zirconium cladding. When it does, redox reaction with water generated the hydrogen gas which exploded.
It is amusing to see the comments here which excuse the problem at the Japanese nuclear plant because the earthquake was really big. You see to many people who don't have an automatic fear of anything nuclear, there remains the problem of the people running it. The technology might be safe but when those in charge aren't doing their jobs then there is basis for distrust.
1. The earthquake was big: It's Japan. You can't not expect a big earthquake. Everything has to be ready for it.
2. The tsunami unexpectedly washed out the generators: see point 1.
3. It was an old plant, the new ones are safer: if this one wasn't safe then why was it running?
The point to me is not that nuclear power is unsafe, but rather that unacceptable risks were taken in this case. Does the same problem exist are other sites in other countries? I have no idea (and I bet the armchair Slashdot crowd doesn't know either), but there is a serious lack of trust right now over how that risk is being evaluated.
None of this excuses the sensationalism in the media or the fools in the US who are buying anti-radiation tonic in preparation, or even the foreigners who are fleeing the entire country of Japan over the threat of 'meltdown'.
PS. What if all six reactors had been working?
Safe nuclear power is incompatible with Private industry - they must cut corners to maximize shareholder returns. That’s why Congress (foolishly) passed the Price-Anderson Act.
The Navy has never experienced a core melt-down (that we know of) despite operating many nuclear-powered subs and aircraft carriers – but they don't have the competitive pressure to maximize profits.
My reading: older, better known reactor designs are safer.
My reading: reactors built by capitalist corporations who face massive financial loss when something goes wrong are safer than reactors built by communist dictatorships to produce plutonium for nuclear weapons.

It's quite illegal in jurisdictions I'm familiar with for a juror in the jury room to say and then follow through by voting on a statement like "I don't care what the law says, I'm not convicting this guy even if he is guilty" while it is perfectly legal for the same juror to keep his trap shut and just vote "not guilty."
You didn't say where these jurisdictions are located, but I don't believe you are correct, at least in the USA - see http://en.wikipedia.org/wiki/Jury_nullification#United_States Also, from http://www.fija.org/docs/JG_If_you_are_called_for_Jury_Duty.pdf "You can't be punished for voting according to your conscience. Judges (and other jurors) often pressure hold-out jurors into abandoning their true feelings and voting with the majority "
You will have many recoverable tape errors.
