It looks TEPCO/Government allow the press inside Fukushima I Nuclear Power Plant every three months. The first tour in November last year was only for the reporters and cameramen who belong to the Press Clubs (Japanese and Foreign). The second tour in February allowed the independent media (Iwakami's IWJ and Nico Nico went). The third tour will again allow the independent media, again IWJ and Nico Nico.
What's different this time is, according to the worker who tweets from Fuku-I:
Goshi Hosono, Minister of the Environment and Minister in charge of the nuclear accident, will go with the press on the tour;
They will get off the bus right near the Reactor 4 building;
Hosono and the press representatives may go up the reactor building to see the reinforcement work beneath the Spent Fuel Pool, and go up to the top floors.
The worker who tweets from Fuku-I thinks the reason why Goshi Hosono is coming may be to dispel the rumors circulating around the globe about Reactor 4's building "listing" (leaning, about to collapse, whatever). Bad choice, as Goshi Hosono would be the last person that people would believe. But that aside, the worker doesn't seem particularly worried about Reactor 4 (he never has). From his tweets (here and here):
People in the world are making a fuss about Unit 4, but I think the other reactor buildings would be the same as Unit 4 if an earthquake hits. Other units also have spent fuel, and what's worse there is still fuel inside the reactors. Units 1 and 3 also exploded but they haven't been reinforced. There has been several earthquakes with seismic intensity of 5, but luckily they were OK. I was scared a bit...
It's not that I am optimistic. No one knows what will happen if an earthquake with seismic intensity of 7 hits. But it's not just Unit 4 that is dangerous. They are all the same. They will start removing the spent fuel from Unit 4 in the fall of next year, but it hasn't been decided when the spent fuel in other Units will be removed.
Independent journalist Ryuichi Kino was tweeting he entered the "lottery" to go to the plant....
