Tepco is the company responsible.
It would help in getting answers if others would copy, adding any other questions or remarks that occur.
1 What is the composition of the steam coming out of Reactor2?
2 If it contains radiation, why has that steam not been captured and treated already?
3 Are there plans to capture this steam?
4 When R1,3 and 4 are covered as per Tepco's plans, will the contained air be extracted and filtered?
5 Why will it take so long to pump out the basement of R2? What is the block to putting more pumps in place?
6 What plans are in place to minimise air and groundwater pollution in the event of the corium escaping containment and coming into contact with groundwater?
7 Is it possible to remove the spent fuel pools from the reactor buildings in order to facilitate control?
8 What would be the consequences of abandoning attempts to achieve cold shutdown and simply burying the reactors?
