 A situação é still complex at the site which is normal if you consider that usually the commissioning project of a nuclear facility is a very difficult project even more for a nuclear accident facility. We have observed a number of activities at the site, a number of tasks and maybe it's a bit premature to give you a final conclusion of the mission on the progress achieved by the TEPCO and the operators of the site but it is obvious also that we have observed very significant progress in relevant areas. I would mention for a sample that they have already concluded the removal of fuel from the SPAM fuel pool of the unit 4. They have already started to work to operate the pumping system of underground water to the sea just to alleviate the situation related with the contaminated water which is accumulated at the site. They have also accomplished a very good clean up of the site which is very relevant from the viewpoint that the radiological conditions have been dramatically enhanced that allows better environmental working conditions for the workers. Maybe we can also mention that they have also installed a very numerous treatment systems which will contribute to enhance the contamination of the water contaminated. At the short term it is obvious that the main challenge they have to affront is this related with the accumulation of water that results in the accumulation of contaminated water. For that issue they have a very comprehensive set of measures to be implemented. They already implemented some of them and they have plans to continue implementing the rest of the issues of the measures to alleviate this situation and this is for the short term but it is obvious that for the long term the most relevant and the most challenging issue will be the removal of the damaged fuel and the nuclear fuel debris. Well the main tool to contribute to the Fukushima project for sure that it is our IAEA safety standards which cover a very broad range of activities or issues related with the Fukushima decommissioning project. Beyond that I think the agency could play an instrumental role in enhancing the interaction between the international community and the licenses dealing with the issue in Fukushima. Just to channelize the international community assistance to give them good practices and assistance on how to accomplish difficult tasks. And also I think it's very important for example conducting this kind of missions where we can provide them with an independent assessment of the situation and the plans they have to continue the decommissioning project. And we are using these missions also to channelize international assistance to Japan and additionally to obtain lessons and experience to be disseminated along the international community.
