About 30 countries participating in the April 2010 Nuclear Security Summit made over 60 specific national commitments to bolster global security. These national commitments include pledges consistent with the declarations in the NSS communique and work plan. They can be categorized as follows; international conventions, removing and securing HEU, reactor conversions or shut down, cooperation with the IAEA, center of excellence and preventing nuclear smuggling. It is believed that the implementation of these national commitments is a crucial for the success of 2012 NSS. It is known that implementation report of each participating country will be submitted on a voluntary basis before the 2012 NSS. It is not easy for the developing countries to overcome technical barrier to implement the commitment. The goals for securing world cannot be achieved by several countries that have advanced systems. Technical barriers between developed and underdeveloped countries should be lifted. In this session, we can discuss on how to encourage countries to accomplish their commitment and on how to reduce the technical barrier. Management of the implementation report (responsibility to collect and evaluate the report; former host country, current host country or the third party?) can be an interesting talking point.
