New Delhi: In a measure to make agenda for upcoming second Nuclear Security Summit, 49 nations are going to hold a preparatory meeting in New Delhi on January 16-17.

The Sherpas or personal representatives of heads of government and officials from 49 countries across the globe are expected to discuss action-oriented measures for improvising nuclear safety ahead of the summit going to be held in Seoul in March.

"A meeting of the Sherpas from 49 nations for the Seoul Nuclear Security Summit will be held in New Delhi on 16-17 January 2012," an External Affairs Ministry statement said here.

Foreign Secretary Ranjan Mathai, India's Sherpa, will open the meeting on Monday.

The main thrust of the meeting will be to discuss the effective measures for nuclear security and the management of radiological materials.

The officials aim at preparing a blueprint for an interface between nuclear security and safety by including eight vital issues so that strong and effective standards can be finalized before the meet.

Notably, the meeting will be crucial for restoring the lost confidence of the international community in nuclear power after the tragic Fukushima disaster in Japan that happened last year.
