Austrian scientist prepares for entry into force of UN nuclear ban treaty

Scientists are being trained by a UN-backed organization in methods to monitor whether or not a nuclear explosion has taken place.

The workshops have been organized by a commission known as the CTBTO which is preparing for the entry into force of a UN treaty that bans nuclear explosions anywhere in the world.

The historic treaty on banning nuclear weapons was adopted at UN Headquarters on July 7.

UN nuclear test ban needs to be enforced, says Uruguay’s vice minister

A ban on all nuclear testing would send a “clear message” that the international community is determined to achieve a nuclear-free world.

That’s what José Luis Cancela, Uruguay’s vice minister of foreign affairs, said during the Science and Technology Conference 2017 in Vienna, Austria.

The Comprehensive Nuclear-Test-Ban Treaty, which prohibits all nuclear explosions, was adopted by the UN General Assembly 20 years ago but it has yet to come into force.

North Korea urged to halt nuclear tests

The United Nations continues to monitor developments in the Democratic People’s Republic of Korea (DPRK) following the country’s testing of a nuclear bomb.

Dr Lassina Zerbo is at the helm of the Vienna-based CTBTO, the UN body which monitors nuclear explosions worldwide in line with the Comprehensive Nuclear-Test-Ban Treaty.

CTBTO monitoring stations had picked up “unusual” seismic activity in the DPRK on Wednesday morning, in the area of the country’s nuclear test site.

Cristina Silveiro spoke with Dr Zerbo to find out more.

Iran deal stepping stone to universal ban on nuclear tests

A landmark deal to strictly curb Iran’s nuclear programme can be built upon to ensure universal ratification of a global treaty to ban all nuclear tests.

That’s according to Lassina Zerbo, Executive Secretary of the Comprehensive Nuclear-Test Ban Treaty Organization, CTBTO.

Iran signed an international accord in July to significantly limit the country’s nuclear ability for more than a decade.

Mr Zerbo said the nearly 20-year old test ban treaty is being held “hostage” by eight specific nations with nuclear technology that must join it before it can take effect.
