The Nuclear Test Ban [fr]

  1. nuclear test ban: France and the CTBT ;
  2. nuclear test ban : monitoring and on-site inspections.

The international nuclear test ban regime, that is under construction, is based in the Comprehensive Nuclear Test Ban Treaty (CTBT) that has not yet entered into force, and on the related verification regime that is deployed through a provisional and voluntary based International Monitoring System.

France and the nuclear test ban


On 29 January 1996, the President of the Republic announced the final stop of the nuclear tests conducted by France for the enforcement of its deterrence program.
Since that day, France constantly reaffirms the urgency and importance to ban all nuclear weapon test explosion or any other nuclear explosion, as entitled in the Comprehensive nuclear Test Ban Treaty (CTBT).

Meeting between the CTBTO Executive Secretary, Mr Lassina Zerbo (left) and the Minster for Europe and Foreign Affairs, Mr. Jean-Yves Le Drian (right), on 11 December 2017.

The first two articles of the CTBT underline that :

1. Each State Party undertakes not to carry out any nuclear weapon test explosion or any other nuclear explosion, and to prohibit and prevent any such nuclear explosion at any place under its jurisdiction or control.
2. Each State Party undertakes, furthermore, to refrain from causing, encouraging, or in any way participating in the carrying out of any nuclear weapon test explosion or any other nuclear explosion.

France is the very first State, along with the United Kingdom, to have signed the Treay in 1996 and to have ratified it in 1998. France is committed to the nuclear test ban, which is one of our first priorities in favor of nuclear disarmament. France calls on all States that have not signed or ratified the Treaty to do so as soon as possible, in order to contribute to international peace and security, as recalled in the United Nations Security Council resolution 2310, adopted on 23 September 2016.

France is actively committed in favor of nuclear disarmament, through being:

  • the very first State to have decided the closing and dismantlement of its facilities used for the production of nuclear fissile material dedicated to nuclear weapons;
  • the only Nuclear Weapon State to have dismantled, in a transparent way, its nuclear test site;
  • the only State to have dismantled its nuclear ground-to-ground / surface- to-surface missiles;
  • the only State to have voluntary reduced of a third the number of its SSBNs (submarine-launched ballistic missiles);
  • a country that has reduced by a third the number of nuclear weapons, missiles and planes related to the air fleet deterrence.

International Day against nuclear tests: 29 August


On 3 December 2009, during its 64th session, the United Nations General Assembly proclaimed that the 29 August will be dedicated to an “international Day against Nuclear Tests “ through the adoption of the 64/35 resolution. This resolution calls on to enhance “public awareness and education about the effects of nuclear weapon test explosions or any other nuclear explosions and the need for their cessation as one of the means of achieving the goal of a nuclear-weapon-free world”. This resolution was initiated by the republic of Kazakhstan, and was supported by numerous countries, in order to commemorate the closure of the Semipalatinsk nuclear test site, on 29 August 1991.

The International day Against Nuclear Tests aims at mobilizing the United Nations Organization, the States signatories, Inter- and Non-Governmental, universities and media towards the improvement of information and public education with the final goal of ensuring nuclear test ban for a safer world.

Since the creation of the International Day against Nuclear Tests, many bilateral and multilateral progress, along with large initiatives from the civil society have contributed to support the nuclear test ban topic.

All has to be done to ensure the Comprehensive Nuclear Test Ban Treaty entry into force and preserve its place into the international framework. On 29 August, the United Nations Secretary General usually delivers a statement on that particular topic. ->].

« The Comprehensive Nuclear-Test-Ban Treaty (CTBT) is a central pillar of international efforts, but despite being widely supported – with 184 signatories and 168 ratifying States – it has not yet entered into force, more than 20 years after its adoption.

On the International Day Against Nuclear Tests, I reiterate my call for all States that have not yet done so, to sign and ratify the Treaty, especially those whose ratification is needed for the Treaty’s entry into force. In a world of rising tensions and divisions, our collective security depends on it.
» — António Guterres, United Nations Secretary-General (29 August 2019)
