Following the collapse of the Soviet Union in 1991, Ukraine, Kazakhstan, and Belarus (the former three Soviet Union countries) unintentionally deployed nuclear weapons within their territory. The former three Soviet Union countries achieved denuclearization by transferring the deployed warheads and the delivery system of the nuclear weapons to Russia for disposal. This report gives our analysis of the success factors for achieving denuclearization by investigating the efforts towards denuclearization of such countries, the relevant frameworks such as the Treaty on the Reduction of Strategic Arms, etc.

The disintegration of central control in the former Soviet Union (FSU) prompted concerns among western countries that weapons scientists and engineers would flee to countries to acquire know-hows of weapons of mass destruction. To reduce this threat, the International Science and Technology Center (ISTC) was established at Moscow aimed at engaging weapons scientists and engineers from the FSU in peaceful use of nuclear technologies. In order to contribute the denuclearization study, it was discussed on contributions and good practice of the ISTC including non-proliferation measures of weapons scientists and engineers, deploying research results.

In order to promote the peaceful use of nuclear energy, it is important not only to ensure safety but also to ensure nuclear non-proliferation and nuclear security. Japan has contributed to the international community through strengthening nuclear non-proliferation and nuclear security capabilities with technical and human resource development. However, in the wake of the accident at the Fukushima Daiichi Nuclear Power Plant in 2011, Japan's nuclear power plants have not restarted or plutonium use has not progressed smoothly. Concerns have been shown. Towards appropriate steps of Japan's nuclear fuel cycle policy, such concerns are examined and future efforts are summarized.

Research on factor analysis for achieving denuclearisation, 3; Denuclearisation at Libya: Process and success factors

Tamai, Hiroshi; Shimizu, Ryo; Tazaki, Makiko; Kimura, Takashi; Nakatani, Takayoshi; Suda, Kazunori

Nihon Kaku Busshitsu Kanri Gakkai Dai-40-Kai Nenji Taikai Puroshidhingusushu, p.89 - 92, 2019/11

Libya's denuclearisation, named "the Libya model", is regarded as one of good practices in cooperation of the international community and measures that have a sense of speed with the countries and institutions involved. Success factors of the denuclearisation are the Libya's relatively low technological progress despite the procurement of extensive nuclear materials and components due to the delay of detecting the nuclear programme, prompt implementation with the close collaboration of countries concerned, and Libya's cooperation facing to the economic sanctions and the regime collapse by the Iraq war. Precious lessons will be learned towards the prevention and the denuclearisation in other countries.

Research on factor analysis for achieving denuclearization, 4; Iraq: Characteristics of Iraq's denuclearization

Tazaki, Makiko; Shimizu, Ryo; Kimura, Takashi; Tamai, Hiroshi; Nakatani, Takayoshi; Suda, Kazunori

Nihon Kaku Busshitsu Kanri Gakkai Dai-40-Kai Nenji Taikai Puroshidhingusushu, p.93 - 96, 2019/11

Iraq, defeated by the Gulf War, had to accept denuclearization under UN Security Council Resolution (UNSCR) 687, but did not immediately and accurately report all its past nuclear activities to the IAEA. IAEA, as an internationally authorized nuclear inspection and verification organization to Iraqi denuclearization by the UNSCR 687, gradually revealed existence and the whole picture of Iraqi clandestine nuclear activities and verified destruction of weapon related facilities and equipment as well as removal of nuclear materials outside Iraq. Analyzing Iraq's characteristics of denuclearization could serve as a good reference for not only preventing nuclear weapons development but also considering their denuclearization in current and future states.

Research on factor analysis for achieving denuclearization, 1; South Africa: Motivations for nuclear weapons development, incentives for denuclearization and characteristics of its denuclearization

Tazaki, Makiko; Kimura, Takashi; Shimizu, Ryo; Tamai, Hiroshi; Nakatani, Takayoshi; Suda, Kazunori

Nihon Kaku Busshitsu Kanri Gakkai Dai-40-Kai Nenji Taikai Puroshidhingusushu, p.81 - 84, 2019/11

South Africa had developed, manufactured, and possessed nuclear weapons, but later dismantled them all together with related facilities and equipment. After joining Treaty on the Non-Proliferation of Nuclear Weapons as a non-nuclear weapon state and concluding a Comprehensive Safeguards Agreement with the Atomic Energy Agency (IAEA), it started peaceful use of nuclear energy. In that sense, South Africa's denuclearization is one of good examples of past denuclearization in the world, although the South Africa's specific policy of apartheid had been deeply connected with its nuclear weapons development and denuclearization. Analysing South Africa's motivations for nuclear weapons development, incentives for denuclearization, and characteristics of its denuclearization could serve as a good reference for not only preventing nuclear weapons development but also considering their denuclearization in current and future states.
