运行安全评审组成立40年：改进全球核电厂运行安全

OSART missions have contributed to the improvement of nuclear safety worldwide. These safety peer review missions have led to significant improvements in operational safety performance. Recent analysis showed that operators of nuclear facilities act promptly on the findings of OSART missions and that over 95 per cent of the findings are resolved or have achieved satisfactory progress by the time follow-up missions are conducted.

The OSART programme is also constantly evolving to meet the changing needs of the nuclear industry. In recent years, the programme has placed a greater emphasis on areas such as accident management and the interaction between humans, technology and organizations. While human, technological and organizational factors may play a separate and significant role in an operational failure, it is often a combination of these factors that lead to events and accidents.

The programme also emphasizes safety culture, which refers to how an organization’s culture prioritizes and values safety. The OSART programme strives to instil a safety culture that encourages the host organizations to identify and resolve safety issues themselves at an early stage.

With the participation of various stakeholders, including each country's government, host organizations, regulators and industry peers, OSART missions serve as a wide international platform to exchange information and experiences, as well as to provide Member States with good practices and advice to improve safety performance at nuclear power plants. To date, OSART missions have identified 1350 good practices, which are also available to the public on the IAEA’s website. Operating organizations frequently review these good practices and implement those that are applicable to them.

To ensure transparency, the OSART guidelines are available to the public, as are the IAEA Safety Standards on which the service is based.  

“The IAEA’s peer review missions are more crucial now than ever, as they lay the foundation for the significant expansion of nuclear energy required to meet global climate goals,” Director General Grossi said.

“As we mark the 40th anniversary of the first OSART mission, I look forward to our Member States continuing to help us to field these critically important missions across the world,” he emphasized.
