Information released
I confirm that under Section 1 of the FOIA, that we hold the information related to your request.
However we are withholding the information under Section 24 of the FOIA (Safeguarding national security; ICO guidance)
Section 24 sets out the exemption from the right to know where the information requested is required for the purposes of safeguarding national security. It works to protect national security, which includes protection of potential targets. It allows a public authority not to disclose information if it considers releasing the information would make the UK or its citizens more vulnerable to a national security threat.
The following types of information relevant to your request and which engage the exemption set out in Section 24 FOIA include:
• Security of  Nuclear Material and Facilities; 
  • Safety Cases  and Other Safety or Environmental Information; 
  • Contingency  and Emergency Plans & Exercises. 
As this is a qualified exemption, we are required to balance the public interest between disclosure and non-disclosure. We have therefore applied the Public Interest Test, as set out below:
Section 24 FOIA – Safeguarding national security
Factors for  release:  
- Use of the exemption provides no further information to the  public and represents a frustration of ONR’s policy of openness and  transparency. 
 
- Issues related to the nuclear industry are subject to close scrutiny and debate, there is a public interest in information related to nuclear activities and the release of such information. The information may provide reassurance to the public about the safety of nuclear sites. It may also facilitate the accountability and transparency of ONR for decisions taken by them as a regulator and enforcing authority of the nuclear industry.
Factors against release:
- Information that relates to the purposes of  safeguarding national security and which may be of use to terrorists and other hostile actors is exempt from  disclosure. The specific details of these events could provide an adversary  with information that enables them to develop intelligence which may help them  defeat security arrangements. 
 
- Paragraph 13 of Section 24(1) makes it clear that there  need be no evidence that an attack is imminent for this exemption to be  applied. 
 
- Adversaries or hostile actors can be highly motivated and may go to great lengths to gather separate pieces of intelligence to attempt to expose vulnerabilities.
Conclusion
After careful consideration of the factors set out above, ONR has concluded that the information should be withheld. On balance, the interests of national security outweigh the need for openness in terms of the specific information that you have requested. There is a strong public interest in safeguarding national security. Therefore, it is our judgement that publication of the information requested would not be in the public interest.
