PIT (Public Interest Test) if applicable

Factors for disclosure

Openness and transparency issues related to the nuclear industry are subject to close scrutiny and debate, there is public interest in information related to nuclear activities and the release of such information.

Factors for withholding

Disclosure could have an adverse impact on security or safety. With regard to the release of information that could aid the commission of a malicious act, the public would not expect ONR to release information that would aid such an act.

Conclusion

The balance is clearly in favour of limiting the potential for a malicious act. It is not in the public interest in this instance for a full release of Classified Information that could prejudice national security and help in the commission of a malicious act, so it would favour prudence by not releasing this information.
