Dear

Environmental Information Regulations Request Reference No: 2012050173

Thank you for your request for information, received on 10 May 2012. I am dealing with it under the terms of the Environmental Information Regulations 2004. Please accept my apology for the delay in providing this response. As previously mentioned, this was due to circumstances beyond ONR's control.

You requested:

Copy of any reports held by HSE ONR on all emergency exercises conducted by the Atomic Weapon Establishment (AWE) in 2010 and 2011

Please find attached copies of five reports-

Some information in these documents is being withheld as it falls under the exceptions in Regulation 13 - Personal Data withheld of the Regs.

Additionally some information within these documents have been redacted under Regulation 12(5) (a) where we believe disclosure would have an adverse effect on international relations, defence, national security or public safety.

An explanation of this decision is given below, as well as the factors considered when deciding where the public interest lies.

Regulation 12(5) (a)

Regulation 12(5) says: For the purposes of paragraph (1) (a), a public authority may refuse to disclose information to the extent that its disclosure would adversely affect:

(a) International relations, defence, national security or public safety.

Factors for disclosure

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

The factors against are that it could have an adverse impact on security or safety and the release of information that could aid the commission of a malicious act and 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.
