Question to the Department for Business, Energy and Industrial Strategy:

To ask the Secretary of State for Business, Energy and Industrial Strategy, what assessment his Department has made of the risk of Stuxnet cyber-attacks on the UK's civil nuclear power programme.

For security purposes, we do not disclose details of potential risks to specific facilities.

The cyber security of existing and proposed nuclear facilities is a priority for the government. The UK civil nuclear sector is subject to a thorough safety and security regulatory regime, including cyber, overseen by the Office for Nuclear Regulation.
