Internal operational instructions and guidance
ONR is committed to providing up to date, open and transparent content relating to its current internal instructions and guidance used to carry out its core operational work of inspecting, investigating, permissioning and enforcing.
Keeping ONR's internal instructions and guidance under regular review is a big task. Not all the material presented here is completely up to date but it is all useful. ONR staff understand the context in which they are working and are able to interpret appropriately current material that would benefit from some revision.
The material presented here is essentially the same as it is made available to ONR staff, but with some additional explanation for an external audience.
Not all of ONR’s internal instructions and guidance are open documents. All the fully open material is available on this website.
These documents have been transferred verbatim from HSEs FOI webpages. The HSE Classification Scheme and Retention Schedule outlines the objectives and criteria for organising and managing information. It also explains the policy framework and process for appraising records generally.
ONR's internal operational instructions and guidance are arranged under the following key business activities:
Safety Assessment Principles for Nuclear Facilities
Nuclear site licence conditions
The use of computers in safety-critical applications
The licensing of nuclear
installations
The tolerability of risk from nuclear power stations
