Technical assessment guides (TAGs)

The Technical Assessment Guides (TAGs) are intended to give additional guidance to Office of Nuclear Regulation Specialist Inspectors beyond that in the HSE Safety Assessment Principles for Nuclear Facilities (SAPs). Following the completion of the revision of SAPs in 2006 most of the TAGs required updating. However, with the influx of recruits and the events at Fukushima this has been much slower than planned. Also as a result of the Fukushima event, ONR has committed to further revising both its SAPs and TAGs.

The Fukushima Report Recommendation IR-5 work will redefine our previous programme for updating the SAPs.  Details of our new programme and the timescales for updating the SAPs will be placed here once these have been properly developed.

As TAGs become available they will be posted on this website. The existing TAGs were developed to support the 1992 SAPs. These TAGs may continue to be used as appropriate guidance provided by using the identification reference in the SAPs 1992/2006 cross reference table until the revised SAPs and TAGs are produced.
