Technical assessment guides (TAGs)

The Technical Assessment Guides (TAGs) are intended to give additional guidance to NII Assessors beyond that in the HSE Safety Assessment Principles for Nuclear Facilities (SAPs).  Following the completion of the revision of SAPs in 2006 (SAPs06), consideration was given to revising the supporting TAGs.  Due to resource constraints the revision process has been delayed and will extend over a longer period than originally envisaged.

The revision of TAGs has been prioritised and is made up of two projects:

1. those TAGs deemed necessary for the Generic Design Assessment (GDA) process for new civil reactor designs and those TAGs needed to fill gaps due to the additional areas covered in SAPs06 - completion dates are shown in the accompanying table.
2. the remainder which have not yet been programmed

(Already “completed” TAGs need to be checked against various requirements that have arisen since their completion, hence are included in the table.)

The details of the TAGs in Project 1 and Project 2 may change as resources change or further gaps in the TAGs suite are identified.  Revised programmes will be issued on this website as necessary.

As revised TAGs become available as “Working Drafts” they will be posted on this website. Comments on the programme and the Working Drafts can be made through ndenquiries@hse.gsi.gov.uk

NB.  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 TAGs are produced.
