Position Statement

The Shielding Forum is the independent UK authority for shielding principles, methodologies and core skill requirements for the nuclear industry, and is a recognised Centre of Excellence.


The Shielding Forum is accountable to the UK industry, contractors and regulators which its membership represents. Objectives include

   to promote the identification, review and dissemination of shielding good practice and expertise/experience

   to promote innovation to maximise the efficiency and effectiveness of shielding in its contribution to plant and site safety

   to actively seek to co-ordinate with other relevant specialist network groups, key industry groups and national/international agencies

   Maintain and development of key skills


   To advise - to be visible and accessible for authoritative advice on generic shielding issues in the UK

   To deliver - where appropriate, to develop and deliver Forum ‘products’ – handbooks, training, validation reports, conference papers etc.


Statement of Benefits/Added Value to Business: 

·        Achievement of consensus on good practice for relevant radiation shielding issues. This leads to improved efficiency in the application of shielding methods and procedures resulting in cost effective shielding solutions both in terms of assessment time and implementation costs.

·        The promotion of innovation encourages a continuously improving approach to radiation shielding. By encouraging novel application of shielding technology, in terms of supporting IT, assessment processes and shielding designs leads to more cost effective shielding.

·        Co-ordinating with other relevant groups allows the shielding community to:

·         learn from the common good practice associated with operating expert groups

·        learn of , assess and disseminate relevant developments from other groups / agencies to enable a timely and UK consistent approach to such information

·        The support of the Site Licensees ‘Intelligent Customer’ role is a new objective brought about by the changing industry structure. It is expected that as expertise diffuses away from the Site Licensees there will be a growing need to protect the core skills required by those left behind. As this is an industry wide issue there are likely to be benefits of scale from taking a collective approach.




The forum meets on a biannual basis in May and November. The May meeting is normally held at the ANSWERS seminar on the South Coast, whilst the November meeting occurs at other member sites, normally in Northern England.


Annual Costs:

Standard T&S for individuals – cost met by member organisations

Cost of meeting rooms, lunch etc provided by host organisation.


Resource Requirements: 

No extra resources above and beyond time and expenses for TSF members are currently required.  Production of the proposed Shielding Handbook may require some central funding to support contractor effort.





Annual Report – Summary 


Purpose of Group - Outline


TSF has been debating its role in the new industry environment which resulted in the revised position statement shown above. This represents a significant change in scope from a previous a position of being a networking hub for shielding experts. The move to a more authoritative voice in UK radiation shielding was agreed by members to be appropriate and of particular relevance in today’s industry structure. That structure which gives a greater role to contractors is reflected in the present membership of the forum.

The purpose of the forum is therefore to pursue this wider role through the objectives given above. In particular the forum’s present priorities are to :

  • Help define a minimum standard for radiation shielding skills required by practitioners in industry.
  • Assist with the training of new shielding assessors through the running of relevant workshops.
  • Continue support to the NTEC MSc to educate new graduates in radiation shielding.

Major Current Issues


·        To build up links with other specialist network groups. We already have strong links with the WPC (Working Party in Criticality) and have recently strengthened links with the IRPCG (hence this proforma). We believe such groups have many common interests and issues which can benefit from wider interactions.

·        Funding of activities. Although funding to date has been provided by participating organisations, this has been at a low level, being restricted to meeting attendance and contributions to a few document reviews. If the above objectives are to be pursued effectively external funding may be required.

·        Attracting new blood into the area. The discipline is a physics based area which is competing for a small pool of graduates. Support to NTEC and other relevant initiatives will continue to be pursued.


Summary of some previous activities

  • Organisation of  ALARP workshop for shielding practitioners, with presentations from Industry and Regulators
  • Introduction of deterministic shielding code to the UK as a complementary tool to existing Monte Carlo methods. Involved organisation of training sessions and sharing of user experiences
  • Organisation of workshop and collating of comments on recent ICRP draft publications
  • Commenting on and discussion of NII Shielding Technical Assessment Guide (TAG)
  • Identification of improved data requirements for existing shielding codes (ANS build-up data)
  • Workshop on shielding accreditation
  • Position statements on various key issues e.g. validation of shielding codes.
  • Hand calculation workshops

Major Future Issues


·        The need to maintain a viable skills base to support the UK’s future requirements.

·        Consideration of a wider accreditation scheme for all shielding practitioners (covering basic skills and application specific skills)
