In accordance with ONR programmes of planned inspections to examine site arrangements under the Ionising Radiations Regulations, IRRs 1999 an ONR specialist radiological protection specialist conducted an inspection on the Devonport Royal Dockyard Ltd (DRDL) licensed site.
The intervention was conducted at the licensed nuclear site and consisted of meetings with site personnel, a plant visit to the radiochemical laboratory and the reactor tooling and training section in the submarine refit complex (SRC)
No System/Structure Based Inspection was carried out.
DRDL’s operations in radiation protection are consistent with several examples of relevant good practice in the following areas:
The improved radiological work control permit package has increased understanding of ALARP controls and the use of red briefs has improved pre planning of work and reduced conflicts
Some areas for improvement were identified as follows:
Some issues have arisen in the population of the Radiological Risk Assessments which are to be addressed by Health Physics Operations Group. The health physics improvement plan in the Radiological Risk Assessment Principles policy clearly states the areas to be worked on in priority order.
From the areas examined I judged the radiological protection arrangements to be adequate, however aspects of conventional health and safety in the radiochemistry laboratory are in need of improvement.
