UK HPR1000 Generic Design Assessment - ASTEC Familiarisation Course

ONR requires a contractor to provide a familiarity training course in the ASTEC code.

This should be delivered to relevant ONR staff at our Bootle offices in Liverpool, UK.

The training will be delivered to between 5 and 10 ONR Inspectors, with a range of backgrounds in Fault Studies, Severe Accident Analysis and Chemistry, amongst other disciplines.

The contractor who provides this work should be familiar with the ASTEC code, its development, uses, application, verification and validation.

Ideally the contractor should have expertise in applying this code to nuclear safety applications.

The level of this training is not expected to be at a practitioner level, but at such a level that ONR Inspectors will gain an understanding of relevant topics, such as: Code capability; Code operability - i.e. a demonstration of how the code works; Code limitations; Code verification and validation, including benchmark tests and international experiments; Any examples of where the code has been used directly to support a nuclear power plant safety case or as part of independent confirmatory analysis; Any notable differences or limitations between ASTEC and widely used severe accident codes (e.g.

MAAP and MELCOR); An overview of the technical support available (e.g. user groups, code manuals, international community etc.); Strengths and weaknesses of the code; Any recent code developments or areas identified for future development; Capability of coupling to other codes; Good practice of configuration control of user input and output; Important user assumptions.
