SUMMARY

This report presents the findings from activities associated with Work Package G1(b), and is concerned with the definition of a representative range of blast and fire scenarios. A report presenting the review of methods for predicting the rate of release of material has been issued as a separate self-contained G1(c) document.

Under the specific guidance of the Participants' Safety Working Group (SWG), and within the scope and methodology for this Work Package originally proposed by the Project and subsequently agreed by the SWG, a number of rational and consequential activities have been carried out, leading to the definition of a generic set of representative base events and scenarios for fires and explosions. These activities have led to the selection of six scenarios for fire events and a similar number for blast events.

A selection rationale is presented, followed by a description of the approach adopted to establish the scope of this study. The specific methodology and priority rating system adopted is discussed within the context of fire and blast scenarios, and a description of the selected base event scenarios is presented.

The report for Work Packages G1(a) & G2 contains a description of the selected representative module arrangements. These selected cases are used herein to develop a geometry and obstacle database. The contents and layout of the database are described and this database is available on request.

The selected base events described in this document and the geometry and obstacle database, together with the data and information contained in the reports on Work Packages G1(a) & G2 and G1(c), collectively represent foundation and generic data for use in other studies in this Project and in future studies.
