Abstract

The inherent safety features of the HTRs make events leading to severe core damage highly unlikely and constitute the main differentiating aspects compared to LWRs. While a known and stable regulatory environment has long been established for Light Water Reactors, a different approach is necessary for the licensing of HTRbased power plants.

Among the R&D projects funded by the European Commission for HTR reactors, the HTR-L project is dedicated to the definition of a common and coherent European safety approach and the identification of the main licensing issues for the licensing framework of the Modular HTRs.

Other specific objectives of this project are :

To develop a methodology to classify the accidental conditions
To define the preliminary requirements for the confinement of radioactive products and to assess the need for a "conventional" containment structure
To establish a SSC (2) classification and to define the rules for equipment qualification
To identify the key issues that need to be addressed in the licensing process of the HTRs
To organize a workshop with the concerned Safety Authorities at the end of the project.

This paper will explain the project objectives and its final expected outcomes.
