abstract = {The inherent safety features of modular High Temperature
Reactors (HTRs) make events leading to severe core damage
highly unlikely and constitute the main differentiating
aspects compared to LWRs. Furthermore, while a known and
stable regulatory environment has long been established for
Light Water Reactors (LWRs), different ways of thinking may
help to develop a more appropriate licensing process for
HTR-based power plants.The HTR-L project funded by the
European Commission in the 5th Framework Programme was
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. Several topics were developed during the course of
this project.Due to the characteristics of the HTR design,
it has been necessary to define specific defence-in-depth
requirements which have then been evaluated for
implementation in the safety approach. Safety-related
functions appropriate for the HTR design have also had to be
identified and listed.On one hand, the different possible
solicitations of the fuel particles constituted the starting
point for the identification of the accidental conditions
(by means of the Master Logic Diagrams methodology); these
accidental conditions were classified and the most
appropriate methods to consider ultra low probability severe
accidents were examined.On the other hand, the elements
constituting the source term and, in particular, the
requirements for the confinement of radioactive products and
the conditions required to prevent the need for a
"conventional" containment structure have been discussed.In
the definition of the safety approach, attention has been
paid to the need to maintain the potentially interesting
economic perspectives of HTR reactors. Key issues to be
addressed in the licensing process of the HTRs have also
been identified. An innovative systems, structures and
components classification method has been developed and
rules that will govern equipment qualification proposed. (c)
