Conference Article: HTR-E Project: High Temperature Components and Systems

E. Beruil, FRAMATOME-ANP, France and R. Exner, Borsig Energy GmbH, Germany

Abstract

The HTR-E European project (four years project) is proposed for the 5th Framework Programme and concerns the technical developments needed for the innovative components of a modern HTR with a direct cycle. These components have been selected with reference to the present projects (GT-MHR, PBMR) :

the helium turbine, the recuperator heat exchanger, the electro-magnetic bearings and the helium rotating seal.
the tribology. Sliding innovative components in helium environment are particularly concerned.
the helium purification system. Recommendations on impurities contents have to be provided in accordance with the materials proposed for the innovative components.

The main outcomes expected from the HTR-E project are the design recommendations and identification of further R&D needs for these components. This will be based :

on experience feedback from European past helium test loops and reactors
on design studies, thermal-hydraulic and structural analyses
and on experimental tests
