Conference Article: Design requirements on HTR main components for process heat application

Abstract

In the field of high temperature reactors for direct process heat, KWU-INTERATOM developed the concept of the heat exchanger (HTR) module. It consists of a number of independent small pebble bed reactor units with a thermal output of 170 MW each. In direct process heat application each of the modules operates in combination either with a steam reformer for hydro gasification of coal and methane reforming, or with an intermediate He/He heat exchanger for steam gasification of coal. Reactor and heat exchanging components are connected by a coaxial duct, helium flow is maintained by an integrated circulator. The primary pressure inclusion is achieved by steel pressure vessels, the technique which is well approved in LWR type reactors. The design requirements presented in this paper are based on the KWU-INTERATOM concept of the heat exchanger (HTR) module, but to a large extent generally typical for high temperature components.
