Conference Article: Design, construction and operation experience of the He-He intermediate heat exchanger

Abstract

The conditions required for the primary helium, which is the cooling medium for the high temperature gas cooled reactor, are prescribed to be 1,000^oC in temperature and 40 kgf/cm² in pressure at the outlet of the reactor, while the conditions required for the secondary helium at the outlet of the intermediate heat exchanger are prescribed to be 925^oC in temperature and 45 kgf/cm² in pressure. This means that relatively high temperatures and high pressure are required for the system. The purpose of the present research and development project is to establish a design method, safety evaluation techniques, and safety-securing measures to be applied to an intermediate heat exchanger and to the overall heat exchanging system, which will satisfy those strict operating conditions as mentioned above. Research and development work on the high temperature heat exchanger has been and is being carried out.
