Advanced modeling and testing techniques can be considered as a tool to balance the missing long-term experience with next-generation nuclear plants. However, changes in other operational parameters (higher temperatures, fast neutrons, other coolants) might change also the degree of radiation damage (e.g., thermal creep in addition to radiation creep). Heat Transport and Afterheat Removal for Gas.

The IAEA is supporting a project to collect graphite data and archive it in a. Advanced, future nuclear plants are expected to consist also almost exclusively of metals and alloys, and they are expected to undergo in principle the same types of damage. Technical Report IAEA - TECDOC - 1154, International Atomic Energy Agency, Vienna, Austria. International Atomic Energy Agency, Vienna (Austria). Consequences of such material degradation are discussed for current nuclear plants where a 50-year operation experience exists. As results radiation hardening/embrittlement, enhanced stress corrosion cracking, changes in geometry, degradation of creep properties, and other damage can occur. tematics in the quasideuteron regime', Journal of Nuclear Science and Technol(1995). Appendix 2: the thermal oxidation of graphite,' in Irradiation Damage in Graphite Due to Fast Neutrons in Fission and Fusion Systems, IAEA-TECDOC-1154. a Neutron Ac-tivation Analysis Laboratory, TECDOC-564, IAEA, Vienna, 241 p., 1990. Displacement damage, phase reactions, swelling, irradiation creep, and transmutation are the main physical effects changing mechanical properties and microstructure of materials used in nuclear power plants. IAEA - International Atomic Energy Agency.
The chapter gives an introduction into the main processes occurring in metals and alloys under neutron irradiation.
