Embrittlement correlation research

Office of Nuclear Regulatory Research, U S. Nuclear Regulatory Commission, Washington NRC (1988) Improved Embrittlement Correlations for Reactor Pressure Vessel Steels , p. 569, Washington DC. 

There are three important databases that have been developed by (or for) the NRC PR-EDB, RVID and the so-called Eason database used for research and development of improved embrittlement correlations and trend curves. 

Incorporating these corrections and updates, and adding additional surveillance data from recent capsule testing, the database and NRC embrittlement shift model in NUREG/CR-6551 were updated again in July 2000. Separately, the Electric Power Research Institute (EPRI) and the ASTM E10.02 subcommittee evaluated the database and derived a slightly simpler embrittlement correlation model published as E 900-02 in 2002.

Abstract In this chapter, the development of an understanding of the mechanisms that control reactor pressure vessel (RPV) embrittlement is explored. It is shown how these insights were strongly coupled with developments in microstructural techniques and how research in this field has underpinned the development of dose-damage correlations.
