What is Reactor Pressure Vessel Annealing - Definition

Thermal annealing ( „dry“ method) of reactor pressure vessel is a method by which the pressure vessel (with all reactor internals removed) is heated up to some temperature (usually between 420 – 460 °C) by use of an external heat source (electrical heaters, hot air), held for a given period ( e.g. 100 – 200 hours) and then slowly cooled.
