Abstract
A new method of correlating radiation damage data is tested using actual measured data taken from the open literature. This method, the activation fluence method, was found to be as accurate as other contemporary models with which it was compared. The new method also has several ad vantages over the other methods.The method employs a new entity, the activation fluence (time-integrated specific activation rate), as the independent variables in a regression model. Temperature at which the irradiation takes place is also a variable.Although the method was tested for a specific type of damage (change in nilductility transition temperature for A302-B steel) it has no inherent restrictions and is limited only by the imagination of the user.
