In response to concerns over the issue of Pressurized Thermal Shock (PTS), Brookhaven National Laboratory (BNL), under the direction of the USNRC, has developed and benchmarked a methodology for calculating pressure vessel (PV) (>1-MeV) damage fluence. The methodology is based on the DOT-3.5 discrete ordinates transport code and has been shown to yield fluence results in good agreement with measurements and results from other calculations. This paper describes the basic methodology employed in BNL PV fluence calculations, and the results of a number of studies performed to assess the impact of various special effects on the calculated (>1-MeV) PV fluence.
