The analyzed structure is a support pad of the RPV (reactor pressure vessel) of a German PWR. There are four support pads equally distributed around the outer surface of the flange of the RPV. Under normal and faulted conditions these support pads serve as a link between the RPV and RPV support construction, which is in the German design a ring ...Author: Konrad Schramm

PWR licensees performed bare metal visual inspections of the RPV head looking for boric acid deposits adjacent to RPV head penetrations. At this time, most of the inspections committed to in response to Bulletin 2001-01 have been completed. In March 2002, in conjunction with the inspections for most NRC Bulletin 2001-01, Davis-Besse

In this investigation, structural dynamic responses of the secondary support structure and the RPV following free drop impact of the core barrel assembly in a PWR were simulated by the explicit finite element code of ANSYS LS-DYNA and structural integrity assessment was carried out based on the design criteria of the ASME Boiler and Pressure ...Author: Yanhui Li, Jin Jiang, Yucheng Wang, Shuang Luo, Rui Ying

Reactor Pressure Vessels (RPV) using Database on RPV Materials to develop the guidelines for prediction of radiation damage to WWER-440 PRVs. The WWER-440 RPV was designed by OKB Gidropress, Russian Federation, the general designer. Prediction of irradiation embrittlement of RPV materials is usually done in

There is, therefore, no reason to believe that the relatively high copper specification of A588 support structure steel will be detrimental to the steels toughness after low temperature/high dose irradiation as expected in the Sizewell B support structure. Keywords:
