...Chu Qibao; Wang Qing; Fang Yonggang; Tan Wei To ensure the structure integrity of the reactor pressure vessel (RPV) in pressure water reactor plants, the main challenge is the embrittlement of beltline materials. However, the stress at inlet or outlet nozzles of the RPV which are reinforced...

... the structural integrity of reactor pressure vessel (RPV) within a prescribed hour. Essentially, the most dangerous thermal–mechanical loads can be specified as the combination of critical heat flux (CHF) and internal pressure. The CHF is the coolability limits of RPV submerged in water (∼150 °C) and heated...

...Dieter Beukelmann; Wenfeng Guo; Wieland Holzer; Robert Kauer; Wolfgang Münch; Christoph Reichel; Peter Schöner One of the critical issues for reactor pressure vessel (RPV) structural integrity is related to the pressurized thermal shock (PTS) event. Therefore, within the framework of safety...

...Dieter Siegele; Igor Varfolomeyev; Gerhard Nagel The brittle failure assessment for the reactor pressure vessel (RPV) of a 1300 MW pressurized water reactor was revised according to the state of the art. The RPV steel is 22 NiMoCr 37 (A 508 Cl. 2). The expected neutron fluence at the end of license...
