Influence evaluation of loading conditions during pressurized thermal shock transients based on thermal-hydraulics and structural analyses

Jinya KATSUYAMA, Shumpei UNO, Tadashi WATANABE, Yinsheng LI

Frontiers of Mechanical Engineering 2018, Volume 13, Issue 4,   Pages 563-570 doi: 10.1007/s11465-018-0487-9

Abstract: hydraulic (TH) behavior of coo-lant water is a key factor in the structural integrity assessments on reactorpressure vessels (RPVs) of pressurized water reactors (PWRs) under pressurized thermal shock (PTS) eventsconsiderably influence various parameters, such as the temperature and flow rate of coolant water and inner pressurelead to lower stresses than that under the US rule because an earlier operator action caused lower pressure

In-Vessel Melt Retention of Pressurized Water Reactors: Historical Review and Future Research Needs Review

Weimin Ma, Yidan Yuan, Bal Raj Sehgal

Engineering 2016, Volume 2, Issue 1,   Pages 103-111 doi: 10.1016/J.ENG.2016.01.019

Abstract:

A historical review of in-vessel melt retention (IVR) is given, which is a severe accident mitigationThe idea of IVR actually originated from the back-fitting of the Generation II reactor Loviisa VVER-440The most influential phenomena on the IVR strategy are in-vessel core melt evolution, the heat fluxesimposed on the vessel by the molten core, and the external cooling of the reactor pressure vessel (RPVFor in-vessel melt evolution, past focus has only been placed on the melt pool convection in the lower
