...P. Majumdar; B. Chatterjee; G. Nandan; D. Mukhopadhyay; H. G. Lele In Indian pressurized heavy water reactor (PHWR), loss of coolant accident with simultaneous failure of emergency core cooling system can lead to significant temperature rise in the pressure tube (PT) with the system internal...

... between the first and second bends had already been performed. In this study, the effects of void fraction of the primary coolant coming out from the exit of pressure tubes containing nuclear fuel on the fluid shear stress distribution at the inner surface of the feeder pipe wall have been investigated...

... and structural analyses of the RPV were performed both for the reactor shutdown with postulated upset conditions, as the most severe load case at operation, and for loss of coolant accident (LOCA) conditions. For LOCA transients, a leak size screening of different combinations of cold∕hot leg injection...

...Toshiaki Watanabe; Kazuyuki Hokamoto; Shigeru Itoh In recent years, the usage of cryogenic fluids as coolant are gaining more attention due to their capability to fulfill the requirements of today’s advancing low temperature industrial applications. As a result, the use of a cryogenic pressure...
