Possible design of PBR for passive decay heat removal
Journal of Nuclear Science and Technology, 2015Conditions for design parameters of above-ground and underground, prismatic high-temperature gas-cooled reactor (HTGR)s for passive decay heat removal based on fundamental heat transfer mechanisms were obtained in the previous works. In the present study, analogous conditions were obtained for pebble bed reactors by performing the same procedure using ...

Decay heat removal options in nuclear rocket engines
29th Joint Propulsion Conference and Exhibit, 1993Nuclear rocket engines which are to be restarted require cooling of the reactor core after each run. Cooling will be required after each shutdown for times from half a day to five days depending on the length of the run. Calculation of the decay heat from fission products and transuranic elements are presented for each in a series of runs typical of a ...

Introduction of IDINHX, A New Heat Exchanger for Passive Decay Heat Removal
Nuclear Technology, 2008Decay heat removal in a nuclear plant is very important, and the performance of a decay heat removal system in a plant is a critical factor for the plant safety. In designing the decay heat removal system, a passive-type system is usually more difficult than an active-type system, and there can be additional restrictions in designing plant systems for ...

Investigations of accelerator reliability and decay heat removal for accelerator-driven system
Annals of Nuclear Energy, 2019To realize the feasible accelerator-driven system (ADS) concept, the investigations for the reliable accelerator and conceptual plant design considering safety issues were performed. As the reliable accelerator concept, the double-accelerator concept was

Control of decay heat removal through alternate system in PFBR
Nuclear Engineering and Design, 2013Abstract In the Prototype Fast Breeder Reactor (PFBR) decay heat is removed directly from the reactor core through Safety Grade Decay Heat Removal (SGDHR) circuit. Operation Grade Decay Heat Removal (OGDHR) system offers an alternate decay heat removal path using the heat removal capacity of the main heat transport system. It is preferred path during

Passive Decay Heat Removal in Liquid-Metal Cooled Reactors
Fusion Technology, 1986The use of liquid-metal, self-cooled blankets in fusion reactors could offer desirable thermal and mechanical characteristics. This study has considered the response of such blankets to a loss-of-flow accident (LOFA) where reactor afterheat is removed via natural convection alone.
