RELAP5 assessment on CIRCE decay heat removal experiments
2014DHR experiments were carried out on the large scale LBE-cooled CIRCE facility at the ENEA/Brasimone center to verify the decay heat removal through heat exchangers immersed in the LBE pool under representative accidental conditions, and provide a valuable database for both CFD and system code assessment.

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

Transient Analysis of Passive Decay Heat Removal System for CEFR
Volume 2: Plant Systems, Construction, Structures and Components; Next Generation Reactors and Advanced Reactors, 2013A passive decay heat removal system (DHRS) has been installed on Chinese Experimental Fast Reactor (CEFR). To well predict the thermal-hydraulics behavior of DHRS in transient, an integrated model has been developed for CEFR by using OASIS code. The model included the main thermal transfer system and DHRS circuit.

Analysis of DRACS and DRACS-RVACS Decay Heat Removal Experiments
Nuclear Technology, 1991This paper reports on two large-scale decay heat removal experiments analyzed to support the validation of the thermal-hydraulic code COMMIX and the design of advanced liquid metal reactors (ALMRs). The experiments were performed in the reactor vessel auxiliary cooling system (RVACS) test facility, which provides a scaled simulation of the passive ...

Scaling of Natural Circulation Decay Heat Removal From Coolant Pools
Thermal Hydraulics of Advanced Nuclear Reactors, 1994Abstract This paper presents the generic features together with the basic physical phenomena of nuclear decay heat removal from large coolant pools by natural circulation. Using dimensionless numbers such as the Richardson number, the Stanton number and a relevant time scale, the local and the overall thermo-hydraulic aspects of pool ...

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 ...
