Reliability studies of decay heat removal system

2010 2nd International Conference on Reliability, Safety and Hazard - Risk-Based Technologies and Physics-of-Failure Methods (ICRESH), 2010
Passive systems have been implemented in most of the advanced reactors in order to improve the availability of the plant. In this paper the methodology used for performing the passive system reliability analysis has been discussed. A case study on passive decay heat removal system of large sized PHWRs has also been discussed.

INNOVATIVE RADIATION-BASED DECAY HEAT REMOVAL SYSTEM

open access: yes, 2012
One of the main issues, regarding the development of Generation IV nuclear power plants, is the safety. In order to design nuclear systems characterized by enhanced safety features, an innovative and passive system, aimed at decay heat removal, especially suitable for sodium cooled fast reactors, has been developed. The attention is here mainly focused

Impact of Wind Velocity on the Performance of the RVACS Decay Heat Removal System

open access: yesNuclear Technology, 1997
The impact of wind velocity on the performance of the reactor vessel auxiliary cooling system (RVACS) of an advanced liquid-metal reactor design is analyzed, and design modifications that mitigate adverse wind effects are investigated. In the reference design, the reactor is served by four communicating RVACS stacks, and each stack has two air inlets ...

Investigations of accelerator reliability and decay heat removal for accelerator-driven system

Annals of Nuclear Energy, 2019
Abstract To 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 proposed to reduce the beam-trip frequency.

Hydrodynamics and heat transfer characteristics of passive decay heat removal systems: CFD simulations and experimental measurements

open access: yesChemical Engineering Science, 2010
In nuclear safety operations, condensing heat transfer area is placed in a large pool of liquid to accommodate passive thermal decay. Such systems are subject to pool boiling and thermal stratification. Velocity and temperature measurements were carried out in a 300 mm i.d. vessel with a central tube as the heat transfer area.
