Analysis on passive residual heat removal system with heat pipes for longterm decay heat removal of small lead-based reactor [PDF]

E3S Web of Conferences, 2021
.A lead-based reactor with employing heat pipes as passive residual heat removal system (PRHRS) for longterm decay heat removal was designed. Three-dimensional computational fluid dynamics (CFD) software FLUENT was adopted to simulate the thermal-hydraulic characteristics of the PRHRS under Station-Black-Out (SBO) accident condition. The results showed

Development of probabilistic risk assessment methodology against strong wind for sodium-cooled fast reactors

Mechanical Engineering Journal, 2023
For nuclear power plants, probabilistic risk assessment (PRA) should be performed not only against earthquake and tsunami, which are critical events especially in Japan, but also other external hazards such as strong wind. The aim of the present study is

Analysis of ESFR Decay Heat Removal Systems in Protected Station Blackout

Journal of Nuclear Engineering and Radiation Science, 2021
Abstract As part of the European sodium fast reactor (ESFR)-safety measures assessment and research tools (SMART) project, safety assessments are being conducted on the updated ESFR design. An important part of the study is the evaluation of the reactor's behavior within hypothetical accidental conditions to assess and ensure that the ...

Dynamic Hybrid Reliability Studies of a Decay Heat Removal System [PDF]

International Journal of Reliability, Quality and Safety Engineering, 2015
Some critical safety systems exhibit the characteristics of hybrid stochastic class whose performance depends on the dynamic interactions of deterministic variables of physical phenomena and probabilistic variables of system failures. However, conventional probabilistic safety assessment (PSA) method involves static event and linked fault tree analysis
