Lead‐based fast reactor is one of the most promising fourth‐generation nuclear energy
systems. Fuel assembly design is a key technology for the research and development of …

With the deployment of advanced and small modular reactors (SMRs), it is important to
develop the tools to assess their safety. This work presents the different components of a …

The recent development of small modular reactors needs to be followed by safety analysis
using the newest available tools. This work focuses on one type of reactor, SEALER, which …

A sensitivity and uncertainty analysis was performed on a small lead cooled reactor for two
types of transients: an unprotected loss of flow (ULOF) and unprotected transient overpower …

Abstract SEALER (SwEdish Advanced Lead Reactor) is a passively safe lead-cooled reactor
designed for commercial power production, under design by the LeadCold company. The …

Na atual crise climática, a energia nuclear, aliada às fontes renováveis, deverá ser uma das
principais alternativas técnicas para descarbonizar as redes elétricas mundiais. No entanto …

Small Modular Reactors (SMRs) are defined by the IAEA as “newer generation reactors
designed to generate electric power typically up to 300MW, whose components systems can …

Abstract Breed and Burn (B&B) reactors are a special class of fast reactor that promises
enormous sustainability and proliferation-resistance benefits compared to current …

ABSTRACT A model based on the SEALER reactor was developed in the SERPENT 2.1. 32
nuclear code with two major differences from the original project: the central fuel assembly …

This thesis work is about the dynamical behavior of advanced nuclear systems, in particular
lead-cooled fast reactors (LFRs). As they are currently under study and development, it is …
