Book Description
Reliability analysis of passive systems is the process of assessing the probability of a passive system performing its intended function without failure, over a specified period of time, under specified conditions. A passive system is a system that does not require external energy input to function, such as a safety valve, a thermal insulation system, or a passive cooling system. The reliability analysis of passive systems involves the identification of failure modes and mechanisms that could occur, the determination of failure rates for each component, and the calculation of the system reliability using methods such as fault tree analysis, event tree analysis, or Monte Carlo simulation. The analysis typically starts with a comprehensive review of the system design, including the identification of all components, their functions, and their interdependencies. This is followed by a review of available data on component failure rates, failure modes, and mechanisms, which can be obtained from industry databases, component manufacturers, or relevant literature. Once the failure rates for each component are determined, they are combined using appropriate mathematical models to calculate the overall system reliability. The results of the analysis are used to identify critical components that may require additional testing, inspection, or maintenance, and to optimize the system design to improve overall reliability. Reliability analysis of passive systems is particularly important in industries where safety and reliability are paramount, such as nuclear power plants, chemical processing plants, and aerospace. A thorough and accurate reliability analysis can help to minimize the risk of system failures, improve safety, and reduce costs associated with maintenance and downtime.

Book Description
The latest iterations of advanced reactor designs have included increased reliance on passive safety systems to maintain plant integrity during unplanned sequences. While these systems are advantageous in reducing the reliance on human intervention and availability of power, the phenomenological foundations on which these systems are built require a novel approach to a reliability assessment. Passive systems possess the unique ability to fail functionally without failing physically, a result of their explicit dependency on existing boundary conditions that drive their operating mode and capacity. Argonne National Laboratory is performing ongoing analyses that demonstrate various methodologies for the characterization of passive system reliability within a probabilistic framework. Two reliability analysis techniques are utilized in this work. The first approach, the Reliability Method for Passive Systems, provides a mechanistic technique employing deterministic models and conventional static event trees. The second approach, a simulation-based technique, utilizes discrete dynamic event trees to treat time- dependent phenomena during scenario evolution. For this demonstration analysis, both reliability assessment techniques are used to analyze an extended station blackout in a pool-type sodium fast reactor (SFR) coupled with a reactor cavity cooling system (RCCS). This work demonstrates the entire process of a passive system reliability analysis, including identification of important parameters and failure metrics, treatment of uncertainties and analysis of results.

Book Description
The book has been developed in conjunction with NERS 462, a course offered every year to seniors and graduate students in the University of Michigan NERS program. The first half of the book covers the principles of risk analysis, the techniques used to develop and update a reliability data base, the reliability of multi-component systems, Markov methods used to analyze the unavailability of systems with repairs, fault trees and event trees used in probabilistic risk assessments (PRAs), and failure modes of systems. All of this material is general enough that it could be used in non-nuclear applications, although there is an emphasis placed on the analysis of nuclear systems. The second half of the book covers the safety analysis of nuclear energy systems, an analysis of major accidents and incidents that occurred in commercial nuclear plants, applications of PRA techniques to the safety analysis of nuclear power plants (focusing on a major PRA study for five nuclear power plants), practical PRA examples, and emerging techniques in the structure of dynamic event trees and fault trees that can provide a more realistic representation of complex sequences of events. The book concludes with a discussion on passive safety features of advanced nuclear energy systems under development and approaches taken for risk-informed regulations for nuclear plants.

Book Description
A comprehensive risk-informed methodology for passive safety system design and performance assessment is presented and demonstrated on the Flexible Conversion Ratio Reactor (FCRR). First, the methodology provides a framework for risk-informed design decisions and as an example two design options for a decay heat removal system are assessed and quantitatively compared. Next, the reliability of the system is assessed by quantifying the uncertainties related to system performance and propagating these uncertainties through a response surface using Monte Carlo simulation. Finally, a sensitivity study is performed to measure the relative effects of each parameter and to identify ways to maintain, improve, and monitor system performance.
