<p><strong>Abstract:</strong><br />
As Concentrating Solar Power (CSP) technologies aim for higher operating temperatures to enhance efficiency and meet industrial process heat demands, high-temperature metallic materials, including nickel-based superalloys, face challenges in maintaining structural integrity. Advanced ceramics offer a promising alternative due to their superior high-temperature strength. However, accurately assessing the performance of ceramic components requires a fundamentally different approach from that used for metallic components. This Part II of a two-part paper describes the integration of ceramic statistical failure models within <em>srlife</em> – an open-source tool for predicting the life of high-temperature CSP receivers. These models account for the inherent variability in ceramic strength, as well as the effects of subcritical crack growth (SCG) under high temperature cyclic loads. The paper includes an example problem that demonstrates the process of evaluating ceramic receivers using <em>srlife</em>. Part I details the life estimation process for metallic receivers (i.e. creep-fatigue life) along with input and output data structure, thermohydraulic analysis, and structural analysis. The complete tool is available as open-source software at <a class="anchor anchor-primary" href="https://github.com/srlife-project/srlife" rel="noopener" target="_blank"><span class="anchor-text-container"><span class="anchor-text">https://github.com/srlife-project/srlife</span></span></a> and can be installed via the PyPi package manager (<a class="anchor anchor-primary" href="https://pypi.org/" rel="noopener" target="_blank"><span class="anchor-text-container"><span class="anchor-text">https://pypi.org</span></span></a>). By supporting both ceramic and metallic receiver analyses, <em>srlife</em> facilitates fair comparisons between competing metallic and ceramic designs, enabling accurate evaluations of plant efficiency and the economic benefits of ceramic solar receivers and other components.</p>
