However the structural integrity challenges for such high temperature plant have been demonstrated in experimental Generation IV plant and the AGR fleet in the UK. Ensuring the design codes are fit for purpose to satisfy the UK regulatory...

... Abstract Excessive dependence on the safety factor of deterministic analysis leads to the conservative design of industrial components, resulting in conspicuous waste of manufacturing resources. The novel strategy for probabilistic assessments for structural integrity is proposed based...

... Abstract Next-generation Advanced Modular Reactors are expected to aid in the worldwide transition to net-zero emissions. However, these reactors are designed to operate at very high temperatures, which makes the structural integrity of the reactor critical to its design. The structural...
