A key integration challenge is that the nuclear facility cannot function as a standalone object. It requires a reliable access corridor for construction, operation, deliveries, and emergency response. This makes the road (pavement) + steel truss bridge<\/strong> central to the system because they physically connect the containment site to the historical building and the broader transport network. In parallel, the historical building cannot be reused without structural intervention: it needs a new roof structure and must satisfy the municipality\u2019s requirement of a minimum 10% green roof coverage<\/strong>, which adds dead load and can trigger strengthening needs.<\/p>\n\n\n Fig.1 <\/p>\n\n\n\n To address the tender requirement, the integrated system is evaluated through two coupled value drivers: CO\u2082 performance<\/strong> (municipality objective) and economic viability<\/strong> (project objective). From the municipality\u2019s perspective, the best proposal achieves the lowest combined CO\u2082 footprint while still providing a safe, functional facility and refurbished historic asset. From the developer\u2019s perspective, profitability is determined by lease income from the containment facility and the renovated building compared with construction and material costs for the containment structure, bridge, pavement works, and the historic building retrofit.<\/p>\n\n\n\n Based on our current model, the integration is driven by the following design-change inputs<\/strong> in fig.2. <\/p>\n\n\n Fig. 2<\/strong><\/p>\n\n\n\n These are the parameters that actively change the geometry and therefore shift CO\u2082 and cost:<\/p>\n\n\n\n The bridge length<\/strong> (directly linked to the position of the bridge<\/strong>) is a primary integration driver. Changing bridge position\/length changes:<\/p>\n\n\n\n This means bridge placement is not only a layout choice, but a cost\/CO\u2082 lever that also affects the road system through derived lengths.<\/p>\n\n\n\n Instead of using reactor size as the main variable, the containment building is parametrized through its wall geometry:<\/p>\n\n\n\n Its size is controlled by a radius parameter<\/strong> (with a fixed height of 45 m<\/strong> and a minimum radius range 17\u201318 m<\/strong> required by the project constraints).<\/p>\n\n\n\n These geometry changes scale the concrete quantity and therefore directly affect:<\/p>\n\n\n\n The roof retrofit is modeled as a coupled system rather than a single \u201cgreen roof\u201d slider. The key changing inputs are:<\/p>\n\n\n\n Green Roof System<\/strong><\/p>\n\n\n\n These control the added dead load and therefore influence structural demand.<\/p>\n\n\n\n Together, these elements form a single integrated system because none of the subsystems can be optimized independently. For example, moving the bridge to reduce span length may reduce steel and cost but increase (or decrease) the pavement length and associated emissions. Increasing green roof coverage improves tender alignment but raises roof dead load, which can push the timber truss system and masonry bays toward strengthening measures. Increasing containment wall radius or height increases concrete volume and embodied CO\u2082, which can dominate the project footprint unless offset by reductions elsewhere. The final design is therefore selected by comparing combined system outcomes<\/strong> across CO\u2082 and cost, with the primary objective of winning the tender on emissions while keeping the project internally viable.<\/p>\n\n\n\n By combining the ontology structure with the Dynamo computations, the project becomes transparent and reproducible:<\/p>\n\n\n\n This makes it easy to explain why a configuration performs well (or fails), and it makes it straightforward to extend the model with additional requirements or parameters if the group decides to add them.<\/p>\n","protected":false},"excerpt":{"rendered":" Integration Context This project develops an integrated system for constructing a new nuclear containment facility on a constrained site while meeting a municipal tender requirement for minimum CO\u2082 emissions.
