Design Calculations for Containment Structures

Design Calculations for Containment Structures 6.3.1 General Criteria... 

The data analysis module of ELECTRAS is twofold. One part was designed for general statistical data analysis of numerical data. The second part offers a module For analyzing chemical data. The difference between the two modules is that the module for mere statistics applies the stati.stical methods or rieural networks directly to the input data while the module for chemical data analysis also contains methods for the calculation ol descriptors for chemical structures (cl. Chapter 8) Descriptors, and thus structure codes, are calculated for the input structures and then the statistical methods and neural networks can be applied to the codes. 

Technical evaluation of options and consequence and risk analyses may be prepared. The analyses might include calculation of consequence severities for possible incidents. Subsequently, the basis for a mitigation system may be generated. This might involve, for example, a secondary containment structure, explosion suppression system, or scrubber. The rationale and technical design basis for such decisions should be documented and retained as part of the process knowledge. 

The polymers shown in Figure 17.4 each contain a structural unit whose contribution to ECoh(Fed°rs) is not listed in the group contribution tables [4,5], so that Ecoh(Fedors) cannot be calculated for these polymers by using group contributions. Calculations of E for these seven polymers by using the new correlations (equations 5.10-5.12 for the general-purpose correlation, and Equation 17.3 for the designer correlation) are summarized in Table 17.4.
