    Interface ScreeningCriteria

    Standardized interface for screening criteria across technical elements.

    This interface consolidates common patterns for screening criteria found in:

    • Initiating Event Analysis
    • Event Sequence Analysis
    • Plant Operating States Analysis
    • Hazard Analysis

    It provides a consistent structure for documenting screening criteria while allowing for technical element-specific extensions.

    const criteria: ScreeningCriteria = {
      frequency_criterion: 1.0e-7,
      basis: "Events with frequency below threshold have negligible risk impact",
      screened_out_elements: [
        {
          element_id: "IE-LOCA-SMALL",
          reason: "Low frequency",
          justification: "Frequency below screening threshold"
        }
      ]
    };
    interface ScreeningCriteria {
        basis: string;
        damage_frequency_criterion?: number;
        elementSpecificProperties?: Record<string, unknown>;
        frequency_criterion?: number;
        risk_criterion?: number;
        screened_out_elements: {
            element_id: string;
            justification: string;
            reason: string;
        }[];
