1. Integration of Safety into the Design Process Overview of DOE-STD-1189 Richard Black, Director Office of Nuclear & Facility Safety Policy

2. Integration of Safety Into Design 1189: Why?  New DOE projects experienced safety design questions resulting in reanalysis, rework and added cost  DOE and EFCOG agreed that DOE guidance on safety design criteria and expectations should be enhanced  Deputy Secretary committed to the DNFSB to develop additional guidance

3. Who is developing 1189?  DOE and EFCOG agreed to jointly develop new standard/guidance  Working Group consisting of HQ, Field, CTA, EH, EFCOG (SAWG and EPWG) writing standard (DNFSB observing)  Draft 1189 will be informally reviewed by SMEs before submitting to RevCom

4. 1189: When?  Draft currently under development by Working Group  Sept: Informal review by SMEs and DNFSB  October: Submittal into RevCom  January: Final publication  July: DOE O 413.3 effective date

5. 1189: Key Objectives  Implements safety-in-design philosophies in DOE O 413.3, Project Management  Incorporates facility safety criteria in DOE O 420.1B, Facility Safety  Ensures that hazards are identified and evaluated, and safety approach defined early in the project  Projects include new nuclear facilities and major modifications to existing facilities  Uses an integrated project team to design safety into the facility (key: DOE early involvement and approval of safety approach)

6. 1189: Guiding Principles  DOE O 420.1 safety design requirements must be addressed  Project team must include safety and design experts  Project team must interface with other functional areas (e.g., security, worker safety, QA) that might affect design  Early project decisions should be reasonably conservative  Risk and opportunity analysis must address project safety design contingencies and mitigation strategies

7. 1189: Safety/Design Control Strategies and Priorities  Minimize hazardous materials (MAR)  Select engineered features (structures, systems and components (SSCs)) over administrative controls  Select passive SSCs over active  Select preventive over mitigative controls  Select controls closest to the hazard  Select controls that address multiple hazards

8. 1189: Documentation for Decisions  Critical Decision (CD) packages must provide sufficient documentation and justification for safety technical basis, selected safety systems, and risk/cost contingencies  Documents must address safety functions and strategies for: building confinement, seismic design, ventilation, fire protection, security, life safety, criticality, and emergency power.

9. 1189:Evolution of Documentation  The project safety and design basis will evolve through project stages CD-0, 1 and 2 as more information is available  Expectation is that surprises will be minimized by sufficient hazard evaluations, definition of safety functions, identification of control strategies, selection of safety systems, and development of risk and opportunity strategies.

10. 1189: Subjects Addressed  Project Integration and Planning  Safety Considerations for the Design Process Pre-Conceptual Planning (CD-0) Conceptual Design Phase (CD-1) Preliminary Design Phase (CD-2) Final Design Phase (CD-3)  Safety Considerations for Transition/Closeout Phase (CD-4)

11. 1189: Subjects Addressed- Continued  Safety Program Interfaces (e.g., worker safety, security, emergency preparedness, radiological protection, human factors, QA, waste management, etc.)  Additional Safety Integration Considerations (e.g., Facility Modifications, Government Furnished Equipment)

12. Additional Guidance in Appendices  Appendix A: Safety System Design Criteria (specifies methodologies to determine safety class and collocated worker safety significant SSCs; and seismic design criteria)  Appendix B: Chemical Hazard Evaluation  Appendix C: Facility Worker Hazard Evaluation
