  3. AU-31 Functions Nuclear Safety Basis & Facility Design AU-31

  4. AU-31Recent Accomplishments Issued DOE Order 420.1C, Chg 2 (Facility Safety) July 2018 Issued DOE-STD-1027-2018 (Hazards Categorization) Issued DOE-HDBK-1224-2018 (Hazard & Accident Analysis) Issued Notice of Proposed Rulemaking (NOPR) for revision of 10 CFR 830, Subpart B (Safety Basis Requirements) Approved PJS to revise DOE-STD-1195-2008 (SS SIS Design) Approved PJS to develop DOE-STD-XXXX for DOE Reactor DSA Provided seven Roll-out Trainings on DOE-O 420.1C, Chg 2 and STD 1189-2016 (OR, SR, LANL, RL, EFCOG, ID, HQ) Pending final concurrence for issuance of DOE-STD-1228 (HC-3 Nuclear Facility DSAs)

  5. AU-31Accomplishments (Cont.) • Pending Approval of PJS for revision of DOE-HDBK-1163-2003 (Integration of Multiple Hazard Analysis Requirements & Activities) – working with AU-11 • Draft DOE-Guide 424.1C (USQ) in RevCom for comment • PJS for new HDBK for DOE-EH-0545 (Seismic Eval of SSCSs) in RevCom for comment • Conducted Workshops on Chemical Safety and on Facility Hazard Categorization

  6. AU-31Ongoing Activities Prepare training slides for DOE-HDBK-1224 (AA Handbook) Develop Revision of DOE-HDBK-3010 (ARFs/RFs) Develop Revision to DOE-HDBK-1169 (Nuc Air Cleaning) Develop Revision of DOE-STD-1195 (SS SIS design) Approval of Change to 10 CFR 830, Subpart B (Safety Basis Requirements); Provide Roll-out Training, as needed Issue Revision to DOE G 424.1C (USQ) after 10 CFR 830 change; Provide Roll-out Training, as needed Issue Revision to DOE-STD-1104-2016 (Review and Approval of Nuclear Facility Safety Basis & Safety Design Basis Documents) after 10 CFR 830 change

  7. AU-31Ongoing Activities (Cont.) Develop new DOE-STD-xxxx for Reactor DSA Develop new HDBK-xxxx for DOE-EH-0545-1997 (Seismic Evaluation Procedures) Issue OE-3 Bulletin for Chemical Spray Release Holdrevision of DOE-STD-3014 (Air Craft Crash) - evaluate alternate methodology for screening Evaluate scope of revision for HDBK-1132-99 (Design Considerations) Develop Revision to DOE-HDBK-1163-2003 (Integration of Multiple Hazard Analysis Requirements & Activities)

  8. AU-31Ongoing Activities (Cont.) Initiate Revision to DOE-STD-1027-2018 (Hazard Categorization) Consider Revision of DOE-STD-3009-2014 (DSA Safe Harbor) to address chemical safety programs

  9. AU-31 Program Update Major Changes in Recently Issued DOE Standard Revisions

  10. Major ChangesDOE Order 420.1C, Chg 2, Facility Safety • Added Sec 6 for listing all invoked standards • Added Sec 7 for defining Applicable Standards • Updated reference to: • DOE-STD-1189-2016 • DOE-STD-1104-2016 • DOE-STD-1020-2016 • DOE-STD-3007-2017 • DOE-STD-1066-2016

  11. Major ChangesDOE Order 420.1C, Chg 2, Facility Safety Clarified applicability for leased facilities (Sec 3.a and Att 1, 1.c) Clarified guidance for use of active confinement system (Att 2, Ch I, 3.b.(3)(c) Clarified Field Element’s responsibility to determine Att 2, Ch II requirements for leased facilities that are not nuclear hazard category 1, 2 and 3 (Att 2, Ch II, 2) Clarified relief provision for exemptions/ equivalencies from applicable codes and standards (Att 2, Ch II, 3.a.(2) Clarified relief provision for DOE-STD-1066-2016, which is designated as applicable standard.

  12. Major ChangesDOE-STD-1027-2018Hazard Categorization of DOE Nuclear Facilities The Standard was revised to use more recent International Commission for Radiation Protection (ICRP) publications for updated dose coeffiecients The revision does not modify the methodology for calculation of Threshold Quantities (TQs) to maintain consistency with the methodology of DOE-STD-1027-92, CN 1.

  13. Major ChangesDOE-STD-1228-201x Developed draft DOE-STD-1228, Preparation of DSA for HC-3 Nuclear Facilities, to clarify the graded approach with respect to 10 CFR Part 830, as it applies to development of DSAs for HC-3 nuclear facilities. Many of the requirements are drawn from DOE-STD-3009-2014 and provided detail guidance/interpretations for graded approach.

  14. DOE-HDBK-3010 Update

  15. DOE-HDBK-3010 Update • “New” includes any new information since the original 1994 issuance of HDBK-3010-94 • Most sections will be updated to include new information but will not change the recommended bounding ARF/RF values • Minimizing changes to remainder of document with a few exceptions including: correct known errors, correct outdated information regarding DOE policy, delete “must/shall” statements

  16. DOE-HDBK-3010 Update • Projected Schedule: • Ongoing-May: Senior Review Committee review and comment resolution • June-July and comment resolution: SME independent technical review • August-September: Pre-Revcom stakeholder review • October/November: Release to Revcom for 60-day review POC: Caroline Garzon, caroline.garzon@hq.doe.gov

  17. Spray Leak Technical Report • DRAFT OE-3: “Pressurized Spray Leak Technical Report” • Purpose: To inform the complex of the issuance of U.S. Department of Energy (DOE) Pressurized Spray Release Technical Report. • Technical report documents DOE’s analytical and experimental work on spray leak phenomena from 2009 to the present, and provides technical findings and recommendations based on that work. • The report evaluates DOE’s technical basis for DOE-HDBK-3010-94, Airborne Release Fractions/Rates and Respirable Fractions for Nonreactor Nuclear Facilities, Section 3.2.2.3.1, “Venting Below the Liquid Level,” and provides both a clarification on the application of the bounding 1E-4 airborne release fraction (ARF) and respirable fraction (RF) and a new conservative analytical method for evaluating pressurized spray leak phenomena based on testing conducted by PNNL. • Status: The draft OE-3 is undergoing AU review POC: Caroline Garzon, caroline.garzon@hq.doe.gov

  18. Conclusions Significant activity completed and ongoing Success is only possible by partnering with user community (programs, field, contractors, EFCOG) Assistance continues to be an important priority Feedback is needed and welcome
