NUCLEAR WASTE TREATMENT ASSESSMENTS OF WASHINGTON STATE'S HANFORD SITE ; NUCLEAR WASTE TREATMENT ASSESSMENTS OF WASHINGTON STATE'S HANFORD SITE ; Library of Congress Cataloging-in-Publication Data; CONTENTS ; PREFACE; Chapter 1 HANFORD WASTE TREATMENT PLANT: DOE NEEDS TO TAKE ACTION TO RESOLVE TECHNICAL AND MANAGEMENT CHALLENGES ; ABBREVIATIONS ; WHY GAO DID THIS STUDY ; WHAT GAO RECOMMENDS ; WHAT GAO FOUND ; BACKGROUND ; SIGNIFICANT TECHNICAL CHALLENGES REMAIN UNRESOLVED ; SUBSTANTIAL ADDITIONAL COST INCREASES AND SCHEDULE DELAYS ARE LIKELY.
DOE Has Not Yet Fully Estimated the Cost and Schedule Impact of Resolving Technical ChallengesProject Cost and Schedule Increases Could Be Partially Offset by Opportunities for Savings ; DOE IS TAKING STEPS TO ADDRESS SOME MANAGEMENT AND OVERSIGHT PROBLEMS BUT CONTINUES TO FACE CHALLENGES TO COMPLETING THE WTP ; DOE Is Taking Steps to Improve the Management and Oversight of the WTP Project ; DOE's Fast-Track, Design-Build Management Approach and Other Management and Oversight Problems Have Led to Cost Increases and Schedule Delays ; CONCLUSION ; RECOMMENDATIONS FOR EXECUTIVE ACTION.
AGENCY COMMENTS AND OUR EVALUATION End Notes ; Chapter 2 HANFORD CLEANUP: CONDITION OF TANKS MAY FURTHER LIMIT DOE'S ABILITY TO RESPOND TO LEAKS AND INTRUSIONS ; ABBREVIATIONS ; WHY GAO DID THIS STUDY ; WHAT GAO RECOMMENDS ; WHAT GAO FOUND ; BACKGROUND ; History of Hanford Tanks ; Contents of the Tanks ; Tank Regulations and Oversight ; CONDITION OF TANKS IS WORSE THAN ASSUMED UNDER DOE'S CURRENT SCHEDULE FOR RETRIEVING TANK WASTE ; Condition of SSTs Is Worse Than Previously Assumed, with 1 Leaking and Water Infiltrating at Least 14.
DOE HAS TAKEN AND PLANNED SEVERAL ACTIONS TO RESPOND TO RECENT LEAKS AND INTRUSIONS, INCLUDING MODIFYING ITS TANK MONITORING AND INSPECTION PROCEDURES For SSTs, DOE Has Conducted Additional Inspections and Modified Its Tank Monitoring Procedures; For DSTs, DOE Has Conducted Additional Inspections, Convened an Expert Panel, and Developed a Pumping Plan for AY-102; DOE'S CURRENT WASTE RETRIEVAL SCHEDULE DOES NOT ACCOUNT FOR THE WORSENING CONDITION OF THE TANKS OR WTP DELAYS.
DOE's Retrieval Schedule Does Not Account for the Worsening Condition of Tanks and Growing Demand on the Limited DST Space DOE's Retrieval Schedule Does Not Account for Recently Acknowledged WTP Delays, and the Extent to Which the Tanks Can Continue to Safely Store Waste Is Unknown ; CONCLUSION ; RECOMMENDATIONS FOR EXECUTIVE ACTION ; AGENCY COMMENTS AND OUR EVALUATION ; APPENDIX I: AGE AND RETRIEVAL SCHEDULE FOR HANFORD SINGLE-SHELL TANKS ; APPENDIX II: TIMELINE OF HANFORD DOUBLE- SHELL TANKS ; End Notes.
