Objective Provide some brief background on NRC’s 10 CFR Part 61 RulemakingSummarize stakeholder comments received to date
Discuss the schedule and next steps for the NRC’s review2Slide3

4
Rationale for Current RulemakingLarge quantities of depleted uranium (especially from enrichment facilities) LLW from Department of Energy operationsWaste forms/volumesBlended LLW (greater quantities than previously expected)New technologies might generate unexpected LLW waste streamsSlide5
Major changes in the proposed rule (10 CFR Part 61)
1,000 year compliance periodInadvertent Intruder analysisProtective Assurance analysisLong-lived LLW analysis for performance period beyond 10,000 years5Slide6
Major changes in the proposed rule (

Comments Received
Use of current ICRP methodology and what that might imply. Others agreed with proposal to use latest ICRP methodology.Compatibility B designation for major portions of the proposed rule.Long term siting stability. The intruder dose and related assumptions.The phantom four (C-14, Tc-99, I-129, & H-3). Second rulemaking on waste classification. 8Slide9
Comments Received (cont’d)
Applicability of new requirements to existing sites. Reduce complexity by moving more information to the guidance document. Two-tiered approach would be simpler and better.Supplemental environmental impact statement needed.Transparency and availability of performance assessments. Cost benefit analysis needed. 9Slide10
Next Steps
Initial comment period ended on July 24, 2015Comment period reopened to address extension requests receivedReopened comment period expired September 21, 2015Final rule to be sent to Commission by May 2016Staff will then develop recommendation to Commission on need for second rulemaking on revising waste classification tables10Slide11
