NRC 10 CFR 61 Update on Low-Level Waste Management 2018 Health Physics Society Midyear Meeting

Office of Nuclear Material Safety and Safeguards (NMSS)

10 CFR Part 61 Rulemaking 2

Why Are We Revising 10 CFR Part 61?

To require low-level waste disposal licensees or license applicants to ensure that low-level waste streams that are significantly different from the low-level waste streams considered in the current Part 61 regulatory basis can be disposed of safely 3

Recent Commission Direction to Staff

  • The staff received direction from the Commission in Staff Requirements - SECY-16-0106 - Final Rule: Low-Level Radioactive Waste Disposal (10 CFR PART 61).
  • The Commission directed the staff to make substantive revisions and republish it as a supplemental proposed rule.
  • Specifically, the Commission directed the staff to:

- 1) Reinstate the use of a case-by-case basis (i.e., "grandfather provision") for applying new requirements;

- 2) Reinstate the 1,000 year compliance period from the proposed rule and adopt a longer period of performance assessment;

- 3) Clarify that the safety case consists of the quantitative performance assessment, as supplemented by consideration of defense-in-depth measures; and 4

Recent Commission Direction to Staff (cont.)

  • Specifically, the Commission directed the staff to:

- 4) Modify the text addressing defense-in-depth to solely providing additional assurance in mitigating the effects of large uncertainties; and

- 5) Be informed by broader and more fully integrated, costs and benefits resulting from the proposed rule changes, including pass-through costs to waste generators and processors.

  • Issued Federal Register Notice (82 FR 48283) on October 17, 2017 requesting public input
  • Had public meeting on October 19, 2017
  • Staff is evaluating these comments 5

Planned Amendments to 10 CFR Part 61

  • Adds requirement for site-specific analyses
  • Introduces a compliance period of 1,000 years for traditional low-level waste
  • Adds an analysis for long-lived low-level waste for a post-1,000-year performance period
  • Allows flexibility for Agreement States to analyze longer timeframes
  • Stresses the use of defense-in-depth to mitigate uncertainties in technical analyses
  • Restores grandfathering provision 6

Next Steps

  • Staff is developing revised rule language
  • Staff will present supplemental proposed rule to Commission
  • Staff will issue supplemental proposed rule for 90-day comment period
  • Staff will consider comments and develop draft final rule for Commissions consideration 7
