NRCs Review of the Hanford WMA-C Draft Waste Incidental to Reprocessing (WIR) Evaluation October 16, 2018 Chris McKenney Division of Decommissioning, Uranium Recovery and Waste Programs U.S. Nuclear Regulatory Commission
Overview
- NRCs role at Hanford
- Criteria
- Products
- Schedule 2
What is WIR? (theory)
WIR is waste that would be high-level waste (HLW) based on its reprocessing origin, but can be managed as low-level waste because of the lower level of risk it poses. Lower risk can result from:
- Separation and, in some cases, further decontamination of low-level fraction of waste
- Residuals of a higher-activity fraction, left in place and further stabilized 3
NRCs Role at Hanford
- Review of Waste Management Area C (WMA-C) draft WIR Evaluation
- Interagency agreement at Hanford (consultation)
- NRC will not have a monitoring role at Hanford 4
NRCs Role at Hanford
- DOE submits its draft WIR Evaluation to NRC for review.
Consultation typically includes:
- Scoping meetings or technical exchanges
- Requests for Additional Information
- NRC Technical Evaluation Report (TER)
Consultation 5

Criteria for Determining Reprocessing Waste is WIR (i.e., not HLW)
- Three sets of similar criteria:
- Hanford - DOE Manual 435.1-1
- West Valley - NRC West Valley Policy Statement
- SRS and INL - National Defense Authorization Act for 2005 (NDAA),
Section 3116
- The criteria are generally consistent:
- All require removing key radionuclides to the maximum extent practical (or technically and economically practical)
- All require disposal to meet the performance objectives of (or comparable to) 10 CFR Part 61 (DOE Manual 435.1-1 also has alternative requirements for waste identified as TRU) 7
Performance Objectives of 10 CFR Part 61, Subpart C
- §61.41 Protection of the general population from releases of radioactivity (dose limit & ALARA)
- § 61.42 Protection of individuals from inadvertent intrusion
- § 61.43 Protection of individuals during operations
- § 61.44 Stability of the disposal site after closure 8

What is Reviewed
- Staff conducts completeness review of documents submitted
- Staff review the draft WIR evaluation document.
- Staff review the supporting documents (first level).
- Staff review secondary and lower level documents as needed.
- Staff review the performance assessment model, incorporated assumptions, supporting calculations, and model support.
- Staff may develop an independent model to develop risk insights.

What is Reviewed 10
How is it Reviewed
- Staff uses NUREG-1854 to guide the review.
- NUREG-1854 provides areas of review and review procedures.
- ML072360184, 228 pages 11
How is it Reviewed
- NRCs review is open and transparent.
- Documents are publically available.
- Basis for requests for additional information is provided.
- A report (technical evaluation report) is developed to document the results of the review.
- Documents can be accessed through ADAMS, enter docket number PROJ0736 in the search box.
12
Other Considerations for the Review
- DOE indicated although the entire draft WIR evaluation is subject to consultation, DOE requested emphasis on criteria 2 (performance objectives) over criteria 1 (removal of key radionuclides).
- DOE requested that NRC determine if DOE demonstrated a reasonable expectation of compliance with the performance objectives for 1,000 years.
- Model results to 10,000 years provided to support risk-informed decision-making.
13
Schedule
- Receive draft WIR evaluation - June 4, 2018
- NRC transmits completeness review letter - July 19, 2018
- Public meeting on RAIs
- Note: If DOE requires additional time to address RAI responses, the schedule will need to be adjusted
Concluding Remarks
- NRC is an independent federal agency whose decision is based solely on the merits of the materials provided.
- NRC strives to provide a clear and technically-sound basis for findings.
