Greater-Than-Class C (GTCC) and Transuranic Waste Disposal Chris McKenney, Chief NMSS/DUWP/PAB Telephone No: 301-415-6663 Email: : Christepher.McKenney@nrc.gov

Purpose of Meeting

  • Stakeholder participation and involvement
  • Identification of various technical issues
  • Assist in the development of a regulatory basis for the disposal of GTCC and TRU wastes
  • Supports NRCs openness strategies and cumulative effects of regulation initiatives 9

Low-Level Waste (LLW) and Transuranic Waste 11 Class B

Class A

Class C

GTCC Trans-uranic Waste LLW

Regulatory Basis for GTCC and Transuranic Wastes

  • SRM-SECY-15-0094 - prepare a regulatory basis for the disposal of GTCC waste through means other than deep geologic disposal
  • SRM-SECY-16-0106 - due 6 months after publication of Part 61 supplemental proposed rule 11

Next Steps Complete Part 61 Supplemental Proposed Rule Prepare Regulatory Basis with Public Workshops Potential Part 61 Rule for GTCC and Transuranic Waste Disposal 13

Draft Technical Analysis

  • Assist in the identification of potential hazards, for example o

inventories o

security

  • Assist public to respond to NRC staff questions 14

Reactor Vessels Sealed Sources Glove Boxes 15 Three categories of GTCC waste:

activated metals, sealed sources, and other waste

Activated Metals

  • Metal components from nuclear reactors are most significant source
  • Surface contamination on metal surfaces
  • Activated radionuclides throughout metal
  • Short-lived radionuclides generate heat
  • Some transuranic radionuclides present in surface contamination 15

Sealed Sources

  • Irradiators typically used in medical applications (e.g., hospitals, universities, research) o short lived sources (Cs-137 - 30 year half-life) o transuranic radionuclides (e.g., Pu isotopes)
  • Fissile radionuclides present (Pu-239)
  • Short-lived radionuclides generate heat 16

Other Waste

  • Variety of potential sources, for example:

o potential exhumation of West Valley waste o production of radioisotopes for nuclear imaging procedures (e.g., Mo-99 production)

  • Fissile radionuclides present from Mo-99 production (e.g., Pu-239) 17

GTCC Technical Considerations

  • Thermal Output
  • Gas Generation
  • Fissile Material
  • Long-lived Daughter (Progeny) 18

Radionuclides of Potential Interest based on Draft Analysis (depends on analysis assumptions)

None None Am-241 Pu-239 None None 19

Three Questions

1) What are the important radionuclides that need to be considered for the disposal of the GTCC and transuranic wastes?
2) How might GTCC and transuranic wastes affect the safety and security of a disposal facility during operations (i.e., pre-closure period)?
3) How might GTCC and transuranic wastes affect disposal facility design for post-closure safety including protection of an inadvertent intruder?

Very Low-Level Waste 27

- Coordinate with other agencies on consistency in regulating low activity waste disposal

- Develop guidance that summarizes disposition options for low-end materials and waste

- Promulgate rule for disposal of low-activity waste (now termed very low-level waste)

- Perform LAW Scoping Study (renamed VLLW Scoping Study)

- 20.2002 guidance document revision to improve alternate disposal request process LLW Programmatic Assessment 28

Why Perform a Very Low-Level Waste Scoping Study?

  • Increase in priority

- Changes in timing of decommissioning

  • Recognize the potential opportunity to improve regulatory efficiency and effectiveness
  • Consider alignment with international standards and practices 29
