Abstract
The U.S. Department of Energy (DOE) announces the availability of the Draft Basis for Section 3116 Determination for Closure of the Calcined Solids Storage Facility at the Idaho National Laboratory Site (Draft CSSF 3116 Basis Document). The Draft CSSF 3116 Basis Document demonstrates that the Calcined Solids Storage Facility (CSSF) at closure after waste retrieval is not high-level radioactive waste (HLW) and may be disposed of in place as low-level radioactive waste (LLW). DOE prepared the Draft CSSF 3116 Basis Document pursuant to Section 3116 of the "Ronald W. Reagan National Defense Authorization Act for Fiscal Year 2005" (hereafter NDAA Section 3116). DOE is consulting with the U.S. Nuclear Regulatory Commission (NRC), and is also making the Draft CSSF 3116 Basis Document available for comments from states, Tribal Nations, stakeholders, and the public. After consultation with the NRC, carefully considering comments received, and performing any necessary revisions of analyses and technical documents, DOE will prepare a final CSSF 3116 Basis Document. Based on the final document, the Secretary of Energy, in consultation with the NRC, may determine in the future whether the stabilized CSSF bins (including integral equipment), transport lines, and any residual waste remaining therein at closure are non-HLW and may be disposed of in place as LLW.

DEPARTMENT OF ENERGY
Notice of Availability of Draft Basis for Section 3116
Determination for Closure of the Calcined Solids Storage Facility at
the Idaho National Laboratory Site, Idaho
AGENCY: Department of Energy.
ACTION: Notice of availability.
-----------------------------------------------------------------------
SUMMARY: The U.S. Department of Energy (DOE) announces the availability
of the Draft Basis for Section 3116 Determination for Closure of the
Calcined Solids Storage Facility at the Idaho National Laboratory Site
(Draft CSSF 3116 Basis Document). The Draft CSSF 3116 Basis Document
demonstrates that the Calcined Solids Storage Facility (CSSF) at
closure after waste retrieval is not high-level radioactive waste (HLW)
and may be disposed of in place as low-level radioactive waste (LLW).
DOE prepared the Draft CSSF 3116 Basis Document pursuant to Section
3116 of the ``Ronald W. Reagan National Defense Authorization Act for
Fiscal Year 2005'' (hereafter NDAA Section 3116). DOE is consulting
with the U.S. Nuclear Regulatory Commission (NRC), and is also making
the Draft CSSF 3116 Basis Document available for comments from states,
Tribal Nations, stakeholders, and the public. After consultation with
the NRC, carefully considering comments received, and performing any
necessary revisions of analyses and technical documents, DOE will
prepare a final CSSF 3116 Basis Document. Based on the final document,
the Secretary of Energy, in consultation with the NRC, may determine in
the future whether the stabilized CSSF bins (including integral
equipment), transport lines, and any residual waste remaining therein
at closure are non-HLW and may be disposed of in place as LLW.
DATES: DOE invites comments on the Draft CSSF 3116 Basis Document
during a 45-day comment period beginning the calendar day after
publication of this Notice of Availability. A public virtual meeting on
the Draft CSSF 3116 Basis Document will be held on a date to be
announced, currently anticipated to be November 1, 2023. Before the
meeting, DOE will issue stakeholder and media notifications and publish
a notice in the local newspaper providing the date, time, and virtual
platform information of the public meeting. Information on the public
meeting date and virtual platform information also will be available

SUPPLEMENTARY INFORMATION: The Idaho National Laboratory (INL) Site,
near Arco, Idaho, currently stores solid calcined radioactive waste in
stainless-steel bins housed in six reinforced concrete vaults that are
below or partially below grade at the CSSF. The CSSF is located at the
Idaho Nuclear Technology and Engineering Center (INTEC) at the INL
Site. The stored calcined HLW was generated by converting liquid HLW
and non-reprocessing waste into a granular solid. The liquid HLW was
generated by the prior reprocessing of spent nuclear fuel (SNF). DOE's
current mission focuses on the cleanup and remediation of those wastes
and ultimate closure of the CSSF.
As part of that mission, DOE plans to retrieve waste from the CSSF
for treatment, and disposition out of the State of Idaho. Following
waste retrieval, DOE plans to stabilize in grout and pursue closure
(disposal in place) of the CSSF bins (including integral equipment),
transport lines, and any residual waste remaining therein.
The Draft CSSF 3116 Basis Document concerns the CSSF bins
(including integral equipment), transport lines, and any residual waste
remaining therein, after waste retrieval, which is anticipated to
remove most of the calcine, (approximately 99% or more of the calcine
(by volume) and approximately 99% of the radioactivity attributable to
highly radioactive radionuclides). A small amount of calcine, less than
approximately 1% by volume, is expected to remain in the CSSF at the
time of closure. The final CSSF closure configuration is anticipated to
include stabilizing (with grout) the bins and transport line piping
void spaces. The grout will serve to provide long term structural
stability, limit the amount of water infiltration into the bins and
transfer lines to mitigate contaminate migration, and provide a barrier
for intrusion by burrowing animals, plant roots, or humans.
NDAA Section 3116(a) provides that HLW does not include radioactive
waste resulting from the reprocessing of SNF that the Secretary of
Energy, in consultation with the NRC, determines:
``(1) does not require permanent isolation in a deep geologic
repository for spent fuel or high-level radioactive waste;
(2) has had highly radioactive radionuclides removed to the maximum
extent practical; and
(3) (A) does not exceed concentration limits for Class C low-level
waste as set out in Section 61.55 of title 10, Code of Federal
Regulations, and will be disposed of--
(i) in compliance with the performance objectives set out in
subpart C of part 61 of title 10, Code of Federal Regulations; and
(ii) pursuant to a State-approved closure plan or State-issued
permit, authority for the approval or issuance of which is conferred on
the State outside of this section; or
(B) exceeds concentration limits for Class C low-level waste as set
out in section 61.55 of title 10, Code of Federal Regulations, but will
be disposed of--
(i) in compliance with the performance objectives set out in
subpart C of part 61 of title 10, Code of Federal Regulations;
(ii) pursuant to a State-approved closure plan or State-issued
permit, authority for the approval or issuance of which is conferred on
the State outside of this section; and
(iii) pursuant to plans developed by the Secretary in consultation
with the Commission.''
The Draft CSSF 3116 Basis Document demonstrates that after waste
retrieval
[[Page 73833]]
activities, the CSSF at closure will meet the above criteria. DOE is
predicating this Draft CSSF 3116 Basis Document on extensive analysis
and scientific rationale, using a risk-informed approach, including
analyses presented in the Performance Assessment and Composite Analysis
for the INTEC Calcined Solids Storage Facility at the INL Site (CSSF
PA/CA).
Specifically, this Draft CSSF 3116 Basis Document shows that the
CSSF bins (including integral equipment), transport lines, and any
residual waste at the time of closure does not require permanent
isolation in a deep geologic repository for spent fuel or HLW, and that
the highly radioactive radionuclides (those radionuclides which
contribute most significantly to radiological dose to workers, the
public, and the environment as well as radionuclides listed in 10 CFR
61.55) will have been removed to the maximum extent practical. As also
shown in the Draft CSSF 3116 Basis Document, the stabilized (grouted)
CSSF stainless-steel bins (including integral equipment), transport
lines, and any residual waste at CSSF closure will not exceed
concentration limits for Class C LLW. Based on the analyses in the CSSF
PA/CA, this Draft CSSF 3116 Basis Document projects that potential
doses to a hypothetical member of the public and hypothetical
inadvertent intruder after CSSF closure will be well below the doses
specified in the performance objectives for disposal of LLW.
Furthermore, the CSSF closure will be performed pursuant to a State-
approved closure plan.
DOE is consulting with the NRC on this Draft CSSF 3116 Basis
Document and also making the Draft CSSF 3116 Basis Document available
for comments from states, Tribal Nations, stakeholders, and the public.
After consultation with the NRC, carefully considering comments
received, and performing any necessary revisions of analyses and
technical documents, DOE plans to issue a Final CSSF 3116 Basis
Document. Based on the Final CSSF 3116 Basis Document, the Secretary of
Energy, in consultation with the NRC, may determine in the future
whether the CSSF bins (including integral equipment), transport lines,
and any residual waste therein are non-HLW, and may be disposed in
place as LLW.
