SUPPLEMENTARY INFORMATION:
I. Introduction
The NRC is reviewing an exemption request from Susquehanna, dated
March 19, 2024, and supplemented on March 21, 2024. Susquehanna is requesting an
exemption, pursuant to section 72.7 of title 10 of the Code of Federal Regulations
(10 CFR), in paragraphs 72.212(a)(2), 72.212(b)(3), 72.212(b)(5)(i), 72.212(b)(11), and
72.214 that require Susquehanna to comply with the terms, conditions, and
2 specifications of the CoC No. 1032, Amendment No. 5. If approved, the exemption
would allow Susquehanna to load six new MPC-89-CBS in the HI-STORM FW MPC
Storage System at the SSES ISFSI in a storage condition where the terms, conditions,
and specifications in the CoC No. 1032, Amendment No. 5, are not met.
II. Environmental Assessment
=
Background===
SSES is located in Salem Township, Luzerne County, Pennsylvania, just west of
the Susquehanna River. The largest community within 10 miles (16 km) of the site is the
borough of Berwick, which is approximately 5 miles (8 km) southwest of SSES, in
Luzerne County, Pennsylvania. The nearest major metropolitan areas are Wilkes-Barre,
Pennsylvania, approximately 20 mi (32 km) to the northeast, and Allentown,
Pennsylvania, approximately 50 mi (80 km) to the southeast. Unit 1 began operating in
1981 and Unit 2 began operating in 1982. Susquehanna has been storing spent fuel in
an ISFSI at SSES under a general license as authorized by 10 CFR p art 72, subpart K,
General License for Storage of Spent Fuel at Power Reactor Sites. Susquehanna
currently uses the HI-STORM FW MPC Storage System under CoC No. 1032,
Amendment No. 5, for dry storage of spent nuclear fuel at the SSES ISFSI.
Description of the Proposed Action
The CoC is the NRC approved design for each dry cask storage system. The
proposed action would exempt the applicant from the requirements of
10 CFR 72.212(a)(2), 72.212(b)(3), 72.212(b)(5)(i), 72.212(b)(11), and 72.214 only as
these requirements pertain to the use of the MPC CBS in the HI-STORM FW MPC
Storage System for the near-term planned loading of the canisters. The exemption
would allow SSES to load six new MPC-89-CBS in the HI-STORM FW MPC Storage
System at the SSES ISFSI, despite the MPC CBS in the HI-STORM FW MPC
3 Storage System not being in compliance with the terms, conditions, and specifications in
CoC No. 1032, Amendment No. 5.
The HI-STORM FW MPC Storage System CoC provides the requirements,
conditions, and operating limits necessary for use of the system to store spent fuel.
Holtec International (Holtec), the designer and manufacturer of the HI-STORM FW MPC
Storage System, developed a variant of the design with CBS for the MPC-89, known as
MPC CBS. Holtec originally implemented the CBS variant design under the
provisions of 10 CFR 72.48, which allows licensees to make changes to cask designs
without a CoC amendment under certain conditions (listed in 10 CFR 72.48(c)). After
evaluating the specific changes to the cask designs, the NRC determined that Holtec
erred when it implemented the CBS variant design under 10 CFR 72.48, as this was not
the type of change allowed without a CoC amendment. For this reason, the NRC issued
three Severity Level IV violations to Holtec. Susquehanna plans to load six new MPC-
89-CBS in the HI-STORM FW MPC Storage System beginning in August 2024. This
exemption considers the near-term planned loading of the six canisters with the CBS
variant basket design.
Need For The Proposed Action
Susquehanna requested this exemption to allow SSES to load six new MPC CBS in the HI-STORM FW MPC Storage System at the SSES ISFSI for the future
loading campaign scheduled to begin in August 2024.
Approval of the exemption request would allow Susquehanna to effectively
manage the margin for full core reserve in the SSES spent fuel pool to enable refueling
and offloading fuel from the reactor. It would also allow Susquehanna to manage
logistical considerations, such as personnel and specific equipment resources, needed
to support refueling outages at SSES and across the industry.
4 Environmental Impacts of the Proposed Action
This EA evaluates the potential environmental impacts of granting an exemption
from the terms, conditions, and specifications in CoC No. 1032, Amendment No. 5. The
exemption would allow six new MPC CBS to be loaded in the HI-STORM FW MPC
Storage System in a near-term loading campaign beginning in August 2024 and
maintained in storage at the SSES ISFSI.
The potential environmental impacts of storing spent nuclear fuel in NRC-
approved storage systems have been documented in previous assessments. On
July 18, 1990 (55 FR 29181), the NRC amended 10 CFR part 72 to provide for the
storage of spent fuel under a general license in cask designs approved by the NRC. The
EA for the 1990 final rule analyzed the potential environmental impacts of using NRC-
approved storage casks. The EA for the HI -STORM FW MPC Storage System, CoC No.
1032, Amendment No. 5, (85 FR 28479), published in 2015, tiers off of the EA issued for
the July 18, 1990, final rule. Tiering off earlier EAs is a standard process encouraged
by the regulations implementing the National Environmental Policy Act of 1969 (NEPA)
that entails the use of impact analyses of previous EAs to bound the impacts of a
proposed action where appropriate. The Holtec HI-STORM FW MPC Storage System is
designed to mitigate the effects of design basis accidents that could occur during
storage. Considering the specific design requirements for the accident conditions, the
design of the cask would prevent loss of containment, shielding, and criticality control. If
there is no loss of containment, shielding, or criticality control, the environmental impacts
would not be significant.
The exemptions requested by Susquehanna at the SSES site as they relate to
CoC No. 1032, Amendment No. 5, for the HI-STORM FW MPC Storage System are
limited to the use of the CBS variant basket design only for the near-term planned
5 loading of six new canisters utilizing the CBS variant basket design. The staff has
determined that this change in the basket would not result in either radiological or non-
radiological environmental impacts that significantly differ from the environmental
impacts evaluated in the environmental assessment supporting the issuance of CoC No.
1032, Amendment No. 5. If the exemption is granted, there would be no significant
change in the types or amounts of any effluents released, no significant increase in
individual or cumulative public or occupational radiation exposure, and no significant
increase in the potential for or consequences from radiological accidents. Accordingly,
the Commission concludes that there would be no significant environmental impacts
associated with the proposed action.
Alternative to the Proposed Action
The staff considered the no-action alternative. The no -action alternative (denial of
the exemption request) would require Susquehanna to keep the spent fuel in the spent
fuel pool until older design canisters can be fabricated and delivered to site. Not allowing
the planned future loading campaign could affect Susquehannas ability to manage pool
capacity, reactor fuel offloading, and refueling. It could also impact Susquehannas
availability to manage personnel resources and coordinate refueling outages at SSES
and across the industry. The NRC has determined that these potential impacts of the no-
action alternative could be avoided by proceeding with the proposed exemption,
especially given that the staff has concluded in NRCs Safety Determination
Memorandum, issued with respect to the enforcement action against Holtec regarding
these violations, that fuel can be stored safety in the MPC CBS.
Agencies Consulted
The NRC provided the Pennsylvania Department of Environmental Protection
(PDEP) a copy of this draft EA for review by an email dated April 10, 2024. On April 12,
6 2024, the PDEP provided its concurrence by email.
III. Finding of No Significant Impact
The environmental impacts of the proposed action have been reviewed in
accordance with the requirements in 10 CFR part 51, which implement NEPA. Based
upon the foregoing e nvironmental assessment, the NRC finds that the proposed action
of granting the exemption from the regulations in 10 CFR 72.212(a)(2), 72.212(b)(3),
72.212(b)(5)(i), 72.212(b)(11) and 72.214, which require the licensee to comply with the
terms, conditions, and specifications of the CoC, would not significantly impact the
quality of the human environment. The exemption in this case would be limited to
specific future loading of six canisters with the CBS variant design beginning in August
2024. Accordingly, the NRC has determined that a FONSI is appropriate, and an
environmental impact statement is not warranted.
