SUPPLEMENTARY INFORMATION:

I. Introduction

    The NRC is reviewing an exemption request from CEG, dated January 
24, 2025, and supplemented on February 4, 2025. CEG 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 CEG to comply 
with the terms, conditions, and specifications of the CoC No. 1032, 
Amendment No. 1, Revision No. 1. If approved, the exemption would allow 
CEG to use the HI-STORM Flood/Wind (FW) MPC Storage System, including 
the use of the HI-TRAC during loading and transport operations, for 
seven specific MPCs (i.e., MPC-89) at the PB ISFSI, beginning in June 
2025, where the terms, conditions, and specifications in CoC No. 1032, 
Amendment No. 1, Revision No. 1, are not met.

II. Environmental Assessment

Background

    PB is located near Delta, Pennsylvania, in York County, 
approximately 38 miles (61 kilometers) north of Baltimore, Maryland. 
Both Units 2 and 3 began operating in 1974. CEG has been storing spent 
fuel in the PB ISFSI under a general license as authorized by 10 CFR 
part 72, subpart K, ``General License for Storage of Spent Fuel at 
Power Reactor Sites.'' CEG currently uses the HI-STORM FW MPC Storage 
System under CoC No. 1032, Amendment No. 1, Revision No. 1, for dry 
storage of spent nuclear fuel in a specific MPC (i.e., MPC-89) at the 
PB 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 seven MPC-89 in the HI-STORM FW MPC Storage System planned for a 
near-term loading campaign beginning in June 2025. The exemption would 
allow CEG to use the HI-STORM FW MPC Storage System, including the use 
of the HI-TRAC during loading and transport operations, for seven MPC-
89 at the PB ISFSI, beginning in June 2025, despite CEG's site-specific 
analysis of a postulated tornado missile event for the HI-TRAC not 
being in compliance with the terms, conditions, and specifications in 
the CoC No. 1032, Amendment No. 1, Revision No. 1.
    Before using a CoC, general licensees are required to perform a 
site-specific evaluation to establish that, once loaded with spent 
fuel, the cask will conform to the terms, conditions, and 
specifications of the CoC, including following the NRC-approved final 
safety analysis report (FSAR) methodology. CEG currently uses the HI-
STORM FW MPC Storage System under CoC No. 1032, Amendment No. 1, 
Revision No. 1, for dry storage of spent nuclear fuel in MPC-89 at the 
PB ISFSI. 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. One of the operating limits established in 
the CoC involves potential tornado-generated missile impacts. The HI-
STORM FW FSAR table 2.2.5 evaluates a generic set of tornado-generated 
missile impacts. CEG discovered that PB's site-specific analysis 
performed to demonstrate protection of the loaded MPC-89, while in the 
HI-TRAC, against tornado-generated missiles was not performed 
consistent with the NRC-approved method of evaluation in the FSAR. 
Contrary to CEG's site-specific analysis, the NRC-approved evaluation 
in the FSAR does not take credit for the missile resistance offered by 
the HI-TRAC water jacket shell, and assumes that the small and 
intermediate missiles will penetrate the water jacket shell with no 
energy loss.
    Therefore, CEG requests this exemption to allow it to conduct the 
planned loading and transport operations of the seven MPC-89 in the HI-
STORM FW MPC Storage System at PB ISFSI beginning in June 2025, even 
though, because of the different tornado-generated missile analysis of 
the HI-TRAC in PB's site specific review, the terms, conditions, and 
specifications of the CoC will not be met.

Need for the Proposed Action

    CEG requested this exemption in order to allow the use of the HI-
STORM FW MPC Storage System, including the use of the HI-TRAC during 
loading and transport operations for seven MPC-89 at the PB ISFSI, 
beginning in June 2025, despite the terms, conditions, and 
specifications of the CoC not being met. Approval of the exemption 
request would allow CEG to effectively manage the margin to full core 
discharge capacity to enable refueling and offloading fuel from the 
reactor. It would also allow CEG to effectively manage the availability 
of the specialized resources and equipment needed to support competing 
fuel loading and operational activities at PB.

Environmental Impacts of the Proposed Action

    This EA evaluates the potential environmental impacts of granting 
an

[[Page 11442]]

exemption from the terms, conditions, and specifications in CoC No. 
1032, Amendment No. 1, Revision No. 1. The exemption would allow CEG to 
use the HI-STORM FW MPC Storage System, including the use of the HI-
TRAC during loading and transport operations for seven MPC-89 at the PB 
ISFSI, for the loading campaign beginning in June 2025, even though the 
terms, conditions, and specifications of the CoC will not be met.
    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. 1, Revision No. 1 (80 FR 14291), 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 CEG at the PB site as they relate to 
CoC No. 1032, Amendment No. 1, Revision No. 1, for the HI-STORM FW MPC 
Storage System are limited to using the HI-TRAC during loading and 
transport operations for the MPC-89 for the planned loading of seven 
canisters starting in June 2025, despite the PB site-specific analysis 
of tornado-generated missiles not being performed consistent with the 
NRC-approved method of evaluation in the CoC FSAR, and so the terms, 
conditions, and specifications of the CoC not being met. The staff has 
determined that this change in analysis will not result in either 
radiological or non-radiological environmental impacts that 
significantly differ from the environmental impacts evaluated in the EA 
supporting the issuance of CoC No. 1032, Amendment No. 1, Revision No. 
1. If the exemption is granted, there will 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 CEG to 
delay the near-term planned loading of spent fuel in the MPC-89 in the 
HI-STORM FW MPC Storage System at the PB ISFSI. Delaying the loading of 
spent fuel in the seven casks in June 2025 could affect CEG's ability 
to effectively manage spent fuel pool capacity, reactor fuel 
offloading, and refueling. Not allowing the planned future loading 
campaign could also pose challenges to spent fuel heat removal and 
impact the availability of the specialized workforce and equipment 
needed to support competing fuel loading and operational activities at 
PB and other CEG sites.
    The NRC determined that the no-action alternative would result in 
undue potential human health and safety impacts that could be avoided 
by proceeding with the proposed exemption.

Agencies Consulted

    The NRC provided the Pennsylvania Bureau of Radiation Protection 
(PBRP), Division of Nuclear Safety, a copy of this draft EA for review 
by an email dated February 25, 2025. On February 26, 2025, PBRP 
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 EA, 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, in this case limited to the use of the 
Holtec HI-STORM FW MPC Storage System, including the use of the HI-TRAC 
during loading and transport operations, for the specific near-term 
future loading of seven MPC-89 beginning in June 2025, would not 
significantly impact the quality of the human environment. Accordingly, 
the NRC has determined that a FONSI is appropriate, and an 
environmental impact statement is not warranted.
