In 2003, the NRC issued Amendment No. 52 to IP1s provisional operating license, which changed the expiration date of the provisional license to be consistent with that of the Indian Point Nuclear Generating Unit No. 2 (IP2) facility license at that time. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) Section 50.82(a)(2), the IP1 license no longer authorizes operation of the reactor or emplacement or retention of fuel into the reactor vessel. There is no IP1 spent fuel in wet storage at the Indian Point Energy Center (IPEC) site; IP1 spent fuel is stored onsite in dry cask storage at the independent spent fuel storage installation (ISFSI).
{{#Wiki_filter:NUCLEAR REGULATORY COMMISSION
By {{letter dated|date=February 8, 2017|text=letter dated February 8, 2017}} (Agencywide Documents Access and Management System Accession No. ML17044A004), Entergy Nuclear Indian Point 2, LLC, and Entergy Nuclear Indian Point 3, LLC (the IPEC licensees at that time, collectively, Entergy) certified to the NRC that they planned to permanently cease power operations at IP2 and Indian Point Nuclear Generating Unit No. 3 (IP3) by April 30, 2020, and April 30, 2021, respectively. By letters dated May 12, 2020, and May 11, 2021 (ML20133J902 and ML21131A157), Entergy certified to the NRC that power operations permanently ceased at IP2 and IP3 on April 30, 1


2020, and April 30, 2021, respectively. In the same letters, Entergy certified to the NRC that the fuel was permanently removed from the IP2 and IP3 reactor vessels and placed in the IP2 and IP3 spent fuel pools (SFPs) as of May 12, 2020, and May 11, 2021, respectively.
Docket Nos. 50-003, 50-247, and 50-286
Based on the docketing of these certifications for permanent cessation of operations and permanent removal of fuel from the reactor vessels, as specified in 10 CFR 50.82(a)(2), the 10 CFR Part 50 renewed facility licenses for IP2 and IP3 (Nos. DPR-26 and DPR-64, respectively) no longer authorize operation of the reactors or emplacement or retention of fuel in the reactor vessels. The facility is still authorized to possess and store irradiated (i.e., spent) nuclear fuel. At the time of the exemption request described below, spent fuel was stored onsite at the IP2 and IP3 facilities in the SFPs and in a dry cask ISFSI.
II.      Request/Action By {{letter dated|date=March 18, 2022|text=letter dated March 18, 2022}} (ML22077A132), Holtec Decommissioning International, LLC (HDI), one of the licensees of IPEC and an indirect wholly owned subsidiary of Holtec International (Holtec), requested an exemption on behalf of Holtec Indian Point 2, LLC (a licensee of IP1 and IP2, referred to as Holtec IP2) and Holtec Indian Point 3, LLC (a licensee of IP3, and referred to as Holtec IP3), from the requirements of 10 CFR 50.54(w)(1) concerning onsite liability insurance. HDI, Holtec IP2, and Holtec IP3 are hereafter collectively referred to as the licensee. The exemption from 10 CFR 50.54(w)(1) would permit the licensee to reduce the required level of onsite property damage insurance from $1.06 billion to $50 million for IPEC.
The regulation at 10 CFR 50.54(w)(1) requires licensees to have and maintain onsite property damage insurance to stabilize and decontaminate the reactor(s) and reactor site in the event of an accident. The onsite insurance coverage must be either $1.06 billion or whatever amount of insurance is generally available from private sources (whichever is less).
The licensee states that the risk of an incident at a permanently shutdown and defueled reactor is much less than the risk from an operating power reactor. In addition, since reactor operation is no longer authorized at IPEC, there are no events that would require the 2


stabilization of reactor conditions after an accident. Similarly, the risk of an accident that would result in significant onsite contamination at IPEC is also much lower than the risk of such an event at operating reactors. Therefore, the licensee requested an exemption from 10 CFR 50.54(w)(1) to reduce its onsite property damage insurance from $1.06 billion to
Holtec Decommissioning International, LLC,
$50 million, commensurate with the reduced risk of an incident at the permanently shutdown and defueled IPEC site.
III. Discussion Under 10 CFR 50.12, Specific exemptions, the Commission may, upon application by any interested person or upon its own initiative, grant exemptions from the requirements of 10 CFR Part 50 when (1) the exemptions are authorized by law, will not present an undue risk to public health or safety, and are consistent with the common defense and security; and (2) any of the special circumstances listed in 10 CFR 50.12(a)(2) are present.
The financial protection limits of 10 CFR 50.54(w)(1) were established after the Three Mile Island Nuclear Station, Unit 2 accident out of concern that licensees may be unable to financially cover onsite cleanup costs in the event of a major nuclear accident. The specified
$1.06 billion coverage amount requirement was developed based on an analysis of an accident at a nuclear reactor operating at power, resulting in a large fission product release and requiring significant resource expenditures to stabilize the reactor and ultimately decontaminate and cleanup the site.
These cost estimates were developed based on the spectrum of postulated accidents for an operating nuclear reactor. Those costs were derived from the consequences of a release of radioactive material from the reactor. Although the risk of an accident at an operating reactor is very low, the consequences onsite and offsite can be significant. In an operating plant, the high temperature and pressure of the reactor coolant system (RCS), as well as the inventory of relatively short-lived radionuclides, contribute to both the risk and consequences of an accident.
With the permanent cessation of reactor operations at IPEC and the permanent removal of the 3


fuel from the reactor vessels, such accidents are no longer possible. As a result, the reactor vessels, RCS, and supporting systems no longer operate and have no function related to the storage of the irradiated fuel. Therefore, postulated accidents involving failure or malfunction of the reactors, RCS, or supporting systems are no longer applicable.
Holtec Indian Point 2, LLC, and Holtec Indian Point 3, LLC
During reactor decommissioning, the largest radiological risks are associated with the storage of spent fuel onsite. In the exemption request dated March 18, 2022, the licensee discussed both design-basis and beyond design-basis events involving irradiated fuel stored in the SFPs. The licensee determined that there are no possible design-basis events at IPEC that could result in an offsite radiological release exceeding the limits established by the U.S. Environmental Protection Agencys (EPA) early phase Protective Action Guides (PAGs) of 1 roentgen equivalent man (rem) at the exclusion area boundary, as a way to demonstrate that any possible radiological releases would be minimal and would not require precautionary protective actions (e.g., sheltering in place or evacuation). The NRC staff evaluated the radiological consequences associated with various decommissioning activities and the design basis accidents at IPEC, in consideration of the permanently shutdown and defueled condition.
The possible design-basis accident scenarios at IPEC have greatly reduced radiological consequences. Based on its review, the NRC staff concluded that no reasonably conceivable design-basis accident exists that could cause an offsite release greater than the EPA PAGs.
The only incident that has the potential to lead to a significant radiological release at a decommissioning reactor is a zirconium fire in the SFP. The zirconium fire scenario is a postulated, but highly unlikely, beyond design-basis accident scenario that involves loss of water inventory from the SFP resulting in a significant heat up of the spent fuel, and culminating in substantial zirconium cladding oxidation and fuel damage. The probability of a zirconium fire scenario is related to the decay heat of the irradiated fuel stored in the SFP. Therefore, the risks from a zirconium fire scenario continue to decrease as a function of the time since IPEC has been permanently shut down.

The Commission has previously authorized a lesser amount of onsite financial protection, based on this analysis of the zirconium fire risk. In SECY-96-256, Changes to Financial Protection Requirements for Permanently Shutdown Nuclear Power Reactors, 10 CFR 50.54(w) and 10 CFR 140.11, dated December 17, 1996 (ML15062A483), the NRC staff recommended changes to the power reactor financial protection regulations that would allow licensees to lower onsite insurance levels to $50 million upon demonstration that the fuel stored in the SFP can be air-cooled. In its Staff Requirements Memorandum to SECY-96-256, dated January 28, 1997 (ML15062A454), the Commission supported the NRC staffs recommendation that, among other things, would allow permanently shutdown power reactor licensees to reduce commercial onsite property damage insurance coverage to $50 million when the licensee was able to demonstrate the technical criterion that the spent fuel could be air-cooled if the SFP was drained of water.
Indian Point Nuclear Generating Unit Nos. 1, 2, and 3
The NRC staff has used this technical criterion to grant similar exemptions to other decommissioning reactors (e.g., Maine Yankee Atomic Power Station, published in the Federal Register (FR) on January 19, 1999 (64 FR 2920); Zion Nuclear Power Station, published in the FR on December 28, 1999 (64 FR 72700); Kewaunee Power Station, published in the FR on March 24, 2015 (80 FR 15638); Crystal River Unit 3 Nuclear Generation Plant, published in the FR on May 6, 2015 (80 FR 26100); Oyster Creek Nuclear Generating Station, published in the FR on December 28, 2018 (83 FR 67365); Pilgrim Nuclear Power Station, published in the FR on January 14, 2020 (85 FR 2153); Three Mile Island Nuclear Station, Unit 1, published in the FR on March 26, 2021 (86 FR 16241); and the Duane Arnold Energy Center, published in the FR on May 18, 2021 (86 FR 26946)). These prior exemptions were based on these licensees demonstrating that the SFP could be air-cooled, consistent with the technical criterion discussed above.
In its March 18, 2022, request, the licensee compared the IPEC fuel storage parameters with those used in NRC generic evaluations of fuel cooling included in NUREG/CR-6451, A 5


Safety and Regulatory Assessment of Generic BWR [Boiling-Water Reactor] and PWR
Exemption
[Pressurized-Water Reactor] Permanently Shutdown Nuclear Power Plants, dated August 1997 (ML082260098). The analysis described in NUREG/CR-6451 determined that natural air circulation would adequately cool fuel in the representative PWR.
In SECY-00-0145, Integrated Rulemaking Plan for Nuclear Power Plant Decommissioning, dated June 28, 2000, and SECY-01-0100, Policy Issues Related to Safeguards, Insurance, and Emergency Preparedness Regulations at Decommissioning Nuclear Power Plants Storing Fuel in Spent Fuel Pools, dated June 4, 2001 (ML003721626 and ML011450420, respectively), the NRC staff discussed additional information concerning SFP zirconium fire risks at decommissioning reactors and associated implications for onsite property damage insurance. Providing an analysis of when the spent fuel stored in the SFP is capable of air-cooling is one measure that can be used to demonstrate that the probability of a zirconium fire is exceedingly low.
In their {{letter dated|date=March 18, 2022|text=letter dated March 18, 2022}}, HDI stated, and the NRC staff confirmed, that the bounding analyses for the IP2 and IP3 SFPs for beyond design basis events demonstrate that 15 months after shutdown of IP3 a minimum of 10 hours is available before the fuel cladding temperature of the hottest fuel assembly in either SFP reaches 900°C with a complete loss of SFP water inventory. This analysis, Holtec Spent Fuel Pool Heat Up Calculation Methodology Topical Report, Revision 2, dated December 22, 2021 (ML21357A005 [non-public]), was submitted by HDI in support of a request for exemptions from certain emergency planning requirements, dated December 22, 2021 (ML21356B693). HDI provided further information in , Indian Point Unit Nos. 2 and 3 Spent Fuel Pool Heat Up Calculations, to HDIs supplemental {{letter dated|date=February 1, 2022|text=letter dated February 1, 2022}} (ML22032A117).
As stated in NUREG-1738, Technical Study of Spent Fuel Pool Accident Risk at Decommissioning Nuclear Power Plants, dated February 2001 (ML010430066), 900°C is an acceptable temperature to use for assessing the onset of fission product release, where the 6


SFP is drained and air cooling is not possible; at least 10 hours would be available from the time spent fuel cooling is lost until the hottest fuel assembly reaches a temperature of 900°C. The 10-hour criterion, conservatively, does not consider the time to uncover the fuel and assumes instantaneous loss of cooling to the fuel. The 10-hour time period is also not intended to represent the time that it would take to repair all key safety systems or to repair a large SFP breach. The 10-hour criterion is a conservative period of time in which pre-planned mitigation measures to provide makeup water or spray to the SFP can be reliably implemented before the onset of a zirconium cladding ignition. In addition, in the unlikely event that a release is projected to occur, 10 hours would provide sufficient time for offsite agencies, if deemed warranted, to take appropriate action to protect the health and safety of the public.
I. Background
In the NRC staffs evaluation contained in SECY-22-0102, the NRC staff assessed the HDI accident analyses associated with the radiological risks from a zirconium fire at a permanently shutdown and defueled IPEC after 15 months of fuel decay. For the highly unlikely beyond design-basis accident scenario where the SFP coolant inventory is lost in such a manner that all methods of heat removal from the spent fuel are no longer available, the NRC staff found that there will be a minimum of 10 hours from the initiation of the accident until the cladding reaches a temperature where offsite radiological release might occur. The NRC staff finds that 10 hours is sufficient time to support deployment of mitigation equipment, consistent with plant conditions, to prevent the zirconium cladding from reaching a point of rapid oxidation.
As a result, the likelihood that such a scenario would progress to a zirconium fire is deemed not credible.
Based on the evaluation in SECY-96-256, as well as analysis done by HDI and verified by the NRC staff, the NRC staff determined $50 million to be an adequate level of onsite property damage insurance for a decommissioning reactor once the spent fuel in the SFP is no longer susceptible to a zirconium fire. However, the NRC staff has postulated that there is still a potential for other radiological incidents at a decommissioning reactor that could result in 7


significant onsite contamination besides a zirconium fire. In SECY-96-256, the NRC staff cited the rupture of a large, contaminated liquid storage tank (~450,000 gallons) causing soil contamination and potential groundwater contamination as the costliest postulated event to decontaminate and remediate (other than an SFP zirconium fire). The postulated large liquid radiological waste storage tank rupture event was determined to have a bounding onsite cleanup cost of approximately $50 million. Therefore, the NRC staff determined that the licensees proposal to reduce onsite insurance to a level of $50 million would be consistent with the bounding cleanup and decontamination cost, as discussed in SECY-96-256, to account for the postulated rupture of a large liquid radiological waste tank at the IPEC site, should such an event occur.
Indian Point Nuclear Generating Unit No. 1 (IP1) permanently ceased generation on
The NRC staff has determined that the licensees proposed reduction in onsite property damage insurance coverage to a level of $50 million is consistent with SECY-96-256 and subsequent insurance considerations resulting from additional zirconium fire risks as discussed in SECY-00-0145 and SECY-01-0100, as well as NUREG/CR-6451 and NUREG-1738. In addition, the NRC staff notes that similar exemptions have been granted to other permanently shutdown and defueled power reactors, upon demonstration that the criterion of the zirconium fire risks from the irradiated fuel stored in the SFP is of negligible concern. The NRC staff concluded that 15 months after the permanent shutdown date of IP3 of April 30, 2021, sufficient irradiated fuel decay time will have elapsed at IPEC to decrease the probability of an onsite radiological release from a postulated zirconium fire accident to negligible levels. In addition, the licensees proposal to reduce onsite insurance to a level of $50 million is consistent with the maximum estimated cleanup costs for the recovery from the rupture of a large liquid radwaste storage tank.
The NRC staff also notes that in accordance with letters submitted by HDI on February 15, 2023, and October 16, 2023 (ML23046A102 and ML23289A158), all the spent fuel from the 8


IP2 and IP3 SFPs has been transferred to dry storage within the ISFSI. As such, an initiating event that would threaten SFP integrity is no longer applicable.
October 31, 1974, and all fuel was removed from the IP1 reactor vessel by January 1976. In
A.      The Exemption is Authorized by Law The requested exemption from 10 CFR 50.54(w)(1) would allow the licensee to reduce the minimum coverage limit for onsite property damage insurance. As stated above, 10 CFR 50.12 allows the NRC to grant exemptions from the requirements of 10 CFR Part 50 when the exemptions are authorized by law.
As explained above, the NRC staff has determined that the licensees proposed reduction in onsite property damage insurance coverage to a level of $50 million is consistent with SECY-96-256. Moreover, the NRC staff concluded that 15 months after the permanent cessation of power operations, sufficient irradiated fuel decay time will have elapsed at IPEC to decrease the probability of an onsite and offsite radiological release from a postulated zirconium fire accident to negligible levels. In addition, the licensees proposal to reduce onsite insurance to a level of $50 million is consistent with the maximum estimated cleanup costs for the recovery from the rupture of a large liquid radiological waste storage tank.
The NRC staff has determined that granting the licensees proposed exemption will not result in a violation of the Atomic Energy Act of 1954, as amended, or the Commissions regulations. Therefore, based on its review of the licensees exemption request as discussed above, and consistent with SECY-96-256, the NRC staff concludes that the exemption is authorized by law.
B.      The Exemption Presents No Undue Risk to the Public Health and Safety The onsite property damage insurance requirements of 10 CFR 50.54(w)(1) were established to provide financial assurance that following a significant nuclear incident, onsite conditions could be stabilized and the site decontaminated. The requirements of 10 CFR 50.54(w)(1) and the existing level of onsite insurance coverage for IPEC are predicated on the assumption that the reactor is operating. However, IPEC permanently ceased power 9


operations on October 31, 1974, April 30, 2020, and April 30, 2021 (For IP1, IP2, and IP3, respectively), and permanently defueled as of January 1976, May 12, 2020, and May 11, 2021 (For IP1, IP2, and IP3, respectively). The permanent cessation of operations and defueled status of the facility results in a significant reduction in the number and severity of potential accidents and, correspondingly, a significant reduction in the potential for and severity of onsite property damage. The proposed reduction in the amount of onsite insurance coverage does not impact the probability or consequences of potential accidents. The proposed level of insurance coverage is commensurate with the reduced consequences of potential nuclear accidents at IPEC. Therefore, the NRC staff concludes that granting the requested exemption will not present an undue risk to the health and safety of the public.
1996, the U.S. Nuclear Regulatory Commission (NRC, the Commission) issued an order
C.      The Exemption Is Consistent with the Common Defense and Security The proposed exemption would not eliminate any requirements associated with physical protection of the site and would not adversely affect the licensees ability to physically secure the site or protect special nuclear material. Physical security measures at IPEC are not affected by the requested exemption. Therefore, the proposed exemption is consistent with the common defense and security.
D.      Special Circumstances Special circumstances, in accordance with 10 CFR 50.12(a)(2)(ii), are present whenever application of the regulation in the particular circumstances is not necessary to achieve the underlying purpose of the regulation.
The underlying purpose of 10 CFR 50.54(w)(1) is to provide reasonable assurance that adequate funds will be available to stabilize reactor conditions and cover onsite cleanup costs associated with site decontamination following an accident that results in the release of a significant amount of radiological material. Since IPEC permanently ceased power operations on October 31, 1974, April 30, 2020, and April 30, 2021 (For IP1, IP2, and IP3, respectively),
and permanently defueled as of January 1976, May 12, 2020, and May 11, 2021 (For IP1, IP2, 10


and IP3, respectively), it is no longer possible for the radiological consequences of design-basis accidents or other credible events at IPEC to exceed the limits of the EPA PAGs at the exclusion area boundary. The licensee has evaluated the consequences of highly unlikely, beyond-design-basis conditions involving a loss of coolant from the SFP. The analyses show that 15 months after the permanent cessation of power operations, the likelihood of such an event leading to a large radiological release is negligible. The NRC staffs evaluation of the licensees analyses confirms this conclusion.
approving the safe-storage condition of IP1. In 2003, the NRC issued Amendment No. 52 to
The NRC staff also finds that the licensees proposed $50 million level of onsite insurance is consistent with the bounding cleanup and decontamination cost as discussed in SECY-96-256, to account for the hypothetical rupture of a large liquid radiological waste tank at the IPEC site, should such an event occur. Therefore, the NRC staff concludes that the application of the current requirements in 10 CFR 50.54(w)(1) to maintain $1.06 billion in onsite insurance coverage is not necessary to achieve the underlying purpose of the rule for the permanently shutdown and defueled IPEC reactors.
Under 10 CFR 50.12(a)(2)(iii), special circumstances are present whenever compliance would result in undue hardship or other costs that are significantly in excess of those contemplated when the regulation was adopted, or that are significantly in excess of those incurred by others similarly situated.
The NRC staff concludes that if the licensee was required to continue to maintain an onsite insurance level of $1.06 billion, the associated insurance premiums would be in excess of those necessary and commensurate with the radiological contamination risks posed by the site.
In addition, such insurance levels would be significantly in excess of other decommissioning reactor facilities that have been granted similar exemptions by the NRC.
The NRC staff finds that compliance with the existing rule would result in an undue hardship or other costs that are significantly in excess of those contemplated when the 11


regulation was adopted and are significantly in excess of those incurred by others similarly situated.
IP1s provisional operating license, which changed the expiration date of the provisional license
Therefore, the special circumstances required by 10 CFR 50.12(a)(2)(ii) and 10 CFR 50.12(a)(2)(iii) exist.
E.        Environmental Considerations The NRCs approval of an exemption from insurance or indemnity requirements belongs to a category of actions that the Commission, by rule or regulation, has declared to be a categorical exclusion after first finding that the category of actions does not individually or cumulatively have a significant effect on the human environment. Specifically, the exemption is categorically excluded from the requirement to prepare an environmental assessment or environmental impact statement in accordance with 10 CFR 51.22(c)(25).
Under 10 CFR 51.22(c)(25), granting of an exemption from the requirements of any regulation of Chapter I to 10 CFR, Nuclear Regulatory Commission, is a categorical exclusion provided that: (i) there is no significant hazards consideration; (ii) there is no significant change in the types or significant increase in the amounts of any effluents that may be released offsite; (iii) there is no significant increase in individual or cumulative public or occupational radiation exposure; (iv) there is no significant construction impact; (v) there is no significant increase in the potential for or consequences from radiological accidents; and (vi) the requirements from which an exemption is sought involve surety, insurance, or indemnity requirements.
As the Director of the Division of Decommissioning, Uranium Recovery, and Waste Programs in the NRCs Office of Nuclear Material Safety and Safeguards, I have determined that approval of the exemption request involves no significant hazards consideration, as defined in 10 CFR 50.92, Issuance of amendment, because reducing the licensees onsite property damage insurance for IPEC does not: (1) involve a significant increase in the probability or consequences of an accident previously evaluated; (2) create the possibility of a new or different kind of accident from any accident previously evaluated; or (3) involve a significant 12


reduction in a margin of safety. The exempted financial protection regulation is unrelated to the operation of IPEC or site activities. Accordingly, there is no significant change in the types or significant increase in the amounts of any effluents that may be released offsite and no significant increase in individual or cumulative public or occupational radiation exposure. The exempted regulation is not associated with construction so there is no significant construction impact. The exempted regulation does not concern the source term (i.e., potential amount of radiation in an accident) or any activities conducted at the site. Therefore, there is no significant increase in the potential for, or consequences of, a radiological accident. In addition, there would be no significant impacts to biota, water resources, historic properties, cultural resources, or socioeconomic conditions in the region resulting from issuance of the requested exemption.
to be consistent with that of the Indian Point Nuclear Generating Unit No. 2 (IP2) facility license
The requirement for onsite property damage insurance involves surety, insurance, and indemnity matters only.
Therefore, pursuant to 10 CFR 51.22(b) and 51.22(c)(25), Criterion for categorical exclusion; identification of licensing and regulatory actions eligible for categorical exclusion or otherwise not requiring environmental review, no environmental impact statement or environmental assessment need be prepared in connection with the approval of this exemption request.
IV. Conclusions Accordingly, the Commission has determined that, pursuant to 10 CFR 50.12(a), the exemption is authorized by law, will not present an undue risk to the public health and safety, and is consistent with the common defense and security. Also, special circumstances are present as set forth in 10 CFR 50.12.
Therefore, the Commission hereby grants the licensee an exemption from the requirements of 10 CFR 50.54(w)(1) for IPEC. IPEC permanently ceased power operations on October 31, 1974, April 30, 2020, and April 30, 2021, for IP1, IP2, and IP3, respectively. The exemption from 10 CFR 50.54(w)(1) permits IPEC to reduce the minimum required onsite 13


property damage insurance from $1.06 billion to $50 million 15 months after permanent cessation of power operations, which was August 1, 2022. Because this period has already elapsed, the exemption is effective upon issuance.
at that time. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) Section
 
50.82(a)(2), the IP1 license no longer authorizes operation of the reactor or emplacement or
 
retention of fuel into the reactor vessel. There is no IP1 spent fuel in wet storage at the Indian
 
Point Energy Center (IPEC) site; IP1 spent fuel is stored onsite in dry cask storage at the
 
independent spent fuel storage installation (ISFSI).
 
By {{letter dated|date=February 8, 2017|text=letter dated February 8, 2017}} (Agencywide Documents Access and Management
 
System Accession No. ML17044A004), Entergy Nuclear Indian Point 2, LLC, and Entergy
 
Nuclear Indian Point 3, LLC (the IPEC licensees at that time, collectively, Entergy) certified to
 
the NRC that they planned to permanently cease power operations at IP2 and Indian Point
 
Nuclear Generating Unit No. 3 (IP3) by April 30, 2020, and April 30, 2021, respectively. By
 
letters dated May 12, 2020, and May 11, 2021 (ML20133J902 and ML21131A157), Entergy
 
certified to the NRC that power operations permanently ceased at IP2 and IP3 on April 30,
 
1 2020, and April 30, 2021, respectively. In the same letters, Entergy certified to the NRC that the
 
fuel was permanently removed from the IP2 and IP3 reactor vessels and placed in the IP2 and
 
IP3 spent fuel pools (SFPs) as of May 12, 2020, and May 11, 2021, respectively.
 
Based on the docketing of these certifications for permanent cessation of operations and
 
permanent removal of fuel from the reactor vessels, as specified in 10 CFR 50.82(a)(2), the
 
10 CFR Part 50 renewed facility licenses for IP2 and IP3 (Nos. DPR-26 and DPR-64,
 
respectively) no longer authorize operation of the reactors or emplacement or retention of fuel in
 
the reactor vessels. The facility is still authorized to possess and store irradiated (i.e., spent)
 
nuclear fuel. At the time of the exemption request described below, spent fuel was stored onsite
 
at the IP2 and IP3 facilities in the SFPs and in a dry cask ISFSI.
 
II. Request/Action
 
By {{letter dated|date=March 18, 2022|text=letter dated March 18, 2022}} (ML22077A132), Holtec Decommissioning International,
 
LLC (HDI), one of the licensees of IPEC and an indirect wholly owned subsidiary of Holtec
 
International (Holtec), requested an exemption on behalf of Holtec Indian Point 2, LLC (a
 
licensee of IP1 and IP2, referred to as Holtec IP2) and Holtec Indian Point 3, LLC (a licensee of
 
IP3, and referred to as Holtec IP3), from the requirements of 10 CFR 50.54(w)(1) concerning
 
onsite liability insurance. HDI, Holtec IP2, and Holtec IP3 are hereafter collectively referred to as
 
the licensee. The exemption from 10 CFR 50.54(w)(1) would permit the licensee to reduce the
 
required level of onsite property damage insurance from $1.06 billion to $50 million for IPEC.
 
The regulation at 10 CFR 50.54(w)(1) requires licensees to have and maintain onsite
 
property damage insurance to stabilize and decontaminate the reactor(s) and reactor site in the
 
event of an accident. The onsite insurance coverage must be either $1.06 billion or whatever
 
amount of insurance is generally available from private sources (whichever is less).
 
The licensee states that the risk of an incident at a permanently shutdown and defueled
 
reactor is much less than the risk from an operating power reactor. In addition, since reactor
 
operation is no longer authorized at IPEC, there are no events that would require the
 
2 stabilization of reactor conditions after an accident. Similarly, the risk of an accident that would
 
result in significant onsite contamination at IPEC is also much lower than the risk of such an
 
event at operating reactors. Therefore, the licensee requested an exemption from
 
10 CFR 50.54(w)(1) to reduce its onsite property damage insurance from $1.06 billion to
 
$50 million, commensurate with the reduced risk of an incident at the permanently shutdown
 
and defueled IPEC site.
 
III. Discussion
 
Under 10 CFR 50.12, Specific exemptions, the Commission may, upon application by
 
any interested person or upon its own initiative, grant exemptions from the requirements of
 
10 CFR Part 50 when (1) the exemptions are authorized by law, will not present an undue risk
 
to public health or safety, and are consistent with the common defense and security; and (2) any
 
of the special circumstances listed in 10 CFR 50.12(a)(2) are present.
 
The financial protection limits of 10 CFR 50.54(w)(1) were established after the Three
 
Mile Island Nuclear Station, Unit 2 accident out of concern that licensees may be unable to
 
financially cover onsite cleanup costs in the event of a major nuclear accident. The specified
 
$1.06 billion coverage amount requirement was developed based on an analysis of an accident
 
at a nuclear reactor operating at power, resulting in a large fission product release and requiring
 
significant resource expenditures to stabilize the reactor and ultimately decontaminate and
 
cleanup the site.
 
These cost estimates were developed based on the spectrum of postulated accidents for
 
an operating nuclear reactor. Those costs were derived from the consequences of a release of
 
radioactive material from the reactor. Although the risk of an accident at an operating reactor is
 
very low, the consequences onsite and offsite can be significant. In an operating plant, the high
 
temperature and pressure of the reactor coolant system (RCS), as well as the inventory of
 
relatively short-lived radionuclides, contribute to both the risk and consequences of an accident.
 
With the permanent cessation of reactor operations at IPEC and the permanent removal of the
 
3 fuel from the reactor vessels, such accidents are no longer possible. As a result, the reactor
 
vessels, RCS, and supporting systems no longer operate and have no function related to the
 
storage of the irradiated fuel. Therefore, postulated accidents involving failure or malfunction of
 
the reactors, RCS, or supporting systems are no longer applicable.
 
During reactor decommissioning, the largest radiological risks are associated with the
 
storage of spent fuel onsite. In the exemption request dated March 18, 2022, the licensee
 
discussed both design-basis and beyond design-basis events involving irradiated fuel stored in
 
the SFPs. The licensee determined that there are no possible design-basis events at IPEC that
 
could result in an offsite radiological release exceeding the limits established by the
 
U.S. Environmental Protection Agencys (EPA) early phase Protective Action Guides (PAGs) of
 
1 roentgen equivalent man (rem) at the exclusion area boundary, as a way to demonstrate that
 
any possible radiological releases would be minimal and would not require precautionary
 
protective actions (e.g., sheltering in place or evacuation). The NRC staff evaluated the
 
radiological consequences associated with various decommissioning activities and the design
 
basis accidents at IPEC, in consideration of the permanently shutdown and defueled condition.
 
The possible design-basis accident scenarios at IPEC have greatly reduced radiological
 
consequences. Based on its review, the NRC staff concluded that no reasonably conceivable
 
design-basis accident exists that could cause an offsite release greater than the EPA PAGs.
 
The only incident that has the potential to lead to a significant radiological release at a
 
decommissioning reactor is a zirconium fire in the SFP. The zirconium fire scenario is a
 
postulated, but highly unlikely, beyond design-basis accident scenario that involves loss of
 
water inventory from the SFP resulting in a significant heat up of the spent fuel, and culminating
 
in substantial zirconium cladding oxidation and fuel damage. The probability of a zirconium fire
 
scenario is related to the decay heat of the irradiated fuel stored in the SFP. Therefore, the risks
 
from a zirconium fire scenario continue to decrease as a function of the time since IPEC has
 
been permanently shut down.
 
4 The Commission has previously authorized a lesser amount of onsite financial
 
protection, based on this analysis of the zirconium fire risk. In SECY-96-256, Changes to
 
Financial Protection Requirements for Permanently Shutdown Nuclear Power Reactors,
 
10 CFR 50.54(w) and 10 CFR 140.11, dated December 17, 1996 (ML15062A483), the NRC
 
staff recommended changes to the power reactor financial protection regulations that would
 
allow licensees to lower onsite insurance levels to $50 million upon demonstration that the fuel
 
stored in the SFP can be air-cooled. In its Staff Requirements Memorandum to SECY-96-256,
 
dated January 28, 1997 (ML15062A454), the Commission supported the NRC staffs
 
recommendation that, among other things, would allow permanently shutdown power reactor
 
licensees to reduce commercial onsite property damage insurance coverage to $50 million
 
when the licensee was able to demonstrate the technical criterion that the spent fuel could be
 
air-cooled if the SFP was drained of water.
 
The NRC staff has used this technical criterion to grant similar exemptions to other
 
decommissioning reactors (e.g., Maine Yankee Atomic Power Station, published in the Federal
 
Register (FR) on January 19, 1999 (64 FR 2920); Zion Nuclear Power Station, published in the
 
FR on December 28, 1999 (64 FR 72700); Kewaunee Power Station, published in the FR on
 
March 24, 2015 (80 FR 15638); Crystal River Unit 3 Nuclear Generation Plant, published in the
 
FR on May 6, 2015 (80 FR 26100); Oyster Creek Nuclear Generating Station, published in the
 
FR on December 28, 2018 (83 FR 67365); Pilgrim Nuclear Power Station, published in the FR
 
on January 14, 2020 (85 FR 2153); Three Mile Island Nuclear Station, Unit 1, published in the
 
FR on March 26, 2021 (86 FR 16241); and the Duane Arnold Energy Center, published in the
 
FR on May 18, 2021 (86 FR 26946)). These prior exemptions were based on these licensees
 
demonstrating that the SFP could be air-cooled, consistent with the technical criterion discussed
 
above.
 
In its March 18, 2022, request, the licensee compared the IPEC fuel storage parameters
 
with those used in NRC generic evaluations of fuel cooling included in NUREG/CR-6451, A
 
5 Safety and Regulatory Assessment of Generic BWR [Boiling-Water Reactor] and PWR
 
[Pressurized-Water Reactor] Permanently Shutdown Nuclear Power Plants, dated August 1997
 
(ML082260098). The analysis described in NUREG/CR-6451 determined that natural air
 
circulation would adequately cool fuel in the representative PWR.
 
In SECY-00-0145, Integrated Rulemaking Plan for Nuclear Power Plant
 
Decommissioning, dated June 28, 2000, and SECY-01-0100, Policy Issues Related to
 
Safeguards, Insurance, and Emergency Preparedness Regulations at Decommissioning
 
Nuclear Power Plants Storing Fuel in Spent Fuel Pools, dated June 4, 2001 (ML003721626
 
and ML011450420, respectively), the NRC staff discussed additional information concerning
 
SFP zirconium fire risks at decommissioning reactors and associated implications for onsite
 
property damage insurance. Providing an analysis of when the spent fuel stored in the SFP is
 
capable of air-cooling is one measure that can be used to demonstrate that the probability of a
 
zirconium fire is exceedingly low.
 
In their {{letter dated|date=March 18, 2022|text=letter dated March 18, 2022}}, HDI stated, and the NRC staff confirmed, that the
 
bounding analyses for the IP2 and IP3 SFPs for beyond design basis events demonstrate that
 
15 months after shutdown of IP3 a minimum of 10 hours is available before the fuel cladding
 
temperature of the hottest fuel assembly in either SFP reaches 900°C with a complete loss of
 
SFP water inventory. This analysis, Holtec Spent Fuel Pool Heat Up Calculation Methodology
 
Topical Report, Revision 2, dated December 22, 2021 (ML21357A005 [non-public]), was
 
submitted by HDI in support of a request for exemptions from certain emergency planning
 
requirements, dated December 22, 2021 (ML21356B693). HDI provided further information in
, Indian Point Unit Nos. 2 and 3 Spent Fuel Pool Heat Up Calculations, to HDIs
 
supplemental {{letter dated|date=February 1, 2022|text=letter dated February 1, 2022}} (ML22032A117).
 
As stated in NUREG-1738, Technical Study of Spent Fuel Pool Accident Risk at
 
Decommissioning Nuclear Power Plants, dated February 2001 (ML010430066), 900°C is an
 
acceptable temperature to use for assessing the onset of fission product release, where the
 
6 SFP is drained and air cooling is not possible; at least 10 hours would be available from the time
 
spent fuel cooling is lost until the hottest fuel assembly reaches a temperature of 900°C. The
 
10-hour criterion, conservatively, does not consider the time to uncover the fuel and assumes
 
instantaneous loss of cooling to the fuel. The 10-hour time period is also not intended to
 
represent the time that it would take to repair all key safety systems or to repair a large SFP
 
breach. The 10-hour criterion is a conservative period of time in which pre-planned mitigation
 
measures to provide makeup water or spray to the SFP can be reliably implemented before the
 
onset of a zirconium cladding ignition. In addition, in the unlikely event that a release is
 
projected to occur, 10 hours would provide sufficient time for offsite agencies, if deemed
 
warranted, to take appropriate action to protect the health and safety of the public.
 
In the NRC staffs evaluation contained in SECY-22-0102, the NRC staff assessed the
 
HDI accident analyses associated with the radiological risks from a zirconium fire at a
 
permanently shutdown and defueled IPEC after 15 months of fuel decay. For the highly unlikely
 
beyond design-basis accident scenario where the SFP coolant inventory is lost in such a
 
manner that all methods of heat removal from the spent fuel are no longer available, the NRC
 
staff found that there will be a minimum of 10 hours from the initiation of the accident until the
 
cladding reaches a temperature where offsite radiological release might occur. The NRC staff
 
finds that 10 hours is sufficient time to support deployment of mitigation equipment, consistent
 
with plant conditions, to prevent the zirconium cladding from reaching a point of rapid oxidation.
 
As a result, the likelihood that such a scenario would progress to a zirconium fire is deemed not
 
credible.
 
Based on the evaluation in SECY-96-256, as well as analysis done by HDI and verified
 
by the NRC staff, the NRC staff determined $50 million to be an adequate level of onsite
 
property damage insurance for a decommissioning reactor once the spent fuel in the SFP is no
 
longer susceptible to a zirconium fire. However, the NRC staff has postulated that there is still a
 
potential for other radiological incidents at a decommissioning reactor that could result in
 
7 significant onsite contamination besides a zirconium fire. In SECY-96-256, the NRC staff cited
 
the rupture of a large, contaminated liquid storage tank (~450,000 gallons) causing soil
 
contamination and potential groundwater contamination as the costliest postulated event to
 
decontaminate and remediate (other than an SFP zirconium fire). The postulated large liquid
 
radiological waste storage tank rupture event was determined to have a bounding onsite
 
cleanup cost of approximately $50 million. Therefore, the NRC staff determined that the
 
licensees proposal to reduce onsite insurance to a level of $50 million would be consistent with
 
the bounding cleanup and decontamination cost, as discussed in SECY-96-256, to account for
 
the postulated rupture of a large liquid radiological waste tank at the IPEC site, should such an
 
event occur.
 
The NRC staff has determined that the licensees proposed reduction in onsite property
 
damage insurance coverage to a level of $50 million is consistent with SECY-96-256 and
 
subsequent insurance considerations resulting from additional zirconium fire risks as discussed
 
in SECY-00-0145 and SECY-01-0100, as well as NUREG/CR-6451 and NUREG-1738. In
 
addition, the NRC staff notes that similar exemptions have been granted to other permanently
 
shutdown and defueled power reactors, upon demonstration that the criterion of the zirconium
 
fire risks from the irradiated fuel stored in the SFP is of negligible concern. The NRC staff
 
concluded that 15 months after the permanent shutdown date of IP3 of April 30, 2021, sufficient
 
irradiated fuel decay time will have elapsed at IPEC to decrease the probability of an onsite
 
radiological release from a postulated zirconium fire accident to negligible levels. In addition, the
 
licensees proposal to reduce onsite insurance to a level of $50 million is consistent with the
 
maximum estimated cleanup costs for the recovery from the rupture of a large liquid radwaste
 
storage tank.
 
The NRC staff also notes that in accordance with letters submitted by HDI on February
 
15, 2023, and October 16, 2023 (ML23046A102 and ML23289A158), all the spent fuel from the
 
8 IP2 and IP3 SFPs has been transferred to dry storage within the ISFSI. As such, an initiating
 
event that would threaten SFP integrity is no longer applicable.
 
A. The Exemption is Authorized by Law
 
The requested exemption from 10 CFR 50.54(w)(1) would allow the licensee to reduce
 
the minimum coverage limit for onsite property damage insurance. As stated above, 10 CFR
 
50.12 allows the NRC to grant exemptions from the requirements of 10 CFR Part 50 when the
 
exemptions are authorized by law.
 
As explained above, the NRC staff has determined that the licensees proposed
 
reduction in onsite property damage insurance coverage to a level of $50 million is consistent
 
with SECY-96-256. Moreover, the NRC staff concluded that 15 months after the permanent
 
cessation of power operations, sufficient irradiated fuel decay time will have elapsed at IPEC to
 
decrease the probability of an onsite and offsite radiological release from a postulated zirconium
 
fire accident to negligible levels. In addition, the licensees proposal to reduce onsite insurance
 
to a level of $50 million is consistent with the maximum estimated cleanup costs for the recovery
 
from the rupture of a large liquid radiological waste storage tank.
 
The NRC staff has determined that granting the licensees proposed exemption will not
 
result in a violation of the Atomic Energy Act of 1954, as amended, or the Commissions
 
regulations. Therefore, based on its review of the licensees exemption request as discussed
 
above, and consistent with SECY-96-256, the NRC staff concludes that the exemption is
 
authorized by law.
 
B. The Exemption Presents No Undue Risk to the Public Health and Safety
 
The onsite property damage insurance requirements of 10 CFR 50.54(w)(1) were
 
established to provide financial assurance that following a significant nuclear incident, onsite
 
conditions could be stabilized and the site decontaminated. The requirements of
 
10 CFR 50.54(w)(1) and the existing level of onsite insurance coverage for IPEC are predicated
 
on the assumption that the reactor is operating. However, IPEC permanently ceased power
 
9 operations on October 31, 1974, April 30, 2020, and April 30, 2021 (For IP1, IP2, and IP3,
 
respectively), and permanently defueled as of January 1976, May 12, 2020, and May 11, 2021
 
(For IP1, IP2, and IP3, respectively). The permanent cessation of operations and defueled
 
status of the facility results in a significant reduction in the number and severity of potential
 
accidents and, correspondingly, a significant reduction in the potential for and severity of onsite
 
property damage. The proposed reduction in the amount of onsite insurance coverage does not
 
impact the probability or consequences of potential accidents. The proposed level of insurance
 
coverage is commensurate with the reduced consequences of potential nuclear accidents at
 
IPEC. Therefore, the NRC staff concludes that granting the requested exemption will not
 
present an undue risk to the health and safety of the public.
 
C. The Exemption Is Consistent with the Common Defense and Security
 
The proposed exemption would not eliminate any requirements associated with physical
 
protection of the site and would not adversely affect the licensees ability to physically secure
 
the site or protect special nuclear material. Physical security measures at IPEC are not affected
 
by the requested exemption. Therefore, the proposed exemption is consistent with the common
 
defense and security.
 
D. Special Circumstances
 
Special circumstances, in accordance with 10 CFR 50.12(a)(2)(ii), are present whenever
 
application of the regulation in the particular circumstances is not necessary to achieve the
 
underlying purpose of the regulation.
 
The underlying purpose of 10 CFR 50.54(w)(1) is to provide reasonable assurance that
 
adequate funds will be available to stabilize reactor conditions and cover onsite cleanup costs
 
associated with site decontamination following an accident that results in the release of a
 
significant amount of radiological material. Since IPEC permanently ceased power operations
 
on October 31, 1974, April 30, 2020, and April 30, 2021 (For IP1, IP2, and IP3, respectively),
 
and permanently defueled as of January 1976, May 12, 2020, and May 11, 2021 (For IP1, IP2,
 
10 and IP3, respectively), it is no longer possible for the radiological consequences of design-basis
 
accidents or other credible events at IPEC to exceed the limits of the EPA PAGs at the
 
exclusion area boundary. The licensee has evaluated the consequences of highly unlikely,
 
beyond-design-basis conditions involving a loss of coolant from the SFP. The analyses show
 
that 15 months after the permanent cessation of power operations, the likelihood of such an
 
event leading to a large radiological release is negligible. The NRC staffs evaluation of the
 
licensees analyses confirms this conclusion.
 
The NRC staff also finds that the licensees proposed $50 million level of onsite
 
insurance is consistent with the bounding cleanup and decontamination cost as discussed in
 
SECY-96-256, to account for the hypothetical rupture of a large liquid radiological waste tank at
 
the IPEC site, should such an event occur. Therefore, the NRC staff concludes that the
 
application of the current requirements in 10 CFR 50.54(w)(1) to maintain $1.06 billion in onsite
 
insurance coverage is not necessary to achieve the underlying purpose of the rule for the
 
permanently shutdown and defueled IPEC reactors.
 
Under 10 CFR 50.12(a)(2)(iii), special circumstances are present whenever compliance
 
would result in undue hardship or other costs that are significantly in excess of those
 
contemplated when the regulation was adopted, or that are significantly in excess of those
 
incurred by others similarly situated.
 
The NRC staff concludes that if the licensee was required to continue to maintain an
 
onsite insurance level of $1.06 billion, the associated insurance premiums would be in excess of
 
those necessary and commensurate with the radiological contamination risks posed by the site.
 
In addition, such insurance levels would be significantly in excess of other decommissioning
 
reactor facilities that have been granted similar exemptions by the NRC.
 
The NRC staff finds that compliance with the existing rule would result in an undue
 
hardship or other costs that are significantly in excess of those contemplated when the
 
11 regulation was adopted and are significantly in excess of those incurred by others similarly
 
situated.
 
Therefore, the special circumstances required by 10 CFR 50.12(a)(2)(ii) and
 
10 CFR 50.12(a)(2)(iii) exist.
 
E. Environmental Considerations
 
The NRCs approval of an exemption from insurance or indemnity requirements belongs
 
to a category of actions that the Commission, by rule or regulation, has declared to be a
 
categorical exclusion after first finding that the category of actions does not individually or
 
cumulatively have a significant effect on the human environment. Specifically, the exemption is
 
categorically excluded from the requirement to prepare an environmental assessment or
 
environmental impact statement in accordance with 10 CFR 51.22(c)(25).
 
Under 10 CFR 51.22(c)(25), granting of an exemption from the requirements of any
 
regulation of Chapter I to 10 CFR, Nuclear Regulatory Commission, is a categorical exclusion
 
provided that: (i) there is no significant hazards consideration; (ii) there is no significant change
 
in the types or significant increase in the amounts of any effluents that may be released offsite;
 
(iii) there is no significant increase in individual or cumulative public or occupational radiation
 
exposure; (iv) there is no significant construction impact; (v) there is no significant increase in
 
the potential for or consequences from radiological accidents; and (vi) the requirements from
 
which an exemption is sought involve surety, insurance, or indemnity requirements.
 
As the Director of the Division of Decommissioning, Uranium Recovery, and Waste
 
Programs in the NRCs Office of Nuclear Material Safety and Safeguards, I have determined
 
that approval of the exemption request involves no significant hazards consideration, as defined
 
in 10 CFR 50.92, Issuance of amendment, because reducing the licensees onsite property
 
damage insurance for IPEC does not: (1) involve a significant increase in the probability or
 
consequences of an accident previously evaluated; (2) create the possibility of a new or
 
different kind of accident from any accident previously evaluated; or (3) involve a significant
 
12 reduction in a margin of safety. The exempted financial protection regulation is unrelated to the
 
operation of IPEC or site activities. Accordingly, there is no significant change in the types or
 
significant increase in the amounts of any effluents that may be released offsite and no
 
significant increase in individual or cumulative public or occupational radiation exposure. The
 
exempted regulation is not associated with construction so there is no significant construction
 
impact. The exempted regulation does not concern the source term (i.e., potential amount of
 
radiation in an accident) or any activities conducted at the site. Therefore, there is no significant
 
increase in the potential for, or consequences of, a radiological accident. In addition, there
 
would be no significant impacts to biota, water resources, historic properties, cultural resources,
 
or socioeconomic conditions in the region resulting from issuance of the requested exemption.
 
The requirement for onsite property damage insurance involves surety, insurance, and
 
indemnity matters only.
 
Therefore, pursuant to 10 CFR 51.22(b) and 51.22(c)(25), Criterion for categorical
 
exclusion; identification of licensing and regulatory actions eligible for categorical exclusion or
 
otherwise not requiring environmental review, no environmental impact statement or
 
environmental assessment need be prepared in connection with the approval of this exemption
 
request.
 
IV. Conclusions
 
Accordingly, the Commission has determined that, pursuant to 10 CFR 50.12(a), the
 
exemption is authorized by law, will not present an undue risk to the public health and safety,
 
and is consistent with the common defense and security. Also, special circumstances are
 
present as set forth in 10 CFR 50.12.
 
Therefore, the Commission hereby grants the licensee an exemption from the
 
requirements of 10 CFR 50.54(w)(1) for IPEC. IPEC permanently ceased power operations on
 
October 31, 1974, April 30, 2020, and April 30, 2021, for IP1, IP2, and IP3, respectively. The
 
exemption from 10 CFR 50.54(w)(1) permits IPEC to reduce the minimum required onsite
 
13 14property damage insurance from $1.06 billion to $50 million 15 months after permanent cessation of power operations, which was August 1, 2022. Because this period has already elapsed, the exemption is effective upon issuance.

NUCLEAR REGULATORY COMMISSION

Docket Nos.50-003, 50-247, and 50-286

Holtec Decommissioning International, LLC,

Holtec Indian Point 2, LLC, and Holtec Indian Point 3, LLC

Indian Point Nuclear Generating Unit Nos. 1, 2, and 3

Exemption

I. Background

Indian Point Nuclear Generating Unit No. 1 (IP1) permanently ceased generation on

October 31, 1974, and all fuel was removed from the IP1 reactor vessel by January 1976. In

1996, the U.S. Nuclear Regulatory Commission (NRC, the Commission) issued an order

approving the safe-storage condition of IP1. In 2003, the NRC issued Amendment No. 52 to

IP1s provisional operating license, which changed the expiration date of the provisional license

to be consistent with that of the Indian Point Nuclear Generating Unit No. 2 (IP2) facility license

at that time. Pursuant to Title 10 of the Code of Federal Regulations (10 CFR) Section

50.82(a)(2), the IP1 license no longer authorizes operation of the reactor or emplacement or

retention of fuel into the reactor vessel. There is no IP1 spent fuel in wet storage at the Indian

Point Energy Center (IPEC) site; IP1 spent fuel is stored onsite in dry cask storage at the

independent spent fuel storage installation (ISFSI).

By letter dated February 8, 2017 (Agencywide Documents Access and Management

System Accession No. ML17044A004), Entergy Nuclear Indian Point 2, LLC, and Entergy

Nuclear Indian Point 3, LLC (the IPEC licensees at that time, collectively, Entergy) certified to

the NRC that they planned to permanently cease power operations at IP2 and Indian Point

Nuclear Generating Unit No. 3 (IP3) by April 30, 2020, and April 30, 2021, respectively. By

letters dated May 12, 2020, and May 11, 2021 (ML20133J902 and ML21131A157), Entergy

certified to the NRC that power operations permanently ceased at IP2 and IP3 on April 30,

1 2020, and April 30, 2021, respectively. In the same letters, Entergy certified to the NRC that the

fuel was permanently removed from the IP2 and IP3 reactor vessels and placed in the IP2 and

IP3 spent fuel pools (SFPs) as of May 12, 2020, and May 11, 2021, respectively.

Based on the docketing of these certifications for permanent cessation of operations and

permanent removal of fuel from the reactor vessels, as specified in 10 CFR 50.82(a)(2), the

10 CFR Part 50 renewed facility licenses for IP2 and IP3 (Nos. DPR-26 and DPR-64,

respectively) no longer authorize operation of the reactors or emplacement or retention of fuel in

the reactor vessels. The facility is still authorized to possess and store irradiated (i.e., spent)

nuclear fuel. At the time of the exemption request described below, spent fuel was stored onsite

at the IP2 and IP3 facilities in the SFPs and in a dry cask ISFSI.

II. Request/Action

By letter dated March 18, 2022 (ML22077A132), Holtec Decommissioning International,

LLC (HDI), one of the licensees of IPEC and an indirect wholly owned subsidiary of Holtec

International (Holtec), requested an exemption on behalf of Holtec Indian Point 2, LLC (a

licensee of IP1 and IP2, referred to as Holtec IP2) and Holtec Indian Point 3, LLC (a licensee of

IP3, and referred to as Holtec IP3), from the requirements of 10 CFR 50.54(w)(1) concerning

onsite liability insurance. HDI, Holtec IP2, and Holtec IP3 are hereafter collectively referred to as

the licensee. The exemption from 10 CFR 50.54(w)(1) would permit the licensee to reduce the

required level of onsite property damage insurance from $1.06 billion to $50 million for IPEC.

The regulation at 10 CFR 50.54(w)(1) requires licensees to have and maintain onsite

property damage insurance to stabilize and decontaminate the reactor(s) and reactor site in the

event of an accident. The onsite insurance coverage must be either $1.06 billion or whatever

amount of insurance is generally available from private sources (whichever is less).

The licensee states that the risk of an incident at a permanently shutdown and defueled

reactor is much less than the risk from an operating power reactor. In addition, since reactor

operation is no longer authorized at IPEC, there are no events that would require the

2 stabilization of reactor conditions after an accident. Similarly, the risk of an accident that would

result in significant onsite contamination at IPEC is also much lower than the risk of such an

event at operating reactors. Therefore, the licensee requested an exemption from

10 CFR 50.54(w)(1) to reduce its onsite property damage insurance from $1.06 billion to

$50 million, commensurate with the reduced risk of an incident at the permanently shutdown

and defueled IPEC site.

III. Discussion

Under 10 CFR 50.12, Specific exemptions, the Commission may, upon application by

any interested person or upon its own initiative, grant exemptions from the requirements of

10 CFR Part 50 when (1) the exemptions are authorized by law, will not present an undue risk

to public health or safety, and are consistent with the common defense and security; and (2) any

of the special circumstances listed in 10 CFR 50.12(a)(2) are present.

The financial protection limits of 10 CFR 50.54(w)(1) were established after the Three

Mile Island Nuclear Station, Unit 2 accident out of concern that licensees may be unable to

financially cover onsite cleanup costs in the event of a major nuclear accident. The specified

$1.06 billion coverage amount requirement was developed based on an analysis of an accident

at a nuclear reactor operating at power, resulting in a large fission product release and requiring

significant resource expenditures to stabilize the reactor and ultimately decontaminate and

cleanup the site.

These cost estimates were developed based on the spectrum of postulated accidents for

an operating nuclear reactor. Those costs were derived from the consequences of a release of

radioactive material from the reactor. Although the risk of an accident at an operating reactor is

very low, the consequences onsite and offsite can be significant. In an operating plant, the high

temperature and pressure of the reactor coolant system (RCS), as well as the inventory of

relatively short-lived radionuclides, contribute to both the risk and consequences of an accident.

With the permanent cessation of reactor operations at IPEC and the permanent removal of the

3 fuel from the reactor vessels, such accidents are no longer possible. As a result, the reactor

vessels, RCS, and supporting systems no longer operate and have no function related to the

storage of the irradiated fuel. Therefore, postulated accidents involving failure or malfunction of

the reactors, RCS, or supporting systems are no longer applicable.

During reactor decommissioning, the largest radiological risks are associated with the

storage of spent fuel onsite. In the exemption request dated March 18, 2022, the licensee

discussed both design-basis and beyond design-basis events involving irradiated fuel stored in

the SFPs. The licensee determined that there are no possible design-basis events at IPEC that

could result in an offsite radiological release exceeding the limits established by the

U.S. Environmental Protection Agencys (EPA) early phase Protective Action Guides (PAGs) of

1 roentgen equivalent man (rem) at the exclusion area boundary, as a way to demonstrate that

any possible radiological releases would be minimal and would not require precautionary

protective actions (e.g., sheltering in place or evacuation). The NRC staff evaluated the

radiological consequences associated with various decommissioning activities and the design

basis accidents at IPEC, in consideration of the permanently shutdown and defueled condition.

The possible design-basis accident scenarios at IPEC have greatly reduced radiological

consequences. Based on its review, the NRC staff concluded that no reasonably conceivable

design-basis accident exists that could cause an offsite release greater than the EPA PAGs.

The only incident that has the potential to lead to a significant radiological release at a

decommissioning reactor is a zirconium fire in the SFP. The zirconium fire scenario is a

postulated, but highly unlikely, beyond design-basis accident scenario that involves loss of

water inventory from the SFP resulting in a significant heat up of the spent fuel, and culminating

in substantial zirconium cladding oxidation and fuel damage. The probability of a zirconium fire

scenario is related to the decay heat of the irradiated fuel stored in the SFP. Therefore, the risks

from a zirconium fire scenario continue to decrease as a function of the time since IPEC has

been permanently shut down.

4 The Commission has previously authorized a lesser amount of onsite financial

protection, based on this analysis of the zirconium fire risk. In SECY-96-256, Changes to

Financial Protection Requirements for Permanently Shutdown Nuclear Power Reactors,

10 CFR 50.54(w) and 10 CFR 140.11, dated December 17, 1996 (ML15062A483), the NRC

staff recommended changes to the power reactor financial protection regulations that would

allow licensees to lower onsite insurance levels to $50 million upon demonstration that the fuel

stored in the SFP can be air-cooled. In its Staff Requirements Memorandum to SECY-96-256,

dated January 28, 1997 (ML15062A454), the Commission supported the NRC staffs

recommendation that, among other things, would allow permanently shutdown power reactor

licensees to reduce commercial onsite property damage insurance coverage to $50 million

when the licensee was able to demonstrate the technical criterion that the spent fuel could be

air-cooled if the SFP was drained of water.

The NRC staff has used this technical criterion to grant similar exemptions to other

decommissioning reactors (e.g., Maine Yankee Atomic Power Station, published in the Federal

Register (FR) on January 19, 1999 (64 FR 2920); Zion Nuclear Power Station, published in the

FR on December 28, 1999 (64 FR 72700); Kewaunee Power Station, published in the FR on

March 24, 2015 (80 FR 15638); Crystal River Unit 3 Nuclear Generation Plant, published in the

FR on May 6, 2015 (80 FR 26100); Oyster Creek Nuclear Generating Station, published in the

FR on December 28, 2018 (83 FR 67365); Pilgrim Nuclear Power Station, published in the FR

on January 14, 2020 (85 FR 2153); Three Mile Island Nuclear Station, Unit 1, published in the

FR on March 26, 2021 (86 FR 16241); and the Duane Arnold Energy Center, published in the

FR on May 18, 2021 (86 FR 26946)). These prior exemptions were based on these licensees

demonstrating that the SFP could be air-cooled, consistent with the technical criterion discussed

above.

In its March 18, 2022, request, the licensee compared the IPEC fuel storage parameters

with those used in NRC generic evaluations of fuel cooling included in NUREG/CR-6451, A

5 Safety and Regulatory Assessment of Generic BWR [Boiling-Water Reactor] and PWR

[Pressurized-Water Reactor] Permanently Shutdown Nuclear Power Plants, dated August 1997

(ML082260098). The analysis described in NUREG/CR-6451 determined that natural air

circulation would adequately cool fuel in the representative PWR.

In SECY-00-0145, Integrated Rulemaking Plan for Nuclear Power Plant

Decommissioning, dated June 28, 2000, and SECY-01-0100, Policy Issues Related to

Safeguards, Insurance, and Emergency Preparedness Regulations at Decommissioning

Nuclear Power Plants Storing Fuel in Spent Fuel Pools, dated June 4, 2001 (ML003721626

and ML011450420, respectively), the NRC staff discussed additional information concerning

SFP zirconium fire risks at decommissioning reactors and associated implications for onsite

property damage insurance. Providing an analysis of when the spent fuel stored in the SFP is

capable of air-cooling is one measure that can be used to demonstrate that the probability of a

zirconium fire is exceedingly low.

In their letter dated March 18, 2022, HDI stated, and the NRC staff confirmed, that the

bounding analyses for the IP2 and IP3 SFPs for beyond design basis events demonstrate that

15 months after shutdown of IP3 a minimum of 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> is available before the fuel cladding

temperature of the hottest fuel assembly in either SFP reaches 900°C with a complete loss of

SFP water inventory. This analysis, Holtec Spent Fuel Pool Heat Up Calculation Methodology

Topical Report, Revision 2, dated December 22, 2021 (ML21357A005 [non-public]), was

submitted by HDI in support of a request for exemptions from certain emergency planning

requirements, dated December 22, 2021 (ML21356B693). HDI provided further information in

, Indian Point Unit Nos. 2 and 3 Spent Fuel Pool Heat Up Calculations, to HDIs

supplemental letter dated February 1, 2022 (ML22032A117).

As stated in NUREG-1738, Technical Study of Spent Fuel Pool Accident Risk at

Decommissioning Nuclear Power Plants, dated February 2001 (ML010430066), 900°C is an

acceptable temperature to use for assessing the onset of fission product release, where the

6 SFP is drained and air cooling is not possible; at least 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> would be available from the time

spent fuel cooling is lost until the hottest fuel assembly reaches a temperature of 900°C. The

10-hour criterion, conservatively, does not consider the time to uncover the fuel and assumes

instantaneous loss of cooling to the fuel. The 10-hour time period is also not intended to

represent the time that it would take to repair all key safety systems or to repair a large SFP

breach. The 10-hour criterion is a conservative period of time in which pre-planned mitigation

measures to provide makeup water or spray to the SFP can be reliably implemented before the

onset of a zirconium cladding ignition. In addition, in the unlikely event that a release is

projected to occur, 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> would provide sufficient time for offsite agencies, if deemed

warranted, to take appropriate action to protect the health and safety of the public.

In the NRC staffs evaluation contained in SECY-22-0102, the NRC staff assessed the

HDI accident analyses associated with the radiological risks from a zirconium fire at a

permanently shutdown and defueled IPEC after 15 months of fuel decay. For the highly unlikely

beyond design-basis accident scenario where the SFP coolant inventory is lost in such a

manner that all methods of heat removal from the spent fuel are no longer available, the NRC

staff found that there will be a minimum of 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> from the initiation of the accident until the

cladding reaches a temperature where offsite radiological release might occur. The NRC staff

finds that 10 hours1.157407e-4 days <br />0.00278 hours <br />1.653439e-5 weeks <br />3.805e-6 months <br /> is sufficient time to support deployment of mitigation equipment, consistent

with plant conditions, to prevent the zirconium cladding from reaching a point of rapid oxidation.

As a result, the likelihood that such a scenario would progress to a zirconium fire is deemed not

credible.

Based on the evaluation in SECY-96-256, as well as analysis done by HDI and verified

by the NRC staff, the NRC staff determined $50 million to be an adequate level of onsite

property damage insurance for a decommissioning reactor once the spent fuel in the SFP is no

longer susceptible to a zirconium fire. However, the NRC staff has postulated that there is still a

potential for other radiological incidents at a decommissioning reactor that could result in

7 significant onsite contamination besides a zirconium fire. In SECY-96-256, the NRC staff cited

the rupture of a large, contaminated liquid storage tank (~450,000 gallons) causing soil

contamination and potential groundwater contamination as the costliest postulated event to

decontaminate and remediate (other than an SFP zirconium fire). The postulated large liquid

radiological waste storage tank rupture event was determined to have a bounding onsite

cleanup cost of approximately $50 million. Therefore, the NRC staff determined that the

licensees proposal to reduce onsite insurance to a level of $50 million would be consistent with

the bounding cleanup and decontamination cost, as discussed in SECY-96-256, to account for

the postulated rupture of a large liquid radiological waste tank at the IPEC site, should such an

event occur.

The NRC staff has determined that the licensees proposed reduction in onsite property

damage insurance coverage to a level of $50 million is consistent with SECY-96-256 and

subsequent insurance considerations resulting from additional zirconium fire risks as discussed

in SECY-00-0145 and SECY-01-0100, as well as NUREG/CR-6451 and NUREG-1738. In

addition, the NRC staff notes that similar exemptions have been granted to other permanently

shutdown and defueled power reactors, upon demonstration that the criterion of the zirconium

fire risks from the irradiated fuel stored in the SFP is of negligible concern. The NRC staff

concluded that 15 months after the permanent shutdown date of IP3 of April 30, 2021, sufficient

irradiated fuel decay time will have elapsed at IPEC to decrease the probability of an onsite

radiological release from a postulated zirconium fire accident to negligible levels. In addition, the

licensees proposal to reduce onsite insurance to a level of $50 million is consistent with the

maximum estimated cleanup costs for the recovery from the rupture of a large liquid radwaste

storage tank.

The NRC staff also notes that in accordance with letters submitted by HDI on February

15, 2023, and October 16, 2023 (ML23046A102 and ML23289A158), all the spent fuel from the

8 IP2 and IP3 SFPs has been transferred to dry storage within the ISFSI. As such, an initiating

event that would threaten SFP integrity is no longer applicable.

A. The Exemption is Authorized by Law

The requested exemption from 10 CFR 50.54(w)(1) would allow the licensee to reduce

the minimum coverage limit for onsite property damage insurance. As stated above, 10 CFR

50.12 allows the NRC to grant exemptions from the requirements of 10 CFR Part 50 when the

exemptions are authorized by law.

As explained above, the NRC staff has determined that the licensees proposed

reduction in onsite property damage insurance coverage to a level of $50 million is consistent

with SECY-96-256. Moreover, the NRC staff concluded that 15 months after the permanent

cessation of power operations, sufficient irradiated fuel decay time will have elapsed at IPEC to

decrease the probability of an onsite and offsite radiological release from a postulated zirconium

fire accident to negligible levels. In addition, the licensees proposal to reduce onsite insurance

to a level of $50 million is consistent with the maximum estimated cleanup costs for the recovery

from the rupture of a large liquid radiological waste storage tank.

The NRC staff has determined that granting the licensees proposed exemption will not

result in a violation of the Atomic Energy Act of 1954, as amended, or the Commissions

regulations. Therefore, based on its review of the licensees exemption request as discussed

above, and consistent with SECY-96-256, the NRC staff concludes that the exemption is

authorized by law.

B. The Exemption Presents No Undue Risk to the Public Health and Safety

The onsite property damage insurance requirements of 10 CFR 50.54(w)(1) were

established to provide financial assurance that following a significant nuclear incident, onsite

conditions could be stabilized and the site decontaminated. The requirements of

10 CFR 50.54(w)(1) and the existing level of onsite insurance coverage for IPEC are predicated

on the assumption that the reactor is operating. However, IPEC permanently ceased power

9 operations on October 31, 1974, April 30, 2020, and April 30, 2021 (For IP1, IP2, and IP3,

respectively), and permanently defueled as of January 1976, May 12, 2020, and May 11, 2021

(For IP1, IP2, and IP3, respectively). The permanent cessation of operations and defueled

status of the facility results in a significant reduction in the number and severity of potential

accidents and, correspondingly, a significant reduction in the potential for and severity of onsite

property damage. The proposed reduction in the amount of onsite insurance coverage does not

impact the probability or consequences of potential accidents. The proposed level of insurance

coverage is commensurate with the reduced consequences of potential nuclear accidents at

IPEC. Therefore, the NRC staff concludes that granting the requested exemption will not

present an undue risk to the health and safety of the public.

C. The Exemption Is Consistent with the Common Defense and Security

The proposed exemption would not eliminate any requirements associated with physical

protection of the site and would not adversely affect the licensees ability to physically secure

the site or protect special nuclear material. Physical security measures at IPEC are not affected

by the requested exemption. Therefore, the proposed exemption is consistent with the common

defense and security.

D. Special Circumstances

Special circumstances, in accordance with 10 CFR 50.12(a)(2)(ii), are present whenever

application of the regulation in the particular circumstances is not necessary to achieve the

underlying purpose of the regulation.

The underlying purpose of 10 CFR 50.54(w)(1) is to provide reasonable assurance that

adequate funds will be available to stabilize reactor conditions and cover onsite cleanup costs

associated with site decontamination following an accident that results in the release of a

significant amount of radiological material. Since IPEC permanently ceased power operations

on October 31, 1974, April 30, 2020, and April 30, 2021 (For IP1, IP2, and IP3, respectively),

and permanently defueled as of January 1976, May 12, 2020, and May 11, 2021 (For IP1, IP2,

10 and IP3, respectively), it is no longer possible for the radiological consequences of design-basis

accidents or other credible events at IPEC to exceed the limits of the EPA PAGs at the

exclusion area boundary. The licensee has evaluated the consequences of highly unlikely,

beyond-design-basis conditions involving a loss of coolant from the SFP. The analyses show

that 15 months after the permanent cessation of power operations, the likelihood of such an

event leading to a large radiological release is negligible. The NRC staffs evaluation of the

licensees analyses confirms this conclusion.

The NRC staff also finds that the licensees proposed $50 million level of onsite

insurance is consistent with the bounding cleanup and decontamination cost as discussed in

SECY-96-256, to account for the hypothetical rupture of a large liquid radiological waste tank at

the IPEC site, should such an event occur. Therefore, the NRC staff concludes that the

application of the current requirements in 10 CFR 50.54(w)(1) to maintain $1.06 billion in onsite

insurance coverage is not necessary to achieve the underlying purpose of the rule for the

permanently shutdown and defueled IPEC reactors.

Under 10 CFR 50.12(a)(2)(iii), special circumstances are present whenever compliance

would result in undue hardship or other costs that are significantly in excess of those

contemplated when the regulation was adopted, or that are significantly in excess of those

incurred by others similarly situated.

The NRC staff concludes that if the licensee was required to continue to maintain an

onsite insurance level of $1.06 billion, the associated insurance premiums would be in excess of

those necessary and commensurate with the radiological contamination risks posed by the site.

In addition, such insurance levels would be significantly in excess of other decommissioning

reactor facilities that have been granted similar exemptions by the NRC.

The NRC staff finds that compliance with the existing rule would result in an undue

hardship or other costs that are significantly in excess of those contemplated when the

11 regulation was adopted and are significantly in excess of those incurred by others similarly

situated.

Therefore, the special circumstances required by 10 CFR 50.12(a)(2)(ii) and

10 CFR 50.12(a)(2)(iii) exist.

E. Environmental Considerations

The NRCs approval of an exemption from insurance or indemnity requirements belongs

to a category of actions that the Commission, by rule or regulation, has declared to be a

categorical exclusion after first finding that the category of actions does not individually or

cumulatively have a significant effect on the human environment. Specifically, the exemption is

categorically excluded from the requirement to prepare an environmental assessment or

environmental impact statement in accordance with 10 CFR 51.22(c)(25).

Under 10 CFR 51.22(c)(25), granting of an exemption from the requirements of any

regulation of Chapter I to 10 CFR, Nuclear Regulatory Commission, is a categorical exclusion

provided that: (i) there is no significant hazards consideration; (ii) there is no significant change

in the types or significant increase in the amounts of any effluents that may be released offsite;

(iii) there is no significant increase in individual or cumulative public or occupational radiation

exposure; (iv) there is no significant construction impact; (v) there is no significant increase in

the potential for or consequences from radiological accidents; and (vi) the requirements from

which an exemption is sought involve surety, insurance, or indemnity requirements.

As the Director of the Division of Decommissioning, Uranium Recovery, and Waste

Programs in the NRCs Office of Nuclear Material Safety and Safeguards, I have determined

that approval of the exemption request involves no significant hazards consideration, as defined

in 10 CFR 50.92, Issuance of amendment, because reducing the licensees onsite property

damage insurance for IPEC does not: (1) involve a significant increase in the probability or

consequences of an accident previously evaluated; (2) create the possibility of a new or

different kind of accident from any accident previously evaluated; or (3) involve a significant

12 reduction in a margin of safety. The exempted financial protection regulation is unrelated to the

operation of IPEC or site activities. Accordingly, there is no significant change in the types or

significant increase in the amounts of any effluents that may be released offsite and no

significant increase in individual or cumulative public or occupational radiation exposure. The

exempted regulation is not associated with construction so there is no significant construction

impact. The exempted regulation does not concern the source term (i.e., potential amount of

radiation in an accident) or any activities conducted at the site. Therefore, there is no significant

increase in the potential for, or consequences of, a radiological accident. In addition, there

would be no significant impacts to biota, water resources, historic properties, cultural resources,

or socioeconomic conditions in the region resulting from issuance of the requested exemption.

The requirement for onsite property damage insurance involves surety, insurance, and

indemnity matters only.

Therefore, pursuant to 10 CFR 51.22(b) and 51.22(c)(25), Criterion for categorical

exclusion; identification of licensing and regulatory actions eligible for categorical exclusion or

otherwise not requiring environmental review, no environmental impact statement or

environmental assessment need be prepared in connection with the approval of this exemption

request.

IV. Conclusions

Accordingly, the Commission has determined that, pursuant to 10 CFR 50.12(a), the

exemption is authorized by law, will not present an undue risk to the public health and safety,

and is consistent with the common defense and security. Also, special circumstances are

present as set forth in 10 CFR 50.12.

Therefore, the Commission hereby grants the licensee an exemption from the

requirements of 10 CFR 50.54(w)(1) for IPEC. IPEC permanently ceased power operations on

October 31, 1974, April 30, 2020, and April 30, 2021, for IP1, IP2, and IP3, respectively. The

exemption from 10 CFR 50.54(w)(1) permits IPEC to reduce the minimum required onsite

13 14property damage insurance from $1.06 billion to $50 million 15 months after permanent cessation of power operations, which was August 1, 2022. Because this period has already elapsed, the exemption is effective upon issuance.
