SUPPLEMENTARY INFORMATION:

I. Discussion

On February 13, 2023 (88 FR 9106), the NRC published a direct f inal rule

amending its regulations in part 72 of title 10 of the Code of Federal Regulations

(10 CFR) to revise the Holtec International HI-STORM 100 Cask S ystem listing within

the List of approved spent fuel storage casks to renew the in itial certificate

(Amendment No. 0) and Amendment Nos. 1 through 15 to Certificat e of Compliance

No. 1014. The renewal of the initial certificate and Amendment Nos. 1 through 15 for

40 years revised the certificate of compliances conditions and technical specifications to

address aging management activities related to the structures, systems, and

components important to safety of the dry storage system to ens ure that these will

maintain their intended functions during the period of extended storage operations.

In the direct final rule, published on February 13, 2023, the N RC stated that if no

significant adverse comments were received, the direct final ru le would become effective

on May 1, 2023. The comment period closed on March 15, 2023; ho wever, on

3 March 22, 2023, in response to requests for an extension of the public comment period,

the NRC reopened the public comment period to allow the public more time to comment

on the action (88 FR 17164). The re-opened comment period close d on April 14, 2023.

On April 26, 2023 (88 FR 25271), the NRC published a document t hat indefinitely

delayed the effective date of the direct final rule to provide the NRC staff sufficient time

to evaluate and respond to public comments.

The NRC received eight comment submissions on the companion pro posed rule

published on February 13, 2023 (88 FR 9195). The comments were submitted by four

individuals, and a joint comment was provided on behalf of five nongovernmental

organizations. An electronic copy of the comment submissions ca n be obtained from the

Federal rulemaking website https://www.regulations.gov under Do cket ID NRC2022-

0109. The comments are also available in ADAMS using the Access ion numbers shown

in the table in the Availability of Documents section of this document.

The NRC binned the comments by topic and evaluated the comments using the

criteria stated in the direct final rule. The NRC is providing a response to the comments

in section II. of this document, Public Comment Responses. So me comments were not

unique to this action, in that they raised issues the NRC has a ddressed in previous spent

fuel storage actions, (e.g., guidance for evaluating the aging management programs).

Other comments were on topics that are outside of the scope of this rulemaking, such as

transportation, cask design bases, and storage at a consolidate d interim storage facility.

In addition, some comments pertain to the regulations in 10 CFR part 72 rather than the

safety of the Holtec International HI-STORM 100 Cask System des ign and are also

outside of the scope of this rulemaking.

For ease of reference, the criteria for a significant adverse c omment are repeated

here:

A significant adverse comment is a comment where the commenter explains why

4 the rule would be inappropriate, including challenges to the ru les underlying premise or

approach, or would be ineffective or unacceptable without a cha nge. A comment is

adverse and significant if:

(1) The comment opposes the rule and provides a reason sufficie nt to require a

substantive response in a notice-and-comment process. For examp le, a substantive

response is required when:

(a) The comment causes the NRC to reevaluate (or reconsider) it s position or

conduct additional analysis;

(b) The comment raises an issue serious enough to warrant a sub stantive

response to clarify or complete the record; or

(c) The comment raises a relevant issue that was not previously addressed or

considered by the NRC.

(2) The comment proposes a change or an addition to the rule, a nd it is apparent

that the rule would be ineffective or unacceptable without inco rporation of the change or

addition.

(3) The comment causes the NRC to make a change (other than edi torial) to the

rule, certificate of compliance, or technical specifications.

The NRC evaluated the comments against these criteria and deter mined that the

public comments received on this action did not warrant any add itions or changes (other

than editorial) to the final rule, the certificates of complian ce, or the accompanying

technical specifications. The NRC is not making substantive cha nges to the rule; it is

apparent that the rule is effective and acceptable as proposed, without the need for a

substantive change or addition. The comments did not raise a re levant issue that was

not previously addressed or considered by the NRC, and the comm ents did not cause

the NRC to either: 1) reevaluate or reconsider its position, or 2) conduct additional

analyses.

5 The NRC has determined that none of the comments were significa nt adverse

comments. Therefore, the NRC is correcting and confirming the d irect final rule

amending the listing for Certificate of Compliance No. 1014, th e Holtec International

HISTORM 100 Cask System design, to renew the NRCs approval of th e certificate of

compliance and is announcing the effective date.

II. Public Comment Responses

Comment: The joint comment raised concerns regarding the transport of storage

canisters under 10 CFR part 71.

Response: This rulemaking only applies to the use of the Holtec Interna tional

HISTORM 100 Cask System design in an independent spent fuel stora ge installation at

power reactor sites. The use of a component of the Holtec Inter national HISTORM 100

Cask System designthe multi-purpose canisterin transportation, would fall under

NRCs regulations in 10 CFR part 71, which is outside of the sc ope of this rulemaking.

Allowing the Holtec International HI-STORM 100 Cask System desi gn to be used for the

storage of spent fuel under the general license issued by 10 CF R 72.210 neither affects

nor contributes to the evaluation of its use during transportat ion.

Comment: The joint comment re-submitted a comment that had previously been

submitted to the NRC on the Interim Storage Partners Consolidat ed Interim Storage

Facility Project Draft Environmental Impact Statement regarding the need to consider the

foreseeable environmental impacts of the entire project, includ ing transporting spent

nuclear fuel to and from the proposed Consolidated Interim Stor age Facility in Texas.

Response: This rulemaking action only approves the use of the Holtec

International HISTORM 100 Cask System design under the renewed Certificate of

6 Compliance No. 1014 for the initial certificate (Amendment No. 0) and Amendment

Nos. 1 through 15 under the general license issued by 10 CFR 72.210, which involves

the storage of spent nuclear fuel in an independent spent fuel storage installation at

power reactor sites. This does not include the use of the Holte c International

HISTORM 100 Cask System design at a consolidated interim storage facility. This

comment is outside the scope of this rulemaking. Additionally, the use of a Holtec

International HISTORM 100 Cask System design at a consolidated interim storage

facility would be authorized under a specific license and, befo re such approval would be

granted, there would be an opportunity to request a hearing and to petition to intervene.

Comment: Three comments raised concerns regarding the design bases for the

Holtec International HI-STORM 100 Cask System design.

Response: Pursuant to 10 CFR part 72, the design bases for a cask syste m

design include reference bounds for the design and analyses of postulated accidents

caused by severe natural events and severe human-induced events. The renewal of the

Holtec International HI-STORM 100 Cask System design does not i nvolve reevaluation

of the approved design bases, changes to the approved design ba ses, nor changes to

the fabrication of the cask system. Rather, the renewal require s aging management

programs to ensure that structures, systems, and components imp ortant to safety will

continue to perform their intended functions, as designed, duri ng the period of extended

operation, thus maintaining the approved design bases during th e period of extended

operation. The issue of approved design bases is outside of the scope of this

rulemaking.

Comment: The joint comment objected to the use of the direct final rul e process

by the NRC and requested the NRC withdraw the direct final rule. The comment stated

7 that the direct final rule process was not appropriate because the rule appears to be

controversial and because the process appears to violate the Na tional Environmental

Policy Act of 1969 and the Administrative Procedure Act (APA). The comment noted that

the direct final rule does not fall within the good cause excep tion in 10 CFR 2.804(d).

Response: The NRC disagrees with this comment. Direct final rulemaking1 is a

process for expediting the issuance of noncontroversial rules a nd is a variation on

section 553 notice-and-comment rulemaking under the APA. The NR C issued a direct

final rule and a companion proposed rule in the same issue of t he Federal Register and

requested public comment. In the NRCs description of the direc t final rulemaking

process, the NRC explains that a direct final rule, while not e xplicitly delineated by the

APA, does comply with the APA and includes all of the essential elements of rulemaking

required by the APA. In this rulemaking, the NRC has provided n otice and opportunity

for comment; a statement of basis and purpose; and publication of the rule not less than

30 days prior to its effective date (see, https://www.nrc.gov/a bout-

nrc/regulatory/rulemaking/rulemaking-process/direct-final-rule. html).

The NRCs requirements at 10 CFR part 72 currently list 15 appr oved certificates

of compliance for spent fuel storage casks. NRC has conducted r ulemaking to renew six

of these certificates of compliance. All six certificate of com pliance renewals included

aging management programs and invo lved 40-year terms. The Agenc y considers these

prior rulemaking actions to be non-controversial because the NR C either did not receive

any comments opposing the renewals or did not receive any signi ficant adverse

comments. The NRCs decision to use the direct final rulemaking process for the

renewal of Certificate of Compliance No. 1014 (Holtec Internati onal HISTORM 100

1 The Administrative Conference of the United States (ACUS) has endorsed the use of the direct final rule process as a means for expediting rulemaking (see ACUS Recommendation 95-4, Procedures for Non-Controversial and Expedited Rulemaking (60 FR 43110; August 18, 1995)).

8 Cask System design) was based on this experience.

Additionally, this rulemaking did adhere to the requirements of the National

Environmental Policy Act of 1969. In the direct final rule, the NRC published an

environmental assessment and a final finding of no significant impact. The NRC

previously considered the impacts from the continued storage of spent fuel, including in

the Generic Environmental Impact Statement for Continued Storage of Spent Nuclear

Fuel: Final Report (NUREG-2157, Volumes 1 and 2) (2014).

Comment: One commenter requested the NRC make all the renewed

amendments expire on the same day. The commenter noted the expi ration dates for the

early certificates (i.e., the initial certificate (Amendment No. 0) and Amendment Nos. 1

through 6) have an expiration date of June 1, 2020; however, th e later Amendment

certificates have an expiration date of May 31, 2020.

Response: The NRC agrees with this comment regarding an editorial issue. This

change has no substantive effect on the requirements; because t his comment is limited

to editorial changes that do not affect the renewal of the cert ificate of compliance, it is

not considered to be a significant adverse comment. The NRC has made editorial

corrections to the certificates of compliance in response to th is comment.

Comment: The NRC received two comments on the topic of NRCs generic

technical basis for canister cracking, the canister aging manag ement program, and the

need for periodic reviews and updates to the aging management p rograms based on

new information from research and operating experience. The NRC also received a

comment stating that NRC should track the U.S. Department of En ergys (DOEs)

research efforts in this area and that the DOEs ongoing resear ch does not support the

NRC conclusions in its Safety Evaluation Report. This comment a lso noted that

9 comparing the applicants aging management program elements to program elements

developed by industry does not constitute sufficient due dilige nce by NRC.

Response: The NRC previously considered and addressed these concerns

during the development of its general technical basis for canis ter aging management.

The NRC established a generic techni cal basis for the safety review of storage renewal

applications through guidance in NUREG2214, Managing Aging Processes in Storage

(MAPS) Report. NUREG2214 establishes a generic technical basis in terms of the

evaluation of (1) aging mechanisms and effects that could affec t the ability of structures,

systems, and components important to safety to fulfill their sa fety functions in the period

of extended operation (i.e., credible aging mechanisms and effe cts) and (2) aging

management approaches to address credible aging effects, includ ing examples of aging

management programs that are considered generically acceptable to address the

credible aging effects to ensure that the design bases will be maintained in the period of

extended operation.

The NRC sought public input during development of NUREG2214 and related

guidance. The NRC responded to the public comments on the draft guidance and

finalized the guidance after considering the comments provided by the public. The NRC

issued its responses at the time it announced the issuance of N UREG2214 (84 FR

39022; August 8, 2019), NUREG1927, Revision 1, Standard Review Plan for Renewal

of Specific Licenses and Certificates of Compliance for Dry Sto rage of Spent Nuclear

Fuel (81 FR 44054; July 6, 2016), and NUREG2224, Dry Storage and Transportation

of High Burnup Spent Nuclear Fuel (85 FR 77267; December 1, 20 20). The comments

submitted on this rulemaking did not provide new information th at was not previously

considered during the development of this NRC guidance.

The NRC disagrees with the commenters assertion about the sign ificance of

10 ongoing research and the extent to which it supports or contrad icts NRC staff

conclusions. This ongoing research is compatible with the NRCs conclusions in the

NRCs Safety Evaluation Report. The NRC has conducted and conti nues to conduct

research associated with stress corrosion cracking and coordina tes its research efforts

with DOE in this area. In addition, the NRC collaborates with D OE and national

counterparts, consensus committees, industry, and international partners to share

research, knowledge, and operating experience related to degrad ation and aging of cask

systems. The NRC considers this p ool of information in its regulatory framework for

spent fuel storage.

The NRC recognizes that there will be new information gained in the period of

extended operation, including oper ating experience and findings from research and

development. Therefore, as described in NUREG1927, NUREG2214, and Regulatory

Guide 3.76, Implementation of Aging Management Requirements fo r Spent Fuel

Storage Renewals (86 FR 38506; July 21, 2021), aging managemen t programs include

learning aspects designed to appropriately address and respond to new information.

These learning programmatic features are called tollgates, wh ich offer a structured

approach for: (1) periodically reviewing site-specific and indu strywide operating

experience and data from applicable research and industry initi atives at specific times

during the period of extended operation; and (2) performing a s afety assessment that

confirms the programs effectiveness or otherwise identifies a need to enhance or modify

the program in a timely manner to address any emerging aging is sues.

As aging management inspections of canisters are performed at i ndependent

spent fuel storage installations, licensees and certificate of compliance holders will

upload the inspection results to the Independent Spent Fuel Sto rage Installation Aging

Management Institute of Nuclear Power Operations Database (AMID ), and this operating

experience will be shared across the industry through licensee access to this database

11 by the independent spent fuel storage installation sites and by certificate of compliance

holders. The implementation of tollgate assessments and use of AMID provides

reasonable assurance that the aging management programs will co ntinue to effectively

manage aging effects during the period of extended operation.

The NRC disagrees with the commenters statement regarding the comparison of

the applicants aging management program elements to program el ements developed by

industry. During the NRCs review of Holtec Internationals ren ewal application for the

HISTORM 100 Cask System design, the NRC evaluated Holtec Internat ionals technical

basis for its aging management review and aging management prog rams and compared

it to the generic technical basis in NUREG2214. The generic technical basis in

NUREG2214 was developed by the NRC, not by the industry. The guidanc e in

NUREG2214 provides examples of aging management programs that are co nsidered

generically acceptable to address the credible aging mechanisms evaluated in the

guidance to ensure that the design bases of the cask system wil l be maintained in the

period of extended operation. The NRC found the Holtec Internat ional aging

management program acceptable. The NRC Safety Evaluation Report documents the

consistency between the applicants canister aging management p rogram and the

NUREG2214 canister aging management program.

Comment: The NRC received two comments regarding scratching and cracki ng

of canisters. The first comment, from the joint comments, state d that NRC has not

reviewed the long-term impact of the scraping, gouging, and scr atching of canisters

when they are loaded into the casks, including the potential fo r increased and

accelerated corrosion. The second comment noted that the Holtec International

HISTORM 100 Cask System design above ground system may cause cani sters to

12 scratch and scrape against the carbon steel vertical channels i n the overpack cask,

leading to potential initiation of carboninduced pit corrosion cracking and a serious

accelerated canister degradation condition.

Response: The comments on the topic of scratching and cracking of canis ters do

not introduce new information that was not already considered d uring the NRCs

development of NUREG2214 and during the review of Holtec Internationals renewal

application for the Holtec HISTORM 100 Cask System design. Welded stainless steel

dry storage canisters, like those used in the HI STORM 100 Cask System design, may

contact dissimilar metal surfac es, and may get scraped, scratch ed, or gouged during

handling and loading into the storage overpack. During the deve lopment of

NUREG2214, the NRC considered these potential effects and the potent ial for handling

practices to result in the contact and transfer of carbon steel onto the surface of the

stainless-steel canister.

NUREG2214 identifies stress corrosion cracking as a credible aging e ffect for

canisters and includes an aging management program for canister s to identify and

manage localized corrosion (a potential precursor to stress cor rosion cracking) and

stress corrosion cracking. NUREG2214 notes the potential for handling practices to

result in contact and transfer of iron (i.e., carbon steel) ont o the stainless-steel canister

surface, which can create localized corrosion. The NUREG2214 canister aging

management program addresses aging effects and provides reasona ble assurance that

aging associated with any initial defects, scrapes, or effects of dissimilar materials being

in contact will not compromise the intended functions of the ca nister during the period of

extended operation.

NUREG2214 provides examples of aging management programs that the NR C

considers as being generically acceptable to address those cred ible aging mechanisms

13 evaluated in the guidance to ensure that the design bases of dr y storage systems will be

maintained. In its review of the renewal application for the Ho ltec International

HISTORM 100 Cask System design, the NRC staff evaluated Holtec In ternationals

technical basis for its aging management review and aging manag ement programs for

the Holtec International HISTORM 100 Cask System design and compared it to the

generic technical basis in NUREG2214. The NRC Safety Evaluation Report documents

the consistency between the applicants canister aging manageme nt program and the

NUREG-2214 canister aging managemen t program. Consistent with the NUREG2214

canister aging management program, the Holtec International HI STORM 100 Cask

System design canister aging management program includes inspec tions of canister

surfaces to identify the presence of red-orange corrosion depos its that may indicate iron

transfer onto the stainless-steel canister surface. Any areas o f corrosion that are found

and identified are subject to additional examination and evalua tion.

Additionally, the Holtec International HISTORM 100 Cask System design

canister aging management program includes criteria to inspect those canisters that are

most susceptible to degradation. The aging management program f or the Holtec

International HISTORM 100 Cask System design considers the susceptibility crite ria in

Electric Power Research Institute (EPRI) TR-3002005371, Suscep tibility Assessment

Criteria for Chloride-Induced Stress Corrosion Cracking (CISCC) of Welded Stainless-

Steel Canisters for Dry Cask Storage Systems (referenced also in NUREG-2214). The

EPRI report identifies areas of mechanical damage (e.g., gouge s) and scraping during

handling as being the most susceptible to aging. The concerns expressed in the

comments (i.e., long-term effects of any scraping, gouging, and scratching of canisters

or contact between dissimilar materials when canisters are load ed into the storage

overpack including the potential for increased and accelerated corrosion) are addressed

14 in the canister aging management program.

Comment: The joint comment expressed concern with radiation effects an d dose

limits.

Response: This comment raises issues that are outside of the scope of t his

rulemaking. The NRC establishes safety standards for protection against radiation,

including public dose limits, in 10 CFR part 20, Standards for Protection against

Radiation. The regulations in 10 CFR part 72 also include dose limits for spent fuel

storage. The current requirements in 10 CFR parts 20 and 72 are protective of public

health and safety and the environment.
