4 as shown by the rail sensitivity case 

in this study (e.g., the GA–4 truck spent 

fuel transport can hold four PWR fuel 

assemblies, which would reduce the 

PWR cumulative doses by a factor of 4). 

The NRC staff found total accidental 

population risk per year due to transport 

of spent ATF, including spent ATF with 

increased enrichment and higher 

burnup levels, continued to demonstrate 

the low risks from both radiological and 

nonradiological accidents and is 

consistent with past transportation 

studies. The greater risk to a member of 

the public would be physical harm from 

an actual vehicle collision involving a 

spent ATF shipment, if such an event 

ever happens. While the nonradiological 

risk is the greater risk, the results of this 

study demonstrate that those risks 

would still not be significant and are 

less than the common (nonradiological) 

cause environmental risks of Table S–4. 

The results for spent ATF with 

increased enrichment and higher 

burnup are consistent with the 

environmental impacts associated with 

the transportation of fuel and 

radioactive wastes to and from currentgeneration reactors presented in Table 

S–4 of 10 CFR 51.52. 

Based on the results of the impact 

analysis, shipment of near-term ATF 

technologies with enrichments of up to 

8 (wt%) uranium-235 (U–235) and 

higher burnup levels of up to 80 

gigawatt days per metric ton of uranium 

(GWd/MTU) would not significantly 

change the potential impacts of either 

incident-free or accident transportation 

risk. Hence, the transportation impacts 

of spent ATF are bounded by Table S– 

4. Therefore, the results of this analysis 

could serve as a reference in helping to 

address the environmental impacts of 

ATF licensing without a detailed sitespecific transportation analysis, as long 

as the ATF is within the enrichment and 

burnup levels with the associated fuel 

assembly radionuclide inventory and 

parameters applied in the analyses of 

this proposed NUREG. 

In the case of decommissioning, the 

expected impacts from deployment and 

use of ATF with increased enrichment 

and higher burnup levels would be the 

same as or slightly less than those from 

decommissioning nuclear power plants 

operating with the existing fuel. 

Additionally, the expected 

Decommissioning GEIS and guidance 

updates could build upon the analysis 

from this study to specifically address 

the decommissioning of a LWR 

deploying and using ATF. 

Therefore, based on findings in this 

study, the NRC staff concludes that the 

reevaluated findings addressing nearterm ATF technologies (i.e., coated 

cladding, doping, and FeCrAl cladding) 

indicate the environmental effects 

associated with deploying and using 

ATF would be bounded by the NRC 

staff’s prior analysis with enrichments 

up to 8 wt% U–235 and extending peakrod burnup to 80 GWd/MTU for the 

uranium fuel cycle, transportation of 

fuel and waste, and decommissioning. 

Additionally, if in a future licensing 

action, the enrichment and burnup 

levels are greater than 8 wt% U–235 and 

80 GWd/MTU, respectively, and for the 

deployment and use of long-term ATF 

technologies, the study could provide 

guidance for completing the needed 

revised analysis. 

As the NRC staff continues to prepare 

to review license applications related to 

ATF technologies and fuel with 

increased enrichment and higher 

burnup levels, the NRC staff will 

evaluate new industry developments 

and other activities before publishing 

the final NUREG to consider further 

refinements of the ATF environmental 

evaluation. For example, such new 

information could include results from 

ongoing licensing actions regarding the 

use of higher enrichment levels in fuel 

fabrication (ADAMS Accession No. 

ML22175A070). 

III. Specific Requests for Comments 

The NRC is seeking advice and 

recommendations from the public on 

the draft NUREG. We are particularly 

interested in comments and supporting 

rationale from the public on the 

following: 

Transportation Accident Release 

Fractions 

1. Previous transportation accident 

analyses have relied upon the use of 

release fractions in Table 7.31 from 

NUREG/CR–6672, ‘‘Reexamination of 

Spent Fuel Shipment Risk Estimates,’’ 

(ADAMS Accession No. ML003698324) 

for burnup levels up to 60 GWd/MTU. 

By subjecting LWR nuclear fuel to 

higher burnup levels, the radionuclide 

inventory available to be released is 

greater and material issues such as 

cladding embrittlement, fuel 

fragmentation, and additional 

diffusional release of fission products 

are expected to result in greater release 

fractions than assessed in NUREG/CR– 

6672. Therefore, Appendix B of the draft 

NUREG assessed the potential effects 

due to higher radiological material 

release fractions from the physical 

effects of higher burnup levels on the 

fuel pin cladding and the uranium fuel 

pellets. 

The NRC is seeking comment on the 

use of release fractions developed in 

Appendix B of the draft NUREG for 

higher burnup levels than previously 

considered under transportation 

accident conditions.

RAILROAD RETIREMENT BOARD 

Agency Forms Submitted for OMB 

Review, Request for Comments 

In accordance with the Paperwork 

Reduction Act of 1995 (44 U.S.C. 

chapter 35), the Railroad Retirement 

Board (RRB) is forwarding 4 Information 

Collection Requests (ICR) to the Office 

of Information and Regulatory Affairs 

(OIRA), Office of Management and 

Budget (OMB). Our ICR describes the 

information we seek to collect from the 

public. Review and approval by OIRA 

ensures that we impose appropriate 

paperwork burdens. 

The RRB invites comments on the 

proposed collections of information to 

determine (1) the practical utility of the 

collections; (2) the accuracy of the 

estimated burden of the collections; (3) 

ways to enhance the quality, utility, and 

clarity of the information that is the 

subject of collection; and (4) ways to 

minimize the burden of collections on 

respondents, including the use of 

automated collection techniques or 

other forms of information technology. 

Comments to the RRB or OIRA must 

contain the OMB control number of the 

ICR. For proper consideration of your 

comments, it is best if the RRB and 

OIRA receive them within 30 days of 

the publication date. 

1. Title and Purpose of information 

collection: Certification Regarding 

Rights to Unemployment Benefits; OMB 

3220–0079. 

Under section 4 of the Railroad 

Unemployment Insurance Act (RUIA) 

(45 U.S.C. 354), an employee who leaves 

work voluntarily is disqualified for 

unemployment benefits unless the 

employee left work for good cause and 

is not qualified for unemployment 

benefits under any other law. RRB Form 

UI–45, Claimant’s Statement— 

Voluntary Leaving of Work, is used by 

the RRB to obtain the claimant’s 

statement when the claimant, the 

claimant’s employer, or another source 

indicates that the claimant has 

voluntarily left work. 

Completion of Form UI–45 is required 

to obtain or retain benefits. One 

response is received from each 

respondent. 

Previous Requests for Comments: The 

RRB has already published the initial 

60-day notice (88 FR 41993 on June 28, 

2023) required by 44 U.S.C. 3506(c)(2). 

That request elicited no comments. 

Information Collection Request (ICR) 

Title: Certification Regarding Rights to 

Unemployment Benefits. 

OMB Control Number: 3220–0079. 

Form(s) submitted: UI–45. 

Type of request: Extension without 

change of a currently approved 

collection. 

Affected public: Individuals or 

households. 

Abstract: In administering the 

disqualification for the voluntary 

leaving of work provision of Section 4 

of the Railroad Unemployment 

Insurance Act, the Railroad Retirement 

Board investigates an unemployment 

claim that indicates the claimant left 

voluntarily. The certification obtains 

information needed to determine if the 

leaving was for good cause. 

Changes proposed: The RRB proposes 

no changes to Form UI–45. 

The burden estimate for the ICR is as 

follows:

2. Title and Purpose of information 

collection: Self-Employment and 

Substantial Service Questionnaire; OMB 

3220–0138. 

Section 2 of the Railroad Retirement 

Act (RRA) (45 U.S.C. 231a) provides for 

payment of annuities to qualified 

employees and their spouses. In order to 

receive an age and service annuity, 

section 2(e)(3) states that an applicant 

must stop all railroad work and give up 

any rights to return to such work. 

However, applicants are not required to 

stop nonrailroad work or selfemployment. 

The RRB considers some work 

claimed as ‘‘self-employment’’ to 

actually be employment for an 

employer. Whether the RRB classifies a 

particular activity as self-employment or 

as work for an employer depends upon 

the circumstances of each case. These
