SUPPLEMENTARY INFORMATION: 

I. Background

As part of its review of non-lightwater reactor applications, the NRC 

determines whether materials proposed 

to be used will allow components to 

fulfill design requirements for the 

design life, or that adequate surveillance 

and monitoring programs are in place. 

The NRC regulations in part 50 and part 

52 of title 10 of the Code of Federal 

Regulations (10 CFR) include 

requirements for material qualification 

and performance monitoring. The NRC 

endorsed American Society of 

Mechanical Engineers (ASME) Code 

Section III, Division 5, ‘‘High 

Temperature Reactors’’ (Section III–5), 

with conditions, in Revision 2 of 

Regulatory Guide 1.87, ‘‘Acceptability of 

ASME Code, Section III, Division 5, 

‘High Temperature Reactors,’ ’’ (ADAMS 

Accession No. ML22101A263). 

II. Discussion

The purpose of this ISG, ‘‘Material

Compatibility for Non-Light Water 

Reactors, DANU–ISG–2023–01’’ 

(ADAMS Accession No. ML23188A178), 

is to aid the NRC staff reviewing nonlight-water reactor applications for a 

construction permit or operating license 

under 10 CFR part 50 or for a design 

certification, combined license,

8066 Federal Register / Vol. 89, No. 25 / Tuesday, February 6, 2024 / Rules and Regulations 

standard design approval, or 

manufacturing license under 10 CFR 

part 52 that propose to use materials 

allowed under Section III–5. Section III– 

5 specifies the mechanical properties 

and allowable stresses to be used for 

design of components in high 

temperature reactors. Because Section 

III–5 states that it does not provide 

methods to evaluate deterioration that 

may occur in service as a result of 

corrosion, mass transfer phenomena, 

radiation effects, or other material 

instabilities, this ISG identifies 

information that the NRC staff should 

consider as part of its review of a nonlight-water reactor application to review 

applicable design requirements, 

including qualification and monitoring 

programs for safety-significant 

structures, systems, and components. 

III. Additional Information 

Draft DANU–ISG–2023–01 ‘‘Material 

Compatibility for Non-Light Water 

Reactors’’ was published in the Federal 

Register for public comment on March 

7, 2023, (88 FR 14186) with a 60-day 

comment period. The NRC received 

fifteen public comments from private 

citizens and industry organizations. The 

NRC staff’s evaluation and resolution of 

the public comments are documented in 

Appendix A to the ISG in ADAMS 

under Accession No. ML23188A178. 

IV. Congressional Review Act 

DANU–ISG–2023–01 ‘‘Material 

Compatibility for Non-Light Water 

Reactors’’ is a rule as defined in the 

Congressional Review Act (5 U.S.C. 

801–808). However, the Office of 

Management and Budget has not found 

it to be a major rule as defined in the 

Congressional Review Act.

[Docket No. FAA–2024–0037; Project

39–22664; AD 2024–01–52]

Airworthiness Directives; He ́licopte`res 

Guimbal Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Final rule; request for 

comments. 

SUMMARY: The FAA is superseding 

Airworthiness Directive (AD) 2023–24– 

51 which applied to all He ́licopte`res 

Guimbal Model Cabri G2 helicopters. 

AD 2023–24–51 was prompted by 

reports of a crack in the pilot cyclic 

stick base and required repetitively 

inspecting certain part-numbered pilot 

and co-pilot cyclic stick bases and, 

depending on the results, corrective 

action. AD 2023–24–51 also prohibited 

installing those pilot and co-pilot cyclic 

stick bases unless certain requirements 

were met. Since the FAA issued AD 

2023–24–51, more cracks in the cyclic 

stick bases have been reported, 

including a crack in a cyclic stick base 

that had accumulated only 700 hours 

time-in-service (TIS). This AD requires 

the same actions as AD 2023–24–51 but 

reduces the compliance time for 

performing the initial inspection. These 

actions are specified in a European 

Union Aviation Safety Agency (EASA) 

AD, which is incorporated by reference. 

The FAA previously sent this AD as an 

emergency AD to all known U.S. owners 

and operators of these helicopters. The 

FAA is issuing this AD to address the 

unsafe condition on these products. 

DATES: This AD is effective February 21, 

2024. Emergency AD 2024–01–52, 

issued on January 9, 2024, which 

contained the requirements of this 

amendment, was effective with actual 

notice. 

The Director of the Federal Register 

approved the incorporation by reference 

of certain publications listed in this AD 

as of February 21, 2024. 

The FAA must receive comments on 

this AD by March 22, 2024. 

ADDRESSES: You may send comments, 

using the procedures found in 14 CFR 

11.43 and 11.45, by any of the following 

methods: 

• Federal eRulemaking Portal: Go to 

regulations.gov. Follow the instructions
