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, E:\FR\FM\06FER1.SGM 06FER1 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).

ACTION: Final rule; request for comments. AGENCY: 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.

SUPPLEMENTARY INFORMATION: 

I. Background

    As part of its review of non-light-water 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 non-light-water reactor applications 
for a construction permit or operating license under 10 CFR part 50 or 
for a design certification, combined license,

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 non-light-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.
