Operational Leakage 

AGENCY: Nuclear Regulatory 

Commission. 

ACTION: Draft regulatory issue summary; 

public meeting and request for 

comment. 

SUMMARY: The U.S. Nuclear Regulatory 

Commission (NRC) is seeking public 

comment on a draft regulatory issue 

summary (RIS) Operational Leakage. 

The NRC staff seeks to clarify regulatory 

requirements for all licensees of boiling 

and pressurized water reactors that 

apply to operational leakage. This draft 

RIS is a clarification for the NRC 

requirements for evaluation, control, 

and treatment of operational leakage in 

systems required to be operable by plant 

technical specifications (TS). 

DATES: Submit comments by March 15, 

2022. Comments received after this date 

will be considered if it is practical to do 

so, but the Commission is able to ensure 

consideration only for comments 

received on or before this date. 

ADDRESSES: You may submit comments 

by any of the following methods; 

however, the NRC encourages electronic 

comment submission through the 

Federal Rulemaking Website:

II. Background 

This RIS is intended for all holders of 

operating licenses and combined 

licenses for nuclear power reactors, 

except those who have permanently 

ceased operations and have certified 

that fuel has been permanently removed 

from the reactor vessel. 

Operational leakage is leakage 

through a flaw in the pressure retaining 

boundary of American Society of 

Mechanical Engineers (ASME) Boiler 

and Pressure Vessel Code (BPVC) Code 

Class 1, 2 or 3 systems, structures, and 

components (SSC) discovered during 

the operational life of the nuclear power 

plant outside any ASME BPVC-required 

pressure test. The term ‘‘through-wall’’ 

describes a condition that extends from 

one surface to another surface in a 

component. If through-wall operational 

leakage is observed from an ASME 

BPVC Class 1, 2 or 3 SSC, and the 

structural integrity of the SSC must be 

established to conclude that the system 

remains operable, then the methods 

described in the provisions of the 

applicable inservice inspection 

requirements, as specified in paragraph 

50.55a(g) of title 10 of the Code of 

Federal Regulations, must be used. 

These methods require analysis in 

accordance with the original 

construction code, the implementation 

of an NRC-approved ASME BPVC Code 

Case, or Nonmandatory Appendix U of 

ASME BPVC, Section XI, to verify 

structural integrity or perform a repair/ 

replacement activity. 


lotter on DSK11XQN23PROD with PROPOSALS1
2362 Federal Register / Vol. 87, No. 10 / Friday, January 14, 2022 / Proposed Rules 

This RIS emphasizes that operational 

leakage must be addressed in the same 

manner as leakage detected during an 

ASME BPVC, Section XI, pressure test. 

That is, when operational leakage is 

found in a system that is within the 

scope of ASME BPVC, Section XI, and 

is required to be operable by plant TS, 

the component must be evaluated by the 

licensee for operability. Structural 

integrity determinations must be 

conducted in accordance with the 

applicable provisions of the original 

construction code, the ASME BPVC, 

Section XI, or otherwise addressed 

through authorized methods. This 

entails evaluation in accordance with an 

NRC-approved Code Case; the use of 

Nonmandatory Appendix U of ASME 

BPVC, Section XI; or a repair/ 

replacement activity. 

The NRC issues RISs to communicate 

with stakeholders on a broad range of 

matters. This may include 

communication and clarification of NRC 

technical or policy positions on 

regulatory matters that have not been 

communicated to or are not broadly 

understood by the nuclear industry. 

As noted in ‘‘Relocation of Regulatory 

Issue Summary Notices in the Federal 

Register’’ (May 8, 2018, 83 FR 20858), 

this document is being published in the 

Proposed Rules section of the Federal 

Register to comply with publication 

requirements under 1 CFR chapter I. 

II. Proposed Action 

The NRC is requesting public 

comments on the draft RIS. The NRC 

plans to hold a public meeting to 

discuss this RIS and the issues 

associated with it. Additional details 

regarding the meeting will be posted at 

least 10 days prior to the public meeting 

on the NRC’s Public Meeting Schedule 

website at https://www.nrc.gov/publicinvolve/public-meetings/index.cfm. All 

comments that are to receive 

consideration in the final RIS must still 

be submitted electronically or in writing 

as indicated in the ADDRESSES section of 

this document. 

The NRC staff will make a final 

determination regarding issuance of the 

RIS after it considers any public 

comments received in response to this 

request.

Identifier MCAI–2021–00986–R] 

RIN 2120–AA64 

Airworthiness Directives; Bell Textron 

Canada Limited (Type Certificate 

Previously Held by Bell Helicopter 

Textron Canada Limited) Helicopters 

AGENCY: Federal Aviation 

Administration (FAA), DOT. 

ACTION: Notice of proposed rulemaking 

(NPRM). 

SUMMARY: The FAA proposes to 

supersede Airworthiness Directive (AD) 

2020–20–06, which applies to certain 

Bell Helicopter Textron Canada Limited 

(now Bell Textron Canada Limited) 

Model 429 helicopters. AD 2020–20–06 

requires repetitive inspections of certain 

cyclic and collective assembly bearings. 

Since the FAA issued AD 2020–20–06, 

the collective and cyclic bellcrank 

assemblies have been upgraded with 

corrosion resistant steel bearings. This 

proposed AD would retain some of the 

requirements of AD 2020–20–06 and 

depending on the inspection results, 

would require removing certain parts 

from service and installing the upgraded 

cyclic and collective bellcrank 

assemblies. This proposed AD would 

also require installing the upgraded 

collective and cyclic bellcrank 

assemblies on certain helicopters if not 

already installed, and would prohibit 

installing certain bellcrank assemblies. 

The FAA is proposing this AD to 

address the unsafe condition on these 

products. 

DATES: The FAA must receive comments 

on this proposed AD by February 28, 

2022. 

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 

https://www.regulations.gov. Follow the 

instructions for submitting comments.
