II. Background This draft letter clarifies the NRC staff’s interpretation of Standard Technical Specification (STS) 4.2.1, ‘‘Fuel Assemblies.’’ The first part of STS 4.2.1 places limitations on the number of fuel assemblies in the reactor core, the type of fuel that can be used, the cladding material that can be used (e.g., zircaloy or ZIRLO), and requires the use of NRC-approved codes and methods for the fuel assemblies. The last sentence of STS 4.2.1 allows for the irradiation of a limited number of LTAs that have not completed representative testing if placed in nonlimiting regions of the reactor core. In the past, licensees have taken different approaches when conducting LTA campaigns. Some licensees obtained prior NRC approval by license amendments approving changes to Technical Specification (TS) 4.2.1 or exemptions from § 50.46, ‘‘Acceptance criteria for emergency core cooling systems for light-water nuclear power reactors,’’ of title 10 of the Code of Federal Regulations (10 CFR), or both, for their LTA campaigns. Other licensees conducted LTA campaigns under 10 CFR 50.59, ‘‘Changes, tests, and experiments,’’ without prior NRC approval. This draft letter to NEI clarifies the NRC’s current interpretation of when prior NRC approval is needed for LTA campaigns. This draft letter responds to concerns from stakeholders, including NEI, that there is a lack of clarity in the regulatory requirements associated with the use of LTAs. For example, concerns were raised on the preliminary positions regarding LTAs provided in a letter to NEI dated June 29, 2017, as comments, in response to the NRC’s publication of the document, ‘‘Draft Project Plan to Prepare the U.S. Nuclear Regulatory Commission to License and Regulate Accident Tolerant Fuel’’ (82 FR 60633; December 21, 2017), and in a license amendment request for Byron Station, Unit 2, dated March 8, 2018. The draft letter provides clarification on the LTA provision in STS 4.2.1; clarification on the use of approved methods for LTA campaigns; two regulatory paths for LTA campaigns; guidance on the use of NEI 96–07, Revision 1, ‘‘Guidelines for 10 CFR 50.59 Implementation,’’ with regard to LTAs; and a position that an exemption to the requirements in 10 CFR 50.46 is not needed solely for the insertion of LTAs. III. Non-Concurrence An NRC staff member did not agree with some content of the draft letter to the NEI and submitted a nonconcurrence on the draft letter. In accordance with the NRC’s nonconcurrence process, NRC management and staff worked to address the staff member’s concerns, and documentation of the non-concurrence is available in ADAMS. IV. Backfitting and Issue Finality If finalized, the letter would provide additional clarification on previous staff preliminary statements and positions regarding the use of LTAs made in a letter to NEI dated June 29, 2017. Issuance of the letter, if finalized, would not constitute backfitting as defined in 10 CFR 50.109 (the Backfit Rule) and would not otherwise be inconsistent with the issue finality provisions in 10 CFR part 52.

SUMMARY: The U.S. Nuclear Regulatory Commission (NRC) is soliciting 
public comments on a draft letter to the Nuclear Energy Institute (NEI) 
clarifying the regulatory paths for the use of lead test assemblies 
(LTAs). This draft letter would finalize the NRC staff's views on the 
preliminary positions regarding LTAs provided in a letter to NEI dated 
June 29, 2017. The NRC does not currently have consolidated regulatory 
guidance regarding the use of LTAs. Therefore, the NRC has drafted this 
letter to clarify its positions regarding the use of LTAs. These 
positions would affect light-water reactor licensees who wish to 
irradiate LTAs.

DATES: Submit comments by June 27, 2018. 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 before this 
date.

to the public or entering the comment into ADAMS.

II. Background

    This draft letter clarifies the NRC staff's interpretation of 
Standard Technical Specification (STS) 4.2.1, ``Fuel Assemblies.'' The 
first part of STS 4.2.1 places limitations on the number of fuel 
assemblies in the reactor core, the type of fuel that can be used, the 
cladding material that can be used (e.g., zircaloy or ZIRLO), and 
requires the use of NRC-approved codes and methods for the fuel 
assemblies. The last sentence of STS 4.2.1 allows for the irradiation 
of a limited number of LTAs that have not completed representative 
testing if placed in nonlimiting regions of the reactor core.
    In the past, licensees have taken different approaches when 
conducting LTA campaigns. Some licensees obtained prior NRC approval by 
license amendments approving changes to Technical Specification (TS) 
4.2.1 or exemptions from Sec.  50.46, ``Acceptance criteria for 
emergency core cooling systems for light-water nuclear power 
reactors,'' of title 10 of the Code of Federal Regulations (10 CFR), or 
both, for their LTA campaigns. Other licensees conducted LTA campaigns 
under 10 CFR 50.59, ``Changes, tests, and experiments,'' without prior 
NRC approval. This draft letter to NEI clarifies the NRC's current 
interpretation of when prior NRC approval is needed for LTA campaigns. 
This draft letter responds to concerns from stakeholders, including 
NEI, that there is a lack of clarity in the regulatory requirements 
associated with the use of LTAs. For example, concerns were raised on 
the preliminary positions regarding LTAs provided in a letter to NEI 
dated June 29, 2017, as comments, in response to the NRC's publication 
of the document, ``Draft Project Plan to Prepare the U.S. Nuclear 
Regulatory Commission to License and Regulate Accident Tolerant Fuel'' 
(82 FR 60633; December 21, 2017), and in a license amendment request 
for Byron Station, Unit 2, dated March 8, 2018.
    The draft letter provides clarification on the LTA provision in STS 
4.2.1; clarification on the use of approved methods for LTA campaigns; 
two regulatory paths for LTA campaigns; guidance on the use of NEI 96-
07, Revision 1, ``Guidelines for 10 CFR 50.59 Implementation,'' with 
regard to LTAs; and a position that an exemption to the requirements in 
10 CFR 50.46 is not needed solely for the insertion of LTAs.

III. Non-Concurrence

    An NRC staff member did not agree with some content of the draft 
letter to the NEI and submitted a non-concurrence on the draft letter. 
In accordance with the NRC's non-concurrence process, NRC management 
and staff worked to address the staff member's concerns, and 
documentation of the non-concurrence is available in ADAMS.

IV. Backfitting and Issue Finality

    If finalized, the letter would provide additional clarification on 
previous staff preliminary statements and positions regarding the use 
of LTAs made in a letter to NEI dated June 29, 2017. Issuance of the 
letter, if finalized, would not constitute backfitting as defined in 10 
CFR 50.109 (the Backfit Rule) and would not otherwise be inconsistent 
with the issue finality provisions in 10 CFR part 52. The NRC has no 
current intention to impose the positions described in the draft letter 
on holders of current operating licenses or combined licenses.
