NRC License Amendment Notice and Opportunity to Comment

Content

ACTION:

License amendment request; notice of opportunity to comment, request a hearing, and petition for leave to intervene; order
imposing procedures.

SUMMARY:

The U.S. Nuclear Regulatory Commission (NRC, the Commission) received, and is considering approval of, two requests to amend
operating licenses. The license amendment requests are for St. Lucie Plant, Unit No. 1 and Diablo Canyon Nuclear Power Plant,
Units 1 and 2. For each amendment request, the NRC proposes to determine that it involves no significant hazards consideration
(NSHC). Because each amendment request contains sensitive unclassified non-safeguards information (SUNSI), the NRC is issuing
an order imposing procedures to obtain access to SUNSI for contention preparation by persons who file a hearing request or
petition for leave to intervene.

DATES:

Comments must be filed by April 23, 2026. A request for a hearing or petitions for leave to intervene must be filed by May
26, 2026. Any potential party as defined in section 2.4 of title 10 of the Code of Federal Regulations (10 CFR) who believes access to SUNSI is necessary to respond to this notice must request document access by April 3, 2026.

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

Pursuant to section 189a.(1)-(2) of the Atomic Energy Act of 1954, as amended (the Act), the NRC is publishing this notice.
The Act requires the Commission to publish notice of any license amendments issued or proposed to be issued and grants the
Commission the authority to issue and make immediately effective any amendment to an operating license or combined license,
as applicable, upon a determination by the Commission that such amendment involves NSHC, notwithstanding the pendency before
the Commission of a request for a hearing from any person.

This notice includes notices of license amendments containing SUNSI.

III. Notice of Consideration of Issuance of Amendments to Facility Operating Licenses, Proposed No Significant Hazards Consideration

Determination, and Opportunity for a Hearing

The Commission has made a proposed determination that the following license amendment requests involve NSHC. Under the Commission's
regulations in 10 CFR 50.92, this means that operation of the facility in accordance with the proposed amendments would not
(1) involve a significant increase in the probability or consequences of an accident previously evaluated, or (2) create the
possibility of a new or different kind of accident from any accident previously evaluated, or (3) involve a significant reduction
in a margin of safety. The basis for this proposed determination for each amendment request is shown as follows.

The Commission is seeking public comments on these proposed NSHC determinations. Any comments received within 30 days after
the date of publication of this notice will be considered in making any final determination.

Normally, the Commission will not issue the license amendments until the expiration of 60 days after the date of publication
of this notice. The Commission may issue any of these license amendments before expiration of the 60-day period provided that
its final determination is that the amendments involve no significant hazards consideration. In addition, the Commission may
issue any of these amendments prior to the expiration of the 30-day comment period if circumstances change during the 30-day
comment period such that failure to act in a timely way would result, for example, in derating or shutdown of the facility.
If the Commission takes action on any of these amendments prior to the expiration of either the comment period or the notice
period, it will publish a notice of issuance in the
Federal Register
. If the Commission makes a final no significant hazards consideration determination for any of these license amendments,
any hearing on those amendments will take place after issuance. The Commission expects that the need to take this action will
occur very infrequently.

A. Opportunity To Request a Hearing and Petition for Leave To Intervene

Within 60 days after the date of publication of this notice, any person (petitioner) whose interest may be affected by any
of these actions may file a request for a hearing and petition for leave to intervene (petition) with respect to that action.
Petitions shall be filed in accordance with the Commission's “Agency Rules of Practice and Procedure” in 10 CFR part 2. Interested
persons should consult 10 CFR 2.309. If a petition is filed, the Commission or a presiding officer will rule on the petition
and, if appropriate, a notice of a hearing will be issued.

Petitions must be filed no later than 60 days from the date of publication of this notice in accordance with the filing instructions
in the “Electronic Submissions (E-Filing)” section of this document. Petitions and motions for leave to file new or amended
contentions that are filed after the deadline will not be entertained absent a determination by the presiding officer that
the filing demonstrates good cause by satisfying the three factors in 10 CFR 2.309(c)(1)(i) through (iii).

If a hearing is requested, and the Commission has not made a final determination on the issue of no significant hazards consideration,
the Commission will make a final determination on the issue of no significant hazards consideration, which will serve to establish
when the hearing is held. If the final determination is that the license amendment request involves no significant hazards
consideration, the Commission may issue the amendment and make it immediately effective, notwithstanding the request for a
hearing. Any hearing would take place after issuance of the amendment. If the final determination is that the license amendment
request involves a significant hazards consideration, then any hearing held would take place before the issuance of the amendment
unless the Commission finds an imminent danger to the health or safety of the public, in which case it will issue an appropriate
order or rule under 10 CFR part 2.

A State, local governmental body, Federally recognized Indian Tribe, or designated agency thereof, may submit a petition to
the Commission to participate as a party under 10 CFR 2.309(h) no later than 60 days from the date of publication of this
notice. Alternatively, a State, local governmental body, Federally recognized Indian Tribe, or designated agency thereof,
may participate as a non-party under 10 CFR 2.315(c).

For information about filing a petition and about participation by a person not a party under 10 CFR 2.315, see ADAMS Accession
No. ML20340A053 (https://adamswebsearch2.nrc.gov/webSearch2/main.jsp?AccessionNumber=ML20340A053) and the NRC's public website (https://www.nrc.gov/about-nrc/regulatory/adjudicatory/hearing.html#participate).

B. Electronic Submissions (E-Filing)

All documents filed in NRC adjudicatory proceedings, including documents filed by an interested State, local governmental
body, Federally recognized Indian Tribe, or designated agency thereof that requests to participate under 10 CFR 2.315(c),
must be filed in accordance with 10 CFR 2.302. The E-Filing process requires participants to submit and serve all adjudicatory
documents over the internet, or in some cases, to mail copies on electronic storage media, unless an exemption permitting
an alternative filing method, as further discussed, is granted. Detailed guidance on electronic submissions is located in
the “Guidance for Electronic Submissions to the NRC” (ADAMS Accession No. ML13031A056), and on the NRC's public website (https://www.nrc.gov/site-help/e-submittals.html).

To comply with the procedural requirements of E-Filing, at least 10 days prior to the filing deadline, the participant should
contact the Office of the Secretary by email at Hearing.Docket@nrc.gov, or by telephone at 301-415-1677, to: (1) request a digital identification (ID) certificate which allows the participant (or
their counsel or representative) to digitally sign submissions and access the E-Filing system for any proceeding in which
it is participating; and (2) advise the Secretary that the participant will be submitting a petition or other adjudicatory
document (even in instances in which the participant, or their counsel or representative, already holds an NRC-issued digital
ID certificate). Based upon this information, the Secretary will establish an electronic docket for the proceeding if the
Secretary has not already established an electronic docket.

Information about applying for a digital ID certificate is available on the NRC's public website (https://www.nrc.gov/site-help/e-submittals/getting-started.html). After a digital ID certificate is obtained and a docket is created, the participant must submit adjudicatory documents
in the Portable Document Format. Guidance on submissions is available on the NRC's public website (https://www.nrc.gov/site-help/electronic-sub-ref-mat.html). A filing is considered complete at the time the document is submitted through the NRC's E-Filing system. To be timely,
an electronic filing must be submitted to the E-Filing system no later than 11:59 p.m. ET on the due date. Upon receipt of
a transmission, the E-Filing system time-stamps the document and sends the submitter an email confirming receipt of the document.
The E-Filing system also distributes an email that provides access to the document to the NRC's Office of the General Counsel
and any others who have advised the Office of the Secretary that they wish to participate in the proceeding, so that the filer
need not serve the document on those participants separately. Therefore, applicants and other participants (or their counsel
or representative) must apply for and receive a digital ID certificate before adjudicatory documents are filed in order to
obtain access to the documents via the E-Filing system.

A person filing electronically using the NRC's adjudicatory E-Filing system may seek assistance by contacting the NRC's Electronic
Filing Help Desk through the “Contact Us” link located on the NRC's public website (https://www.nrc.gov/site-help/e-submittals.html), by email to MSHD.Resource@nrc.gov, or by a toll-free call at 1-866-672-7640. The NRC Electronic Filing Help Desk is available between 9 a.m. and 6 p.m., ET,
Monday through Friday, except Federal holidays.

Participants who believe that they have good cause for not submitting documents electronically must file an exemption request,
in accordance with 10 CFR 2.302(g), with their initial paper filing stating why there is good cause for not filing electronically
and requesting authorization to continue to submit documents in paper format. Such filings must be submitted in accordance
with 10 CFR 2.302(b)-(d). Participants filing adjudicatory documents in this manner are responsible for serving their documents
on all other participants. Participants granted an exemption under 10 CFR 2.302(g)(2) must still meet the electronic formatting
requirement in 10 CFR 2.302(g)(1), unless the participant also seeks and is granted an exemption from 10 CFR 2.302(g)(1).

Documents submitted in adjudicatory proceedings will appear in the NRC's electronic hearing docket, which is publicly available
on the NRC's public website (https://adams.nrc.gov/ehd), unless otherwise excluded pursuant to an order of the presiding officer. If you do not have an NRC-issued digital ID certificate
as previously described, click “cancel” when the link requests certificates and you will be automatically directed to the
NRC's electronic hearing docket where you will be able to access any publicly available documents in a particular hearing
docket. Participants are requested not to include personal privacy information such as social security numbers, home addresses,
or personal phone numbers in their filings unless an NRC regulation or other law requires submission of such information.
With respect to copyrighted works, except for limited excerpts that serve the purpose of the adjudicatory filings and would
constitute a Fair Use application, participants should not include copyrighted materials in their submission.

The following table provides the plant name, docket numbers, date of application, ADAMS accession number, and location in
the application of the licensee's proposed NSHC determination. For further details with respect to these license amendment
applications, see the applications for amendment, publicly available portions of which is available for public inspection

Order Imposing Procedures for Access to Sensitive Unclassified Non-Safeguards Information for Contention Preparation

Florida Power & Light Company; St. Lucie Plant, Unit No. 1; St. Lucie County, FL; Pacific Gas and Electric Company; Diablo

Canyon Nuclear Power Plant, Units 1 and 2; San Luis Obispo County, CA

A. This Order contains instructions regarding how potential parties to this proceeding may request access to documents containing
Sensitive Unclassified Non-Safeguards Information (SUNSI).

B. Within 10 days after publication of this notice of hearing or opportunity for hearing, any potential party who believes
access to SUNSI is necessary to respond to this notice may request access to SUNSI. A “potential party” is any person who
intends to participate as a party by demonstrating standing and filing an admissible contention under 10 CFR 2.309. Requests
for access to SUNSI submitted later than 10 days after publication of this notice will not be considered absent a showing
of good cause for the late filing, addressing why the request could not have been filed earlier.

C. The requestor shall submit a letter requesting permission to access SUNSI to the Office of the Secretary, U.S. Nuclear
Regulatory Commission, Washington, DC 20555-0001, Attention: Rulemakings and Adjudications Staff, and provide a copy to the
Deputy General Counsel for Licensing, Hearings, and Enforcement, Office of the General Counsel, U.S. Nuclear Regulatory Commission,
Washington, DC 20555-0001. The expedited delivery or courier mail address for both offices is: U.S. Nuclear Regulatory Commission,
11555 Rockville Pike, Rockville, Maryland 20852. The email addresses for the Office of the Secretary and the Office of the
General Counsel are Hearing.Docket@nrc.gov and RidsOgcMailCenter.Resource@nrc.gov, respectively. (1) The request must include the following information:

(1) A description of the licensing action with a citation to this
Federal Register
notice;

(2) The name and address of the potential party and a description of the potential party's particularized interest that could
be harmed by the action identified in C.(1); and

(3) The identity of the individual or entity requesting access to SUNSI and the requestor's basis for the need for the information
in order to meaningfully participate in this adjudicatory proceeding. In particular, the request must explain why publicly
available versions of the information requested would not be sufficient to provide the basis and specificity for a proffered
contention.

D. Based on an evaluation of the information submitted under paragraph C, the NRC staff will determine within 10 days of receipt
of the request whether:

(1) There is a reasonable basis to believe the petitioner is likely to establish standing to participate in this NRC proceeding;
and

(2) The requestor has established a legitimate need for access to SUNSI.

E. If the NRC staff determines that the requestor satisfies both D.(1) and D.(2), the NRC staff will notify the requestor
in writing that access to SUNSI has been granted. The written notification will contain instructions on how the requestor
may obtain copies of the requested documents, and any other conditions that may apply to access to those documents. These
conditions may include, but are not limited to, the signing of a Non-Disclosure Agreement

  or Affidavit, or Protective Order [(2)]() setting forth terms and conditions to prevent the unauthorized or inadvertent disclosure of SUNSI by each individual who will
  be granted access to SUNSI.

F. Filing of Contentions. Any contentions in these proceedings that are based upon the information received as a result of
the request made for SUNSI must be filed by the requestor no later than 25 days after receipt of (or access to) that information.
However, if more than 25 days remain between the petitioner's receipt of (or access to) the information and the deadline for
filing all other contentions (as established in the notice of hearing or opportunity for hearing), the petitioner may file
its SUNSI contentions by that later deadline.

G. Review of Denials of Access.

(1) If the request for access to SUNSI is denied by the NRC staff after a determination on standing and requisite need, the
NRC staff shall immediately notify the requestor in writing, briefly stating the reason or reasons for the denial.

(2) The requestor may challenge the NRC staff's adverse determination by filing a challenge within 5 days of receipt of that
determination with: (a) the presiding officer designated in this proceeding; (b) if no presiding officer has been appointed,
the Chief Administrative Judge, or if this individual is unavailable, another administrative judge, or an Administrative Law
Judge with jurisdiction pursuant to 10 CFR 2.318(a); or (c) if another officer has been designated to rule on information
access issues, with that officer.

(3) Further appeals of decisions under this paragraph must be made pursuant to 10 CFR 2.311.

H. Review of Grants of Access. A party other than the requestor may challenge an NRC staff determination granting access to
SUNSI whose release would harm that party's interest independent of the proceeding. Such a challenge must be filed within
5 days of the notification by the NRC staff of its grant of access and must be filed with: (a) the presiding officer designated
in this proceeding; (b) if no presiding officer has been appointed, the Chief Administrative Judge, or if this individual
is unavailable, another administrative judge, or an Administrative Law Judge with jurisdiction pursuant to 10 CFR 2.318(a);
or (c) if another officer has been designated to rule on information access issues, with that officer.

If challenges to the NRC staff determinations are filed, these procedures give way to the normal process for litigating disputes
concerning access to information. The availability of interlocutory review by the Commission of orders ruling on such NRC
staff determinations (whether granting or denying access) is governed by 10 CFR 2.311. (3)

I. The Commission expects that the NRC staff and presiding officers (and any other reviewing officers) will consider and resolve
requests for access to SUNSI, and motions for protective orders, in a timely fashion in order to minimize any unnecessary
delays in identifying those petitioners who have standing and who have propounded contentions meeting the specificity and
basis requirements in 10 CFR part 2. The attachment to this Order summarizes the general target schedule for processing and
resolving requests under these procedures.

It is so ordered.

Dated: March 20, 2026. For the Nuclear Regulatory Commission.

Tomas Herrera, Acting Secretary of the Commission.

Footnotes

(1) While a request for hearing or petition to intervene in this proceeding must comply with the filing requirements of the NRC's
“E-Filing Rule,” the initial request to access SUNSI under these procedures should be submitted as described in this paragraph.

(2) Any motion for Protective Order or proposed Non-Disclosure Affidavit or Agreement for SUNSI must be filed with the presiding
officer or the Chief Administrative Judge if the presiding officer has not yet been designated, within 30 days of the deadline
for the receipt of the written access request.

(3) Requestors should note that the filing requirements of the NRC's E-Filing Rule (72 FR 49139; August 28, 2007, as amended
at 77 FR 46562; August 3, 2012, 78 FR 34247, June 7, 2013) apply to appeals of NRC staff determinations (because they must
be served on a presiding officer or the Commission, as applicable), but not to the initial SUNSI request submitted to the
NRC staff under these procedures.
