II. Introduction 

The NRC is considering issuance of an 

amendment to Facility Operating 

License No. DPR–82, issued to PG&E, 

for operation of Diablo Canyon, Unit 2, 

located in San Luis Obispo County, 

California. 

The proposed amendment would 

revise TS 3.7.8, ‘‘Auxiliary Saltwater 

(ASW) System,’’ to provide a revised TS 

3.7.8 Condition A Note to allow a onetime completion time (CT) of 144 hours 

to replace the ASW System Pump 2–2 

motor during Cycle 24 for Diablo 

Canyon, Unit 2. 

Pursuant to the requirements of 

sections 50.91 and 50.92 of Title 10 of 

the Code of Federal Regulations (10 

CFR), the licensee requested approval of 

the amendment under exigent 

circumstances. The need to replace the 

ASW Pump 2–2 motor occurred on an 

emergent basis due to indication of a 

potential degraded motor bearing. The 

ASW Pump 2–2 motor is currently 

OPERABLE but trends in bearing 

performance indicate that 

OPERABILITY could be impacted prior 

to the next scheduled Unit 2 refueling 

outage in April 2023. In order to 

maintain high plant safety, PG&E 

currently plans to begin replacement of 

the ASW Pump 2–2 motor the week of 

December 11, 2023. The circumstances 

requiring this exigent amendment 

request could not reasonably have been 

avoided. Oil samples collected from 

ASW pump 2–2 in January 2023 up 

until August 21, 2023, were within 

acceptance limits. On October 23, 2023, 

the ASW Pump 2–2 oil sample visually 

exhibited further discoloration 

compared to the sample collected on 

August 21, 2023, indicating that 

degradation had continued. As a result 

of the indication of a potential degraded 

ASW Pump 2–2 motor bearing on 

October 23, 2023, the associated 

analysis on October 27, 2023, indicating 

a further step change increase in 

particulate count, and as a prudent 

measure to maintain high reliability of 

the ASW pump, PG&E currently plans 

to begin replacement of the ASW Pump 

2–2 motor on the week of December 11, 

2023. The replacement of this motor 

will have no impact on the unit

81444 Federal Register / Vol. 88, No. 224 / Wednesday, November 22, 2023 / Notices 

electrical load or electrical distribution 

systems. 

Before any issuance of the proposed 

license amendment, the NRC will need 

to make the findings required by the 

Atomic Energy Act of 1954, as amended 

(the Act), and NRC’s regulations. 

Pursuant to 10 CFR 50.91(a)(6) for 

amendments to be granted under 

exigent circumstances, the NRC has 

made a proposed determination that the 

license amendment request involves no 

significant hazards consideration 

(NSHC). Under the NRC’s regulations in 

10 CFR 50.92, this means that operation 

of the facility in accordance with the 

proposed amendment 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. As required by 10 CFR 

50.91(a), the licensee has provided its 

analysis of the issue of NSHC, which is 

presented as follows: 

1. Does the proposed change involve a 

significant increase in the probability or 

consequences of an accident previously 

evaluated? 

Response: No. 

The proposed change to the requirements 

in TS 3.7.8, ‘‘Auxiliary Saltwater (ASW) 

System’’ Condition A will allow a one-time 

Completion Time of 144-hours during Unit 2 

Cycle 24 for Auxiliary Saltwater System 

(ASW) Pump 2–2 to support the emergent 

replacement of the pump motor. The ASW 

system is not an initiator of any UFSAR 

Chapter 6 or 15 design basis accident or 

event, and therefore, the proposed change 

does not increase the probability of any 

accident previously evaluated. The ASW 

system is used to supply cooling water to 

respond to accidents that have been 

previously evaluated. The proposed change 

affects only the time allowed for an ASW 

system train to be inoperable and does not 

affect the design of the ASW system. With 

the change to TS 3.7.8, adequate ASW 

continues to be provided to perform the heat 

removal function for accidents previously 

evaluated and there is no significant impact 

on accident consequences. The proposed 

change does not significantly change how the 

plant would mitigate an accident previously 

evaluated. 

Therefore, the proposed change does not 

involve a significant increase in the 

probability or consequences of an accident 

previously evaluated. 

2. Does the proposed change create the 

possibility of a new or different kind of 

accident from any accident previously 

evaluated? 

Response: No. 

The proposed change does not result in a 

change in the manner in which the ASW 

system provides plant protection. The ASW 

system will continue to perform the function 

of heat removal while in the proposed 

revised TS 3.7.8 Condition A. The change 

does not involve a physical alteration of the 

plant that impacts the capability of the ASW 

system to perform its design function. 

Therefore, the proposed change does not 

create the possibility of a new or different 

accident from any accident previously 

evaluated. 

3. Does the proposed change involve a 

significant reduction in a margin of safety? 

Response: No. 

The proposed change does not alter the 

manner in which safety limits, limiting safety 

system settings, or limiting conditions for 

operation are determined. The safety analysis 

acceptance criteria are not impacted by this 

change. The proposed change will not result 

in plant operation in a configuration outside 

the existing design basis since TS 3.7.8 

Condition A already allows one train of the 

ASW system to be inoperable. 

Therefore, the proposed change does not 

involve a significant reduction in a margin of 

safety. 

The NRC staff has reviewed the 

licensee’s analysis and, based on this 

review, the three standards of 10 CFR 

50.92(c) are satisfied. Therefore, the 

NRC staff proposes to determine that the 

license amendment request involves a 

NSHC. In accordance with 10 CFR 

50.91(a)(6), where the Commission finds 

that exigent circumstances exist, in that 

a licensee and the Commission must act 

quickly and that time does not permit 

the Commission to publish a Federal 

Register notice allowing 30 days for 

prior public comment, and it also 

determines that the amendment 

involves NSHCs, it can issue a Federal 

Register notice providing notice of an 

opportunity for hearing and allowing at 

least two weeks from the date of the 

notice for prior public comment. 

Therefore, in accordance with 10 CFR 

50.91(a)(6)(i)(A), the NRC staff is 

providing a 14-day notice period for 

public comment. 

The NRC is seeking public comments 

on this proposed determination that the 

license amendment request involves 

NSHC. Any comments received within 

14 days after the date of publication of 

this notice will be considered in making 

any final determination. 

Normally, the Commission will not 

issue the amendment until the 

expiration of the 14-day notice period. 

However, if circumstances change 

during the notice period, such that 

failure to act in a timely way would 

result, for example, in derating or 

shutdown of the facility, the 

Commission may issue the license 

amendment before the expiration of the 

14-day notice period, provided that its 

final determination is that the 

amendment involves NSHC. The final 

determination will consider all public 

and State comments received. If the 

Commission takes this action, it will 

publish in the Federal Register a notice 

of issuance. The Commission expects 

that the need to take this action will 

occur very infrequently. 

III. 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 this action may file a request 

for a hearing and petition for leave to 

intervene (petition) with respect to the 

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 a current copy 

of 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 NHSC, the 

Commission will make a final 

determination on the issue of NSHC, 

which will serve to establish when the 

hearing is held. If the final 

determination is that the amendment 

request involves NHSC, 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 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 agency 


khammond on DSKJM1Z7X2PROD with NOTICES
Federal Register / Vol. 88, No. 224 / Wednesday, November 22, 2023 / Notices 81445 

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?Accession

Number=ML20340A053) and on the 

NRC’s public website at https:// 

www.nrc.gov/about-nrc/regulatory/ 

adjudicatory/hearing.html#participate. 

IV. 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 at 

https://www.nrc.gov/site-help/esubmittals.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 its 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 its 

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 at https://

www.nrc.gov/site-help/e-submittals/ 

getting-started.html. After a digital ID 

certificate is obtained and a docket 

created, the participant must submit 

adjudicatory documents in Portable 

Document Format. Guidance on 

submissions is available on the NRC’s 

public website at 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 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 at https:// 

www.nrc.gov/site-help/esubmittals.html, by email to 

MSHD.Resource@nrc.gov, or by a tollfree 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 at https://

adams.nrc.gov/ehd, unless excluded 

pursuant to an order of the presiding 

officer. If you do not have an NRCissued 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 dockets 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. 

For further details with respect to this 

action, see the application for license 

amendment dated November 14, 2023, 

as supplemented by letter dated 

November 16, 2023 (ADAMS Accession 

Nos. ML23319A204 and ML23320A312,
