SUPPLEMENTARY INFORMATION: 

I. Introduction

    The NRC is considering issuance of an amendment to Facility 
Operating License No. NPF-62, issued to Clinton Power Station, Unit 1, 
located in DeWitt County, Illinois. The proposed amendment proposes a 
one-time extension from 72 hours to 7 days of the technical 
specification (TS) completion time [CT] associated with the Division 2 
(Div. 2) Shutdown Service Water (SX) Subsystem in support maintenance 
activities.
    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.
    The NRC has made a proposed determination that the license 
amendment request involves no significant hazards consideration. Under 
the NRC's regulations in Sec.  50.92 of Title 10 of the Code of Federal 
Regulations (10 CFR), 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 no significant hazards consideration, which is presented below:

    1. Does the proposed change involve a significant increase in 
the probability or consequences of an accident previously evaluated?
    Response: No.
    The proposed one-time change to the CT for CPS TS 3.7.1 will not 
increase the probability of an accident since it will only extend 
the time period that one SX subsystem can be out of service. The 
extension of the time duration that one SX subsystem is out of 
service has no direct physical impact on the plant. The proposed 
inoperable SX subsystem is normally in a standby mode while CPS is 
in Mode 1, 2, or 3 and is not directly supporting plant operation. 
Therefore, it can have no impact on the plant that would make an 
accident more likely to occur due to its inoperability. The proposed 
change does not adversely affect accident initiators or precursors, 
nor does it alter the design assumptions, conditions, or 
configuration of the facility or the manner in which the plant is 
operated and maintained.
    The previously analyzed accidents are initiated by the failure 
of plant structures, systems, or components. The SX system is not 
considered an initiator for any of these previously analyzed events. 
The proposed

[[Page 56499]]

change does not have a detrimental impact on the integrity of any 
plant structure, system, or component that initiates an analyzed 
event. No active or passive failure mechanisms that could lead to an 
accident are affected. The proposed change will not alter the 
operation of, or otherwise increase the failure probability of any 
plant equipment that initiates an analyzed accident. Therefore, the 
proposed change does not involve a significant increase in the 
probability of an accident previously evaluated.
    The proposed change does not alter or prevent the ability of 
structures, systems, and components (SSCs) from performing their 
intended function to mitigate the consequences of an initiating 
event within the assumed acceptance limits. The proposed change does 
not require any physical change to any plant SSCs nor does it 
require any change in systems or plant operations. The proposed 
onetime increase in the CT is consistent with the philosophy of the 
current TS LCO which allows one SX subsystem to be inoperable for 72 
hours. This change only extends the 72 hour CT to 7 days which has 
been shown to be acceptable from a risk perspective. The minimum 
equipment required to mitigate the consequences of an accident and/
or safely shut down the plant will be Operable or available during 
the extended CT. The proposed change is consistent with the safety 
analysis assumptions and resultant consequences. Based on the above, 
the proposed change does not involve a significant increase in the 
consequences of 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 changes do not involve the use or installation of 
new equipment and the currently installed equipment will not be 
operated in a new or different manner. No new or different system 
interactions are created and no new processes are introduced. The 
proposed changes will not introduce any new failure mechanisms, 
malfunctions, or accident initiators not already considered in the 
design and licensing bases. Based on this evaluation, the proposed 
change does not create the possibility of a new or different kind of 
accident from any accident previously evaluated.
    Therefore, the proposed change does not create the possibility 
of a new or different kind of accident from any previously 
evaluated.
    3. Does the proposed change involve a significant reduction in a 
margin of safety?
    Response: No.
    The proposed change does not alter any existing setpoints at 
which protective actions are initiated and no new setpoints or 
protective actions are introduced. The design and operation of the 
SX system remains unchanged. The risk associated with the proposed 
increase in the time an SX pump is allowed to be inoperable was 
evaluated using the risk-informed processes described in RG 1.174 
and RG 1.177. The risk was shown to be acceptable. Based on this 
evaluation, 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, it appears that 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 No Significant Hazards 
Consideration.
    The NRC is seeking public comments on this proposed determination 
that the license amendment request involves no significant hazards 
consideration. 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 amendment until the 
expiration of 60 days after the date of publication of this notice. The 
Commission may issue the license amendment before expiration of the 60-
day notice period if the Commission concludes the amendment involves no 
significant hazards consideration. In addition, the Commission may 
issue the amendment prior to the expiration of the 30-day comment 
period should 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. Should the Commission take action 
prior to the expiration of either the comment period or the notice 
period, it will publish in the Federal Register a notice of issuance. 
Should the Commission make a final No Significant Hazards Consideration 
Determination, any hearing will take place after issuance. The 
Commission expects that the need to take this action will occur very 
infrequently.

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

    Within 60 days after the date of publication of this Federal 
Register notice, any person whose interest may be affected by this 
proceeding and who desires to participate as a party in the proceeding 
must file a written request for hearing or a petition for leave to 
intervene specifying the contentions which the person seeks to have 
litigated in the hearing with respect to the license amendment request. 
Requests for hearing and petitions for leave to intervene shall be 
filed in accordance with the NRC's ``Agency Rules of Practice and 
Procedure'' in 10 CFR part 2. Interested person(s) should consult a 
current copy of 10 CFR 2.309, which is available at the NRC's PDR. The 
NRC's regulations are accessible electronically from the NRC Library on 
the NRC's Web site at https://www.nrc.gov/reading-rm/doc-collections/cfr/.
    As required by 10 CFR 2.309, a request for hearing or petition for 
leave to intervene must set forth with particularity the interest of 
the petitioner in the proceeding and how that interest may be affected 
by the results of the proceeding. The hearing request or petition must 
specifically explain the reasons why intervention should be permitted, 
with particular reference to the following general requirements: (1) 
The name, address, and telephone number of the requestor or petitioner; 
(2) the nature of the requestor's/petitioner's right under the Act to 
be made a party to the proceeding; (3) the nature and extent of the 
requestor's/petitioner's property, financial, or other interest in the 
proceeding; and (4) the possible effect of any decision or order which 
may be entered in the proceeding on the requestor's/petitioner's 
interest. The hearing request or petition must also include the 
specific contentions that the requestor/petitioner seeks to have 
litigated at the proceeding.
    For each contention, the requestor/petitioner must provide a 
specific statement of the issue of law or fact to be raised or 
controverted, as well as a brief explanation of the basis for the 
contention. Additionally, the requestor/petitioner must demonstrate 
that the issue raised by each contention is within the scope of the 
proceeding and is material to the findings that the NRC must make to 
support the granting of a license amendment in response to the 
application. The hearing request or petition must also include a 
concise statement of the alleged facts or expert opinion that support 
the contention and on which the requestor/petitioner intends to rely at 
the hearing, together with references to those specific sources and 
documents. The hearing request or petition must provide sufficient 
information to show that a genuine dispute exists with the applicant on 
a material issue of law or fact, including references to specific 
portions of the application for amendment that the petitioner disputes 
and the supporting reasons for each dispute. If the requestor/
petitioner believes that the application for amendment fails to contain 
information on a relevant matter as required by law, the requestor/
petitioner must identify each failure and the supporting reasons for 
the requestor's/petitioner's belief. Each contention must be one which, 
if proven, would entitle the requestor/

[[Page 56500]]

petitioner to relief. A requestor/petitioner who does not satisfy these 
requirements for at least one contention will not be permitted to 
participate as a party.
    Those permitted to intervene become parties to the proceeding, 
subject to any limitations in the order granting leave to intervene, 
and have the opportunity to participate fully in the conduct of the 
hearing with respect to resolution of that person's admitted 
contentions, including the opportunity to present evidence and to 
submit a cross-examination plan for cross-examination of witnesses, 
consistent with NRC regulations, policies, and procedures. The Atomic 
Safety and Licensing Board will set the time and place for any 
prehearing conferences and evidentiary hearings, and the appropriate 
notices will be provided.
    Hearing requests or petitions for leave to intervene must be filed 
no later than 60 days from the date of publication of this notice. 
Requests for hearing, petitions for leave to intervene, and motions for 
leave to file new or amended contentions that are filed after the 60-
day 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)-(iii).
    If a hearing is requested, the Commission will make a final 
determination on the issue of no significant hazards consideration. The 
final determination will serve to decide when the hearing is held. If 
the final determination is that the 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 held 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 any 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.

III. Electronic Submissions (E-Filing)

    All documents filed in NRC adjudicatory proceedings, including a 
request for hearing, a petition for leave to intervene, any motion or 
other document filed in the proceeding prior to the submission of a 
request for hearing or petition to intervene, and documents filed by 
interested governmental entities participating under 10 CFR 2.315(c), 
must be filed in accordance with the NRC's E-Filing rule (72 FR 49139; 
August 28, 2007). 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. Participants may not 
submit paper copies of their filings unless they seek an exemption in 
accordance with the procedures described below.
    To comply with the procedural requirements of E-Filing, at least 
ten 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 request (1) a digital 
identification (ID) certificate, which allows the participant (or its 
counsel or representative) to digitally sign documents and access the 
E-Submittal server for any proceeding in which it is participating; and 
(2) advise the Secretary that the participant will be submitting a 
request or petition for hearing (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 hearing in this 
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 Web site at https://www.nrc.gov/site-help/e-submittals/getting-started.html. System requirements for accessing 
the E-Submittal server are detailed in the NRC's ``Guidance for 
Electronic Submission,'' which is available on the agency's public Web 
site at https://www.nrc.gov/site-help/e-submittals.html. Participants 
may attempt to use other software not listed on the Web site, but 
should note that the NRC's E-Filing system does not support unlisted 
software, and the NRC Meta System Help Desk will not be able to offer 
assistance in using unlisted software.
    If a participant is electronically submitting a document to the NRC 
in accordance with the E-Filing rule, the participant must file the 
document using the NRC's online, Web-based submission form. In order to 
serve documents through the Electronic Information Exchange System, 
users will be required to install a Web browser plug-in from the NRC's 
Web site. Further information on the Web-based submission form, 
including the installation of the Web browser plug-in, is available on 
the NRC's public Web site at https://www.nrc.gov/site-help/e-submittals.html.
    Once a participant has obtained a digital ID certificate and a 
docket has been created, the participant can then submit a request for 
hearing or petition for leave to intervene. Submissions should be in 
Portable Document Format (PDF) in accordance with NRC guidance 
available on the NRC's public Web site at https://www.nrc.gov/site-help/e-submittals.html. A filing is considered complete at the time the 
documents are 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. Eastern Time on the due date. Upon receipt of 
a transmission, the E-Filing system time-stamps the document and sends 
the submitter an email notice confirming receipt of the document. The 
E-Filing system also distributes an email notice 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 
documents on those participants separately. Therefore, applicants and 
other participants (or their counsel or representative) must apply for 
and receive a digital ID certificate before a hearing request/petition 
to intervene is filed so that they can obtain access to the document 
via the E-Filing system.
    A person filing electronically using the NRC's adjudicatory E-
Filing system may seek assistance by contacting the NRC Meta System 
Help Desk through the ``Contact Us'' link located on the NRC's public 
Web site at 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 Meta System Help Desk is available between 8 a.m. and 8 p.m., 
Eastern Time, Monday through Friday, excluding government holidays.
    Participants who believe that they have a 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 
requesting authorization to continue to submit documents in paper 
format. Such filings must be submitted by: (1) First class mail 
addressed to the Office of the Secretary of the Commission, U.S. 
Nuclear Regulatory Commission, Washington, DC 20555-0001, Attention: 
Rulemaking and Adjudications Staff; or (2) courier, express mail, or 
expedited delivery service to the Office of the Secretary, Sixteenth 
Floor, One White Flint North,

[[Page 56501]]

11555 Rockville Pike, Rockville, Maryland, 20852, Attention: Rulemaking 
and Adjudications Staff. Participants filing a document in this manner 
are responsible for serving the document on all other participants. 
Filing is considered complete by first-class mail as of the time of 
deposit in the mail, or by courier, express mail, or expedited delivery 
service upon depositing the document with the provider of the service. 
A presiding officer, having granted an exemption request from using E-
Filing, may require a participant or party to use E-Filing if the 
presiding officer subsequently determines that the reason for granting 
the exemption from use of E-Filing no longer exists.
    Documents submitted in adjudicatory proceedings will appear in the 
NRC's electronic hearing docket which is available to the public at 
https://ehd1.nrc.gov/ehd/, unless excluded pursuant to an order of the 
Commission, or the presiding officer. Participants are requested not to 
include personal privacy information, such as social security numbers, 
home addresses, or home phone numbers in their filings, unless an NRC 
regulation or other law requires submission of such information. 
However, in some instances, a request to intervene will require 
including information on local residence in order to demonstrate a 
proximity assertion of interest in the proceeding. 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 are requested not to include copyrighted 
materials in their submission.
    Petitions for leave to intervene must be filed no later than 60 
days from the date of publication of this notice. Requests for hearing, 
petitions for leave to intervene, and motions for leave to file new or 
amended contentions that are filed after the 60-day 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)-(iii).
    For further details with respect to this action, see the 
application for license amendment dated September 11, 2015.
