## I. Introduction

The NRC is considering issuance of an amendment to Facility Operating License Nos. NPF-12 for Summer, Unit No. 1, located in Fairfield County, South Carolina.

The proposed amendment would amend the Summer, Unit No. 1, Technical Specifications (TS) SR 4.3.3.6 to allow a one-time extension of the frequency of the Core Exit Temperature Instrumentation channel calibrations from “every refueling outage” to “every 19 months.”

SR 4.3.3.6 is required to be performed on an every refueling outage frequency, the grace period for the surveillance test ends on September 28, 2018. The licensee was unable to complete SR 4.3.3.6 on June 19, 2018 due to inadequate fire watch resources. Before the test could be rescheduled, unidentified leakage was noted to be elevated on June 21, 2018. Reactor building entries were made on June 21, 2018, and determined that incore thimble B-7 was leaking around the `A' 10-path, and the leak was isolated. From the time the leak was isolated on June 21, 2018, to August 2, 2018, the station made ten reactor building entries to determine the status of the incore detector system and attempt to restore the system to operable status.

On August 7, 2018, the licensee decided not to perform dewatering of the thimbles online due to the radiological and industrial risk associated with the task. Preparations to restore the system during the upcoming refueling outage RF24, which is scheduled to begin on October 6, 2018, are ongoing. The licensee submitted this amendment request on August 24, 2018, however, due to the impracticality of restoring the surveillance capability described above the licensee revised its request to preclude a plant shutdown and submitted a supplement on the basis of exigent circumstances. By letter dated August 31, 2018, the licensee requested approval by September 24, 2018.

Compliance with the TS SR 4.3.3.6 could increase the probability of a TS required plant shutdown before the start of refueling outage RF24. If TS SR 4.3.3.6 is performed and any thermocouple strings were found out of tolerance and needed adjustment, they would be required to be removed from the Power Distribution Monitoring System (PDMS). If more than TS allowable thermocouples are removed, the requirements of TS 3.3.3.11.b.2 would no longer be satisfied and PDMS would become inoperable. With an inoperable PDMS, plant maneuvers during the performance of planned pre-outage surveillances and testing would be performed without power distribution monitoring capability and increase the probability of a TS required plant shutdown.

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 50.91(a)(6) of title 10 of the                     *Code of Federal Regulations*                     (10 CFR) 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. 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 no significant hazards consideration, which is presented below:                

1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?

*Response:*                         No.                    

                        The proposed change is a short duration, one-time extension to the surveillance frequency requirement of channel                               ( print page 45690)                            calibrations of the Core Exit Temperature Instrumentation. The performance of the surveillance, or the failure to perform the surveillance, is not a precursor to an accident. An extension in performing the surveillance does not result in the system being unable to perform its function. The systems required to mitigate accidents will remain capable of performing their required functions. No new failure modes have been introduced because of this action and the consequences remain consistent with previously evaluated accidents.                    

Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.

2. Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?

*Response:*                         No.                    

The proposed change only affects the surveillance frequency requirement for the channel calibrations of the Core Exit Temperature Instrumentation. This proposed change does not involve a change to any physical features of the plant, or the manner in which these functions are utilized. No few failure mechanisms will be introduced by the one-time surveillance extension being requested.

Therefore, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.

3. Does the proposed amendment involve a significant reduction in a margin of safety?

*Response:*                         No.                    

The proposed change does not alter any plant setpoints or functions that are assumed to actuate in the event of postulated accidents. The proposed change does not alter any plant feature and only alters the frequency which the surveillance tests must be performed.

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, 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 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 prevention of either resumption of operation or of increase in power output up to the plant's licensed power level, 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 no significant hazards consideration. 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.                

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

                    Within 60 days after the date of publication of this notice, any persons (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. The NRC's regulations are accessible electronically from the NRC Library on the NRC's website at                     *http://www.nrc.gov/​reading-rm/​doc-collections/​cfr/​.*                     Alternatively, a copy of the regulations is available at the NRC's Public Document Room, located at One White Flint North, Room O1-F21, 11555 Rockville Pike (first floor), Rockville, Maryland 20852. 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.                

As required by 10 CFR 2.309(d) the petition should specifically explain the reasons why intervention should be permitted with particular reference to the following general requirements for standing: (1) The name, address, and telephone number of the petitioner; (2) the nature of the petitioner's right under the Act to be made a party to the proceeding; (3) the nature and extent of the 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 petitioner's interest.

In accordance with 10 CFR 2.309(f), the petition must also set forth the specific contentions which the petitioner seeks to have litigated in the proceeding. Each contention must consist of a specific statement of the issue of law or fact to be raised or controverted. In addition, the petitioner must provide a brief explanation of the bases for the contention and a concise statement of the alleged facts or expert opinion which support the contention and on which the petitioner intends to rely in proving the contention at the hearing. The petitioner must also provide references to the specific sources and documents on which the petitioner intends to rely to support its position on the issue. The petition must include sufficient information to show that a genuine dispute exists with the applicant or licensee on a material issue of law or fact. Contentions must be limited to matters within the scope of the proceeding. The contention must be one which, if proven, would entitle the petitioner to relief. A petitioner who fails to satisfy the requirements at 10 CFR 2.309(f) with respect to 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. Parties have the opportunity to participate fully in the conduct of the hearing with respect to resolution of that party's admitted contentions, including the opportunity to present evidence, consistent with the NRC's regulations, policies, and procedures.

Petitions must be filed no later than 60 days from the date of publication of this notice. 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). The petition must be filed in accordance with the filing instructions in the “Electronic Submissions (E-Filing)” section of this document.

                    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. The final determination will serve to establish 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 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                           ( print page 45691)                        an appropriate order or rule under 10 CFR part 2.                

A State, local governmental body, Federally-recognized Indian Tribe, or agency thereof, may submit a petition to the Commission to participate as a party under 10 CFR 2.309(h)(1). The petition should state the nature and extent of the petitioner's interest in the proceeding. The petition should be submitted to the Commission no later than 60 days from the date of publication of this notice. The petition must be filed in accordance with the filing instructions in the “Electronic Submissions (E-Filing)” section of this document, and should meet the requirements for petitions set forth in this section. Alternatively, a State, local governmental body, Federally-recognized Indian Tribe, or agency thereof may participate as a non-party under 10 CFR 2.315(c).

If a hearing is granted, any person who is not a party to the proceeding and is not affiliated with or represented by a party may, at the discretion of the presiding officer, be permitted to make a limited appearance pursuant to the provisions of 10 CFR 2.315(a). A person making a limited appearance may make an oral or written statement of his or her position on the issues but may not otherwise participate in the proceeding. A limited appearance may be made at any session of the hearing or at any prehearing conference, subject to the limits and conditions as may be imposed by the presiding officer. Details regarding the opportunity to make a limited appearance will be provided by the presiding officer if such sessions are scheduled.

## III. Electronic Submissions (E-Filing)

                    All documents filed in NRC adjudicatory proceedings, including a request for hearing and petition for leave to intervene (petition), 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 that request to participate under 10 CFR 2.315(c), must be filed in accordance with the NRC's E-Filing rule (72 FR 49139; August 28, 2007, as amended at 77 FR 46562; August 3, 2012). 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. Detailed guidance on making electronic submissions may be found in the Guidance for Electronic Submissions to the NRC and on the NRC website at                     *http://www.nrc.gov/​site-help/​e-submittals.html.*                     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 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 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 website at                     *http://www.nrc.gov/​site-help/​e-submittals/​getting-started.html.*                     Once a participant has obtained a digital ID certificate and a docket has been created, the participant can then submit adjudicatory documents. Submissions must be in Portable Document Format (PDF). Additional guidance on PDF submissions is available on the NRC's public website at                     *http://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. 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 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 so that they can 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                     *http://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., 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 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 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, 11555 Rockville Pike, Rockville, Maryland 20852, Attention: Rulemaking and Adjudications Staff. Participants filing adjudicatory documents 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://adams.nrc.gov/​ehd,*                     unless excluded pursuant to an order of the Commission or the presiding officer. If you do not have an NRC-issued digital ID certificate as described above, 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                           ( print page 45692)                        information. For example, in some instances, individuals provide home addresses in order to demonstrate proximity to a facility or site. 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.                

For further details with respect to this action, see the application for license amendment dated August 24, 2018, as supplemented August 31, 2018 (ADAMS Accession Nos. ML18236A383 and ML18243A392, respectively).
