II. Introduction

    The NRC is considering issuance of an amendment to Renewed Facility 
Operating License No. DPR-50, issued to TMI, for operation of Unit 1, 
located in Dauphin County, Pennsylvania.
    This amendment proposes changes to the technical specifications to 
allow for the temporary connection of the BWST to non-seismic piping 
for cleanup and recirculation to support activities associated with the 
TMI-1 Fall 2015 Refueling Outage and Fuel Cycle 21 operation.
    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 (LAR) 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 amendment involve a significant increase in 
the probability or consequences of an accident previously evaluated?
    Response: No.
    The use of the Liquid Waste Disposal System (WDL) and the Spent 
Fuel Pool Cooling System (SF) to re-circulate and cleanup the BWST 
contents does not involve any physical changes or modifications to 
the plant, or create any new interfaces with the reactor coolant 
system. Therefore, the connection of the WDL and SF to the BWST 
would not affect the probability of Large and Small Break Loss of 
Coolant Accidents occurring. The WDL and the applicable components 
of the SF are not credited for safe shutdown of the plant or 
accident mitigation. A technical evaluation was performed to 
validate the seismic adequacy of the WDL piping to withstand a Safe 
Shutdown Earthquake (SSE). The evaluation determined sufficient 
margin exists in the installed piping and supports such that during 
an SSE, the WDL system and piping would not lose pressure boundary 
integrity. In addition, as additional defense-in-depth measure, 
administrative controls ensure that the BWST can be isolated from 
seismic Class II WDL piping following an SSE. Since the BWST will 
continue to perform its safety functions and overall system 
performance is not affected, the consequences of an accident are not 
increased.
    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 design of the BWST, WDL and SF systems to allow 
recirculation and filtration/demineralization has not been altered. 
No new procedures are required to start or end BWST Cleanup or 
Recirculation operation. Proposed changes to the existing operating 
procedures will provide a higher priority and quicker response to 
isolate the BWST from seismic Class II piping paths, if operating in 
Cleanup or Recirculation modes, as an additional defense-in-depth 
administrative control during a seismic event. Since the seismic 
adequacy of the interconnected WDL system and piping has been 
evaluated for an SSE and validated by calculations to maintain 
pressure boundary integrity, the BWST safety functions are not 
affected.
    Therefore, the proposed changes do 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 WDL and applicable components of the SF are not credited for 
safe shutdown of the plant or accident mitigation. The seismic 
adequacy of the BWST is maintained. The seismic evaluation 
determined that sufficient margin exists in the installed piping and 
supports such that during an SSE, the seismic Class II WDL system 
and piping would not lose pressure boundary integrity. Maximum 
piping and piping support stresses are below their respective 
allowables, are acceptable, and no pipe leakage will occur.
    Therefore, the proposed changes do 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 LAR 
involves no significant hazards consideration.
    The NRC is seeking public comments on this proposed determination 
that the LAR 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-

[[Page 47531]]

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.

III. 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 LAR. 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/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.

IV. 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

[[Page 47532]]

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, 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.
    For further details with respect to this action, see the 
application for license amendment dated July 23, 2015 (ADAMS Accession 
No. ML15204A843), as supplemented by letter dated July 28, 2015 (ADAMS
