II. Introduction

    The NRC is considering issuance of an amendment to Facility 
Operating License No. NPF-90, issued to the Tennessee Valley Authority, 
for operation of WBN, Unit 1, located in Rhea County, Tennessee.
    The proposed amendment modifies the technical specifications to 
define support systems needed in the first 48 hours after a unit 
shutdown when steam generators are not available for heat removal. The 
proposed change is required to support dual unit operation of WBN (a 
licensing decision for WBN Unit 2 is currently expected to be made in 
the fall of 2015). The proposed amendment also requests changes 
consistent with TSTF-273-A, Revision 2, to provide clarifications 
related to the requirements of the SFDP.
    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 likelihood of a malfunction of any systems, structures or 
components (SSCs) supported by containment cooling system (CCS) and 
essential raw cooling water (ERCW) is not significantly increased by 
adding new technical specification (TS) for ERCW and CCS that 
require alternate CCS and ERCW system alignments during the first 48 
hours after shut down of a unit when the steam generators are not 
available for heat removal. CCS and ERCW provide the means for 
transferring residual and decay heat to the Residual Heat Removal 
(RHR) System for process and operating heat from safety related 
components during a transient or accident, as well as during normal 
operation. Although the proposed change includes a design change to 
allow two ERCW pumps to be powered from one diesel generator (DG), 
the additional ERCW pump is only aligned to the DG on a non-accident 
unit during a design basis event on the other unit, and does not 
result in overloading the DG due to the reduced loading on the non-
accident DG. The CCS and ERCW are not initiators of any analyzed 
accident. All equipment supported by CCS and ERCW has been evaluated 
to demonstrate that their performance and operation remains as 
described in the FSAR with no increase in probability of failure or 
malfunction.
    The SSCs credited to mitigate the consequences of postulated 
design basis accidents remain capable of performing their design 
basis function. The change in CCS and ERCW system alignments has 
been evaluated to ensure the RHR System remains capable of removing 
normal operating and post-accident heat. Additionally, all the CCS 
and ERCW supported equipment, credited in the accident analysis to 
mitigate an accident, has

[[Page 42556]]

been shown to continue to perform their design function as described 
in the FSAR.
    Therefore, the proposed change does not involve a significant 
increase in the probability or consequences of an accident 
previously evaluated.
    The proposed TS changes add explanatory text to the programmatic 
description of the Safety Function Determination Program (SFDP) in 
TS 5.7.2.18 to clarify the requirements that consideration does not 
have to be made for a loss of power in determining loss of function. 
The Bases for LCO 3.0.6 is revised to provide clarification of the 
``appropriate LCO for loss of function,'' and that consideration 
does not have to be made for a loss of power in determining loss of 
function. The changes are editorial and administrative in nature, 
and therefore do not increase the probability of any accident 
previously evaluated. No physical or operational changes are made to 
the plant. The proposed changes do not 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 create the possibility of a new or 
different kind of accident from any accident previously evaluated. 
The proposed change does not introduce any new modes of plant 
operation, change the design function of any SSC, or change the mode 
of operation of any SSC. There are no new equipment failure modes or 
malfunctions created as the affected SSCs continue to operate in the 
same manner as previously evaluated and have been evaluated to 
perform their safety functions when in the alternate alignments as 
assumed in the accident analysis. Additionally, accident initiators 
remain as described in the FSAR and no new accident initiators are 
postulated as a result of the alternate CCS and ERCW alignments.
    Therefore, the proposed change does not create the possibility 
of a new or different kind of accident from any accident previously 
evaluated.
    The proposed changes [to TS 5.7.2.18] are editorial and 
administrative in nature and do not result in a change in the manner 
in which the plant operates. The loss of function of any specific 
component will continue to be addressed in its specific TS LCO, and 
plant configuration will be governed by the required actions of 
those LCOs. The proposed changes are clarifications that do not 
degrade the availability or capability of safety related equipment, 
and therefore do not create the possibility of a new or different 
kind of accident from any accident previously evaluated. There are 
no design changes associated with the proposed changes, and the 
changes do not involve a physical alteration of the plant (i.e., no 
new or different type of equipment will be installed). The changes 
do not alter assumptions made in the safety analysis, and are 
consistent with the safety analysis assumptions and current plant 
operating practice. Due to the administrative nature of the changes, 
they cannot be an accident initiator.
    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 change involve a significant reduction in a 
margin of safety?
    Response: No.
    The proposed change continues to ensure that the cooling 
capability of RHR during normal operation and during the mitigation 
of a design basis event remains within the evaluated equipment 
limits and capabilities assumed in the accident analysis. The 
proposed change does not result in any changes to plant equipment 
functions, including setpoints and actuations. The proposed change 
does not alter existing limiting conditions for operation, limiting 
safety system settings, or safety limits specified in the Technical 
Specifications. The proposed change to add a new TS for ERCW and CCS 
assures the ability of these systems to support post-accident 
residual heat removal.
    Therefore, since there is no adverse impact of this change on 
the Watts Bar Nuclear Plant safety analysis, there is no significant 
reduction in the margin of safety of the plant.
    The proposed changes to TS 5.7.2.18 are clarifications and are 
editorial and administrative in nature. No changes are made to the 
LCOs for plant equipment, the time required for the TS Required 
Actions to be completed, or the out of service time for the 
components involved. The proposed changes do not affect the safety 
analysis acceptance criteria for any analyzed event, nor is there a 
change to any safety analysis limit. The proposed changes do not 
alter the manner in which safety limits, limiting safety system 
settings or limiting conditions for operation are determined, nor is 
there any adverse effect on those plant systems necessary to assure 
the accomplishment of protection functions. The proposed changes 
will not result in plant operation in a configuration outside the 
design basis.
    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 
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.

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 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 http://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

[[Page 42557]]

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 [email protected], 
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 http://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 http://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 http://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 http://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

[[Page 42558]]

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 http://www.nrc.gov/site-help/e-submittals.html, by email to 
[email protected], 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 
http://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.
