NUCLEAR REGULATORY COMMISSION
[Docket No. 50-390]
Tennessee Valley Authority; Notice of Consideration of Issuance
of Amendment to Facility Operating License, Proposed No Significant
Hazards Consideration Determination, and Opportunity for a Hearing
The U.S. Nuclear Regulatory Commission (the Commission) is
considering issuance of an amendment to Facility Operating License No.
NPF-90, issued to Tennessee Valley Authority (the licensee), Docket No.
50-390, Watts Bar Nuclear Plant, Unit 1, Rhea County, Tennessee.
The proposed amendment would provide a one-time change to Function
4a, ``Reactor Coolant System (RCS) Hot Leg Temperature Indication,'' of
Technical Specification (TS) Table 3.3.4-1. The proposed amendment
would allow Watts Bar Unit 1 to continue operating until the next
refueling outage (scheduled for the spring of 2005) with one out of
four RCS hot leg temperature indications inoperable in the Auxiliary
Control Room.
The reason for the exigency is the unanticipated failure of
Temperature Indicator (TI) 1-TI-68-65C that provides indication in the
Auxiliary Control Room (ACR) for the hot leg temperature of RCS Loop 4.
Upon discovery of this condition, TVA entered Action A of TS 3.3.4. The
30-day allowed outage time for Action A of TS 3.3.4 will expire on
November 20, 2004, at approximately 2:27 p.m. e.s.t. Based on the
actions taken, the problem most likely exists in the instrumentation
(transmitter or thermocouple) located within the Reactor Building's
Polar Crane Wall. While the plant is operating, the radiological
conditions in this area prohibit access by plant personnel. Therefore,
the repairs cannot be safely implemented until the unit is shut down.
If the proposed amendment is not granted, TS 3.3.4 would require that
plant to be shut down by November 20, 2004, as repairs to the Loop 4 TI
cannot be made while operating. The shutdown of the plant would result
in an unnecessary operational transient since the indication parameters
that remain available in the ACR are adequate to safely shut down the
plant should an emergency arise.
Before issuance of the proposed license amendment, the Commission
will have made findings required by the Atomic Energy Act of 1954, as
amended (the Act) and the Commission's regulations.
Pursuant to 10 CFR 50.91(a)(6) for amendments to be granted under
exigent circumstances, the NRC staff must determine that the amendment
request involves no significant hazards consideration. Under the
Commission'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 change involve a significant increase in
the probability or consequences of an accident previously evaluated?
No. The proposed TS change to allow operation with only 3 of 4
loop remote shutdown indications for Reactor Coolant System hot leg
temperature until the Spring 2005 refueling outage is only
applicable to the following conditions:
1. Fire or smoke in the Main Control Room (MCR),
2 An evacuation of the MCR due to some other (non-fire) unspecified
reason, and
3. The design basis flood.
The inoperability of the one T(hot) indicator does not change
the probability of occurrence for these events since it is not an
accident initiator. The T(hot) indicators on the four loops are non-
safety related equipment. During safe shutdown for a MCR evacuation
event, design basis flood or fire related event, no fuel damage is
postulated to occur, nor is the integrity of the reactor coolant
pressure boundary or containment barriers postulated to be lost.
Sufficient redundancy exists with the operational instrumentation to
ensure that decay heat removal functions are not adversely impacted
by this change. 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?
No. The proposed TS change does not alter the function of the
Remote Shutdown System which is to achieve and maintain safe reactor
shutdown from outside the MCR. The TS instrumentation and controls
required will be such that sufficient capability is retained for
[[Page 64597]]
decay heat removal via the Steam Generators (SGs) to provide the
indication required for safe shutdown capabilities. The change will
not result in the installation of any new equipment or system. The
T(hot) instrument is used for indication only and has no automatic
control functions. No new operations procedures will be created by
this change. Appropriate operational procedures will be updated to
clarify that the Loop 4 T(hot) indication in the Auxiliary Control
Room (ACR) is not available during the remainder of Cycle 6. No new
operating conditions or modes will be created by this proposed
change. 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
margin of safety?
No. The radiological dose consequences are not impacted since
this change is only applicable to the following conditions:
1. Fire or smoke in the Main Control Room (MCR),
2 An evacuation of the MCR due to some other (non-fire) unspecified
reason, and
3. The design basis flood.
During safe shutdown for a MCR evacuation event, design basis
flood or fire related event, no fuel damage is postulated to occur,
nor is the integrity of the reactor coolant pressure boundary or
containment barriers postulated to be lost. Sufficient redundancy
exists with the operational instrumentation to ensure that decay
heat removal functions are not adversely impacted by this change.
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
amendment request involves no significant hazards consideration.
The Commission is seeking public comments on this proposed
determination. 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, should 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 no significant hazards consideration. The final
determination will consider all public and State comments received.
Should the Commission take 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.
Written comments may be submitted by mail to the Chief, Rules and
Directives Branch, Division of Administrative Services, Office of
Administration, U.S. Nuclear Regulatory Commission, Washington, DC
20555-0001, and should cite the publication date and page number of
this Federal Register notice. Written comments may also be delivered to
Room 6D59, Two White Flint North, 11545 Rockville Pike, Rockville,
Maryland, from 7:30 a.m. to 4:15 p.m. Federal workdays. Documents may
be examined, and/or copied for a fee, at the NRC's Public Document
Room, located at One White Flint North, 11555 Rockville Pike (first
floor), Rockville, Maryland.
The filing of requests for hearing and petitions for leave to
intervene is discussed below.
Within 60 days after the date of publication of this notice, the
licensee may file a request for a hearing with respect to issuance of
the amendment to the subject facility operating license and any person
whose interest may be affected by this proceeding and who wishes to
participate as a party in the proceeding must file a written request
for a hearing and a petition for leave to intervene. Requests for a
hearing and a petition for leave to intervene shall be filed in
accordance with the Commission's ``Rules of Practice for Domestic
Licensing Proceedings'' in 10 CFR part 2. Interested persons should
consult a current copy of 10 CFR 2.309, which is available at the
Commission's PDR, located at One White Flint North, Public File Area
01F21, 11555 Rockville Pike (first floor), Rockville, Maryland.
Publicly available records will be accessible from the Agencywide
Documents Access and Management System's (ADAMS) Public Electronic
Reading Room on the Internet at the NRC Web site, http://www.nrc.gov/reading-rm/doc-collections/cfr/. (Note: Public access to ADAMS has been
temporarily suspended so that security reviews of publicly available
documents may be performed and potentially sensitive information
removed. Please check the NRC Web site for updates on the resumption of
ADAMS access.) If a request for a hearing or petition for leave to
intervene is filed by the above date, the Commission or a presiding
officer designated by the Commission or by the Chief Administrative
Judge of the Atomic Safety and Licensing Board Panel, will rule on the
request and/or petition; and the Secretary or the Chief Administrative
Judge of the Atomic Safety and Licensing Board will issue a notice of a
hearing or an appropriate order.
As required by 10 CFR 2.309, a petition for leave to intervene
shall 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 petition should 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 petition must
also identify the specific contentions which the petitioner/requestor
seeks to have litigated at 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/requestor shall 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/requestor must also provide references to those specific
sources and documents of which the petitioner/requestor is aware and on
which the petitioner/requestor intends to rely to establish those facts
or expert opinion. The petitioner/requestor must provide sufficient
information to show that a genuine dispute exists with the applicant on
a material issue of law or fact. Contentions shall be limited to
matters within the scope of the amendment under consideration. The
contention must be one which, if proven, would entitle the petitioner/
requestor to relief. A petitioner/requestor who fails to satisfy these
requirements 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,
and have the opportunity to participate fully in the conduct of the
hearing.
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
[[Page 64598]]
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, any hearing held would take place before the issuance of
any amendment.
Nontimely requests and/or petitions and contentions will not be
entertained absent a determination by the Commission or the presiding
officer of the Atomic Safety and Licensing Board that the petition,
request and/or the contentions should be granted based on a balancing
of the factors specified in 10 CFR 2.309(a)(1)(i)-(viii).
A request for a hearing or a petition for leave to intervene must
be filed by: (1) First class mail addressed to the Office of the
Secretary of the Commission, U.S. Nuclear Regulatory Commission,
