NUCLEAR REGULATORY COMMISSION
[Docket No.: 50-483]
Callaway Plant, Unit 1; 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-30 issued to the Union Electric Company (the licensee) for
operation of the Callaway Plant, Unit 1, in Callaway County, Missouri.
The proposed amendment, submitted in the licensee's application
dated September 9, 2005, would revise Surveillance Requirements (SRs)
3.7.3.1 and 3.7.3.2 and add SR 3.7.3.3 in Technical Specification (TS)
3.7.3, ``Main Feedwater Isolation Valves (MFIVs).'' The new SR 3.7.3.3
would add Figure 3.7.3-1, the acceptable valve closure time versus the
steam generator pressure for the MFIVs, to the TSs.
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.
The Commission has made a proposed determination that the amendment
request involves no significant hazards consideration. Under the
Commission's regulations in Title 10 of the Code of Federal Regulations
(10 CFR), Section 50.92, this means that operation of the facility in
accordance
[[Page 54777]]
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. Revision of the MFIV stroke time limit has no
impact on the frequency of occurrence of those events for which
feedwater isolation is credited or assumed. The MFIVs themselves are
not part of the initiating mechanisms or failure modes for such
events (such as steamline break or feedwater line break). Therefore,
the proposed change has no impact on the probability of occurrence
of such events and does not involve a significant increase in the
probability of an accident previously evaluated.
With regard to consequences of previously evaluated accidents,
evaluations were documented in References 7.1, 7.2, and 7.3 [(the
licensee's letters to the Nuclear Regulatory Commission dated June
27 and December 12, 2003, and September 17, 2004, respectively)]
that assessed the impact of the change in MFIV actuators and an
associated 15-second MFIV stroke time (for operating conditions that
include secondary system pressures above the reference pressure that
corresponds to [the] P-11 permissive) on LOCA [loss-of-coolant
accident] mass and energy releases; main steamline break mass and
energy releases; LOCA and LOCA related transients; non-LOCA
transients; LOCA hydraulic forces and steam releases used for
radiological consequence calculations. The consequences of those
evaluations are not adversely affected by the proposed change to an
increasing MFIV stroke time limit where appropriate for lower
secondary system pressures. The evaluations discussed in Section 4.0
[of Attachment 2 to the licensee's application dated September 9,
2005,] demonstrate that such an increase in the MFIV stroke time
from the 15 seconds assumed in the analyses performed in support of
the Callaway RSG [Replacement Steam Generator] Program (Reference
7.3) to a higher bounding stroke time value of 90 seconds where
appropriate for lower secondary system pressures is acceptable with
respect to the impacted accident analyses. The resulting
interpolated TS curve proposed as TS Figure 3.7.3-1 provides an MFIV
stroke time limit that is pressure dependent but bounding, as it
ensures the applicable FSAR [Callaway Final Safety Analysis Report]
Chapter 15 events that credit MFIV closure remain bounding.
Therefore, the proposed change does not result in 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 any hardware
or design changes [n]or any changes in the methods by which safety-
related plant systems perform their safety function. No new accident
scenarios, transient precursors, failure mechanisms, or limiting
single failures are introduced as a result of this request. There
will be no adverse effect or challenges imposed on any safety-
related system as a result of the proposed change.
Therefore, the proposed change does not create 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 changes to incorporate a pressure-
dependent MFIV surveillance stroke time limit and to delete the
Notes on SR 3.7.3.1 and SR 3.7.3.2 do not affect any safety analysis
acceptance criteria nor involve any change to a safety analysis
limit, limiting safety system setting, or safety system performance
criterion. There will be no effect on the manner in which safety
limits or limiting safety system settings are determined nor will
there be any effect on those plant systems necessary to assure the
accomplishment of protection functions. The radiological dose
consequence acceptance criteria will continue to be met. There will
be no significant impact on the overpower limit, departure from
nucleate boiling ratio limits, heat flux hot channel factor (FQ),
nuclear enthalpy rise hot channel factor (F-delta-H), loss[-]of[-
]coolant accident peak cladding temperature (LOCA PCT), peak local
power density, or any other margin of safety. The radiological dose
consequence acceptance criteria listed in the Standard Review Plan
will continue to be met.
Therefore, the proposed change does not involve a significant
reduction in the 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 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 period provided that its final determination is that 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.
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
(PDR), located at One White Flint North, Public File Area O1 F21, 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 O1
F21, 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/. If a request for a hearing or petition for
[[Page 54778]]
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 requestors/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 is aware and on which the
petitioner intends to rely to establish those facts or expert opinion.
The petition must include 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 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 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(c)(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,
Washington, DC 20555-0001, Attention: Rulemaking and Adjudications
