WAIS Document Retrieval
[Federal Register: November 9, 1994]
NUCLEAR REGULATORY COMMISSION
Biweekly Notice; Applications and Amendments to Facility
Operating Licenses Involving No Significant Hazards Considerations I. Background Pursuant to Public Law 97-415, the U.S. Nuclear Regulatory Commission (the Commission or NRC staff) is publishing this regular
biweekly notice. Public Law 97-415 revised section 189 of the Atomic
Energy Act of 1954, as amended (the Act), to require the Commission to
publish notice of any amendments issued, or proposed to be issued, under a new provision of section 189 of the Act. This provision grants
the Commission the authority to issue and make immediately effective
any amendment to an operating license upon a determination by the
Commission that such amendment involves no significant hazards
consideration, notwithstanding the pendency before the Commission of a
request for a hearing from any person.
This biweekly notice includes all notices of amendments issued, or
proposed to be issued from October 17, 1994, through October 28, 1994.
The last biweekly notice was published on October 26, 1994 (59 FR
53834).Notice of Consideration of Issuance of Amendments to Facility Operating
Licenses, Proposed No Significant Hazards Consideration Determination, and Opportunity for a Hearing The Commission has made a proposed determination that the following
amendment requests involve 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) file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (1 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval 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. The
basis for this proposed determination for each amendment request is shown
below. 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 the 30-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 30-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
before action is taken. Should the Commission take this action, it
will publish in the Federal Register a notice of issuance and provide for
opportunity for a hearing 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 Rules Review and
Directives Branch, Division of Freedom of Information and Publications
Services, Office of Administration, U.S. Nuclear Regulatory
Commission, Washington, DC 20555, and should cite the publication date and page
number of this Federal Register notice. Written comments may also be
delivered to Room 6D22, Two White Flint North, 11545 Rockville Pike, Rockville, Maryland from 7:30 a.m. to 4:15 p.m. Federal workdays.
Copies of written comments received may be examined at the NRC Public
Document Room, the Gelman Building, 2120 L Street, NW., Washington, DC
20555. The filing of requests for a hearing and petitions for leave to
intervene is discussed below.
By December 9, 1994, 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 file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (2 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval 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 2.714 which is available at the Commission's Public Document Room, the Gelman
Building, 2120 L Street, NW., Washington, DC 20555 and at the local
public document room for the particular facility involved. If a
request for a hearing or petition for leave to intervene is filed by the above
date, the Commission or an Atomic Safety and Licensing Board, designated by the Commission or by the Chairman of the Atomic Safety and Licensing Board Panel, will rule on the request and/or petition;
and the Secretary or the designated Atomic Safety and Licensing Board
will issue a notice of a hearing or an appropriate order.
As required by 10 CFR 2.714, 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 factors: (1) the nature of the petitioner's right under the
Act to be made a party to the proceeding; (2) the nature and extent of
the petitioner's property, financial, or other interest in the proceeding; and (3) the possible effect of any order which may be
entered in the proceeding on the petitioner's interest. The petition
should also identify the specific aspect(s) of the subject matter of
the proceeding as to which petitioner wishes to intervene. Any person
who has filed a petition for leave to intervene or who has been
admitted as a party may amend the petition without requesting leave of
the Board up to 15 days prior to the first prehearing conference
scheduled in the proceeding, but such an amended petition must satisfy
the specificity requirements described above.
Not later than 15 days prior to the first prehearing conference
scheduled in the proceeding, a petitioner shall file a supplement to
the petition to intervene which must include a list of the contentions
which are sought to be litigated in the matter. Each contention must
consist of a specific statement of the issue of law or fact to be
raised or controverted. In addition, the petitioner shall provide a
brief explanation of the bases of the contention and a concise file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (3 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval 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 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. Petitioner 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 to relief. A
petitioner who fails to file such a supplement which satisfies 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, including the opportunity to present evidence and cross-
examine witnesses.
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.
A request for a hearing or a petition for leave to intervene must
be filed with the Secretary of the Commission, U.S. Nuclear Regulatory
Commission, Washington, DC 20555, Attention: Docketing and Services
Branch, or may be delivered to the Commission's Public Document Room, the Gelman Building, 2120 L Street, NW., Washington DC 20555, by the
above date. Where petitions are filed during the last 10 days of the
notice period, it is requested that the petitioner promptly so inform
the Commission by a toll-free telephone call to Western Union at 1-800-
248-5100 (in Missouri 1-800-342-6700). The Western Union operator
should be given Datagram Identification Number N1023 and the following file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (4 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval message addressed to (Project Director): petitioner's name and telephone number, date petition was mailed, plant name, and
publication date and page number of this Federal Register notice. A copy of the petition should also be sent to the Office of the General Counsel, U.
S.
Nuclear Regulatory Commission, Washington, DC 20555, and to the
attorney for the licensee.
Nontimely filings of petitions for leave to intervene, amended
petitions, supplemental petitions and/or requests for a hearing will
not be entertained absent a determination by the Commission, the
presiding officer or the Atomic Safety and Licensing Board that the
petition and/or request should be granted based upon a balancing of
factors specified in 10 CFR 2.714(a)(1) (i)-(v) and 2.714(d).

Carolina Power & Light Company, et al.
Docket Nos. 50-325 and 50-324
Brunswick Steam Electric Plant, Units 1 and 2, Brunswick County, North Carolina.
Date of amendments request: September 30, 1994.
Description of amendments request: The amendments would revise the
Technical Specifications to eliminate the scram and isolation trip
functions from the main steam line radiation monitor (MSLRM). This
change would specifically remove the reactor scram, main steam line
isolation valve closure, main steam line drain valve closure, reactor
water sample line isolation, and mechanical vacuum pump line isolation
actuated on a MSLRM High-High Radiation signal. The actuation signal
for isolation of the reactor water sample line will be replaced with a
low condenser vacuum signal. The isolation of the mechanical vacuum
pump line will be changed to a signal from the main stack radiation
monitor.
The MSLRMs will have both High Radiation and High-High Radiation
alarms. The setpoint for the MSLRM High Radiation alarm will be set at
or below 1.5 times the nominal full power background radiation
adjusted for Hydrogen water chemistry operation. The setpoint for the condenser file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (5 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval off-gas radiation monitor will be set at a value of 1.5 times background radiation, but not less than 1.5 Rem per hour.
Basis for proposed no significant hazards consideration determination: 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. The proposed amendments do not involve a significant increase
in the probability or consequences of an accident previously evaluated.
The deletion of the MSLRM trip function from the reactor scram and the
Group 1 isolation initiation logic removes a potential transient
initiation and therefore decreases the probability of plant transients
occurring due to inadvertent scrams resulting from this system.
The deletion of the MSLRM trip function from the Main Steam Drain Valve, the Reactor Water Sample Isolation Valve, and the Mechanical Vacuum Pump line isolation logic, does not affect the initiators of
any accident previously evaluated in the Safety Analysis Report.
Therefore, the proposed change does not involve an increase in the probability of
occurrence of any accident previously evaluated.
The NRC staff acceptance criterion for the Control Rod Drop
Accident is that the doses from the accident fall significantly below
the limits given in 10 CFR Part 100. The releases calculated for
accident during plant operations when the Steam Jet Air Ejectors (SJAE) are operating and when the Mechanical Vacuum Pumps are operating are within these acceptance limits.
In NEDO-31400, GE shows that the occurrence of a CRDA, with the
MSL high radiation isolation removed, and SJAE in operation, results in
offsite radiological exposures that are small fractions of 10CFR100
guidelines. Since the Brunswick specific CRDA doses are lower than the
[sic] calculated by GE and the GE dose parameters envelope those used
for the Brunswick analysis, it is concluded that the NRC's findings
that the radiological release consequence is within the staff's
acceptance criteria, even without the automatic MSIV trip, is
applicable to Brunswick.
While not specifically addressed in the GE evaluation, Carolina
Power and Light also proposes to eliminate the Main Steam Line Drain
valves, the Reactor Water Sample Line isolation valves, and the
mechanical vacuum line isolation valves from the MSLRM isolation
logic. file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (6 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval Main Steam Line Drain Valves B21-F016 and B21-F019 drain to the main condenser, which is the same flow path as the MSIVs. The discharge of
both the MSIV and MSL drain flow paths is processed through the offgas system. Any radiation released through the drain valves during a control rod drop accident will be negligible and, for Brunswick, is
bounded by the NEDO analysis.
The reactor water sample line provides a small amount of reactor
water to the Reactor Building Sample Panel. The discharge of the Reactor Building Sample Panel is routed through the floor drain sump
to the liquid radwaste system. Any releases through this path would be
negligible and, for Brunswick, is bounded by the NEDO analysis.
The mechanical vacuum pumps are used only when the reactor is at
low power (less than 5%) and there is insufficient steam flow to operate the Steam Jet Air Ejectors. The increase in radiation will be detected by the MSLRMs and annunciated in the Main Control Room.
Operators will be instructed, in the annunciator response procedures, to take action to stop the Mechanical Vacuum Pump(s) and isolate the
Mechanical Vacuum Pump line. The amount of radiation released prior to
isolating the line would represent the most limiting case for this
accident. However, it will still be well within 10 CFR Part 100
limits.
Additionally, the dose received in the Main Control Room as a result
of this accident is within General Design Criteria 19 (SRP 6.4) limits.
Therefore, since elimination of the MSIV [sic, MSLRM] scram and
isolation functions would not result in an increase in exposure above NRC acceptance limits, the proposed changes will not significantly
increase the consequences of a previously evaluated accident.
- 2. The proposed amendments would not create the possibility of a
new or different kind of accident from any accident previously
evaluated. The function of a MSLRM trip is to detect abnormal fission
product release and isolate the steam lines, thereby stopping the
transport of fission products from the reactor to the main condenser.
The monitors do not perform a prevention function for any kind of
accident. The existence of a MSLRM trip does not prevent the
occurrence
of a fuel failure event or any other type of event. The elimination of
these signals, which served only in a mitigative function, does not
create the possibility of a new or different kind of accident from
those previously evaluated. Also, radiation monitors with alarm
functions will remain installed in the plant to warn the operators of
a file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (7 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval high radiation condition in the main steam lines, or in the off-gas system. Thus no new or different accident can be postulated by the
proposed changes.
- 3. The proposed amendments do not involve a significant reduction in a margin of safety. As shown in the topical report, the changes
represent an overall improvement in plant safety. Safe operation of
the plant is further enhanced by elimination of the unnecessary scram and isolation of the reactor vessel. With implementation of these changes,
- 1) the primary heat sink (main condenser) remains available, 2) large
transients on the reactor vessel, as well as challenges to the ESF, are avoided, and 3) the Offgas system remains available to control the
pathway of potential releases. As such, the margin of safety is enhanced by the proposed changes.
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.

Docket No. 50-261 H. B. Robinson Steam Electric Plant, Unit No. 2, Darlington
- County, South Carolina.
Date of amendment request: October 7, 1994.
Description of amendment request: The proposed amendment would
revise the introduction to TS Section 6.9.3.3 to require the approved
revision number for the referenced analytical methods be listed in the
Core Operating Limits Report. The methodology referenced in 6.9.3.3.b.
f (XN-NF-82-49(A)) will be updated to clarify that all supplements are
included. New methodologies ANF-89-151(A) and EMF-92-081(A) will be file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (8 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval added to TS Section 6.9.3.3.b.
Basis for proposed no significant hazards consideration
determination: 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. The proposed amendment does not involve a significant increase
in the probability or consequences of an accident previously
evaluated.
The proposed changes will have no influence on the probability of an
accident previously evaluated.
No changes will be made to any safety
related equipment, systems, or setpoints used in determining the
probability of an evaluated accident. The plant design basis will not
be altered. Therefore, there will be no significant increase in the
probability of an accident previously evaluated.
Consequences are dependent on the type of accident and the mitigating response of safety related equipment. Furthermore, the
magnitude of consequences are calculated, directly or through
supporting calculations, by use of NRC approved methodologies. The
proposed license amendment will not alter the function of safety
related equipment designed to mitigate the consequences of an accident
previously evaluated or allow operation of the facility outside any
current limitations or restrictions. Also, this amendment will not
alter the requirement that evaluation of the consequences of an
accident previously evaluated by determined/supported with NRC
reviewed and approved methodologies. The change to TS Section 6.9.3.3.b's
introductory wording satisfies an administrative commitment and the requirements it adds are administrative in nature. Accordingly the
proposed license amendment will not involve a significant increase in
the probability or consequences of an accident previously evaluated.
- 2. The proposed amendment does not create the possibility of a new
or different kind of accident from any accident previously evaluated.
The addition of and update to NRC previously reviewed and approved
methodologies in TS Section 6.9.3.3.b will not result in any design or
function changes to any safety related equipment designed to prevent
and/or mitigate accidents, to any setpoints or systems, or to any
portion of the plant design basis. Operation of the facility will
remain within all required limitations and/or restrictions. The change
to TS Section 6.9.3.3.b's introductory wording satisfies an
administrative commitment and the requirements it adds are
administrative in nature. Therefore, the proposed amendment will not
create the possibility of a new kind of accident from any accident
previously evaluated.
file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (9 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval The addition of and update to NRC previously reviewed and approved methodologies in TS Section 6.9.3.3.b will not result in any design or
function changes to any safety related equipment designed to prevent and or mitigate accidents, to any setpoints or systems, or to any portion of the plant design basis. Operation of the facility will
remain within all required limitations and/or restrictions. The
changes to TS Section 6.9.3.3.b's introductory wording satisfies an administrative commitment and the requirements it adds are
administrative in nature. Therefore, the proposed amendment will not
create the possibility of a different kind of accident from any
accident previously evaluated.
- 3. The proposed amendment does not involve a significant reduction
in the margin of safety. The proposed license amendment is defined as administrative in nature.
No current operational limits, restrictions, or operating modes of the facility and its equipment, safety related
or otherwise, designed to preserve the margin of safety will be changed
or affected by the proposed amendment. There will be no changes to
setpoints or to the plant design basis. The methodology proposed for
addition to TS Section 6.9.3.3.b and the methodology that will be
updated has been previously reviewed and approved by the NRC. The
change to TS Section 6.9.3.3.b's introductory wording satisfies an
administrative commitment and the requirements it adds are
administrative in nature. Accordingly the proposed license amendment
will 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

file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (10 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval Date of amendment request: October 12, 1994.
Description of amendment request: The proposed amendment requests
the closure and deletion of License Condition 2.C.(26) related to turbine disk integrity.
Basis for proposed no significant hazards consideration
determination: 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. No significant increase in the probability or consequences of
an accident previously evaluated results from this change.
The proposed change would close and delete License Condition
2.C.(26). The approved methodology currently used to evaluate the
probability of rotor failure and the inspection interval will not be changed. The closure and deletion of the license condition is an administrative change and will affect any accident previously
evaluated.
The bounding accident for the turbine-generator as analyzed in the
Grand Gulf Nuclear Station (GGNS) Updated Final Safety Analysis Report (UFSAR) is the occurrence of an external missile resulting from the
failure of a low pressure (LP) turbine disc. The probability of this
incident occurring is less than 1 x 10-5 per year, which is the
NRC acceptable failure criterion for probability.
Any extension to the service interval in the future will be
evaluated in accordance with the current methodology. The original
acceptable levels of failure will be maintained. Therefore, no significant increase in the probability or consequences of a previously
evaluated accident results from this change.
- 2. The change would not create the possibility of a new or
different kind of accident from any previously evaluated.
The proposed change does not involve a change to the control logic
or operating procedures for the turbine but rather transfers the
control of the LP turbine disc inspection interval from the Operating
License to administrative control. The current approved methodology
will continue to be used when determining future inspection intervals.
Therefore, this change does not create the possibility of a new or
different kind of accident from any previously evaluated.
- 3. The change would not involve a significant reduction in a
margin of safety.
Closing and deleting the current license condition for LP turbine
disc inspections and controlling the inspection interval file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (11 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval administratively has no adverse effects to the margin of safety. The current approved methodology for failures will continue to be used and
any changes to future inspection intervals will be evaluated by the methodology. This change does not affect any previous safety analysis presented in the UFSAR and does not affect the criteria used to
establish safety limits, the basis for limiting safety system
- settings, the basis for limiting conditions of operation, a change to the technical specifications or a change in plant operations.
Therefore, this 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.

Docket Nos. 50-250 and 50-251
Turkey Point Plant, Units 3 and 4, Dade County, Florida.
Date of amendment request: October 20, 1994.
Description of amendment request: The licensee proposes to change
Turkey Point, Units 3 and 4 Technical Specifications (TS) by revising
TS 1.9, Definitions--CORE ALTERATIONS to only address activities which
may, in actuality, affect core reactivity. In addition, the licensee
proposes to revise TS 3.9.4, Containment Building Penetrations to
allow both containment personnel airlock (PAL) doors to be open during core
alterations and movement of irradiated fuel in containment provided (a) that at least one PAL door is capable of being closed; (b) the plant
is in Mode 6 with at least 23 feet of water above the fuel; and (c) a
designated individual is available outside the PAL to close the door.
The licensee also proposes a revision to the footnote of TS 3.9.4, to
remove the description of the purpose for imposing administrative file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (12 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval controls. Basis for proposed no significant hazards consideration
determination: 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) Operation of the facility in accordance with the proposed
amendments would not involve a significant increase in the probability
or consequences of an accident previously evaluated.
The change in the definition of CORE ALTERATIONS would allow the
movement of a temporary source range detector or other small
components, such as cameras, tools, etc., within the reactor vessel
without the activity being considered CORE ALTERATIONS. The potential
exists, however small, that an object can be dropped into the reactor
vessel. However, the justification for this change, is that the insertion of small components into the reactor vessel will have no effect on core reactivity since these items displace a small volume of
borated water, and sufficient borated water will surround the
components and provide the necessary neutron absorption to
neutronically isolate the components from the reactor. The
consequences
of dropping one of these small components into the vessel are bounded
by the In-Containment Fuel Handling Accident Analysis discussed in
Chapter 14.2.1 of the Turkey Point Updated Final Safety Analysis
Report (UFSAR). Therefore, the proposed change is bounded by the current and
the proposed In-Containment Fuel Handling Accident Analyses and will
not involve a significant increase in the probability or consequences of an accident previously evaluated.
The proposed change to TS 3.9.4 would allow the containment
personnel airlock (PAL) doors to be open during fuel movement and core
alterations. Currently, a single PAL door is closed during fuel
movement and core alterations to prevent the escape of radioactive
material in the event of a in-containment fuel handling accident. The
PAL is not an initiator of an accident. Whether the PAL doors are open
or closed during fuel movement and core alterations has no affect on
the probability of any accident previously evaluated.
Allowing the PAL doors to be open during fuel movement and core
alterations does not increase the consequences from a fuel handling
accident. The calculated offsite doses are well within the limits of
10 CFR Part 100. In addition, the calculated doses are larger than the
expected doses because the calculation does not incorporate the
closing file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (13 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval of the PAL door after the containment is evacuated. The proposed change should significantly reduce the dose to workers in containment in the event of a fuel handling accident by reducing the time required to evacuate the containment. The proposed change will also significantly
decrease the wear on the PAL doors and, consequently, increase the
availability of the PAL doors in the event of an accident.
The proposed change to the footnote of TS 3.9.4 is administrative in nature, and does not involve a significant increase in the
probability or consequences of an accident previously evaluated.
The changes being proposed do not affect assumptions contained in
plant safety analyses or the physical design of the plant, nor do they
affect Technical Specifications that preserve safety analysis
assumptions. Therefore, operation of the facility in accordance with the proposed amendments would not involve a significant increase in the probability or consequences of an accident previously analyzed.
(2) Operation of the facility in accordance with the proposed
amendments would not create the possibility of a new or different kind
of accident from any accident previously evaluated.
The change in the definition of CORE ALTERATIONS would allow the
movement of a temporary source range detector or other small
components, such as cameras, tools, etc., within the reactor vessel
without the activity being considered CORE ALTERATIONS. The potential
exists however small, that an object can be dropped into the reactor
vessel. However, the justification for this change, is that the
insertion of small components into the reactor vessel will have no effect on core reactivity since these items displace a small volume of
borated water, and sufficient borated water will surround the
components and provide the necessary neutron absorption to
neutronically isolate the components from the reactor. The
consequences
of dropping one of these small components into the vessel are bounded
by the In-Containment Fuel Handling Accident Analysis discussed in
Chapter 14.2.1 of the Turkey Point UFSAR. Therefore the proposed
change is bounded by the current and the proposed In-Containment Fuel
Handling Accident Analyses and will not create the possibility of a new or
different kind of accident.
The proposed change to Specification 3.9.4 affects a previously
evaluated accident, i.e., in-containment fuel handling accident. Both
the current and the proposed In-Containment Fuel Handling Accident file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (14 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval Analysis assume that all of the iodines and noble gases that become airborne within the containment escape and reach the site boundary and
low population zone with no credit taken for the containment building barrier or for decay or deposition taken. Since the proposed change does not involve the addition or modification of equipment nor does it
alter the design of plant systems and the revised analysis is
consistent with the current In-Containment Fuel Handling Accident
Analysis, the proposed change does not create the possibility of a new or different kind of accident from any accident previously evaluated.
The proposed change to the footnote of TS 3.9.4 is administrative
in nature and does not create the possibility of a new or different
kind of accident from any accident previously evaluated.
(3) Operation of the facility in accordance with the proposed
amendments would not involve a significant reduction in a margin of safety. The change in the definition of CORE ALTERATIONS would allow the
movement of a temporary source range detector or other small
components, such as cameras, tools, etc., within the reactor vessel
without the activity being considered CORE ALTERATIONS. The potential
exists however small, that an object can be dropped into the reactor
vessel. However, the justification for this change, is that the
insertion of small components into the reactor vessel will have no effect on core reactivity since these items displace a small volume of
borated water, and sufficient borated water will surround the
components and provide the necessary neutron absorption to
neutronically isolate the components from the reactor. The
consequences of dropping one of these small components into the vessel are bounded
by the Fuel Handling Accident Analysis discussed in Chapter 14.2.1 of
the Turkey Point UFSAR. Therefore, the proposed change is bound by the
current In-Containment Fuel Handling Accident Analyses and as a result
will not involve a significant reduction in a margin of safety.
The margin of safety as defined by 10 CFR Part 100 has not been
reduced. There is no increase in calculated offsite dose resulting
from a fuel handling accident in containment and the calculated dose is a
small fraction of the limits given in 10 CFR Part 100. The proposed
changes do not alter the bases for assurance that safety-related
activities are performed correctly or the basis for any Technical
Specification that is related to the establishment of or maintenance
of a safety margin. Therefore, operation of the facility in accordance
with the proposed amendments would not involve a significant reduction file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (15 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval in a margin of safety.
The proposed change to the footnote of TS 3.9.4 is administrative
in nature and does not relate to or modify the safety margins defined in, and maintained by, the Technical Specifications.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Florida Power and Light Company Docket Nos. 50-250 and 50-251
Turkey Point Plant, Units 3 and 4, Dade County, Florida.
Date of amendment request: October 20, 1994.
Description of amendment request: This supersedes the licensee's
original request dated July 19, 1994, and noticed in the Federal
Register on August 3, 1994 (59 FR 39588). The licensee proposes to
change Turkey Point, Units 3 and 4 Technical Specifications (TS)
4.8.1.1.2e. and 4.8.1.1.2f., which address Emergency Diesel Generator (EDG) fuel oil testing, by replacing the specific EDG fuel oil Surveillance Requirements with the requirement to verify new and
stored EDG fuel oil in accordance with the Diesel Fuel Oil Testing Program.
In addition, the licensee proposes the addition of ACTION statements g.
and h., to TS 3.8.1.1, to address the required action in the event the
diesel fuel oil does not meet the Diesel Fuel Oil Testing Program
limits. The Diesel Fuel Oil Testing Program will be described in both
TS 6.8.4 and the BASES Section to the Technical Specifications. In
addition, FPL proposes revising TS 6.8.1 to include the requirement
that written procedures shall be established, implemented and
maintained for implementation of the Diesel Fuel Oil Testing Program.
Basis for proposed no significant hazards consideration
determination: 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:
file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (16 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval (1) Operation of the facility in accordance with the proposed amendments would not involve a significant increase in the probability
or consequences of an accident previously evaluated.
The proposed changes to the Technical Specifications will permit the Technical Specification required testing of Emergency Diesel
Generator (EDG) fuel oil in accordance with the Turkey Point, Units 3
and 4 Diesel Fuel Oil Testing Program. The proposed change will permit
FPL to use more recent editions of the American Society for Testing and Materials (ASTM) standards currently listed in Technical Specification
Surveillance Requirements 4.8.1.1.2e. and 4.8.1.1.2f. Prior to
changing the Diesel Fuel Oil Testing Program, the proposed change will be
evaluated pursuant to Title 10 Code of Federal Regulations Sec. 50.59 (10 CFR Sec. 50.59), ``Changes, tests, and experiments. Title 10 CFR Sec. 50.59 permits a licensee to make changes in the procedures as
described in the safety analysis report without prior Commission
approval, provided that the proposed changes does not involve an
unreviewed safety question.
Title 10 CFR Sec. 50.59(a)(2) states that a proposed change
involves an unreviewed safety question (i) if the probability of
occurrence or the consequences of an accident or malfunction of
equipment important to safety previously evaluated in the safety
analysis report may be increased. Consequently, since any change to
the Diesel Fuel Oil Testing Program, including the ASTM standard or ASTM
edition standard to be used to evaluate EDG fuel oil acceptability, the change must be evaluated relative to the more restrictive evaluation
criterion of 10 CFR Sec. 50.59, then operation of the facility in
accordance with the proposed amendments would not involve a
significant
increase in the probability or consequences of an accident previously
evaluated. The EDG fuel oil TS Surveillance Requirements will be
replaced with a requirement to test the EDG fuel oil in accordance
with the Turkey Point Units 3 and 4 Diesel Fuel Oil Testing Program.
ACTION statement g. of TS 3.8.1.1 is added to address the required
action in the event the new fuel oil properties do not meet the Diesel
Fuel Oil Testing Program limits. A failure to meet the American
Petroleum Institute (API) gravity, kinematic viscosity, flash point or
clarity limits is cause for rejecting the new fuel oil prior to the
addition to the Diesel Fuel Oil Storage Tanks, but does not represent file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (17 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval a failure to meet the Limiting Condition for Operation (LCO) of TS
3.8.1.1, since the new fuel oil has not been added to the storage tanks. Provided these new fuel oil properties are met subsequent to the addition of the new fuel oil to the storage tanks, 30 days is provided
to complete the analyses of the other fuel oil properties specified in
Table 1 of ASTM-D975-81, except sulfur which may be performed in accordance with ASTM-D1552-79 or ASTM-D2622-82. In the event the other
new fuel oil properties specified in Table 1 of ASTM-D975-81 are not
met, ACTION statement g. of TS 3.8.1.1 provides an additional 30 days
to meet the Diesel Fuel Oil Testing Program limits. This additional 30
day period is acceptable because the fuel oil properties of interest, even if they are not within limits, would not have an immediate effect on EDG operation.
ACTION statement h. of TS 3.8.1.1 is added to address the required
action in the event the stored fuel oil total particulates do not meet
the Diesel Fuel Oil Testing Program limits. Fuel oil degradation
during long term storage shows up as an increase in particulate, due mostly
to oxidation. The presence of particulate does not mean the fuel oil will
not burn properly in a diesel engine. The frequency for performing
surveillance on stored fuel oil is based on stored fuel oil
degradation
trends which indicate that particulate concentration is unlikely to
change significantly between surveillances.
Prior to changing the Turkey Point Units 3 and 4 Diesel Fuel Oil
Testing Program, FPL will need to determine if the proposed program
change is at least as, if not more, effective, in detecting
unsatisfactory fuel oil. The EDGs will thus continue to function as
designed and the probability or consequences of previously evaluated
accidents will be unaffected.
(2) Operation of the facility in accordance with the proposed
amendments would not create the possibility of a new or different kind
of accident from any accident previously evaluated.
The proposed changes to the Technical Specifications will permit
the Technical Specification required testing of Emergency Diesel
Generator fuel oil using more recent editions of the American Society
for Testing and Materials (ASTM) standards currently listed in
Technical Specification Surveillance Requirements 4.8.1.1.2e. and
4.8.1.1.2f. Prior to changing the edition of the previously approved
ASTM standard being used to evaluate the EDG fuel oil, the proposed file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (18 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval edition standard will be evaluated pursuant to 10 CFR Sec. 50.59, ``Changes, tests, and experiments. Title 10 CFR Sec. 50.59 permits a

10 CFR Sec. 50.59(a)(2) states that a proposed change involves an
unreviewed safety question (ii) if a possibility for an accident or
malfunction of a different type than any evaluated previously in the safety analysis report may be created. Consequently, since any change
to the edition of the ASTM standard to be used to evaluate EDG fuel
oil acceptability must be evaluated relative to the more restrictive
evaluation criterion of 10 CFR Sec. 50.59, then operation of the
facility in accordance with the proposed amendments would not create the possibility of a new or different kind of accident from any accident previously evaluated.
ACTION statement g. of TS 3.8.1.1 is added to address the required

Table 1 of ASTM-D975-81 are not met, ACTION statement g. of TS 3.8.1.1
provides an additional 30 days to meet the Diesel Fuel Oil Testing
Program limits. This additional 30 day period is acceptable because
the fuel oil properties of interest, even if they are not within limits, would not have an immediate effect on EDG operation.
ACTION statement h. of TS 3.8.1.1 is added to address the required
action in the event the stored fuel oil total particulates does not
meet the Diesel Fuel Oil Testing Program limits. Fuel oil degradation
during long term storage shows up as an increase in particulate, due
mostly to oxidation. The presence of particulate does not mean the

degradation trends which indicate that particulate concentration is unlikely to change significantly between surveillances.
Prior to changing the Turkey Point Units 3 and 4 Diesel Fuel Oil
Testing Program, FPL will need to determine if the proposed program
change is at least as, if not more, effective, in detecting
unsatisfactory fuel oil. Since the proposed changes do not involve a change in the design of any plant system or component, and since the
proposed changes will need to evaluate the effect of any ASTM standard
edition change on the level of EDG reliability, the change proposed
will not create the possibility of a new or different kind of accident
from any accident previously evaluated.
(3) Operation of the facility in accordance with the proposed amendments would not involve a significant reduction in a margin of safety.
The proposed changes to the Technical Specifications will permit
the Technical Specification required testing of Emergency Diesel
Generator (EDG) fuel oil using more recent editions of the American

edition standard will be evaluated pursuant to 10 CFR Sec. 50.59,
``Changes, tests, and experiments. Title 10 CFR Sec. 50.59 permits a
licensee to make changes in the procedures as described in the safety
analysis report without prior NRC approval, provided that the proposed changes does not involve an unreviewed safety question. Title 10 CFR
Sec. 50.59(a)(2) states that a proposed change involves an unreviewed
safety question (iii) if the margin of safety as defined in the basis
for any technical specification is reduced. Consequently, since any

of the facility in accordance with the proposed amendments would not

change is at least as, if not more, effective, in detecting unsatisfactory fuel oil. Since the proposed changes will require a
safety evaluation to assure that the reliability of the EDGs using
fuel oil tested in accordance with the different ASTM standard edition
maintains the current margin of safety, the proposed changes do not
involve a reduction in a margin of safety.

Docket No. 50-302 Crystal River Nuclear Generating Plant, Unit No. 3, Citrus County, Florida.
Date of amendment request: September 30, 1994.
Description of amendment request: The proposed amendment would revise the Crystal River 3 (CR3) Nuclear generating Plant Technical
Specifications (TS) to allow an increase in the rated thermal power (RTP) for CR-3 from the current 2544 level to 2568 Megawatt thermal (Wt). Accordingly, in TS 1.1, ``Definitions, would be revised to
indicate the new power level of 2568 MWt. The proposed change would
not require any hardware modifications.
Basis for proposed no significant hazards consideration
determination: Currently, CR-3 is operating at a maximum RTP of 2544
MWt. The licensee proposes to operate at a maximum RTP of 2568 MWt, an
increase of 24 MWt over the current licensed power of 2544 MWt.
The licensee states that the Babcock and Wilcox (B&W) 177 Fuel
Assembly (FA) Nuclear Steam Supply System (NSSS) in the CR3 design is
capable of operating at a thermal power level of 2772 MWt. Due to
limitations in the secondary area of the plant, the licensee requests
authorization to operate at 2568 MWt which is less than the design
level of 2772 MWt. The licensee performed a detailed engineering study
on this power increase.
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. Operation of the facility in accordance with the proposed
amendment would not involve a significant increase in the probability
of occurrence or consequences of an accident previously evaluated. The
thermal-hydraulic and nuclear characteristics of the reactor core were
originally designed for a rated thermal power of 2568 MWt or higher.
Therefore, the proposed thermal power increase to the reference power
level of 2568 MWt does not change the original design assumptions and
analyses for the reactor core. Most of the design basis accidents and
transients were originally evaluated at the proposed power level. As
described more fully in this submittal, those transients and accidents
that were not originally evaluated at 2568 MWt were re-evaluated using
CR-3 FSAR [Final Safety Analysis Report] Chapter 14 accident sequence file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (22 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval of events, reactor protection criteria, and approved calculational methods. Based on this evaluation and initial plant design
evaluations, FPC [Florida Power Corporation, the licensee for CR3] has determined that the probability and consequences of design basis transients and
accidents are not significantly increased and that the radiological
consequences from the design basis transients and accidents remain
well below 10 CFR 100 limits.
FPC has also reviewed CR-3 balance of plant and safety related
systems to determine which systems and components could be affected by
the proposed power increase. The changes to the reactor coolant system
and secondary conditions and parameters are discussed in this
submittal. These changes are minor in nature. The only Technical Specification change is to revise the reference power to 2568 MWt.
No facility modifications will be required. FPC evaluated the systems and
components and concluded that these systems and components will
continue to perform within their design parameters with the unit
operating at 2568 MWt.
Based on the foregoing, the proposed amendment does not
significantly increase the probability or consequences of an accident
previously evaluated.
- 2. The proposed thermal power increase does not create the
possibility of a new or different kind of accident from previously
evaluated accidents. As noted above, the thermal-hydraulic and nuclear
characteristics of the reactor core were originally designed for
operation at the proposed thermal power. Therefore, operation at the proposed power level does not introduce new or different performance
characteristics that create the possibility of a new or different kind
of accident.
FPC has also reviewed CR-3 safety-related systems and balance of
plant systems to determine which systems could be affected by the
proposed power increase and the resultant minor changes in plant
parameters and operating conditions. Systems that could be affected
were evaluated using the licensing basis criteria described in the CR-
3 FSAR to assure their adequacy at the increased power level. Included
in these evaluations were plant features that are not power level related
or directly affected by an increase in power level, as well as, associated issues such as environmental considerations. Equipment
performance and plant operation were evaluated with respect to actual
performance versus projected operating conditions to identify any file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (23 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval hardware modifications required to achieve the upgraded power. Based on this evaluation, FPC has determined that all systems will continue to perform within their design parameters at 2568 MWt and that no physical modifications to these systems will be necessary to accommodate a 2568
MWt rating. Only minor re-calibration of plant instrumentation to
reflect the increased power will be needed. The proposed power level does not introduce any new performance characteristics or modes of
operation for plant systems and components, and does not introduce any
new failure modes.
Based on the foregoing, the proposed amendment does not create the
possibility of a new or different kind of accident.
- 3. The proposed amendment does not involve a significant reduction in a margin of safety. The thermal-hydraulic and nuclear characteristics of the reactor core were originally designed for
operation at the proposed power level. Most of the design basis
transients and accidents were originally analyzed assuming a power
level of 2568 MWt or higher. As described more fully in this
submittal, those transients and accidents that were not originally analyzed at
2568 MWt were re-evaluated using CR-3 FSAR Chapter 14 accident
sequence of events, reactor protection criteria, and approved calculational
methods. FPC has determined that operation with the proposed thermal
power will be bounded by the original analyses. In addition, FPC's
evaluation of affected plant systems and components revealed that plant systems and components will continue to operate within their design
parameters with no significant change in a margin of safety.
Based on the foregoing, the proposed amendment does not involve a
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 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Donald C. Cook Nuclear Plant, Unit Nos. 1 and 2, Berrien County, Michigan.
Date of amendment request: August 3, 1994.
Description of amendment requests: The proposed amendments would allow the radiological effluent technical specifications (TS) to be
relocated to other controlled documents. Procedural details contained
in the current radiological effluents TS have been relocated to either
the Offsite Dose Calculation Manual (OCDM) or the Process Control
Program (PCP), as applicable. Proposed revisions to the OCDM and PCP
have been prepared in accordance with the proposed changes to the administrative controls section of the TS.
Basis for proposed no significant hazards consideration
determination: 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:
Criterion 1
The changes described above in no way negatively impact the
requirements of the T/Ss. Separating the turbine room sump releases
from the others is purely a clarification of the method we handle
releases. The six ground monitoring wells added to the T/S table
updates our current monitoring practice. With the six extra wells to
monitor, we exceed the monitoring requirements of the T/Ss. Therefore, it is concluded that the proposed changes do not involve a significant increase in the probability or consequences of an accident previously
evaluated.
Criterion 2
No changes to the LCOs for either T/S are proposed as part of this
amendment request. The proposed change does not involve any physical
changes to the plant or any changes to plant operations. The changes
merely propose to update our methods of implementing the T/S with our
current practices. Thus, the proposed change does not create the
possibility of a new or different kind of accident from any accident
previously evaluated.
Criterion 3
The changes described above in no way negatively impact the
requirements of the T/Ss. Separating the turbine room sump releases
from the others is purely a clarification of the method we handle
releases. The six ground monitoring wells added to the T/S table
updates our current monitoring practice. With the extra wells to file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (25 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval monitor, we exceed the monitoring requirements called for in the T/Ss.
Therefore, it is concluded that the proposed changes do not involve a
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 requests involve no significant hazards consideration.

Niagara Mohawk Power Corporation Docket No. 50-410 Nine Mile Point Nuclear Station, Unit 2, Oswego County, New York.
Date of amendment request: October 5, 1994.
Description of amendment request: The proposed license amendment
would revise the applicability requirements of Technical Specification (TS) 3.7.3 to require operability of the Control Room Outdoor Air
Special Filter Train System in Operational Conditions 1, 2, 3 and **
(when irradiated fuel is being handled in the reactor building and
during CORE ALTERATIONS and operations with a potential for draining the reactor vessel and uncovering irradiated fuel) rather than in all
Operational Conditions and * * *. The applicability requirements for
Action Statement b of TS 3.7.3 and for the Radiation Monitoring
Instrumentation required operable by TS Tables 3.3.7.1-1 and 4.3.7.1-1
would be changed in a similar manner. The proposed amendment would
also add a notation to Action Statement b.1 of TS 3.7.3 stating that the
provisions of Specification 3.0.4 are not applicable provided an
operable control room filter train is in the emergency pressurization
mode of operation. The licensee stated that these proposed changes are
consistent with the requirements of the NRC's Improved Standard
Technical Specifications (NUREG-1433) and with Generic Letter 87-09,
``Section 3.0 and 4.0 of the Standard Technical Specifications (STS)

Basis for proposed no significant hazards consideration
determination: 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:
The operation of Nine Mile Point Unit 2, in accordance with the
proposed amendment, will not involve a significant increase in the
probability or consequences of an accident previously evaluated.
The Control Room Outdoor Air Special Filter Train System is not an
initiator or precursor to an accident. The Control Room Outdoor Air
Special Filter Train System responds to a release of radioactivity to
the outside environment as detected in the air supply to the control
room by providing a radiologically controlled environment within the
control room. In operational conditions 4 and 5, the probability and consequences of a design basis accident are reduced due to the pressure and temperature limitations in these operational conditions.
Therefore, maintaining the chiller subsystem operable is not required in
operational conditions 4 and 5, except for the * *
- operational
condition. Therefore, a change to applicability and action statements
of LCO [Limiting Condition For Operation] 3.7.3 cannot affect the
probability of a previously evaluated accident.
All accidents which take credit for operation of the Control Room
Outdoor Air Special Filter Train System in the emergency
pressurization
mode of operation are analyzed and presented in Chapter 15 of the USAR
[Updated Safety Analysis Report]. These accidents can only occur in
operational conditions 1, 2, 3 and * * *.
Accordingly, the proposed change in the applicability of LCO 3.7.3
from all operational conditions (i.e., 1, 2, 3, 4, 5 and * * *) to
operational conditions 1, 2, 3 and * *
- does not significantly
increase the consequences of an accident previously evaluated. The
proposed change to action statement b of LCO 3.7.3 and to Tables
3.3.7.1-1 and 4.3.7.1-1 of LCO 3.3.7.1 is consistent with the above
change.
Sections 15.7.4 and 15.7.5 of the USAR evaluate a fuel handling
accident and a spent fuel cask drop accident, respectively. The
radiological evaluation of these accidents considers the unfiltered
radioactivity that enters the control room prior to the automatic
operation of the Control Room Outdoor Special Filter Train System in
the emergency pressurization mode of operation. The radiological
consequences of these accidents are within the limits of GDC [General file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (27 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval Design Criterion]-19.
With one control room filter train inoperable and prior to
entering the operational condition, the proposed change to action statement b.1 of LCO 3.7.3 would require an operable control room filter train be
placed in the emergency pressurization mode of operation. During an
accident involving the release of radioactivity to the environment, an
operable control room filter train would already be running in the emergency pressurization mode and performing its safety function, thereby preventing the entry of unfiltered radioactivity into the
control room. Therefore, if a fuel handling accident or a spent fuel
cask drop accident were to occur and release radioactivity, the
control room personnel radiological doses would be less than the doses depicted in the USAR. Accordingly, the Technical Specification change to action
statement b.1 does not significantly increase the consequences of a
previously evaluated accident.
The operation of Nine Mile Point Unit 2, in accordance with the
proposed amendment, will not create the possibility of a new or
different kind of accident from any accident previously evaluated.
This amendment does not involve any accident precursors or
initiators. In addition, this amendment does not require any changes
to plant equipment.
During an accident involving the release of radioactivity to the
environment an operable control room filter train would already be running in the emergency pressurization mode and performing its safety
function. Furthermore, the operating status of a running control room
filter train would be unaffected by the receipt of an automatic start
signal due to high radiation in either air intake to the Control Room
Outdoor Air Special Filter Train System. Therefore, the proposed
amendment will not create the possibility of a new or different kind
of accident from any accident previously evaluated.
The operation of Nine Mile Point Unit 2, in accordance with the
proposed amendment, will not involve a significant reduction in a
margin of safety.
The proposed change in the applicability of LCO 3.7.3 from all
operational conditions (i.e., 1, 2, 3, 4, 5 and * * *) to operational
conditions 1, 2, 3 and * *
- is consistent with the safety analysis
contained in the USAR. The proposed changes to action statement b of
LCO 3.7.3 and to Tables 3.3.7.1-1 and 4.3.7.1-1 of LCO 3.3.7.1 is file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (28 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval consistent with the above change.
Entry into the ** operational condition for LCO 3.7.3 with one
control room filter train inoperable and the other control room filter train operable and operating in the emergency pressurization mode provides a comparable level of safety to two operable non-running
control room filter trains. The remedial measure prescribed by
Technical Specification action statement b.1 (placing an operable
control room filter train in the emergency pressurization mode of operation) for which the exception to LCO 3.0.4 is proposed provides a
sufficient level of protection to permit operational mode changes and
safe long-term operation of NMP2 [Nine Mile Point Unit 2] consistent
with the licensing basis described in the USAR. Therefore, the
proposed change to action statement b.1 is consistent with Generic Letter 87-09, ``Sections 3.0 and 4.0 of the Standard Technical Specifications (STS)
on the Applicability of Limiting Conditions for Operation and
Surveillance Requirements. Accordingly, this change will not
significantly reduce the margin of safety.
This proposed amendment is consistent with the Improved Standard
Technical Specifications, NUREG-1433. Accordingly, as determined by
the analysis above, this proposed amendment involves no significant
hazards consideration.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 50.92(c) are satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (29 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval Description of amendment request: The proposed amendment would add a footnote to Technical Specification (TS) 4.8.1.1.2.e.8 which would
permit performance of the 24-hour functional test of the emergency diesel generators (EDGs) during power operation. TS 4.8.1.1.2.e.8 currently requires the 24-hour functional test of the EDGs be
performed
at least once per 18 months during shutdown; the proposed amendment
would permit this testing to be performed during power operation provided the other two EDGs are operable. If either of the other two
EDGs become inoperable, the test would be aborted.
Basis for proposed no significant hazards consideration
determination: 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:
The operation of Nine Mile Point Unit 2, in accordance with the proposed amendment, will not involve a significant increase in the
probability or consequences of an accident previously evaluated.
The proposed change to permit the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> functional test of the
diesels to be performed during power operation does not increase the
chances for a previously analyzed accident to occur. The function of
the diesels is to supply emergency power in the event of a loss of
offsite power. Operation of the diesels is not a precursor to any
accident. Furthermore, the diesel generator being tested will remain
operable and will be available to supply emergency loads within the
required time. In addition, the two remaining diesel generators will
be operable during the test. Consequently, if an offsite disturbance were to occur that affected the operability of the diesel being tested, the
two remaining diesels would be capable of feeding the loads necessary
for safe shutdown of the plant. This addresses the concerns raised in
Information Notice 84-69 regarding the operation of emergency diesel
generators connected in parallel with offsite power. In summary, the
proposed changes do not adversely affect the performance or the
ability of the diesel generators to perform their intended function.
Therefore, the proposed change will not involve a significant
increase in the probability or consequences of an accident previously
evaluated.
The operation of Nine Mile Point Unit 2, in accordance with the
proposed amendment, will not create the possibility of a new or
different kind of accident from any previously evaluated.
The proposed amendment to the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> functional surveillance test
will not affect the operation of any safety system or alter its file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (30 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval response to any previously analyzed accident. The diesel will automatically transfer from the test mode if necessary to supply
emergency loads in the requried time. The test mode is used for the monthly surveillance of the diesel generators as well, therefore, no new plant operating modes are introduced. In the event the diesel
fails the functional test it will be declared inoperable and the actions
required for an inoperable diesel will be performed. The remaining two diesel generators will be operable and are capable of feeding the
loads necessary for safe shutdown of the plant.
Therefore, the proposed change will not create the possibility of
a new or different kind of accident from any previously evaluated.
The operation of Nine Mile Point Unit 2, in accordance with the proposed amendment, will not involve a significant reduction in a
margin of safety.
The proposed amendment will not reduce availability of the diesel
generator being tested to provide emergency power in the event of a
loss of offsite power. If a loss of offsite power or a loss of coolant
accident occurs during the surveillance test, the emergency bus would
de-energize and shed load. The diesel generator would then transfer
from the test mode to the emergency mode. It would then be available
to automatically supply emergency loads. In addition, the two remaining
generators will be operable during the test. Consequently, if an
offsite disturbance were to occur that affected the operability of the diesel begin tested, the two remaining diesels would be capable of
feeding the loads necessary for safe shutdown of the plant. The time
required for the diesel being tested to pick up emergency loads will
not be affected by performing the 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> functional test during power
operation.
Therefore, the proposed change will not involve a significant
reduction in a margin of safety.

Docket No. 50-336.
Millstone Nuclear Power Station, Unit No. 2, New London County, Connecticut.
Date of amendment request: October 18, 1994.
Description of amendment request: The proposed amendment would
require three type A overall Integrated Containment Leakage Tests be
conducted at approximately equal intervals during shutdowns during
each 10-year service period. For the third Type A test for the second 10-year period, it would be conducted during the thirteenth refueling
outage extending the second 10-year service period to the end of the
thirteenth refueling outage. The amendment would also change the
Containment Leakage Bases by reflecting the conditions of a proposed
exemption to 10 CFR 50, Appendix J, that would remove the requirement
that the third Type A test for each 10-year period be conducted when
the plant is shutdown for the 10-year plant inservice inspection.
Basis for proposed no significant hazards consideration
determination: 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:
- *
- The proposed changes do not involve a SHC [significant hazards consideration] because the change would not:
- 1. Involve a significant increase in the probability or
consequences of an accident previously analyzed.
Type A tests are performed to ensure that the total leakage from
containment does not exceed the maximum allowable primary containment
leakage rate at the design pressure. This ensures compliance with the
dose limits of 10 CFR 100.
The proposal to revise Surveillance Requirement 4.6.1.2.a of the
Millstone Unit No. 2 Technical Specifications will increase the
flexibility for scheduling the Type A tests. It does not modify the
maximum allowable leakage rate at the design containment pressure, does not impact the design basis of the containment, and does not make any
physical or operational changes to existing plant structures, systems, or components.
The first two Type A tests of the second 10-year service period file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (32 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval for Millstone Unit No. 2 have been conducted. The results of these tests
demonstrate that Millstone Unit No. 2 has maintained control of containment integrity by maintaining margin between the acceptance criterion and the ``As-Found and ``As-Left leakage rates.
Historically, Type A tests have a relatively low failure rate
where Type B and C testing (local leakage rate tests) could not detect the leakage path. Most Type A test failures are attributed to failures to
Type B or C components (containment penetrations and isolation
valves).
Type B and C components are tested per Surveillance Requirement
4.6.1.2.d for the Millstone Unit No. 2 Technical Specifications. These
tests are required to be conducted at intervals no greater than 24 months, and the acceptance criterion for the combined leakage rate for all penetrations and valves subject to the Type B and C tests is 0.6
L<INF>a. These local leakage rate tests provide assurance that
containment integrity is maintained. The relatively low ``As-Left
Type B and C total leakage resulting from the past outage indicates
that the leakage has been maintained within the technical
specification
acceptance criterion. The Type B and C tests will continue to be
performed in accordance with the requirements of Surveillance
Requirement 4.6.1.2.d. However, on September 26, 1994, NNECO submitted
a request for a one-time technical specification change, request for
enforcement discretion, and a request for a scheduler exemption from
Appendix J to 10 CFR 50 regarding the Schedule for Type B and C testing. The NRC verbally granted enforcement discretion on September
24, 1994, and written enforcement discretion on September 30, 1994.
The schedular exemption request was granted on October 12, 1994.
The previous Type A, B, and C tests demonstrate that Millstone
Unit No. 2 has maintained control of containment integrity by maintaining a
conservative margin between the acceptance criterion and the ``As-
Found and ``As-Left leakage results. Based on this, the Millstone
Unit No. 2 containment is considered to be in sound condition.
No operations are known to have occurred which would suggest any
substantial degradation of these results.
Based on the above, the proposal to revise Surveillance
Requirement
4.6.1.2.a of the Millstone Unit No. 2 Technical Specifications does
not file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (33 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval involve a significant increase in the probability or consequences of an accident previously analyzed.
- 2. Create the possibility of a new or different kind of accident from any previously analyzed.
The proposal to revise Surveillance Requirement 4.6.1.2.a of the
Millstone Unit No. 2 Technical Specifications will increase the
flexibility in scheduling the Type A tests. It does not make any physical or operational changes to existing plant structures, systems, or components. In addition, the proposal does not modify the
acceptance
criterion for the Type A tests. Maintaining the leakage through the
containment boundary to the atmosphere within a specific value ensures
that the plant complies with the requirements of 10 CFR 100. The containment boundary serves as an accident mitigator; it is not an accident initiator. Therefore, the proposal to revise Surveillance
Requirement 4.6.1.2.a does not create the possibility of a new or
different kind of accident from any previously analyzed.
- 3. Involve a significant reduction in the margin of safety.
The proposal to revise Surveillance Requirement 4.6.1.2.a of the
Millstone Unit No. 2 Technical Specifications will increase the
flexibility for scheduling the Type A tests. It does not modify the
maximum allowable leakage rate at the design containment pressure, does not impact the design basis of the containment, and does not make any
physical or operational changes to existing plant structures, systems, or components.
The first two Type A tests of the second 10-year service period
for Millstone Unit No. 2 have been conducted. The results of these tests
demonstrate that Millstone Unit No. 2 has maintained control of
containment integrity by maintaining margin between the acceptance
criterion and the ``As-Found and ``As-Left leakage rates.
Additionally, the results of the last Type B and C tests had
significant margin with respect to the acceptance criterion. Based on
the previous Type A, B, and C tests, the Millstone Unit No. 2 containment is considered to be in sound condition.
No operations are
known to have occurred which would suggest any substantial degradation
of these results.
Based on the above, the proposal 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) file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (34 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval are satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Description of amendment request: The licensee has proposed to
revise the Technical Specifications (1) to clarify the definition of
core alterations, (2) to change the verbiage in the Limiting Condition
For Operation (LCO) addressing the refueling operations, (3) to make
changes to three surveillance requirements involving source range
instrumentation, and (4) to change the LCO regarding the Residual heat
Removal and coolant circulation water levels to be consistent with the
guidance provided in NUREG-1431.
Basis for proposed no significant hazards consideration
determination: 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:
The proposed changes do not involve an SHC [significant hazards
consideration] because the changes would not:
- 1. Involve a significant increase in the probability or
consequences of an accident previously evaluated.
Boron Dilution in Mode 6--A boron dilution in Mode 6 is precluded
by technical specification requirements to close and lock all dilution
source valves. There is a provision for dilution valves to be opened
under administrative controls; in this case, cautionary measures will
be taken to control and monitor the reactivity addition. Deletion of
the source range analog operational test prior to core alterations
will not impact an accident previously evaluated since the sources range file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (35 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval monitors are verified operable prior to entry into Mode 6 and every 7 days thereafter. The change in definition for a core alteration means
that components which do not effect reactivity may be moved within the reactor vessel without any additional condition such as direct supervision of an SRO.
Since a boron dilution would not be initiated by movement of
nonfuel components within the reactor vessel, it is not impacted by
the change in definition of a core alteration.
Inadvertent Loading of a Fuel Assembly--Movement of a fuel
assembly would be performed as a core alteration under the supervision of an
SRO, therefore, it would not be impacted by the change to the
definition of a core alteration. The change to the source range monitors also will not affect the probability of occurrence of a misloaded fuel assembly since this accident is precluded by
administrative controls, as well as the source range monitors. Also, there will be no degradation in the reliability or accuracy of the
source range monitors due to this change. The deletion of the
requirement to perform the analog channel operational test within
eight hours prior to core alterations will not impact performance of the
monitors, since they have to be checked prior to entry into Mode 6 and
every 7 days thereafter.
Fuel Handling Accident--Movement of fuel will not affect this
accident, because it will still be considered a core alteration.
Therefore, there is no effect on the probability of a fuel handling accident. The source range monitors are not involved in the occurrence
of a fuel handling accident. The fuel handling accident is the only
accident considered here with radiological consequences. It will not
be impacted by the proposed changes.
Loss of RHR in Mode 6--The probability of this accident will not
be changed since the new requirement is the same as before. As before, RHR may be secured for up to one hour per eight-hour period and boron
dilution operations may not be performed with RHR secured (although
this requirement is being added to the notes, the requirement is also
given elsewhere in the technical specifications). Additionally, the
existing reactor coolant system (RSC) temperature limits must still be
met.
Based on the above, the proposed changes do not involve a file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (36 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval significant increase in the probability or consequences of an accident previously evaluated.
- 2. Create the possibility of a new or different kind of accident from any previously analyzed.
All required systems will continue to operate as before.
Therefore, there is no possibility of a new or different kind of accident. The
deletion of the source range analog channel operational test within eight hours prior to core alterations will not affect the performance
of the monitors since they will have had this test completed prior to
entry into Mode 6 and every 7 days thereafter. The change in
definition
of a core alteration cannot create the possibility of a new type of
accident because those initiating events for accidents will remain classified as core alterations.
- 3. Involve a significant reduction in the margin of safety.
The margin of safety for the above listed accidents will remain as
before.
- a. Boron dilution in Mode 6--This accident calculates the time
from receipt of a shutdown margin monitor dilution alarm until the core
reaches criticality. Since this time is not changed, there is no reduction in the margin of safety. In this case, the dilution is
precluded by administrative controls which will not be impacted by the
proposed changes.
- b. Inadvertent Loading of a Fuel Assembly--Technical Specification
3.9.1.1 protects against this accident by requiring sufficient boron in the RCS to prevent criticality for any core configuration including
two stuck RCCAs [rod cluster control assemblies] in the fully withdrawn
position. Since this requirement will not change, the margin of safety
will not change.
- c. Fuel Handling Accident--The margin of safety for the
radiological limits is not changed.
- d. Loss of RHR--Changes are editorial due to the revised
definition
of a core alteration. There is no change to the margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on

Prairie Island Nuclear Generating Plant, Unit Nos. 1 and 2, Goodhue County, Minnesota.
Date of amendment requests: October 3, 1994.
Description of amendment requests: The proposed amendment would
revise Prairie island Nuclear Generating Plant Technical Specification
4.6, ``Periodic Testing of Emergency Power Systems. Specifically, the proposed amendment would modify the emergency diesel generator (EDG)
24-hour load test requirements to provide a indicated load range of
103-110% of the continuous rating. The proposed amendment would also
rephrase various EDG test requirements to provide clarity and delete
the requirement to verify that the auto-connected loads do not exceed
3000 kw (Unit 2 5100kw).
Basis for proposed no significant hazards consideration determination: 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. The proposed amendment will not involve a significant increase
in the probability or consequences of an accident previously evaluated.
Changing the specification from ``unit to ``diesel generator
does not change the intent of the specification, it merely clarifies
the original intent and therefore cannot involve a change in the
probability or consequences of an accident.
Changing the 22-hour lower range limit from a load of 90% to an
indicated load of 92% removes possible ambiguity from the
specification
but does not change the actual requirement, therefore it cannot
involve a change in the probability or consequences of an accident.
file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (38 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval Removing the 22-hour upper range limit from the specification does not reduce the conservatism of the test since operating at a higher
load provides more evidence of the ability of the machine to carry the accident loads. For this reason, this change will not involve any increase in the consequences of an accident. Also, increasing the load
at which the diesel generator is tested cannot affect the probability
of an accident.
The NRC staff has pointed out, in Generic Letter 88-15, the hazards of testing the Diesel Generator at a load greater than the design
rating. The proposed change is intended to ensure that the design
rating is not inadvertently exceeded. Since the recent installation of
two additional emergency diesel generators, the highest anticipated
event loads are: Unit 1-2414kW, Unit 2-3813 kW. For these diesel generators, then, 103% of the continuous ratings:
<bullet> Unit 1, 103% of 2750 kW (continuous rating) = 2832.5 kW
represents 117.3% of the highest anticipated event load and;
<bullet> Unit 2, 103% of 5400 kW (continuous rating) = 5562 kW
represents 145.9% of the highest anticipated event load.
A test load of 103%, therefore would still be significantly
greater than the load required during accident conditions. Since an adequate
level of electrical load carrying capacity of the diesel generators (and thus their accident mitigating functions) would still be
demonstrated by the surveillance test, the consequences of an accident
would be unaffected by the proposed change. The probability of
occurrence of a previously evaluated accident would be unaffected since testing a diesel generator at load between 103 and 110 percent instead
of at load between 105 and 110 percent could not cause or contribute
to the initiation of an accident. For these reasons, this change could
have no effect on the probability or consequences of an accident
previously evaluated.
Allowing momentary transients outside of the test band does not
affect the conduct of the test, it merely allows momentary swing
outside the specified band to not invalidate the test. Not allowing
momentary transients would not prevent them, it would only require
conducting the test longer until the specified time period was
achieved without moving outside the band. Since the machine will not be
operated any differently, this specification change cannot affect the file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (39 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval probability or consequences of an accident previously evaluated.
Proposed changes A, B, C, D, and the first part of E [identified
as such in the submittal] are intended to clarify the meaning of the existing specifications without changing the requirements. For this
reason, these proposed changes to the Technical Specifications will
not change the manner in which the plant is operated or maintained. These administrative changes, therefore, will effect on the probability or
consequences of an accident previously evaluated.
The second part of E (verification of the bypass of diesel
generator trips during a simulated safety injection signal vs
concurrent safety injection and loss of offsite power signals) does
not change the intended function which is to be tested but, rather, reduces the special conditions (temporary electrical jumpers to simulate the
loss of offsite power) in which the plant needs to be placed in order
to perform the test.
Proposed change F (removal of the verification that the auto-
connected load do not exceed 3000 or 5100 kW) does not reduce the
assurance of the ability of the diesel generators to perform the
accident mitigation functions since this verification is performed by
other, more pertinent, means.
Therefore, these changes cannot increase the probability or
consequences of an accident previously evaluated.
- 2. The proposed amendment will not create the possibility of a new or different king of accident from any accident previously analyzed.
Changing the specification from ``unit to ``diesel generator
does not change the intent of the specification, it merely clarifies
the original intent and therefore cannot create the possibility of a
new or different kind of accident.
Changing the 22-hour lower range limit from a load of 90% to an
indicated load of 92% removes possible ambiguity from the
specification
but does not change the actual requirement.
Removing the 22-hour upper range limit from the specification does
not change the manner in which the surveillance is performed. It only
affects whether the time spent above 100% load can be counted toward
22 hours2.546296e-4 days <br />0.00611 hours <br />3.637566e-5 weeks <br />8.371e-6 months <br /> in the 22-hour portion of the test. This change would not allow
any new modes of operation nor does it allow any modification to the
plant.file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (40 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval As stated above, testing a diesel generator at a load between 103 and 110% instead of between 105 and 110% could not cause or contribute
to the initiation of an accident.
Allowing momentary transients outside of the test band does not affect the conduct of the test, it merely allows momentary swings
outside the specified band to not invalidate the test. Not allowing
momentary transients would not prevent them, it would only require
conducting the test longer until the specific time period was achieved without moving outside the band.
Therefore, for these reasons, operation of the facility in
accordance with the proposed amendment will not create the possibility
of a new or different kind of accident from any accident previously
analyzed.
As stated above [for changes A-F], the proposed changes will not cause a change in the way in which the plant is operated or maintained, excepted for the reduction of the special conditions in which the
plant needs to be placed in order to test the bypass of the diesel generator
trips. Therefore, these administrative changes will not create the
possibility of a new or different kind of accident from any accident
previously analyzed.
- 3. The proposed amendment will not involve a significant reduction
in a margin of safety.
Changing the specification from ``unit to ``diesel generator
does not change the intent of the specification, it merely clarifies
the original intent and therefore cannot affect the margin of safety.
Changing the 22-hour lower range limit from a load of 90% to an
indicated load of 92% removes possible ambiguity from the
specification
but does not change the actual requirement and therefore cannot affect
the margin of safety.
The margin of safety is not affected by removal of the 22-hour
upper range limit on the operation of the diesel generators during
surveillance testing since the margin of safety is related to the
magnitude of the accident loads and the maximum capacity of the
machine to carry load and this margin would be unaffected by this change.
The capacity of each diesel generator to carry electrical load can
not be diminished by being tested at a lower load. Also, load testing
to less than 105% but more than 103% does not lessen the confidence in
the ability of the diesel generators to carry adequate load for this
facility since these diesel generators have significantly greater load file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (41 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval capacity than required by Standard Review Plan guidance in this regard (the guidance allows peak accident load up to 100% of the continuous
rating versus Unit 1 diesel generators peak accident load of 87.8% and Unit 2 diesel generators peak accident load of 70.6%). Therefore, this change will not involve a significant reduction in the margin of
safety.
Allowing momentary transients outside of the test band does not
affect the conduct of the test, it merely allows momentary swings outside the specified band to not invalidate the test. Not allowing
momentary transients would not prevent them, it would only require
conducting the test longer until the specified time period was
achieved without moving outside the band. Since the machine will not be
operated any differently per the new specification, the margin of safety is unaffected.
As stated above [for changes A-F], the proposed changes will not
cause a change in the way in which the plant is operated or
maintained, except for the reduction of the special conditions in which the plant
needs to be placed in order to test the bypass of the diesel generator
trips. Therefore, these administrative change will not involve a
significant reduction in a margin of safety.

Description of amendment request: The proposed amendment to the file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (42 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval Technical Specifications (TSs) would (1) delete the surveillance requirements contained in TS 3.6(3)a for the raw water backup valves
to the containment cooling coils, (2) delete the surveillance requirements
contained in TS 3.2, Table 3-5, item 6, for raw water valves, and (3)
revise the basis of TS 2.4 to reflect these changes.
Basis for proposed no significant hazards consideration determination: 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) The proposed changes do not involve a significant increase in
the probability or consequences of an accident previously evaluated.
The deletion of surveillance requirements contained in Technical Specifications (TS) 3.2, Table 3-5, Items 6 and 3.6(3)a does not involve a significant increase in the probability or consequences of
an accident previously evaluated.
TS 3.6(3)a requires the Raw Water (RW) backup valves to the
containment air coolers to be tested each refueling outage. In 1990, during the process of reviewing several open items created by the
design basis reconstitution project, an engineering analysis
determined
that RW direct cooling of the containment air cooling coils should not
be used after an accident that has created elevated temperature
conditions inside containment. The high containment air temperatures, in conjunction with the low back pressure in the containment cooling coils when in the RW direct cooling mode, introduces the possibility
of vaporization inside the coils. Therefore, the use of RW direct cooling
for the containment air coolers has been discontinued in post-Loss of
Coolant Accident (LOCA) or post-Main Steam Line Break (MSLB)
situations. The issue of not being able to utilize RW direct cooling
to the containment air cooling coils was reported to the NRC in LER 25, dated October 29, 1990 and LER-90-25 Revision 1, dated December 17, 1990.
Raw water direct cooling of the containment air coolers is
possible if the containment atmospheric temperatures are less that 150 deg.F.
If RW direct cooling of the containment air coolers was utilized after a file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (43 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval LOCA or MSLB accident, it could only be used for long-term containment atmospheric cooling. These conditions are essentially equivalent to
that associated with conditions in containment during normal plant operation. RW direct cooling of the containment air coolers is not a required post-accident function to maintain containment pressure below
60 psig. Since these valves are not required to perform a post-
accident function, deletion of the requirements to test these valves does not involve a significant increase in the probability or consequences of
an accident previously evaluated.
TS 3.2, Table 3-5, Item 6 requires that valves in the RW system be
tested every refueling outage. The valves tested by this surveillance
that could perform a safety function are already tested in accordance with TS 3.3(1). Therefore testing of these valves under TS 3.2, Table 3-5, Item 6 is redundant to TS 3.3(1)a.
(2) The proposed changes do not create the possibility of a new or
different kind of accident from any previously analyzed.
There will be no physical alterations to the plant configuration, changes to setpoint values, or changes to the implementation of
setpoints or limits as a result of this proposed change. Valves that
are required to be repositioned during an accident to mitigate the
consequences will still be tested on a refueling frequency. The
proposed change only deletes unnecessary or redundant testing
requirements from the TS. Therefore, the proposed change does not
create the possibility of a new or different kind of accident from any
previously analyzed.
(3) The proposed changes do not involve a significant reduction in
a margin of safety.
The proposed changes delete unnecessary or redundant surveillance
requirements within the TS. The deletion of TS 3.2, Table 3-5 Item 6, only deletes testing requirements that are already required to be
conducted by TS 3.3(1)a. The deletion of the requirement to test the
RW backup valves to the containment air coolers in TS 3.6(3) only deletes
an unnecessary surveillance. RW direct cooling of the containment air
coolers is not required to maintain containment pressure below the
design limit of 60 psig. 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

Date of amendment request September 26, 1994.
Description of amendment request: The amendment would remove the
requirement for operability of the Average Power Range Monitors (APRMs) while the plant is in Operational Condition 5. However, the
requirement
for the APRMs to be operable during a shutdown margin demonstration, when the mode switch is in Startup, will remain unchanged.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards
construction, which is presented below:
I. This proposal does not involve a significant increase in the
probability or consequences of an accident previously evaluated.
Not requiring APRMs to be OPERABLE in OPCON 5 will not increase
the probability of inadvertent reactor critically during refueling
operations. Refueling Interlocks, NMS [Neutron Monitoring System]
(SRMs
[Source Range Monitor], IRMs [Intermediate Range Monitor]), and
procedural restrictions provide assurance that inadvertent criticality
does not occur due to the simultaneous withdrawal or removal of two
control rods or due to the inadvertent insertion of a fuel bundle into
a core location with a control blade removed.
The FSAR [Final Safety Analysis Report] Section 15.4.1 discusses
the potential for a control rod withdrawal error during refueling and
start-up operations. The discussion concludes that the withdrawal of
one control rod does not require a safety action because the total
worth of one control rod is not sufficient to cause criticality. The file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (45 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval attempted withdrawal of two control rods, assuming an operator error and a single active failure, would result in a control rod block
initiated by the Refueling Interlocks. The safety-related IRM subsystem, which is required by Technical Specifications to be OPERABLE while in OPCON 5, is designed to generate a rod block or reactor scram
on high neutron flux and is therefore a backup protective system for
the Refueling Interlocks during refueling.
The Safety-related IRM subsystem of the NMS is required by
Technical Specifications to be OPERABLE during OPCON 5 to support the
safety design bases of the NMS and RPS [Reactor Protection System].
The SRM is not a safety-related subsystem but is important to plant safety
and is required by Technical Specifications to be OPERABLE in OPCON 5.
The SRM subsystem provides the plant operator with neutron flux levels from startup conditions to the IRM operating range. The SRMs and IRMs
are designed to respond to local core conditions and would indicate
and respond (control rod block or scram) to an accident condition to
mitigate the transient. Thus, the APRMS are not necessary to be
OPERATOR in OPCON 5. The proposed Technical Specification change will
not alter the current requirements that the APRMs be OPERABLE during
shutdown margin demonstrations in OPCON 5 when the mode switch is in
Startup.
The proposed Technical Specification change would reduce the APRM
operability requirement in OPCON 5 and would not affect the FSAR
evaluation of the inadvertent criticality due to the withdrawal or removal of the highest worth control rod or due to the insertion of
fuel bundles in uncontrolled cells. The FSAR concludes that the
Refueling Interlocks and plant procedures provide assurance that
inadvertent criticality does not occur during refueling.
The consequences of an accident will not be increased by the
proposed Technical Specification change because of the existing lines
of defense which prevent an inadvertent criticality event during
refueling, e.g., administrative restrictions, refueling procedures, licensed plant operators, SRMs, Refueling Interlocks, and IRMs.
Furthermore, should the number of operator IRM or SRM channels be less
than that required by Technical Specifications, the Technical
Specifications require that core alteration activities be suspended
and all insertable control rods be inserted into the core.
Therefore, the proposed changes do not result in an increase in
the file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (46 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval probability or consequences of an accident previously evaluated.
II. This proposal does not create the possibility of a new or
different kind of accident from any accident previously evaluated.
The proposed changes to the Technical Specifications will remove the APRM operability requirement while in OPCON 5 (except for shutdown
margin demonstration testing); however, the SRMs and IRMs will still
be required to be OPERABLE in OPCON 5.
The IRMs are safety-related and are designed to detect and respond
to increases in neutron flux within the local core regions. Any
inadvertent increases in neutron flux during refueling would originate
at a local core location, i.e., rod withdrawal error or fuel bundle
insertion. Technical Specifications require IRM operability and will
generate an RPS scram or control rod block if neutron flux increased to the setpoint. Therefore, removing the APRMs operability requirement in
OPCON 5 would not effect any safety related equipment or equipment
important to safety.
The APRMs provide core power information to the control room
operator and also provide trip signals to the RMCS [Reactor Manual
Control System] and RPS as required. The absence of an APRMs input
signal will not affect these systems during refueling operations.
Removing the APRMs operability in OPCON 5 will not affect the
response of safety-related equipment as previously evaluated in the
FSAR. The proposed changes to the Technical Specifications do not
affect any safety-related equipment or equipment important to safety.
The proposed changes to the Technical Specifications would remove the APRMs operability requirement during refueling operations.
Technical Specifications require IRM operability and will generate an
RPS scram or control rod block if neutron flux increased to the
applicable setpoint.
No new types of accidents would be introduced since the SRMs and
IRMs are available and required to be OPERABLE in OPCON 5. Both SRMs
and IRMs would indicate and provide a control rod block or scram
signal, as appropriate, to an increase in neutron flux to mitigate a
transient event. Furthermore, should the number of OPERABLE IRM or SRM
channels be less than that required by Technical Specifications, the
Technical Specifications require that core alteration activities be
suspended and all insertable control rods be inserted into the core.
Therefore, the proposed Technical Specification changes do not
create the possibility of a new or different kind of accident from any
accident previously evaluated.
III. This change does not involve a significant reduction in a file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (47 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval margin of safety.
For the reasons discussed in items 1 and 2 above and because the
Technical Specification Bases do not discuss or require APRMs operability during OPCON 5, Refueling, the proposed Technical Specification changes do not involve a significant reduction in a
margin of safety.
The NRS 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. Local

Description of amendment request: The amendment consists of five
(5) sections of Technical Specifications changes which reflect the
Improved Standard Technical Specifications (NUREG-1433):
Section 1: Control Rod Block Instrumentation, Section 2: Standby Liquid Control System Operability in Mode 5, Section 3: Scram Discharge Volume Valve Testing, Section 4: Optional Method of Scram Timing, and
Section 5: Definition of Core Alteration.
Basis for proposed no significant hazards consideration determination: 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:
Section 1: Control Rod Block Instrumentation
- 1. The proposed Technical Specifications (TS) changes do not
involve a significant increase in the probability or consequences of
an accident previously evaluated.
file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (48 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval The proposed TS changes can be divided into two general categories, the deletion of the ``S/U requirements, and the change in frequency of the SRM [Source Range Monitor] and IRM [Intermediate Range Monitor]
Calibration and Functional Tests. In each case in which the ``S/U
requirement has been deleted, the normal surveillance frequency
specified for the required Operating Condition remains. The
equipment's associated probability of failure remains unchanged. In the case of
the surveillance frequency changes proposed for the SRMs and IRMs, the
probability of an accident evaluated in the SAR [Safety Analysis
Report] occurring does not increase since there is no credit taken in
the SAR for those Control Rod Block functions with respect to an accident. As such, the proposed changes will not result in an increase in the probability of occurrence of an accident previously evaluated
in the SAR. The proposed TS changes do not alter the method of operation
or performance of the equipment in carrying out associated Control
Rock Block functions. Thus, the consequences of an accident previously
evaluated in the SAR are not increased.
Therefore, the proposed TS changes do not involve an increase in
the probability or consequences of an accident previously evaluated.
- 2. The proposed TS changes do not create the possibility of a new
or different kind of accident from any accident previously evaluated.
The proposed TS changes do not alter the configuration of the plant or the way that the plant is operated. The equipment can perform no other function than it is presently capable of, or cause or permit any
other accident than is now possible. Thus, the possibility of an
accident of a different type than previously evaluated in the SAR
cannot be created.
Therefore, the proposed TS changes do not create the possibility
of a new or different kind of accident from any previously evaluated.
- 3. The proposed TS changes do not involve a significant reduction
in a margin of safety.
Since the proposed TS changes affect only the surveillance
frequency intervals and do not change the plant configuration or
associated instrument setpoints, there is no quantitative or
qualitative reduction in the margin of safety. Thus, the margin of
safety as defined in the bases of any Technical Specification is not file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (49 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval reduced. Therefore, the proposed TS changes do not involve a reduction in a
margin of safety.
Section 2: Standby Liquid Control System Operability in Mode 5
- 1. The proposed Technical Specifications (TS) change does not
involve a significant increase in the probability or consequences of
an accident previously evaluated.
The proposed TS change will remove the SLCS operability
requirement
in OPCON 5. The purpose of the SLCS is to bring the reactor to and
maintain it in a cold shutdown condition from normal power operations
following failure to scram during power operations. Initiation of the
SLCS is not a precursor to any accident. Therefore, inoperability of the SLCS in OPCON 5 cannot increase the probability of an accident previously evaluated.
The proposed TS change does not involve a physical change in any
system's configuration and no new modes of operation are introduced.
The SLCS has not analyzed function OPCON 5. The probability of fuel
failure will not be increased by this change. Shutdown margin, in
conjunction with TS requirements and procedural controls, will assure
that an inadvertent criticality event will not occur during refueling.
In addition, the Reactor Protection System (RPS) and Control Rod
System will provide protection in the unlikely event that an inadvertent
criticality should occur.
Therefore, the proposed TS change does not involve an increase in the probability or consequences of an accident previously evaluated.
- 2. The proposed TS change does not create the possibility of a new
or different kind of accident from any accident previously evaluated.
The proposed TS changes does not involve a physical change in any
system's configuration and no new modes of operation are introduced.
The SLCS's only purpose is to mitigate the consequences of a failure
to scram during power operation. In OPCON 5, the SLCS has no analyzed
function, therefore, the proposed TS change will not create the
possibility of a new or different kind of accident from any previously
evaluated.
- 3. The proposed TS change does not involve a significant reduction
in a margin of safety.
The purpose of the SLCS is to bring the reactor to and maintain it
in a cold shutdown condition from normal power operations following a
failure to scram during power operations. The SLCS is not designed to file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (50 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval terminate an inadvertent criticality during OPCON 5. Shutdown margin, either demonstrated or analytically determined, in conjunction with
Technical Specifications and procedural controls, will assure that an inadvertent criticality event will not occur during refueling operations. In addition, the RPS and Control Rod System, which are
extremely reliable, will provide protection in the unlikely event that
an inadvertent criticality does occur. Therefore, the proposed TS
change does not involve a reduction in a margin of safety.
Section 3: Scram Discharge Volume Valve Testing
- 1. The proposed Technical Specifications (TS) change does not
involve a significant increase in the probability or consequences of
an accident previously evaluated.
The Scram Discharge Volume (SDV) is not an accident initiator.
Deletion of the requirement that the SDV be determined OPERABLE by testing the SDV vent and drain valves when control rods are scram
tested from a normal control and configuration of less than or equal
to 50% rod density at least once per 24 months, as proposed, will have no effect on the probability or consequences of an accident previously
evaluated.
This proposed TS will have a negligible impact on the conditions
experienced by the vent and drain valves as they stroke closed, since
the SDV is initially vented to the atmosphere, and the valves close
before the SDV becomes pressurized, even during a scram at full
reactor power. Reactor pressure and Control Rod Drive (CRD) discharge flow conditions do not influence the SDV vent and drain closure rates, since the SDV is of sufficient volume and initially vented such that peak
pressure prior to the SDV complete isolation will not be substantial.
In addition, lower coolant temperatures expected during testing at
shutdown conditions will also have a negligible impact on the
performance of the test. Although, there could be some variation in
the performance [of] the SDV vent and drain valves to re-open when
performing the test during shutdown conditions, as opposed to
conducting the test during power operation, the ability of the valves
to re-open is demonstrated after each reactor scram during power
operation.
In the event and SDV vent or drain valve failed to open, increasing
SDV level during reactor operation would cause 1) an alarm in the Main file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (51 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval Control Room (MCR), 2) a control rod block, and finally a reactor scram initiated by the Reactor Protection System (RPS) if action is not taken to drain the SDV. Therefore, the ability to shut down the reactor is
not impaired. If a SDV vent or drain valve fails to close, the
redundant valve's closure would provide the required function. If both
valves failed to close, a loss of reactor coolant in the form of water discharged from the CRD system would occur. The amount of water
discharged will be relatively small, and is more of a concern from the
standpoint of contamination to the Secondary Containment rather than a
loss of reactor water inventory. A structural failure of the SDV, which bounds this case of an open SDV vent or drain line, has been previously evaluated in NUREG-0808, ``Generic Safety Evaluation Report Regarding
Integrity of BWR Scram System Piping. In this evaluation, the NRC
concluded that, for a bounding leakage case corresponding to a rupture
of the SDV, the offsite doses would be well within the limits of
10CF100, and that adequate core cooling would be maintained.
Deletion of the requirement that the SDV be determined OPERABLE by
testing the SDV vent and drain valves, as proposed in this TS Change
Request, will have an insignificant effect on the probability of
occurrence of malfunction of any plant equipment. The conditions in
the SDV at the time of vent and drain valve closure are not appreciably
different whether a scram is initiated from power operation or during shutdown conditions. In addition, this proposed TS change eliminates
the potential need for an additional startup and shutdown cycle, along
with the associated challenges to all systems and components, that
would be required to satisfy the current TS requirements in the event
a unit were to trip off-line shortly before a planned outage when the
surveillance was scheduled to be performed. Furthermore, this proposed
TS changes does not affect the testing frequency for the valves.
This proposed TS change will not result in appreciably different
conditions experienced by the valves as they close, and their ability
to re-open is confirmed following each reactor scram from power
conditions. The consequences resulting from a failed closed or failed
open SDV vent or drain line have been evaluated and determined not to
result in offsite doses that would exceed the limits specified in
10CFR100, or jeopardize adequate reactor core cooling capability.
Therefore, the consequences of a malfunction of equipment important to file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (52 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval safety previously evaluated is not increased.
Therefore, the proposed TS change does not involve an increase in
the probability or consequences of an accident previously evaluated.
- 2. The proposed TS change does not create the possibility of a new or different kind of accident from any accident previously evaluated.
The SDV is not an accident initiator. Deletion of the requirement
that the SDV be determined OPERABLE by testing the SDV vent and drain
valves from a configuration of less than or equal to 50% rod density, as proposed, will not create the possibility of a different type [of]
accident than any previously evaluated.
No plant equipment is added or deleted as a result of this
proposed change. Since the initial conditions of pressure, temperature, and CRD
system discharge flowrate have no appreciable effect on the SDV vent and drain valve performance, no different type of malfunction of any equipment important to safety is created.
Therefore, the proposed TS change does not create the possibility
of a new different kind of accident from any previously evaluated.
- 3. The proposed TS change does not involve a significant reduction
in a margin of safety.
Since the initial test conditions of pressure, temperature, and
CRD discharge flowrate will have no appreciable effect on the SDV vent and
drain valve performance, conducting the surveillance test during
shutdown conditions, as specified in this proposed TS change, will not
affect the validity of the surveillance results with respect to the
operability of the SDV to perform its intended safety function.
Furthermore, every reactor scram is a serious plant transient and a
potential challenge to safety-related systems and equipment. The
potential decrease in future scrams which could result from this
proposed TS change will represent an improvement in overall safety.
Therefore, the proposed TS change does not involve a reduction in
a margin of safety.
Section 4: Optional Method of Scram Timing
- 1. The proposed Technical Specification (TS) changes involves a
significant increase in the probability or consequences of an accident
previously evaluated.
Scram testing control rods at zero reactor coolant pressure will
not increase the probability of any control rod related transient or
accident discussed in the UFSAR [Updated Final Safety Analysis
Report].
UFSAR Sections 15.4.1.1 and 15.4.1.2 discuss the consequences of file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (53 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval inadvertent reactivity insertion errors due to the withdrawal of one or more control rods. The probability of one of these events occurring is a function of operator error and equipment malfunction and is not related to scram insertion times.
An inadvertent reactivity insertion error is prevented by existing
system hardware interlocks and procedural controls that are not
affected by scram time testing, e.g., core design, control and design, one-rod-out interlocks, refueling interlocks, control rod sequence
designations, and neutron monitoring systems.
USFAR Section 15.4.9 discusses the control rod drop accident (CRDA). The CRDA assumes that a control rod suddenly drops out of the
core due to equipment malfunction. The probability of occurrence of
this accident is based on an equipment malfunction and is not affected by scram testing.
Engineering analysis and control rod scram test data demonstrate
that a control rod drive that will meet the 2.0 second, scram
insertion
time, test criteria at zero reactor coolant pressure will also meet
all scram insertion criteria during reactor startup and up to 40% rated
thermal power.
The 2.0 second criterion was chosen to conservatively envelop
scram time criteria and reactivity insertion criteria during reactor startup
and up to 40% rated power conditions. Therefore, scram testing
affected control rods at zero reactor pressure will not increase the
consequences of an accident previously evaluated.
UFSAR Sections 15.4.1.1 and 15.4.1.2 evaluate reactivity insertion
transients at low power conditions due to inadvertent control rod
withdrawal errors. The UFSAR concludes that rod withdrawal errors at
low power are adequately precluded by refueling interlocks, rod worth
minimizer, operating procedures, core design, and control rod hardware
design. However, should operator errors followed by equipment
malfunctions result in an inadvertent criticality event, the IRMs
would provide the necessary rod blocks or reactor scram to preclude the
operational transient. Scram insertion time limits for the continuous
rod withdrawal error during startup is 5.0 seconds. This scram time
criterion will be met by a control rod that scrams within 2.0 seconds
at zero reactor pressure. The 2.0 second scram criterion was
established to ensure that affected control rods will meet scram file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (54 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval requirements from zero reactor pressure up to 40% core thermal power.
Also, during low power operation (UFSAR Subsection 15.4.1.2) the
rod worth minimizer (RWM) prevents the operator from selecting and withdrawing an out-of-sequence control rod. During reactor operation in the power range (UFSAR subsection 15.4.2) the rod block monitor (RBM)
prevents a rod withdrawal error by inhibiting inadvertent control rod
withdrawal. The RWM and RBM do not rely on a scram function to mitigation the consequences of a rod withdrawal error, and therefore
the consequences of an accident evaluated in the UFSAR will not be
affected by the proposed changes to the Technical Specifications.
The consequences of a control rod drop accident (UFSAR Section
15.4.9) would not be affected by scram testing a control rod at zero
reactor pressure. The design basis accident of the rod drop accident assumes that control rods scram within 5.0 seconds. This 5.0 second scram test requirement will be met by control rods that meet the 2.0
second criterion at zero reactor pressure.
Therefore, the proposed TS changes do not involve an increase in
he probability or consequences of an accident previously evaluated.
- 2. The proposed TS change does not create the possibility of a new
or different kind of accident from any accident previously evaluated.
The changes to the Technical Specifications will allow control
rods to be scram tested at zero reactor pressure and then again at rated
reactor pressure prior to achieving 40% rated reactor power.
No new types of accidents will be introduced since control rods that meet the
2.0 second
scram criterion at zero reactor pressure will also meet all
scram test criteria during reactor startup and at rated reactor
pressure.
Therefore, the proposed TS changes do not create the possibility
of a new or different kind of accident from any previously evaluated.
- 3. The proposed TS changes do not involve a significant reduction
in a margin of safety.
The basis for shutdown margin (TS Bases 3/4.1.1) states that the
reactor shall be made subcritical by all certain margin in all
operating and shutdown conditions. The proposed changes to the
Technical Specifications will not affect the shutdown margin
requirements. Adequate shutdown margin is assured by core design, the
one-rod-out interlock, and administrative controls.
The basis for the control rod insertion times (TS Bases 3/4.1.3)
states that the scram times are to be consistent with those used in file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (55 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval the transient and accident analysis. The proposed Technical Specifications
changes will add an additional scram test verification for affected control rods at zero reactor pressure. The zero reactor pressure scram limit (2.0 seconds) was designed to ensure that the scram times
assumed in the transient analysis will remain bounding from zero reactor
pressure up to 40% rated core thermal power.
The basis for the control rod drop accident (TS Bases 3/4.1.3)
states that the potential effects of a CRDA are limited. The proposed
Technical Specifications changes will not effect the control rod drop
results as the changes do not affect the reactivity of the rod or the
rod drop velocity. The CRDA analysis is based on a 5.0 second scram
insertion time criterion. The 2.0 second time criterion was established to ensure that the 5.0 second scram time criterion was valid from zero
reactor pressure to 950 psig reactor pressure.
The basis for MCPR limits (TS Bases 3/4.1.3 and 2.3) states the
CRD system must bring the reactor subsubcritical at a rate fast enough to
prevent MCPR from becoming less than the fuel cladding safety limit
during the limiting power transient analyzed in the UFSAR. The
proposed changes to the Technical Specifications will not affect the scram
insertion rates that are used as input to the transient analysis. The
zero reactor pressure scram limit of 2.0 seconds was developed to
ensure that the control rods would meet their design scram insertion times from zero reactor pressure up to 40% rated power.
The proposed changes to the Technical Specifications will not
increase the probability of inadvertent criticality because the
changes do not affect the reactivity worth of control rods.
Therefore, the proposed TS changes do not involve a reduction in a
margin of safety.
Section 5: Definition of Core Alteration
- 1. The proposed TS change does not involve a significant increase
in the probability or consequences of an accident previously evaluated.
The proposed definition change removes the requirement to have a
SRO or LSRO supervise control rod withdrawal in an off-loaded cell (i.e. no fuel assemblies). The evaluated accident potentially affected
by this change is a control rod movement error during refueling
resulting in inadvertent criticality. The supervision by a SRO or LSRO
does not solely preclude inadvertent criticality and was not relied file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (56 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval upon in the accident analysis contained in Section 15.4 of the LGS Updated Final Safety Analysis Report (UFSAR). The LGS reactor core is
designed to have adequate shutdown margin with the highest-reactivity-worth control rod withdrawn. The withdrawal of a second rod with fuel assemblies loaded in the associated cell is prevented by a combination
of the refueling, one-rod-out interlock, and the Limiting Conditions
for Operation (LCO) requirement of TS 3.9.10.2. The LCO requirements
ensure adequate shutdown margin is present prior to control rod withdrawal. This is accomplished by testing during startup following a
refueling outage or by analytical calculations during refueling. The
refueling interlock will provide a rod block upon an attempt to
withdraw a second control rod and is required to be operable in
accordance with TS 3.9.10.2 except for rods which have no fuel assemblies in the associated cell. The removal of the fuel assemblies from a cell eliminates the need for the reactivity control function of the associated rod. The physical removal of a control blade from the
core by means of the refueling floor, first requires the removal of
the four associated fuel assemblies in the cell. This design inherently
prevents inadvertent criticality. Finally, this change is consistent
with NUREG-1433 ``Standard Technical Specifications. Since current
analysis permits the withdrawal of a control rod blade, provided the
associated cell is unloaded, and refueling mode interlocks, administrative TS requirements and the physical design of the control
blade and fuel cell, which preclude inadvertent criticality, will
remain unchanged, this proposed change to the TS definition of CORE
ALTERATION will not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2. The proposed TS change does not create the possibility of a new
or different kind of accident from any accident previously evaluated.
The LGS UFSAR currently permits control rod withdrawal and or
removal, provided there are no fuel assemblies in the associated fuel
cell. The definition change removes the requirement to have a SRO or
LSRO supervise rod withdrawal in an off-loaded cell. The change
potentially [a]ffects a control rod movement error during refueling
resulting in inadvertent criticality which has been previously
evaluated. In addition, the proposed change will make no physical
changes to equipment or remove administrative controls which solely
preclude inadvertent criticality. Therefore, this change will not
create the possibility of a new or different kind of accident from any
accident previously evaluated.
- 3. The proposed TS change does not involve a significant reduction
in a margin of safety.
file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (57 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval The LGS TS bases address reactivity concerns, radiological releases, control rods, and monitoring of the facility related to this
change. With the four fuel assemblies removed from a cell, the control rod/blade in the associated cell has no reactivity function. The reactivity issues addressed by TS are therefore unaffected. The rod/
blade coupling integrity is maintained by the requirement to perform a
coupling check following maintenance. Section 15.4 of the UFSAR states
that there are no radiological releases in association with a rod withdrawal error during refueling. This conclusion is maintained by
the administrative requirements of TS 3.9.10.2, the refueling interlocks
for one-rod-out, and the physical design of the blade and cell.
- Lastly, the TS requirements for Emergency Core Cooling, Plant System, Containment, and Electrical Power Distribution System, which provide the systems necessary to mitigate the effects of a radiological
release during control rod movement in an unloaded cell were reviewed and were
found not to be adversely [a]ffected by the proposed change.
Therefore, this change will not involve a significant reduction in a margin of
safety.

provided its analysis of the issue of no significant hazards
consideration, which is presented below:
Section 1: Relocation of Turbine Overspeed Protection System
Requirements
- 1. The proposed TS change does not involve a significant increase
in the probability or consequences of an accident previously evaluated.
The proposed change relocates requirements from the TS, to
licensee controlled documents. The licensee controlled documents containing the
relocated requirements will be maintained using the provisions of 10 CFR 50.59 and are subject to the change control process in the
Administrative Controls Section 6.0 of the TS. Since changes to
licensee controlled documents will be evaluated per 10 CFR 50.59, no increase (significant or insignificant) in the probability or
consequences of an accident previously evaluated will be allowed.
Therefore, this change will not involve a significant increase in the
probability or consequences of an accident previously evaluated.
- 2. The proposed TS change does not create the possibility of a new
or different kind of accident previously evaluated.
This change relocates requirements to licensee controlled
documents. This change will not alter the plant configuration (no new or different type of equipment will be installed) or make changes in
methods governing normal plant operation. This change will not impose
different requirements and adequate control of information will be
maintained. This change will not alter assumptions made in the safety
analysis and licensing basis. Therefore, this change will not create file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (59 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval the possibility of a new or different kind of accident from any accident previously evaluated.
- 3. The proposed TS change does not involve a significant reduction in a margin of safety.
This change relocates requirements from the TS to licensee
controlled documents. This change will not reduce a margin of safety
since it has no impact on any safety analysis assumptions. In
addition, the requirements to be transferred from the TS to licensee controlled
documents are the same as the existing Technical Specifications. Since
any future changes to these licensee controlled documents will be
evaluated per the requirements of 10 CFR 50.59, no reduction (significant or insignificant) in [a] margin of safety will be
allowed. Therefore, this change will not involve a significant reduction in a margin of safety.
The existing requirements for NRC review and approval of
revisions, in accordance with 10 CFR 50.59, to these details and requirements
proposed for relocation, does not have a specific margin of safety
upon which to evaluate. However, since the proposed change is inconsistent
with the BWR [boiling-water reactor] Improved Standard Technical
Specifications (NUREG-1433 approved by the NRC Staff) and the change
controls for proposed relocated details and requirements provide an
equivalent level of regulatory authority, revising the TS to reflect
the approved level of detail and requirements ensures no reduction to the margin of safety.

Section 3: Feedwater/Main Turbine Trip System Actuation
Instrumentation
Requirements
- 1. The proposed TS change does not involve a significant increase
in the probability or consequences of an accident previously evaluated.
For the proposed TS change, in the event of a Reactor Vessel Water
Level--High Level 8 transient, operator action per existing plant
procedures would terminate the event and prevent damage to the Main/
file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (61 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval RFP [reactor feed pump] Turbine due to water carry over. The Main/RFP
Turbine do not serve a safety function, also at <25% [Rated Thermal Power] RTP a level 8 transient event will not cause a reactor scram.
An analysis of information in the bases for APLHGR [average planar linear
heat generation rate] and MCPR [minimum critical power ratio] has
shown that a sufficient margin to core safety limit exist, so fuel integrity
levels are not violated. Therefore, the proposed TS change does not
involve an increase in the probability or consequences of an accident
previously evaluated.
- 2. The proposed TS change does not create the possibility of a new
or different kind of accident from any accident previously evaluated.
Should the feedwater/main turbine trip system, Reactor Vessel Water Level-High Level 8, not actuate in OPCON 1 at <25% RTP, operator
action per existing plant startup procedures would protect the Main/RFP
turbines. If operator action is not performed, damage to Balance of
Plant, non-safety related equipment could occur. High Reactor Vessel
Water Level is not a concern for reactor core safety at <25% RTP.
Therefore, the proposed TS change does not create the possibility of a
new or different kind of accident from any accident previously
evaluated.
- 3. The proposed TS change does not involve a significant reduction
in a margin of safety.
The proposed TS change, which revises the feedwater/main turbine
trip system actuation instrumentation, Reactor Vessel Water Level-High
Level 8, operability requirements, does not affect the TS bases. The
trips are designed to protect Balance of Plant Equipment at all Rate
Power Levels. The Reactor Vessel Water Level-High Level 8 trips also
protects fuel integrity at >25% RTP. Therefore, the proposed TS change
to the operability requirements for the feedwater/main turbine trip
system actuation instrumentation does not involve a reduction in a
margin of safety.
Section 4: Permit Operability of Low Pressure Coolant Injection While
Aligned to Shutdown Cooling
- 1. The proposed Technical Specifications change does not involve a
significant increase in the probability or consequences of an accident
previously evaluated.
The LPCI [low pressure coolant injection] mode of RHR is an
accident mitigator, not an initiator. Currently, the LPCI mode of RHR file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (62 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval is an automatic Emergency Core Cooling System (ECCS) function during OPCONs 4 and 5. However, shutdown cooling has been an accident
initiator in many industry events. Reliance on this loop of RHR for LPCI does not increase the probability of an accident in shutdown cooling, but the alignment for LPCI will, in itself, terminate the
draindown event by exiting the shutdown cooling mode. This proposed
change will permit the operability of one LPCI subsystem while the
components of that subsystem are aligned and operating in the Shutdown Cooling mode of RHR, provided all other components of that subsystem
are operable and can be manually realigned from the Main Control Room, if required. The required number of operable Emergency Core Cooling
Systems (ECCS) remains unchanged, thus maintaining the TS required
subsystem redundancy (TS Section 3.5.2 requires two operable ECCS
subsystems with exception for Reactor level). With this change, the required number of LPCI subsystems are capable of performing their function of limiting and/or mitigating the consequences of an
- accident, by allowing the manual alignment of one LPCI subsystem, during OPCONs
4 and 5. This allowance is justified since the change only applies to
OPCONs 4 and 5, when reactor temperature, and associated heat loads
are sufficiently low to provide the operator sufficient time to perform
the manual realignment, from the Main Control Room, of the RHR pump
suction valves and restart of the pump following LPCI injection conditions.
Similar allowances for LPCI are currently permitted during OPCON 3, since the decay heat loads are significantly reduced compared to OPCON
1, which is the mode of operation under which ECCS capability is
analyzed (Section 6.3 of the LGS [Limerick Generating Station] Updated
Final Safety Analysis Report (UFSAR)). The change will not increase
the probability of occurrence or consequences of a malfunction of
equipment
since there will be no physical changes made to plant equipment nor
the method of their operation that would result in an unanalyzed
condition.
PECO Energy [Philadelphia Electric Company] evaluated the need for
manual realignment of the pump minimum flow path since operating in
Shutdown Cooling typically results in the isolation of the pump
minimum file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (63 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval flow path to prevent inadvertent draining of the reactor vessel. The associated pump is still operable since this change is limited to
OPCONs 4 and 5, when reactor pressure is sufficiently low to allow immediate injection to the reactor vessel without a minimum flow path.
In situations, while in OPCON 4, where reactor pressure may not be
sufficiently low to allow injection, the RHR system will not be
aligned for Shutdown Cooling, since the reactor vessel pressure will be greater than the RHR ``cut-in permissive pressure. In addition, Administrative Controls are currently in place to realign RHR to the
LPCI mode for planned pressure increases. Finally, this change is
consistent with NUREG-1433 ``Standard Technical Specifications.
Therefore, these changes will not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2. The proposed TS change does not create the possibility of a new
or different kind of accident from any accident previously evaluated.
The LPCI mode of RHR is an accident mitigator, not an initiator.
This change will not reduce the number of required ECCS during OPCONs
4 and 5. This change will permit the operability of one LPCI subsystem
while the components of that subsystem are aligned and operating in
the Shutdown Cooling mode of RHR. The change does not alter current
methods of plant operation nor does the change make a physical change to plant equipment resulting in an unanalyzed malfunction of equipment.
Therefore, this change will not create the possibility of a new or
different kind of accident from any accident previously evaluated.
- 3. The proposed TS change does not involve a significant reduction
in a margin of safety.
The basis of TS Section 3.5.2 is to ensure sufficient ECCS
capacity to maintain core cooling in OPCONs 4 and 5. This proposed change does
not affect the required number of ECCS during OPCONs 4 and 5;
therefore, adequate capability through subsystem redundancy is
maintained. The amount of time required to obtain rated LPCI
conditions
is increased due to the manual realignment, from the Main Control
injection conditions. This change is in conformance with the current file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (64 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval TS bases, since the operator has sufficient time to perform the manual
realignment, during OPCONs 4 and 5, ensuring sufficient ECCS capability to maintain core coverage. In addition, NUREG-1433 BASES states, in
part, ``One LPCI subsystem may be aligned for decay heat removal and
considered OPERABLE for the ECCS function, if it can be manually
realigned (remote or local) to the LPCI mode and is not otherwise inoperable. Because of low pressure and low temperature conditions in
MODES 4 and 5, sufficient time will be available to manually align and
initiate LPCI subsystem operation to provide core cooling prior to
postulated fuel uncover. Therefore, this change will not involve a
significant reduction in a margin of safety.
Section 5: Remove Temperature Requirement for Operational Condition 5
- 1. The proposed Technical Specifications (TS) change does not involve a significant increase in the probability or consequences of
an accident previously evaluated.
The proposed TS change does not involve a physical change in the
configuration of any systems important to safety. The elimination of a
temperature requirement from the definition of OPCON 5 was reviewed
for potential effect on reactor coolant system materials and for potential
effect on reactivity. This TS change does not result in system
temperature and pressure change or reactivity changes not previously
analyzed. The reactor pressure vessel will still be restricted to the
temperature and pressure limits of TS Section 3/4.4.6 which includes heatup/cooldown rates and minimum boltup limits. The reactor pressure
vessel temperature and pressure limits will still ensure proper
protection of the reactor coolant system materials. Therefore, this TS
change does not increase the probability or consequences of an
accident previously evaluated.
- 2. The proposed TS change does not create the possibility of a new
or different kind of accident from any accident previously evaluated.
The proposed TS change does not involve any physical change in
plant configuration, and reactor coolant system temperature and
pressure are still restricted per TS Selection 3/4.4.6. The decrease
in moderator density corresponding to the potential change in temperature (i.e., above 140 deg.F and below 200 deg.F) would have a negligible, however conservative effect on shutdown margin. Therefore, this TS
change does not create the possibility of a new or different kind of file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (65 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval accident from any accident previously evaluated.
- 3. The proposed TS change does not involve a significant reduction
in a margin of safety.
This proposed TS change does not change the reactor coolant system material restrictions as defined in TS Section 3/4.4.6. Therefore, the
reactor pressure vessel will still be maintained under the current
temperature and pressure restrictions as well as the current boltup
limits. The decrease in moderator density corresponding to the potential
temperature change from 140 deg.F to 200 deg.F is insignificant and
would afford approximately the same moderator effect. Therefore, shutdown margin could only be improved (although marginally) at these
evaluated temperatures. The actual coolant temperature will be
administratively controlled to provide for personnel safety.
Therefore, this change will not involve a reduction in a margin of safety.
Section 6: Reduce Frequency of Alternate Decay Heat Demonstration
- 1. The proposed TS change does not involve a significant increase
in the probability or consequences of an accident previously evaluated.
The proposed TS change does not involve any physical changes to
plant systems or equipment. This proposed TS change will allow the use
of either an ``analytical approach (i.e., calculation) or
``demonstration to ensure the operability of an alternate decay heat
removal method. This proposed TS change does not involve any physical
changes to plant systems or components, nor does it affect the
capability, availability, or operability of any decay heat removal
systems/methods (e.g., Shutdown Cooling). The Shutdown Cooling mode of operation of the Residual Heat Removal (RHR) system, and Residual Heat
Removal Service Water (RHRSW) system, are not impacted by this
proposed TS change, and will continue to function as designed to remove decay
heat loads from the reactor primary coolant system. The RHRSW system
and various modes of operation of the RHR system, e.g., Low Pressure
Coolant Injection (LPCI) are not accident initiators, since these
systems function to mitigate the consequences of an accident. This
proposed TS change is consistent with the criteria delineated in the
Improved Standard TS (i.e., NUREG-1433, ``Standard Technical
Specifications, General Electric Plants, BWR/4, dated September 28, 1992).
Therefore, the proposed TS change does not involve an increase in
the probability or consequences of an accident previously evaluated.
- 2. The proposed TS change does not create the possibility of a new
or different kind of accident from any accident previously evaluated.
file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (66 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval This proposed TS change does not involve any physical changes to plant systems or equipment. The proposed TS change will allow the use
of a ``calculation or ``demonstration as the means for determining the operability of an alternate decay heat removal method. The proposed TS change does not involve any physical changes to plant systems or
equipment. This proposed TS change will not affect the operation of
the Shutdown Cooling mode of the RHR system. This mode of operation will
continue to function as designed to remove decay heat loads from the
reactor primary coolant system. This proposed TS change will not
impact the operation of the other modes of operation of the RHR system (e.g.,
LPCI), nor will it affect the operation of the RHRSW system. These systems will continue to function as designed, which is to mitigate the consequences of an accident. This proposed TS change will not
introduce
the potential for equipment malfunctions or failures. This proposed TS
change is consistent with the criteria delineated in the Improved
Standard TS (i.e., NUREG-1433).
Therefore, the proposed TS change does not create the possibility
of a new or different kind of accident from any previously evaluated.
- 3. The proposed TS change does not involve a significant reduction
in a margin of safety.
The proposed change to the TS does not involve any physical
changes to plant systems or equipment. This proposed TS change does not make
any physical modifications to plant systems or equipment, and is
consistent with the criteria delineated in the Improved Standard TS (i.e., NUREG-1433). The proposed TS change will not impact any mode of
operation of the RHR system or the RHRSW system.
This proposed TS change involves revising TS ACTION statements, and associated supporting Bases sections, to allow for the use of a
``calculation or ``demonstration to ensure the operability of an
alternate decay heat removal method. The bases for the TS sections
affected by this proposed change indicate that sufficient heat removal
capability, system redundancy, and coolant circulation will be
available to facilitate decay heat removal and mixing to assure
accurate temperature indication.
This proposed TS change does not affect the function or
availability of any decay heat removal system or method.

times for some of the instruments subject to requirements of the Technical
Specifications (TSs). These proposed changes are based upon NRC-
approved Licensing Topical Reports prepared under the direction of the Boiling Water Reactors Owners Group and intended to enhance plant
safety by reducing the potential for test related scrams, excessive
test cycles on equipment, and operator errors. The proposed amendment
would also: (1) Remove the Average Power Range Monitor (APRM)
downscale
scram function from the TSs, remove instrument response time values
from the TSs in accordance with Generic Letter 93-08, and incorporate
various editorial changes and clarifications into the TSs. The
proposed amendment involves reactor protection system, primary containment
isolation, emergency core cooling, control rod block, and anticipated
transient without scram recirculation pump trip instrumentation.
Basis for proposed no significant hazards consideration
determination: 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:
file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (68 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval Operation of the FitzPatrick plant in accordance with the proposed Amendment would not involve a significant hazards consideration as
defined in 10 CFR 50.92, since it would not:
- 1. involve a significant increase in the probability or consequences of an accident previously evaluated because:
- a. Incorporate STI [Surveillance Test Interval] and AOT [Allowable Out-Of-Service Time] Improvement--Category 1 The proposed changes are limited to an extension of the surveillance testing intervals and allowable out-of-service times of
plant instrumentation. The changes do not introduce any new modes of
plant operation, make any physical changes, or alter any operational
setpoints. Therefore, the changes do not degrade the performance of any safety system assumed to function in the accident analysis.
Consequently, there is no effect on the probability of occurrence of
an accident.
Regarding the consequences of an accident, the GE [General
Electric Company] Licensing Topical Reports (References 1 through 7) concluded
that the proposed extensions in the STI and AOT for the safety system
instrumentation results in an insignificant change in the core damage
frequency. The extension of the STI/AOTs results in a slight increase
in the unavailability of the safety functions. However, this effect is
offset by a reduction in the probability of inadvertent plant trips due to reduced testing. The overall effect on the probability of an
accident is negligible. While the effects of reducing unnecessary
cycles on safety system instrumentation is not quantifiable, the
effect will be to further reduce the core damage frequency. The NRC concurred
in their SERs [Safety Evaluation Reports] (References 8 through 15)
with these conclusions. Consequently, there is not a significant
increase in the consequences of an accident.
- b. Relocation of the Instrument Response Time Limits--Category 2
The change involves the use of an alternate regulatory process for controlling the instrument response time limits. The change does not
introduce any new modes of plant operation, make any physical changes, alter any operational setpoints, or change the surveillance file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (69 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval requirements.
- c. Delete APRM Downscale Scram--Category 3
The design basis accident applicable to the startup power region is the Control Rod Drop Accident (CRDA). The FSAR [Final Safety Analysis
Report] does not credit the APRM downscale scram in the termination of this accident. Accident mitigation is provided by the APRM fixed high
neutron flux scram. Therefore, elimination of this scram functions has
no adverse affect on previously evaluated accidents.
- d. Miscellaneous Changes--Category 4 The changes do not introduce any new modes of plant operation, make any physical changes, or alter any operational setpoints. The changes
involve enhancements that clarify the Technical Specification
requirements.
- 2. Create the possibility of a new or different kind of accident
from those previously evaluated because:
The proposed changes do not introduce any new accident initiators or failure mechanisms since the changes do not introduce any new modes
of plant operation, make any physical changes, or alter any operational
setpoints. The changes reduce the probability of accidents initiated
by test-induced plant trips.
- b. Relocation of the Response Time Limits--Category 2
The change involves the use of an alternate process for controlling
the instrument response time limits. The change does not introduce any
accident initiators since it does not involve any new modes of plant
operation, make any physical changes, alter any operational setpoints, or change the surveillance requirements.
- c. Delete APRM Downscale Scram--Category 3 file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (70 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval Scram functions are intended to shutdown the reactor following transients or accidents and their removal does not introduce an
accident initiator. The limiting accident evaluated in the FSAR for the startup power region is the control rod drop accident. This accident
is assumed to occur irrespective of the scram functions provided to
terminate this accident.
- d. Miscellaneous Changes--Category 4
The changes do not introduce any new accident initiators or failure mechanisms since the changes do not alter the physical characteristics of any plant system or component. The changes involve enhancements that clarify the Technical Specification requirements.
- 3. Involve a significant reduction in the margin of safety because:
The proposed changes do not alter the manner in which safety limits, limiting safety system settings, or limiting conditions for
operation are determined. The affected instrumentation setpoints
already account for the effects of drift and include sufficient
allowance for an extension in the STIs. The evaluations presented in
the referenced Licensing Topical Reports concluded that the overall
effect of the proposed changes provides a net increase in plant safety.
The improvement is achieved by reducing the potential for: (a) Test
related plant scrams (reduced challenges to plant shutdown systems and
improved plant availability); (b) excessive test cycles on equipment (reduced wear-out potential); (c) operator errors (AOT provides
reasonable time for making repairs and tests); (d) scrams that occur
when inoperable channels are tripped because insufficient repair time
exists; and (e) diversion of plant personnel and resources on
unnecessary testing (potential safety and operational improvement).
- b. Relocation of the Response Time Limits--Category 2
The change involves the use of an alternate regulatory process for controlling the instrument response time limits. The change does not
introduce any new modes of plant operation, make any physical changes, file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (71 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval alter any operational setpoints, or change the surveillance requirements.
- c. Delete APRM Downscale Scram--Category 3 The only scram function that the UFSAR [Updated Final Safety Analysis Report] takes credit for in the mitigation of the limiting
accident (control rod drop accident) is the APRM 15% power fixed high neutron flux scram. This scram function, as well as the IRM
[Intermediate Range Monitor] high flux scram function in the startup
mode which could also terminate this accident, are not affected by
this change. Only the APRM downscale scram, for which the UFSAR takes no credit in the termination of any analyzed event, is eliminated by this change. The APRM downscale control rod block is not affected by this change. Elimination of the APRM downscale scram will avoid the need to
operate the plant in a ``half scram condition for certain IRM/APRM
channel bypass combinations, therefore eliminating the potential for
an inadvertent plant transient. For these reasons, the change does not
involve a significant reduction in the safety margin.
- d. Miscellaneous Changes--Category 4
The changes assure compliance with the Technical Specifications by improving its clarity and accuracy. For these reasons the changes will
improve the plant's margin of safety.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Date of amendment request: October 7, 1994.
Description of amendment request: The proposed amendment would revise Technical Specification (TS) 4.6.E.4 to establish that the manual cycling of reactor coolant system (RCS) safety/relief valves (SRVs) during plant startups is to be accomplished within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />
after steam pressure and flow are adequate to perform the testing. TS 4.6.E.4 currently requires this testing to be performed within 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br /> of continuous power operation at a reactor steam dome pressure of at
least 940 psig. This change was proposed to minimize the potential for
undesirable pressure transients in the RCS. The amendment would also
make several editorial changes to clarify the intent of TS's involving
SRV valve testing and performance requirements.
Basis for proposed no significant hazards consideration determination: 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:
Operation of the James A. FitzPatrick Nuclear Power Plant in
accordance with the proposed amendment would not involve a significant
hazards consideration as defined in 10 CFR 50.92, since it would not:
- 1. Involve a significant increase in the probability or
consequences of an accident previously evaluated because the proposed
changes do not change the test method or conditions under which valve
testing may be performed and there is no affect on assumptions used
for previously analyzed accidents. The original operating license for FitzPatrick did not specify any time limit for completing manual
testing of the safety/relief valves.
- 2. Create the possibility of a new or different kind of accident
from those previously evaluated because the proposed amendment does
not involve any modification of plant equipment or changes in plant
operating conditions.
- 3. Involve a significant reduction in the margin of safety because
the proposed amendment makes no changes to the operability of
performance requirements for the safety/relief valves including the
[Automatic Depressurization System] function. Valve lift setpoints and
the minimum number of operable valves required are not affected.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (73 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval amendment request involves no significant hazards consideration.

Date of amendment request: September 9, 1994.
Description of amendment request: The proposed amendment modifies
the visual inspection for snubbers in the Technical Specifications and
is consistent with the guidance provided in Generic Letter 90-09.
Basis for proposed no significant hazards consideration
determination: 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. Will not involve a significant increase in the probability or
consequences of an accident previously evaluated.
The proposed changes involve no hardware changes, no changes to
the operation of snubbers, and does not change the ability of the snubbers to perform their intended functions. Visual inspection of snubbers is
a separate process that complements the functional testing program. The
NRC has concluded that functional testing of snubbers provides a 95
percent confidence level and 90 to 100 percent of the snubbers will
operate within the specified acceptance limits. Any change in the
visual inspection frequency will not have any significant impact on
the operability of the snubbers.
- 2. Will not create the possibility of a new or different kind of
accident from any previously evaluated.
The proposed changes will not result in an unanalyzed condition.
Replacing the current method of determining visual surveillance
intervals with a new method approved by the NRC in Generic Letter 90-
09 file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (74 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval will not change the level of confidence in snubber operability. A new procedure for determining visual inspection frequencies will not
result in an unreviewed failure mechanism.
- 3. Will not involve a significant reduction in a margin of safety.
The proposed changes incorporate the alternate Technical
Specification requirements for visual inspection of snubbers
identified in Generic Letter 90-09. The alternate visual inspection criteria
consider the size of the category of snubbers when evaluating
inspection intervals due to failure rates. Since the functional
testing requirements remain unchanged and do not reduce the operability
confidence levels, there is no resultant change in any margins 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.

Description of amendment request: The proposed amendment modifies
the Technical Specifications for auxiliary feedwater to reduce the
secondary side steam pressure required for testing the steam turbine
driven auxiliary feedwater pump (AFW). The proposed amendment also
clarifies the time required to perform the steam turbine driven
auxiliary feedwater pump surveillance test when entering Mode 3.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the licensee has
provided its analysis of the issue of no significant hazards file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (75 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval consideration, which is presented below:
- 1. Involve a significant increase in the probability or
consequences of an accident previously analyzed.
The proposed change to the minimum required test pressure for the steam turbine driven AFW pump does not affect the operation of the
pump during conditions when it is required to performed its safety
function.
The clarification that the secondary side steam pressure is steam
generator pressure is editorial. Reduced Tavg and increased steam
generator tube plugging will affect the normal operating secondary
side steam pressure.
However, the zero load secondary side steam pressure is not affected, therefore, the conditions in which the steam turbine driven AFW pump will be required to perform its safety function are not
changed.
Providing a specific time frame in which to perform the
surveillance test after attaining the required steam pressure ensures
that the test will be performed in a timely manner. The time frame
specified is consistent with NUREG-1431, Standard Technical
Specifications--Westinghouse Plants.
Therefore, the proposed changes do not involve a significant
increase in the probability or consequences of an accident previously
evaluated.
- 2. Create the possibility of a new or different kind of accident.
The proposed changes do not change system configurations, plant equipment, or analysis. Therefore, the proposed changes will not
increase the possibility of a new or different kind of accident from
any accident previously identified.
- 3. Involve a significant reduction in a margin of safety.
The proposed change to the minimum required steam pressure will
not affect the heat removal capability of the AFW System. Therefore, the
value assumed in the safety analysis is not changed. The change to the
specification 4.0.4 exemption to provide a specific time period does
not affect any margins of safety. Therefore, these changes do not
involve a significant reduction in any 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.

Description of amendment request: These proposed changes would adopt the Westinghouse Standard Technical Specifications (NUREG-1431)
Channel Functional Test surveillance frequency for the Manual Reactor Trip Switches and for the Reactor Trip Breakers (RTB) and relocate RTB
maintenance requirements from the Technical Specifications to the
Salem, Units 1 and 2, Updated Final Safety Analysis Report.
Basis for proposed no significant hazards consideration
determination: 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 not involve a significant increase in the probability or
consequence of an accident previously evaluated.
The proposed changes do not affect accident conditions or
assumptions. They change the existing surveillance test and their frequencies to make them consistent with industry standards, and
relocate maintenance requirements to the UFSAR [Updated Final Safety
Analysis Report].
The changes, for the Manual Reactor Trip Switch and Reactor Trip
Breaker (RTB) CHANNEL FUNCTIONAL TEST frequency, incorporate the
established Westinghouse STS surveillance frequencies. These
surveillance frequencies have received previous NRC review and generic
approval via the issuance of NUREG-1431. The Westinghouse STS does not
require Channel Functional Test for the Manual Reactor Trip Switches
or the RTB prior to each reactor startup.
The addition of the RTB shunt trip feature for automatic reactor trips, the improved RTB maintenance activities developed over the past
several years, and the implementation of 10 CFR 50.62 requirements
have file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (77 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval improved RTB reliability. These features are unaffected by the proposed changes. Excessive RTB testing results in increased component wear and possibly reduced component life. Testing the RTBs with associated logic trains reduces the potential for human errors and associated plant
The consequences of accidents previously evaluated are unaffected by the proposed changes.
- 2. Does not create the possibility of a new or different kind of
accident from any accident previously evaluated.
The proposed changes do not modify any system or equipment, nor
alter any process function. The Manual Reactor Trip Switch and RTB
functionality remains unchanged. Therefore these changes do not create a new or un-evaluated accident or operating condition.
- 3. Does not involve a significant reduction in a margin of safety.
The proposed changes adopt the NRC approved Westinghouse STS
surveillance testing frequencies to maintain RTB reliability. Reduced
testing at power, consistent with the associated logic train test
frequency, reduces the potential for inadvertent actuation and
personnel errors. Thus, the proposed changes enhance plant 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)

The proposed changes do not involve a significant hazards
considerations because the changes would not:
- 1. Involve a significant increase in the probability or
consequences of an accident previously evaluated.
The activities associated with characterization of the facility
will have a minimum impact on the physical condition of the
containment
vessel as it relates to the risk of fire and has no effect on the risk of flooding.
- 2. Create the possibility of a new or different kind of accident
from any previously analyzed.
In its present condition, the only accidents applicable to the
site are fire, flood, and radiological hazard. The possibility of a new or
different type of accident than that previously evaluated in the FSAR
will not be created by the implementation of activities permitted by
the approval of this amendment request.
- 3. Involve a significant reduction in a margin of safety.
No margins of safety relevant to the equipment at the facility
exist. Activities involved in characterization will not involve a
reduction in a margin of safety.
The NRC staff has reviewed the analysis of the licensee and, based
on this review, it appears that the three standards of 50.92(c) are

Date of amendment request: August 26, 1994.
Description of amendment requests: The licensee proposes to revise Technical Specification (TS) 3/4.7.5, ``Control Room Emergency Air
Cleanup System. The proposed revision to TS 3/4.7.5 will provide a
Limiting Condition of Operation (LCO) 3.0.4 exception for MODES 5, 6, or a defueled configuration.
Basis for proposed no significant hazards consideration
determination: 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. Will operation of the facility in accordance with this proposed
change involve a significant increase in the probability or consequences of any accident previously evaluated?
Response:
No.
The Control Room Emergency Air Cleanup System (CREACUS) provides a
protected environment from which operators can control the plant
following an uncontrolled release of radioactivity or toxic gas.
[The following are the proposed changes to Technical Specification
3/4.7.5 ``Control Room Emergency Air Cleanup System:]
Proposed Change 1 [adds the following statement to the
Applicability statement of TS 3.7.5: ``or during movement of
irradiated
fuel assemblies.] will replace the existing wording of the
Applicability with the following words ``ALL MODES or during movement
of irradiated fuel assemblies. The requirement concerning movement of irradiated fuel assemblies was added because the existing
Applicability
statement does not reflect the possibility of radiation exposure to
the operators inside the control room during this event. A fuel handling
accident can happen during defueled operations. In this case, movement
of the last irradiated fuel assembly from the empty core inside
containment is not covered by the existing Applicability.
Also, a fuel handling accident can happen inside the Fuel Handling
Building when irradiated fuel is moved from one location to another in
the Spent Fuel Pool (SEP). The need for the CREACUS during fuel
handling is based on safety analysis assumptions which are specified
in Chapter 15 of the SONGS Unit 2 and 3 Updated Final Safety Analysis
Report (UFSAR).
file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (80 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval Addition of the new Applicability requirement will not involve a significant increase in the possibility or consequences of any
accident previously evaluated.
Proposed Change 2 [a new Action d): ``The provisions of
Specification 3.0.4 are not applicable when entering MODES 5, 6, or
defueled configuration is added to the Action section of TS 3.7.5]
will add a new Action d) which reads: ``the provisions of Specification
3.0.4 are not applicable when entering MODES 5, 6, or defueled
configuration. Existing Technical Specification 3/4.7.5 prohibits
entering MODE 6 from a defueled configuration unless both CREACUS
trains are OPERABLE. With the addition of the statement ``or during
movement of irradiated fuel assemblies to the Applicability, OPERABILITY of the CREACUS will be ensured prior to movement of irradiated fuel assemblies. Therefore, the only threshold between
defueled configuration and MODE 6 is the position of the first
irradiated fuel assembly--whether it is in the reactor vessel or
external to it. This threshold has no safety significance because the
only credible event during the transition from a defueled
configuration
to MODE 6 and from MODE 6 to defueled configuration is a Design Basis
Fuel Handling Accident which is covered by the proposed Applicability.
Therefore, this threshold can be expected from Limiting Condition for
Operation (LCO) 3.0.4.
The threshold of entering MODE 5 from MODE 6 consists of fully
tightening the last reactor vessel head closure bolt. This evolution has no safety significance from the point of view of isolating the
control room from external hazards. Therefore, this MODE change can be
excepted from LCO 3.0.4. The threshold of entering MODE 6 from MODE 5
consists of untightening at least one reactor vessel head closure
bolt.
If no irradiated fuel assemblies are being moved, this evolution has
no safety significance from the point of view of isolating the control
room from external hazards. Therefore, this MODE change can be
excepted from LCO 3.0.4 also.
The threshold of entering MODE 5 from MODE 4 consists of
decreasing
Reactor Coolant System (RCS) temperature from 350 deg.F > Tavg >
200 deg.F to Tavg [less than or equal to] 200 deg.F by initiating
shutdown cooling. If no irradiated fuel assemblies are being moved, file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (81 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval this evolution has no safety significance from the point of view of isolating the control room from external hazards. Therefore, this MODE
change can be excepted from LCO 3.0.4.
The MODE changes have no significance relative to releases.
Therefore, since CREACUS can be inoperable during each individual
- mode, it should not be required to have two OPERABLE CREACUS trains before
mode changes.
Therefore, addition of the new Action will not involve a
significant increase in the probability or consequences of any
accident previously evaluated.
Proposed Change 3 [adds the following words ``or defueled
configuration when moving irradiated fuel assemblies after the words
``Units 2 and 3 in MODE 5 or 6 in the Action statement of TS 3.7.5]
will add the words ``or defueled when moving irradiated fuel
assemblies to the Action statement when either Unit is in MODE 5 or
- 6. These words are added for consistency with a proposed Applicability
statement ``or during movement of irradiated fuel assemblies.
Without these words it is not clear what Actions should be entered if the LCO
requirement is not met in a defueled configuration when moving
irradiated fuel assemblies. By adding these words Actions (a) and (b)
became applicable in a defueled configuration when moving irradiated
fuel assemblies. This change applies the requirement of the proposed
Applicability to the Action when either Unit is in MODES 5 or 6.
Therefore, addition of these words to the Action statement will not involve a significant increase in the probability or consequences of
any accident previously evaluated.
Proposed Change 4 [adds the following words ``or movement of
irradiated fuel assemblies after the words ``suspend all operations
involving CORE ALTERATIONS or positive reactivity changes in the
Action (b) statement of TS 3.7.5] will add the words ``or movement of
irradiated fuel assemblies in the Action (b) statement. These words
are added for consistency with the proposed Applicability statement
and proposed Action statement when either Unit is in MODES 5 or 6, or a
defueled configuration when moving irradiated fuel assemblies. Without
addition of these words Action (b) did not specify what should be done
when any Unit is in a defueled configuration when moving irradiated
fuel assemblies. Therefore, addition of these words to the Action
statement will not involve a significant increase in the probability

- 2. Will operation of the facility in accordance with this proposed
change create the possibility of a new or different kind of accident from any previously evaluated?
Response:
No.
The changes proposed herein do not reduce the reliability or
performance of the Control Room Emergency Air Cleanup System (CREACUS).
The proposed LCO 3.0.4 exception for CREACUS permits MODE 5, MODE 6, or defueled configuration entry with one train of CREACUS inoperable.
This change does not affect CREACUS reliability and its capability to
perform its intended design functions.
Additional requirements in the Applicability to have two Control Room Emergency Air Cleanup Systems OPERABLE during movement of
irradiated fuel covers the consequences of a fuel accident in the Fuel
Handling Building and in containment when the reactor vessel is
defueled. Operation of the facility will remain unchanged as a result
of the proposed changes.
Also, addition of the requirement to suspend movement of
irradiated
fuel assemblies when either Unit is in a defueled configuration when
moving irradiated fuel is made for consistency with the proposed
Applicability statement and Action statement. The proposed Action
statement emphasize that Actions (a) and (b) are applicable not only
when either Unit is in MODES 5 or 6, but also when in a defueled configuration when moving irradiated fuel assemblies. This change does
not affect CREACUS reliability and its capability to perform its
intended design functions. Therefore, the proposed changes will not
create the possibility of a new or different kind of accident from any
accident previously evaluated.
- 3. Will operation of the facility in accordance with this proposed
change involve a significant reduction in a margin of safety?
Response:
No.
Operation of the facility in accordance with these changes will
not be adversely affected as a result of the changes proposed herein. The
proposed changes include a change to the Applicability, adding the new
Action (d), modifying the Action statement when either Unit is in
MODES 5 or 6, and modifying the Action (b). The proposed LCO 3.0.4 exception
for CREACUS permits MODE 5, MODE 6, or defueled configuration entry file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (83 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval with one train of CREACUS inoperable. Additional requirements in the Applicability statement to have two Control Room Emergency Air Cleanup
Systems OPERABLE during movement of irradiated fuel, covers the consequences of the fuel accident in the Fuel Handling Building. Also, this requirement covers the movement of irradiated fuel when the
reactor vessel is defueled. Modified Action statement for either Unit
in MODES 5 or 6 is made for consistency with the proposed
Applicability statement. Modified Action (b) covers the possibility of both the
CREACUS trains being inoperable in a defueled configuration when
moving irradiated fuel assemblies.
The margin of safety as defined in Bases 3/4.7.5 is limiting the
dose to control room personnel to 5.0 rem or less whole body, or its equivalent. As discussed above, operation of the CREACUS will be unchanged as a result of the proposed changes. Therefore, operation of
the facility in accordance with this proposed change will 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 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment requests involve no significant hazards consideration.

San Onofre Nuclear Generating Station, Unit Nos. 2 and 3, San Diego County, California.
Date of amendment requests: September 16, 1994.
Description of amendment requests: The licensee proposes to revise
the linear heat rate (LHR) limit in Technical Specification (TS) 3/
4.2.1, ``Linear Heat Rate. TS 3/4.2.1 requires maintaining the LHR
at or below 13.9 kilowatts per linear foot (kw/ft) for steady-state
operation. This amendment request is to revise this value from 13.9 kw/

Basis for proposed no significant hazards consideration determination: 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. Will operation of the facility in accordance with this proposed
change involve a significant increase in the probability or consequences of any accident previously evaluated?
Response:
No.
The only event impacted by this Technical Specification (TS)
change is the Large Break Loss of Coolant Accident (LBLOCA) which has been
reanalyzed. There is a direct correlation between the magnitude of the TS 3/4.2.1 Linear Heat Rate (LHR) limit and the calculated peak cladding temperature (PCT). Since the LHR is being reduced in value, which is a conservative change, there will be no increase in the
consequences of the event. The LBLOCA reanalysis, performed using the
new LHR limit in support of an optimized fuel loading pattern, resulted in a reduction of the calculated LBLOCA PCT. Therefore, this change
will not involve an increase in the probability or consequences of any
accident previously evaluated.
- 2. Will operation of the facility in accordance with this proposed
change create the possibility of a new or different kind of accident
from any previously evaluated?
Response:
No. This amendment request does not involve any change to plant
equipment or operation. The linear heat rate limit provided in T/S
3.2.1 is used only in the LBLOCA analysis.
No change to the LBLOCA
methodology was made. Therefore, this change does not create the
possibility of a new or different kind of accident from any previously
evaluated.
- 3. Will operation of the facility in accordance with this proposed
change involve a significant reduction in a margin of safety?
Response:
No.
This amendment does not change the manner in which safety limits, limiting safety settings, or limiting conditions for operation are
determined. There is no change in the PCT acceptance criterion for
this event as a result of the proposed reduction in the LHR limit.
Therefore, there is no reduction in the margin of safety from the
acceptance limit to the mechanical failure point of the fuel.
file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (85 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval Additionally, the analysis value for the LBLOCA PCT is reduced to 2160 deg.F. This results in an increase in the analysis margin between the
acceptance criterion and the analysis value. Therefore, this proposed change does not involve a 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 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment requests involve no significant hazards consideration.

Toledo Edison Company, Centerior Service Company, and The Cleveland Electric Illuminating Company Docket No. 50-346 Davis-Besse Nuclear Power Station, Unit No. 1, Ottawa County, Ohio.
Date of amendment request: October 7, 1994.
Description of amendment request: The proposed amendment would
remove the existing Surveillance Requirement (SR) 4.5.2.d.3 for the
Low Pressure Injection (LPI) System and the existing SR 4.6.2.1.c for the
Containment Spray (CS) System since the requirement to leak test these
systems is programmatically covered in TS 6.8.4.a, ``Primary Coolant Sources Outside Containment. Additionally, changes are proposed to
TS Bases 3/4.5.2 and 3/4.6.2.1 to reflect the elimination of the above
SRs.
Basis for proposed no significant hazards consideration
determination: As required by 10 CFR 50.91(a), the NRC staff has
reviewed the licensee's analysis against the standards of 10 CFR
50.92(c). The staff's review is presented below:
(1) The proposed changes do not involve a significant increase in
the probability or consequences of an accident previously evaluated.
The change does not involve a significant increase in the
probability of an accident previously evaluated nor does it involve a
significant increase in the consequences of an accident previously
evaluated because no accident initiators, conditions or assumptions
are affected by removing the leak test requirements of LPI System SR file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (86 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval 4.5.2.d.3 and CS System SR 4.6.2.1.c. The purpose of these SRs is already encompassed by the existing program requirements of TS 6.8.4.
a, ``Primary Coolant Sources Outside Containment. TS 6.8.4.a requires integrated leak testing at refueling cycle intervals or less, for each
system outside containment, that could contain highly radioactive
fluids during a serious transient or accident.
The proposed changes do not alter the source term, containment isolation, or allowable releases. The proposed changes, therefore, will not increase the radiological consequences of a previously evaluated
event.
These changes are consistent with NUREG-1430, Revision 0,
``Improved Standard Technical Specifications for B&W Plants. The associated changes to TS Bases 3/4.5.2 and 3/4.6.2.1 are administrative.
(2) The proposed changes do not create the possibility of a new or
different kind of accident from any accident previously evaluated.
The proposed changes do not create the possibility of any new or
different kind of accident from any accident previously evaluated
because no new accident initiators or assumptions are introduced by
these proposed changes to LPI System SR 4.5.2.d.3 and CS System SR 4.6.2.1.c. The purpose of these SRs is already encompassed by the
existing program requirements of TS 6.8.4.a, ``Primary Coolant Sources
Outside Containment, which requires leak testing to be performed on
the LPI and CS Systems. These changes are consistent with NUREG-1430.
The associated changes to TS Bases 3/4.5.2 and 3/4.6.2.1 are administrative. The proposed changes do not alter any accident
scenarios.
(3) The proposed changes do not result in a significant reduction
in the margin of safety.
The changes do not involve a significant reduction in the margin
of safety because the proposed changes to the LPI System SR 4.5.2.d.3 and
CS System SR 4.6.2.1.c do not reduce or adversely affect the
capabilities of any plant structures, systems or components. The
purpose of these SRs is already encompassed by the existing program
requirements of TS 6.8.4.a, ``Primary Coolant Sources Outside
Containment. These changes are consistent with NUREG-1430. The
associated changes to TS Bases 3/4.5.2 and 3/4.6.2.1 are
administrative.
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) file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (87 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval are satisfied. Therefore, the NRC staff proposes to determine that the

Surry Power Station, Unit Nos. 1 and 2, Surry County, Virginia.
Date of amendment request: October 11, 1994.
Description of amendment request: The proposed changes would
modify the surveillance frequencies of the containment hydrogen analyzers.
Basis for proposed no significant hazards consideration
determination: 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:
Specifically, operation of Surry Power Station in accordance with
the proposed Technical Specifications will not:
- 1. Involve a significant increase in the probability of occurrence
or consequences of an accident previously evaluated.
The proposed changes to the surveillance requirements for the
hydrogen analyzers have no impact on the probability of any accident occurrence. The hydrogen analyzers are maintained in a standby mode
during normal operation and are made fully operable within thirty
minutes after a safety injection signal to provide indication of the
hydrogen concentration in containment after a loss-of-coolant
accident.
This instrumentation is used solely post-accident to monitor
containment conditions. Reduced testing of a post-accident monitor
does not contribute to the probability of any previously analyzed accident.
These monitors have no automatic safety function. Furthermore, the
hydrogen analyzers will be operated in the same manner, and the
operability requirements are not being altered. In addition, the Post-
Accident Sampling System serves as a diverse means to confirm post-
accident hydrogen concentration in containment. Therefore, the
consequences of a Design Basis Accident are not being increased by the file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (88 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval proposed change in surveillance test frequency of the hydrogen analyzers.
Reducing the frequency of surveillance testing could however decrease the timeliness in identifying an inoperable hydrogen analyzer.
However, our surveillance test experience has shown that the analyzers
have been very stable with repeatable results, and we conclude that
the change in test frequency should not affect the reliability or
operability of the analyzers. Likewise, the NRC has determined in
Generic Letter 93-05 that a reduced frequency of surveillance testing
during power is acceptable to determine hydrogen analyzer operability.
- 2. Create the possibility of a new or different kind of accident
from any accident previously evaluated.
There are no plant modifications or changes in methods of plant operation introduced by this change in hydrogen analyzer surveillance
frequencies. The hydrogen analyzers are maintained in a standby mode
during normal operation and are fully operable within thirty minutes
after a safety injection signal to provide indication of the hydrogen
concentration in containment after a loss-of-coolant accident.
Therefore, the possibility of a new or different kind of accident than
previously evaluated is not created by the proposed changes in
surveillance frequency of the control rods [hydrogen analyzers
surveillance frequencies].
- 3. Involve a significant reduction in a margin of safety.
The hydrogen analyzer surveillance requirements do not affect the
margin of safety in that the operability requirements for the safety systems and containment remain unchanged. The hydrogen analyzers only
provide indication and do not perform any direct function to mitigate
the consequences of any previously analyzed accidents. Furthermore, the change in surveillance frequency is associated with a post-accident
monitor with no automatic safety functions and a diverse means of
confirming the parameter by the Post-Accident Sampling System.
Therefore, the margin of safety is not altered by this proposed change
in the surveillance frequencies of the hydrogen analyzers.
The NRC staff has reviewed the licensee's analysis and, based on
this review, it appears that the three standards of 50.92(c) are
satisfied. Therefore, the NRC staff proposes to determine that the
amendment request involves no significant hazards consideration.

Notice of Issuance of Amendments to Facility Operating Licenses and Final Determination of No Significant Hazards Consideration and
Opportunity for a Hearing (Exigent Public Announcement or Emergency
Circumstances)
During the period since publication of the last biweekly notice, the Commission has issued the following amendments. The Commission has
determined for each of these amendments that the application for the
amendment complies with the standards and requirements of the Atomic
Energy Act of 1954, as amended (the Act), and the Commission's rules
and regulations. The Commission has made appropriate findings as
required by the Act and the Commission's rules and regulations in 10
CFR Chapter I, which are set forth in the license amendment.
Because of exigent or emergency circumstances associated with the
date the amendment was needed, there was not time for the Commission
to publish, for public comment before issuance, its usual 30-day Notice
of Consideration of Issuance of Amendment, Proposed No Significant
Hazards Consideration Determination, and Opportunity for a Hearing.
file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (106 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval For exigent circumstances, the Commission has either issued a Federal Register notice providing opportunity for public comment or
has used local media to provide notice to the public in the area surrounding a licensee's facility of the licensee's application and of
the Commission's proposed determination of no significant hazards
consideration. The Commission has provided a reasonable opportunity
for the public to comment, using its best efforts to make available to the
public means of communication for the public to respond quickly, and
in the case of telephone comments, the comments have been recorded or
transcribed as appropriate and the licensee has been informed of the
public comments.
In circumstances where failure to act in a timely way would have resulted, for example, in derating or shutdown of a nuclear power
plant or in prevention of either resumption of operation or of increase in
power output up to the plant's licensed power level, the Commission
may not have had an opportunity to provide for public comment on its no significant hazards consideration determination. In such case, the
license amendment has been issued without opportunity for comment. If
there has been some time for public comment but less than 30 days, the
Commission may provide an opportunity for public comment. If comments
have been requested, it is so stated. In either event, the State has
been consulted by telephone whenever possible.
Under its regulations, the Commission may issue and make an
amendment immediately effective, notwithstanding the pendency before
it of a request for a hearing from any person, in advance of the holding
and completion of any required hearing, where it has determined that
no significant hazards consideration is involved.
The Commission has applied the standards of 10 CFR 50.92 and has
made a final determination that the amendment involves no significant
hazards consideration. The basis for this determination is contained
in the documents related to this action. Accordingly, the amendments have
been issued and made effective as indicated.
Unless otherwise indicated, the Commission has determined that
these amendments satisfy the criteria for categorical exclusion in
accordance with 10 CFR 51.22. Therefore, pursuant to 10 CFR 51.22(b), file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (107 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval no environmental impact statement or environmental assessment need be prepared for these amendments. If the Commission has prepared an
environmental assessment under the special circumstances provision in 10 CFR 51.12(b) and has made a determination based on that assessment, it is so indicated.
For further details with respect to the action see (1) the
application for amendment, (2) the amendment to Facility Operating
License, and (3) the Commission's related letter, Safety Evaluation and/or Environmental Assessment, as indicated. All of these items are
available for public inspection at the Commission's Public Document
Room, the Gelman Building, 2120 L Street, NW., Washington, DC 20555, and at the local public document room for the particular facility
involved.
The Commission is also offering an opportunity for a hearing with respect to the issuance of the amendment. By December 9, 1994, 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 2.714 which is available at the
Commission's Public Document Room, the Gelman Building, 2120 L Street, NW., Washington, DC 20555 and at the local public document room for
the particular facility involved. If a request for a hearing or petition
for leave to intervene is filed by the above date, the Commission or
an Atomic Safety and Licensing Board, designated by the Commission or by
the Chairman of the Atomic Safety and Licensing Board Panel, will rule
on the request and/or petition; and the Secretary or the designated
Atomic Safety and Licensing Board will issue a notice of a hearing or
an appropriate order.
As required by 10 CFR 2.714, 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 factors: (1) The nature of the petitioner's right under the
Act to be made a party to the proceeding; (2) the nature and extent of file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (108 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval the petitioner's property, financial, or other interest in the proceeding; and (3) the possible effect of any order which may be
entered in the proceeding on the petitioner's interest. The petition should also identify the specific aspect(s) of the subject matter of the proceeding as to which petitioner wishes to intervene. Any person
who has filed a petition for leave to intervene or who has been
admitted as a party may amend the petition without requesting leave of
the Board up to 15 days prior to the first prehearing conference scheduled in the proceeding, but such an amended petition must satisfy
the specificity requirements described above.
Not later than 15 days prior to the first prehearing conference
scheduled in the proceeding, a petitioner shall file a supplement to
the petition to intervene which must include a list of the contentions
which are sought to be litigated in the matter. Each contention must consist of a specific statement of the issue of law or fact to be raised or controverted. In addition, the petitioner shall provide a
brief explanation of the bases of 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 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. Petitioner 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 to relief. A
petitioner who fails to file such a supplement which satisfies 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, including the opportunity to present evidence and cross-
examine witnesses. Since the Commission has made a final determination
that the amendment involves no significant hazards consideration, if a
hearing is requested, it will not stay the effectiveness of the
amendment. Any hearing held would take place while the amendment is in
effect.
A request for a hearing or a petition for leave to intervene must
be filed with the Secretary of the Commission, U.S. Nuclear Regulatory
Commission, Washington, DC 20555, Attention: Docketing and Services file:///Gl/ADRO/DLR/REBA_Under_Eric/Sarah Lopas/59 FR 12990.htm (109 of 111)4/12/2007 5:32:58 PM WAIS Document Retrieval Branch, or may be delivered to the Commission's Public Document Room, the Gelman Building, 2120 L Street, NW., Washington, DC 20555, by the
above date. Where petitions are filed during the last 10 days of the notice period, it is requested that the petitioner promptly so inform the Commission by a toll-free telephone call to Western Union at 1-
(800) 248-5100 (in Missouri 1-(800) 342-6700). The Western Union
operator should be given Datagram Identification Number N1023 and the
following message addressed to (Project Director): petitioner's name and telephone number, date petition was mailed, plant name, and
publication date and page number of this Federal Register notice. A
copy of the petition should also be sent to the Office of the General
Counsel, U.S. Nuclear Regulatory Commission, Washington, DC 20555, and
to the attorney for the licensee.
Nontimely filings of petitions for leave to intervene, amended petitions, supplemental petitions and/or requests for a hearing will not be entertained absent a determination by the Commission, the
