[[Page 52987]]
SUMMARY: The NRC is requesting public comment on the enclosed proposed
model safety evaluation, model no significant hazards consideration
determination, and model application for plant-specific adoption of
Technical Specification Task Force (TSTF) Traveler-508, Revision 1,
``Revise Control Room Habitability Actions to Address Lessons Learned
from TSTF-448 Implementation.'' The TSTF Traveler-508, Revision 1, is
available in the Agencywide Documents Access Management System (ADAMS)
under Accession Number ML091690643. The proposed changes would revise
Technical Specification (TS) [3.7.10, ``Control Room Emergency
Filtration System]'' the Bases for TS [3.7.10], and TS [5.5.18],
``Control Room Envelope Habitability Program,'' to pursue TS
improvements consistent with the justification in TSTF-448, Revision 3,
``Control Room Habitability,'' while addressing inconsistencies with
TSTF Traveler-448. This model safety evaluation will facilitate
expedited approval of plant-specific adoption of TSTF Traveler-508,
Revision 1.

SUPPLEMENTARY INFORMATION:
Background
This notice provides an opportunity for the public to comment on
proposed changes to the Standard TS (STS) after a preliminary
assessment and finding by the NRC staff that the agency will likely
offer the changes for adoption by licensees. This notice solicits
comment on a proposed change to the STS that modifies the TS. The NRC
staff will evaluate any comments received for the proposed change to
the STS and reconsider the change or announce the availability of the
change for adoption by licensees. Licensees opting to apply for this TS
change are responsible for reviewing the NRC staff's evaluation,
referencing the applicable technical justifications, and providing any
necessary plant-specific information. The NRC will process and note
each amendment application responding to the notice of availability
according to applicable NRC rules and procedures.
Applicability
TSTF Traveler-508, Revision 1, is applicable to pressurized and
boiling water reactors. The Traveler revises the TS and TS Bases for TS
[3.7.10] Condition B, TS [3.7.10] Condition [E], and TS [5.5.18],
``Control Room Habitability Program.''
The proposed change does not prevent licensees from requesting an
alternate approach or proposing changes other than those proposed in
TSTF Traveler-508, Revision 1. However, significant deviations from the
approach recommended in this notice or the inclusion of additional
changes to the license require additional NRC staff review. This may
increase the time and resources needed for the review or result in NRC
staff rejection of the LAR. Licensees desiring significant deviations
or additional changes should instead submit an LAR that does not claim
to adopt TSTF Traveler-508, Revision 1.
Dated at Rockville, Maryland, this 1st day of October 2009.
For the Nuclear Regulatory Commission.
Stacey L. Rosenberg,
Chief, Special Projects Branch, Division of Policy and Rulemaking,
Office of Nuclear Reactor Regulation.
The following example of an application was prepared by the NRC
staff to facilitate the adoption of technical specifications task
force (TSTF) Traveler-508, Revision 1, ``Revise control room
habitability actions to address lessons learned from TSTF-448
implementation.'' The model provides the expected level of detail
and content for an application to adopt Traveler-508, Revision 1.
Licensees remain responsible for ensuring that their actual
application fulfills their administrative requirements as well as
NRC regulations.

[[Page 52989]]
implementation of TS changes based on TSTF Traveler-508, Revision 1].
[Provide discussion and justification for any plant-specific items
not addressed in the NRC staff's model safety evaluation.]
5.0 Regulatory Analysis
5.1 No Significant Hazards Determination
[LICENSEE] has reviewed the no significant hazards determination
published on [DATE] ([ ] FR [ ]) as part of the CLIIP Notice of
Availability. [LICENSEE] and has concluded that the determination
presented in the notice is applicable to [PLANT, UNIT NO.]. [LICENSEE]
has evaluated the proposed changes to the TS using the criteria in 10
CFR 50.92 and has determined that the proposed changes do not involve a
significant hazards consideration. An analysis of the issue of no
significant hazards consideration is presented below:
[LICENSEE INSERT ANALYSIS HERE.]
5.2 Applicable Regulatory Requirements/Criteria
A description of this proposed change and its relationship to
applicable regulatory requirements and guidance was provided in the NRC
Notice of Availability published on [DATE] ([ ] FR [ ]), and TSTF-508,
Revision 1. [LICENSEE] has reviewed the NRC staff's model safety
evaluation published on [DATE] ([ ] FR[ ]) as part of the CLIIP Notice
of Availability and concluded that the regulatory evaluation section is
applicable to [PLANT, UNIT NO.]
6.0 Environmental Evaluation
[LICENSEE] has reviewed the environmental consideration included in
the model SE published in the Federal Register on [DATE] ([ ] FR [ ])
as part of the CLIIP. [LICENSEE] has concluded that the staff's
findings presented therein are applicable to [PLANT] and the
determination is hereby incorporated by reference for this application.
The proposed change would change a requirement with respect to
installation or use of a facility component located within the
restricted area, as defined in 10 CFR part 20, and would change an
inspection or surveillance requirement. However, the proposed change
does not involve (i) a significant hazards consideration, (ii) a
significant change in the types or significant increase in the amounts
of any effluent that may be released offsite, or (iii) a significant
increase in individual or cumulative occupational radiation exposure.
Accordingly, the proposed change meets the eligibility criterion for
categorical exclusion set forth in 10 CFR 51.22(c)(9). Therefore,
pursuant to 10 CFR 51.22(b), no environmental impact statement or
environmental assessment need be prepared in connection with the
proposed change.

1.0 Introduction
By letter dated [DATE], [LICENSEE] (the licensee) proposed changes
to the technical specifications (TS) for [PLANT NAME]. The proposed
changes would allow [PLANT NAME] to address inconsistencies in
Technical Specification Task Force (TSTF) Improved Standard Technical
Specification (STS) Change Traveler-448, Revision 3.
The proposed changes would revise TS [3.7.10] Condition B as
follows:
Delete the mode restrictions in the Condition statement.
Add new Required Action B.[2] which requires immediate
suspension of movement of [recently] irradiated fuel.
[add new Required Action B.[3], which requires immediate
initiation of actions to suspend OPDRVs.]
Renumber Required Actions in Condition B.
Change language in renumbered Required Action B.[4] from,
``verify mitigating actions ensure CRE occupant exposures to
radiological, chemical, and smoke hazards will not exceed limits.'' to
``verify mitigating actions ensure CRE occupant radiological exposures
will not exceed limits, and CRE occupants are protected from chemical
and smoke hazards.''
The proposed changes would revise TS [3.7.10] Condition [E] as
follows:
Add the phrase ``for conditions other than Condition B.''
to the end of the first Condition statement.
Change the second Condition statement to ``[Required
Actions and associated Completion Times of Condition B not met [in MODE
5 or 6, or] during movement of [recently] irradiated fuel assemblies./
Required Actions and associated Completion Times of Condition B not met
during movement of [recently] irradiated fuel assemblies in the
[secondary/primary or secondary] containment or during OPDRVs.]''
The proposed changes would revise TS [5.5.18], ``Control Room
Habitability Program'' as follows:
Revise the last sentence of paragraph [d] of TS [5.5.18],
``Control Room Habitability Program'' from ``The results shall be
trended and used as part of the [18] month assessment of the CRE
boundary.'' to ``The results shall be trended and used as part of the
periodic assessment of the CRE boundary.''
The licensee stated that the application is consistent with NRC-
approved Revision 1 to TSTF Traveler-508, Revise Control Room
Habitability Actions to Address Lessons Learned from TSTF-448
Implementation.'' [Discuss any differences with TSTF-508, Revision 1.]
The availability of this TS improvement was announced in the Federal
Register on [Date] ([ ] FR [ ]) as part of the consolidated line item
improvement process (CLIIP).
2.0 Regulatory Evaluation
Section 182a of the Atomic Energy Act (the ``Act'') requires
applicants for nuclear power plant operating licenses to include TS as
part of the license. The TS ensure the operational capability of
structures, systems and components that are required to protect the
health and safety of the public. The Commission's regulatory
requirements related to the content of the TS are contained in Title 10
of the Code of Federal Regulations (10 CFR) Section 50.36. This
regulation requires that the TS include items in the following specific
categories: (1) Safety limits, limiting safety systems settings, and
limiting control settings (10 CFR 50.36(c).(1)); (2) limiting
conditions for operation (10 CFR 50.36(c).(2)); (3) surveillance
requirements (10 CFR 50.36(c)(3)); (4) design features (10 CFR
50.36(c)(4)); and (5) administrative controls (10 CFR 50.36(c).(5)).
In general, there are two classes of changes to TS: (1) Changes
needed to reflect modifications to the design basis (TS are derived
from the design basis), and (2) voluntary changes to take advantage of
the evolution in policy and guidance as to the required content and
preferred format of TS over time. This amendment deals with the second
class of changes.
Licensees may revise the TS to adopt current improved STS format
and content provided that plant-specific review supports a finding of
continued
[[Page 52990]]
adequate safety because: (1) The change is editorial, administrative or
provides clarification (i.e., no requirements are materially altered);
(2) the change is more restrictive than the licensee's current
requirement; or (3) the change is less restrictive than the licensee's
current requirement, but nonetheless still affords adequate assurance
of safety when judged against current regulatory standards. The
detailed application of this general framework, and additional
specialized guidance, are discussed in Section 3.0 in the context of
specific proposed changes.
3.0 Technical Evaluation
The NRC staff has found changes made by TSTF Traveler-508, Revision
1, to the STS, as amended by TSTF Traveler-448, Revision 3, to satisfy
applicable regulatory requirements, as described above in Section 2.0.
The NRC staff reviewed the licensee's proposed TS changes against the
corresponding changes made by TSTF Traveler-508, Revision 1.
3.1 Proposed Changes
The NRC staff compared the proposed TS changes to the STS and the
STS markups and evaluations in TSTF Traveler-508. [The NRC staff
verified that differences from the STS as amended by TSTF Traveler-448
were adequately justified on the basis of plant-specific design or
retention of current licensing basis.] The NRC staff also reviewed the
proposed changes to the TS Bases for consistency with the STS Bases and
the plant-specific design and licensing bases, although approval of the
TS Bases is not a condition for accepting the proposed amendment.
3.2 TS [3.7.10, ``Control Room Emergency Ventilation System (CREVS)]
Condition B
As stated in Section 1.0, the licensee proposed several changes to
Condition B. The first proposed change would delete the phrase ``in
MODE 1, 2, 3, or 4'' from the Condition B statement. This change would
mean the licensee would have to complete the Required Actions of
Condition B within the associated Completion Times while in all MODES
and situations listed in the APPLICABILITY statement. The licensee also
proposed adding new Required Action B.2 and a Note as well as
renumbering Required Actions B.2 and B.3. New Required Action B.2
requires the licensee to immediately suspend movement of [recently]
irradiated fuel assemblies when one or more [CREVS] is inoperable due
to an inoperable Control Room Envelope (CRE) boundary. The Note above
new Required Action B.[2] states ``Not required following completion of
Required Action B.[3].'' [The licensee also proposed adding new
Required Action B.3 and a Note. New Required Action B.3 requires the
licensee to immediately initiate action to suspend Operations with the
Potential to Drain the Reactor Vessel (OPDRVs) when one or more [CREVS]
is inoperable due to an inoperable Control Room Envelope (CRE)
boundary. The Note above new Required Action B.3 states ``Not required
following completion of Required Action B.[4].] Finally, the licensee
proposed rewording the renumbered Required Action [3] from ``Verify
mitigating actions ensure CRE occupant exposures to radiological,
chemical, and smoke hazards will not exceed limits'' to ``Verify
mitigating actions ensure CRE occupant radiological exposures will not
exceed limits, and CRE occupants are protected from chemical and smoke
hazards.''
The NRC staff reviewed the licensee's proposed TS changes. The NRC
staff determined that the removal of MODE restrictions and the addition
of the [two] new Required Action[s] constituted a relaxation compared
to the STS as amended by TSTF Traveler-448. The NRC staff also
determined that the STS as amended by TSTF Traveler-448 were overly
restrictive in that movement of [irradiated] fuel [and OPDRVs] is [are]
not allowed when a CRE is inoperable, even if compensatory measures are
taken to confirm CRE occupants will be protected in the event of a
Design Basis Accident (DBA). The NRC staff determined that the
relaxation is justified and acceptable because the addition of the new
Required Action[s] ensure that CRE occupants would continue to be
protected from radiological, chemical, and smoke hazards during the
time a CRE may be inoperable. The NRC staff also determined that
changing the language of Required Action B.[3] was acceptable since
quantifiable limits on smoke and chemicals hazards do not exist in the
safety evaluation for TSTF Traveler-448, and the proposed change
addresses the inconsistency between the STS as amended by TSTF
Traveler-448 and the model safety evaluation for TSTF Traveler-448.
3.3 TS [3.7.10, ``Control Room Emergency Ventilation System (CREVS)'']
Condition [E]
The licensee proposed rewording the two condition statements
separated by the OR operator that make up Condition [E] of TS [3.7.10].
The proposed changes are necessary to make the conditions consistent
with the removal of the MODE restrictions of Condition B. Condition [E]
is currently worded as such: ``[Two CREVS trains inoperable [in MODE 5
or 6, or] during movement of [recently] irradiated fuel assemblies [in
the secondary containment or during OPDRVs] OR One or more CREVS trains
inoperable due to an inoperable CRE boundary [in MODE 5 or 6, or]
during movement of [recently] irradiated fuel assemblies [in the
secondary containment or during OPDRVs].'' The proposed rewording is:
``[Two CREVS trains inoperable [in MODE 5 or 6, or] during movement of
[recently] irradiated fuel assemblies [in the secondary containment or
during OPDRVs] for reasons other than Condition B OR Required Actions
and associated Completion Times of Condition B not met [in MODE 5 or 6,
or] during movement of [recently ] irradiated fuel assemblies [in the
secondary containment or during OPDRVs].''
The NRC staff reviewed the proposed rewording of Condition [E] and
determined that the rewording was editorial because it was necessary to
maintain consistency with the changes made to Condition B and no
requirements or restrictions on operations were altered. Therefore the
proposed changes are acceptable.
3.4 S [5.5.18], ``Control Room Habitability Program''
The licensee proposed replacing the term ``18 month'' with the term
``periodic'' in the last sentence of TS [5.5.18] Paragraph d. The NRC
staff determined that the term ``18 month'' in the last sentence of
Paragraph d of TS [5.518] was inconsistent with the licensee's Control
Room Habitability Program. The NRC staff determined that the STS, as
amended by TSTF Traveler-448 incorrectly used the term ``18 month'' to
describe the assessment referred to in the last sentence of Paragraph d
of the Control Room Habitability Program. The NRC staff determined that
the proposed change is editorial since no requirements are materially
altered and the change will address an inconsistency in TSTF Traveler-
448. Therefore the change is acceptable.
4.0 State Consultation
In accordance with the Commission's regulations, the [STATE NAME]
State official was notified of the proposed issuance of the amendment.
The State official had [(1) no comments or (2) the following comments--
with subsequent disposition by the NRC staff].
[[Page 52991]]
5.0 Environmental Consideration
The amendment[s] change[s] a requirement with respect to the
installation or use of a facility component located within the
restricted area as defined in 10 CFR part 20 or surveillance
requirements. The NRC staff has determined that the amendment involves
no significant increase in the amounts, and no significant change in
the types, of any effluents that may be released offsite, and that
there is no significant increase in individual or cumulative
occupational radiation exposure. The Commission has previously issued a
proposed finding that the amendment involves no significant hazards
consideration and there has been no public comment on such finding
published [DATE] ([ ] FR [ ]). Accordingly, the amendment meets the
eligibility criteria for categorical exclusion set forth in 10 CFR
51.22(c)(9). Pursuant to 10 CFR 51.22(b), no environmental impact
statement or environmental assessment need be prepared in connection
with the issuance of the amendment.
6.0 Conclusion
The NRC staff has concluded, based on the considerations discussed
above, that: (1) There is reasonable assurance that the health and
safety of the public will not be endangered by operation in the
proposed manner; (2) such activities will be conducted in compliance
with the Commission's regulations; and (3) the issuance of the
amendments will not be inimical to the common defense and security or
to the health and safety of the public.

Proposed Model No Significant Hazards Consideration Determination for
Plant-Specific Adoption of TSTF Traveler-508, Revision 1, ``Revise
Control Room Habitability Actions To Address Lessons Learned From TSTF-
448 Implementation''
Description of Amendment Request: [Plant name] requests adoption of
an approved change to the standard technical specifications (STS), as
amended by Technical Specification Task Force (TSTF) Standard Technical
Specification Change Traveler-448, Revision 3, ``Control Room
Habitability'' and TSTF Traveler-508, Revision 1, ``Revise Control Room
Habitability Actions to Address Lessons Learned from TSTF-448
Implementation.'' TSTF Traveler-508, Revision 1, revised the STS, as
previously amended by TSTF Traveler-448, Revision 3, to address
inconsistencies with TSTF Traveler-448, Revision 3. The licensee's
proposed changes are consistent with NRC-approved TSTF Traveler-508,
Revision 1.
Basis for proposed no significant hazards consideration
determination: As required by Title10 of the Code of Federal
Regulations (10 CFR) Section 50.91(a), the [LICENSEE] analysis of the
issue of no significant hazards consideration is presented below:
Criterion 1: Does the Proposed Change Involve a Significant
Increase in the Probability or Consequences of an Accident
Previously Evaluated?
Response: No.
The proposed changes do not adversely affect accident initiators
or precursors nor alter the design assumptions, conditions, or
configuration of the facility. The proposed changes do not alter or
prevent the ability of structures, systems, and components (SSCs) to
perform their intended function to mitigate the consequences of an
initiating event within the assumed acceptance limits. This is a
revision to the TSs for the control room ventilation system, which
is a mitigation system designed to minimize unfiltered air inleakage
into the control room envelope (CRE) and to filter the CRE
atmosphere to protect the CRE occupants following accidents
previously analyzed. An important part of the system is the CRE
boundary. Under the proposed change, the movement of irradiated fuel
and operations with the potential to drain the reactor vessel may be
resumed following confirmation that the CRE occupants will be
protected in the event of a DBA. This ensures that the consequences
of an accident previously evaluation are not significantly
increased. The CRE ventilation system is not an initiator or
precursor to any accident previously evaluated. Therefore, the
probability of any accident previously evaluated is not increased.
The consequences of an accident during the proposed Actions are not
significantly increased as the Actions require verification that the
CRE occupants are protected by the required mitigating actions.
Therefore, the proposed change does not involve a significant
increase in the probability or consequences of an accident
previously evaluated.
Criterion 2: Does the Proposed Change Create the Possibility of
a New or Different Kind of Accident from any Previously Evaluated?
Response: No.
This revision will not impact the accident analysis. The changes
will not alter the requirements of the CRE ventilation system or its
function during accident conditions. No new or different accidents
result from performing the new surveillance or following the new
program. The changes do not involve a physical alteration of the
plant (i.e., no new or different type of equipment will be
installed) or a significant change in the methods governing normal
plant operation. The changes do not alter assumptions made in the
safety analysis. The proposed changes are consistent with the safety
analysis assumptions and current plant operating practice.
Therefore, the proposed amendment does not create the
possibility of a new or different kind of accident from any accident
previously evaluated.
Criterion 3: Does the Proposed Change Involve a Significant
Reduction in the Margin of Safety?
Response: No.
The proposed changes do not alter the manner in which safety
limits, limiting safety system settings or limiting conditions for
operation are determined. The safety analysis acceptance criteria
are not affected by these changes. The proposed changes will not
result in plant operation in a configuration outside the design
basis. Compensatory measures are required to be established in order
to maintain plant operation in a configuration that is within the
design basis. The proposed changes do not adversely affect systems
that respond to safely shutdown the plant and to maintain the plant
in a safe shutdown condition.
Therefore, the proposed amendment would not involve a
significant reduction in a margin of safety.
Based on the NRC staff's review of the licensee's analysis, the
NRC staff concludes that the proposed amendment presents no
significant hazards consideration under the standards set forth in
10 CFR 50.92(c) and, accordingly, a finding of ``no significant
hazards consideration'' is justified.
