Subject:
License Amendment Request to Relocate Component Lists for Primary Containment Isolation Valves from Technical Specifications Pursuant to 10 CFR 50.90, PSEG Nuclear LLC hereby requests a change to the Technical Specifications (TS) for Hope Creek Generating Station (HCGS).
The proposed change would remove valve component lists and references to the lists from the Technical Specifications (TS). The information contained in the deleted tables would be relocated to the HCGS Technical Requirements Manual (TRM).
The proposed change is consistent with Generic Letter 91-08, "Removal of Component Lists from Technical Specifications," which provides guidance for preparing license amendment requests to remove component lists from the TS. This request meets all conditions outlined in the Generic Letter. Additionally, the revision does not alter the requirements for component operability currently in the Technical Specifications. The Limiting Conditions for Operation (LCOs) and Surveillance Requirements will be retained in the revised Technical Specifications and the proposed change will not affect the meaning, application, and function of the current Technical Specification requirements for the components.
The approach for this revision is consistent with the Improved Standard Technical Specifications (STS) described in NUREG-1433, "Standard Technical Specifications, General Electric Plants (BWR/4)," and changes previously approved by the NRC for other licensees, including the Limerick Generating Station.

1.0 DESCRIPTION
This letter is a request to amend Operating License NPF-57 for Hope Creek Generating Station.
The proposed changes would remove valve component lists for primary containment isolation valves and references to the lists from the Technical Specifications (TS) and relocate the information to a Technical Requirements Manual (TRM), a licensee controlled document, in accordance with Generic Letter 91-08, "Removal of Component Lists from Technical Specifications" (Reference 1).
2.0 PROPOSED CHANGE
TS Table 3.6.3-1, "Primary Containment Isolation Valves," would be removed from the TS and relocated to the TRM. The following additional changes are proposed to support relocation of TS Table 3.6.3-1:
- 1. The TS Index will be revised to delete the reference to Table 3.6.3-1.
- 2. TS Definition 1.32, "Primary Containment Integrity," will be revised to state the exception to closure of primary containment penetrations in more general terms rather than making a specific reference to TS Table 3.6.3-1 by replacing the words "as provided in Table 3.6.3-1 of" with the words "for valves that are opened under administrative control as permitted by."
- 3. TS Table 3.3.2-1, "Isolation Actuation Instrumentation," will be revised to reflect the removal of Table 3.6.3-1 by deleting Note (d). Table Notations for TS Table 3.3.2-1 identifying valves closed by a particular trip signal will be relocated to the TRM.
- 4. SR 4.6.1.1.b will be revised to state the exception to closure of primary containment penetrations in more general terms rather than making a specific reference to TS Table 3.6.3-1 by replacing the words "as provided in Table 3.6.3-1 of' with the words "for valves that are opened under administrative control as permitted by."
- 5. LCO 3.6.1.2.b, "Primary Containment Leakage," will be revised to delete the references to Table 3.6.3-1. LCO 3.6.2.1.b will be reworded in its entirety for clarity regarding the exceptions to the combined leakage rate. The proposed wording is as follows:
LR-N06-0437 Attachment 1 Page 2 A combined leakage rate in accordance with the Primary Containment Leakage Rate Testing Program for all primary containment penetrations and all primary containment isolation valves that are subject to Type B and C tests, except for: main steam line isolation valves*, valves which form the boundary for the long-term seal of the feedwater lines, other valves which are hydrostatically tested, and those valves where an exemption to Appendix J of 10 CFR 50 has been granted.
- 6. LCOs 3.6.1.2.d and 3.6.1.2.e will be revised to delete the reference to TS Table 3.6.3-1.
- 7. TS Action 3.6.1.2.b will be revised to delete the references to Table 3.6.3-1.
Action 3.6.1.2.b will be reworded in its entirety for clarity regarding the exceptions to the combined leakage rate. The proposed wording is as follows:
The measured combined leakage rate exceeding the leakage rate specified in the Primary Containment Leakage Rate Testing Program for all primary containment penetrations and all primary containment isolation valves that are subject to Type B and C tests, except for: main steam line isolation valves*, valves which form the boundary for the long-term seal of the feedwater lines, valves which are hydrostatically tested, and those valves where an exemption to Appendix J of 10 CFR 50 has been granted, or
- 8. TS restoration Action 3.6.1.2.b will be revised to delete the references to Table 3.6.3-1. Restoration Action 3.6.1.2.b is being reworded in its entirety for clarity regarding the exceptions to the combined leakage rate. The proposed wording is as follows:
The combined leakage rate to be in accordance with the Primary Containment Leakage Rate Testing Program for all primary containment penetrations and all primary containment isolation valves that are subject to Type B and C tests, except for: main steam line isolation valves*, valves which form the boundary for the long-term seal of the feedwater lines, valves which are hydrostatically tested, and those valves where an exemption to Appendix J of 10 CFR 50 has been granted, and
- 9. SRs 4.6.1.2.g and 4.6.1.2.h will be revised to delete the reference to TS Table 3.6.3-1.
- 10. LCO 3.6.3, "Primary Containment Isolation Valves," will be revised as follows to delete the references to Table 3.6.3-1:
Each primary containment isolation valve and each reactor instrumentation line excess flow check valve shall be OPERABLE.
LR-N06-0437 Attachment 1 Page 3 11 .TS Actions 3.6.3.a and 3.6.3.b, and SRs 4.6.3.1, 4.6.3.2, 4.6.3.3, and 4.6.3.4 will be revised to delete the references to Table 3.6.3-1.
12.A note will be added to SR 4.6.3.4 stating "the reactor vessel head seal leak detection line (penetration J5C) excess flow check valve is not required to be tested pursuant to this requirement."
13.TS Bases section 3/4.3.2, "Isolation Actuation Instrumentation," will be revised to refer to the TRM for identification of valve groups actuated by isolation trip functions.
14.TS Bases section 3/4.6.3 will be revised to refer to the TRM for the list of primary containment isolation valves covered by LCO 3.6.3.
- 15. TS Bases section 3/4.6.3 will be revised to add a description of administrative controls to be used when opening a valve that was locked or sealed closed to satisfy LCO 3.6.3 Action requirements, consistent with the guidance in GL 91-08 and with NUREG-1433:
The ACTIONS are modified by a Note allowing isolation valves closed to satisfy ACTION requirements to be reopened on an intermittent basis under administrative controls. These controls consist of stationing a dedicated operator at the controls of the valve, who is in continuous communication with the control room. In this way, the penetration can be rapidly isolated when a need for primary containment isolation is indicated.
Marked up TS pages are provided in Attachment 2. Marked up TS Bases pages are provided in Attachment 3. These Bases pages are being submitted for information only and do not require issuance by the NRC.
3.0 BACKGROUND
In May 1991, the NRC issued Generic Letter 91-08 to provide guidance on removing component lists from TS. As an alternative to identifying components by their plant identification number in tables of TS components, specifications may be stated in general terms that describe the types of components to which the requirements apply.
The NRC staff concluded that the removal of component lists is acceptable because it does not alter existing TS requirements or those components to which they apply.
The removal of component lists from TS permits administrative control of changes to these lists without processing a license amendment, as is required to update TS component lists. Any change to component lists contained in plant procedures is subject to the requirements specified in the Administrative Controls Section of the TS on changes to plant procedures. Therefore, the change control provisions of the TS
LR-N06-0437 Attachment 1 Page 4 provide an adequate means to control changes to these component lists, when they have been incorporated into plant procedures, without including them in TS. to GL 91-08 identified specific issues to be addressed in a request to remove component lists:
A. Each TS should include an appropriate description of the scope of the components to which the TS requirements apply. Components that are defined by regulatory requirements or guidance need not be clarified further. However, the Bases Section of the TS should reference the applicable requirements or guidance.
B. If the removal of a component list results in the loss of notes that modify or provide an exception to the TS requirements, the specification should be revised to incorporate that modification or exception. The modification or exception should be stated in terms that identify any group of components by function rather than by plant identification number, if practical.
C. Licensees should confirm that the lists of components removed from the TS are located in appropriately controlled plant procedures. The list of components may be included in the next update of the FSAR. The Bases Section of individual specifications also may reference the plant procedures or other documents that identify each component list. The Bases Section for the containment isolation valve TS should be updated to describe the intent of opening valves under administrative control.
4.0 TECHNICAL ANALYSIS
The proposed change would remove TS Table 3.6.3-1, "Primary Containment Isolation Valves," the associated Notations for TS Table 3.3.2-1 identifying valves closed by a particular isolation trip signal, and any references thereto from the TS. The lists would be relocated to the TRM. Changes to the TRM will be reviewed pursuant to 10 CFR 50.59, and summaries of changes will be provided to the NRC in the periodic 10 CFR 50.59 report. Relocating the tables from the TS will eliminate the burden of processing license amendments when changes are made to the tables and will facilitate the more effective utilization of NRC and PSEG resources.
With regard to the specific items to be addressed in accordance with the guidance in to GL 91-08:
A. LCO 3.6.3 will apply to "each primary containment isolation valve." Operability requirements for the reactor building-to-suppression chamber vacuum breakers are stated separately in LCO 3.6.4.2. Therefore, removal of TS Table 3.6.3-1, the associated Notations to Table 3.3.2-1, and all references thereto does not affect the scope of components to which the TS requirements apply.
LR-N06-0437 Attachment 1 Page 5 B. The Notes to Table 3.6.3-1 will be incorporated as discussed below to preserve existing approved modifications or exceptions to the TS requirements:
- 1. Note 1 states that main steam isolation valve leakage is not added to 0.60 La allowable leakage. This represents an exemption to the requirements of Appendix J to 10 CFR 50 and is already incorporated into LCO 3.6.1.2.b.
- 2. Note 2 identifies valves sealed with a water seal from the HPCI and/or RCIC system to form the long-term seal boundary of the feedwater lines. Limits on the leakage rate for these valves are already incorporated into LCO 3.6.1.2.d.
- 3. Note 3 identifies valves subject to Type C gas testing and leakage limits for those valves. Limits on the combined leakage rate for these valves are already incorporated into LCO 3.6.1.2.b and TS 6.8.4.f.
- 4. Note 4 identifies valves subject to Type C water testing and leakage limits for those valves. Limits on the combined leakage rate for these valves are already incorporated into LCO 3.6.1.2.e.
- 5. Note 5 identifies RHR and core spray system thermal relief valves that form part of the containment boundary. Leakage through these valves is determined during the overall integrated (Type A) test in accordance with the Primary Containment Leakage Rate Testing Program. This represents an exemption to the requirements of Appendix J to 10 CFR 50 and is incorporated into the proposed rewording of LCO 3.6.1.2.b.
- 6. Note 6 identifies drywell and suppression chamber pressure and level instrument root valves and excess flow check valves which are leakage tested during the Type A test. This represents an exemption to the requirements of Appendix J to 10 CFR 50 and is incorporated into the proposed rewording of LCO 3.6.1.2.b.
- 7. Note 7 states that explosive shear valves (SE-V021 through SE-V025) are not Type C tested. This represents an exemption to the requirements of Appendix J to 10 CFR 50 and is incorporated into the proposed rewording of LCO 3.6.1.2.b.
- 8. Note 8 states that surveillances for valves in the containment purge supply and exhaust lines are to be performed per Specification 3.6.1.8. SR 4.6.1.8.2 states that the containment purge supply and exhaust valves shall be demonstrated OPERABLE in accordance with the Primary Containment Leakage Rate Testing Program. Note 8 does not modify or provide an exception to the TS requirements and need not be incorporated into the TS.
LR-N06-0437 Attachment 1 Page 6
- 9. Note 9 describes the numbering convention for valves. It does not modify or provide an exception to the TS requirements and need not be incorporated into the TS.
- 10. Note 10 states that the reactor vessel head seal leak detection line (penetration J5C) excess flow check valve (BB-XV-3649) is not subject to OPERABILITY testing. A note will be added to SR 4.6.3.4 to preserve this existing approved modification to the TS requirements.
- 11. Note 11 identifies containment isolation valves that are not Type C tested because the lines penetrating the containment terminate below the minimum water level in the suppression chamber and the systems are closed systems outside Primary Containment. As noted in Reference 2, leak rate testing these valves is not required to satisfy Appendix J requirements for Type C testing. The proposed changes to LCO 3.6.1.2.b, TS Action 3.6.1.2.b and TS restoration Action 3.6.1.2.b make it clear that the leakage rate requirements do not apply to valves that are not subject to Type B and C tests. Note 11 does not modify or provide an exception to the TS requirements and need not be incorporated into the TS.
Note (d) to TS Table 3.3.2-1, "Isolation Actuation Instrumentation," will be deleted to reflect the removal of Table 3.6.3-1 and the Table Notations for TS Table 3.3.2-1 identifying valves closed by a particular trip signal will be relocated to the TRM. Note (d) and the Table Notations provide system design information. The proposed change does not affect the TS requirements for the isolation actuation trip functions listed in TS Table 3.3.2-1 and is consistent NUREG-1433, "Standard Technical Specifications, General Electric Plants (BWR/4)," which does not list the valve actuation groups in STS Table 3.3.6.1-1, "Primary Containment Isolation Instrumentation," or STS Table 3.3.6.2-1, "Secondary Containment Isolation Instrumentation."
C. Before implementing the proposed changes, PSEG will confirm that the list of CIVs is located in the Technical Requirements Manual, which will be an appropriately controlled plant procedure.
The proposed changes to TS Tables 3.3.2-1 and 3.6.3-1, "Primary Containment Isolation Valves," and the associated Notations for TS Table are administrative in that they merely relocate the CIV Tables from the TS to the TRM and maintain the requirements for CIV testing and the acceptance criteria for the testing in the Limiting Condition for Operation 3.6.3. Equipment test methods, frequencies, and acceptance criteria are not affected by the proposed changes.
The proposed changes are consistent with NUREG-1433, "Standard Technical Specifications, General Electric Plants (BWR/4)," which does not contain a list of CIVs.
LR-N06-0437 Attachment 1 Page 7 The list of CIVs is not included in STS section 3.6.1.3, "Primary Containment Isolation Valves (PCIVs)."
Relocating Table 3.6.3-1 from the TS to the TRM does not affect the TS requirements for CIVs or the components to which they apply. Changes to the TRM will be controlled in accordance with 10 CFR 50.59.
The proposed change is consistent with TS changes previously approved by the NRC for the Limerick Generating Station (Reference 3).
5.0 REGULATORY ANALYSIS
5.1 No Significant Hazards Consideration PSEG has evaluated whether or not a significant hazards consideration is involved with the proposed amendment(s) by focusing on the three standards set forth in 10 CFR 50.92, "Issuance of amendment," as discussed below:
- 1. Does the proposed amendment involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No.
The proposed relocation of Technical Specification component lists of primary containment isolation valves does not alter the requirements for component operability or surveillance currently in the Technical Specifications. The proposed change to remove the component lists from TS and relocate the information to an administratively controlled document will have no impact on any safety related structures, systems or components.
The probability of occurrence of a previously evaluated accident is not increased because this change does not introduce any new potential accident initiating conditions. The consequences of accidents previously evaluated in the UFSAR are not affected because the ability of the components to perform their required function is not affected.
Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2. Does the proposed amendment create the possibility of a new or different kind of accident from any accident previously evaluated?
Response: No.
LR-N06-0437 Attachment 1 Page 8 The proposed changes are administrative in nature, conform to the guidance in Generic Letter 91-08 and do not result in physical alterations or changes in the method by which any safety related system performs its intended function. The proposed changes do not affect any safety analysis assumptions. The proposed changes do not create any new accident initiators or involve an activity that could be an initiator of an accident of a different type.
All components will continue to be tested to the same requirements as defined in the Technical Specification Surveillance Requirements. The proposed revision does not make changes in any method of testing or how any safety related system performs its safety functions.
Therefore, the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.
- 3. Does the proposed amendment involve a significant reduction in a margin of safety?
Response: No.
The proposed change to remove Technical Specification Table 3.6.3-1 from the Technical Specifications and relocate it to the Technical Requirements Manual does not alter the Technical Specification requirements for containment integrity and containment isolation and will not affect the containment isolation capability. Future revisions to the Technical Requirements Manual Table will be subject to evaluation pursuant to 10 CFR 50.59.
The proposed change will not affect the current Technical Specification requirements or the components to which they apply.
Therefore, the proposed change does not involve a significant reduction in a margin of safety.
Based on the above, PSEG 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.
5.2 Applicable Regulatory Requirements/Criteria 10 CFR 50.36 specifies the criteria for including limiting conditions for operation (LCOs) in the TSs for commercial nuclear power reactors. According to 10 CFR
LR-N06-0437 Attachment 1 Page 9 50.36, an LCO must be established for items that meet one or more of the following criteria:
Criterion 1: Installed instrumentation that is used to detect, and indicate in the control room, a significant degradation of the reactor coolant pressure boundary.
Criterion 2: A process variable, design feature, or operating restriction that is an initial condition of a design basis accident or transient analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier.
Criterion 3: A structure, system, or component that is part of the primary success path and which functions or actuates to mitigate a design basis accident or transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier.
Criterion 4: A structure, system, or component which operating experience or probabilistic risk assessment has shown to be significant to public health and safety.
On May 6, 1991, the NRC issued Generic Letter (GL) 91-08, "Removal of Component Lists from Technical Specifications," which stated that the removal of component lists is acceptable because it does not alter existing TS requirements or those components to which they apply. The GL contains guidance on removing component lists from plant TSs and relocating them to other licensee-controlled documents.
In June 2004, the NRC issued Revision 3 to NUREG-1433, "Standard Technical Specifications, General Electric Plants (BWR/4)." Removal of the TS component tables described above is consistent with NUREG-1433.
In conclusion, based on the considerations discussed above, (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 amendment will not be inimical to the common defense and security or to the health and safety of the public.
6.0 ENVIRONMENTAL CONSIDERATION
A review has determined that the proposed amendment would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement. However, the proposed amendment does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the
LR-N06-0437 Attachment 1 Page 10 amounts of any effluent that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed amendment 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 amendment.

The hydrogen water chemistry (HWC) system shall not be placed in service until reactor power reaches 20% of RATED THERMAL POWER.
After reaching 20% of RATED THERMAL POWER, and prior to operating the HWC system, the normal full power background radiation level and associated trip setpoints may be increased to levels previously measured during full power operation with hydrogen injection. Prior to decreasing below 20% of RATED THERMAL POWER and after the HWC system has been shutoff, the background level and associated setpoint shall be returned to the normal full power values. If a power reduction event occurs so that the reactor power is below 20% of RATED THERMAL POWER without the required setpoint change, control rod motion shall be suspended (except for scram or other emergency actions) until the necessary setpoint adjustment is made.

The OPERABILITY of the isolation actuation instrumentation is dependent on the OPERABILITY of the -individual instrumentation channel Functions specified in Table 3.3.2-1.

The Main Steam Line Pressure - Low Function is directly assumed in the analysis of the pressure regulator failure (Ref. 2). For this event, the closure of the MSIVs ensures that the RPV temperature change limit (100 0 F/hr) is not reached.
The MSL low pressure signals are initiated from four transmitters that are connected to the MSL header. Four channels of Main Steam Line Pressure -

If the st am were allowed to continue flowing out of the break, the reactor would depr surize and the core could uncover, If the RPV water level decreases too fa , fuel damage could occur..
Therefore, the isolation is initiated on high flo to prevent or minimize core damage. The Main Steam Line Flow - High Func ion is directly assumed in the analysis of the main steam line break (MSLB) ( ef. 1). The isolation action, along with the scram function of the Reacto Protection System (RPS),

CONTAINMENT SYSTEMS BASES 3/4.6.3 PRIMARY CONTAINMENT ISOLATION VALVES The OPERABILITY of the primary containment isolation valves ensures that the containment atmosphere will be isolated from the outside environment in the event of a release of radioactive material to the containment atmosphere or pressurization of the containment and is consistent with the requirements of GDC 54 through 57 of Appendix A of 10 CFR 50. Containment isolation within the time limits specified for those isolation valves designed to close automatically. ensures that the release of radioactive material to the environment will be consistent with the assumptions used in the analyses for a LOCA. 'I--0s KTI Surveillance 4.6.3.4 requires demonstration that a representative sample of reactor instrumentation line excess flow check valves are tested to demonstrate'that the valve actuates to check flow on a simulated instrument line break. This surveillance requirement provides assurance that the instrument line EFCV's will perform so that the predicted radiological consequences will not be exceeded during a postulated instrument line break event as evaluated in the UFSAR. The 18-month frequency is based on the need to perform this surveillance under the conditions that apply immediately prior to and during the plant outage and the potential for an unplanned transient if the surveillance were performed with the reactor at power. The representative sample consists of an approximately equal number of EFCV's, such that each EFCV is tested at least once every ten years (nominal). In addition, the EFCV's in the sample are representative of the various plant configurations, models, sizes and operating environments. This ensures that any potentially common problem with a specific type or application of EFCV is detected at the earliest possible time. The nominal 10 year interval is based on performance testing as discussed in NEDO 32977-A, "Excess Check Valve Testing Relaxation."
Furthermore, any EFCV failures will be evaluated to determine if additional testing in that test interval is warranted to ensure overall reliability is maintained. Operating experience has demonstrated that these components are highly reliable and that, failures to isolate are very infrequent. Therefore, testing of a representative sample was concluded to be acceptable from a reliability standpoint.
3/4.6.4 VACUUM RELIEF Suppression Chamber-to-Drywell Vacuum Breakers BACKGROUND; The function of the suppression-chamber-to-drywell vacuum breakers is to relieve vacuum in the drywell. There are eight internal vacuum breakers located on the vent header of the vent system between the drywell and the suppression chamber that allow air and steam flow from the suppression chamber to the drywell when the drywell is at a negative pressure with respect to the suppression chamber. Therefore, suppression chamber-to-drywell vacuum breakers prevent an excessive negative differential pressure across the wetwell-drywell boundary. Each vacuum breaker is a self-actuating valve, similar to a check valve, which can be remotely operated for testing purposes.
