8. | Requested NRC Marked-up changes to CTS pages for several LCOs in ITS section 3.9, Question Refueling Operations, refer to same CTS LCO Condition instead of specifying the affected ITS LCO Condition. For example, a side note for CTS LCO Conditions 3.8.a.1a and b, (pl. refer to Attachment 1, Volume 14, Rev 0, Page 5 of 175), states, see CTS 3.8.a.1 and 3.8.a.8. The side note should have specified the affected ITS LCO Condition to which the CTS LCO Conditions 3.8.a.1a&b are relocated/converted. This concern also applies to side notes on the same page (page 5) for CTS LCO Conditions 3.8.a.2, 3.8.a.3, and note 1 (bottom of CTS page 3.8-1). Please note that marked changes on page 5 are also repeated on pages 25, 26, 27, 48, 49, 94, 95, 111, 112, 119, 126, 132, 139, and 147. | ||

KPS proposes to replace the statement with insert 1 on Page 16. However, the proposed insert does not specify a plant specific system for maintaining the boron concentration. KPS USAR section 1.3.5, Reactivity Control (GDC 27 - GDC 32), states, In addition to the reactivity control achieved by the RCC assemblies (RCCA) as detailed in Chapter 7, reactivity control is provided by the Chemical and Volume Control System which regulates the concentration of boric acid solution neutron absorber in the Reactor Coolant System. | |||

3/2/2010 10:50 AM Date/Time Closure Statement | |||
===Response=== | |||
Statement While the quoted information from USAR section 1.3.5 is correct, it is not the current and licensed requirement; it is the original FSAR requirement. | |||
Specifically, on the first page of Section 1.3, a Note at the front of the Section states: | |||
"NOTE: Section 1.3 provides original licensing and design basis information for the Kewaunee Plant as described in the facility license application Amendment No. 7 (the FSAR), dated January 27, 1971, and subsequent Amendments 8 through 20; and approved in the AEC Safety Evaluation issued July 24, 1972, and its supplements. This information was developed in support of plant licensing; therefore, this section is considered historical and should not be revised. Updated information can be found in the applicable section of the USAR." | |||
For KPS GDC 27, this is found in USAR Section 3.1.2.3, as shown in the Reference Section of the ITS 3.9.1 Bases (Page 19). USAR Section 3.1.2.3 states as the Criterion: "Two independent reactivity control systems, preferably of different principles, shall be provided (GDC 27)." These are the words KPS inserted in lieu of the ISTS wording for 10 CFR 50, Appendix A, GDC 26. | |||
KPS further noted that the ISTS wording stated that there were two independent reactivity control systems, but only one potential system, the Chemical and Volume Control System (CVCS), is identified in the paragraph. The main reactivity control system that is specified in the Technical Specifications, i.e., control rods, is not in the paragraph. KPS also reviewed the wording of 10 CFR 50, Appendix A, GDC 56 and noted that the ISTS wording does not match the GDC being referenced. The words in 10 CFR 50, Appendix A are: | |||
"Criterion 26--Reactivity control system redundancy and capability. Two independent reactivity control systems of different design principles shall be provided. One of the systems shall use control rods, preferably including a positive means for inserting the rods, and shall be capable of reliably controlling reactivity changes to assure that under conditions of normal operation, including anticipated operational occurrences, and with appropriate margin for malfunctions such as stuck rods, specified Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 7 of 208 http://www.excelservices.com/rai/index.php?requestType=areaItemPrint&itemId=2371 06/07/2010 | |||
Kewaunee ITS Conversion Database Page 2 of 2 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 8 of 208 acceptable fuel design limits are not exceeded. The second reactivity control system shall be capable of reliably controlling the rate of reactivity changes resulting from planned, normal power changes (including xenon burnout) to assure acceptable fuel design limits are not exceeded. One of the systems shall be capable of holding the reactor core subcritical under cold conditions." | |||
None of the words in 10 CFR 50, Appendix A use the CVCS by name. | |||
Furthermore, the CVCS was deleted from the Technical Specifications and allowed to be placed in a document under utility control when the ISTS was originally issued. Thus, adding the name of a non-Technical Specification System into the Applicable Safety Analyses Bases could imply that the System needs to be in the Technical Specification. | |||
Therefore, KPS does not believe that the CVCS should be mentioned in the Bases paragraph, and that the proposed words in the KPS submittal are correct and should be maintained as is. | |||

Requested NRC Question Attachment 1, Volume 14, Rev. 0, Page 58 of 175 proposed ITS LCO 3.9.3, Residual Heat Removal (RHR) and Coolant Circulation - High Water Level Proposed change deletes logical connector OR between Required Actions A.6.1 and A.6.2. Justification For Deviations (JFD) note 3 on page 59 states, ISTS 3.9.5 Required Actions A.6.1 and A.6.2 are connected by an "OR" logical connector, such that either one can be performed to meet the requirements of the ACTION. However, the two Required Actions are applicable to all the penetrations; either Required Action A.6.1 or Required Action A.6.2 must be performed for all the penetrations. Thus, this will not allow one penetration to be isolated by use of a manual valve and another penetration to be capable of being closed by an OPERABLE Containment Purge and Exhaust Isolation System. This is not the intent of the requirement. The requirement is based on ISTS LCO 3.9.4, which requires each penetration to be either: a) closed by a manual or automatic isolation valve, blind flange, or equivalent; or b) capable of being closed by an OPERABLE Containment Purge and Exhaust Isolation System. For consistency with the actual LCO requirement, ISTS 3.9.5 Required Actions A.6.1 and A.6.2 have been combined into a single Required Action in ITS 3.9.3 Required Action A.6. | |||
Logical connectors are used in Technical Specifications (TS) to discriminate between, and yet connect, discrete Conditions, Required Actions, Completion Times, Surveillances, and Frequencies. The only logical connectors that appear in Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 10 of 208 http://www.excelservices.com/rai/index.php?requestType=areaItemPrint&itemId=1791 06/07/2010 | |||
Kewaunee ITS Conversion Database Page 2 of 2 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 11 of 208 TS are AND and OR. The physical arrangement of these connectors constitutes logical conventions with specific meanings. Required Actions A.6.1 and A.6.2 as specified in the TS, must be taken when the plant is in Condition A. These Actions as well as Completion Times for the Actions are not bracketed, and therefore plant specific changes are not acceptable. Revise the proposed ITS to incorporate the Required Actions and completion times of A.6.1 and A.6.2 per NUREG-1431, Revision 3. . | |||

3/8/2010 10:20 AM Date/Time Closure Statement | |||
===Response=== | |||
Statement The purpose of ISTS 3.9.5 Required Actions A.4, A.5, A.6.1 and A.6.2, as stated in the ISTS Bases, is to ensure that all containment penetrations are either closed or can be closed so that the dose limits are not exceeded when the RHR loop requirements are not met. These actions come directly from the requirements of ISTS 3.9.3. With respect to the penetrations providing direct access from the containment atmosphere to the outside atmosphere, ISTS LCO 3.9.3.c (shown on Page 164 of Volume 14) requires that for each penetration, either it must be capable of being closed by a manual or automatic isolation valve, blind flange, or equivalent, or it must be capable of being closed by an OPERABLE Containment Purge and Exhaust Isolation System. Thus, ISTS LCO 3.9.3 allows either option for each of the penetrations; a single option does not have to be used for all of the penetrations. | |||
ISTS 3.9.5 Required Actions A.6.1 and A.6.2 are written such that only one of these can be used for every single penetration. Either you have to meet Required Action A.6.1 for all the penetrations or you have to meet Required Action A.6.2 for all the penetrations. Obviously, a plant cannot meet Required Action A.6.2 for all the penetrations, since they all do not have automatic closure capability. The true intent of these two Required Actions is as stated in the ISTS Bases. The ISTS Bases for these two Required Actions (Page 64) are in the same paragraph and describes that each penetration must be closed by a manual or automatic isolation valve, blind flange, or equivalent, or verified to be capable of being closed by and OPERABLE Containment Purge and Exhaust Isolation System. Thus, for each penetration, you chose Required Action A.6.1 or A.6.2. | |||
KPS has made a change to reflect what the requirements are in both ISTS LCO 3.9.3 and ISTS 3.9.5 Required Actions A.6.1 and A.6.2 Bases. | |||
Adopting the ISTS 3.9.5 Required Actions A.6.1 and A.6.2 as written, without combining the two in a single Required Action, would force KPS to essentially use ISTS 3.9.5 Required Action A.6.1 at all times (since not all penetrations are capable of being closed by an automatic isolation system). This change has been previously reviewed and approved by the NRC during recent ITS conversions, like DC Cook Units 1 and 2 and Davis-Besse. Therefore, KPS believes that this change is only an editorial change to correct an inconsistency with the base requirement in ISTS Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 12 of 208 http://www.excelservices.com/rai/index.php?requestType=areaItemPrint&itemId=2481 06/07/2010 | |||

3/10/2010 7:05 AM Date/Time Closure Statement | |||
===Response=== | |||
Statement The Kewaunee Power Station (KPS) CTS does not include any shutdown cooling minimum flow rate requirements while in MODE 6. KPS added SR 3.9.3.1 (and SR 3.9.4.1) as part of the ITS conversion. However, the minimum flow rate value was not included, as is stated in JFD 5. The JFD states that "The ISTS Bases states that the flow rate is determined by the flow rate necessary to provide sufficient decay heat removal capability. | |||
However, the decay heat is not always the same; it is a function of time after shutdown and the power history of the fuel." Thus, there is no single value of shutdown cooling flow that will ensure decay heat is removed under all conditions. The JFD further states "Furthermore, SRs in Section 3.4 (ITS SRs 3.4.6.1, 3.4.7.1, and 3.4.8.1) require a similar verification that the RHR loop is in operation, but do not specify a flow rate requirement." In addition, KPS does not have RHR flow indication that could quantify the flow through the RHR heat exchanger (which is the flow removing the decay heat). The RHR flow meter is downstream of the connection where the heat exchanger discharge flow and heat exchanger bypass flow is merged. When in the shutdown cooling mode, some of the flow is going through the heat exchanger and some of the flow is bypassing the heat exchanger. Flow through the bypass is throttled to obtain the flow necessary to maintain RCS temperature at the desired value. However, the actual flow through the heat exchanger is not known, only the total RHR flow is known. USAR Figure 9.3-1, on page 9.3-27, provides a drawing of the RHR System (FT 626 is the flow instrument) | |||
KPS believes that including a Surveillance to verify one RHR loop is in operation and circulating reactor coolant is sufficient to ensure the surveillance criteria of 10 CFR 50.36(c)(3) are met. Specifically, 10 CFR 50.36(c)(3) states that "Surveillance requirements are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met." SR 3.9.3.1 continues to ensure that this requirement is met, since there is no specific flow value in any safety limit. LCO 3.9.3 is required to ensure temperature is maintained to prevent boiling (as stated in the ASA section of the ISTS Bases), and this is met by having one RHR loop in operation and circulating coolant. | |||

===Response=== | |||
Statement KPS does not include the RHR flowrate in the KPS ITS SRs similar to several similar vintage PWRs (Point Beach, Prairie Island, and R.E. Ginna) which all have ITS. KPS does not have a specific analysis for boron and thermal stratification. | |||
The Kewaunee Power Station reviewed boron and thermal stratification industry standards that were considered in the development of NUREG-1431. | |||
As an industry, the fact that by license, RHR flow is maintained to the Reactor Coolant System while shutdown precludes that possibility of stratification. The one hour exception in the ISTS LCO 3.9.5 Note (KPS ITS LCO 3.9.3 Note) allows for stable water conditions during movement of components such as reactor internals. This is an accepted industry practice and an allowance already approved by the NRC. The ISTS Bases description of the Note does not discuss thermal stratification issues. It only provides compensatory measures to preclude boron concentration reduction during this 1 hour period. | |||
Thermal and boron stratification do not occur with forced circulation as required by ITS. During MODE 6, temperatures are maintained well below boiling in the core with the water level above the core and temperature of the coolant at <140°F by procedure in the refueling cavity. Temperatures encountered in MODE 6 do not present a safety issue from thermal stratification since it is common industry practice to secure RHR for short periods of time. CTS requires RHR pumps to be OPERABLE, but does not specify a flow requirement. | |||
Boron stratification is not a concern due to the fact that boron is soluble well above refueling concentrations that could possibly cause blockage of flow channels. WCAP 1570 solubility curves in water show that at 0 ºC boron is soluble to ~4800 ppm and at 20ºC boron is soluble to ~8000 ppm. | |||
Also, when in MODE 6 with boron concentration within the limits of LCO 3.9.1, the possibility of a reactivity event is extremely remote. Diffusion of boron follows the rules of diffusion theory, thus there is low probability of varying concentrations of boron in the reactor coolant without flow. | |||
Stratification is more of a post accident situation with a loss of coolant Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 20 of 208 http://www.excelservices.com/rai/index.php?requestType=areaItemPrint&itemId=2681 06/07/2010 | |||

Therefore KPs considers that industry PWR design precludes thermal and boron stratification in MODE 6. | |||

Requested NRC Question Attachment 1, Volume 14, Rev. 0, Pages 89,164,166 of 175 proposed ISTS Section 3.9.4, Containment Penetrations KPS Proposed changes: | |||
(a) ISTS LCO 3.9.4, addresses specific requirements for the containment penetrations status during movement of | |||
[recently] irradiated fuel assemblies within containment. On page 166, KPS states that no credit is taken for the containment penetrations in the fuel handling accident analysis at KPS and since the Applicability of ISTS 3.9.4 is during movement of recently irradiated fuel assemblies within containment, the subject LCO is not included in KPS ITS. | |||
(b) On page 127, KPS states, CTS 3.8.a.3 requires the reactor to be subcritical for 148 hours prior to movement of its irradiated fuel assemblies. The ITS does not include this requirement. This changes the CTS by moving the explicit decay time requirement from the Technical Specifications to Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 23 of 208 http://www.excelservices.com/rai/index.php?requestType=areaItemPrint&itemId=2151 06/22/2010 | |||
Kewaunee ITS Conversion Database Page 2 of 2 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 24 of 208 the Technical Requirements Manual (TRM). This change is designated as a less restrictive removal of detail change because a requirement is being removed from the Technical Specifications. Whereas, marked-up changes on page 102 of KPS ITS Bases B 3.9.7 (KPS B 3.9.5) show that KPS intends to keep the minimum decay time which is marked-up as 100 hours, in the Bases. | |||
Discussion: | |||
As stated in the ITS Bases, fuel handling accidents, analyzed in Reference 3, include dropping a single irradiated fuel assembly and handling tool or a heavy object onto other irradiated fuel assemblies. The requirements of LCO 3.9.7, "Refueling Cavity Water Level," in conjunction with a minimum decay time of 100 hours prior to [irradiated fuel movement with containment closure capability or a minimum decay time of [x] | |||
days without containment closure capability], ensures that the release of fission product radioactivity, subsequent to a fuel handling accident, results in doses that are well within the guideline values specified in 10 CFR 100. | |||
Based on the above, please retain ITS LCO 3.9.4 for KPS ITS and specify of minimum decay time requirement in KPS ITS Bases to ensure the staff can conclude KPS TS ensure adequate protection of the public health and safety. | |||

Add proposed SR 3.9.6.1 M01 Amendment No. 200 TS 3.8-2 11/20/2008 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 30 of 208 Page 2 of 2 | |||
Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 31 of 208 DISCUSSION OF CHANGES ITS 3.9.6, CONTAINMENT PENETRATIONS ADMINISTRATIVE CHANGES A01 In the conversion of the Kewaunee Power Station (KPS) Current Technical Specifications (CTS) to the plant specific Improved Technical Specifications (ITS), certain changes (wording preferences, editorial changes, reformatting, revised numbering, etc.) are made to obtain consistency with NUREG-1431, Rev. 3.0, "Standard Technical Specifications-Westinghouse Plants" (ISTS). | |||
These changes are designated as administrative changes and are acceptable because they do not result in technical changes to the CTS. | |||
A02 When the containment penetrations are not in the required condition specified in CTS 3.8.a.1 or CTS 3.8.a.8, CTS 3.8.b requires refueling of the reactor to cease, initiation of action to restore the containment penetrations to the required conditions, and no operations be performed that could increase the reactivity of the core. Under similar conditions, ITS 3.9.6 ACTION A only requires movement of irradiated fuel assemblies within containment to be suspended. This changes the CTS by deleting the requirements to initiate action to restore the containment penetrations to the required conditions and that no operations be performed that could increase the reactivity of the core. | |||
The purpose of CTS 3.8.a.8 is to ensure proper compensatory actions are taken to exit the Applicability of the LCO. CTS 3.8.a.1 and 3.8.a.8 are only applicable during REFUELING OPERATIONS, which is defined in CTS Section 1.0 as the movement of reactor vessel internals that could affect the reactivity of the core within the containment when the vessel head is unbolted or removed. Thus, after the first requirement of CTS 3.8.b is met (i.e., suspend refueling the reactor), the Applicability has been exited and thus, continuation of the requirements of CTS 3.8.b are not required. Therefore, this change is acceptable and is designated as administrative since the technical requirements have not been changed. | |||
MORE RESTRICTIVE CHANGES M01 CTS 3.8.a does not provide a Surveillance Requirement to verify each required containment penetration is in the required status. The ITS adds a Surveillance Requirement (SR 3.9.6.1) to verify each required containment penetration is in the required status once every 7 days. This changes the CTS by adding a new Surveillance Requirement for the containment penetrations. | |||
This change is acceptable because the added Surveillance Requirement ensures that each required containment penetration is in the required status to support the containment penetration conditions assumed in the Fuel Handling Accident (FHA) analysis. In addition, this change is acceptable because the Surveillance Requirement continues to ensure that the structures, systems, and components are maintained consistent with the safety analyses and licensing basis. This change is designated as more restrictive because a new Surveillance Requirement has been added. | |||

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 32 of 208 DISCUSSION OF CHANGES ITS 3.9.6, CONTAINMENT PENETRATIONS RELOCATED SPECIFICATIONS None REMOVED DETAIL CHANGES LA01 (Type 3 - Removing Procedural Details for Meeting TS Requirements or Reporting Requirements) CTS 3.8.a.1.a requires at least one door in each personnel air lock to be capable of being closed "within 30 minutes." | |||
- | CTS 3.8.a.1.a is modified by a footnote (1) that states "Administrative controls ensure that appropriate personnel are aware that both personnel air lock doors are open; a specified individual(s) is designated and available to close the air lock following a required evacuation of containment; and, any obstruction(s) (e.g., | ||
cables and hoses) that could prevent closure of an open air lock can be quickly removed." ITS 3.9.6 does not contain this footnote information or the 30 minute requirement. This changes the CTS by moving the information contained in the footnote and the 30 minute requirement to the Bases. | |||
The removal of these details, which are related to procedural details for meeting Technical Specification requirements, from the Technical Specifications is acceptable because this type of information is not necessary to be included in the Technical Specifications to provide adequate protection of public health and safety. The ITS still retains the requirement for at least one door in each personnel air lock to be capable of being closed. Also, this change is acceptable because the removed information will be adequately controlled in the ITS Bases. | |||
Changes to the Bases are controlled by the Technical Specification Bases Control Program in Chapter 5. This program provides for the evaluation of changes to ensure the Bases are properly controlled. This change is designated as a less restrictive removal of detail change because information relating to procedural details for meeting Technical Specification requirements is being removed from the Technical Specifications. | |||
LESS RESTRICTIVE CHANGES L01 (Category 1 - Relaxation of LCO Requirements) CTS 3.8.a.1.a, in part, requires at least one door in each personnel air lock to be closed when the reactor vessel head or upper internals are being lifted. ITS 3.9.6 does not include this requirement. This changes the CTS by not requiring one door in each personnel air lock to be closed when the reactor vessel head or upper internals are being lifted. | |||
The purpose of CTS 3.8.a.1 is to ensure that if a fuel handling accident occurs, the release of any subsequent fission products results in doses that are well within the guideline values specified in Regulatory Guide 1.183. A fuel handling accident, as analyzed in USAR Section 14.2.1, is postulated to occur during handling of irradiated fuel assemblies; not handling the vessel head or upper internals. Thus, moving the vessel head or upper internals cannot result in a fuel handling accident. Any additional requirements, above those required to meet the assumptions of the fuel handling accident, are more appropriately controlled Kewaunee Power Station Page 2 of 5 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 32 of 208 | |||
Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 33 of 208 DISCUSSION OF CHANGES ITS 3.9.6, CONTAINMENT PENETRATIONS by plant procedures. Therefore, this change is acceptable and is designated a less restrictive change since the requirement to maintain containment closure capability during movement of the vessel head or upper internals is being deleted from the CTS. | |||
L02 (Category 1 - Relaxation of LCO Requirements) CTS 3.8.a.1.b, in part, states that each line that penetrates containment and which provides a direct air path from containment atmosphere to the outside atmosphere shall have a closed isolation valve. ITS LCO 3.9.6.c.1 states that each penetration providing direct access from the containment atmosphere to the outside atmosphere is closed by a manual or automatic isolation valve, blind flange, or equivalent. This changes the CTS by specifying the use of a blind flange or an equivalent means of isolating a containment penetration. | |||
The purpose of CTS 3.8.a.1 is to ensure the containment penetrations are in the condition assumed in the Fuel Handling Accident (FHA) analysis. This change is acceptable because the LCO requirements continue to ensure that the structures, systems, and components are maintained consistent with the safety analyses and licensing basis. The addition of the option to use a blind flange or some other equivalent means of isolating the containment penetration allows additional flexibility in the ITS that was not available in CTS. This change is designated as less restrictive because less stringent LCO requirements are being applied in the ITS than were applied in the CTS. | |||
L03 (Category 1 - Relaxation of LCO Requirements) ITS LCO 3.9.6 Note states "Penetration flow path(s), except the equipment hatch, providing direct access from the containment atmosphere to the outside atmosphere may be unisolated under administrative controls." CTS 3.8.a does not include such an allowance. | |||
This changes the CTS by allowing containment penetration flow paths to be unisolated under administrative controls during movement of irradiated fuel assemblies within containment. | |||
The purpose of CTS 3.8.a.1 is to ensure the containment penetrations are in the condition assumed in the Fuel Handling Accident (FHA) analysis. This change is acceptable because the LCO requirements continue to ensure that the structures, systems, and components are maintained consistent with the safety analyses and licensing basis. The Reviewers Note in the ISTS LCO Bases associated with the LCO Note states that the allowance to have the personnel air lock doors open and the penetration flow paths unisolated under administrative control requires confirmatory dose calculations approved by the NRC staff and commitments from the licensee to implement acceptable administrative procedures to ensure that in the event of a refueling accident that the open penetration(s) can and will be promptly closed. The confirmatory dose calculations were made by the NRC as part of Amendment 166, dated 3/17/2003 (ADAMS Accession No. ML030210062) as modified by Amendment 190, dated 3/8/2007 (ADAMS Accession No. ML070430020). These Amendments revised the radiological consequence analyses for the KPS FHA to implement the Alternate Source Term. Kewaunee Power Station commits to implementing administrative procedures to ensure that in the event of a refueling accident, the open air locks and open penetration(s) can and will be promptly closed.

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 34 of 208 DISCUSSION OF CHANGES ITS 3.9.6, CONTAINMENT PENETRATIONS change is designated as less restrictive because less stringent LCO requirements are being applied in the ITS than were applied in the CTS. | |||
L04 (Category 6 - Relaxation Of Surveillance Requirement Acceptance Criteria) | |||
CTS 3.8.a.8 requires verification of the automatic actuation of the Containment Ventilation and Purge valves on a containment ventilation isolation signal. ITS SR 3.9.6.2 specifies that the signal may be from either an actual or simulated signal. This changes the CTS by explicitly allowing the use of either an actual or simulated signal to perform the Surveillance. | |||
The purpose of CTS 3.8.a.8 is to ensure that the containment purge and vent valves operate correctly upon receipt of an actuation signal. This change is acceptable because it has been determined that the relaxed Surveillance Requirement acceptance criteria are not necessary for verification that the equipment used to meet the LCO can perform its required functions. Equipment cannot discriminate between an "actual," "simulated," or "test" signal and, therefore, the results of the testing are unaffected by the type of signal used to initiate the test. This change allows taking credit for unplanned actuation if sufficient information is collected to satisfy the Surveillance test requirements. | |||
The change also allows a simulated signal to be used, if necessary. This change is designated as less restrictive because less stringent Surveillance Requirements are being applied in the ITS than were applied in the CTS. | |||
L05 (Category 7 - Relaxation Of Surveillance Frequency) CTS 3.8.a.8 includes a Surveillance Frequency of "immediately prior to and daily during REFUELING OPERATIONS" for performing a Surveillance of the Containment Ventilation and Purge System. The ITS SR 3.9.6.2 Frequency for the same requirement is 18 months. ITS SR 3.9.6.2 is also modified by a Note that states that SR 3.9.6.2 is not required to be met for containment purge and vent valve(s) in penetrations that are closed to comply with LCO 3.9.6.c.1. This changes the CTS by changing the Surveillance Frequency from immediately prior to and daily during REFUELING OPERATIONS to 18 months and adding the Note that the SR is not required to be met for containment purge and vent valve(s) in penetrations that are closed to comply with ITS LCO 3.9.6.c.1. | |||
The purpose of CTS 3.8.a.8 is to verify the equipment required to meet the LCO is OPERABLE. This change is acceptable because the new Surveillance Frequency has been evaluated to ensure that it provides an acceptable level of equipment reliability. Containment purge and vent valve testing is still required, but at a Frequency consistent with the testing Frequency for containment isolation valves required in MODES 1, 2, 3, and 4. This Frequency provides an appropriate degree of assurance that the valves are OPERABLE. When containment purge and vent valve(s) in penetrations are closed to comply with ITS LCO 3.9.6.c.1, the penetrations are in the expected condition (isolated) to mitigate the effects of a fuel handling accident inside containment. Therefore, there is no need for the actuation signal to reposition the valves to the closed position. This change is designated as less restrictive because Surveillances will be performed less frequently under the ITS than under the CTS. | |||
L06 (Category 1 - Relaxation of LCO Requirements) CTS 3.8.a specifies that the CTS 3.8.a.1 containment closure requirements are applicable during Kewaunee Power Station Page 4 of 5 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 34 of 208 | |||
Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 35 of 208 DISCUSSION OF CHANGES ITS 3.9.6, CONTAINMENT PENETRATIONS REFUELING OPERATIONS, which is defined in CTS Section 1.0 as the movement of reactor vessel internals that could affect the reactivity of the core within the containment when the vessel head is unbolted or removed. ITS 3.9.6 is applicable during movement of irradiated fuel assemblies within containment. | |||
This changes the CTS by not requiring the containment closure requirements to be met when moving or handling control rods during MODE 6 operation. | |||
The purpose of CTS 3.8.a.1 is to ensure that if a fuel handling accident occurs, the release of any subsequent fission products results in doses that are well within the guideline values specified in Regulatory Guide 1.183. A fuel handling accident, as analyzed in USAR Section 14.2.1, can only occur during handling of irradiated fuel assemblies; not moving or handling control rods (which are the only other reactor vessel internals currently in use at KPS that could affect reactivity of the core). Thus, moving or handling the control rods cannot result in a fuel handling accident. Any additional requirements, above those required to meet the assumptions of the fuel handling accident, are more appropriately controlled by plant procedures. Therefore, this change is acceptable and is designated a less restrictive change since the requirement to maintain containment closure capability during movement or handling of control rods in MODE 6 is being deleted from the CTS. | |||

BASES BACKGROUND During movement of [recently] irradiated fuel assemblies within containment, a release of fission product radioactivity within containment will be restricted from escaping to the environment when the LCO requirements are met. In MODES 1, 2, 3, and 4, this is accomplished by maintaining containment OPERABLE as described in LCO 3.6.1, "Containment." In MODE 6, the potential for containment pressurization as a result of an accident is not likely; therefore, requirements to isolate the containment from the outside atmosphere can be less stringent. The LCO requirements are referred to as "containment closure" rather than "containment OPERABILITY." Containment closure means that all potential escape paths are closed or capable of being closed. Since there is no potential for containment pressurization, the Appendix J leakage criteria and tests are not required. | |||
The containment serves to contain fission product radioactivity that may be released from the reactor core following an accident, such that offsite radiation exposures are maintained well within the requirements of guidance 2 Regulatory Guide 1.183 (Ref. 1) 10 CFR 100. Additionally, the containment provides radiation shielding from the fission products that may be present in the containment atmosphere following accident conditions. | |||
3. | The containment equipment hatch, which is part of the containment pressure boundary, provides a means for moving large equipment and components into and out of containment. During movement of [recently] | ||
irradiated fuel assemblies within containment, the equipment hatch must be held in place by at least four bolts. Good engineering practice dictates that the bolts required by this LCO be approximately equally spaced. | |||
The containment air locks, which are also part of the containment pressure boundary, provide a means for personnel access during MODES 1, 2, 3, and 4 unit operation in accordance with LCO 3.6.2, "Containment Air Locks." Each air lock has a door at both ends. The doors are normally interlocked to prevent simultaneous opening when containment OPERABILITY is required. During periods of unit shutdown when containment closure is not required, the door interlock mechanism may be disabled, allowing both doors of an air lock to remain open for extended periods when frequent containment entry is necessary. | |||
During movement of [recently] irradiated fuel assemblies within containment, containment closure is required; therefore, the door interlock mechanism may remain disabled, but one air lock door must always remain [capable of being] closed. | |||

BASES TSTF-471-A APPLICABLE During CORE ALTERATIONS or movement of irradiated fuel assemblies SAFETY within containment, the most severe radiological consequences result ANALYSES from a fuel handling accident [involving handling recently irradiated fuel]. | |||
The fuel handling accident is a postulated event that involves damage to 2 irradiated fuel (Ref. 2). Fuel handling accidents, analyzed in Reference 3, 2 vertically onto a rigid surface or include dropping a single irradiated fuel assembly and handling tool or a heavy object onto other irradiated fuel assemblies. The requirements of 5 LCO 3.9.7, "Refueling Cavity Water Level," in conjunction with a minimum 7 decay time of 100 hours prior to [irradiated fuel movement with containment closure capability or a minimum decay time of [x] days Regulatory Guide 1.183 without containment closure capability], ensures that the release of fission (Ref. 1) product radioactivity, subsequent to a fuel handling accident, results in 2 | |||
doses that are well within the guideline values specified in 10 CFR 100. | |||
Standard Review Plan, Section 15.7.4, Rev. 1 (Ref. 3), defines "well within" 10 CFR 100 to be 25% or less of the 10 CFR 100 values. The 2 | |||
acceptance limits for offsite radiation exposure will be 25% of 10 CFR 100 values or the NRC staff approved licensing basis (e.g., a specified fraction of 10 CFR 100 limits). | |||
Containment penetrations satisfy Criterion 3 of 10 CFR 50.36(c)(2)(ii). | |||
LCO -----------------------------------REVIEWERS NOTE----------------------------------- | |||
The allowance to have containment personnel air lock doors open and TSTF-471-A penetration flow paths with direct access from the containment atmosphere to the outside atmosphere to be unisolated during fuel movement and CORE ALTERATIONS is based on (1) confirmatory dose calculations of a fuel handling accident as approved by the NRC staff which indicate acceptable radiological consequences and 3 (2) commitments from the licensee to implement acceptable administrative procedures that ensure in the event of a refueling accident (even though the containment fission product control function is not required to meet acceptable dose consequences) that the open air lock can and will be promptly closed following containment evacuation and that the open penetration(s) can and will be promptly closed. The time to close such penetrations or combination of penetrations shall be included in the confirmatory dose calculations. | |||
This LCO limits the consequences of a fuel handling accident [involving 2 handling recently irradiated fuel] in containment by limiting the potential escape paths for fission product radioactivity released within containment. | |||
The LCO requires any penetration providing direct access from the containment atmosphere to the outside atmosphere to be closed except for the OPERABLE containment purge and exhaust penetrations [and the 2 vent containment personnel air locks]. For the OPERABLE WOG STS B 3.9.4-3 Rev. 3.0, 03/31/04 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 44 of 208 | |||

The OPERABILITY requirements for this LCO ensure 2 that the automatic purge and exhaust valve closure times specified in the FSAR can be achieved and, therefore, meet the assumptions used in the safety analysis to ensure that releases through the valves are terminated, such that radiological doses are within the acceptance limit. | ||
, except the The LCO is modified by a Note allowing penetration flow paths with direct equipment 8 hatch, access from the containment atmosphere to the outside atmosphere to be unisolated under administrative controls. Administrative controls ensure that 1) appropriate personnel are aware of the open status of the TSTF-471-A penetration flow path during CORE ALTERATIONS or movement of irradiated fuel assemblies within containment, and 2) specified individuals are designated and readily available to isolate the flow path in the event 2 of a fuel handling accident. INSERT 2 may 4 | |||
within 30 minutes The containment personnel air lock doors many be open during movement of [recently] irradiated fuel in the containment provided that 1 one door is capable of being closed in the event of a fuel handling 2 INSERT 3 accident. Should a fuel handling accident occur inside containment, one 2 personnel air lock door will be closed following an evacuation of containment. | |||
APPLICABILITY The containment penetration requirements are applicable during 1 | |||
movement of [recently] irradiated fuel assemblies within containment because this is when there is a potential for the limiting fuel handling accident. In MODES 1, 2, 3, and 4, containment penetration requirements are addressed by LCO 3.6.1. In MODES 5 and 6, when movement of irradiated fuel assemblies within containment is not being conducted, the potential for a fuel handling accident does not exist. | |||
[Additionally, due to radioactive decay, a fuel handling accident involving handling recently irradiated fuel (i.e., fuel that has occupied part of a 1 critical reactor core within the previous [x] days) will result in doses that are well within the guideline values specified in 10 CFR 100 even without containment closure capability.] Therefore, under these conditions no requirements are placed on containment penetration status. | |||

-----------------------------------REVIEWERS NOTE----------------------------------- | |||
The addition of the term "recently" associated with handling irradiated fuel in all of the containment function Technical Specification requirements is only applicable to those licensees who have demonstrated by analysis that after sufficient radioactive decay has occurred, off-site doses resulting from a fuel handling accident remain below the Standard Review Plan limits (well within 10 CFR 100). | |||
Additionally, licensees adding the term "recently" must make the following commitment which is consistent with NUMARC 93-01, Revision 4, Section 11.3.6.5 "Safety Assessment for Removal of Equipment from Service During Shutdown Conditions," subheading "Containment - | |||
Primary (PWR)/Secondary (BWR)." | |||
"The following guidelines are included in the assessment of systems removed from service during movement irradiated fuel: | |||
3 | |||
- During fuel handling/core alterations, ventilation system and radiation monitor availability (as defined in NUMARC 91-06) should be assessed, with respect to filtration and monitoring of releases from the fuel. Following shutdown, radioactivity in the fuel decays away fairly rapidly. The basis of the Technical Specification OPERABILITY amendment is the reduction in doses due to such decay. The goal of maintaining ventilation system and radiation monitor availability is to reduce doses even further below that provided by the natural decay. | |||
- A single normal or contingency method to promptly close primary or secondary containment penetrations should be developed. Such prompt methods need not completely block the penetration or be capable of resisting pressure. | |||
The purpose of the "prompt methods" mentioned above are to enable ventilation systems to draw the release from a postulated fuel handling accident in the proper direction such that it can be treated and monitored." | |||

SURVEILLANCE SR 3.9.4.1 required is in the REQUIREMENTS This Surveillance demonstrates that each of the containment penetrations required to be in its closed position is in that position. The Surveillance status 2 | |||
vent on the open purge and exhaust valves will demonstrate that the valves are not blocked from closing. Also the Surveillance will demonstrate that each valve operator has motive power, which will ensure that each valve is capable of being closed by an OPERABLE automatic containment purge and exhaust isolation signal. | |||
The Surveillance is performed every 7 days during movement of [recently] 1 irradiated fuel assemblies within containment. The Surveillance interval is selected to be commensurate with the normal duration of time to complete fuel handling operations. A surveillance before the start of refueling operations will provide two or three surveillance verifications during the applicable period for this LCO. As such, this Surveillance ensures that a postulated fuel handling accident [involving handling 1 recently irradiated fuel] that releases fission product radioactivity within the containment will not result in a release of significant fission product radioactivity to the environment in excess of those recommended by Regulatory Guide 1.183 Standard Review Plan Section 15.7.4 (Reference 3). 2 1 | |||

SR 3.6.3.5 demonstrates that the isolation time of each valve is in accordance with the Inservice Testing Program requirements. These Surveillances performed during MODE 6 will ensure that the valves are capable of closing after a postulated fuel handling accident [involving 1 handling recently irradiated fuel] to limit a release of fission product 2 radioactivity from the containment. | |||

CTS 3.8.a.1 and 3.8.a.8 provide requirements for Containment Closure during refueling operations. | |||
The purpose of the Containment Closure during Refueling requirements is to restrict the release of fission product radioactivity within containment from escaping to the environment following a fuel handling accident within the containment. | |||
COMPARISON TO SCREENING CRITERIA: | |||
: 1. Containment closure is not installed instrumentation that is used to detect, and indicate in the control room, a significant abnormal degradation of the reactor coolant pressure boundary. | |||
: 2. Containment closure is not a process variable, design feature, or operating restriction that is in an initial condition of a DBA or Transient Analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. | |||
: 3. Containment closure is not a structure, system, or component that is part of the primary success path and which functions or actuates to mitigate a DBA or Transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. | |||
: 4. Containment closure was found to be non-significant risk contributor to core damage frequency and offsite releases. | |||
CONCLUSION: | |||
Since the screening criteria have not been satisfied, the Containment Closure Specifications may be relocated to other plant controlled documents outside Technical Specifications. | |||

NOTE: KAB-031 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 66 of 208 changes shown in green DISCUSSION OF CHANGES ITS 3.3.6, CONTAINMENT PURGE AND VENT ISOLATION INSTRUMENTATION The removal of these details, which are related to system design, from the Technical Specifications is acceptable because this type of information is not necessary to be included to provide adequate protection of public health and safety. The ITS still retains the requirement for the Containment Purge and Vent Isolation Instrumentation be OPERABLE and specifies the number of required channels. Also, this change is acceptable because the removed information will be adequately controlled in the ITS Bases. Changes to the Bases are controlled by the Technical Specification Bases Control Program in ITS Chapter 5. This program provides for the evaluation of changes to ensure the Bases are properly controlled. This change is designated as a less restrictive removal of detail change because information relating system design is being removed from the Technical Specifications. | |||
LESS RESTRICTIVE CHANGES L01 (Category 4 - Relaxation of Required Action) When both Containment Isolation Manual channels are inoperable, CTS Table TS 3.5-4 Column 6 requires the unit to be placed in HOT SHUTDOWN (ITS MODE 3).

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 67 of 208 L02 (Category 2 - Relaxation of Applicability) CTS 3.8.a.1.b requires an OPERABLE automatic isolation valve under certain conditions. This is referring to the Containment Purge and Vent System valves, and thus includes the instruments that provide the isolation signal. The Specification is applicable during REFUELING OPERATIONS. This requirement can be met by an OPERABLE automatic isolation valve or a closed isolation valve. When this requirement is not being met, CTS 3.8.b provides actions to be taken if any of the specified limiting conditions in CTS 3.8 a are not met during REFUELING OPERATIONS. ITS 3.3.6 is applicable, in part, during movement of irradiated fuel assemblies within containment, as stated in footnote (a) to Table 3.3.6-1. This changes the CTS by requiring the containment purge and vent isolation instrumentation be OPERABLE during times of movement of irradiated fuel assemblies within containment, in lieu of during REFUELING OPERATIONS. | |||
The purpose of CTS 3.8.a.1.b is to ensure each line that penetrates containment and provides a direct air path from containment atmosphere to the outside atmosphere have a closed isolation valve or an OPERABLE automatic isolation valve. Continuous monitoring of the radiation levels of the containment atmosphere (general or exhaust vent) is required to provide automatic action during an unsafe condition as a result of a fuel handling accident. CTS 3.8.a.1.b requires an OPERABLE automatic isolation valve during REFUELING OPERATIONS, and includes the isolation instrumentation. As defined in CTS Section 1.0, REFUELING OPERATIONS is movement of reactor vessel internal components that could affect the reactivity of the core within the containment when the vessel head is unbolted or removed. This would include both moving irradiated fuel assemblies and control rods. Since movement of irradiated fuel assemblies within containment can only occur when the vessel head is unbolted or removed, ITS 3.3.6 is applicable, with respect to moving fuel assemblies, under the same conditions as CTS 3.8.a.1.b. This change is acceptable because the requirements continue to ensure that the process variables are maintained in the MODES and other specified conditions assumed in the safety analyses and licensing basis. The fuel handling accident is based on damaging a single irradiated fuel assembly. Movement of control rods is not assumed to result in a fuel handling accident. This change is designated as less restrictive because the LCO requirements are applicable in fewer operating conditions than in the CTS. | |||
L03 (Category 4 - Relaxation of Required Action) CTS 3.8.a.1.b requires an OPERABLE automatic isolation valve under certain conditions. This is referring to the Containment Purge and Vent System valves, and thus includes the instruments that provide the isolation signal. The Specification is applicable during REFUELING OPERATIONS. | |||
When this requirement is not being met, the isolation valve must be closed or CTS 3.8.b requires refueling of the reactor to cease, initiation of action to restore the monitoring capability, and no operations be performed that could increase the reactivity of the core. | |||
Under similar conditions, ITS 3.3.6 does not require the refueling of the reactor to cease or require all operations that could increase the reactivity of the core to cease. With one radiation monitoring channel inoperable, ITS 3.3.6 ACTION A requires restoration of the affected channel to OPERABLE status within 4 hours. ITS 3.3.6 ACTION C, which is Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 67 of 208 | |||
Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 68 of 208 only applicable during the movement of irradiated fuel assemblies within containment, requires immediately placing and maintaining containment purge and vent valves in the closed position (Required Action C.1) or immediately entering the applicable Conditions and Required Actions of LCO 3.9.6 for containment purge and vent valves made inoperable by isolation instrumentation (Required Action C.2). Note that under this condition ITS LCO 3.9.6 would require suspension of movement of irradiated fuel assemblies in containment. This changes the CTS by deleting the requirements to cease refueling of the reactor and that no operations be performed that could increase the reactivity of the core and provides new ACTIONS to restore the radiation monitors to service and maintain the containment boundary. | |||
The purpose of CTS 3.8.a.1.b is to ensure the Containment Purge and Vent System is OPERABLE to provide automatic actuation of the valves if an unsafe condition as a result of a fuel handling accident occurs or the valves are closed. CTS 3.8.b requires compensatory actions be taken to exit the Applicability of the LCO if continuous monitoring is not available and the isolation valves cannot be closed; however, the CTS Actions are overly restrictive. The proposed compensatory actions of ITS 3.3.6 ACTIONS A and C ensure that acceptable actions are taken when radiation channels are inoperable. The proposed ACTION A is acceptable since channels are still available to ensure the containment purge and vent valve receive an isolation signal. The proposed ACTION C is acceptable since when multiple channels are inoperable, the proposed action places the containment purge and vent valves in the isolated position, which performs the function of the radiation channels. This change is designated as less restrictive since less restrictive actions have been added for when the radiation channels are inoperable. | |||

ISTS ISTS 3.9.4 has 3.3.6 ACTION B provides the actions when two or more radiation monitoring been channels are inoperable or when the Required Action and associated Completion renumbered to ITS 3.9.6. Time of Condition A (i.e., one radiation monitor is inoperable) is not met in MODES 1, 2, 3, and 4. ISTS 3.3.6 ACTION C provides the actions when two or more radiation monitoring channels are inoperable or when the Required Action and associated Completion Time of Condition A is not met during movement of recently irradiated fuel assemblies within containment. ISTS 3.3.6 ACTION C requires immediately placing and maintaining containment purge and exhaust valves in the closed position or to immediately enter the applicable Conditions and Required Actions of LCO 3.9.4, "Containment Penetrations," for containment purge and exhaust isolation valves made inoperable by isolation instrumentation. Kewaunee Power Station (KPS) does not credit containment isolation in a fuel handling accident analysis in the USAR. Therefore, ITS 3.3.6 does not maintain the applicability of during movement of recently irradiated fuel assemblies within containment as part of the Applicability. Therefore, all requirements related to movement of irradiated fuel assemblies in the containment (Table 3.3.6-1 Footnote (a) and ACTION C) have been deleted. In addition, due to this deletion, the Note to Condition B has been deleted since it is not necessary (there are no Actions other than those for MODES 1, 2, 3, and 4). | |||
: 4. The ISTS contains a Surveillance Requirement (SR) for an ACTUATION LOGIC TEST (ISTSSR 3.3.6.2) for the Containment Purge and Vent Isolation Instrumentation that is performed every 31 days on a STAGGERED TEST BASIS. | |||
The ISTS also contains an ACTUATION LOGIC TEST (ISTS SR 3.3.6.4) for the Containment Purge and Vent Isolation Instrumentation that is performed every 92 days on a STAGGERED TEST BASIS. ISTS SR 3.3.6.4 was added to the ISTS as part of the incorporation of TSTF-411, which, in part, increases the surveillance test interval (STI) for the actuation logic and actuation relays. The basis for the increase in the STI is WCAP-15376-P, Revision 0, which is consistent with the Nuclear Regulatory Commission's (NRC) approach for using probabilistic risk assessment in risk-informed decisions on plant-specific changes to the current licensing basis as presented in Regulatory Guides 1.174, "An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Current Licensing Basis," and 1.177, "An Approach for Plant-Specific, Risk-Informed Decisionmaking: Technical Specifications." KPS has elected to adopt the specific ISTS changes authorized by the results of WCAP-15376-P Revision 0. Therefore, the bracketed ISTS SR 3.3.6.4 (ITS SR 3.3.6.2) has been adopted for testing of the actuation logic and actuation relays. | |||
Subsequent Surveillance Requirements have been renumbered as a result of not including ISTS SR 3.3.6.2 in the ITS. | |||

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 77 of 208 Containment (Dual) 1 B 3.6.1B BASES LCO Containment OPERABILITY is maintained by limiting leakage to 1.0 La, except prior to the first startup after performing a required Containment Leakage Rate Testing Program leakage test. At this time the applicable leakage limits must be met. | |||
Compliance with this LCO will ensure a containment configuration, including equipment hatches, that is structurally sound and that will limit Note that while the Background section leakage to those leakage rates assumed in the safety analysis. 6 describes the Shield Building, the Shield Building requirements Individual leakage rates specified for the containment air lock (LCO 3.6.2) 9 are not covered by this LCO; they are provided | |||
[, purge valves with resilient seals, and secondary bypass leakage combined in LCO 3.6.8, "Shield (LCO 3.6.3)] are not specifically part of the acceptance criteria of Building." | |||
10 CFR 50, Appendix J. Therefore, leakage rates exceeding these individual limits only result in the containment being inoperable when the leakage results in exceeding the overall acceptance criteria of 1.0 La. | |||
APPLICABILITY In MODES 1, 2, 3, and 4, a DBA could cause a release of radioactive material into containment. In MODES 5 and 6, the probability and consequences of these events are reduced due to the pressure and temperature limitations of these MODES. Therefore, containment is not required to be OPERABLE in MODE 5 to prevent leakage of radioactive material from containment. The requirements for containment during MODE 6 are addressed in LCO 3.9.4, "Containment Penetrations." 11 3 | |||
ACTIONS A.1 6 In the event containment is inoperable, containment must be restored to OPERABLE status within 1 hour. The 1 hour Completion Time provides a period of time to correct the problem commensurate with the importance of maintaining containment OPERABLE during MODES 1, 2, 3, and 4. | |||
This time period also ensures that the probability of an accident (requiring containment OPERABILITY) occurring during periods when containment is inoperable is minimal. | |||
B.1 and B.2 If containment cannot be restored to OPERABLE status within the required Completion Time, the plant must be brought to a MODE in which the LCO does not apply. To achieve this status, the plant must be brought to at least MODE 3 within 6 hours and to MODE 5 within 36 hours. The allowed Completion Times are reasonable, based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems. | |||

This allowable leakage rate forms the basis for the acceptance criteria imposed on the SRs associated with the air locks. | ||
The containment air locks satisfy Criterion 3 of 10 CFR 50.36(c)(2)(ii). | |||
LCO Each containment air lock forms part of the containment pressure boundary. As part of the containment pressure boundary, the air lock safety function is related to control of the containment leakage rate resulting from a DBA. Thus, each air lock's structural integrity and leak tightness are essential to the successful mitigation of such an event. | |||
Each air lock is required to be OPERABLE. For the air lock to be considered OPERABLE, the air lock interlock mechanism must be OPERABLE, the air lock must be in compliance with the Type B air lock leakage test, and both air lock doors must be OPERABLE. The interlock allows only one air lock door of an air lock to be opened at one time. This provision ensures that a gross breach of containment does not exist when containment is required to be OPERABLE. Closure of a single door in each air lock is sufficient to provide a leak tight barrier following postulated events. Nevertheless, both doors are kept closed when the air lock is not being used for normal entry into or exit from containment. | |||
APPLICABILITY In MODES 1, 2, 3, and 4, a DBA could cause a release of radioactive material to containment. In MODES 5 and 6, the probability and consequences of these events are reduced due to the pressure and temperature limitations of these MODES. Therefore, the containment air locks are not required in MODE 5 to prevent leakage of radioactive material from containment. The requirements for the containment air locks during MODE 6 are addressed in LCO 3.9.3, "Containment 10 Penetrations." 6 ACTIONS The ACTIONS are modified by a Note that allows entry and exit to If the inner 5 perform repairs on the affected air lock component. If the outer door is door is inoperable, inoperable, then it may be easily accessed for most repairs. It is then preferred that the air lock be accessed from inside primary containment by entering through the other OPERABLE air lock. However, if this is not practicable, or if repairs on either door must be performed from the barrel side of the door then it is permissible to enter the air lock through the OPERABLE door, which means there is a short time during which the containment boundary is not intact (during access through the WOG STS B 3.6.2-2 Rev. 3.0, 03/31/04 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 78 of 208 | |||

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 83 of 208 DISCUSSION OF CHANGES ITS 3.9.3, RHR AND COOLANT CIRCULATION - HIGH WATER LEVEL verification that each penetration providing direct access from the containment atmosphere to the outside atmosphere is either closed with a manual or an OPERABLE automatic isolation valve, blind flange, or equivalent, or is capable of being closed by a Containment Ventilation and Purge Isolation System in 4 hours (Required Action A.6). This changes the CTS by adding new Required Actions when the required RHR loop is inoperable. and Vent These added Required Actions are acceptable since they assist in minimizing the consequences of the required RHR loop being inoperable. Note that while CTS 3.8.b requires operations not be performed that could increase the reactivity of the core, this action is actually not required to be taken since once movement of fuel has been suspended, REFUELING OPERATIONS has ceased (thus, the LCO requirements of CTS 3.8.a are not required to be met). Thus, the addition of a similar Required Action (Required Action A.1), as well as the other above described Required Actions, is designated as more restrictive. | |||
M03 CTS 3.1.a.1.A does not contain any ACTIONS to take should there be less than the required number of RHR pumps in operation. As a result, CTS 3.0.c would normally be entered. However, LCO 3.0.c states that it is not applicable in COLD SHUTDOWN or REFUELING. Since the RHR pump only has to be in operation when a reduction in boron concentration is being made, and for this Specification, the unit is already in MODE 6, the CTS does not provide any compensatory measures. Therefore, 10 CFR 50.36 (c)(2)(i) would apply, which states to shutdown the unit. However, no times are provided to complete the shutdown and no further actions (i.e., suspend boron concentration reductions) are required. Note that while no ACTIONS are required, KPS in all likelihood would suspend dilution if this occurred. ITS 3.9.3 ACTION A specifies the Required Actions for a required RHR loop not in operation, and requires immediate suspension of operations that would cause introduction of coolant into the RCS with a boron concentration less than required to meet the boron concentration of LCO 3.9.1 (Required Action A.1), immediate suspension of loading irradiated fuel assemblies into the core (Required Action A.2), immediate initiation of action to restore one RHR loop to operation (Required Action A.3), | |||
closing the equipment hatch and securing it with four bolts in 4 hours (Required Action A.4), closing one door in each air lock in 4 hours (Required Action A.5), | |||
and a verification that each penetration providing direct access from the containment atmosphere to the outside atmosphere is either closed with a an OPERABLE manual or automatic isolation valve, blind flange, or equivalent, or is capable of being closed by a Containment Ventilation Isolation System in 4 hours (Required Action A.6). This changes the CTS by adding a new ACTION. | |||
Purge and Vent The purpose of the Actions should be to place the unit outside of the Applicability of the Specification. ITS 3.9.3 ACTION A effectively places the unit in an equivalent condition by requiring the plant to immediately suspend operations that would cause introduction of coolant into the RCS with a boron concentration less than required to meet the boron concentration of LCO 3.9.1 and to initiate action to restore one RHR loop to operation. The proposed Required Actions reflect the importance of maintaining operation for decay heat removal and boron mixing. This change is designated as more restrictive because a new proposed ACTION has been added. | |||

This changes the CTS by adding a new ACTION when both required RHR loops are inoperable. | ||
The change is acceptable because the Completion Times are consistent with safe operation under the specified Condition, considering the OPERABLE status of the redundant systems or features, a reasonable time for repairs or replacement, and the low probability of a DBA occurring during the allowed Completion Times. The immediate initiation of action to restore the required loops to OPERABLE status or to establish 23 ft of water above the top of the reactor vessel flange reflects the importance of maintaining operation for decay heat removal. This change is designated as more restrictive because a new ACTION is being added to the ITS that was not required by the CTS. | |||
M03 CTS 3.1.a.1.A does not contain any ACTIONS to take should there be less than the required number of RHR pumps in operation. As a result, CTS 3.0.c would normally be entered. However, LCO 3.0.c states that it is not applicable in COLD SHUTDOWN or REFUELING. Since the RHR pump only has to be in operation when a reduction in boron concentration is being made, and for this specification, the unit is already in MODE 6, the CTS does not provide any compensatory measures. Therefore, 10 CFR 50.36 (c)(2)(i) would apply, which states to shut down the unit. However, no times are provided to complete the shutdown and no further actions (i.e., suspend boron concentration reductions) are required. Note that while no ACTIONS are required, KPS in all likelihood would suspend dilution if this occurred. ITS 3.9.4 ACTION B specifies the Required Actions for a required RHR loop not in operation, and requires immediate suspension of operations that would cause introduction of coolant into the RCS with a boron concentration less than required to meet the boron concentration of LCO 3.9.1 (Required Action B.1), immediate initiation of action to restore one RHR loop to operation (Required Action B.2), closing the equipment hatch and securing it with four bolts in 4 hours (Required Action B.3), closing one door in each air lock in 4 hours (Required Action B.4), and a verification that each penetration providing direct access from the containment atmosphere to the outside atmosphere is an OPERABLE either closed with a manual or automatic isolation valve, blind flange, or equivalent, or is capable of being closed by a Containment Ventilation Isolation System in 4 hours (Required Action B.5). This changes the CTS by adding a new ACTION. Purge and Vent The purpose of the Actions should be to place the unit outside of the Applicability of the Specification. ITS 3.9.4 ACTION B effectively places the unit in an equivalent condition by requiring the plant to immediately suspend operations that would cause introduction of coolant into the RCS with a boron concentration less than required to meet the boron concentration of LCO 3.9.1 and to initiate action to restore one RHR loop to operation. The proposed Required Actions reflect the importance of maintaining operation for decay heat removal and boron mixing. This change is designated as more restrictive because a new proposed ACTION has been added. | |||

ISTS 3.9.6 Required Actions B.5.1 and B.5.2 are connected by an "OR" logical connector, such that either one can be performed to meet the requirements of the ACTION. However, the two Required Actions are applicable to all the penetrations; either Required Action B.5.1 or Required Action B.5.2 must be performed for all the penetrations. Thus, this will not allow one penetration to be isolated by use of a manual valve and another penetration to be capable of being closed by an OPERABLE Containment Purge and Exhaust Isolation System. This is not the intent of the requirement. The requirement is based on ISTS LCO 3.9.4, which requires each penetration to be either: a) closed by a manual or automatic isolation valve, blind flange, or equivalent; or b) capable of being closed by an OPERABLE Containment Purge and Exhaust Isolation System. For consistency with the actual LCO requirement, ISTS 3.9.6 Required Actions B.5.1 and B.5.2 have been combined into a single Required Action in ITS 3.9.4 Required Action B.5.

Consistent with TSTF-265, a Note is added to ITS SR 3.9.4.2 that permits the performance of the SR to verify correct breaker alignment and power availability to be delayed until 24 hours after a required RHR pump is not in operation. This provision is required because when RHR pumps are swapped under the current requirements, the Surveillance is immediately not met on the RHR pump taken out of operation. This change avoids entering an Action for a routine operational occurrence. The change is acceptable because adequate assurance exists that the RHR pump is aligned to the correct breaker with power available because, prior to being removed from operation, the applicable pump had been in operation. Allowing 24 hours to perform the breaker alignment verification is acceptable because the RHR pump was in operation, which demonstrated OPERABILITY, and because 24 hours is allowed in the ISTS by Kewaunee Power Station Page 1 of 2 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 90 of 208 | |||

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 99 of 208 DISCUSSION OF CHANGES CTS 3.8.a.1 and 3.8.a.8, CONTAINMENT PENETRATIONS ADMINISTRATIVE CHANGES None MORE RESTRICTIVE CHANGES None RELOCATED SPECIFICATIONS R01 CTS 3.8.a.1 and 3.8.a.8 provide requirements for Containment Closure during refueling operations. The purpose of the Containment Closure during Refueling requirements is to restrict the release of fission product radioactivity within containment from escaping to the environment following a fuel handling accident within the containment. The containment closure is not taken credit for in any accident analyses in the USAR. This is also documented in the NRC Safety Evaluation for License Amendment 190, dated March 8, 2007 (ADAMS Accession No. ML070430020). Therefore, the ITS does not include these Specifications. This changes the CTS by relocating the Containment Closure Specifications to the Technical Requirements Manual (TRM). | |||
This change is acceptable because CTS 3.8.a.1 and 3.8.a.8 do not meet the 10 CFR 50.36(c)(2)(ii) criteria for inclusion into the ITS. | |||
10 CFR 50.36(c)(2)(ii) Criteria Evaluation: | |||
: 1. Containment closure is not installed instrumentation that is used to detect, and indicate in the control room, a significant abnormal degradation of the reactor coolant pressure boundary. The Containment Closure Specifications do not satisfy criterion 1. | |||
: 2. Containment closure is not a process variable, design feature, or operating restriction that is in an initial condition of a DBA or Transient Analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. The Containment Closure Specifications do not satisfy criterion 2. | |||
: 3. Containment closure is not a structure, system, or component that is part of the primary success path and which functions or actuates to mitigate a DBA or Transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. The Containment Closure Specifications do not satisfy criterion 3. | |||
: 4. Containment closure was found to be non-significant risk contributor to core damage frequency and offsite releases. Dominion Energy Kewaunee (DEK) has performed a plant specific evaluation to ensure that the Containment Closure requirements do not contain constraints of prime importance in limiting the likelihood or severity of the accident Kewaunee Power Station Page 1 of 2 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 99 of 208 | |||

CTS 3.8.a.1 and 3.8.a.8 | Since the 10 CFR 50.36(c)(2)(ii) criteria have not been met, the Containment Closure Specifications (CTS 3.8.a.1 and 3.8.a.8) may be relocated out of the Technical Specifications. The containment closure specification will be relocated to the TRM. Changes to the TRM will be controlled by the provisions of 10 CFR 50.59. This change is designated as relocation because the specifications did not meet the criteria in 10 CFR 50.36(c)(2)(ii) and has been relocated to the TRM. | ||

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 123 of 208 DISCUSSION OF CHANGES ITS 3.9.6, CONTAINMENT PENETRATIONS ADMINISTRATIVE CHANGES A01 In the conversion of the Kewaunee Power Station (KPS) Current Technical Specifications (CTS) to the plant specific Improved Technical Specifications (ITS), certain changes (wording preferences, editorial changes, reformatting, revised numbering, etc.) are made to obtain consistency with NUREG-1431, Rev. 3.0, "Standard Technical Specifications-Westinghouse Plants" (ISTS). | |||
These changes are designated as administrative changes and are acceptable because they do not result in technical changes to the CTS. | |||
A02 When the containment penetrations are not in the required condition specified in CTS 3.8.a.1 or CTS 3.8.a.8, CTS 3.8.b requires refueling of the reactor to cease, initiation of action to restore the containment penetrations to the required conditions, and no operations be performed that could increase the reactivity of the core. Under similar conditions, ITS 3.9.6 ACTION A only requires movement of irradiated fuel assemblies within containment to be suspended. This changes the CTS by deleting the requirements to initiate action to restore the containment penetrations to the required conditions and that no operations be performed that could increase the reactivity of the core. | |||
The purpose of CTS 3.8.a.8 is to ensure proper compensatory actions are taken to exit the Applicability of the LCO. CTS 3.8.a.1 and 3.8.a.8 are only applicable during REFUELING OPERATIONS, which is defined in CTS Section 1.0 as the movement of reactor vessel internals that could affect the reactivity of the core within the containment when the vessel head is unbolted or removed. Thus, after the first requirement of CTS 3.8.b is met (i.e., suspend refueling the reactor), the Applicability has been exited and thus, continuation of the requirements of CTS 3.8.b are not required. Therefore, this change is acceptable and is designated as administrative since the technical requirements have not been changed. | The purpose of CTS 3.8.a.8 is to ensure proper compensatory actions are taken to exit the Applicability of the LCO.

Therefore, this change is acceptable and is designated as administrative since the technical requirements have not been changed. | ||
MORE RESTRICTIVE CHANGES M01 CTS 3.8.a does not provide a Surveillance Requirement to verify each required containment penetration is in the required status. The ITS adds a Surveillance Requirement (SR 3.9.6.1) to verify each required containment penetration is in the required status once every 7 days. This changes the CTS by adding a new Surveillance Requirement for the containment penetrations. | MORE RESTRICTIVE CHANGES M01 CTS 3.8.a does not provide a Surveillance Requirement to verify each required containment penetration is in the required status.

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 124 of 208 DISCUSSION OF CHANGES ITS 3.9.6, CONTAINMENT PENETRATIONS RELOCATED SPECIFICATIONS None REMOVED DETAIL CHANGES LA01 (Type 3 - Removing Procedural Details for Meeting TS Requirements or Reporting Requirements) CTS 3.8.a.1.a requires at least one door in each personnel air lock to be capable of being closed "within 30 minutes." | |||
CTS 3.8.a.1.a is modified by a footnote (1) that states "Administrative controls ensure that appropriate personnel are aware that both personnel air lock doors are open; a specified individual(s) is designated and available to close the air lock following a required evacuation of containment; and, any obstruction(s) (e.g., | |||
cables and hoses) that could prevent closure of an open air lock can be quickly removed." ITS 3.9.6 does not contain this footnote information or the 30 minute requirement. This changes the CTS by moving the information contained in the footnote and the 30 minute requirement to the Bases. | |||
The removal of these details, which are related to procedural details for meeting Technical Specification requirements, from the Technical Specifications is acceptable because this type of information is not necessary to be included in the Technical Specifications to provide adequate protection of public health and safety. The ITS still retains the requirement for at least one door in each personnel air lock to be capable of being closed. Also, this change is acceptable because the removed information will be adequately controlled in the ITS Bases. | |||
Changes to the Bases are controlled by the Technical Specification Bases Control Program in Chapter 5. This program provides for the evaluation of changes to ensure the Bases are properly controlled. This change is designated as a less restrictive removal of detail change because information relating to procedural details for meeting Technical Specification requirements is being removed from the Technical Specifications. | |||
LESS RESTRICTIVE CHANGES L01 (Category 1 - Relaxation of LCO Requirements) CTS 3.8.a.1.a, in part, requires at least one door in each personnel air lock to be closed when the reactor vessel head or upper internals are being lifted. ITS 3.9.6 does not include this requirement. This changes the CTS by not requiring one door in each personnel air lock to be closed when the reactor vessel head or upper internals are being lifted. | |||
The purpose of CTS 3.8.a.1 is to ensure that if a fuel handling accident occurs, the release of any subsequent fission products results in doses that are well within the guideline values specified in Regulatory Guide 1.183. A fuel handling accident, as analyzed in USAR Section 14.2.1, is postulated to occur during handling of irradiated fuel assemblies; not handling the vessel head or upper internals. Thus, moving the vessel head or upper internals cannot result in a fuel handling accident. Any additional requirements, above those required to meet the assumptions of the fuel handling accident, are more appropriately controlled Kewaunee Power Station Page 2 of 4 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 124 of 208 | |||

Therefore, this change is acceptable and is designated a less restrictive change since the requirement to maintain containment closure capability during movement of the vessel head or upper internals is being deleted from the CTS. | |||
L02 (Category 1 - Relaxation of LCO Requirements) CTS 3.8.a.1.b, in part, states that each line that penetrates containment and which provides a direct air path from containment atmosphere to the outside atmosphere shall have a closed isolation valve. ITS LCO 3.9.6.c.1 states that each penetration providing direct access from the containment atmosphere to the outside atmosphere is closed by a manual or automatic isolation valve, blind flange, or equivalent. This changes the CTS by specifying the use of a blind flange or an equivalent means of isolating a containment penetration. | |||
The purpose of CTS 3.8.a.1 is to ensure the containment penetrations are in the condition assumed in the Fuel Handling Accident (FHA) analysis. This change is acceptable because the LCO requirements continue to ensure that the structures, systems, and components are maintained consistent with the safety analyses and licensing basis. The addition of the option to use a blind flange or some other equivalent means of isolating the containment penetration allows additional flexibility in the ITS that was not available in CTS. This change is designated as less restrictive because less stringent LCO requirements are being applied in the ITS than were applied in the CTS. | The purpose of CTS 3.8.a.1 is to ensure the containment penetrations are in the condition assumed in the Fuel Handling Accident (FHA) analysis.

L05 (Category 1 - Relaxation of LCO Requirements) CTS 3.8.a specifies that the CTS 3.8.a.1 containment closure requirements are applicable during REFUELING OPERATIONS, which is defined in CTS Section 1.0 as the movement of reactor vessel internals that could affect the reactivity of the core within the containment when the vessel head is unbolted or removed. ITS 3.9.6 is applicable during movement of irradiated fuel assemblies within containment. | |||
This changes the CTS by not requiring the containment closure requirements to be met when moving or handling control rods during MODE 6 operation. | |||
The purpose of CTS 3.8.a.1 is to ensure that if a fuel handling accident occurs, the release of any subsequent fission products results in doses that are well within the guideline values specified in Regulatory Guide 1.183. A fuel handling accident, as analyzed in USAR Section 14.2.1, can only occur during handling of irradiated fuel assemblies; not moving or handling control rods (which are the only other reactor vessel internals currently in use at KPS that could affect reactivity of the core). Thus, moving or handling the control rods cannot result in a fuel handling accident. Any additional requirements, above those required to meet the assumptions of the fuel handling accident, are more appropriately controlled by plant procedures. Therefore, this change is acceptable and is designated a less restrictive change since the requirement to maintain containment closure capability during movement or handling of control rods in MODE 6 is being deleted from the CTS. | |||

BASES BACKGROUND During movement of [recently] irradiated fuel assemblies within containment, a release of fission product radioactivity within containment will be restricted from escaping to the environment when the LCO requirements are met. In MODES 1, 2, 3, and 4, this is accomplished by maintaining containment OPERABLE as described in LCO 3.6.1, "Containment." In MODE 6, the potential for containment pressurization as a result of an accident is not likely; therefore, requirements to isolate the containment from the outside atmosphere can be less stringent. The LCO requirements are referred to as "containment closure" rather than "containment OPERABILITY." Containment closure means that all potential escape paths are closed or capable of being closed. Since there is no potential for containment pressurization, the Appendix J leakage criteria and tests are not required. | |||
The containment serves to contain fission product radioactivity that may be released from the reactor core following an accident, such that offsite radiation exposures are maintained well within the requirements of guidance 2 Regulatory Guide 1.183 (Ref. 1) 10 CFR 100. Additionally, the containment provides radiation shielding from the fission products that may be present in the containment atmosphere following accident conditions. | |||
The containment equipment hatch, which is part of the containment pressure boundary, provides a means for moving large equipment and components into and out of containment. During movement of [recently] | |||
irradiated fuel assemblies within containment, the equipment hatch must be held in place by at least four bolts. Good engineering practice dictates that the bolts required by this LCO be approximately equally spaced. | |||
The containment air locks, which are also part of the containment pressure boundary, provide a means for personnel access during MODES 1, 2, 3, and 4 unit operation in accordance with LCO 3.6.2, "Containment Air Locks." Each air lock has a door at both ends. The doors are normally interlocked to prevent simultaneous opening when containment OPERABILITY is required. During periods of unit shutdown when containment closure is not required, the door interlock mechanism may be disabled, allowing both doors of an air lock to remain open for extended periods when frequent containment entry is necessary. | |||

LCO ----------------------------------- | The allowance to have containment personnel air lock doors open and TSTF-471-A penetration flow paths with direct access from the containment atmosphere to the outside atmosphere to be unisolated during fuel movement and CORE ALTERATIONS is based on (1) confirmatory dose calculations of a fuel handling accident as approved by the NRC staff which indicate acceptable radiological consequences and 3 (2) commitments from the licensee to implement acceptable administrative procedures that ensure in the event of a refueling accident (even though the containment fission product control function is not required to meet acceptable dose consequences) that the open air lock can and will be promptly closed following containment evacuation and that the open penetration(s) can and will be promptly closed.

This LCO limits the consequences of a fuel handling accident [involving 2 handling recently irradiated fuel] in containment by limiting the potential escape paths for fission product radioactivity released within containment. | |||

The OPERABILITY requirements for this LCO ensure 2 that the automatic purge and exhaust valve closure times specified in the FSAR can be achieved and, therefore, meet the assumptions used in the safety analysis to ensure that releases through the valves are terminated, such that radiological doses are within the acceptance limit. | ||
The LCO is modified by a Note allowing penetration flow paths with direct 8 access from the containment atmosphere to the outside atmosphere to be unisolated under administrative controls. Administrative controls ensure that 1) appropriate personnel are aware of the open status of the TSTF-471-A penetration flow path during CORE ALTERATIONS or movement of irradiated fuel assemblies within containment, and 2) specified individuals are designated and readily available to isolate the flow path in the event of a fuel handling accident. | |||

APPLICABILITY The containment penetration requirements are applicable during 1 | |||
movement of [recently] irradiated fuel assemblies within containment because this is when there is a potential for the limiting fuel handling accident. In MODES 1, 2, 3, and 4, containment penetration requirements are addressed by LCO 3.6.1. In MODES 5 and 6, when movement of irradiated fuel assemblies within containment is not being conducted, the potential for a fuel handling accident does not exist. | |||
[Additionally, due to radioactive decay, a fuel handling accident involving handling recently irradiated fuel (i.e., fuel that has occupied part of a 1 critical reactor core within the previous [x] days) will result in doses that are well within the guideline values specified in 10 CFR 100 even without containment closure capability.] Therefore, under these conditions no requirements are placed on containment penetration status. | |||

-----------------------------------REVIEWERS NOTE----------------------------------- | |||
The addition of the term "recently" associated with handling irradiated fuel in all of the containment function Technical Specification requirements is only applicable to those licensees who have demonstrated by analysis that after sufficient radioactive decay has occurred, off-site doses resulting from a fuel handling accident remain below the Standard Review Plan limits (well within 10 CFR 100). | |||
Additionally, licensees adding the term "recently" must make the following commitment which is consistent with NUMARC 93-01, Revision 4, Section 11.3.6.5 "Safety Assessment for Removal of Equipment from Service During Shutdown Conditions," subheading "Containment - | |||
Primary (PWR)/Secondary (BWR)." | |||
"The following guidelines are included in the assessment of systems removed from service during movement irradiated fuel: | |||
3 | |||
- During fuel handling/core alterations, ventilation system and radiation monitor availability (as defined in NUMARC 91-06) should be assessed, with respect to filtration and monitoring of releases from the fuel. Following shutdown, radioactivity in the fuel decays away fairly rapidly. The basis of the Technical Specification OPERABILITY amendment is the reduction in doses due to such decay. The goal of maintaining ventilation system and radiation monitor availability is to reduce doses even further below that provided by the natural decay. | |||
- A single normal or contingency method to promptly close primary or secondary containment penetrations should be developed. Such prompt methods need not completely block the penetration or be capable of resisting pressure. | |||
The purpose of the "prompt methods" mentioned above are to enable ventilation systems to draw the release from a postulated fuel handling accident in the proper direction such that it can be treated and monitored." | |||

vent on the open purge and exhaust valves will demonstrate that the valves are not blocked from closing. Also the Surveillance will demonstrate that each valve operator has motive power, which will ensure that each valve is capable of being closed by an OPERABLE automatic containment purge and exhaust isolation signal. | |||
The Surveillance is performed every 7 days during movement of [recently] 1 irradiated fuel assemblies within containment. The Surveillance interval is selected to be commensurate with the normal duration of time to complete fuel handling operations. A surveillance before the start of refueling operations will provide two or three surveillance verifications during the applicable period for this LCO. As such, this Surveillance ensures that a postulated fuel handling accident [involving handling 1 recently irradiated fuel] that releases fission product radioactivity within the containment will not result in a release of significant fission product radioactivity to the environment in excess of those recommended by Regulatory Guide 1.183 Standard Review Plan Section 15.7.4 (Reference 3). 2 1 | |||

These Surveillances performed during MODE 6 will ensure that the valves are capable of closing after a postulated fuel handling accident [involving 1 handling recently irradiated fuel] to limit a release of fission product 2 radioactivity from the containment. | |||
The SR is modified by a Note stating that this Surveillance is not required to be met for valves in isolated penetrations. The LCO provides the option to close penetrations in lieu of requiring automatic actuation capability. | |||

The ITS still retains the requirement for the Containment Purge and Vent Isolation Instrumentation be OPERABLE and specifies the number of required channels. Also, this change is acceptable because the removed information will be adequately controlled in the ITS Bases. Changes to the Bases are controlled by the Technical Specification Bases Control Program in ITS Chapter 5. This program provides for the evaluation of changes to ensure the Bases are properly controlled. This change is designated as a less restrictive removal of detail change because information relating system design is being removed from the Technical Specifications. | |||

This is referring to the Containment Purge and Vent System valves, and thus includes the instruments that provide the isolation signal. The Specification is applicable during REFUELING OPERATIONS. This requirement can be met by an OPERABLE automatic isolation valve or a closed isolation valve. When this requirement is not being met, CTS 3.8.b provides actions to be taken if any of the specified limiting conditions in CTS 3.8 a are not met during REFUELING OPERATIONS. ITS 3.3.6 is applicable, in part, during movement of irradiated fuel assemblies within containment, as stated in footnote (a) to Table 3.3.6-1. This changes the CTS by requiring the containment purge and vent isolation instrumentation be OPERABLE during times of movement of irradiated fuel assemblies within containment, in lieu of during REFUELING OPERATIONS. | ||
The purpose of CTS 3.8.a.1.b is to ensure each line that penetrates containment and provides a direct air path from containment atmosphere to the outside atmosphere have a closed isolation valve or an OPERABLE automatic isolation valve. Continuous monitoring of the radiation levels of the containment atmosphere (general or exhaust vent) is required to provide automatic action during an unsafe condition as a result of a fuel handling accident. CTS 3.8.a.1.b requires an OPERABLE automatic isolation valve during REFUELING OPERATIONS, and includes the isolation instrumentation. As defined in CTS Section 1.0, REFUELING OPERATIONS is movement of reactor vessel internal components that could affect the reactivity of the core within the containment when the vessel head is unbolted or removed. This would include both moving irradiated fuel assemblies and control rods. Since movement of irradiated fuel assemblies within containment can only occur when the vessel head is unbolted or removed, ITS 3.3.6 is applicable, with respect to moving fuel assemblies, under the same conditions as CTS 3.8.a.1.b. This change is acceptable because the requirements continue to ensure that the process variables are maintained in the MODES and other specified conditions assumed in the safety analyses and licensing basis. The fuel handling accident is based on damaging a single irradiated fuel assembly. Movement of control rods is not assumed to result in a fuel handling accident. This change is designated as less restrictive because the LCO requirements are applicable in fewer operating conditions than in the CTS. | |||
L03 (Category 4 - Relaxation of Required Action) CTS 3.8.a.1.b requires an OPERABLE automatic isolation valve under certain conditions. This is referring to the Containment Purge and Vent System valves, and thus includes the instruments that provide the isolation signal. The Specification is applicable during REFUELING OPERATIONS. | |||
When this requirement is not being met, the isolation valve must be closed or CTS 3.8.b requires refueling of the reactor to cease, initiation of action to restore the monitoring capability, and no operations be performed that could increase the reactivity of the core. | |||
Under similar conditions, ITS 3.3.6 does not require the refueling of the reactor to cease or require all operations that could increase the reactivity of the core to cease. With one radiation monitoring channel inoperable, ITS 3.3.6 ACTION A requires restoration of the affected channel to OPERABLE status within 4 hours. ITS 3.3.6 ACTION C, which is Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 158 of 208 | |||
Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 159 of 208 only applicable during the movement of irradiated fuel assemblies within containment, requires immediately placing and maintaining containment purge and vent valves in the closed position (Required Action C.1) or immediately entering the applicable Conditions and Required Actions of LCO 3.9.6 for containment purge and vent valves made inoperable by isolation instrumentation (Required Action C.2). Note that under this condition ITS LCO 3.9.6 would require suspension of movement of irradiated fuel assemblies in containment. This changes the CTS by deleting the requirements to cease refueling of the reactor and that no operations be performed that could increase the reactivity of the core and provides new ACTIONS to restore the radiation monitors to service and maintain the containment boundary. | |||
The purpose of CTS 3.8.a.1.b is to ensure the Containment Purge and Vent System is OPERABLE to provide automatic actuation of the valves if an unsafe condition as a result of a fuel handling accident occurs or the valves are closed. CTS 3.8.b requires compensatory actions be taken to exit the Applicability of the LCO if continuous monitoring is not available and the isolation valves cannot be closed; however, the CTS Actions are overly restrictive. The proposed compensatory actions of ITS 3.3.6 ACTIONS A and C ensure that acceptable actions are taken when radiation channels are inoperable. The proposed ACTION A is acceptable since channels are still available to ensure the containment purge and vent valve receive an isolation signal. The proposed ACTION C is acceptable since when multiple channels are inoperable, the proposed action places the containment purge and vent valves in the isolated position, which performs the function of the radiation channels. This change is designated as less restrictive since less restrictive actions have been added for when the radiation channels are inoperable. | |||

Time of Condition A (i.e., one radiation monitor is inoperable) is not met in MODES 1, 2, 3, and 4. ISTS 3.3.6 ACTION C provides the actions when two or more radiation monitoring channels are inoperable or when the Required Action and associated Completion Time of Condition A is not met during movement of recently irradiated fuel assemblies within containment. ISTS 3.3.6 ACTION C requires immediately placing and maintaining containment purge and exhaust valves in the closed position or to immediately enter the applicable Conditions and Required Actions of LCO 3.9.4, "Containment Penetrations," for containment purge and exhaust isolation valves made inoperable by isolation instrumentation. Kewaunee Power Station (KPS) does not credit containment isolation in a fuel handling accident analysis in the USAR. Therefore, ITS 3.3.6 does not maintain the applicability of during movement of recently irradiated fuel assemblies within containment as part of the Applicability. Therefore, all requirements related to movement of irradiated fuel assemblies in the containment (Table 3.3.6-1 Footnote (a) and ACTION C) have been deleted. In addition, due to this deletion, the Note to Condition B has been deleted since it is not necessary (there are no Actions other than those for MODES 1, 2, 3, and 4). | |||
: 4. The ISTS contains a Surveillance Requirement (SR) for an ACTUATION LOGIC TEST (ISTSSR 3.3.6.2) for the Containment Purge and Vent Isolation Instrumentation that is performed every 31 days on a STAGGERED TEST BASIS. | |||
The ISTS also contains an ACTUATION LOGIC TEST (ISTS SR 3.3.6.4) for the Containment Purge and Vent Isolation Instrumentation that is performed every 92 days on a STAGGERED TEST BASIS. ISTS SR 3.3.6.4 was added to the ISTS as part of the incorporation of TSTF-411, which, in part, increases the surveillance test interval (STI) for the actuation logic and actuation relays. The basis for the increase in the STI is WCAP-15376-P, Revision 0, which is consistent with the Nuclear Regulatory Commission's (NRC) approach for using probabilistic risk assessment in risk-informed decisions on plant-specific changes to the current licensing basis as presented in Regulatory Guides 1.174, "An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Current Licensing Basis," and 1.177, "An Approach for Plant-Specific, Risk-Informed Decisionmaking: Technical Specifications." KPS has elected to adopt the specific ISTS changes authorized by the results of WCAP-15376-P Revision 0. Therefore, the bracketed ISTS SR 3.3.6.4 (ITS SR 3.3.6.2) has been adopted for testing of the actuation logic and actuation relays. | |||
Subsequent Surveillance Requirements have been renumbered as a result of not including ISTS SR 3.3.6.2 in the ITS. | |||

At this time the applicable leakage limits must be met. | |||
Compliance with this LCO will ensure a containment configuration, including equipment hatches, that is structurally sound and that will limit Note that while the Background section leakage to those leakage rates assumed in the safety analysis. 6 describes the Shield Building, the Shield Building requirements Individual leakage rates specified for the containment air lock (LCO 3.6.2) 9 are not covered by this LCO; they are provided | |||

10 CFR 50, Appendix J. Therefore, leakage rates exceeding these individual limits only result in the containment being inoperable when the leakage results in exceeding the overall acceptance criteria of 1.0 La. | |||
APPLICABILITY In MODES 1, 2, 3, and 4, a DBA could cause a release of radioactive material into containment. In MODES 5 and 6, the probability and consequences of these events are reduced due to the pressure and temperature limitations of these MODES. Therefore, containment is not required to be OPERABLE in MODE 5 to prevent leakage of radioactive material from containment. The requirements for containment during MODE 6 are addressed in LCO 3.9.4, "Containment Penetrations." 11 3 | |||
ACTIONS A.1 6 In the event containment is inoperable, containment must be restored to OPERABLE status within 1 hour. The 1 hour Completion Time provides a period of time to correct the problem commensurate with the importance of maintaining containment OPERABLE during MODES 1, 2, 3, and 4. | |||
This time period also ensures that the probability of an accident (requiring containment OPERABILITY) occurring during periods when containment is inoperable is minimal. | |||
B.1 and B.2 If containment cannot be restored to OPERABLE status within the required Completion Time, the plant must be brought to a MODE in which the LCO does not apply. To achieve this status, the plant must be brought to at least MODE 3 within 6 hours and to MODE 5 within 36 hours. The allowed Completion Times are reasonable, based on operating experience, to reach the required plant conditions from full power conditions in an orderly manner and without challenging plant systems. | |||

This allowable leakage rate forms the basis for the acceptance criteria imposed on the SRs associated with the air locks. | |||
The containment air locks satisfy Criterion 3 of 10 CFR 50.36(c)(2)(ii). | |||
LCO Each containment air lock forms part of the containment pressure boundary. As part of the containment pressure boundary, the air lock safety function is related to control of the containment leakage rate resulting from a DBA. Thus, each air lock's structural integrity and leak tightness are essential to the successful mitigation of such an event. | |||
Each air lock is required to be OPERABLE. For the air lock to be considered OPERABLE, the air lock interlock mechanism must be OPERABLE, the air lock must be in compliance with the Type B air lock leakage test, and both air lock doors must be OPERABLE. The interlock allows only one air lock door of an air lock to be opened at one time. This provision ensures that a gross breach of containment does not exist when containment is required to be OPERABLE. Closure of a single door in each air lock is sufficient to provide a leak tight barrier following postulated events. Nevertheless, both doors are kept closed when the air lock is not being used for normal entry into or exit from containment. | |||
APPLICABILITY In MODES 1, 2, 3, and 4, a DBA could cause a release of radioactive material to containment. In MODES 5 and 6, the probability and consequences of these events are reduced due to the pressure and temperature limitations of these MODES. Therefore, the containment air locks are not required in MODE 5 to prevent leakage of radioactive material from containment. The requirements for the containment air locks during MODE 6 are addressed in LCO 3.9.3, "Containment 10 Penetrations." 6 ACTIONS The ACTIONS are modified by a Note that allows entry and exit to If the inner 5 perform repairs on the affected air lock component. If the outer door is door is inoperable, inoperable, then it may be easily accessed for most repairs.

This changes the CTS by adding new Required Actions when the required RHR loop is inoperable. and Vent These added Required Actions are acceptable since they assist in minimizing the consequences of the required RHR loop being inoperable. Note that while CTS 3.8.b requires operations not be performed that could increase the reactivity of the core, this action is actually not required to be taken since once movement of fuel has been suspended, REFUELING OPERATIONS has ceased (thus, the LCO requirements of CTS 3.8.a are not required to be met). Thus, the addition of a similar Required Action (Required Action A.1), as well as the other above described Required Actions, is designated as more restrictive. | ||
M03 CTS 3.1.a.1.A does not contain any ACTIONS to take should there be less than the required number of RHR pumps in operation. As a result, CTS 3.0.c would normally be entered. However, LCO 3.0.c states that it is not applicable in COLD SHUTDOWN or REFUELING. Since the RHR pump only has to be in operation when a reduction in boron concentration is being made, and for this Specification, the unit is already in MODE 6, the CTS does not provide any compensatory measures. Therefore, 10 CFR 50.36 (c)(2)(i) would apply, which states to shutdown the unit. However, no times are provided to complete the shutdown and no further actions (i.e., suspend boron concentration reductions) are required. Note that while no ACTIONS are required, KPS in all likelihood would suspend dilution if this occurred. ITS 3.9.3 ACTION A specifies the Required Actions for a required RHR loop not in operation, and requires immediate suspension of operations that would cause introduction of coolant into the RCS with a boron concentration less than required to meet the boron concentration of LCO 3.9.1 (Required Action A.1), immediate suspension of loading irradiated fuel assemblies into the core (Required Action A.2), immediate initiation of action to restore one RHR loop to operation (Required Action A.3), | |||
closing the equipment hatch and securing it with four bolts in 4 hours (Required Action A.4), closing one door in each air lock in 4 hours (Required Action A.5), | |||
and a verification that each penetration providing direct access from the containment atmosphere to the outside atmosphere is either closed with a an OPERABLE manual or automatic isolation valve, blind flange, or equivalent, or is capable of being closed by a Containment Ventilation Isolation System in 4 hours (Required Action A.6). This changes the CTS by adding a new ACTION. | |||
Purge and Vent The purpose of the Actions should be to place the unit outside of the Applicability of the Specification. ITS 3.9.3 ACTION A effectively places the unit in an equivalent condition by requiring the plant to immediately suspend operations that would cause introduction of coolant into the RCS with a boron concentration less than required to meet the boron concentration of LCO 3.9.1 and to initiate action to restore one RHR loop to operation. The proposed Required Actions reflect the importance of maintaining operation for decay heat removal and boron mixing. This change is designated as more restrictive because a new proposed ACTION has been added. | |||

Consistent with TSTF-265, a Note is added to ITS SR 3.9.4.2 that permits the performance of the SR to verify correct breaker alignment and power availability to be delayed until 24 hours after a required RHR pump is not in operation. This provision is required because when RHR pumps are swapped under the current requirements, the Surveillance is immediately not met on the RHR pump taken out of operation. This change avoids entering an Action for a routine operational occurrence. The change is acceptable because adequate assurance exists that the RHR pump is aligned to the correct breaker with power available because, prior to being removed from operation, the applicable pump had been in operation. Allowing 24 hours to perform the breaker alignment verification is acceptable because the RHR pump was in operation, which demonstrated OPERABILITY, and because 24 hours is allowed in the ISTS by Kewaunee Power Station Page 1 of 2 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 181 of 208 | ||

Furthermore, SRs in Section 3.4 (ITS SRs 3.4.6.1, 3.4.7.1, and 3.4.8.1) require a similar verification that the RHR loop is in operation, but do not specify a flow rate requirement. This change is also consistent with the KPS current Technical Specifications, which does not specify a flow rate for the RHR loop. | |||

The purpose of the Containment Closure during Refueling requirements is to restrict the release of fission product radioactivity within containment from escaping to the environment following a fuel handling accident within the containment. The containment closure is not taken credit for in any accident analyses in the USAR. This is also documented in the NRC Safety Evaluation for License Amendment 190, dated March 8, 2007 (ADAMS Accession No. ML070430020). Therefore, the ITS does not include these Specifications. This changes the CTS by relocating the Containment Closure Specifications to the Technical Requirements Manual (TRM). | |||
This change is acceptable because CTS 3.8.a.1 and 3.8.a.8 do not meet the 10 CFR 50.36(c)(2)(ii) criteria for inclusion into the ITS. | |||
10 CFR 50.36(c)(2)(ii) Criteria Evaluation: | |||
: 1. Containment closure is not installed instrumentation that is used to detect, and indicate in the control room, a significant abnormal degradation of the reactor coolant pressure boundary. The Containment Closure Specifications do not satisfy criterion 1. | |||
: 2. Containment closure is not a process variable, design feature, or operating restriction that is in an initial condition of a DBA or Transient Analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. The Containment Closure Specifications do not satisfy criterion 2. | |||
: 3. Containment closure is not a structure, system, or component that is part of the primary success path and which functions or actuates to mitigate a DBA or Transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. The Containment Closure Specifications do not satisfy criterion 3. | |||
: 4. Containment closure was found to be non-significant risk contributor to core damage frequency and offsite releases. Dominion Energy Kewaunee (DEK) has performed a plant specific evaluation to ensure that the Containment Closure requirements do not contain constraints of prime importance in limiting the likelihood or severity of the accident Kewaunee Power Station Page 1 of 2 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 190 of 208 | |||

CTS 3.8.a.1 and 3.8.a.8 | Since the 10 CFR 50.36(c)(2)(ii) criteria have not been met, the Containment Closure Specifications (CTS 3.8.a.1 and 3.8.a.8) may be relocated out of the Technical Specifications. The containment closure specification will be relocated to the TRM. Changes to the TRM will be controlled by the provisions of 10 CFR 50.59. This change is designated as relocation because the specifications did not meet the criteria in 10 CFR 50.36(c)(2)(ii) and has been relocated to the TRM. | ||

Requested NRC Marked-up changes to CTS pages for several LCOs in ITS section 3.9, Question Refueling Operations, refer to same CTS LCO Condition instead of specifying the affected ITS LCO Condition. For example, a side note for CTS LCO Conditions 3.8.a.1a and b, (pl. refer to Attachment 1, Volume 14, Rev 0, Page 5 of 175), states, see CTS 3.8.a.1 and 3.8.a.8. The side note should have specified the affected ITS LCO Condition to which the CTS LCO Conditions 3.8.a.1a&b are relocated/converted. This concern also applies to side notes on the same page (page 5) for CTS LCO Conditions 3.8.a.2, 3.8.a.3, and note 1 (bottom of CTS page 3.8-1). Please note that marked changes on page 5 are also repeated on pages 25, 26, 27, 48, 49, 94, 95, 111, 112, 119, 126, 132, 139, and 147.
The staff believes that correct marked-up changes are necessary to perform a technical review of the subject ITS section.

Requested NRC Attachment 1, Volume 14, Rev. 0, Page 15 of 175 proposed ITS Bases Section B Question 3.9.1 A statement in ITS Bases Section B 3.9.1 (3rd paragraph) states, The Chemical and Volume Control System (CVCS) is the system capable of maintaining the reactor subcritical in cold conditions by maintaining the boron concentration.
KPS proposes to replace the statement with insert 1 on Page 16. However, the proposed insert does not specify a plant specific system for maintaining the boron concentration. KPS USAR section 1.3.5, Reactivity Control (GDC 27 - GDC 32), states, In addition to the reactivity control achieved by the RCC assemblies (RCCA) as detailed in Chapter 7, reactivity control is provided by the Chemical and Volume Control System which regulates the concentration of boric acid solution neutron absorber in the Reactor Coolant System.
Please explain the reason for deletion of the CVCS function from the Bases section.

Statement While the quoted information from USAR section 1.3.5 is correct, it is not the current and licensed requirement; it is the original FSAR requirement.
Specifically, on the first page of Section 1.3, a Note at the front of the Section states:
"NOTE: Section 1.3 provides original licensing and design basis information for the Kewaunee Plant as described in the facility license application Amendment No. 7 (the FSAR), dated January 27, 1971, and subsequent Amendments 8 through 20; and approved in the AEC Safety Evaluation issued July 24, 1972, and its supplements. This information was developed in support of plant licensing; therefore, this section is considered historical and should not be revised. Updated information can be found in the applicable section of the USAR."
For KPS GDC 27, this is found in USAR Section 3.1.2.3, as shown in the Reference Section of the ITS 3.9.1 Bases (Page 19). USAR Section 3.1.2.3 states as the Criterion: "Two independent reactivity control systems, preferably of different principles, shall be provided (GDC 27)." These are the words KPS inserted in lieu of the ISTS wording for 10 CFR 50, Appendix A, GDC 26.
KPS further noted that the ISTS wording stated that there were two independent reactivity control systems, but only one potential system, the Chemical and Volume Control System (CVCS), is identified in the paragraph. The main reactivity control system that is specified in the Technical Specifications, i.e., control rods, is not in the paragraph. KPS also reviewed the wording of 10 CFR 50, Appendix A, GDC 56 and noted that the ISTS wording does not match the GDC being referenced. The words in 10 CFR 50, Appendix A are:
"Criterion 26--Reactivity control system redundancy and capability. Two independent reactivity control systems of different design principles shall be provided. One of the systems shall use control rods, preferably including a positive means for inserting the rods, and shall be capable of reliably controlling reactivity changes to assure that under conditions of normal operation, including anticipated operational occurrences, and with appropriate margin for malfunctions such as stuck rods, specified Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 7 of 208 http://www.excelservices.com/rai/index.php?requestType=areaItemPrint&itemId=2371 06/07/2010
Kewaunee ITS Conversion Database Page 2 of 2 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 8 of 208 acceptable fuel design limits are not exceeded. The second reactivity control system shall be capable of reliably controlling the rate of reactivity changes resulting from planned, normal power changes (including xenon burnout) to assure acceptable fuel design limits are not exceeded. One of the systems shall be capable of holding the reactor core subcritical under cold conditions."
None of the words in 10 CFR 50, Appendix A use the CVCS by name.
Furthermore, the CVCS was deleted from the Technical Specifications and allowed to be placed in a document under utility control when the ISTS was originally issued. Thus, adding the name of a non-Technical Specification System into the Applicable Safety Analyses Bases could imply that the System needs to be in the Technical Specification.
Therefore, KPS does not believe that the CVCS should be mentioned in the Bases paragraph, and that the proposed words in the KPS submittal are correct and should be maintained as is.

Justification For Deviations (JFD) note 3 on page 59 states, ISTS 3.9.5 Required Actions A.6.1 and A.6.2 are connected by an "OR" logical connector, such that either one can be performed to meet the requirements of the ACTION. However, the two Required Actions are applicable to all the penetrations; either Required Action A.6.1 or Required Action A.6.2 must be performed for all the penetrations. Thus, this will not allow one penetration to be isolated by use of a manual valve and another penetration to be capable of being closed by an OPERABLE Containment Purge and Exhaust Isolation System. This is not the intent of the requirement. The requirement is based on ISTS LCO 3.9.4, which requires each penetration to be either: a) closed by a manual or automatic isolation valve, blind flange, or equivalent; or b) capable of being closed by an OPERABLE Containment Purge and Exhaust Isolation System. For consistency with the actual LCO requirement, ISTS 3.9.5 Required Actions A.6.1 and A.6.2 have been combined into a single Required Action in ITS 3.9.3 Required Action A.6.
Logical connectors are used in Technical Specifications (TS) to discriminate between, and yet connect, discrete Conditions, Required Actions, Completion Times, Surveillances, and Frequencies. The only logical connectors that appear in Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 10 of 208 http://www.excelservices.com/rai/index.php?requestType=areaItemPrint&itemId=1791 06/07/2010
Kewaunee ITS Conversion Database Page 2 of 2 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 11 of 208 TS are AND and OR. The physical arrangement of these connectors constitutes logical conventions with specific meanings. Required Actions A.6.1 and A.6.2 as specified in the TS, must be taken when the plant is in Condition A. These Actions as well as Completion Times for the Actions are not bracketed, and therefore plant specific changes are not acceptable. Revise the proposed ITS to incorporate the Required Actions and completion times of A.6.1 and A.6.2 per NUREG-1431, Revision 3. .

Response
Statement The purpose of ISTS 3.9.5 Required Actions A.4, A.5, A.6.1 and A.6.2, as stated in the ISTS Bases, is to ensure that all containment penetrations are either closed or can be closed so that the dose limits are not exceeded when the RHR loop requirements are not met. These actions come directly from the requirements of ISTS 3.9.3. With respect to the penetrations providing direct access from the containment atmosphere to the outside atmosphere, ISTS LCO 3.9.3.c (shown on Page 164 of Volume 14) requires that for each penetration, either it must be capable of being closed by a manual or automatic isolation valve, blind flange, or equivalent, or it must be capable of being closed by an OPERABLE Containment Purge and Exhaust Isolation System. Thus, ISTS LCO 3.9.3 allows either option for each of the penetrations; a single option does not have to be used for all of the penetrations.
ISTS 3.9.5 Required Actions A.6.1 and A.6.2 are written such that only one of these can be used for every single penetration. Either you have to meet Required Action A.6.1 for all the penetrations or you have to meet Required Action A.6.2 for all the penetrations. Obviously, a plant cannot meet Required Action A.6.2 for all the penetrations, since they all do not have automatic closure capability. The true intent of these two Required Actions is as stated in the ISTS Bases. The ISTS Bases for these two Required Actions (Page 64) are in the same paragraph and describes that each penetration must be closed by a manual or automatic isolation valve, blind flange, or equivalent, or verified to be capable of being closed by and OPERABLE Containment Purge and Exhaust Isolation System. Thus, for each penetration, you chose Required Action A.6.1 or A.6.2.
KPS has made a change to reflect what the requirements are in both ISTS LCO 3.9.3 and ISTS 3.9.5 Required Actions A.6.1 and A.6.2 Bases.
Adopting the ISTS 3.9.5 Required Actions A.6.1 and A.6.2 as written, without combining the two in a single Required Action, would force KPS to essentially use ISTS 3.9.5 Required Action A.6.1 at all times (since not all penetrations are capable of being closed by an automatic isolation system). This change has been previously reviewed and approved by the NRC during recent ITS conversions, like DC Cook Units 1 and 2 and Davis-Besse. Therefore, KPS believes that this change is only an editorial change to correct an inconsistency with the base requirement in ISTS Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 12 of 208 http://www.excelservices.com/rai/index.php?requestType=areaItemPrint&itemId=2481 06/07/2010

Statement The Kewaunee Power Station (KPS) CTS does not include any shutdown cooling minimum flow rate requirements while in MODE 6. KPS added SR 3.9.3.1 (and SR 3.9.4.1) as part of the ITS conversion. However, the minimum flow rate value was not included, as is stated in JFD 5. The JFD states that "The ISTS Bases states that the flow rate is determined by the flow rate necessary to provide sufficient decay heat removal capability.
However, the decay heat is not always the same; it is a function of time after shutdown and the power history of the fuel." Thus, there is no single value of shutdown cooling flow that will ensure decay heat is removed under all conditions. The JFD further states "Furthermore, SRs in Section 3.4 (ITS SRs 3.4.6.1, 3.4.7.1, and 3.4.8.1) require a similar verification that the RHR loop is in operation, but do not specify a flow rate requirement." In addition, KPS does not have RHR flow indication that could quantify the flow through the RHR heat exchanger (which is the flow removing the decay heat). The RHR flow meter is downstream of the connection where the heat exchanger discharge flow and heat exchanger bypass flow is merged. When in the shutdown cooling mode, some of the flow is going through the heat exchanger and some of the flow is bypassing the heat exchanger. Flow through the bypass is throttled to obtain the flow necessary to maintain RCS temperature at the desired value. However, the actual flow through the heat exchanger is not known, only the total RHR flow is known. USAR Figure 9.3-1, on page 9.3-27, provides a drawing of the RHR System (FT 626 is the flow instrument)
KPS believes that including a Surveillance to verify one RHR loop is in operation and circulating reactor coolant is sufficient to ensure the surveillance criteria of 10 CFR 50.36(c)(3) are met. Specifically, 10 CFR 50.36(c)(3) states that "Surveillance requirements are requirements relating to test, calibration, or inspection to assure that the necessary quality of systems and components is maintained, that facility operation will be within safety limits, and that the limiting conditions for operation will be met." SR 3.9.3.1 continues to ensure that this requirement is met, since there is no specific flow value in any safety limit. LCO 3.9.3 is required to ensure temperature is maintained to prevent boiling (as stated in the ASA section of the ISTS Bases), and this is met by having one RHR loop in operation and circulating coolant.

Statement KPS does not include the RHR flowrate in the KPS ITS SRs similar to several similar vintage PWRs (Point Beach, Prairie Island, and R.E. Ginna) which all have ITS. KPS does not have a specific analysis for boron and thermal stratification.
The Kewaunee Power Station reviewed boron and thermal stratification industry standards that were considered in the development of NUREG-1431.
As an industry, the fact that by license, RHR flow is maintained to the Reactor Coolant System while shutdown precludes that possibility of stratification. The one hour exception in the ISTS LCO 3.9.5 Note (KPS ITS LCO 3.9.3 Note) allows for stable water conditions during movement of components such as reactor internals. This is an accepted industry practice and an allowance already approved by the NRC. The ISTS Bases description of the Note does not discuss thermal stratification issues. It only provides compensatory measures to preclude boron concentration reduction during this 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> period.
Thermal and boron stratification do not occur with forced circulation as required by ITS. During MODE 6, temperatures are maintained well below boiling in the core with the water level above the core and temperature of the coolant at <140°F by procedure in the refueling cavity. Temperatures encountered in MODE 6 do not present a safety issue from thermal stratification since it is common industry practice to secure RHR for short periods of time. CTS requires RHR pumps to be OPERABLE, but does not specify a flow requirement.
Boron stratification is not a concern due to the fact that boron is soluble well above refueling concentrations that could possibly cause blockage of flow channels. WCAP 1570 solubility curves in water show that at 0 ºC boron is soluble to ~4800 ppm and at 20ºC boron is soluble to ~8000 ppm.
Also, when in MODE 6 with boron concentration within the limits of LCO 3.9.1, the possibility of a reactivity event is extremely remote. Diffusion of boron follows the rules of diffusion theory, thus there is low probability of varying concentrations of boron in the reactor coolant without flow.
Stratification is more of a post accident situation with a loss of coolant Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 20 of 208 http://www.excelservices.com/rai/index.php?requestType=areaItemPrint&itemId=2681 06/07/2010

[recently] irradiated fuel assemblies within containment. On page 166, KPS states that no credit is taken for the containment penetrations in the fuel handling accident analysis at KPS and since the Applicability of ISTS 3.9.4 is during movement of recently irradiated fuel assemblies within containment, the subject LCO is not included in KPS ITS.

Discussion:
As stated in the ITS Bases, fuel handling accidents, analyzed in Reference 3, include dropping a single irradiated fuel assembly and handling tool or a heavy object onto other irradiated fuel assemblies. The requirements of LCO 3.9.7, "Refueling Cavity Water Level," in conjunction with a minimum decay time of 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> prior to [irradiated fuel movement with containment closure capability or a minimum decay time of [x]
days without containment closure capability], ensures that the release of fission product radioactivity, subsequent to a fuel handling accident, results in doses that are well within the guideline values specified in 10 CFR 100.
Based on the above, please retain ITS LCO 3.9.4 for KPS ITS and specify of minimum decay time requirement in KPS ITS Bases to ensure the staff can conclude KPS TS ensure adequate protection of the public health and safety.

Add proposed SR 3.9.6.1 M01 Amendment No. 200 TS 3.8-2 11/20/2008 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 30 of 208 Page 2 of 2
Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 31 of 208 DISCUSSION OF CHANGES ITS 3.9.6, CONTAINMENT PENETRATIONS ADMINISTRATIVE CHANGES A01 In the conversion of the Kewaunee Power Station (KPS) Current Technical Specifications (CTS) to the plant specific Improved Technical Specifications (ITS), certain changes (wording preferences, editorial changes, reformatting, revised numbering, etc.) are made to obtain consistency with NUREG-1431, Rev. 3.0, "Standard Technical Specifications-Westinghouse Plants" (ISTS).
These changes are designated as administrative changes and are acceptable because they do not result in technical changes to the CTS.
A02 When the containment penetrations are not in the required condition specified in CTS 3.8.a.1 or CTS 3.8.a.8, CTS 3.8.b requires refueling of the reactor to cease, initiation of action to restore the containment penetrations to the required conditions, and no operations be performed that could increase the reactivity of the core. Under similar conditions, ITS 3.9.6 ACTION A only requires movement of irradiated fuel assemblies within containment to be suspended. This changes the CTS by deleting the requirements to initiate action to restore the containment penetrations to the required conditions and that no operations be performed that could increase the reactivity of the core.
The purpose of CTS 3.8.a.8 is to ensure proper compensatory actions are taken to exit the Applicability of the LCO. CTS 3.8.a.1 and 3.8.a.8 are only applicable during REFUELING OPERATIONS, which is defined in CTS Section 1.0 as the movement of reactor vessel internals that could affect the reactivity of the core within the containment when the vessel head is unbolted or removed. Thus, after the first requirement of CTS 3.8.b is met (i.e., suspend refueling the reactor), the Applicability has been exited and thus, continuation of the requirements of CTS 3.8.b are not required. Therefore, this change is acceptable and is designated as administrative since the technical requirements have not been changed.
MORE RESTRICTIVE CHANGES M01 CTS 3.8.a does not provide a Surveillance Requirement to verify each required containment penetration is in the required status. The ITS adds a Surveillance Requirement (SR 3.9.6.1) to verify each required containment penetration is in the required status once every 7 days. This changes the CTS by adding a new Surveillance Requirement for the containment penetrations.
This change is acceptable because the added Surveillance Requirement ensures that each required containment penetration is in the required status to support the containment penetration conditions assumed in the Fuel Handling Accident (FHA) analysis. In addition, this change is acceptable because the Surveillance Requirement continues to ensure that the structures, systems, and components are maintained consistent with the safety analyses and licensing basis. This change is designated as more restrictive because a new Surveillance Requirement has been added.

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 32 of 208 DISCUSSION OF CHANGES ITS 3.9.6, CONTAINMENT PENETRATIONS RELOCATED SPECIFICATIONS None REMOVED DETAIL CHANGES LA01 (Type 3 - Removing Procedural Details for Meeting TS Requirements or Reporting Requirements) CTS 3.8.a.1.a requires at least one door in each personnel air lock to be capable of being closed "within 30 minutes."
CTS 3.8.a.1.a is modified by a footnote (1) that states "Administrative controls ensure that appropriate personnel are aware that both personnel air lock doors are open; a specified individual(s) is designated and available to close the air lock following a required evacuation of containment; and, any obstruction(s) (e.g.,
cables and hoses) that could prevent closure of an open air lock can be quickly removed." ITS 3.9.6 does not contain this footnote information or the 30 minute requirement. This changes the CTS by moving the information contained in the footnote and the 30 minute requirement to the Bases.
The removal of these details, which are related to procedural details for meeting Technical Specification requirements, from the Technical Specifications is acceptable because this type of information is not necessary to be included in the Technical Specifications to provide adequate protection of public health and safety. The ITS still retains the requirement for at least one door in each personnel air lock to be capable of being closed. Also, this change is acceptable because the removed information will be adequately controlled in the ITS Bases.
Changes to the Bases are controlled by the Technical Specification Bases Control Program in Chapter 5. This program provides for the evaluation of changes to ensure the Bases are properly controlled. This change is designated as a less restrictive removal of detail change because information relating to procedural details for meeting Technical Specification requirements is being removed from the Technical Specifications.
LESS RESTRICTIVE CHANGES L01 (Category 1 - Relaxation of LCO Requirements) CTS 3.8.a.1.a, in part, requires at least one door in each personnel air lock to be closed when the reactor vessel head or upper internals are being lifted. ITS 3.9.6 does not include this requirement. This changes the CTS by not requiring one door in each personnel air lock to be closed when the reactor vessel head or upper internals are being lifted.
The purpose of CTS 3.8.a.1 is to ensure that if a fuel handling accident occurs, the release of any subsequent fission products results in doses that are well within the guideline values specified in Regulatory Guide 1.183. A fuel handling accident, as analyzed in USAR Section 14.2.1, is postulated to occur during handling of irradiated fuel assemblies; not handling the vessel head or upper internals. Thus, moving the vessel head or upper internals cannot result in a fuel handling accident. Any additional requirements, above those required to meet the assumptions of the fuel handling accident, are more appropriately controlled Kewaunee Power Station Page 2 of 5 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 32 of 208
Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 33 of 208 DISCUSSION OF CHANGES ITS 3.9.6, CONTAINMENT PENETRATIONS by plant procedures. Therefore, this change is acceptable and is designated a less restrictive change since the requirement to maintain containment closure capability during movement of the vessel head or upper internals is being deleted from the CTS.
L02 (Category 1 - Relaxation of LCO Requirements) CTS 3.8.a.1.b, in part, states that each line that penetrates containment and which provides a direct air path from containment atmosphere to the outside atmosphere shall have a closed isolation valve. ITS LCO 3.9.6.c.1 states that each penetration providing direct access from the containment atmosphere to the outside atmosphere is closed by a manual or automatic isolation valve, blind flange, or equivalent. This changes the CTS by specifying the use of a blind flange or an equivalent means of isolating a containment penetration.
The purpose of CTS 3.8.a.1 is to ensure the containment penetrations are in the condition assumed in the Fuel Handling Accident (FHA) analysis. This change is acceptable because the LCO requirements continue to ensure that the structures, systems, and components are maintained consistent with the safety analyses and licensing basis. The addition of the option to use a blind flange or some other equivalent means of isolating the containment penetration allows additional flexibility in the ITS that was not available in CTS. This change is designated as less restrictive because less stringent LCO requirements are being applied in the ITS than were applied in the CTS.
L03 (Category 1 - Relaxation of LCO Requirements) ITS LCO 3.9.6 Note states "Penetration flow path(s), except the equipment hatch, providing direct access from the containment atmosphere to the outside atmosphere may be unisolated under administrative controls." CTS 3.8.a does not include such an allowance.
This changes the CTS by allowing containment penetration flow paths to be unisolated under administrative controls during movement of irradiated fuel assemblies within containment.
The purpose of CTS 3.8.a.1 is to ensure the containment penetrations are in the condition assumed in the Fuel Handling Accident (FHA) analysis. This change is acceptable because the LCO requirements continue to ensure that the structures, systems, and components are maintained consistent with the safety analyses and licensing basis. The Reviewers Note in the ISTS LCO Bases associated with the LCO Note states that the allowance to have the personnel air lock doors open and the penetration flow paths unisolated under administrative control requires confirmatory dose calculations approved by the NRC staff and commitments from the licensee to implement acceptable administrative procedures to ensure that in the event of a refueling accident that the open penetration(s) can and will be promptly closed. The confirmatory dose calculations were made by the NRC as part of Amendment 166, dated 3/17/2003 (ADAMS Accession No. ML030210062) as modified by Amendment 190, dated 3/8/2007 (ADAMS Accession No. ML070430020). These Amendments revised the radiological consequence analyses for the KPS FHA to implement the Alternate Source Term. Kewaunee Power Station commits to implementing administrative procedures to ensure that in the event of a refueling accident, the open air locks and open penetration(s) can and will be promptly closed.

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 34 of 208 DISCUSSION OF CHANGES ITS 3.9.6, CONTAINMENT PENETRATIONS change is designated as less restrictive because less stringent LCO requirements are being applied in the ITS than were applied in the CTS.
L04 (Category 6 - Relaxation Of Surveillance Requirement Acceptance Criteria)
CTS 3.8.a.8 requires verification of the automatic actuation of the Containment Ventilation and Purge valves on a containment ventilation isolation signal. ITS SR 3.9.6.2 specifies that the signal may be from either an actual or simulated signal. This changes the CTS by explicitly allowing the use of either an actual or simulated signal to perform the Surveillance.
The purpose of CTS 3.8.a.8 is to ensure that the containment purge and vent valves operate correctly upon receipt of an actuation signal. This change is acceptable because it has been determined that the relaxed Surveillance Requirement acceptance criteria are not necessary for verification that the equipment used to meet the LCO can perform its required functions. Equipment cannot discriminate between an "actual," "simulated," or "test" signal and, therefore, the results of the testing are unaffected by the type of signal used to initiate the test. This change allows taking credit for unplanned actuation if sufficient information is collected to satisfy the Surveillance test requirements.
The change also allows a simulated signal to be used, if necessary. This change is designated as less restrictive because less stringent Surveillance Requirements are being applied in the ITS than were applied in the CTS.
L05 (Category 7 - Relaxation Of Surveillance Frequency) CTS 3.8.a.8 includes a Surveillance Frequency of "immediately prior to and daily during REFUELING OPERATIONS" for performing a Surveillance of the Containment Ventilation and Purge System. The ITS SR 3.9.6.2 Frequency for the same requirement is 18 months. ITS SR 3.9.6.2 is also modified by a Note that states that SR 3.9.6.2 is not required to be met for containment purge and vent valve(s) in penetrations that are closed to comply with LCO 3.9.6.c.1. This changes the CTS by changing the Surveillance Frequency from immediately prior to and daily during REFUELING OPERATIONS to 18 months and adding the Note that the SR is not required to be met for containment purge and vent valve(s) in penetrations that are closed to comply with ITS LCO 3.9.6.c.1.
The purpose of CTS 3.8.a.8 is to verify the equipment required to meet the LCO is OPERABLE. This change is acceptable because the new Surveillance Frequency has been evaluated to ensure that it provides an acceptable level of equipment reliability. Containment purge and vent valve testing is still required, but at a Frequency consistent with the testing Frequency for containment isolation valves required in MODES 1, 2, 3, and 4. This Frequency provides an appropriate degree of assurance that the valves are OPERABLE. When containment purge and vent valve(s) in penetrations are closed to comply with ITS LCO 3.9.6.c.1, the penetrations are in the expected condition (isolated) to mitigate the effects of a fuel handling accident inside containment. Therefore, there is no need for the actuation signal to reposition the valves to the closed position. This change is designated as less restrictive because Surveillances will be performed less frequently under the ITS than under the CTS.
L06 (Category 1 - Relaxation of LCO Requirements) CTS 3.8.a specifies that the CTS 3.8.a.1 containment closure requirements are applicable during Kewaunee Power Station Page 4 of 5 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 34 of 208

ITS 3.9.6 is applicable during movement of irradiated fuel assemblies within containment.
This changes the CTS by not requiring the containment closure requirements to be met when moving or handling control rods during MODE 6 operation.
The purpose of CTS 3.8.a.1 is to ensure that if a fuel handling accident occurs, the release of any subsequent fission products results in doses that are well within the guideline values specified in Regulatory Guide 1.183. A fuel handling accident, as analyzed in USAR Section 14.2.1, can only occur during handling of irradiated fuel assemblies; not moving or handling control rods (which are the only other reactor vessel internals currently in use at KPS that could affect reactivity of the core). Thus, moving or handling the control rods cannot result in a fuel handling accident. Any additional requirements, above those required to meet the assumptions of the fuel handling accident, are more appropriately controlled by plant procedures. Therefore, this change is acceptable and is designated a less restrictive change since the requirement to maintain containment closure capability during movement or handling of control rods in MODE 6 is being deleted from the CTS.

BASES BACKGROUND During movement of [recently] irradiated fuel assemblies within containment, a release of fission product radioactivity within containment will be restricted from escaping to the environment when the LCO requirements are met. In MODES 1, 2, 3, and 4, this is accomplished by maintaining containment OPERABLE as described in LCO 3.6.1, "Containment." In MODE 6, the potential for containment pressurization as a result of an accident is not likely; therefore, requirements to isolate the containment from the outside atmosphere can be less stringent. The LCO requirements are referred to as "containment closure" rather than "containment OPERABILITY." Containment closure means that all potential escape paths are closed or capable of being closed. Since there is no potential for containment pressurization, the Appendix J leakage criteria and tests are not required.
The containment serves to contain fission product radioactivity that may be released from the reactor core following an accident, such that offsite radiation exposures are maintained well within the requirements of guidance 2 Regulatory Guide 1.183 (Ref. 1) 10 CFR 100. Additionally, the containment provides radiation shielding from the fission products that may be present in the containment atmosphere following accident conditions.
The containment equipment hatch, which is part of the containment pressure boundary, provides a means for moving large equipment and components into and out of containment. During movement of [recently]
irradiated fuel assemblies within containment, the equipment hatch must be held in place by at least four bolts. Good engineering practice dictates that the bolts required by this LCO be approximately equally spaced.
The containment air locks, which are also part of the containment pressure boundary, provide a means for personnel access during MODES 1, 2, 3, and 4 unit operation in accordance with LCO 3.6.2, "Containment Air Locks." Each air lock has a door at both ends. The doors are normally interlocked to prevent simultaneous opening when containment OPERABILITY is required. During periods of unit shutdown when containment closure is not required, the door interlock mechanism may be disabled, allowing both doors of an air lock to remain open for extended periods when frequent containment entry is necessary.
During movement of [recently] irradiated fuel assemblies within containment, containment closure is required; therefore, the door interlock mechanism may remain disabled, but one air lock door must always remain [capable of being] closed.

BASES TSTF-471-A APPLICABLE During CORE ALTERATIONS or movement of irradiated fuel assemblies SAFETY within containment, the most severe radiological consequences result ANALYSES from a fuel handling accident [involving handling recently irradiated fuel].
The fuel handling accident is a postulated event that involves damage to 2 irradiated fuel (Ref. 2). Fuel handling accidents, analyzed in Reference 3, 2 vertically onto a rigid surface or include dropping a single irradiated fuel assembly and handling tool or a heavy object onto other irradiated fuel assemblies. The requirements of 5 LCO 3.9.7, "Refueling Cavity Water Level," in conjunction with a minimum 7 decay time of 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> prior to [irradiated fuel movement with containment closure capability or a minimum decay time of [x] days Regulatory Guide 1.183 without containment closure capability], ensures that the release of fission (Ref. 1) product radioactivity, subsequent to a fuel handling accident, results in 2
doses that are well within the guideline values specified in 10 CFR 100.
Standard Review Plan, Section 15.7.4, Rev. 1 (Ref. 3), defines "well within" 10 CFR 100 to be 25% or less of the 10 CFR 100 values. The 2
acceptance limits for offsite radiation exposure will be 25% of 10 CFR 100 values or the NRC staff approved licensing basis (e.g., a specified fraction of 10 CFR 100 limits).
Containment penetrations satisfy Criterion 3 of 10 CFR 50.36(c)(2)(ii).
LCO -----------------------------------REVIEWERS NOTE-----------------------------------
The allowance to have containment personnel air lock doors open and TSTF-471-A penetration flow paths with direct access from the containment atmosphere to the outside atmosphere to be unisolated during fuel movement and CORE ALTERATIONS is based on (1) confirmatory dose calculations of a fuel handling accident as approved by the NRC staff which indicate acceptable radiological consequences and 3 (2) commitments from the licensee to implement acceptable administrative procedures that ensure in the event of a refueling accident (even though the containment fission product control function is not required to meet acceptable dose consequences) that the open air lock can and will be promptly closed following containment evacuation and that the open penetration(s) can and will be promptly closed. The time to close such penetrations or combination of penetrations shall be included in the confirmatory dose calculations.
This LCO limits the consequences of a fuel handling accident [involving 2 handling recently irradiated fuel] in containment by limiting the potential escape paths for fission product radioactivity released within containment.
The LCO requires any penetration providing direct access from the containment atmosphere to the outside atmosphere to be closed except for the OPERABLE containment purge and exhaust penetrations [and the 2 vent containment personnel air locks].

The OPERABILITY requirements for this LCO ensure 2 that the automatic purge and exhaust valve closure times specified in the FSAR can be achieved and, therefore, meet the assumptions used in the safety analysis to ensure that releases through the valves are terminated, such that radiological doses are within the acceptance limit.
, except the The LCO is modified by a Note allowing penetration flow paths with direct equipment 8 hatch, access from the containment atmosphere to the outside atmosphere to be unisolated under administrative controls. Administrative controls ensure that 1) appropriate personnel are aware of the open status of the TSTF-471-A penetration flow path during CORE ALTERATIONS or movement of irradiated fuel assemblies within containment, and 2) specified individuals are designated and readily available to isolate the flow path in the event 2 of a fuel handling accident.

Should a fuel handling accident occur inside containment, one 2 personnel air lock door will be closed following an evacuation of containment.
APPLICABILITY The containment penetration requirements are applicable during 1
movement of [recently] irradiated fuel assemblies within containment because this is when there is a potential for the limiting fuel handling accident. In MODES 1, 2, 3, and 4, containment penetration requirements are addressed by LCO 3.6.1. In MODES 5 and 6, when movement of irradiated fuel assemblies within containment is not being conducted, the potential for a fuel handling accident does not exist.
[Additionally, due to radioactive decay, a fuel handling accident involving handling recently irradiated fuel (i.e., fuel that has occupied part of a 1 critical reactor core within the previous [x] days) will result in doses that are well within the guideline values specified in 10 CFR 100 even without containment closure capability.] Therefore, under these conditions no requirements are placed on containment penetration status.

REVIEWERS NOTE-----------------------------------
The addition of the term "recently" associated with handling irradiated fuel in all of the containment function Technical Specification requirements is only applicable to those licensees who have demonstrated by analysis that after sufficient radioactive decay has occurred, off-site doses resulting from a fuel handling accident remain below the Standard Review Plan limits (well within 10 CFR 100).
Additionally, licensees adding the term "recently" must make the following commitment which is consistent with NUMARC 93-01, Revision 4, Section 11.3.6.5 "Safety Assessment for Removal of Equipment from Service During Shutdown Conditions," subheading "Containment -
Primary (PWR)/Secondary (BWR)."
"The following guidelines are included in the assessment of systems removed from service during movement irradiated fuel:
3
- During fuel handling/core alterations, ventilation system and radiation monitor availability (as defined in NUMARC 91-06) should be assessed, with respect to filtration and monitoring of releases from the fuel. Following shutdown, radioactivity in the fuel decays away fairly rapidly. The basis of the Technical Specification OPERABILITY amendment is the reduction in doses due to such decay. The goal of maintaining ventilation system and radiation monitor availability is to reduce doses even further below that provided by the natural decay.
- A single normal or contingency method to promptly close primary or secondary containment penetrations should be developed. Such prompt methods need not completely block the penetration or be capable of resisting pressure.
The purpose of the "prompt methods" mentioned above are to enable ventilation systems to draw the release from a postulated fuel handling accident in the proper direction such that it can be treated and monitored."

vent on the open purge and exhaust valves will demonstrate that the valves are not blocked from closing. Also the Surveillance will demonstrate that each valve operator has motive power, which will ensure that each valve is capable of being closed by an OPERABLE automatic containment purge and exhaust isolation signal.
The Surveillance is performed every 7 days during movement of [recently] 1 irradiated fuel assemblies within containment. The Surveillance interval is selected to be commensurate with the normal duration of time to complete fuel handling operations. A surveillance before the start of refueling operations will provide two or three surveillance verifications during the applicable period for this LCO. As such, this Surveillance ensures that a postulated fuel handling accident [involving handling 1 recently irradiated fuel] that releases fission product radioactivity within the containment will not result in a release of significant fission product radioactivity to the environment in excess of those recommended by Regulatory Guide 1.183 Standard Review Plan Section 15.7.4 (Reference 3). 2 1

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 56 of 208 Appendix A - Justification For Specification Relocation 3.8.a.1: Containment Closure Page Blank 3.8.a.8: Containment Closure DISCUSSION:
CTS 3.8.a.1 and 3.8.a.8 provide requirements for Containment Closure during refueling operations.
The purpose of the Containment Closure during Refueling requirements is to restrict the release of fission product radioactivity within containment from escaping to the environment following a fuel handling accident within the containment.
COMPARISON TO SCREENING CRITERIA:
- 1. Containment closure is not installed instrumentation that is used to detect, and indicate in the control room, a significant abnormal degradation of the reactor coolant pressure boundary.
- 2. Containment closure is not a process variable, design feature, or operating restriction that is in an initial condition of a DBA or Transient Analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier.
- 3. Containment closure is not a structure, system, or component that is part of the primary success path and which functions or actuates to mitigate a DBA or Transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier.
- 4. Containment closure was found to be non-significant risk contributor to core damage frequency and offsite releases.
CONCLUSION:
Since the screening criteria have not been satisfied, the Containment Closure Specifications may be relocated to other plant controlled documents outside Technical Specifications.

The ITS still retains the requirement for the Containment Purge and Vent Isolation Instrumentation be OPERABLE and specifies the number of required channels. Also, this change is acceptable because the removed information will be adequately controlled in the ITS Bases. Changes to the Bases are controlled by the Technical Specification Bases Control Program in ITS Chapter 5. This program provides for the evaluation of changes to ensure the Bases are properly controlled. This change is designated as a less restrictive removal of detail change because information relating system design is being removed from the Technical Specifications.
LESS RESTRICTIVE CHANGES L01 (Category 4 - Relaxation of Required Action) When both Containment Isolation Manual channels are inoperable, CTS Table TS 3.5-4 Column 6 requires the unit to be placed in HOT SHUTDOWN (ITS MODE 3). Under similar conditions, Not ITS 3.3.6 Required Action B.1 requires immediately entering the applicable used.
Conditions and Required Actions for the containment purge and vent isolation valves made inoperable by isolation instrumentation. This changes the CTS by allowing the actions for inoperable containment purge and vent valves to be taken when both Manual initiation channels are inoperable in lieu of shutting down the unit.
The purpose of the CTS Table TS 3.5-4 Column 6 action is to provide compensatory actions when both Manual Initiation channels are inoperable.
However, the CTS action is overly conservative in that it requires more restrictive actions than are allowed if the valves themselves were inoperable. The purpose of the instrumentation is to isolate the associated valves. Thus, this change is acceptable since the proposed ITS Required Action would accomplish this action (since ITS 3.6.3 would require isolation of the associated penetration flow path).
This change is designated as less restrictive since the proposed Required Action will allow operation to continue with the associated flow path isolated in lieu of shutting down the unit.

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 67 of 208 L02 (Category 2 - Relaxation of Applicability) CTS 3.8.a.1.b requires an OPERABLE automatic isolation valve under certain conditions. This is referring to the Containment Purge and Vent System valves, and thus includes the instruments that provide the isolation signal. The Specification is applicable during REFUELING OPERATIONS. This requirement can be met by an OPERABLE automatic isolation valve or a closed isolation valve. When this requirement is not being met, CTS 3.8.b provides actions to be taken if any of the specified limiting conditions in CTS 3.8 a are not met during REFUELING OPERATIONS. ITS 3.3.6 is applicable, in part, during movement of irradiated fuel assemblies within containment, as stated in footnote (a) to Table 3.3.6-1. This changes the CTS by requiring the containment purge and vent isolation instrumentation be OPERABLE during times of movement of irradiated fuel assemblies within containment, in lieu of during REFUELING OPERATIONS.
The purpose of CTS 3.8.a.1.b is to ensure each line that penetrates containment and provides a direct air path from containment atmosphere to the outside atmosphere have a closed isolation valve or an OPERABLE automatic isolation valve. Continuous monitoring of the radiation levels of the containment atmosphere (general or exhaust vent) is required to provide automatic action during an unsafe condition as a result of a fuel handling accident. CTS 3.8.a.1.b requires an OPERABLE automatic isolation valve during REFUELING OPERATIONS, and includes the isolation instrumentation. As defined in CTS Section 1.0, REFUELING OPERATIONS is movement of reactor vessel internal components that could affect the reactivity of the core within the containment when the vessel head is unbolted or removed. This would include both moving irradiated fuel assemblies and control rods. Since movement of irradiated fuel assemblies within containment can only occur when the vessel head is unbolted or removed, ITS 3.3.6 is applicable, with respect to moving fuel assemblies, under the same conditions as CTS 3.8.a.1.b. This change is acceptable because the requirements continue to ensure that the process variables are maintained in the MODES and other specified conditions assumed in the safety analyses and licensing basis. The fuel handling accident is based on damaging a single irradiated fuel assembly. Movement of control rods is not assumed to result in a fuel handling accident. This change is designated as less restrictive because the LCO requirements are applicable in fewer operating conditions than in the CTS.
L03 (Category 4 - Relaxation of Required Action) CTS 3.8.a.1.b requires an OPERABLE automatic isolation valve under certain conditions. This is referring to the Containment Purge and Vent System valves, and thus includes the instruments that provide the isolation signal. The Specification is applicable during REFUELING OPERATIONS.
When this requirement is not being met, the isolation valve must be closed or CTS 3.8.b requires refueling of the reactor to cease, initiation of action to restore the monitoring capability, and no operations be performed that could increase the reactivity of the core.
Under similar conditions, ITS 3.3.6 does not require the refueling of the reactor to cease or require all operations that could increase the reactivity of the core to cease. With one radiation monitoring channel inoperable, ITS 3.3.6 ACTION A requires restoration of the affected channel to OPERABLE status within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />. ITS 3.3.6 ACTION C, which is Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 67 of 208
Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 68 of 208 only applicable during the movement of irradiated fuel assemblies within containment, requires immediately placing and maintaining containment purge and vent valves in the closed position (Required Action C.1) or immediately entering the applicable Conditions and Required Actions of LCO 3.9.6 for containment purge and vent valves made inoperable by isolation instrumentation (Required Action C.2). Note that under this condition ITS LCO 3.9.6 would require suspension of movement of irradiated fuel assemblies in containment. This changes the CTS by deleting the requirements to cease refueling of the reactor and that no operations be performed that could increase the reactivity of the core and provides new ACTIONS to restore the radiation monitors to service and maintain the containment boundary.
The purpose of CTS 3.8.a.1.b is to ensure the Containment Purge and Vent System is OPERABLE to provide automatic actuation of the valves if an unsafe condition as a result of a fuel handling accident occurs or the valves are closed. CTS 3.8.b requires compensatory actions be taken to exit the Applicability of the LCO if continuous monitoring is not available and the isolation valves cannot be closed; however, the CTS Actions are overly restrictive. The proposed compensatory actions of ITS 3.3.6 ACTIONS A and C ensure that acceptable actions are taken when radiation channels are inoperable. The proposed ACTION A is acceptable since channels are still available to ensure the containment purge and vent valve receive an isolation signal. The proposed ACTION C is acceptable since when multiple channels are inoperable, the proposed action places the containment purge and vent valves in the isolated position, which performs the function of the radiation channels. This change is designated as less restrictive since less restrictive actions have been added for when the radiation channels are inoperable.

Time of Condition A (i.e., one radiation monitor is inoperable) is not met in MODES 1, 2, 3, and 4. ISTS 3.3.6 ACTION C provides the actions when two or more radiation monitoring channels are inoperable or when the Required Action and associated Completion Time of Condition A is not met during movement of recently irradiated fuel assemblies within containment. ISTS 3.3.6 ACTION C requires immediately placing and maintaining containment purge and exhaust valves in the closed position or to immediately enter the applicable Conditions and Required Actions of LCO 3.9.4, "Containment Penetrations," for containment purge and exhaust isolation valves made inoperable by isolation instrumentation. Kewaunee Power Station (KPS) does not credit containment isolation in a fuel handling accident analysis in the USAR. Therefore, ITS 3.3.6 does not maintain the applicability of during movement of recently irradiated fuel assemblies within containment as part of the Applicability. Therefore, all requirements related to movement of irradiated fuel assemblies in the containment (Table 3.3.6-1 Footnote (a) and ACTION C) have been deleted. In addition, due to this deletion, the Note to Condition B has been deleted since it is not necessary (there are no Actions other than those for MODES 1, 2, 3, and 4).
- 4. The ISTS contains a Surveillance Requirement (SR) for an ACTUATION LOGIC TEST (ISTSSR 3.3.6.2) for the Containment Purge and Vent Isolation Instrumentation that is performed every 31 days on a STAGGERED TEST BASIS.
The ISTS also contains an ACTUATION LOGIC TEST (ISTS SR 3.3.6.4) for the Containment Purge and Vent Isolation Instrumentation that is performed every 92 days on a STAGGERED TEST BASIS. ISTS SR 3.3.6.4 was added to the ISTS as part of the incorporation of TSTF-411, which, in part, increases the surveillance test interval (STI) for the actuation logic and actuation relays. The basis for the increase in the STI is WCAP-15376-P, Revision 0, which is consistent with the Nuclear Regulatory Commission's (NRC) approach for using probabilistic risk assessment in risk-informed decisions on plant-specific changes to the current licensing basis as presented in Regulatory Guides 1.174, "An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Current Licensing Basis," and 1.177, "An Approach for Plant-Specific, Risk-Informed Decisionmaking: Technical Specifications." KPS has elected to adopt the specific ISTS changes authorized by the results of WCAP-15376-P Revision 0. Therefore, the bracketed ISTS SR 3.3.6.4 (ITS SR 3.3.6.2) has been adopted for testing of the actuation logic and actuation relays.
Subsequent Surveillance Requirements have been renumbered as a result of not including ISTS SR 3.3.6.2 in the ITS.

- 1. Manual Initiation The LCO requires two channels OPERABLE. The operator can initiate Containment Purge Isolation at any time by using either of two switches in the control room. Either switch actuates both trains. This action will cause actuation of all components in the same manner as 4 any of the automatic actuation signals.
The LCO for Manual Initiation ensures the proper amount of redundancy is maintained in the manual actuation circuitry to ensure the operator has manual initiation capability.
Each channel consists of one push button and the interconnecting wiring to the actuation logic cabinet.

Compliance with this LCO will ensure a containment configuration, including equipment hatches, that is structurally sound and that will limit Note that while the Background section leakage to those leakage rates assumed in the safety analysis. 6 describes the Shield Building, the Shield Building requirements Individual leakage rates specified for the containment air lock (LCO 3.6.2) 9 are not covered by this LCO; they are provided
[, purge valves with resilient seals, and secondary bypass leakage combined in LCO 3.6.8, "Shield (LCO 3.6.3)] are not specifically part of the acceptance criteria of Building."
10 CFR 50, Appendix J. Therefore, leakage rates exceeding these individual limits only result in the containment being inoperable when the leakage results in exceeding the overall acceptance criteria of 1.0 La.
APPLICABILITY In MODES 1, 2, 3, and 4, a DBA could cause a release of radioactive material into containment. In MODES 5 and 6, the probability and consequences of these events are reduced due to the pressure and temperature limitations of these MODES. Therefore, containment is not required to be OPERABLE in MODE 5 to prevent leakage of radioactive material from containment. The requirements for containment during MODE 6 are addressed in LCO 3.9.4, "Containment Penetrations." 11 3
ACTIONS A.1 6 In the event containment is inoperable, containment must be restored to OPERABLE status within 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br />. The 1 hour1.157407e-5 days <br />2.777778e-4 hours <br />1.653439e-6 weeks <br />3.805e-7 months <br /> Completion Time provides a period of time to correct the problem commensurate with the importance of maintaining containment OPERABLE during MODES 1, 2, 3, and 4.
This time period also ensures that the probability of an accident (requiring containment OPERABILITY) occurring during periods when containment is inoperable is minimal.
B.1 and B.2 If containment cannot be restored to OPERABLE status within the required Completion Time, the plant must be brought to a MODE in which the LCO does not apply. To achieve this status, the plant must be brought to at least MODE 3 within 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> and to MODE 5 within 36 hours4.166667e-4 days <br />0.01 hours <br />5.952381e-5 weeks <br />1.3698e-5 months <br />.

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 78 of 208 Containment Air Locks (Atmospheric, Subatmospheric, Ice Condenser, and Dual) 1 B 3.6.2 BASES APPLICABLE SAFETY ANALYSES (continued) B 2 8 10 CFR 50, Appendix J, Option A (Ref. 1), as La = [0.1]% of containment air weight per day, the maximum allowable containment leakage rate at the calculated peak containment internal pressure Pa = [14.4] psig 8 following a design basis LOCA. This allowable leakage rate forms the basis for the acceptance criteria imposed on the SRs associated with the air locks.
The containment air locks satisfy Criterion 3 of 10 CFR 50.36(c)(2)(ii).
LCO Each containment air lock forms part of the containment pressure boundary. As part of the containment pressure boundary, the air lock safety function is related to control of the containment leakage rate resulting from a DBA. Thus, each air lock's structural integrity and leak tightness are essential to the successful mitigation of such an event.
Each air lock is required to be OPERABLE. For the air lock to be considered OPERABLE, the air lock interlock mechanism must be OPERABLE, the air lock must be in compliance with the Type B air lock leakage test, and both air lock doors must be OPERABLE. The interlock allows only one air lock door of an air lock to be opened at one time. This provision ensures that a gross breach of containment does not exist when containment is required to be OPERABLE. Closure of a single door in each air lock is sufficient to provide a leak tight barrier following postulated events. Nevertheless, both doors are kept closed when the air lock is not being used for normal entry into or exit from containment.
APPLICABILITY In MODES 1, 2, 3, and 4, a DBA could cause a release of radioactive material to containment. In MODES 5 and 6, the probability and consequences of these events are reduced due to the pressure and temperature limitations of these MODES. Therefore, the containment air locks are not required in MODE 5 to prevent leakage of radioactive material from containment. The requirements for the containment air locks during MODE 6 are addressed in LCO 3.9.3, "Containment 10 Penetrations." 6 ACTIONS The ACTIONS are modified by a Note that allows entry and exit to If the inner 5 perform repairs on the affected air lock component. If the outer door is door is inoperable, inoperable, then it may be easily accessed for most repairs. It is then preferred that the air lock be accessed from inside primary containment by entering through the other OPERABLE air lock. However, if this is not practicable, or if repairs on either door must be performed from the barrel side of the door then it is permissible to enter the air lock through the OPERABLE door, which means there is a short time during which the containment boundary is not intact (during access through the WOG STS B 3.6.2-2 Rev. 3.0, 03/31/04 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 78 of 208

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 83 of 208 DISCUSSION OF CHANGES ITS 3.9.3, RHR AND COOLANT CIRCULATION - HIGH WATER LEVEL verification that each penetration providing direct access from the containment atmosphere to the outside atmosphere is either closed with a manual or an OPERABLE automatic isolation valve, blind flange, or equivalent, or is capable of being closed by a Containment Ventilation and Purge Isolation System in 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> (Required Action A.6). This changes the CTS by adding new Required Actions when the required RHR loop is inoperable. and Vent These added Required Actions are acceptable since they assist in minimizing the consequences of the required RHR loop being inoperable. Note that while CTS 3.8.b requires operations not be performed that could increase the reactivity of the core, this action is actually not required to be taken since once movement of fuel has been suspended, REFUELING OPERATIONS has ceased (thus, the LCO requirements of CTS 3.8.a are not required to be met). Thus, the addition of a similar Required Action (Required Action A.1), as well as the other above described Required Actions, is designated as more restrictive.
M03 CTS 3.1.a.1.A does not contain any ACTIONS to take should there be less than the required number of RHR pumps in operation. As a result, CTS 3.0.c would normally be entered. However, LCO 3.0.c states that it is not applicable in COLD SHUTDOWN or REFUELING. Since the RHR pump only has to be in operation when a reduction in boron concentration is being made, and for this Specification, the unit is already in MODE 6, the CTS does not provide any compensatory measures. Therefore, 10 CFR 50.36 (c)(2)(i) would apply, which states to shutdown the unit. However, no times are provided to complete the shutdown and no further actions (i.e., suspend boron concentration reductions) are required. Note that while no ACTIONS are required, KPS in all likelihood would suspend dilution if this occurred. ITS 3.9.3 ACTION A specifies the Required Actions for a required RHR loop not in operation, and requires immediate suspension of operations that would cause introduction of coolant into the RCS with a boron concentration less than required to meet the boron concentration of LCO 3.9.1 (Required Action A.1), immediate suspension of loading irradiated fuel assemblies into the core (Required Action A.2), immediate initiation of action to restore one RHR loop to operation (Required Action A.3),

Purge and Vent The purpose of the Actions should be to place the unit outside of the Applicability of the Specification. ITS 3.9.3 ACTION A effectively places the unit in an equivalent condition by requiring the plant to immediately suspend operations that would cause introduction of coolant into the RCS with a boron concentration less than required to meet the boron concentration of LCO 3.9.1 and to initiate action to restore one RHR loop to operation. The proposed Required Actions reflect the importance of maintaining operation for decay heat removal and boron mixing. This change is designated as more restrictive because a new proposed ACTION has been added.

However, the two Required Actions are applicable to all the penetrations; either Required Action A.6.1 or Required Action A.6.2 must be performed for all the penetrations. Thus, this will not allow one penetration to be isolated by use of a manual valve and another penetration to be capable of being closed by an OPERABLE Containment Purge and Exhaust Isolation System. This is not the intent of the requirement. The requirement is based on ISTS LCO 3.9.4, which requires each penetration to be either: a) closed by a manual or automatic isolation valve, blind flange, or equivalent; or b) capable of being closed by an OPERABLE Containment Purge and Exhaust Isolation System. For consistency with the actual LCO requirement, ISTS 3.9.5 Required Actions A.6.1 and A.6.2 have been combined into a single Required Action in ITS 3.9.3 Required Action A.6.

- 5. The minimum required RHR flow rate requirement has not been included in KPS ITS SR 3.9.3.1. The Bases states that the flow rate is determined by the flow rate necessary to provide sufficient decay heat removal capability. However, the decay heat is not always the same; it is a function of time after shutdown and the power history of the fuel. Furthermore, SRs in Section 3.4 (ITS SRs 3.4.6.1, 3.4.7.1, and 3.4.8.1) require a similar verification that the RHR loop is in operation, but do not specify a flow rate requirement. This change is also consistent with the KPS current Technical Specifications, which does not specify a flow rate for the RHR loop.

This changes the CTS by adding a new ACTION when both required RHR loops are inoperable.
The change is acceptable because the Completion Times are consistent with safe operation under the specified Condition, considering the OPERABLE status of the redundant systems or features, a reasonable time for repairs or replacement, and the low probability of a DBA occurring during the allowed Completion Times. The immediate initiation of action to restore the required loops to OPERABLE status or to establish 23 ft of water above the top of the reactor vessel flange reflects the importance of maintaining operation for decay heat removal. This change is designated as more restrictive because a new ACTION is being added to the ITS that was not required by the CTS.

This changes the CTS by adding a new ACTION. Purge and Vent The purpose of the Actions should be to place the unit outside of the Applicability of the Specification. ITS 3.9.4 ACTION B effectively places the unit in an equivalent condition by requiring the plant to immediately suspend operations that would cause introduction of coolant into the RCS with a boron concentration less than required to meet the boron concentration of LCO 3.9.1 and to initiate action to restore one RHR loop to operation. The proposed Required Actions reflect the importance of maintaining operation for decay heat removal and boron mixing. This change is designated as more restrictive because a new proposed ACTION has been added.

- 1. The term "train" in ISTS 3.9.6 LCO Note 1 has been changed to "loop" to be consistent with the actual LCO statement, which requires loops to be OPERABLE and in operation, not trains. In addition, the term "degrees" has been replaced with the unit designator "º" consistent with its use throughout the ISTS (see ISTS LCO 3.4.6, 3.4.7, and 3.4.8 Note 1).
- 2. The punctuation corrections have been made consistent with the Writer's Guide for the Improved Standard Technical Specifications, TSTF-GG-05-01, Section 5.1.3.

- 4. Typographical error corrected.
- 5. The ISTS contains bracketed information and/or values that are generic to all Westinghouse vintage plants. The brackets are removed and the proper plant specific information/value is provided. This is acceptable since the generic specific information/value is revised to reflect the current plant requirements.
- 6. ISTS 3.9.6 Required Actions B.5.1 and B.5.2 are connected by an "OR" logical connector, such that either one can be performed to meet the requirements of the ACTION. However, the two Required Actions are applicable to all the penetrations; either Required Action B.5.1 or Required Action B.5.2 must be performed for all the penetrations. Thus, this will not allow one penetration to be isolated by use of a manual valve and another penetration to be capable of being closed by an OPERABLE Containment Purge and Exhaust Isolation System. This is not the intent of the requirement. The requirement is based on ISTS LCO 3.9.4, which requires each penetration to be either: a) closed by a manual or automatic isolation valve, blind flange, or equivalent; or b) capable of being closed by an OPERABLE Containment Purge and Exhaust Isolation System. For consistency with the actual LCO requirement, ISTS 3.9.6 Required Actions B.5.1 and B.5.2 have been combined into a single Required Action in ITS 3.9.4 Required Action B.5. In addition, since ISTS 3.9.4 has not been adopted, the term OPERABLE has been deleted.
Furthermore, the title of the system has been changed to be consistent with the Kewaunee Power Station System name (i.e., Containment Ventilation Isolation System). Purge and Vent

Consistent with TSTF-265, a Note is added to ITS SR 3.9.4.2 that permits the performance of the SR to verify correct breaker alignment and power availability to be delayed until 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> after a required RHR pump is not in operation. This provision is required because when RHR pumps are swapped under the current requirements, the Surveillance is immediately not met on the RHR pump taken out of operation. This change avoids entering an Action for a routine operational occurrence. The change is acceptable because adequate assurance exists that the RHR pump is aligned to the correct breaker with power available because, prior to being removed from operation, the applicable pump had been in operation. Allowing 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> to perform the breaker alignment verification is acceptable because the RHR pump was in operation, which demonstrated OPERABILITY, and because 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> is allowed in the ISTS by Kewaunee Power Station Page 1 of 2 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 90 of 208

Furthermore, SRs in Section 3.4 (ITS SRs 3.4.6.1, 3.4.7.1, and 3.4.8.1) require a similar verification that the RHR loop is in operation, but do not specify a flow rate requirement. This change is also consistent with the KPS current Technical Specifications, which does not specify a flow rate for the RHR loop.

The purpose of the Containment Closure during Refueling requirements is to restrict the release of fission product radioactivity within containment from escaping to the environment following a fuel handling accident within the containment. The containment closure is not taken credit for in any accident analyses in the USAR. This is also documented in the NRC Safety Evaluation for License Amendment 190, dated March 8, 2007 (ADAMS Accession No. ML070430020). Therefore, the ITS does not include these Specifications. This changes the CTS by relocating the Containment Closure Specifications to the Technical Requirements Manual (TRM).
This change is acceptable because CTS 3.8.a.1 and 3.8.a.8 do not meet the 10 CFR 50.36(c)(2)(ii) criteria for inclusion into the ITS.
10 CFR 50.36(c)(2)(ii) Criteria Evaluation:
- 1. Containment closure is not installed instrumentation that is used to detect, and indicate in the control room, a significant abnormal degradation of the reactor coolant pressure boundary. The Containment Closure Specifications do not satisfy criterion 1.
- 2. Containment closure is not a process variable, design feature, or operating restriction that is in an initial condition of a DBA or Transient Analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. The Containment Closure Specifications do not satisfy criterion 2.
- 3. Containment closure is not a structure, system, or component that is part of the primary success path and which functions or actuates to mitigate a DBA or Transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. The Containment Closure Specifications do not satisfy criterion 3.
- 4. Containment closure was found to be non-significant risk contributor to core damage frequency and offsite releases. Dominion Energy Kewaunee (DEK) has performed a plant specific evaluation to ensure that the Containment Closure requirements do not contain constraints of prime importance in limiting the likelihood or severity of the accident Kewaunee Power Station Page 1 of 2 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 99 of 208

Since the 10 CFR 50.36(c)(2)(ii) criteria have not been met, the Containment Closure Specifications (CTS 3.8.a.1 and 3.8.a.8) may be relocated out of the Technical Specifications. The containment closure specification will be relocated to the TRM. Changes to the TRM will be controlled by the provisions of 10 CFR 50.59. This change is designated as relocation because the specifications did not meet the criteria in 10 CFR 50.36(c)(2)(ii) and has been relocated to the TRM.

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 123 of 208 DISCUSSION OF CHANGES ITS 3.9.6, CONTAINMENT PENETRATIONS ADMINISTRATIVE CHANGES A01 In the conversion of the Kewaunee Power Station (KPS) Current Technical Specifications (CTS) to the plant specific Improved Technical Specifications (ITS), certain changes (wording preferences, editorial changes, reformatting, revised numbering, etc.) are made to obtain consistency with NUREG-1431, Rev. 3.0, "Standard Technical Specifications-Westinghouse Plants" (ISTS).
These changes are designated as administrative changes and are acceptable because they do not result in technical changes to the CTS.
A02 When the containment penetrations are not in the required condition specified in CTS 3.8.a.1 or CTS 3.8.a.8, CTS 3.8.b requires refueling of the reactor to cease, initiation of action to restore the containment penetrations to the required conditions, and no operations be performed that could increase the reactivity of the core. Under similar conditions, ITS 3.9.6 ACTION A only requires movement of irradiated fuel assemblies within containment to be suspended. This changes the CTS by deleting the requirements to initiate action to restore the containment penetrations to the required conditions and that no operations be performed that could increase the reactivity of the core.
The purpose of CTS 3.8.a.8 is to ensure proper compensatory actions are taken to exit the Applicability of the LCO. CTS 3.8.a.1 and 3.8.a.8 are only applicable during REFUELING OPERATIONS, which is defined in CTS Section 1.0 as the movement of reactor vessel internals that could affect the reactivity of the core within the containment when the vessel head is unbolted or removed. Thus, after the first requirement of CTS 3.8.b is met (i.e., suspend refueling the reactor), the Applicability has been exited and thus, continuation of the requirements of CTS 3.8.b are not required. Therefore, this change is acceptable and is designated as administrative since the technical requirements have not been changed.
MORE RESTRICTIVE CHANGES M01 CTS 3.8.a does not provide a Surveillance Requirement to verify each required containment penetration is in the required status. The ITS adds a Surveillance Requirement (SR 3.9.6.1) to verify each required containment penetration is in the required status once every 7 days. This changes the CTS by adding a new Surveillance Requirement for the containment penetrations.
This change is acceptable because the added Surveillance Requirement ensures that each required containment penetration is in the required status to support the containment penetration conditions assumed in the Fuel Handling Accident (FHA) analysis. In addition, this change is acceptable because the Surveillance Requirement continues to ensure that the structures, systems, and components are maintained consistent with the safety analyses and licensing basis. This change is designated as more restrictive because a new Surveillance Requirement has been added.

CTS 3.8.a.1.a is modified by a footnote (1) that states "Administrative controls ensure that appropriate personnel are aware that both personnel air lock doors are open; a specified individual(s) is designated and available to close the air lock following a required evacuation of containment; and, any obstruction(s) (e.g.,
cables and hoses) that could prevent closure of an open air lock can be quickly removed." ITS 3.9.6 does not contain this footnote information or the 30 minute requirement. This changes the CTS by moving the information contained in the footnote and the 30 minute requirement to the Bases.
The removal of these details, which are related to procedural details for meeting Technical Specification requirements, from the Technical Specifications is acceptable because this type of information is not necessary to be included in the Technical Specifications to provide adequate protection of public health and safety. The ITS still retains the requirement for at least one door in each personnel air lock to be capable of being closed. Also, this change is acceptable because the removed information will be adequately controlled in the ITS Bases.
Changes to the Bases are controlled by the Technical Specification Bases Control Program in Chapter 5. This program provides for the evaluation of changes to ensure the Bases are properly controlled. This change is designated as a less restrictive removal of detail change because information relating to procedural details for meeting Technical Specification requirements is being removed from the Technical Specifications.
LESS RESTRICTIVE CHANGES L01 (Category 1 - Relaxation of LCO Requirements) CTS 3.8.a.1.a, in part, requires at least one door in each personnel air lock to be closed when the reactor vessel head or upper internals are being lifted. ITS 3.9.6 does not include this requirement. This changes the CTS by not requiring one door in each personnel air lock to be closed when the reactor vessel head or upper internals are being lifted.
The purpose of CTS 3.8.a.1 is to ensure that if a fuel handling accident occurs, the release of any subsequent fission products results in doses that are well within the guideline values specified in Regulatory Guide 1.183. A fuel handling accident, as analyzed in USAR Section 14.2.1, is postulated to occur during handling of irradiated fuel assemblies; not handling the vessel head or upper internals. Thus, moving the vessel head or upper internals cannot result in a fuel handling accident. Any additional requirements, above those required to meet the assumptions of the fuel handling accident, are more appropriately controlled Kewaunee Power Station Page 2 of 4 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 124 of 208
Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 125 of 208 DISCUSSION OF CHANGES ITS 3.9.6, CONTAINMENT PENETRATIONS by plant procedures. Therefore, this change is acceptable and is designated a less restrictive change since the requirement to maintain containment closure capability during movement of the vessel head or upper internals is being deleted from the CTS.
L02 (Category 1 - Relaxation of LCO Requirements) CTS 3.8.a.1.b, in part, states that each line that penetrates containment and which provides a direct air path from containment atmosphere to the outside atmosphere shall have a closed isolation valve. ITS LCO 3.9.6.c.1 states that each penetration providing direct access from the containment atmosphere to the outside atmosphere is closed by a manual or automatic isolation valve, blind flange, or equivalent. This changes the CTS by specifying the use of a blind flange or an equivalent means of isolating a containment penetration.
The purpose of CTS 3.8.a.1 is to ensure the containment penetrations are in the condition assumed in the Fuel Handling Accident (FHA) analysis. This change is acceptable because the LCO requirements continue to ensure that the structures, systems, and components are maintained consistent with the safety analyses and licensing basis. The addition of the option to use a blind flange or some other equivalent means of isolating the containment penetration allows additional flexibility in the ITS that was not available in CTS. This change is designated as less restrictive because less stringent LCO requirements are being applied in the ITS than were applied in the CTS.
L03 (Category 6 - Relaxation Of Surveillance Requirement Acceptance Criteria)
CTS 3.8.a.8 requires verification of the automatic actuation of the Containment Ventilation and Purge valves on a containment ventilation isolation signal. ITS SR 3.9.6.2 specifies that the signal may be from either an actual or simulated signal. This changes the CTS by explicitly allowing the use of either an actual or simulated signal to perform the Surveillance.
The purpose of CTS 3.8.a.8 is to ensure that the containment purge and vent valves operate correctly upon receipt of an actuation signal. This change is acceptable because it has been determined that the relaxed Surveillance Requirement acceptance criteria are not necessary for verification that the equipment used to meet the LCO can perform its required functions. Equipment cannot discriminate between an "actual," "simulated," or "test" signal and, therefore, the results of the testing are unaffected by the type of signal used to initiate the test. This change allows taking credit for unplanned actuation if sufficient information is collected to satisfy the Surveillance test requirements.
The change also allows a simulated signal to be used, if necessary. This change is designated as less restrictive because less stringent Surveillance Requirements are being applied in the ITS than were applied in the CTS.
L04 (Category 7 - Relaxation Of Surveillance Frequency) CTS 3.8.a.8 includes a Surveillance Frequency of "immediately prior to and daily during REFUELING OPERATIONS" for performing a Surveillance of the Containment Ventilation and Purge System. The ITS SR 3.9.6.2 Frequency for the same requirement is 18 months. ITS SR 3.9.6.2 is also modified by a Note that states that SR 3.9.6.2 is not required to be met for containment purge and vent valve(s) in penetrations that are closed to comply with LCO 3.9.6.c.1. This changes the CTS by Kewaunee Power Station Page 3 of 4 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 125 of 208
Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 126 of 208 DISCUSSION OF CHANGES ITS 3.9.6, CONTAINMENT PENETRATIONS changing the Surveillance Frequency from immediately prior to and daily during REFUELING OPERATIONS to 18 months and adding the Note that the SR is not required to be met for containment purge and vent valve(s) in penetrations that are closed to comply with ITS LCO 3.9.6.c.1.
The purpose of CTS 3.8.a.8 is to verify the equipment required to meet the LCO is OPERABLE. This change is acceptable because the new Surveillance Frequency has been evaluated to ensure that it provides an acceptable level of equipment reliability. Containment purge and vent valve testing is still required, but at a Frequency consistent with the testing Frequency for containment isolation valves required in MODES 1, 2, 3, and 4. This Frequency provides an appropriate degree of assurance that the valves are OPERABLE. When containment purge and vent valve(s) in penetrations are closed to comply with ITS LCO 3.9.6.c.1, the penetrations are in the expected condition (isolated) to mitigate the effects of a fuel handling accident inside containment. Therefore, there is no need for the actuation signal to reposition the valves to the closed position. This change is designated as less restrictive because Surveillances will be performed less frequently under the ITS than under the CTS.
L05 (Category 1 - Relaxation of LCO Requirements) CTS 3.8.a specifies that the CTS 3.8.a.1 containment closure requirements are applicable during REFUELING OPERATIONS, which is defined in CTS Section 1.0 as the movement of reactor vessel internals that could affect the reactivity of the core within the containment when the vessel head is unbolted or removed. ITS 3.9.6 is applicable during movement of irradiated fuel assemblies within containment.
This changes the CTS by not requiring the containment closure requirements to be met when moving or handling control rods during MODE 6 operation.
The purpose of CTS 3.8.a.1 is to ensure that if a fuel handling accident occurs, the release of any subsequent fission products results in doses that are well within the guideline values specified in Regulatory Guide 1.183. A fuel handling accident, as analyzed in USAR Section 14.2.1, can only occur during handling of irradiated fuel assemblies; not moving or handling control rods (which are the only other reactor vessel internals currently in use at KPS that could affect reactivity of the core). Thus, moving or handling the control rods cannot result in a fuel handling accident. Any additional requirements, above those required to meet the assumptions of the fuel handling accident, are more appropriately controlled by plant procedures. Therefore, this change is acceptable and is designated a less restrictive change since the requirement to maintain containment closure capability during movement or handling of control rods in MODE 6 is being deleted from the CTS.

BASES BACKGROUND During movement of [recently] irradiated fuel assemblies within containment, a release of fission product radioactivity within containment will be restricted from escaping to the environment when the LCO requirements are met. In MODES 1, 2, 3, and 4, this is accomplished by maintaining containment OPERABLE as described in LCO 3.6.1, "Containment." In MODE 6, the potential for containment pressurization as a result of an accident is not likely; therefore, requirements to isolate the containment from the outside atmosphere can be less stringent. The LCO requirements are referred to as "containment closure" rather than "containment OPERABILITY." Containment closure means that all potential escape paths are closed or capable of being closed. Since there is no potential for containment pressurization, the Appendix J leakage criteria and tests are not required.
The containment serves to contain fission product radioactivity that may be released from the reactor core following an accident, such that offsite radiation exposures are maintained well within the requirements of guidance 2 Regulatory Guide 1.183 (Ref. 1) 10 CFR 100. Additionally, the containment provides radiation shielding from the fission products that may be present in the containment atmosphere following accident conditions.
The containment equipment hatch, which is part of the containment pressure boundary, provides a means for moving large equipment and components into and out of containment. During movement of [recently]
irradiated fuel assemblies within containment, the equipment hatch must be held in place by at least four bolts. Good engineering practice dictates that the bolts required by this LCO be approximately equally spaced.
The containment air locks, which are also part of the containment pressure boundary, provide a means for personnel access during MODES 1, 2, 3, and 4 unit operation in accordance with LCO 3.6.2, "Containment Air Locks." Each air lock has a door at both ends. The doors are normally interlocked to prevent simultaneous opening when containment OPERABILITY is required. During periods of unit shutdown when containment closure is not required, the door interlock mechanism may be disabled, allowing both doors of an air lock to remain open for extended periods when frequent containment entry is necessary.
During movement of [recently] irradiated fuel assemblies within containment, containment closure is required; therefore, the door interlock mechanism may remain disabled, but one air lock door must always remain [capable of being] closed.

BASES TSTF-471-A APPLICABLE During CORE ALTERATIONS or movement of irradiated fuel assemblies SAFETY within containment, the most severe radiological consequences result ANALYSES from a fuel handling accident [involving handling recently irradiated fuel].
The fuel handling accident is a postulated event that involves damage to 2 irradiated fuel (Ref. 2). Fuel handling accidents, analyzed in Reference 3, 2 vertically onto a rigid surface or include dropping a single irradiated fuel assembly and handling tool or a heavy object onto other irradiated fuel assemblies. The requirements of 5 LCO 3.9.7, "Refueling Cavity Water Level," in conjunction with a minimum 7 decay time of 100 hours0.00116 days <br />0.0278 hours <br />1.653439e-4 weeks <br />3.805e-5 months <br /> prior to [irradiated fuel movement with containment closure capability or a minimum decay time of [x] days Regulatory Guide 1.183 without containment closure capability], ensures that the release of fission (Ref. 1) product radioactivity, subsequent to a fuel handling accident, results in 2
doses that are well within the guideline values specified in 10 CFR 100.
Standard Review Plan, Section 15.7.4, Rev. 1 (Ref. 3), defines "well within" 10 CFR 100 to be 25% or less of the 10 CFR 100 values. The 2
acceptance limits for offsite radiation exposure will be 25% of 10 CFR 100 values or the NRC staff approved licensing basis (e.g., a specified fraction of 10 CFR 100 limits).
Containment penetrations satisfy Criterion 3 of 10 CFR 50.36(c)(2)(ii).
LCO -----------------------------------REVIEWERS NOTE-----------------------------------
The allowance to have containment personnel air lock doors open and TSTF-471-A penetration flow paths with direct access from the containment atmosphere to the outside atmosphere to be unisolated during fuel movement and CORE ALTERATIONS is based on (1) confirmatory dose calculations of a fuel handling accident as approved by the NRC staff which indicate acceptable radiological consequences and 3 (2) commitments from the licensee to implement acceptable administrative procedures that ensure in the event of a refueling accident (even though the containment fission product control function is not required to meet acceptable dose consequences) that the open air lock can and will be promptly closed following containment evacuation and that the open penetration(s) can and will be promptly closed. The time to close such penetrations or combination of penetrations shall be included in the confirmatory dose calculations.
This LCO limits the consequences of a fuel handling accident [involving 2 handling recently irradiated fuel] in containment by limiting the potential escape paths for fission product radioactivity released within containment.
The LCO requires any penetration providing direct access from the containment atmosphere to the outside atmosphere to be closed except for the OPERABLE containment purge and exhaust penetrations [and the 2 vent containment personnel air locks]. For the OPERABLE WOG STS B 3.9.4-3 Rev. 3.0, 03/31/04 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 135 of 208

The OPERABILITY requirements for this LCO ensure 2 that the automatic purge and exhaust valve closure times specified in the FSAR can be achieved and, therefore, meet the assumptions used in the safety analysis to ensure that releases through the valves are terminated, such that radiological doses are within the acceptance limit.
The LCO is modified by a Note allowing penetration flow paths with direct 8 access from the containment atmosphere to the outside atmosphere to be unisolated under administrative controls. Administrative controls ensure that 1) appropriate personnel are aware of the open status of the TSTF-471-A penetration flow path during CORE ALTERATIONS or movement of irradiated fuel assemblies within containment, and 2) specified individuals are designated and readily available to isolate the flow path in the event of a fuel handling accident.

within 30 minutes The containment personnel air lock doors many be open during movement of [recently] irradiated fuel in the containment provided that 1 one door is capable of being closed in the event of a fuel handling 2 INSERT 2 accident. Should a fuel handling accident occur inside containment, one 2 personnel air lock door will be closed following an evacuation of containment.
APPLICABILITY The containment penetration requirements are applicable during 1
movement of [recently] irradiated fuel assemblies within containment because this is when there is a potential for the limiting fuel handling accident. In MODES 1, 2, 3, and 4, containment penetration requirements are addressed by LCO 3.6.1. In MODES 5 and 6, when movement of irradiated fuel assemblies within containment is not being conducted, the potential for a fuel handling accident does not exist.
[Additionally, due to radioactive decay, a fuel handling accident involving handling recently irradiated fuel (i.e., fuel that has occupied part of a 1 critical reactor core within the previous [x] days) will result in doses that are well within the guideline values specified in 10 CFR 100 even without containment closure capability.] Therefore, under these conditions no requirements are placed on containment penetration status.

REVIEWERS NOTE-----------------------------------
The addition of the term "recently" associated with handling irradiated fuel in all of the containment function Technical Specification requirements is only applicable to those licensees who have demonstrated by analysis that after sufficient radioactive decay has occurred, off-site doses resulting from a fuel handling accident remain below the Standard Review Plan limits (well within 10 CFR 100).
Additionally, licensees adding the term "recently" must make the following commitment which is consistent with NUMARC 93-01, Revision 4, Section 11.3.6.5 "Safety Assessment for Removal of Equipment from Service During Shutdown Conditions," subheading "Containment -
Primary (PWR)/Secondary (BWR)."
"The following guidelines are included in the assessment of systems removed from service during movement irradiated fuel:
3
- During fuel handling/core alterations, ventilation system and radiation monitor availability (as defined in NUMARC 91-06) should be assessed, with respect to filtration and monitoring of releases from the fuel. Following shutdown, radioactivity in the fuel decays away fairly rapidly. The basis of the Technical Specification OPERABILITY amendment is the reduction in doses due to such decay. The goal of maintaining ventilation system and radiation monitor availability is to reduce doses even further below that provided by the natural decay.
- A single normal or contingency method to promptly close primary or secondary containment penetrations should be developed. Such prompt methods need not completely block the penetration or be capable of resisting pressure.
The purpose of the "prompt methods" mentioned above are to enable ventilation systems to draw the release from a postulated fuel handling accident in the proper direction such that it can be treated and monitored."

This is accomplished by immediately suspending movement of
[recently] irradiated fuel assemblies within containment. Performance of 1 these actions shall not preclude completion of movement of a component to a safe position.

SURVEILLANCE SR 3.9.4.1 required is in the REQUIREMENTS This Surveillance demonstrates that each of the containment penetrations required to be in its closed position is in that position. The Surveillance status 2
vent on the open purge and exhaust valves will demonstrate that the valves are not blocked from closing. Also the Surveillance will demonstrate that each valve operator has motive power, which will ensure that each valve is capable of being closed by an OPERABLE automatic containment purge and exhaust isolation signal.
The Surveillance is performed every 7 days during movement of [recently] 1 irradiated fuel assemblies within containment. The Surveillance interval is selected to be commensurate with the normal duration of time to complete fuel handling operations. A surveillance before the start of refueling operations will provide two or three surveillance verifications during the applicable period for this LCO. As such, this Surveillance ensures that a postulated fuel handling accident [involving handling 1 recently irradiated fuel] that releases fission product radioactivity within the containment will not result in a release of significant fission product radioactivity to the environment in excess of those recommended by Regulatory Guide 1.183 Standard Review Plan Section 15.7.4 (Reference 3). 2 1

SR 3.9.4.2 required vent This Surveillance demonstrates that each containment purge and exhaust valve actuates to its isolation position on manual initiation or on an actual or simulated high radiation signal. The 18 month Frequency maintains 2 consistency with other similar ESFAS instrumentation and valve testing requirements.

Every 18 months a CHANNEL CALIBRATION is 2 performed. The system actuation response time is demonstrated every 18 months, during refueling, on a STAGGERED TEST BASIS.
SR 3.6.3.5 demonstrates that the isolation time of each valve is in accordance with the Inservice Testing Program requirements. These Surveillances performed during MODE 6 will ensure that the valves are capable of closing after a postulated fuel handling accident [involving 1 handling recently irradiated fuel] to limit a release of fission product 2 radioactivity from the containment.
The SR is modified by a Note stating that this Surveillance is not required to be met for valves in isolated penetrations. The LCO provides the option to close penetrations in lieu of requiring automatic actuation capability.

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 147 of 208 Appendix A - Justification For Specification Relocation 3.8.a.1: Containment Closure Page Blank 3.8.a.8: Containment Closure DISCUSSION:
CTS 3.8.a.1 and 3.8.a.8 provide requirements for Containment Closure during refueling operations.
The purpose of the Containment Closure during Refueling requirements is to restrict the release of fission product radioactivity within containment from escaping to the environment following a fuel handling accident within the containment.
COMPARISON TO SCREENING CRITERIA:
- 1. Containment closure is not installed instrumentation that is used to detect, and indicate in the control room, a significant abnormal degradation of the reactor coolant pressure boundary.
- 2. Containment closure is not a process variable, design feature, or operating restriction that is in an initial condition of a DBA or Transient Analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier.
- 3. Containment closure is not a structure, system, or component that is part of the primary success path and which functions or actuates to mitigate a DBA or Transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier.
- 4. Containment closure was found to be non-significant risk contributor to core damage frequency and offsite releases.
CONCLUSION:
Since the screening criteria have not been satisfied, the Containment Closure Specifications may be relocated to other plant controlled documents outside Technical Specifications.

NOTE: KAB-031 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 157 of 208 changes shown in green DISCUSSION OF CHANGES ITS 3.3.6, CONTAINMENT PURGE AND VENT ISOLATION INSTRUMENTATION The removal of these details, which are related to system design, from the Technical Specifications is acceptable because this type of information is not necessary to be included to provide adequate protection of public health and safety. The ITS still retains the requirement for the Containment Purge and Vent Isolation Instrumentation be OPERABLE and specifies the number of required channels. Also, this change is acceptable because the removed information will be adequately controlled in the ITS Bases. Changes to the Bases are controlled by the Technical Specification Bases Control Program in ITS Chapter 5. This program provides for the evaluation of changes to ensure the Bases are properly controlled. This change is designated as a less restrictive removal of detail change because information relating system design is being removed from the Technical Specifications.
LESS RESTRICTIVE CHANGES L01 (Category 4 - Relaxation of Required Action) When both Containment Isolation Manual channels are inoperable, CTS Table TS 3.5-4 Column 6 requires the unit to be placed in HOT SHUTDOWN (ITS MODE 3). Under similar conditions, Not ITS 3.3.6 Required Action B.1 requires immediately entering the applicable used.
Conditions and Required Actions for the containment purge and vent isolation valves made inoperable by isolation instrumentation. This changes the CTS by allowing the actions for inoperable containment purge and vent valves to be taken when both Manual initiation channels are inoperable in lieu of shutting down the unit.
The purpose of the CTS Table TS 3.5-4 Column 6 action is to provide compensatory actions when both Manual Initiation channels are inoperable.
However, the CTS action is overly conservative in that it requires more restrictive actions than are allowed if the valves themselves were inoperable. The purpose of the instrumentation is to isolate the associated valves. Thus, this change is acceptable since the proposed ITS Required Action would accomplish this action (since ITS 3.6.3 would require isolation of the associated penetration flow path).
This change is designated as less restrictive since the proposed Required Action will allow operation to continue with the associated flow path isolated in lieu of shutting down the unit.

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 158 of 208 L02 (Category 2 - Relaxation of Applicability) CTS 3.8.a.1.b requires an OPERABLE automatic isolation valve under certain conditions. This is referring to the Containment Purge and Vent System valves, and thus includes the instruments that provide the isolation signal. The Specification is applicable during REFUELING OPERATIONS. This requirement can be met by an OPERABLE automatic isolation valve or a closed isolation valve. When this requirement is not being met, CTS 3.8.b provides actions to be taken if any of the specified limiting conditions in CTS 3.8 a are not met during REFUELING OPERATIONS. ITS 3.3.6 is applicable, in part, during movement of irradiated fuel assemblies within containment, as stated in footnote (a) to Table 3.3.6-1. This changes the CTS by requiring the containment purge and vent isolation instrumentation be OPERABLE during times of movement of irradiated fuel assemblies within containment, in lieu of during REFUELING OPERATIONS.
The purpose of CTS 3.8.a.1.b is to ensure each line that penetrates containment and provides a direct air path from containment atmosphere to the outside atmosphere have a closed isolation valve or an OPERABLE automatic isolation valve. Continuous monitoring of the radiation levels of the containment atmosphere (general or exhaust vent) is required to provide automatic action during an unsafe condition as a result of a fuel handling accident. CTS 3.8.a.1.b requires an OPERABLE automatic isolation valve during REFUELING OPERATIONS, and includes the isolation instrumentation. As defined in CTS Section 1.0, REFUELING OPERATIONS is movement of reactor vessel internal components that could affect the reactivity of the core within the containment when the vessel head is unbolted or removed. This would include both moving irradiated fuel assemblies and control rods. Since movement of irradiated fuel assemblies within containment can only occur when the vessel head is unbolted or removed, ITS 3.3.6 is applicable, with respect to moving fuel assemblies, under the same conditions as CTS 3.8.a.1.b. This change is acceptable because the requirements continue to ensure that the process variables are maintained in the MODES and other specified conditions assumed in the safety analyses and licensing basis. The fuel handling accident is based on damaging a single irradiated fuel assembly. Movement of control rods is not assumed to result in a fuel handling accident. This change is designated as less restrictive because the LCO requirements are applicable in fewer operating conditions than in the CTS.
L03 (Category 4 - Relaxation of Required Action) CTS 3.8.a.1.b requires an OPERABLE automatic isolation valve under certain conditions. This is referring to the Containment Purge and Vent System valves, and thus includes the instruments that provide the isolation signal. The Specification is applicable during REFUELING OPERATIONS.
When this requirement is not being met, the isolation valve must be closed or CTS 3.8.b requires refueling of the reactor to cease, initiation of action to restore the monitoring capability, and no operations be performed that could increase the reactivity of the core.
Under similar conditions, ITS 3.3.6 does not require the refueling of the reactor to cease or require all operations that could increase the reactivity of the core to cease. With one radiation monitoring channel inoperable, ITS 3.3.6 ACTION A requires restoration of the affected channel to OPERABLE status within 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br />.

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 159 of 208 only applicable during the movement of irradiated fuel assemblies within containment, requires immediately placing and maintaining containment purge and vent valves in the closed position (Required Action C.1) or immediately entering the applicable Conditions and Required Actions of LCO 3.9.6 for containment purge and vent valves made inoperable by isolation instrumentation (Required Action C.2). Note that under this condition ITS LCO 3.9.6 would require suspension of movement of irradiated fuel assemblies in containment. This changes the CTS by deleting the requirements to cease refueling of the reactor and that no operations be performed that could increase the reactivity of the core and provides new ACTIONS to restore the radiation monitors to service and maintain the containment boundary.
The purpose of CTS 3.8.a.1.b is to ensure the Containment Purge and Vent System is OPERABLE to provide automatic actuation of the valves if an unsafe condition as a result of a fuel handling accident occurs or the valves are closed. CTS 3.8.b requires compensatory actions be taken to exit the Applicability of the LCO if continuous monitoring is not available and the isolation valves cannot be closed; however, the CTS Actions are overly restrictive. The proposed compensatory actions of ITS 3.3.6 ACTIONS A and C ensure that acceptable actions are taken when radiation channels are inoperable. The proposed ACTION A is acceptable since channels are still available to ensure the containment purge and vent valve receive an isolation signal. The proposed ACTION C is acceptable since when multiple channels are inoperable, the proposed action places the containment purge and vent valves in the isolated position, which performs the function of the radiation channels. This change is designated as less restrictive since less restrictive actions have been added for when the radiation channels are inoperable.

ISTS 3.3.6 ACTION C provides the actions when two or more radiation monitoring channels are inoperable or when the Required Action and associated Completion Time of Condition A is not met during movement of recently irradiated fuel assemblies within containment. ISTS 3.3.6 ACTION C requires immediately placing and maintaining containment purge and exhaust valves in the closed position or to immediately enter the applicable Conditions and Required Actions of LCO 3.9.4, "Containment Penetrations," for containment purge and exhaust isolation valves made inoperable by isolation instrumentation. Kewaunee Power Station (KPS) does not credit containment isolation in a fuel handling accident analysis in the USAR. Therefore, ITS 3.3.6 does not maintain the applicability of during movement of recently irradiated fuel assemblies within containment as part of the Applicability. Therefore, all requirements related to movement of irradiated fuel assemblies in the containment (Table 3.3.6-1 Footnote (a) and ACTION C) have been deleted. In addition, due to this deletion, the Note to Condition B has been deleted since it is not necessary (there are no Actions other than those for MODES 1, 2, 3, and 4).
- 4. The ISTS contains a Surveillance Requirement (SR) for an ACTUATION LOGIC TEST (ISTSSR 3.3.6.2) for the Containment Purge and Vent Isolation Instrumentation that is performed every 31 days on a STAGGERED TEST BASIS.
The ISTS also contains an ACTUATION LOGIC TEST (ISTS SR 3.3.6.4) for the Containment Purge and Vent Isolation Instrumentation that is performed every 92 days on a STAGGERED TEST BASIS. ISTS SR 3.3.6.4 was added to the ISTS as part of the incorporation of TSTF-411, which, in part, increases the surveillance test interval (STI) for the actuation logic and actuation relays. The basis for the increase in the STI is WCAP-15376-P, Revision 0, which is consistent with the Nuclear Regulatory Commission's (NRC) approach for using probabilistic risk assessment in risk-informed decisions on plant-specific changes to the current licensing basis as presented in Regulatory Guides 1.174, "An Approach for Using Probabilistic Risk Assessment in Risk-Informed Decisions on Plant-Specific Changes to the Current Licensing Basis," and 1.177, "An Approach for Plant-Specific, Risk-Informed Decisionmaking: Technical Specifications." KPS has elected to adopt the specific ISTS changes authorized by the results of WCAP-15376-P Revision 0. Therefore, the bracketed ISTS SR 3.3.6.4 (ITS SR 3.3.6.2) has been adopted for testing of the actuation logic and actuation relays.
Subsequent Surveillance Requirements have been renumbered as a result of not including ISTS SR 3.3.6.2 in the ITS.

10 CFR 50, Appendix J. Therefore, leakage rates exceeding these individual limits only result in the containment being inoperable when the leakage results in exceeding the overall acceptance criteria of 1.0 La.
APPLICABILITY In MODES 1, 2, 3, and 4, a DBA could cause a release of radioactive material into containment. In MODES 5 and 6, the probability and consequences of these events are reduced due to the pressure and temperature limitations of these MODES. Therefore, containment is not required to be OPERABLE in MODE 5 to prevent leakage of radioactive material from containment. The requirements for containment during MODE 6 are addressed in LCO 3.9.4, "Containment Penetrations." 11 3

B.1 and B.2 If containment cannot be restored to OPERABLE status within the required Completion Time, the plant must be brought to a MODE in which the LCO does not apply.

This allowable leakage rate forms the basis for the acceptance criteria imposed on the SRs associated with the air locks.
The containment air locks satisfy Criterion 3 of 10 CFR 50.36(c)(2)(ii).
LCO Each containment air lock forms part of the containment pressure boundary. As part of the containment pressure boundary, the air lock safety function is related to control of the containment leakage rate resulting from a DBA. Thus, each air lock's structural integrity and leak tightness are essential to the successful mitigation of such an event.
Each air lock is required to be OPERABLE. For the air lock to be considered OPERABLE, the air lock interlock mechanism must be OPERABLE, the air lock must be in compliance with the Type B air lock leakage test, and both air lock doors must be OPERABLE. The interlock allows only one air lock door of an air lock to be opened at one time. This provision ensures that a gross breach of containment does not exist when containment is required to be OPERABLE. Closure of a single door in each air lock is sufficient to provide a leak tight barrier following postulated events. Nevertheless, both doors are kept closed when the air lock is not being used for normal entry into or exit from containment.
APPLICABILITY In MODES 1, 2, 3, and 4, a DBA could cause a release of radioactive material to containment. In MODES 5 and 6, the probability and consequences of these events are reduced due to the pressure and temperature limitations of these MODES. Therefore, the containment air locks are not required in MODE 5 to prevent leakage of radioactive material from containment. The requirements for the containment air locks during MODE 6 are addressed in LCO 3.9.3, "Containment 10 Penetrations." 6 ACTIONS The ACTIONS are modified by a Note that allows entry and exit to If the inner 5 perform repairs on the affected air lock component. If the outer door is door is inoperable, inoperable, then it may be easily accessed for most repairs. It is then preferred that the air lock be accessed from inside primary containment by entering through the other OPERABLE air lock. However, if this is not practicable, or if repairs on either door must be performed from the barrel side of the door then it is permissible to enter the air lock through the OPERABLE door, which means there is a short time during which the containment boundary is not intact (during access through the WOG STS B 3.6.2-2 Rev. 3.0, 03/31/04 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 169 of 208

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 174 of 208 DISCUSSION OF CHANGES ITS 3.9.3, RHR AND COOLANT CIRCULATION - HIGH WATER LEVEL verification that each penetration providing direct access from the containment atmosphere to the outside atmosphere is either closed with a manual or an OPERABLE automatic isolation valve, blind flange, or equivalent, or is capable of being closed by a Containment Ventilation and Purge Isolation System in 4 hours4.62963e-5 days <br />0.00111 hours <br />6.613757e-6 weeks <br />1.522e-6 months <br /> (Required Action A.6). This changes the CTS by adding new Required Actions when the required RHR loop is inoperable. and Vent These added Required Actions are acceptable since they assist in minimizing the consequences of the required RHR loop being inoperable. Note that while CTS 3.8.b requires operations not be performed that could increase the reactivity of the core, this action is actually not required to be taken since once movement of fuel has been suspended, REFUELING OPERATIONS has ceased (thus, the LCO requirements of CTS 3.8.a are not required to be met). Thus, the addition of a similar Required Action (Required Action A.1), as well as the other above described Required Actions, is designated as more restrictive.
M03 CTS 3.1.a.1.A does not contain any ACTIONS to take should there be less than the required number of RHR pumps in operation. As a result, CTS 3.0.c would normally be entered. However, LCO 3.0.c states that it is not applicable in COLD SHUTDOWN or REFUELING. Since the RHR pump only has to be in operation when a reduction in boron concentration is being made, and for this Specification, the unit is already in MODE 6, the CTS does not provide any compensatory measures. Therefore, 10 CFR 50.36 (c)(2)(i) would apply, which states to shutdown the unit. However, no times are provided to complete the shutdown and no further actions (i.e., suspend boron concentration reductions) are required. Note that while no ACTIONS are required, KPS in all likelihood would suspend dilution if this occurred. ITS 3.9.3 ACTION A specifies the Required Actions for a required RHR loop not in operation, and requires immediate suspension of operations that would cause introduction of coolant into the RCS with a boron concentration less than required to meet the boron concentration of LCO 3.9.1 (Required Action A.1), immediate suspension of loading irradiated fuel assemblies into the core (Required Action A.2), immediate initiation of action to restore one RHR loop to operation (Required Action A.3),

Purge and Vent The purpose of the Actions should be to place the unit outside of the Applicability of the Specification. ITS 3.9.3 ACTION A effectively places the unit in an equivalent condition by requiring the plant to immediately suspend operations that would cause introduction of coolant into the RCS with a boron concentration less than required to meet the boron concentration of LCO 3.9.1 and to initiate action to restore one RHR loop to operation. The proposed Required Actions reflect the importance of maintaining operation for decay heat removal and boron mixing. This change is designated as more restrictive because a new proposed ACTION has been added.

Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 190 of 208 DISCUSSION OF CHANGES CTS 3.8.a.1 and 3.8.a.8, CONTAINMENT PENETRATIONS ADMINISTRATIVE CHANGES None MORE RESTRICTIVE CHANGES None RELOCATED SPECIFICATIONS R01 CTS 3.8.a.1 and 3.8.a.8 provide requirements for Containment Closure during refueling operations. The purpose of the Containment Closure during Refueling requirements is to restrict the release of fission product radioactivity within containment from escaping to the environment following a fuel handling accident within the containment. The containment closure is not taken credit for in any accident analyses in the USAR. This is also documented in the NRC Safety Evaluation for License Amendment 190, dated March 8, 2007 (ADAMS Accession No. ML070430020). Therefore, the ITS does not include these Specifications. This changes the CTS by relocating the Containment Closure Specifications to the Technical Requirements Manual (TRM).
This change is acceptable because CTS 3.8.a.1 and 3.8.a.8 do not meet the 10 CFR 50.36(c)(2)(ii) criteria for inclusion into the ITS.
10 CFR 50.36(c)(2)(ii) Criteria Evaluation:
- 1. Containment closure is not installed instrumentation that is used to detect, and indicate in the control room, a significant abnormal degradation of the reactor coolant pressure boundary. The Containment Closure Specifications do not satisfy criterion 1.
- 2. Containment closure is not a process variable, design feature, or operating restriction that is in an initial condition of a DBA or Transient Analysis that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. The Containment Closure Specifications do not satisfy criterion 2.
- 3. Containment closure is not a structure, system, or component that is part of the primary success path and which functions or actuates to mitigate a DBA or Transient that either assumes the failure of or presents a challenge to the integrity of a fission product barrier. The Containment Closure Specifications do not satisfy criterion 3.
- 4. Containment closure was found to be non-significant risk contributor to core damage frequency and offsite releases. Dominion Energy Kewaunee (DEK) has performed a plant specific evaluation to ensure that the Containment Closure requirements do not contain constraints of prime importance in limiting the likelihood or severity of the accident Kewaunee Power Station Page 1 of 2 Enclosure, Q&A to Attachment 1, Volume 14 (Section 3.9) Page 190 of 208

Since the 10 CFR 50.36(c)(2)(ii) criteria have not been met, the Containment Closure Specifications (CTS 3.8.a.1 and 3.8.a.8) may be relocated out of the Technical Specifications. The containment closure specification will be relocated to the TRM. Changes to the TRM will be controlled by the provisions of 10 CFR 50.59. This change is designated as relocation because the specifications did not meet the criteria in 10 CFR 50.36(c)(2)(ii) and has been relocated to the TRM.
