Attachment 1 to W3F1-2016-0036 Description and Assessment of Technical Specification Changes to W3F1-2016-0036 Page 1 of 6 Description and Assessment of Technical Specification Changes
1.0 DESCRIPTION
The proposed change eliminates the Technical Specifications (TS), Section 6.5.8, Inservice Testing (IST) Program, to remove requirements duplicated in American Society of Mechanical Engineers (ASME) Code for Operations and Maintenance of Nuclear Power Plants (OM Code),
Case OMN-20, Inservice Test Frequency." A new defined term, "Inservice Testing Program," is added to TS Section 1.0, "Definitions. The proposed change to the TS is consistent with TSTF-545, Revision 3, TS Inservice Testing Program Removal & Clarify SR Usage Rule Application to Section 5.5 Testing.
2.0 ASSESSMENT 2.1 Applicability of Published Safety Evaluation Entergy Operations, Inc. (Entergy), has reviewed the model safety evaluation (SE) addressed to the Technical Specifications Task Force in a letter dated December 11, 2015, (ADAMS Accession No. ML15317A071). This review included a review of the NRC staffs evaluation, as well as the information provided in TSTF-545. Entergy concluded that the justifications presented in TSTF-545, and the model safety evaluation prepared by the NRC staff are applicable to Waterford Steam Electric Station, Unit 3 (Waterford 3) and justify this amendment for the incorporation of the changes to the Waterford 3 TS.
Waterford 3 was issued a construction permit on November 14, 1972 (CPPR-103), and the provisions of 10 CFR 50.55a(f)(2) are applicable.
2.2 Variations The Waterford 3 TSs (NUREG-0973) are of an older standard version and have not been converted to the improved standard TSs (ISTSs) based on NUREG 1432, Standard Technical Specifications - Combustion Engineering Plants, Revision 4. Entergy performed a search of the entire Waterford 3 TSs for the key phrase inservice testing program and IST. TS numbering generally differs from that of the ISTS. Actual TS wording may also differ.
Therefore, each Waterford 3 TS is listed in the following table, along with the ISTS listing from TSTF-545, with any differences or variations discussed individually. While Entergy has confirmed that TSTF-545 and its associated model SE are applicable to Waterford 3, because of the non-ISTS Waterford 3 version, it is understood that this amendment request will not be reviewed under the Consolidated Line Item Improvement Process (CLIIP). Minor page formatting/cleanup is performed where appropriate which is not discussed further in this submittal.
to W3F1-2016-0036 Page 2 of 6 Waterford 3 TS ISTS Differences Unlike the ISTS, the Waterford 3 TS Definitions are numbered and are not in alphabetical order. Therefore, the New 1.40 Section 1.1 INSERVICE TESTING PROGRAM definition is added as new Definition 1.40 to TS Page 1-8, keeping the current Waterford 3 TS formatting.
There are minor wording differences between the SR 4.4.2.1 SR 3.4.10.1 respective Waterford 3 SR and the ISTS version of TSTF-545; however, the IST program capitalization remains applicable.
The respective Waterford 3 SR lists specific requirements SR 4.4.5.2.3 SR 3.4.14.1 and does not refer to the IST program. Therefore, this TS page is not included in this amendment request.
There are wording differences between the respective SR 4.5.2.f SR 3.5.2.4 Waterford 3 SR and ISTS version of TSTF-545; however, the IST program capitalization remains applicable.
The Waterford 3 Charging Pump TS is applicable in Modes 5 and 6 and the Waterford 3 SR states that no additional SR 4.1.2.3 SR 3.5.2.5 SRs are required other than those required by the IST program. The IST program capitalization remains applicable.
The IST program is listed in the Waterford 3 SR is associated with testing of the Boric Acid Pumps. Because SR 4.1.2.5 NA the IST program capitalization remains applicable this TS page is included in the appropriate attachments of this amendment request.
SR 4.4.2.2 SR 3.4.10.1 There are minor wording differences between the respective Waterford 3 SR and the ISTS version of TSTF-545; however, the IST program capitalization remains applicable.
SR 4.4.8.3.1 NA The IST program is listed in the Waterford 3 SR is associated with testing of the Shutdown Cooling Relief Valves. Because the IST program capitalization remains applicable this TS page is included in the appropriate attachments of this amendment request.
There are minor wording differences between the SR 4.6.3.3 SR 3.6.3.5 respective Waterford 3 SR and the ISTS version of TSTF-545; however, the IST program capitalization remains applicable.
There are wording differences between the respective SR 4.6.2.1.c SR 3.6.6A.5 Waterford 3 SR and ISTS version of TSTF-545; however, the IST program capitalization remains applicable.
There are wording differences between the respective SR 4.6.2.1.c SR 3.6.6B.5 Waterford 3 SR and ISTS version of TSTF-545; however, the IST program capitalization remains applicable.
NA SR 3.6.7.4 No corresponding Waterford 3 Technical Specification exists.
There are wording differences between the respective SR 4.6.5 SR 3.6.12.1 Waterford 3 SR and ISTS version of TSTF-545; however, to W3F1-2016-0036 Page 3 of 6 Waterford 3 TS ISTS Differences the IST program capitalization remains applicable.
There are minor wording differences between the SR 4.7.1.1 SR 3.7.1.1 respective Waterford 3 SR and the ISTS version of TSTF-545; however, the IST program capitalization remains applicable.
There are minor wording differences between the SR 4.7.1.5.a SR 3.7.2.1 respective Waterford 3 SR and the ISTS version of TSTF-545; however, the IST program capitalization remains applicable.
There are minor wording differences between the respective Waterford 3 SR and the ISTS version of TSTF-SR 4.7.1.6.a SR 3.7.3.1 545; however, the IST program capitalization remains applicable.
There are wording differences between the respective SR 4.7.1.2.b SR 3.7.5.2 Waterford 3 SR and ISTS version of TSTF-545; however, the IST program capitalization remains applicable.
The IST program listed in the Waterford 3 SR is associated with testing of the Atmospheric Dump Valves. Because the SR 4.7.1.7.c NA IST program capitalization remains applicable this TS page is included in the appropriate attachments of this amendment request.
6.5.8 5.5.8 Inservice Testing Program is deleted from the technical specifications as discussed in TSTF-545.
TSTF-545 deletes the IST program TS 6.5.8 (ISTS 5.5.8) as discussed in TSTF-545. This also impacts several TS Bases references. Entergy proposes to retain the TS 6.5.8 reference, now shown as DELETED, and not change the subsequent TS program numbers. These program numbers are referenced in a wealth of station procedures. By maintaining the current program numbering, excessive administrative burden is avoided. Based on this approach, several TSTF-545 TS Bases markup pages associated with the TSTF-545 program numbering are not included in Attachment 4 of this application.
No technical variances are proposed in this amendment request. Therefore, Entergy has concluded the aforementioned variations are acceptable.
3.0 REGULATORY ANALYSIS
3.1 No Significant Hazards Consideration Analysis Entergy Operations, Inc. (Entergy), requests adoption of the Technical Specification (TS) changes described in TSTF-545, TS Inservice Testing Program Removal & Clarify SR Usage Rule Application to Section 5.5 Testing, which is an approved change to the Improved Standard Technical Specifications (ISTS), into the Waterford Steam Electric Station, Unit 3 (Waterford 3) TS. The proposed change revises the TS Chapter 6, "Administrative Controls,"
Section 6.5, "Programs to delete the "Inservice Testing Program" specification. Requirements in the Inservice Testing (IST) Program are removed, as they are duplicative of requirements in the American Society of Mechanical Engineers (ASME) Operations and Maintenance (OM) to W3F1-2016-0036 Page 4 of 6 Code, as clarified by Code Case OMN-20, Inservice Test Frequency. Note that TS Section 5.5 of NUREG 1432, Standard Technical Specifications - Combustion Engineering Plants, Revision 4, is referred to as TS Section 6.5.8 in the Waterford 3 TSs. Other requirements in Section 6.5.8 are eliminated because the Nuclear Regulatory Commission (NRC) has determined their appearance in the TS is contrary to regulations. A new defined term, Inservice Testing Program, is added, which references the requirements of Title 10 of the Code of Federal Regulations (10 CFR), Part 50, paragraph 50.55a(f). Entergy has evaluated whether or not a significant hazards consideration is involved with the proposed amendment(s) by focusing on the three standards set forth in 10 CFR 50.92, Issuance of amendment, as discussed below:
- 1. Does the proposed change involve a significant increase in the probability or consequences of an accident previously evaluated?
Response: No.
The proposed change revises TS Chapter 6, "Administrative Controls," Section 6.5, "Programs" by eliminating the "Inservice Testing Program" specification. Most requirements in the IST Program are removed, as they are duplicative of requirements in the ASME OM Code, as clarified by Code Case OMN-20, Inservice Test Frequency. The remaining requirements in the Section 6.5.8, IST Program are eliminated because the NRC has determined their inclusion in the TS is contrary to regulations. A new defined term, Inservice Testing Program, is added to the TS, which references the requirements of 10 CFR 50.55a(f).
Performance of inservice testing is not an initiator to any accident previously evaluated. As a result, the probability of occurrence of an accident is not significantly affected by the proposed change. Inservice test frequencies under Code Case OMN-20 are equivalent to the current testing period allowed by the TS with the exception that testing frequencies greater than 2 years may be extended by up to 6 months to facilitate test scheduling and consideration of plant operating conditions that may not be suitable for performance of the required testing. The testing frequency extension will not affect the ability of the components to mitigate any accident previously evaluated as the components are required to be operable during the testing period extension. Performance of inservice tests utilizing the allowances in OMN-20 will not significantly affect the reliability of the tested components. As a result, the availability of the affected components, as well as their ability to mitigate the consequences of accidents previously evaluated, is not affected.
Therefore, the proposed change does not involve a significant increase in the probability or consequences of an accident previously evaluated.
- 2. Does the proposed change create the possibility of a new or different kind of accident from any accident previously evaluated?
Response: No.
The proposed change does not alter the design or configuration of the plant. The proposed change does not involve a physical alteration of the plant; no new or different kind of equipment will be installed. The proposed change does not alter the types of inservice testing performed. In most cases, the frequency of inservice testing is unchanged.
to W3F1-2016-0036 Page 5 of 6 However, the frequency of testing would not result in a new or different kind of accident from any previously evaluated since the testing methods are not altered.
Therefore, the proposed change does not create the possibility of a new or different kind of accident from any previously evaluated.
- 3. Does the proposed change involve a significant reduction in a margin of safety?
Response: No.
The proposed change eliminates some requirements from the TS in lieu of requirements in the ASME Code, as modified by use of Code Case OMN-20. Compliance with the ASME Code is required by 10 CFR 50.55a. The proposed change also allows inservice tests with frequencies greater than 2 years to be extended by 6 months to facilitate test scheduling and consideration of plant operating conditions that may not be suitable for performance of the required testing. The testing frequency extension will not affect the ability of the components to respond to an accident as the components are required to be operable during the testing period extension. The proposed change will eliminate the existing TS Surveillance Requirement (SR) 4.0.3 (referenced as SR 3.0.3 in the ISTS) allowance to defer performance of missed inservice tests up to the duration of the specified testing frequency, and instead will require an assessment of the missed test on equipment operability. This assessment will consider the effect on a margin of safety (equipment operability). Should the component be inoperable, the Technical Specifications provide actions to ensure that the margin of safety is protected. The proposed change also eliminates a statement that nothing in the ASME Code should be construed to supersede the requirements of any TS. The NRC has determined that statement to be incorrect.
However, elimination of the statement will have no effect on plant operation or safety.
Therefore, the proposed change does not involve a significant reduction in a margin of safety.
Based on the above, Entergy concludes that the proposed change presents no significant hazards consideration under the standards set forth in 10 CFR 50.92(c), and, accordingly, a finding of "no significant hazards consideration" is justified.
4.0 ENVIRONMENTAL EVALUATION The proposed change would change a requirement with respect to installation or use of a facility component located within the restricted area, as defined in 10 CFR 20, or would change an inspection or surveillance requirement. However, the proposed change does not involve (i) a significant hazards consideration, (ii) a significant change in the types or significant increase in the amounts of any effluents that may be released offsite, or (iii) a significant increase in individual or cumulative occupational radiation exposure. Accordingly, the proposed change meets the eligibility criterion for categorical exclusion set forth in 10 CFR 51.22(c)(9).
Therefore, pursuant to 10 CFR 51.22(b), no environmental impact statement or environmental assessment need be prepared in connection with the proposed change.
to W3F1-2016-0036 Page 6 of 6 5.0 PRECEDENCE Because TSTF-545, Revision 3, was approved by the NRC in December 2015, time has not permitted licensees to apply, and gain approval for, adoption of TSTF-545. Therefore, other than TSTF-545 itself, no other precedence exists at this time.

BASES (DRN 03-524)
Some examples of this process are:
- a. Emergency feedwater (EFW) pump turbine maintenance during refueling that requires testing at steam pressures > 750 psig. However, if other appropriate testing is satisfactorily completed, the EFW System can be considered OPERABLE. This allows startup and other necessary testing to proceed until the plant reaches the steam pressure required to perform the testing.
- b. High pressure safety injection (HPSI) maintenance during shutdown that requires system functional tests at a specified pressure. Provided other appropriate testing is satisfactorily completed, startup can proceed with HPSI considered OPERABLE. This allows operation to reach the specified pressure to complete the necessary post maintenance testing.
³(DRN 03-524)
Specification 4.0.2 establishes the limit for which the specified time interval for Surveillance Requirements may be extended. It permits an allowable extension of the normal surveillance interval to facilitate surveillance scheduling and consideration of plant operating conditions that may not be suitable for conducting the surveillance; e.g., transient conditions or other ongoing surveillance or maintenance activities. It also provides flexibility to accommodate the length of a fuel cycle for surveillances that are performed at each refueling outage and are specified with an 18-month surveillance interval. It is not intended that this provision be used repeatedly as a convenience to extend surveillance intervals beyond that specified for surveillances that are not performed during refueling outages. The limitation of Specification 4.0.2 is based on engineering judgment and the recognition that the most probable result of any particular surveillance being performed is the verification of conformance with the Surveillance Requirements. This provision is sufficient to ensure that the reliability ensured through surveillance activities is not significantly degraded beyond that obtained from the specified surveillance interval.
The exceptions to SR 4.0.2 are those Surveillances for which the 25% extension of the interval specified in the Frequency does not apply. These exceptions are stated in the individual Specifications. The requirements of regulations take precedence over the TS. Examples of where SR 4.0.2 does not apply are in the Containment Leakage Rate Testing Program required by 10 CFR 50, Appendix J, and the inservice testing of pumps and valves in accordance with applicable American Society of Mechanical Engineers Operation and Maintenance Code, as required by 10 CFR 50.55a. These programs establish testing requirements and Frequencies in accordance with the requirements of regulations. The TS cannot, in and of themselves, extend a test interval specified in the regulations directly or by reference.
When a Section 6.8, Programs and Manuals, specification states that the provisions of SR 4.0.2 are applicable, a 25% extension of the testing interval, whether stated in the specification or incorporated by reference, is permitted.
This extension allowed by Specification 4.0.2 is also applicable to Surveillance Requirements required in Technical specification Actions. However, the extension does not apply to the initial performance. The extension only applies to each performance after the initial performance. The initial performance required by the Action, whether it is a particular Surveillance or some other remedial action, is considered a single action with a single completion time. One reason for not allowing the extension to this completion time is that such WATERFORD - UNIT 3 B 3/4 0-5 AMENDMENT NO. 99 CHANGE NO. 23
BASES an action usually verifies that no loss of function has occurred or accomplishes the function of the inoperable equipment in an alternative manner.
Specification 4.0.3 establishes the flexibility to defer declaring affected equipment inoperable or an affected variable outside the specified limits when a Surveillance has not been completed within its specified interval. A delay period of up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or up to the limit of the specified surveillance interval, whichever is greater, applies from the point in time that it is discovered that the Surveillance has not been performed in accordance with Specification 4.0.2, and not at the time that the specified interval was not met.
This delay period provides an adequate time to complete Surveillances that have been missed. This delay period permits the completion of a Surveillance before complying with required actions or other remedial measures that might preclude completion of the Surveillance.
The basis for this delay period includes consideration of unit conditions, adequate planning, availability of personnel, the time required to perform the Surveillance, the safety significance of the delay in completing the required Surveillance, and the recognition that the most probable result of any particular Surveillance being performed is the verification of conformance with the requirements. When a Surveillance with an interval based not on time intervals, but upon specified unit conditions, operational situations, or requirements of regulations (e.g., prior to entering MODE 1 after each fuel loading, or in accordance with 10 CFR 50, Appendix J, as modified by approved exemptions, etc. is discovered to not have been performed when specified, Specification 4.0.3 allows for the full delay period of up to the specified interval to perform the Surveillance. However, since there is not a time interval specified, the missed Surveillance should be performed at the first reasonable opportunity. Specification 4.0.3 provides a time limit for, and allowances for the performance of, Surveillances that become applicable as a consequence of MODE changes imposed by required actions.
When a Section 6.8, Programs and Manuals, specification states that the provisions of SR 4.0.3 are applicable, it permits the flexibility to defer declaring the testing requirement not met in accordance with SR 4.0.3 when the testing has not been completed within the testing interval (including the allowance of SR 4.0.2 if invoked by the Section 6.8 specification).
Failure to comply with specified intervals for surveillance requirements is expected to be an infrequent occurrence. Use of the delay period established by Specification 4.0.3 is a flexibility which is not intended to be used as an operational convenience to extend Surveillance intervals.
While up to 24 hours2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> or the limit of the specified interval is provided to perform the missed Surveillance, it is expected that the missed Surveillance will be performed at the first reasonable opportunity. The determination of the first reasonable opportunity should include consideration of the impact on plant risk (from delaying the Surveillance as well as any plant configuration changes required or shutting the plant down to perform the Surveillance) and impact on any analysis assumptions, in addition to unit conditions, planning, availability of personnel, and the time required to perform the Surveillance.
WATERFORD - UNIT 3 B 3/4 0-6 AMENDMENT NO. 99 CHANGE NO. 23
BASES This risk impact should be managed through the program in place to implement 10 CFR 50.65(a)(4) and its implementation guidance, NRC Regulatory Guide 1.182, 'Assessing and Managing Risk Before Maintenance Activities at Nuclear Power Plants.' This Regulatory Guide addresses consideration of temporary and aggregate risk impacts, determination of risk management action thresholds, and risk management action up to and including plant shutdown.
The missed Surveillance should be treated as an emergent condition as discussed in the Regulatory Guide. The risk evaluation may use quantitative, qualitative, or blended methods.
The degree of depth and rigor of the evaluation should be commensurate with the importance of the component. Missed Surveillances for important components should be analyzed quantitatively. If the results of the risk evaluation determine the risk increase is significant, this evaluation should be used to determine the safest course of action. All missed Surveillances will be placed in the licensee's Corrective Action Program.

When the plant enters Mode 3 during a plant startup coming out of an outage, there is insufficient steam pressure to complete the dynamic final calibration of the governor valve speed control unit of the turbine-driven EFW pump. In this condition, the turbine-driven EFW pump is available (i.e., there is a reasonable expectation that once sufficient steam pressure is available to the turbine-driven EFW pump turbine, it will be able to successfully complete the quarterly IST and 18 month EFAS surveillance requirements to fully demonstrate operability). Although the turbine-driven EFW pump does not have sufficient steam pressure to complete dynamic final calibration of the governor valve speed control unit, the turbine-driven EFW pump still maintains performance capability (albeit at a potentially reduced flow performance based upon governor valve speed control unit settings) to provide the system safety function of cooling the plant to shutdown cooling entry conditions. This exception does not allow Mode 3 to be entered during a plant startup while performing maintenance activities that cause the turbine driven EFW pump to be unavailable.
The safety function of the EFW System to ensure the Reactor Coolant System can be cooled to shutdown cooling system entry conditions continues to be met under all plant conditions and for the worst case postulated accident from the point in time when the plant enters Mode 3 during the plant startup with the inoperable turbine-driven EFW pump through the point in time when the turbine-driven EFW pump is restored to OPERABLE condition.

Prior to entry into Mode 2, surveillance requirement testing of various combinations of EFW pumps and valves will ensure ALL required EFW system flow paths and equipment (including the turbine-driven EFW pump as previously described in second paragraph of this section of the bases) are demonstrated operable before the core is taken critical and significant heat is generated.

Surveillance Requirements
- a. Verifying the correct alignment for manual, power operated, and automatic valves in the EFW water and steam supply flow paths provides assurance that the proper flow paths exist for EFW operation. This Surveillance Requirement (SR) does not apply to valves that are locked, sealed, or otherwise secured in position, since these valves are verified to be in the correct position prior to locking, sealing, or securing. This SR also does not apply to valves that cannot be inadvertently misaligned, such as check valves. This SR does not require any testing or valve manipulation; rather, it involves verification that those valves capable of potentially being mispositioned are in the correct position.

- b. The SR to verify pump OPERABILITY pursuant to the Inservice Testing Program INSERVICE TESTING PROGRAM ensures that the requirements of ASME Code Section XI are met and provides reasonable assurance that the pumps are capable of satisfying the design basis accident flow requirements. Because it is undesirable to introduce cold EFW into the steam generators while they are operating, testing is typically performed on recirculation flow. Such in-service tests confirm component OPERABILITY, trend performance, and detect incipient failures by indicating abnormal performance.
<(DRN 03-1807, Ch. 30)
This SR is modified to indicate the SR should be deferred until suitable test conditions have been established. This deferral is required because there is an insufficient steam pressure to perform post maintenance activities which may need to be completed prior to performing the required turbine-driven pump SR. This deferral allows the unit to transition from MODE 4 to MODE 3 prior to the performance of the SR and provides a 24 hour2.777778e-4 days <br />0.00667 hours <br />3.968254e-5 weeks <br />9.132e-6 months <br /> period once a steam generator pressure of 750 psig is reached to complete the required post maintenance activities and SR.

The SR for actuation testing ensures that EFW can be delivered to the appropriate steam generator in the event of any accident or transient that generates EFAS and/or MSIS signals, by demonstrating that each automatic valve in the flow path actuates to its correct position and that the EFW pumps will start on an actual or simulated actuation signal. This Surveillance covers the automatic flow control valves, automatic isolation valves, and steam admission valves but is not required for valves that are locked, sealed, or otherwise secured in the required position under administrative controls.

The 8 second required closure time includes a 1 second allowance for instrument response time.
This SR is normally performed during a refueling outage but may be performed upon returning the unit to operation following a refueling outage. The MSlVs should not be tested at power since even a part stroke exercise increases the risk of a valve closure with the unit generating power. As the MSIVs are not tested at power, they are exempt from the ASME Code, Section Xl (lnservice Inspection, Article IWV-3400), requirements during operation in MODES 1 and 2.

³(DRN 03-1737, Ch. 31) 3/4.7.1.6 MAIN FEEDWATER ISOLATION VALVES The Main Feedwater Isolation Valves (MFIVs) isolate main feedwater (MFW) flow to the secondary side of the steam generators following a high energy line break (HELB). Closure of the MFIVs terminates flow to both steam generators, mitigating the consequences for feedwater line breaks (FWLBs). Closure of the MFIVs effectively terminates the addition of main feedwater to an affected steam generator, limiting the mass and energy release for Main Steam Line Breaks (MSLBs) or FWLBs inside containment, and reducing the cooldown effects for MSLBs.
The MFIVs isolate the non-safety related feedwater supply from the safety related portion of the system. In the event of a secondary side pipe rupture inside containment, the valves limit the quantity of high energy fluid that enters containment through the break, and provide a pressure boundary for the controlled addition of Emergency Feedwater (EFW) to the intact steam generator.

One MFIV is located on each MFW line, outside, but close to, containment. The MFIVs are located upstream of the EFW injection point so that EFW may be supplied to a steam generator following MFIV closure.

The TS is annotated with a 3.0.4 exemption, allowing entry into the applicable MODES to be made with an inoperable MFIV closed or isolated as required by the ACTIONS. The ACTIONS allow separate condition entry for each valve by using AWith one or more MFIV...@.
This prevents immediate entry into TS 3.0.3 if both MFIVs are declared inoperable.

The Surveillance Requirement to verify isolation in less than or equal to 6 seconds is based on the time assumed in the accident and containment analyses. The design basis correlates a static test utilizing one accumulator to demonstrate the ability of the MFIVs to close in less than or equal to 6 seconds under design basis accident conditions with two accumulators.
The static stroke time test that utilizes one accumulator is allowed to exceed the 6 second Surveillance Requirement since both accumulators are credited in the design basis Accidents in order to isolate within the 6 second Surveillance Requirement. The 6 second required closure time includes a 1 second allowance for instrument response time.
>> (DRN 05-1650)
The MFIVs should not be tested at power since even a partial stroke exercise increases the risk of a valve closure with the plant generating power and would create added cyclic stresses. The Surveillance to verify each MFIV can close on an actual or simulated actuation signal is normally performed when the plant is returning to operation following a refueling outage.
Verification of valve closure on an actuation signal is not required until entry into Mode 3 consistent with TS 3.3.2. The 18 month frequency is based on the refueling cycle. Verification of closure time is performed per the Inservice Testing Program INSERVICE TESTING PROGRAM This frequency is acceptable from a reliability standpoint and is in accordance with the Inservice Testing Program INSERVICE TESTING PROGRAM.

Credited Non-Safety Related Support Systems for MFIV Operability Reactor Trip Override (RTO) and the Auxiliary Feedwater (AFW) Pump High Discharge Pressure Trip (HDPT) are credited for rapid closure of the Main Feedwater Isolation Valves (MFIVs) during main steam and feedwater line breaks. Crediting of these non-safety features was submitted to the NRC as a USQ and approved. (Reference letter dated September 5, 2000 from the NRC to Charles M. Dugger, AWaterford 3 Steam Electric Station, Unit 3 - Issuance of Amendment RE: Addition of Main Feedwater Ioslation Valves to Technical Specifications and Request for NRC Staff Review of an Unreviewed Safety Question.@)
The feature of RTO that is credited for MFIV closure is the rapid SGFP speed reduction upon reactor trip initiation. This feature reduces the differential pressure across the valve disc at closure, thus allowing rapid valve closure. Therefore, the RTO feature must be able to decrease SGFP speed to minimum on a reactor trip during SGFP operation for OPERABILITY of the MFIVs.
The AFW Pump HDPT reduces the differential pressure across the valve disc at closure during AFW Pump operation. Therefore, this feature must be functional during AFW Pump operation for OPERABILITY of the MFIVs. When the AFW pump is not running, this trip is not required.
In MODES 1, 2, 3, and 4, the MFIVs are required to be OPERABLE. Because the MFIVs are required to be OPERABLE in MODES 1, 2, 3, and 4, RTO must be able to decrease SGFP

If RTO is unable to decrease running SGFP(s) speed to minimum on a reactor trip with the SGFPs running, both MFIVs must be declared INOPERABLE, and Technical Specification 3.7.1.6 must be entered. If the AFW Pump HDPT is non-functional with the AFW pump running, the AFW pump should be secured immediately or both MFIVs must be declared INOPERABLE, and Technical Specification 3.7.1.6 must be entered.
RTO and AFW Pump HDPT Test Requirements The RTO and AFW pump high pressure trip are subjected to a testing program similar to comparable safety related instrumentation to provide assurance of the reliability of these non-safety related functions credited to support the MFIV safety related closure function.
(DRN 03-1807, Ch. 30)
The testing requirements for the RTO credited function should demonstrate the ability of RTO to reduce SGFP speed upon an actual or simulated actuation signal. The test requirements do not require timing the response because in the limiting FWLB scenario, RTO is required for compliance with a 5 second Technical Specification closure; however, the containment analyses allow longer closure times during this event. Even if RTO were to fail, the MFIV would eventually close as the pressure across the valve equalizes to the available actuator thrust, the nitrogen pressure equalizes, and finally as the SGFP speed reduces due to a loss of steam after the MSIV closes. The expected maximum closure time would be less than one minute due to SGFP speed decrease. This phenomenon would act to close the valve within the appropriate time to preserve the safety function. The RTO feature should not be tested at power since it increases the risk of a feedwater transient with the plant generating power, but should normally be performed when the plant is returning to operation following a refueling outage. The testing criteria shall verify functionality of the RTO system, with SGFP pump response, by verifying that the feedwater control system sends the control signal corresponding to minimum speed to the pump upon an actual or simulated RTO signal at least once per 18 months. The functionality of the RTO system shall be verified through the performance of Instrumentation & Controls functional test procedure, AFunctional Test of Reactor Trip Override, High Level Override, and Level Channel Deviation FWCS.@ The 18 month frequency is based on the refueling cycle, similar to testing performed per the Inservice Testing Program INSERVICE TESTING PROGRAM.

(DRN 04-1243, Ch. 38) 3/4.7.1.7 ATMOSPHERIC DUMP VALVES (ADVs)
Two ADVs are provided, one per steam generator. The ADVs are provided with upstream block valves to permit their being tested at power, and to provide an alternate means of isolation.
The ADVs are equipped with pneumatic controllers to permit control of the cooldown rate. The ADVs are provided with a pressurized nitrogen gas supply that, on a loss of pressure in the normal instrument air supply, automatically supplies nitrogen to operate the ADVs. The ADVs can also be operated manually once the nitrogen gas supply is depleted.
The ADVs provide a safety grade method for cooling the unit to Shutdown Cooling (SDC)
System entry conditions, should the preferred heat sink via the Steam Bypass System to the condenser not be available, as discussed in the FSAR, Section 10.3. This is done in conjunction with the Emergency Feedwater System providing cooling water from the condensate storage pool (CSP) to meet Branch Technical Position (BTP) RSB 5-1.
The automatic operation of the ADVs to open is assumed in the Small Break LOCA (SBLOCA) analysis at power levels above 70% RATED THERMAL POWER. ADVs are credited for SBLOCA analysis to lower steam generator secondary side pressures, compared to crediting only MSSVs, and thus provide increased cooling of the RCS. This results in a lower calculated peak cladding temperature (PCT) for SBLOCA ECCS analysis.
Analysis has shown that automatic operation of the ADV is not required when the unit is at or below 70% RATED THERMAL POWER for greater than six hours because, based on decay heat load, one high-pressure safety injection train is capable of mitigating the SBLOCA event. At greater than 70% RATED THERMAL POWER, one high-pressure safety injection train and one ADV, in automatic, are capable of mitigating the SBLOCA event. Therefore, the ADVs, in automatic, are required at greater than 70% RATED THERMAL POWER and for six hours after reducing power to less than or equal to 70% RATED THERMAL POWER.
Limiting Condition for Operation The LCO requires that each ADV be OPERABLE.
The ADV manual controls must be OPERABLE in MODES 1, 2, 3, and 4 to allow operator action needed for decay heat removal and safe shutdown in accordance with BTP RSB 5-1.

- a. To mitigate the SBLOCA event, the ADVs must automatically open at a pressure of less than or equal to 1040 psia (992 psig indicated). This Surveillance Requirement (SR) ensures that the ADV controllers are in automatic and set at an appropriate setpoint that is bounded by the SBLOCA safety analysis. The setpoint must be verified using the plant monitoring computer or appropriate maintenance and test equipment. This SR need not be performed when the ADV automatic actuation channels are not required to be OPERABLE per the LCO footnote.
- b. To perform a controlled cooldown of the reactor coolant system, the ADVs must be able to be opened and throttled through their full range. Additionally, the ADV must be capable of being closed to fulfill its secondary function of containment isolation. This SR ensures the ADVs are tested through a full control cycle. The test interval is in accordance with the Inservice Testing Program INSERVICE TESTING PROGRAM.
- c. The SR to calibrate the ADV automatic actuation channels ensures that the system will generate an actuation signal at 1040 psia (992 psig indicated) as assumed for the SBLOCA. The calibration should include the plant monitoring computer points used to set the setpoint.
- d. The SR for actuation testing ensures that the ADV will automatically open on a high steam pressure signal, with a response time of less than or equal to 60 seconds, as assumed for the SBLOCA. Credit may be taken for an actual or simulated actuation signal.
³(DRN 04-1243, Ch. 38) 3/4.7.2 STEAM GENERATOR PRESSURE/TEMPERATURE LIMITATION The limitation on steam generator secondary pressure and temperature ensures that the pressure induced stresses in the steam generators do not exceed the maximum allowable fracture toughness stress limits. The limitation to 115°F and 210 psig is based on a steam generator RTNDT of 40°F and is sufficient to prevent brittle fracture. Below this temperature of 115°F the system pressure must be limited to a maximum of 20% of the secondary hydrostatic test pressure of 1375 psia (corrected for instrument error). Should steam generator temperature drop below 115°F an engineering evaluation of the effects of the overpressurization is required.
However, to reduce the potential for brittle failure the steam generator temperature may be increased to a limit of 200°F while performing the evaluation. The limitations on the primary side of the steam generator are bounded by the restrictions on the reactor coolant system in Specification 3.4.8.1.
3/4.7.3 COMPONENT COOLING WATER AND AUXILIARY COMPONENT COOLING WATER SYSTEMS The OPERABILITY of the component cooling water system and its corresponding auxiliary component cooling water system ensures that sufficient cooling capacity is available for continued operation of safety-related equipment during normal and accident conditions. The redundant cooling capacity of these systems, assuming a single failure, is consistent with the assumptions used in the safety analyses.

Attachment 5 to W3F1-2016-0036 Description and Assessment of the Proposed Alternative to the ASME Code to W3F1-2016-0036 Page 1 of 3 DESCRIPTION AND ASSESSMENT OF THE PROPOSED ALTERNATIVE TO THE ASME CODE Request in Accordance with 10 CFR 50.55a(z)(2)
Alternative Due To Hardship Without a Compensating Increase in Quality and Safety
1.0 DESCRIPTION
The request is to adopt a proposed alternative to the American Society of Mechanical Engineers (ASME) Operation and Maintenance (OM) Code by adoption of approved Code Case OMN-20, "Inservice Test Frequency."
2.0 ASSESSMENT Technical Evaluation of the Proposed Alternative to the OM Code Section IST of Division 1 of the OM Code, which is incorporated by reference in 10 CFR 50.55a(a), specifies component test frequencies based either on elapsed time periods (e.g.,
quarterly, 2 years) or on the occurrence of a plant condition or event (e.g., cold shutdown, refueling outage).
ASME Code Case OMN-20, Inservice Test Frequency, has been approved for use by the ASME OM committee as an alternative to the test frequencies for pumps and valves specified in ASME OM Division: 1 Section IST 2009 Edition through OMa-2011 Addenda, and all earlier editions and addenda of ASME OM Code.
Code Case OMN-20 is not referenced in the latest revision of Regulatory Guide 1.192 (August 2014) as an acceptable OM Code Case to comply with 10 CFR 50.55a(f) requirements as allowed by 10 CFR 50.55a(b)(6). The proposed alternative is to use Code Case OMN-20 to extend or reduce the IST frequency requirements for the third10-year IST interval or until OMN-20 is incorporated into the next revision of Regulatory Guide 1.192.
ASME Code Components Affected The Code Case applies to pumps and valves specified in ASME OM Division: 1 Section IST 2009 Edition through OMa-2011 Addenda and all earlier editions and addenda of ASME OM Code. Frequency extensions may also be applied to accelerated test frequencies (e.g., pumps in Alert Range) as specified in OMN-20.
For pumps and valves with test periods of 2 years of less, the test frequency allowed by OMN-20 and the current Technical Specification (TS) Inservice Testing Program (as modified by SR 3.0.2 and EGM 2012-001) are the same. For pumps and valves with test frequencies greater than 2 years, OMN-20 allows the test frequency to be extended by 6 months. The current TS Inservice Testing (IST) Program does not allow extension of test frequencies that are greater than 2 years.

Applicable Code Edition and Addenda
ASME Code Case OMN-20 applies to ASME OM Division: 1 Section IST 2009 Edition through OMa-2011 Addenda and all earlier editions and addenda of ASME OM Code.
The Waterford Electric Generating Plant, Unit 3 (Waterford 3) Code Edition and Addenda that are applicable to the program interval are the ASME OM Code 2001 Edition with addenda through and including the ASME OMb Code-2003 Adenda (referred to as OMB-2003)
(reference Entergy Letter GNRI-96/00184) dated August 27, 1996, TAC M94454, Inservice Testing Plan (ADAMS Accession No. ML073410350). The Waterford 3 current interval ends November 30, 2017.
Applicable Code Requirement
This request is made in accordance with 10 CFR 50.55a(z)(2), and proposes an alternative to the requirements of 10 CFR 50.55a(f), which requires pumps and valves to meet the test requirements set forth in specific documents incorporated by reference in 10 CFR 50.55a(a).
ASME Code Case OMN-20 applies to Division 1, Section IST of the ASME OM Code and associated addenda incorporated by reference in 10 CFR 50.55a(a).
Reason for Request
NOTE: The discussions within this request for alternative refer to NUREG 1432, Standard Technical Specifications - Combustion Engineering Plants, Revision 4, SR numbering. The equivalent Waterford 3 SRs are 4.0.2 and 4.0.3.
The IST Program controls specified in Section 6.5.8 of the Waterford 3 TS provide: a) a table specifying certain IST frequencies; b) an allowance to apply SR 4.0.2 to inservice tests required by the OM Code and with frequencies of two years or less; c) an allowance to apply SR 4.0.3 to inservice tests required by the OM Code; and d) a statement that, Nothing in the ASME OM Code shall be construed to supersede the requirements of any TS. In Regulatory Issue Summary (RIS) 2012-10, "NRC Staff Position on Applying Surveillance Requirement 3.0.2 and 3.0.3 to Administrative Controls Program Tests," and Enforcement Guidance Memorandum (EGM) 2012-001, "Dispositioning Noncompliance with Administrative Controls Technical Specifications Programmatic Requirements that Extend Test Frequencies and Allow Performance of Missed Tests," the NRC stated that items b, c, and d of the TS IST Program were inappropriately added to the TS and may not be applied (although the EGM allows licensees to continue to apply those paragraphs pending a generic resolution of the issue).
In RIS 2012-10 and EGM 2012-001, the NRC stated that the current TS allowance to apply Surveillance Requirements (SR) 3.0.2 and SR 3.0.3 to the IST Program would no longer be permitted. In response, OMN-20, which provides allowances similar to SR 3.0.2, was approved and is proposed to be used as an alternative to the test periods specified in the OM code. The proposed alternative substitutes an approved Code Case for the existing TS requirements that the NRC has determined are not legally acceptable as a TS allowance. This proposed alternative provides an equivalent level of safety as the existing TS allowance, while maintaining consistency with 10 CFR 50.55a and the ASME OM Code.
to W3F1-2016-0036 Page 3 of 3 Proposed Alternative and Basis for Use The proposed alternative is OMN-20, "Inservice Test Frequency," which addresses testing periods for pumps and valves specified in ASME OM Division 1, Section IST, 2009 Edition through OMa-2011 Addenda, and all earlier editions and addenda of ASME OM Code.
This request is being made in accordance with 10 CFR 50.55a(z)(2), in that the existing requirements are considered a hardship without a compensating increase in quality and safety for the following reasons:
- 1) For IST testing periods up to and including 2 years, Code Case OMN-20 provides an allowance to extend the IST testing periods by up to 25%. The period extension is to facilitate test scheduling and considers plant operating conditions that may not be suitable for performance of the required testing (e.g., performance of the test would cause an unacceptable increase in the plant risk profile due to transient conditions or other ongoing surveillance, test or maintenance activities). Period extensions are not intended to be used repeatedly merely as an operational convenience to extend test intervals beyond those specified. The test period extension and the statements regarding the appropriate use of the period extension are equivalent to the existing TS SR 3.0.2 allowance and the statements regarding its use in the SR 3.0.2 Bases. Use of the SR 3.0.2 period extension has been a practice in the nuclear industry for many decades and elimination of this allowance would place a hardship on Entergy Operations, Inc. (Entergy), when there is no evidence that the period extensions affect component reliability.
- 2) For IST testing periods of greater than 2 years, OMN-20 allows an extension of up to 6 months. The ASME OM Committee determined that such an extension is appropriate.
The 6-month extension will have a minimal impact on component reliability considering that the most probable result of performing any inservice test is satisfactory verification of the test acceptance criteria. As such, pumps and valves will continue to be adequately assessed for operational readiness when tested in accordance with the requirements specified in 10 CFR 50.55a(f) with the frequency extensions allowed by Code Case OMN-20.
- 3) As stated in EGM 2012-001, if an inservice test is not performed within its frequency, SR 4.0.3 will not be applied. The effect of a missed inservice test on the operability of TS equipment will be assessed under the licensee's Operability Determination Program.
Duration of Proposed Alternative The proposed alternative is requested for the current 10-year IST interval or until Code Case OMN-20 is incorporated into a future revision of Regulatory Guide 1.192, referenced by a future revision of 10 CFR 50.55a, whichever occurs first.
Precedents The NRC approved the use of OMN-20 for North Anna on March 27, 2014 (NRC ADAMS Accession Number ML14084A407).
