1.0 INTRODUCTION
1.1 Purpose This procedure represents the Watts Bar Nuclear Plant (WBN) Augmented Inservice Testing (AIST) Program developed to assess the operational readiness of components important to safety which are not included in scope of the WBN Inservice Testing Program (0-TI-100.006).
Development and implentation of the AIST Program is mandated by TVA corporate fleet-wide procedure NPG-SPP-09.1. This requirement is used to implement the requirements of testing non-Code Class safety related components in accordance with 10 CFR 50.55a(f)(4) and 10 CFR 50.55a(f)(6)(ii). In addition, the AIST Program incorporates a portion of the requirements of Code of Federal Regulations, Title 10, Part 50, Appendix B (10CFR50, Appendix B).
1.2 Scope The AIST Program establishes the testing and examination requirement to assess operational readiness of certain Non-Code Class components important to nuclear safety.
These requirements apply to:
A. Pumps and valve required to perform a specific function in shutting down the reactor to safe shutdown condition, in maintaining the safe shutdown condition, or in mitigating the consequences of an accident; B. Pressure relief devices that protect systems or portions of systems that perform one or more of these functions.
C. Dynamic restraints (snubbers) used in systems that perform one or more of these three functions, or to ensure the integrity of the reactor coolant pressure boundary. Snubbers which meet this requirement are curently listed in 0-TI-100.006.
Both WBN units are licensed as Hot Standby (Mode 3) for the safe shutdown condition.
Additional components may be included in scope of the AIST program at the discretion of the WBN IST engineer.
See 0-TI-100.016 Appendix E for further information on how the scope of the AIST Program is determined.
WBN - Unit 0 Augmented Inservice Testing Program 0-TI-100.007 Rev. 0002 Page 5 of 51 1.3 Guidelines for Augmented Inservice Testing Requirements 1.3.1 Code of Record The AIST Program complies with the American Society of Mechanical Engineers (ASME)
Code for Operation and Maintenance of Nuclear Power Plants (OM Code), 2004 Edition through 2006 Addenda and 10CFR50.55a to the extent practical.
In cases where compliance with the OM Code is impractical, appropriate alternative test requirements will be assigned and an alternative test justification will be used to document the impracticality and alternative test requirements. The alternative test justifications may be used as soon as they are incorporated in the AIST Program and there is no requirement to seek approval from an outside agency or regulator. This meets the requirement of 10CFR 50.55a.
1.3.2 NUREG-1482 The NRC published NUREG-1482, Guidelines for Inservice Testing at Nuclear Power Plants, to provide licensees guidance and recommendations for developing and implementing IST Programs. It is recognized that this document does not contain any requirements. However, the guidance provided was used in development of the WBN AIST Program where applicable.
1.3.3 Code Cases In accordance with 10CFR50.55a, paragraph (b)(6), code cases referenced in Regulatory Guide (RG) 1.192, Operation and Maintenance Code Case Acceptability, ASME OM
- Code, may be used without prior NRC approval subject to the requirements of (b)(6)(i) through (b)(6)(iii). WBN has elected to adopt the code cases listed below that are approved for use in RG 1.192 for WBN 1 and 2. Actual implementation will be on an as-needed basis.
OMN-13, R2; Performance-Based Requirements for Extending Snubber Inservice Visual Examination Interval at LWR Power Plants OMN-16, R1; Use of a Pump Curve for Testing OMN-17; Alternative Rules for Testing ASME Class 1 Pressure Relief/Safety Valves OMN-18; Alternate Testing Requirements for Pumps Testing Quarterly Within 20% of Design Flow OMN-19; Alternative Upper Limit for the Comprehensive Pump Test OMN-20; Inservice Test Frequency 1.4 Applicability This procedure is applicable to WBN Units 0, 1, and 2 components determined to meet the scoping requirements of 10CFR50.55a and the ASME OM Code.

0-MI-0.011, Safety/Relief Valve 3.0 PROGRAM DEVELOPMENT 3.1 Development of Program Scope The methodology used to develop the scope for the WBN AIST Program is similar to the approach used for the IST Program and is described below.
A. TVA upper tier procedures NPG-SPP-09.1 and NPG-SPP-09.1 series were used in development of the WBN AIST Program.
B. The components considered for inclusion in scope of the AIST Program were those Non-Code Class equivalent components that perform a specific function in shutting down the reactor to safe shutdown condition, in maintaining the safe shutdown condition, or in mitigating the consequences of an accident. This includes pressure relief devices that protect systems or portions of systems that perform one or more of these functions, and dynamic restraints (snubbers) used in systems that perform one or more of these functions or that ensure the integrity of the reactor coolant pressure boundary.
C. The WBN drawings listed in Section 3.2 were used to identify the non-ASME Code Class 1, 2, and 3 components.
D. The Final Safety Analysis, Technical Specifications and Bases (Unit 1 and 2),
Technical Requirements Manual and Bases (Unit 1 and 2), and all System Description Documents (SDDs) were reviewed to determine the nuclear safety related functions credited at WBN.
E. The function(s) of each component within the Non-Code Class boundaries shown on the system flow drawings were reviewed if they existed for the system. Based on this review, each component was determined to be in scope or exempt from scope of the Code of Record (ASME OM Code, 2004 Edition through 2006 Addenda). The component functions and scope determination are documented in 0-TI-100.016, Augmented Inservice Testing Program Bases Document.

WBN - Unit 0 Augmented Inservice Testing Program 0-TI-100.007 Rev. 0002 Page 10 of 51 3.3 Development of Component Test Requirements The methodology used to determine test requirements components in scope of the WBN AIST Program is described below.
A. Each component in scope of the program was categorized in accordance with OM Code, ISTB-1300 and ISTC-1300 (SPP-09.1.20). The OM Code categories are modified with an "-Aug" suffix to designate the component to subject AIST Program test requirements.
B. The test requirements for each pump were determined in accordance with OM Code, Table ISTB-3000-1 and ISTB-3400 (SPP-09.1.20) as applicable for the pump category.
C. The test requirements for each valve and pressure relief device were determined in accordance with OM Code, Table ISTC-3500-1 and ISTC 3510 (SPP-09.1.20).
D. In cases where it is not practicable to perform pump and valve testing in accordance with OM Code (SPP-09.1 series) requirements, appropriate alternative test method(s) are selected and documented in Attachments 3 & 4, Alternative Test Justifications.
E. In cases where it is not practicable to perform valve testing on a quarterly frequency, an alternative test frequency is selected in accordance with the OM Code for deferring valve test frequency and documented in Attachment 5, Deferred Test Justifications.
F.
The specifc test requirements (test type and frequency) for pumps, valves, and pressure relief devices in scope of the AIST Program are shown in Attachment 1, Augmented Pump Test Plan, and Attachment 2, Augmented Valve Test Plan. An explanation of the abbreviations used in these appendices is provided in Section 3.3 and Section 3.4. Specific information regarding alternative tests and frequencies are provided in Attachments 3 & 4, Alternative Test Justifications, and Attachment 5, Deferred Test Justifications. The Notes column of Attachments 1 and 2 provides reference to the applicable alternative test justification or deferred test justification.
G. The preservice test requirements for U2 valves and pressure relief devices are the first performance of the inservice tests listed in Attachment 2. The preservice test requirement for U2 pumps is not the same as the inservice test requirements listed in. The preservice test establishes a five point pump curve and initial reference values as described in SPP-09.1.20. The preservice pump test is not listed in Attachment 1 because it is a one time only test for each pump.

WBN - Unit 0 Augmented Inservice Testing Program 0-TI-100.007 Rev. 0002 Page 21 of 51 4.0 STRUCTURE OF AIST PROGRAM REQUIREMENTS The diagram below provides a graphic representation of the hierachy and struture of various regulations and requirements related to the WBN AIST Program. The relationships depicted in this diagram are described in the following subsections.
WBN - Unit 0 Augmented Inservice Testing Program 0-TI-100.007 Rev. 0002 Page 22 of 51 4.1 Upper Tier Requirements for AIST Program Scope and Content Section 1.3.1 of this procedure clarifies there are no specific federal regulations which mandate the AIST Program. Furthermore, 10CFR50, Appendix B only provides a general requirement to established a test program, but it does not identify specific test requirements or codes and standards which the test program shall comply TVA corporate fleet-wide procedure NPG-SPP-09.1 provides the TVA requirement to develop and implement an AIST Program. WBN has elected to comply with the ASME OM Code, 2004 Edition through 2006 Addenda, to the extent practical.
The following TVA corporate fleet-wide procedures provide the TVA procedure equivalent of the OM Code applicable to the WBN AIST Program. Content of the AIST Program (e.g., test type, test frequency, pump/valve test plan tables, test deferral justifications, etc.) was developed in accordance with these procedures (OM Code).
Procedure Description SPP-09.1.20 Procedure eqivalent of OM Code, Subsections:
ISTA - General Requirements ISTB - Pumps ISTC - Valves ISTD - Snubbers SPP-09.1.21 This procedure addresses specific requirements in SPP-09.1.20 (OM Code Subsections ISTB and ISTC) related to reference values and acceptance criteria. It provides the technical and administrative process for performing component evaluations and establishing new reference valves and associated acceptance criteria.
SPP-09.1.22 This procedure addresses specific requirements in SPP-09.1.23 (OM Code Subsections ISTB and ISTC) related to component trending. It provides the requirements for periodic performance trending.
SPP-09.1.23 Provides requirements for evaluation of potential preconditioning activities affecting AIST required tests.
SPP-09.1.24 Procedure eqivalent of OM Code, Appendix I - Pressure Relief Devices. This procedure also provides requirements for administration of the AIST Pressure Relief Device Program as discussed in Section 4.2.1 below.
SPP-09.1.25 Procedure eqivalent of OM Code, Appendix II - Check Valve Condition Monitoring Program. This procedure also provides requirements for administration of the AIST Check Valve Condition Monitoring Program as dicussed in Section 4.2.2 below.
These procedures should be used in lieu of direct reference to OM Code where possible because they represent TVAs official position for OM Code meaning and implementation requirements. Thses procedures have been developed to ensure consistent interpretation and implementation of the OM Code requirements at all TVA nuclear plants.
WBN - Unit 0 Augmented Inservice Testing Program 0-TI-100.007 Rev. 0002 Page 23 of 51 4.2 Administration and Implementation of the AIST Program TVA fleet-wide procedures SPP-09.1.20 through SPP-09.1.25 provide specific processes for administration of the AIST Program. This includes day-to-day activities such as:
A.
Evaluation of components which have undergone maintenance and development of new reference values and acceptance criteria (SPP-09.1.21).
B.
Performing periodic trending of component performance (SPP-09.1.22).
C.
Performing periodic review of online and outage schedules for activities which could lead to unacceptable preconditioning (SPP-09.1.23).
Implementation of the WBN AIST Program is accomplished by performance of site specific test procedures developed satisfy the specific component tests identified in Attachment 1 and Attachment 2 of this procedure. These implementing procedures are also listed in the appendices where possible. Scheduling of the implementing test procedures is controlled by procedure NPG-SPP-06.9.2. Exceptions to this implementation method are described below.
The WBN AIST Program is supplemented by two sub-programs: a) AIST Pressure Relief Device Program; b) Check Valve Condition Monitoring Program. This approach was taken because these components in these sub-programs have unique test types and test frequencies based on groups of similar components(e.g., design type, service conditions, performance history, etc) rather than an individual component's categorization. Accordingly,, Augmented Valve Test Plan of this procedure identifies the test type and test frequency for valves included in the sub-programs in general terms such as CM for reference to the Check Valve Condition Monitoring Program and RV for reference to the AIST Pressure Relief Device Program. Additional information regarding each of these sub-programs is provided in Sections 4.2.1 through 4.2.2 below.
WBN - Unit 0 Augmented Inservice Testing Program 0-TI-100.007 Rev. 0002 Page 24 of 51 4.2.1 AIST Pressure Relief Device Program Technical and administrative requirements for the AIST Pressure Relief Device Program are delineated in SPP-09.1.24.
The Pressure Relief Device Program is described in procedures 1/2-SI-0-902, 1/2-SI-0-911, and 0-SI-0-915. These procedures provide a list of the valve groups, valves in each group, and the test frequency for each valve and valve group. As a matter of convenience, the Pressure Relief Device Program includes components in scope of both the IST Program (0-TI-100.006) and Augmented IST Program (0-TI-100.007).
4.2.2 Check Valve Condition Monitoring Program Technical and administrative requirements for the Check Valve Condition Monitoring Program are delineated in SPP-09.1.25.
The Check Valve Condition Monitoring Program is described in procedure 0-TI-100.013.
This procedure provides a list of the valve groups, valves in each group, condition monitoring activites (e.g., tests, examinations) and frequency for each valve group, and reference to the evaluation prepared to substantiate the condition monitoring activities (Condition Monitoriting Plan). As a matter of convenience, the Check Valve Condition Monitoring Progam includes components in scope of both the IST Program (0-TI-100.006) and Augmented IST Program (0-TI-100.007).

Applicable Code Requirement
ISTB-3300 Reference Values (a) Initial reference values shall be determined from the results of testing meeting the requirements of ISTB-3100, Preservice Testing, or from the results of the first inservice test.
Reason for Request
Relief is being requested for establishing vibration reference value (Vr) solely on the basis of the data collected during preservice or inservice testing for those vibration points that have unusually low levels of vibration. This request applies only to values for Vr associated with vibration testing.
Small values for Vr result in small acceptable ranges for pump operation. The acceptable range defined in Table ISTB-5121-1 and Table ISTB-5221-1 is less than or equal to 2.5Vr. Based on a small acceptable range, a smooth running pump could be subject to unnecessary corrective action caused by numerically small changes in vibration levels.
WBN - Unit 0 0-TI-100.007 Augmented Inservice Testing Program Rev 0002 Page 34 of 51 - Augmented Pump Alternative Test Justifications Page 2 of 4 ATJ-P1 Pump Vibration Reference Values and Acceptance Criteria Proposed Alternative and Basis for Use Proposed Alternative Pumps with a measured Vr less than or equal to 0.05 inches per second (ips) for a particular vibration measurement location shall have subsequent test results for that location compared to an acceptable range based on 0.05 ips. In addition to the applicable ASME OM Code requirements, all pumps in the IST Program will be included in and will remain in the Predictive Maintenance Program regardless of their smooth running status.
When new reference values are established, the measured parameters will be evaluated for each location to determine if the provisions of this relief request still apply. If the measured Vr is greater than 0.05 ips, the requirements of ISTB-3300 will be applied even if the pump is identified above. Conversely, if the measured Vr is less than or equal to 0.05 ips, a minimum value of 0.05 ips will be used in determining the acceptable, alert, and required action ranges.
Basis for Use For very small reference values, hydraulic noise and instrument error can be a significant portion of the vibration reading and affect the repeatability of subsequent measurements. Also, experience gathered from the Unit 1 preventive maintenance program has shown that changes in vibration levels in the range of 0.05 ips do not normally indicate significant degradation in pump performance.
To avoid unnecessary corrective action, a minimum Vr of 0.05 ips is being established for velocity measurements.
This minimum value will be applied to individual vibration locations for the pumps listed in the above table where the measured reference value is less than 0.05 ips.
The Predictive Maintenance Program currently employs the following predictive monitoring techniques on an as applicable and as needed basis:
A. Vibration monitoring and analysis beyond that required by ISTB, B. Oil sampling and analysis, and C. Thermographic Analysis.
Bearing temperature trending is available for a number of the components through the plant process computer system.

Applicable Code Requirement
ISTB-5121 Group A Test Procedure Group A tests shall be conducted with the pump operating at a specified reference point.
ISTB-5121(b)
The resistance of the system shall be varied until the flow rate equals the reference point.
Reason for Request
Relief is being requested from establishing specific reference points before obtaining pump test data. Due to normal variations in system flow (even at steady state conditions), it is not possible to set the flow rate for the pump test at a specific value. The OM Code does not provide a tolerance for setting the reference point. NUREG-1482 allows the use of a 2% tolerance (including instrument accuracy) for setting the reference point, however, the ultrasonic M&TE used to set the reference point flow rate is 2% accurate leaving no tolerance for setting the flow rate reference point.
WBN - Unit 0 0-TI-100.007 Augmented Inservice Testing Program Rev 0002 Page 36 of 51 - Augmented Pump Alternative Test Justifications Page 4 of 4 ATJ-P2 Pump Fixed Reference Value Setting Tolerance Proposed Alternative and Basis for Use Proposed Alternative A total reference point setting tolerance will be established of +/- 5 gpm. Including the M&TE accuracy of 2%, this will result in a reference point setting inaccuracy of 2.72%. To offset the additional 0.72% setting inaccuracy, the acceptance criteria applied to the Alert and Required Action ranges will be adjusted (reduced).
Basis for Use NUREG-1482 states that a 2% reference point setting tolerance (including M&TE accuracy) is allowed without obtaining NRC approval. If the total inaccuracy exceeds this 2% tolerance, then the excess variance must be justified and acceptance criteria adjusted as necessary.
There is no design requirement for pump total head. There is only a requirement for flow rate (350 gpm for the Main Control Room CW pumps, 450 gpm for the Electric Board Room and Shutdown Board Room CW pumps). The fixed reference points for these pumps are set at values sufficiently above the minimum required design flow rates to allow for the 2.72% tolerance of the reference point setting. This ensures that the pumps meet the design requirement for minimum flow rate during each test. The acceptance criteria applied to pump total head is adjusted to account for the reference point setting inaccuracy.

WBN - Unit 0 0-TI-100.007 Augmented Inservice Testing Program Rev 0002 Page 38 of 51 - Augmented Valve Alternative Test Justifications Page 2 of 7 ATJ-V1 Ventilation System Refrigerant Relief Valves These valves are in the scope of the Augmented Inservice Testing program. They are located on a non-code class (TVA Class M) section of piping as depicted in drawing 0-47W865-3 and -7, 1-47W865-6, and 2-47W865-6. According to System Description, N3-30CB-4002, Control Building Heating, Ventilating, Air Conditioning, And Air Cleanup System Unit 1/Unit 2, the Main Control Room (MCR) Air Conditioning Subsystem provides a safety function to maintain a controlled environment for the operators and for the equipment in the Main Control Room Habitability Zone (MCRHZ) and the Electrical Board Room (EBR)
Subsystem provides a safety function to maintain a controlled environment for equipment in areas such as the Battery & Battery Board Rooms, Secondary Alarm Station, Plant Computer Room, Auxiliary Instrument Rooms, and Mechanical Equipment Room. The valves perform a safety function to open to provide overpressure protection for the refrigeration/ventilation loops in these subsystems and to remain closed to maintain the refrigerant pressure boundary.
Per Condition Report (CR) 1568606, the Nuclear Safety function of the relief valves is to remain closed to maintain the refrigerant pressure boundary, preventing loss of refrigerant that may cause the chiller / ACU to become inoperable / nonfunctional. The subject valves are refrigerant relief valves that have a safety function for system pressure control to prevent over pressurization of refrigerant containing vessels. These relief valves are pressure safety valves and open based only on over pressure, the valves do not perform a thermal relief function. The relief valve expels refrigerant to the outside atmosphere via a piping system to ensure any relief of the refrigerant is not released to the immediate atmosphere for personnel safety. It is assumed that once the relief valve pops the chiller or Air Conditioning Unit (ACU) has malfunctioned or may not continue to function as required due to the loss of refrigerant. In addition, once the relief valve has popped it cannot be guaranteed to reseat or maintain the pressure setpoint, which would again cause the chiller or ACU to be considered inoperable. The associated refrigerant piping is TVA Class M (class I(L)) and would be required to perform its design function of pressure relief during and following an accident condition in which the chiller / ACU is required to function.
The valves provide over-pressure protection for ventilation subsystems listed in WBN Tech Specs 3.7.11, Technical Requirement Manual 3.7.5, and FSAR 9.4.1.

Ambient temperature and test media temperature shall be established and valve thermal equilibrium confirmed before starting set-pressure testing. The valve shall be considered at thermal equilibrium only when the valve body temperature has stabilized and does not change more than 10°F (5.5°C) in 30 min as measured directly or determined by correlation from other valve temperature measurements. Valves insulated in service shall be insulated in a like manner during testing. Verification of thermal equilibrium is not required for valves that are tested at ambient temperature using a test medium at ambient temperature.
(e) Ambient Temperature. The ambient temperature of the operating environment shall be simulated during the set-pressure test. If the effect of ambient temperature on set-pressure can be established for a particular valve type, then the valve may be set-pressure tested using an ambient temperature different from the operating ambient temperature. Correlations between the operating and testing ambient temperatures shall comply with the requirements of I-8320 and I-8330.
(f) Superimposed Back Pressure (1) Consideration of variable or constant back pressure in set-pressure setting is not required for balanced pressure relief valves, if the back pressure does not exceed 50% of the valve set-pressure.
However, the set-pressure shall consider the effects of bonnet pressure when the bonnet vent is piped to a pressure or vacuum discharge other than atmospheric.
(2) Constant superimposed back pressure in set-pressure setting shall be considered for nonbalanced pressure relief valves when the back pressure exceeds 1% of the set-pressure. For conventional nonbalanced valves with constant superimposed back pressure, the required set-pressure shall be calculated by subtracting the superimposed back pressure from the stamped set-pressure.
(g) Control Rings. Adjustment of control rings to ensure valve action is permitted. For set-pressure acceptance testing, control ring positions shall not be altered between successive openings. Adjusted control rings shall be returned to their proper operating position prior to return to service, as documented by the Owner.
(h) Time Between Valve Openings. A minimum of 5 min shall elapse between successive openings.

I-8200 Seat Tightness Testing Seat tightness testing shall be performed in accordance with the Owner's valve test procedure.
Consideration shall be given to test media, temperature stability, and ambient temperature, as required in I-8100. Seat tightness testing shall be performed using the same fluid used for set-pressure testing, except as provided by I-8300.

The inlet pressure for seat leak testing shall be in accordance with one of the following:
(a) maximum system operating pressure (b) 90% of spring setting or 5 psig (34 kPa) below spring setting for valves having a spring set-pressure less than 50 psig (344 kPa)

Either the original valve equipment design specification acceptance criteria or acceptance criteria established by the Owner in the valve test procedure shall be used for valve seat leakage acceptance criteria.
(10CFR-50.55a(f)(4) dated July 18, 2017, expands the ASME OM Code scope through a modification to include components outside Class,1 2, and 3 boundary and further states that an AIST program may be acceptable.
Reason for Request
As stated by multiple relief valve vendors, these valves do not reliably reseat following set-pressure testing.
Therefore, a variance is being made regarding the requirement to meet ASME OM Code requirements related to all aspects of testing (frequency, instrumentation, periodic testing, fluids and correlation of alternative, number of required set-pressure tests, and seat tightness) of refrigerant relief valves which are included in the AIST program.
Burden Caused by Compliance These valves are not ASME Section III valves and are typically built and tested per ASME Section VIII.
The inability to adequately test the refrigerant relief valves causes needless work on attempting to rebuild these valves. Vendor drawings for the currently installed Henry valves and the authorized replacement vendor valves (Mueller) each discuss that these valves are considered to not require any field adjustment and are intended for one time over-pressure operation and must be replaced immediately after discharging because the setting or seat tightness may be altered. Discussions with the Mueller valve vendor revealed that in addition to the single use valve discussed above, these valves are typically tested in error when parties other than the vendor attempt testing which is attributed to the oil in the refrigerant vs. attempting to set-pressure test with Nitrogen. Additionally, WBN does not have a correlation for using Nitrogen in lieu of the refrigerant.
WBN - Unit 0 0-TI-100.007 Augmented Inservice Testing Program Rev 0002 Page 43 of 51 - Augmented Valve Alternative Test Justifications Page 7 of 7 ATJ-V1 Ventilation System Refrigerant Relief Valves Another point to note is a recent design change package is to replace a portion of these valves along with their associated chillers in the near future. The new replacement valves manufactured by Hansen Technologies are also considered to be single use valves.
Discussions with WBN Design Engineering reveal that the analysis of the Main Control Room and Shutdown Board Room chillers assumes that upon one of the relief valves exceeding the setpoint pressure, all refrigerant is expelled during the valve lift rendering the chiller inoperable.
Based on the issues identified by all three relief valve manufacturers for this application, the valves purchased/installed, and the inability to adequately test these valves on-site, it is considered a burden to attempt repeated testing and repair of these valves.
Proposed Alternative and Basis for Use Proposed Alternative These valves will be treated as untestable thermal relief valves and will accept the vendor test provided with new valves when procured. No periodic testing on these valves will be performed. Each valve will be replaced every five years in lieu of the normal frequency of ten years specified in I-1390.
Basis for Use The ASME OM Code requirements for set-pressure testing these valves periodically cannot be performed due to the vendor and Site Engineering considerations that once popped, the valve may or may not reseat and the repeatability of the set-pressure test cannot be assured once lifted. Additionally, Site Engineering assumes that once the relief valve lifts, the refrigerant from the associated chiller is expelled and the chiller is inoperable.
In conclusion, periodic replacement of the valves will provide an equivalent method for complying with ASME OM Code requirements without a reduction in safety or quality.
Duration of the Proposed Alternative This request is for the duration of the Combined Unit 1 Third and Unit 2 First IST ten-year Interval (began October 19, 2016 and ends October 18, 2026).

Deferred Test Frequency:
Full stroke exercise with stroke time closed (STC) on a Refueling Outage (RO) frequency.
Fail Safe Close (FSC) on a Refueling Outage (RO) frequency.
Justification for Deferred Test Frequency:
Exercising these valves during power operation causes a change of feedwater flow to the Steam Generator they supply which in turn causes a steam generator level transient, either of which could result in unit trip and safety injection. Stroke time testing of the FCVs is normally performed in mode 3 during shutdown for a refueling when isolation of feedwater is performed. The test procedure is written to allow performance during modes 5 and/or 6, but performance in these modes requires extensive lifting/re-landing of permanent wiring and installation/removal of jumpers and test switches to allow testing of individual valves. Modes 5 and 6 performance is only used for Post Maintenance Testing purposes on a valve-by-valve bases. Therefore, testing during forced outages is NOT practical.
