WATTS BAR WBNP-105 THIS PAGE INTENTIONALLY BLANK 14.1-2 SPECIFIC INFORMATION TO BE INCLUDED IN PRELIMINARY SAFETY ANALYSIS REPORT
WATTS BAR WBNP-105 14.2 TEST PROGRAM 14.2.1 Summary of Test Program and Objectives The purpose of the initial test program for the Watts Bar Nuclear Plant (WBNP) is to assure that the installed plant structures, systems, and components will be subjected to tests as required to verify that the plant has been properly designed and constructed and is ready to operate in a manner that will not endanger the health and safety of the public, and to provide assurance of total plant reliability for operation. The test program will also ensure, to the extent practical, that the procedures for operating the plant safely have been evaluated and demonstrated and that the operating organization is knowledgeable about the plant and procedures.
The necessary procedures to control, implement, and document the test program are established by startup and plant administrative procedures and summarized in the following sections. Tennessee Valley Authority (TVA), as the applicant, has responsibility for overall direction and management of the test program.
The initial test program is divided into two phases, the preoperational test phase and the power ascension test phase. Preoperational phase testing will be performed prior to fuel load and power ascension testing will be performed during and following fuel loading activities. During each of these two phases, tests will be performed to verify design requirements of safety-related and selected non-safety-related components, systems, and structures. A graded approach, based on criteria provided in Regulatory Guide 1.68, Revision 2, will be used for selection of plant structures, systems, components, and design features to be included in the initial test program. During the preoperational testing phase, three types of tests will be performed: (1) component tests, (2) preoperational tests, and (3) acceptance tests.
Component (preliminary) tests will be performed on safety-related and non-safety-related components and consist of items such as instrument calibration, flushing, cleaning, and functional tests of individual components to demonstrate conformance with design requirements. Component testing will prepare individual components for system level testing. Verification that appropriate component testing is complete is prerequisite to performance of preoperational (system level) tests as described in Section 14.2.12.1.
Preoperational test instructions will be performed on safety-related and selected non-safety-related structures, systems, components, and design features as required to demonstrate their capability to perform in accordance with design requirements.
Preoperational tests are intended to demonstrate the proper operation of system design features through integrated operation of components under normal and transient conditions, where practical, including system and component interactions.
Such tests also demonstrate the capability of certain component design features for which system operation is required to establish the necessary test conditions.
Summaries of preoperational test instructions are provided in Table 14.2-1.
TEST PROGRAM 14.2-1
WATTS BAR WBNP-105 Acceptance test instructions will be performed on components and systems which do not perform a safety-related function and are not required for safe shutdown and cooldown of the reactor under normal or upset conditions as described in the applicable sections of the FSAR. Acceptance tests are not summarized in Table 14.2-1.
Components and systems which are not tested in accordance with a preoperational or acceptance test instruction will be tested and/or placed into service in accordance with procedures which are appropriate for the installation.
During the power ascension testing phase, power ascension tests, surveillance instructions, and other permanent plant tests and technical instructions will be performed to demonstrate satisfactory operation of systems. Summaries of power ascension testing to be performed during the initial test program are provided in Table 14.2-2.
Regulatory guidance will be used for development of initial test program requirements as discussed in Section 14.2.7.
Tests summarized in Table 14.2-1 will be completed and test results approved prior to commencing fuel load. Tests, or portions thereof, which can not be completed prior to fuel load will be evaluated to assure incomplete tests will not adversely affect fuel loading operations or cause features that have not been tested to be relied upon for safe plant operation. The Joint Test Group (JTG) and the Plant Operations Review Committee (PORC) or the Test Review Group (TRG) will review the technical justification for delaying test completion until after fuel load. If approved by the Plant Manager, the technical justification and schedule, including power level for completion of delayed testing, will be provided to the NRC staff prior to fuel load.
Power ascension tests will be performed beginning with activities leading to fuel loading and ending with full power operation. The intent of these tests is to assure that fuel loading is effected in a safe manner; that tests deferred from the preoperational test phase are completed satisfactorily; that the plant is safely brought to rated capacity; that plant performance is satisfactory in terms of established design criteria; and to demonstrate, where practical, that the plant is capable of withstanding anticipated transients and postulated accidents. Testing activities related to fuel load and initial criticality are further described in Section 14.2.10.
Tests will be conducted in accordance with approved test procedures. Review, approval, and revision of test procedures and the evaluation and disposition of test results will be accomplished by methods specified in the appropriate administrative procedures summarized in Section 14.2.3. Preoperational and power ascension tests are discussed in Section 14.2.12.
The initial test program will utilize, to the extent practical, operations personnel and operating procedures to provide familiarization with the plant installation and demonstrate the adequacy of operating procedures.

14.2.7 Conformance of Test Programs with Regulatory Guides The initial test program will be developed and conducted in accordance with the following applicable NRC Regulatory Guides (RG). In certain cases, exceptions or alternate approaches to regulatory guidance are planned. Justification for these exceptions or alternate approaches are provided with the applicable regulatory guide.
(1) RG 1.20, "Comprehensive Vibration Assessment Program for Reactor Internals During Preoperational and Initial Startup Testing," Revision 2 Discussion:WBN reactor internals are not a prototype design. Exception is taken to certain requirements of RG 1.20. Refer to FSAR Sections 3.9.2.3, 3.9.2.4, 3.9.2.5, and 3.9.2.6 for justification of exceptions and alternate plans.
(2) RG 1.41, "Preoperational Testing of Redundant On-site Electric Power Systems to Verify Proper Load Group Assignments," Revision 0 Discussion:The initial test program will comply fully with the requirements of RG 1.41 as discussed in FSAR Section 8.1.5.3.
(3) RG 1.52,"Design, Testing, and Maintenance Criteria for Atmospheric Cleanup System Air Filtration and Absorption Units of Light-Water-Cooled Nuclear Power Plants," Revision 2 Discussion:See Tables 6.5-1, 6.5-2, 6.5-3, and 6.5-4 for discussion of compliance with RG 1.52 and associated ANSI standards.
(4) RG 1.68,"Initial Test Programs for Water-Cooled Nuclear Power Plants" Discussion:The initial test program complies with the requirements of RG 1.68, Revision 2 (8/78), with the following exceptions and/or alternate approaches:
TEST PROGRAM 14.2-15
WATTS BAR WBNP-105 (A) Regulatory Position C.1 (1) WBN takes specific exception to some provisions of RG 1.68. These include:
(a) Appendix A, subparagraph 1.c Acceptance criteria for the response time of the various logic channels will be consistent with Technical Specifications requirements. The Reactor Trip System Response Time is defined in the Technical Specifications as the time interval from when the monitored parameter exceeds its trip setpoint at the channel sensor until loss of stationary gripper coil voltage. The accident analysis accounts for conservative values for delay times, setpoint drift, etc. Therefore, it is not necessary to account for the response time of the associated hardware between the measured variable and the input to the sensor in the test or acceptance criteria.
(b) Appendix A, subparagraph 1.g.2 Emergency loads will not be tested with minimum and maximum design voltage available. Emergency loads will be tested to demonstrate satisfactory starting and operating characteristics with power supply voltage within the design operating range.
Transformer taps will be adjusted to obtain optimum voltage levels from no-load to full load conditions. Tests will be performed to record operating parameters of the offsite grid, Class 1E 6.9 kV, 480 volt, and 120 volt vital power busses under no-load, steady state load, and transient conditions. Data will be obtained for the Class 1E train having the lowest analyzed voltage. The recorded information will be compared to engineering voltage calculations to validate the analytical models used.
(c,1) Appendix A, subparagraph 1.h.3 Testing of non-safety related portions of the ice condenser system will be accomplished by component tests in accordance with Reference 11. Air return fans are tested under Containment Ventilation preoperational tests.
14.2-16 TEST PROGRAM
WATTS BAR WBNP-105 (c,2) Appendix A, subparagraph 1.j.10 Seismic instrumentation was tested and is operational to support Unit 1.
(d) Appendix A, subparagraph 1.j.12, and 5q The gross failed fuel detection system (GFFDS) is abandoned in place. Periodic sampling is used to detect failed fuel as described in Section 9.3.2.2 10 CFR 50, Appendix A and RG 1.97 do not require a GFFDS and, from a practical standpoint, there is no justification for the monitor. This particular design detects delayed neutrons and any type of failure that would be detected by this monitor would be putting significant fuel particles into the coolant.
To damage fuel to this extent would require either a severe transient, foreign material damage or an unusual design problem, such as baffle jet impingement. The plant is designed to operate such that clad damage will not occur. Technical Specifications limits on pressure, temperature, flow and power ensure that cladding is not damaged during normal operations, including anticipated transients. Reactor coolant is sampled frequently.
Although Technical Specifications only require gross specific activity and dose equivalent I-131 analyses every 7 days and 14 days during power operations, coolant will actually be sampled for other parameters at least every 72 hours8.333333e-4 days <br />0.02 hours <br />1.190476e-4 weeks <br />2.7396e-5 months <br />. The radcon surveys required to handle these samples would detect any significant activity changes. If power changes 15% or more in any one hour, a special sample is required between 2 and 6 hours6.944444e-5 days <br />0.00167 hours <br />9.920635e-6 weeks <br />2.283e-6 months <br /> after the power change.
Due to the ability to monitor the conditions that damage fuel cladding, it is easily determined if sampling should be performed for evidence of damage. Monitors for subcooling margin, incore thermocouples, and reactor vessel level are examples of monitors that would indicate clad damaging conditions.
Foreign material damage (monitored by noise monitor) and baffle jet impingement have resulted in non-catastrophic clad failures at other plants which were detected and monitored by normal chemistry sampling.
(e) Appendix A, subparagraphs 1.k.2, and 1.k.3 The subject equipment is calibrated and functionally tested as part of the WBN plant instrument calibration program. The calibration and functional testing is performed and documented in TEST PROGRAM 14.2-17
WATTS BAR WBNP-105 accordance with approved plant calibration procedures.
Therefore, additional testing in the form of a preoperational test is not warranted.
(f) Appendix A, subparagraph 1.k.4 Refer to 14.2.7.3 for discussion of compliance with requirements for filter and in-place leak tests.
(f,1) Appendix A, subparagraph 1.l.3 Testing of the non-safety related solid waste processing system was accomplished during Unit 1 initial testing.
(g) Appendix A, subparagraph 1.m.1 Only the Unit 2 refueling water purification subsystem will be tested during the preoperational phase. Because of its non-safety related nature, the testing will be accomplished by a combination of system and/or component level testing in accordance with Reference 11.
(h) Appendix A, subparagraph 1.m.4 Static load testing at 125% of rated load for equipment and components used to handle irradiated or non-irradiated fuel originates from an ANSI B30.2-1976 (now ASME B30.2-1990) rated load test requirement. This test is purposed to verify the structural integrity of the handling equipment and is utilized to rate its capacity. Handling equipment is rated at 80% of the test load, resulting in a rating of 100% capacity when test loads are 125%.
This ANSI testing is required to be performed prior to initial use, and following extensive repairs or modifications. Both hooks of the polar crane have been successfully load tested at 125% rated capacity in prior tests. Additionally, this equipment has had no extensive maintenance or modifications which would affect structural integrity. Therefore, repeated load testing of this equipment is not warranted. Common equipment previously used 14.2-18 TEST PROGRAM
WATTS BAR WBNP-105 for handling Unit 1 fuel was load tested before initial use and will not be addressed.
Operational testing of cranes not associated with spent fuel movement was accomplished in accordance with Reference 14.
(h,1) Appendix A, subparagraph 1.n.13 Testing of the non-safety related communications system will be accomplished in accordance with reference 11.
(h,2) Appendix A, subparagraph 1.n.14 Testing of the intake pump station ventilation system was accomplished during Unit 1 initial testing.
(i) Appendix A, subparagraph 1.n.18 Because of its non-safety related, and simple functions, trace heating systems will receive component level tests, not preoperational or acceptance testing.
(j) Appendix A, subparagraphs 2.b.
Cold, no-flow, cold, full-flow and hot, no-flow rod drops do not provide any additional useful data. The drop times for these flow conditions are less conservative than for hot, full-flow conditions.
WBN does not intend to perform cold, no-flow, cold, full- flow and hot, no-flow rod drops.
(k) Appendix A, subparagraphs 2.f and 5.m WBN does not intend to perform a differential pressure measurement across the core nor a core flow measurement since these are prototype tests. WBN is not a prototype model plant, but, instead, is a well documented production model with several similar predecessor reactor units (Indian Point Unit 2, Trojan, and Sequoyah Unit 1) of its type. Proper differential pressures across the core and core flow is shown indirectly through performance of other tests that verify operating temperature and RCS flow.
(l) Appendix A, subparagraphs 4.c and 5.e No new design information is to be gained from the RCCA Pseudo Ejection Test. WBN is not a prototype plant for 4 loop, 12 foot core with 17 x 17 fuel design. Performance and measurement data TEST PROGRAM 14.2-19
WATTS BAR WBNP-105 already exists for this design. Therefore, WBN will not perform this test.
(m) Appendix A, subparagraphs 4.g and 5.z The proper response of process and effluent radiation monitors is demonstrated under the plant calibration program and during preoperational testing for the Process and Effluent Radiation Monitoring System (Sheet 31, Table 14.2-1). It is not expected that enough leakage in fuel cladding, steam generator tubes or heat exchangers will exist to provide a meaningful comparison between radiation monitor responses and laboratory analysis of samples.
Therefore, WBN will not perform special power ascension testing of process and effluent radiation monitors.
(n) Appendix A, subparagraph 4.t Natural circulation tests of the Reactor Coolant System will not be performed. Such tests have been successfully completed at Diablo Canyon Unit 1, McGuire Unit 1, Salem 2, Sequoyah 1 and other Westinghouse plants similar to WBN. It is unnecessary for WBN to compare flow (without pumps) and temperature data to data at these plants since no design differences exist which would significantly effect natural circulation capabilities. Typical natural circulation characteristics for 4 loop Westinghouse plants are given in WCAP-8460, "Natural Circulation Test Report for Zion Station Unit 1." However, in order to verify natural circulation cooldown and boron mixing capability per requirements of Branch Technical Position RSB 5-1, WBN has referenced test results (Refer to WCAP-12334) from Diablo Canyon Unit 1, and the WBN design is comparable to Diablo Canyon Unit 1.
(o) Appendix A, subparagraph 5.a Power reactivity coefficients will not be determined at 25%, 50%,
75%, and 100% power levels. The power coefficient is not directly measured but is inferred. The required measurement for the test is time consuming compared with the value of the data obtained.
The measurement has been previously deleted at other plants based on inferred measurements at similar plants. WBN is similar to Sequoyah Units 1 & 2 and McGuire Units 1 & 2. The Doppler power coefficient was inferred and compared with design values in three of these four units. The comparison between the inferred measurements and design values was within acceptance criteria in all cases thus demonstrating the ability to analytically predict this design parameter. However, overall core reactivity will be measured during low power physics testing and at approximately 14.2-20 TEST PROGRAM
WATTS BAR WBNP-105 100% power which demonstrates the adequacy of core design reactivity coefficients.
(p) Appendix A, subparagraph 5.d WBN plant design does not include part-length control rods. The ability to control core xenon transients is a design feature of the Westinghouse Nuclear Steam Supply System and has been demonstrated in numerous operating pressurized water reactors.
In addition, compliance with Technical Specifications for Axial Flux Difference helps ensure proper power and flux distributions.
On these bases, WBN does not intend to perform an Initial Power Ascension Test to comply with subparagraph 5.d.
(q) Appendix A, subparagraph 5.f WBN does not intend to perform a pseudo dropped rod test.
There is no appreciable new data that would be obtained from performing this test. Previous plants have proved the design bases for typical cores.
(r) Appendix A, subparagraph 5.i The Power Distribution Monitoring System is not designed to verify the position of all RCCA's that might be misaligned from their bank.
(s) Appendix A, subparagraph 5.u Operability and response times of the main steam isolation valves will be verified in hot standby (mode 3) rather than at the recommended 25% power level. Testing at hot, zero power will result in more conservative results and will eliminate the unnecessary pressure and steam flow transients which would otherwise be induced.
(t) Appendix A, subparagraph 5.i.i The performance of this test provides no new information needed to verify the plant performance during design transients. A trip of the reactor coolant pumps results in a reactor trip with flow coastdown, as verified in the Reactor Coolant System Flow Coastdown Test, providing sufficient heat removal to ensure DNBR does not decrease below WBN's limiting design value.
TEST PROGRAM 14.2-21
WATTS BAR WBNP-105 Performing this test expends one of the analyzed transients and results in unnecessary cost and down time for the utility.
(u) Appendix A, subparagraph 5.k.k The most influential contributor for this transient is the value of moderator temperature coefficient of reactivity, which has a relatively low value at beginning of core life. Since this parameter is determined in other startup tests, thus validating the safety analysis, the performance of this test provides no new information needed to verify the plant design. The transient does introduce the potential for thermal stress damage to the steam generator feedwater inlet nozzles and it expends one of the analyzed thermal cycles. Therefore, we do not intend to perform a test to comply with this subparagraph.
(v) Appendix A, subparagraph 5.m.m The performance of this test provides no new information needed to verify the plant performance during design transients. Closure of all main steam isolation valves from 100% power will result in a turbine trip and a reactor trip. Turbine trip and reactor trip from 100% power will be performed during initial power ascension testing.
Closure of the MSIV's may cause operation of the pressurizer and steam generator power operated relief valves and/or safety valves which may then require repair and unnecessary down time for the utility. This test would expend one of the analyzed pressure transients for the reactor coolant system and steam generators and therefore will not be performed.
(2) Some provisions of RG 1.68 (power ascension phase) do not apply to the design of WBN. These include Appendix A, subparagraphs 4.m, 5.c, 5.d, 5.h, 5.j, 5.q, 5.w, and 5.i.i. In addition, certain portions of some provisions of RG 1.68 (power ascension phase) do not apply to the design of WBN. These include:
(a) Appendix A, subparagraph 2 Shutdown margin verifications should be performed at appropriate loading intervals (BWR) including full core shutdown margin tests. It should be established that the required shutdown margin exists, without achieving criticality.
(b) Appendix A, subparagraph 2.a Shutdown margin verification for partially (BWR) loaded core.
(c) Appendix A, subparagraph 2.b 14.2-22 TEST PROGRAM
WATTS BAR WBNP-105 Friction tests of control rods after the core is fully loaded for BWRs. For facilities using more than one type of control element or control rod drive design, scram times should be compared with identical designs (e.g.,
two control rods attached to a single drive mechanism.)
(d) Appendix A, subparagraph 4.h The design of WBN does not provide for automatic RCS chemical control and analysis. Chemistry specifications are established and monitored as prerequisites for testing as necessary.
(e) Appendix A, subparagraph 5 Testing with single loop reactor coolant system operation.
(f) Appendix A, subparagraph 5.a Power vs. flow characteristics (BWR) are in accordance with design values.

(1) RG 1.68.2, "Initial Startup Test Program to Demonstrate Remote Shutdown Capability for Water Cooled Nuclear Power Plants" Discussion:The testing activities conducted as a part of the Initial Test Program will comply with the applicable requirements of RG 1.68.2, Revision 1 (7/78).
(6) RG 1.79,"Preoperational Testing of Emergency Core Cooling Systems for Pressurized Water Reactors" Discussion:Preoperational testing of the Emergency Core Cooling Systems will comply fully with RG 1.79, Revision 1, (9/75) with exception to Regulatory Position C.1.b(2)
Recirculation Test - Cold Conditions. A satisfactory in-plant test of the containment sump to demonstrate vortex control and acceptable pressure drops across screening and suction lines and valves is not practical. Justification for this exception is provided in FSAR Section 6.3.4.1.
(7) RG 1.68.3,"Preoperational Testing of Instrument and Control Air Systems" Discussion:Preoperational testing of the Instrument and Control Air Systems will comply with RG 1.68.3, April 1982, with the following exceptions:
(a) Regulatory Position C.8 Auxiliary Control Air System loads will be tested on an individual basis to verify their response to a sudden loss of system pressure. NRC concurrence with this exception is reflected in correspondence from R.
C. Lewis to H. G. Parris dated February 28, 1984.
(b) Regulatory Position C.8 TEST PROGRAM 14.2-27
WATTS BAR WBNP-105 Control air system loads (safety related only) will be tested to verify their response to a loss of system pressure. The sudden loss of air pressure will be performed on an individual load basis. Non-safety related air operated loads will be tested on a component basis to verify proper response to a loss of air pressure.
(c) Regulatory Position C.11 Functional testing to demonstrate operability of compressed air system loads under increased pressure conditions will not be performed. The safety evaluation of the system indicates that the system is adequately designed to prevent system overpressure as described in Section 9.3.1.3. The maximum pressure rating of the most limiting component of the system piping, valves, and equipment (up to the end user pressure regulator) was determined to be at least 20 psi higher than the system safety valve setpoint plus 10% accumulation. This ensures that there is adequate protection against overpressurization.
(8) RG 1.95, "Protection of Nuclear Power Plant Control Room Operators Against an Accidental Chlorine Release," Revision 1, January 1977.
Discussion:The potential for chlorine to pose a hazard to main control room (MCR) operators due to onsite storage spills or transportation incidents in the vicinity of the site is analyzed in FSAR Section 6.4.4.2. The analysis concluded that no hazard to control room habitability is posed by chemicals stored on site, offsite within a 5-mile radius, or transported by the site by barge, rail, or road within a 5-mile radius. Therefore, the requirements of RG 1.95, Revision 1, (January 1977) "Protection of Nuclear Power Plant Control Room Operators Against an Accidental Chlorine Release" do not apply.
(9) RG 1.9, "Selection, Design, Qualification and Testing of Emergency Diesel Generator Units Used as Class 1E Onsite Electric Power Systems at Nuclear Power Plants".
Discussion:See RG 1.9 discussion in Section 8.1.5.3.
(10) RG 1.118, "Periodic Testing of the Electric Power and Protection Systems" Discussion:Testing of the Reactor Protection System will be in compliance with the requirements of RG 1.118, Revision 2 (6/78).
(11) RG 1.139, "Guidance for Residual Heat Removal," for comment, May 1978 Discussion:This regulatory guide will not be used for development or conduct of the WBN initial test program.
A final report of a comparison between WBN and Sequoyah was submitted to NRC by Reference [3]. This study addressed requirements of Regulatory Guide 1.139 and Branch Technical Position RSB 5-1. This report indicated 14.2-28 TEST PROGRAM
WATTS BAR WBNP-105 that preoperational test results to demonstrate natural circulation cooldown capability at Diablo Canyon were applicable to the WBN design and satisfy NRC requirements for natural circulation tests. Reference [5] confirmed acceptability of this approach, pending review of Diablo Canyon test results.
More recently, Reference [4] provided an assessment of the applicability of the Diablo Canyon natural circulation test to WBN. This assessment concluded that natural circulation tests are not required at WBN, and was accepted by the NRC in Reference [6]. Further review on this issue is documented in Sections 5.4 and 14 of Reference [7].
Exception has been taken to RG 1.68, Revision 2, requirements for performing natural circulation tests of the reactor coolant system, as described in this section and in Section 14.2.7.4.A(1)(n).
(12) RG 1.140, "Design, Testing, and Maintenance Criteria for Normal Ventilation Exhaust System Air Filtration and Adsorption Units of Light-Water-Cooled Nuclear Power Plants," Revision 1 (10/79)
Discussion:Testing of normal (non-safety related) ventilation exhaust filtration systems will be performed in full compliance with guidance provided by this Regulatory Guide.
14.2.8 Utilization of Reactor Operating and Testing Experience in Development of Test Program The WBN initial test program will utilize information gained from operating and testing experience in other similar nuclear plants. This information will be used to provide guidance in developing test procedures and schedules and to alert personnel to potential problem areas.
TVA has an established Nuclear Experience Review (NER) Program. The NER Program identifies and evaluates experience gained from TVA nuclear plants, Institute of Nuclear Power Operations (INPO), Nuclear Regulatory Commission (NRC), from other nuclear utilities, architect-engineers and contractors, equipment suppliers, and others within the nuclear industry. The program ensures that significant operational experience and events are reviewed and integrated into applicable programs/
procedures to enhance nuclear safety and reliability. Items that could impact testing will be reviewed by the appropriate testing organization to determine appropriate actions such as procedure revisions, review of completed test, retest, etc.
Additionally, testing and operating experience gained from Unit 1 will be incorporated into the Unit 2 test program.
14.2.9 Trial Use of Plant Operating and Emergency Procedures To the extent necessary, the plant operating, emergency, surveillance and periodic test instructions/procedures will be use-tested during the initial test program and will also be used in the development of preoperational and initial power ascension procedures to the extent practical. The trial use of plant instructions serves to TEST PROGRAM 14.2-29
WATTS BAR WBNP-105 familiarize operating personnel with systems and plant operation during the testing phase and also serves to assure the adequacy of the procedures under actual or simulated operating conditions before plant operation begins.
Prior to fuel load, draft operating instructions may be utilized for equipment operation.
The operating instructions will be revised as necessary to reflect experience gained during the actual testing.
During the power ascension test phase, power escalation tests normally performed once each cycle during startup will be performed to demonstrate their adequacy.
14.2.10 Initial Fuel Loading, Postloading Tests, Initial Criticality, Low Power Tests and Power Ascension Fuel load will begin after review and approval of the results of tests summarized in Table 14.2-1. At the completion of fuel load, the reactor upper internals and pressure vessel head will be installed and additional mechanical and electrical tests will be performed to prepare the plant for nuclear operation. All precritical tests will be performed prior to initial criticality and the results evaluated. Then nuclear operation of the reactor will begin. This phase of testing includes initial criticality, low power testing and power level escalation and testing. The purpose of these tests is to verify the operational characteristics of the unit and core, to acquire data for the proper calibration of instruments, and to ensure that operation is within license requirements.
14.2.10.1 Fuel Loading Core loading instructions will specify the condition of certain fluid systems to prevent inadvertent dilution of the reactor coolant; specify the movement of fuel to preclude the possibility of mechanical damage; prescribe the conditions under which loading can proceed; designate responsibility and authority and provide for continuous and complete fuel and core component accountability.
Prior to starting actual fuel load operations, the reactor containment structure will be completed and the containment building penetrations will be in the condition required by Technical Specifications. Fuel-handling tools and equipment will have been checked out and dry runs conducted in the use and operation of equipment.
Inspections of fuel assemblies, associated core components, and the reactor vessel will be satisfactorily completed. The reactor vessel and associated components will be in a state of readiness to receive fuel. The overall process of initial core loading will be directed by a licensed Senior Reactor Operator and in accordance with applicable Technical Specification requirements. Standard procedures for the control of personnel will be established prior to fuel load.
The as-loaded core configuration is specified as part of the core design studies conducted well in advance of unit startup and as such is not subject to change at fuel load. In the event mechanical damage is sustained during core loading operations to a fuel assembly of a type for which no spare is available on site, an alternate core loading scheme whose characteristics closely approximate those of the initially prescribed pattern will be determined by Westinghouse and TVA.
14.2-30 TEST PROGRAM
WATTS BAR WBNP-105 The fuel assemblies with inserted core components will be inserted into the reactor vessel and submerged in reactor grade water containing adequate dissolved boric acid to maintain a calculated core effective multiplication factor of 0.95 or lower. Core moderator chemistry conditions (particularly boron concentration) will be prescribed and will be verified periodically by chemical analysis of moderator samples taken prior to and during core loading operations.
Core loading instrumentation consists of the installed, calibrated source range nuclear channels. The installed source range channels will be operable per Technical Specifications for monitoring by operations personnel in the control room. At least one of the two channels in the control room will be equipped to provide an audible count rate. Both channels in the control room will have the capability of displaying the neutron flux level on a MCR instruments.
Following the installation of the initial nucleus of 8 fuel assemblies, in front of each source range detector, two channels will be monitoring subcritical multiplication. At least 2 artificial neutron sources located in fuel assemblies will be introduced into the vessel at specified points to ensure detector response. A response check of nuclear instruments shall be performed within 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br /> prior to loading of the core, or resumption of loading, if delay is for more than 8 hours9.259259e-5 days <br />0.00222 hours <br />1.322751e-5 weeks <br />3.044e-6 months <br />. The response check may be performed by using the source fuel assembly as the source prior to being unlatched or by using a portable neutron source. Alternatively, a statistical analysis of the detectors maybe made as a means of response checking the responding detectors.
Fuel assemblies, together with inserted core components, will be placed in the reactor vessel one at a time according to an approved sequence. Plant instructions include detailed tabular check-sheets which prescribe and verify the movements of each fuel assembly and its core component from its initial position in the storage racks to its final position in the core. Checks are made of the fuel assembly ID number to guard against possible inadvertent substitutions of fuel assemblies. A display will be provided for indicating the status of the core throughout the core loading operation.
An initial nucleus of eight fuel assemblies (with inserted core components), one of which contains a neutron source, is the minimum source-fuel nucleus which permits subsequent meaningful inverse count rate monitoring. Calculations indicate that this initial nucleus is markedly subcritical (Keff < 0.95) under the required conditions of loading. Each subsequent fuel assembly addition is accompanied by detailed neutron count rate monitoring to determine that the just loaded fuel assembly does not excessively increase the count rate. The results of each fuel assembly loading will be evaluated before the next prescribed fuel assembly is loaded in the reactor vessel.
Criteria for safe loading require that loading operations stop immediately if:
(1) An unanticipated increase in the neutron count rate by a factor of 2 occurs on all responding nuclear channels during any single loading step after the initial nucleus of 8 fuel assemblies is loaded (excluding anticipated change due to detector and/or source movement).
TEST PROGRAM 14.2-31
WATTS BAR WBNP-105 (2) The neutron count rate on any individual nuclear channel increases by a factor of 5 during any single loading step after the initial nucleus of 8 fuel assemblies is loaded (excluding anticipated change due to detector and/or source movement or detector-to-core coupling).
(3) A decrease in boron concentration greater than 20 ppm is determined from two successive samples of reactor coolant until the decrease is explained.
Alarms in the containment and main control room are coupled to either of the two source range channels with a setpoint equal to or less than five times the current count rate. This alarm automatically alerts the loading operation personnel of high count rate and requires an immediate stop of all operations until the situation is evaluated. Normally, the alarm used for this purpose is the containment evacuation alarm. In the event that the evacuation alarm is actuated, core loading personnel will be evacuated. The situation will be evaluated before core loading is continued. After it has been determined that no hazards to personnel exist, personnel will be permitted to reenter the containment.
14.2.10.2 Postloading Tests Upon completion of core loading, the reactor upper internals and the pressure vessel head will be installed. A test is conducted after filling and venting are completed to check the integrity of the vessel head installation.
Mechanical and electrical tests will be performed on the control rod drive mechanisms.
These tests will include a complete operational checkout of the mechanisms and calibration of the individual rod position indication.
Tests will be performed on the reactor trip circuits to test manual trip operation. The actual control rod assembly drop times will be measured for each control rod assembly.
At all times that the control rod drive mechanisms are being tested, the boron concentration in the moderator will be maintained such that the shutdown margin requirements specified in the Technical Specifications are met. During individual RCCA or RCC bank motion, source range instrumentation is monitored for unexpected changes in core reactivity.
A functional electrical and mechanical check will be made of the Power Distribution Monitoring System. After evaluation of precritical tests, nuclear operation of the reactor will begin.
14.2.10.3 Initial Criticality Initial criticality will be achieved by a combination of shutdown and control bank withdrawal and reactor coolant system boron concentration reduction.
Initially, all shutdown and control banks will be withdrawn incrementally in the normal withdrawal sequence, leaving the last withdrawn control bank inserted far enough in the core to provide effective control when criticality is achieved. The boron 14.2-32 TEST PROGRAM
WATTS BAR WBNP-105 concentration in the reactor coolant system will then be reduced by the addition of primary water.
Inverse count rate ratio monitoring, using data from the source range instrumentation, will be used as an indication of the proximity and rate of approach to criticality. Inverse count rate ratio data will be plotted during control bank withdrawal and subsequent reactor coolant system boron concentration reduction.
Criticality will be achieved during boron dilution, or by rod withdrawal following boron dilution. The rate of primary water addition, and hence, the rate of approach to criticality will be reduced as the reactor approaches criticality to ensure that effective control is maintained. Throughout this period, samples of the primary coolant are obtained and analyzed for boron concentration.
Written procedures specify the plant conditions, precautions and specific instructions for the approach to criticality.
14.2.10.4 Low Power Tests Following initial criticality, a program of reactor physics measurements will be undertaken to verify that the basic static and kinetic characteristics of the core are as expected and that the values of the kinetic coefficients in the accident analysis are conservative.
Procedures will specify the sequence of tests and measurements to be conducted and the conditions under which each is to be performed in order to ensure both safety of operation and the validity and consistency of the results obtained. If test results deviate significantly from design predictions, if unacceptable behavior is revealed, or if unexplained anomalies develop, the unit will be brought to a safe stable condition and the situation reviewed to determine the course of subsequent unit operation.
These measurements will be made at low power and primarily at or near normal operating temperature and pressure. Measurements will be made in order to verify the calculated values of rod bank reactivity worths, the isothermal temperature coefficient, differential boron concentration reactivity worth, and critical boron concentrations.
14.2.10.5 Power Ascension After the operating characteristics of the reactor have been verified by low power testing, a program of power level escalation will bring the unit to its full rated power level in successive stages. Power range nuclear instrumentation high flux trips will be set less than or equal to 20% of RTP above each power plateau before escalating to the plateau. The minimum test requirements for each successive plateau of power escalation will be specified in the power ascension test procedures.
Measurements will be made to determine the relative power distribution in the core as functions of power level and rod bank position.
Secondary system heat balance measurements will ensure that the indications of power level are consistent and provide bases for calibration of the power range nuclear TEST PROGRAM 14.2-33
WATTS BAR WBNP-105 channels. The ability of the reactor coolant system to respond effectively to signals from primary and secondary instrumentation under a variety of conditions encountered in normal operations will be verified.
At prescribed power levels the dynamic response characteristics of the primary and secondary systems will be evaluated. System response characteristics will be measured for step load changes, rapid load reduction, and plant trips.
Adequacy of radiation shielding will be verified by gamma and neutron radiation surveys at preselected locations throughout the plant at various power levels. Normal periodic sampling will be performed to verify the chemical and radio-chemical analysis of the reactor coolant.
14.2.11 Test Program Schedule Test sequence schedules for preoperational and power ascension testing are shown in Figures 14.2-1 and 14.2-2, respectively. These schedules show certain milestones at which time tests (or portions of tests) should be completed and the time frame in which the tests are expected to be performed.
These schedules represent a plan for completion of the initial test program which, from time-to-time, may be altered due to unforeseen circumstances. Detailed schedules for testing will be prepared, reviewed and revised on a continuing basis as plant construction progresses. Plant structures, systems, and components which are relied upon to prevent or mitigate consequences of postulated accidents will be fully tested to the extent practical prior to exceeding the 5% power level. This testing includes an RCS flow measurement using RCS elbow tap differential pressure measurements and engineering calculations prior to initial criticality. However, those testing activities which cannot reasonably be performed below the 5% power level will be fully tested to the extent practical prior to exceeding the 30% power level with the exception of the RCS Calorimetric Flow Measurement test which is performed at the 75% power level consistent with Westinghouse recommendations.
Preoperational testing of the various systems and components, which will continue up to fuel loading, is planned to commence approximately 12 months prior to fuel load.
Fuel load, initial criticality, and power ascension tests are scheduled to be accomplished over a period of approximately 5 months.
Certain systems will have part of the preoperational testing performed after fuel load due to system configuration (e.g., control rod drive mechanisms require fuel in the vessel to be fully tested). Such systems will be sufficiently tested prior to fuel load to provide reasonable assurance of successful testing after fuel load.
The development of test procedures will be an ongoing process, which will consist of preparation, review, and revision. Approved preoperational test procedures for satisfying FSAR testing commitments will be made available to NRC regional personnel a minimum of 60 days prior to their intended use. Power ascension test procedures will be made available 60 days prior to fuel load.
14.2-34 TEST PROGRAM
WATTS BAR WBNP-105 14.2.12 Individual Test Descriptions 14.2.12.1 Preoperational Tests The test summaries for each of the preoperational tests to be performed, along with an index to these summaries, are provided in Table 14.2-1. These summaries describe the various tests which are specified as preoperational tests in Regulatory Guide 1.68.
The scope and titles of these summaries may not in all cases correspond directly to the actual test procedures which will be used during the initial test program. Certain test procedures may include more than one test as described in these summaries, and in some cases tests described in one summary may be covered under more than one procedure. The overall scope and content of the tests described in these summaries will be addressed in final procedures.
The preoperational test summaries in Table 14.2-1 include general test methods such as the verification of instrumentation, controls, indications, interlocks, and protective devices. The functionality of such devices will be demonstrated during component testing. The completion of appropriate component tests will be verified prior to performance of preoperational tests as described by general prerequisite number two (2) below. It is not intended to reverify the functionality of all individual devices (e.g.,
instruments, relays, contacts, etc.) which have been previously verified by component tests. However, the important to safety design features (component response such as open, close, start, stop, etc.) which result from the operation of such devices will be demonstrated by system level preoperational tests.
There will be certain prerequisites which will apply in general to all preoperational tests.
These general prerequisites are listed here rather than included in each summary.
General Prerequisites:
(1) Construction activities have been completed (or exceptions justified) on the system and on the necessary portions of supporting systems and any deficiencies have been properly dispositioned.
(2) Functional operability of individual components or subsystems has been demonstrated for items such as valves, pumps, motors, instrumentation, and controls.
(3) Test equipment necessary for test performance is available and calibrated.
(4) Electrical power and air supplies are available as required for test performance.
14.2.12.2 Power Ascension Tests The Power Ascension phase of the initial test program consists of preoperational type tests deferred to the power ascension phase, power ascension tests performed prior to fuel loading, fuel load, precritical tests, initial criticality, low power physics tests TEST PROGRAM 14.2-35
WATTS BAR WBNP-105 (0-5%), and power ascension tests above 5% power. Test summaries providing descriptions of major power ascension testing are provided in Table 14.2-2, along with an index. The scope and titles of these summaries may not, in all cases, correspond directly to the actual test procedures which will be used during the power ascension test program. Certain test procedures may include more than one test, as described in these summaries, and in some cases, tests described in one summary may be covered under more than one procedure. The scope and content of the tests described in these summaries will be addressed in final procedures.

SUMMARY
OBJECTIVE To measure the rod drop and stationary gripper release time for each control and shutdown rod at hot standby conditions with full RCS flow.
PREREQUISITES
- 1. The reactor is in hot standby conditions at nominal operating temperature and pressure.
- 2. The NIS source range channels are operable and the CRDM cooling fans are available to provide ventilation.
- 3. All reactor coolant pumps are in operation.
TEST METHOD The shutdown and control rods will be partially withdrawn and the reactor trip breakers will be opened to demonstrate that all CRDMs unlatch and all rods fully insert into the core. The drop time for each shutdown and control rod will be measured by monitoring the time-variant voltage response of the associated rod position indication detector primary coil and stationary gripper coil. The rods will be dropped from the fully withdrawn position either by de-energizing the stationary gripper coils individually, or by opening the reactor trip breakers thus dropping all or a portion of the rods together. The rod drop and stationary gripper release times will be determined using a data collection system. Testing will be performed under hot. full-flow,conditions. Rods whose drop times are greater than two standard deviations from the average drop time for all rods will be retested at least 3 times to ensure that the rod drop times are consistent. The stationary gripper release times will be measured to verify that the requirements of Chapter 4 are satisfied.
NOTE: Additional rod drops may be performed at either hot or cold RCS conditions with any RCS flow condition. These drops are not used to satisfy acceptance criteria and their times are not included in calculating averages.
ACCEPTANCE CRITERIA

SUMMARY
OBJECTIVE To achieve initial criticality in a cautious and controlled manner.
PREREQUISITES

- 2. Source, intermediate and power range channels are calibrated and in operation. Power Range High Flux Trip setpoints are set to less than or equal to 20% power.
- 3. A minimum count rate of 2 cps and a signal to noise ratio of greater than 2 is verified on the source range channels.
- 4. The RCS is at hot no load pressure and temperature.
TEST METHOD After establishing baseline count rates, the shutdown (if not previously pulled) and control banks are withdrawn in normal sequence until approximately 100 pcm worth remains inserted. RCS boron dilution is commenced at a rate of approximately 1000 pcm per hour with the RCS boron concentration being sampled at approximately 30 minute intervals. When the Inverse Count Rate Ratio (ICRR) is approximately 0.3, dilution rate is diminished by at least half of the original rate and ICRRs are renormalized to 1. Dilution is continued until the ICRR is approximately 0.2. Then dilution is terminated and the RCS is allowed to mix. If criticality is not achieved during mixing, the withdrawal of control bank D will be performed to achieve criticality. If criticality is not achieved when control bank D is fully withdrawn, control bank D will be reinserted to its original position. ICRR data will be renormalized and dilution will be initiated to add approximately 20 to 100 pcm of positive reactivity and the dilution will then be terminated.
The RCS is allowed to mix. If criticality is not achieved during mixing, then control bank D is withdrawn until criticality is achieved. If criticality is not achieved when control bank D is fully withdrawn, control bank D will again be reinserted to its original position and the evolution will be repeated until criticality is achieved. During dilution, plots of ICRR versus time and ICRR versus dilution water additions are maintained.
ACCEPTANCE CRITERIA The reactor achieves initial criticality in a safe and orderly manner.

SUMMARY
OBJECTIVE To demonstrate the ability of primary and secondary side systems to bring the unit to stable conditions following a turbine trip resulting from the opening of the generator output breaker and to determine the overall response time of the RCS narrow range hot leg RTDs.
PREREQUISITES
- 1. The reactor is stable at the 100% power test plateau.
- 2. Pressurizer pressure, pressurizer level, steam dump, steam generator level, and feedwater pump speed controls are in automatic.
- 3. The electrical distribution system for the unit is in normal full power alignment.
TEST METHOD Recorders are connected to monitor plant parameters (e.g., reactor power, RCS temperature and pressure, pressurizer level, feedwater and steam flows, steam generator levels, feedwater pump speed, feedwater pressure, generator breaker position, and turbine speed) during the transient. The transient is initiated by opening the generator output breaker from the control room. The turbine trips as a direct result of opening the generator output breaker. A reactor trip follows the turbine trip, and plant parameters are allowed to stabilize. Operators may take manual control of plant systems as directed by operating procedures.
ACCEPTANCE CRITERIA
- 1. A safety injection is not initiated.
- 2. Pressurizer and steam generator safety valves do not lift.
- 4. The reactor trips.

WATTS BAR WBNP-105 Table 14.2-2 (Sheet 37 of 39) REACTOR VESSEL LEVEL INSTRUMENTATION SYSTEM (RVLIS) TEST
SUMMARY
OBJECTIVE To collect RVLIS data during power ascension in order to determine the RVLIS scaling coefficients.
PREREQUISITES
- 1. The reactor core has been loaded.
- 2. The RCS is filled and vented.
- 3. Dynamic range RVLIS is operational.
TEST METHOD At the beginning of plant heatup with RCP's running in various combinations, data is collected from the dynamic range RVLIS, wide range RTDs and wide range pressure instrumentation. Data will continue to be collected during heatup. Data collection with the various RCP combinations will be repeated at 557°F.
The zero power level scaling coefficients may then be entered, if deemed necessary, and a verification that RVLIS will compensate for RCP status changes will be made. As the plant escalates to 100% power the two dynamic RVLIS trains are monitored. At 100% power the full power scaling coefficient are determined.
ACCEPTANCE CRITERIA After the full power scaling coefficient have been entered the two dynamic RVLIS trains are to track within the limits specified by the vendor.
