BVPS UFSAR UNIT 1 Rev. 19 SECTION 13 INITIAL TESTS AND OPERATION
13.0 INTRODUCTION
This section describes the scope of tests and operations to be performed when construction is complete enough to operate and test individual components and systems through the 100 continuous hours acceptance run of full power for commercial operation. This test period is divided into two categories:
- 1. Preoperational testing generally refers to those tests performed prior to the initial core loading
- 2. Initial startup testing generally refers to those tests and operations from the initial core loading through the acceptance tests.
In the preparation of this section, the following AEC Guides were used as a guide for determining the tests to be performed:
- 1. "Guide for the Planning of Preoperational Testing Programs", USAEC, December 7, 1970
- 2. "Guide for the Planning of Initial Startup Programs", USAEC, December 7, 1970 (revised).
It should be noted that some of the tests described in the guides are considered preoperational tests, but because of their requirements, are performed during startup testing. An example is scram performance of control rods. This can only be done after the core is loaded and the vessel head is on, although this test appears in the Preoperational Guide. In such cases, the tests are addressed in the order of appearance in the guides to facilitate review. A notation specifies any deviation from the performance of a test outside of the time period in which it is categorized.
Administrative Procedures for Conducting the Test Program The entire test program and operations will be under the direct control of Duquesne Light Company via the Joint Test Group (Refer to Section 13.2), including the preparation of test documents and performance of the tests. During the procedure preparation and test performance, technical assistance will be provided by Duquesne Light Company's contractors as deemed necessary. Detailed procedures will be prepared by Duquesne Light Company from design information, test specifications and procedures provided by Duquesne Light Company's contractors and equipment manufacturers. Prior to issuance of test procedures for performance, a review will be conducted with the Duquesne Light Company Organization and by the Joint Test Group.
Testing is conducted by Duquesne Light Company's personnel technically assisted as required by the contractor personnel. Test results will be evaluated and approved by Duquesne Light Company and the Joint Test Group.
13.0-1
BVPS UFSAR UNIT 1 Rev. 19 Changes to approved test procedures will be documented and will become part of the final test procedures. The procedure for making these changes, including the reviews and approvals, is covered in detail in Section 13.2.
Personnel performing the tests will be part of the startup and operation organization and will be qualified by experience and training to perform these activities as stated in Section 13.2. These personnel will be under the supervision of the BVPS-1 Superintendent, Licensed Senior Operators and the Technical Supervisor.
Results of tests will be fully documented and reviewed as stated in Section 13.2. As appropriate, results will be incorporated in unit operating procedures. Any modification required to equipment during the performance of testing or as required based on test data will be documented and become part of the official unit records. Temporary changes to systems will be documented in the procedures and following completion of test will be restored to normal conditions and verified.
At the conclusion of each test, the completed test procedures along with all data and conclusions will be documented and filed as part of the permanent unit records.
13.0-2
BVPS UFSAR UNIT 1 Rev. 19 13.1 TEST PROGRAM 13.1.1 Preoperational Test Program The comprehensive testing program ensures that equipment and systems perform in accordance with design criteria prior to fuel loading. As the installation of individual components and systems is completed, they are tested and evaluated according to pre-determined and approved written testing techniques, procedures or check-off lists. Analyses of test results are made to verify that systems and components are performing satisfactorily and if not, to provide a basis for recommended corrective action.
The program includes tests, adjustments, calibrations and system operations necessary to ensure that initial fuel loading, initial criticality and subsequent power operation can be safely undertaken.
Whenever possible these tests are performed under the same conditions as experienced under subsequent unit operations. During system tests for which unit parameters are not available and cannot be simulated due to existing unit conditions the systems are operationally tested as far as possible without these parameters. The remainder of the tests are performed under unit conditions when the parameters are available. Abnormal unit conditions are simulated during testing when required and when such conditions do not endanger personnel or equipment or contaminate systems whose cleanliness has been established.
In general, preoperational testing is completed prior to core loading. As individual systems are completed, preoperational tests are performed to verify as near as possible, the performance of the system under actual operating conditions. Where required, simulated signals or inputs are used to verify the full operating range of the system and to calibrate and align the systems and instruments at these conditions. Later systems that are used during normal operation are verified and calibrated under actual operating conditions. Systems that are not used during normal unit operation, but must be in a state of readiness to perform safety functions, are checked under all modes and test conditions prior to unit startup. Examples of these systems are reactor trip system and engineered safety features system logic, operation checks and setpoint verifications.
Testing performed during the preoperational test program is outlined in Table 13.1-1 and shown in sequence of performance in Figure 13.1-1. In general, it is expected that all preoperational testing will be completed before fuel loading. In some cases, it will be necessary to defer certain preoperational tests until after core loading. These include such tests as the complete rod control system, rod position indication and complete in-core moveable detector system.
These tests have been identified in Table 13.1-1. Prior to the performance of hot testing, following core loading, prerequisite cold testing will have been performed. Examples of these tests are the cold rod drop time measurement tests.
An instrumented piping preoperational vibration test program to measure the frequency and amplitude of piping systems utilizing recording accelerometers (time dependent) will be conducted, under simulated transients that are credible within the normal and upset operating modes of the most susceptible Class I piping systems. The simulated transients that will be performed during these instrumented tests will include:
13.1-1
- 1. Start and stop reactor coolant pumps with associated operation of valves (closures/openings) in reactor coolant piping systems
- 2. Start and stop residual heat removal (RHR) pumps with normal operation (closures/openings) of the associated valves in RHR piping systems
- 3. Operation of the safety injection piping system, including direct injection into the primary coolant loop
- 4. Operation of pressurizer relief valves and its associated discharge piping system
- 5. Start and stop auxiliary feedwater pump with normal operation (closures/openings) of the associated valves in the auxiliary feedwater piping system.
On all other Seismic Class I piping systems, non-instrumented vibratory test programs will be implemented during the preoperational test program. If excessive vibration is observed under the transient loadings specified in Section 13 and Appendix B, either restraints will be installed or an instrumented test program will be performed.
For instrumented test programs, the amplitude of the measured dynamic responses at predetermined points of piping systems will be converted to a dynamic stress intensity equivalence, to be combined with other primary stresses. The acceptable criteria will be based on the allowable primary stress limit of 1.25Sh as specified in ANSI-B31.1. Power Piping Code.
13.1.2 Initial Startup Test Program Fuel loading begins when all prerequisite system tests and operations are satisfactorily completed. Upon completion of fuel loading, the reactor upper internals and pressure vessel head are installed and additional mechanical and electrical tests are performed as discussed in preoperational testing. The purpose of this phase of activities is to prepare the system for nuclear operation and to establish that all design requirements necessary for operation are achieved. The core loading and post loading tests are described below.
13.1.2.1 Fuel Loading The reactor containment structure shall be completed and the containment integrity established and maintained during fuel loading.
Fuel handling tools and equipment shall have been checked out and dry runs conducted in the use and operation of equipment.
The reactor vessel and associated components will be in a state of readiness to receive fuel.
Water level will be maintained above the bottom of the nozzles and recirculation maintained to ensure a uniform boron concentration. Boron concentration can be increased via the RHR system or directly to the open vessel.
13.1-2
BVPS UFSAR UNIT 1 Rev. 19 The overall responsibility and direction for initial core loading is exercised by the station management. The overall process of initial core loading is, in general, directed from the charging floor of the containment structure. Procedures for the control of personnel and the maintenance of containment integrity are established prior to the fuel loading.
The as-loaded core configuration is specified as part of the core design studies conducted well in advance of station startup and as such is not subject to change at startup. In the event that mechanical damage is sustained during core loading operations to a fuel assembly of a type for which no spare is available onsite, an alternate core loading scheme whose characteristics closely approximate those of the initially prescribed pattern will be determined.
The core is assembled in the reactor vessel, submerged in reactor grade water containing enough dissolved boric acid to maintain a calculated core effective multiplication factor of 0.90 or lower. The refueling cavity is dry during initial core loading. Core moderator chemistry conditions (particularly, boron concentration) are prescribed in the core loading procedure document and are verified periodically by chemical analysis or moderator samples taken prior to and during core loading operations.
Core loading instrumentation consists of two permanently installed source range (pulse type) nuclear channels and two temporary incore source range channels plus a third temporary channel which can be used as a spare. The permanent channels when responding are monitored in the main control room by licensed station operators; the temporary channels are installed in the containment structure and are monitored by reactor engineering personnel and licensed station operators. At least one permanent channel is equipped with an audible count rate indicator. Both unit channels have the capability of displaying the neutron flux level on a strip chart recorder. The temporary channels indicate on rate meters with a minimum of 1 channel recorded on a strip chart recorder. Minimum count rates of two counts per second, attributable to core neutrons, are required on at least two of the four (i.e., 2 temporary and 2 permanent source range detectors) available nuclear source channels at all times following installation of the initial nucleus of eight fuel assemblies.
At least two artificial neutron sources are introduced into the core at appropriate specified points in the core loading program to ensure a neutron population of a minimum of 2 counts per second for adequate monitoring of the core.
Fuel assemblies together with inserted components (control rod assemblies, burnable poison inserts, source spider or thimble plugging devices) are placed in the reactor vessel one at a time according to a previously established and approved sequence which was developed to provide reliable core monitoring with minimum possibility of core mechanical damage. The core loading procedure documents include detailed tabular check sheets which prescribe and verify the successive movements of each fuel assembly and its specified inserts from its initial position in the storage racks to its final position in the core. Multiple checks are made of component serial numbers, types and orientation at successive transfer points to guard against possible inadvertent exchanges or substitutions of components and fuel assembly status boards are maintained throughout the core loading operation.
An initial nucleus of eight fuel assemblies, the first of which contains an activated neutron source, is the minimum source-fuel nucleus which permits subsequent meaningful inverse count rate monitoring. This initial nucleus is determined by calculation and previous experience to be markedly subcritical (keff < 0.90) under the required conditions of loading.
13.1-3
BVPS UFSAR UNIT 1 Rev. 19 Each subsequent fuel addition is accompanied by detailed neutron count rate monitoring to determine that the just loaded fuel assembly does not excessively increase the count rate and that the extrapolated inverse count rate ratio is not decreasing for unexplained reasons. The results of each loading step are evaluated before the next prescribed step is started.
Criteria for safe loading require that loading operations stop immediately if:
- 1. An unanticipated increase in the neutron count rates by a factor of 2 occurs on all responding nuclear channels during any single loading step after the initial nucleus of 8 fuel assemblies are loaded (excluding anticipated change due to detector and/or source movement).
- 2. The neutron count rate of any individual nuclear channel increases by a factor of five during any single loading step after the initial nucleus of 8 fuel assemblies are loaded (excluding anticipated changes due to detector and/or source movements).
An alarm in the containment and main control room is coupled to the source range channels with a setpoint at 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 the evacuation alarm is actuated during core loading and after it has been determined that no hazards to personnel exist, preselected personnel are permitted to re-enter the containment vessel to evaluate the cause and determine future action.
Core loading procedures specify the condition of 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, identify responsibility and authority and provide for continuous and complete fuel and core component accountability.
13.1.2.2 Postloading Tests Upon completion of core loading, the reactor upper internals and the pressure vessel head are installed and additional mechanical and electrical tests are performed prior to initial criticality.
The final pressure test is conducted after filling and venting is completed to check the integrity of the vessel head installation.
Mechanical and electrical tests are performed on the control rod drive mechanisms. These tests include a complete operational checkout of the mechanisms and calibration of each individual rod position indication.
Tests are performed on the reactor trip circuits to test manual trip operation. The actual control rod assembly drop times are measured for each control rod assembly. The reactor control and protection system is checked with simulated signals to produce a trip signal for the various conditions that require unit trip.
At all times that the control rod drive mechanisms are being tested, the boron concentration in the coolant-moderator is maintained such that criticality cannot be achieved with all control rod assemblies out.
13.1-4
BVPS UFSAR UNIT 1 Rev. 19 A complete functional electrical and mechanical check is made of the incore nuclear flux mapping system at the operating temperature and pressure.
After final precritical tests, nuclear operation of the reactor begins. This final phase of startup and testing includes initial criticality, low power testing and power level escalation. The purpose of these tests is to establish the operational characteristics of the unit and core, to acquire data for the proper calibration of setpoints, and to ensure that operation is within license requirements. A brief description of the testing is presented in the following sections. Table 13.1-2 summarizes the tests which are performed from initial core loading to rated power and Figure 13.1-2 shows the sequence in which these tests are performed.
Initial criticality is established by sequentially withdrawing the shutdown and control groups of control rod assemblies from the core, leaving the last withdrawn full length control group inserted far enough in the core to provide effective control when criticality is achieved, and then continuously diluting the heavily borated reactor coolant until the criticality is achieved.
Successive stages of control rod assembly group withdrawal and of boron concentration reduction are monitored by observing changes in neutron count rate as indicated by the normal unit source range nuclear instrumentation as functions of group position during rod motion and, subsequently, of reactor coolant boron concentration and primary water addition to the reactor coolant system during dilution. Throughout this period, samples of the primary coolant are obtained and analyzed for boron concentration.
Inverse count rate ratio monitoring is used as an indication of the proximity and rate of approach to criticality of the core during control rod assembly group withdrawal and during reactor coolant boron dilution. The rate of approach is reduced as the reactor approaches the time extrapolated for criticality to ensure that effective control is maintained at all times. Written procedures specify the unit conditions, precautions and specific instructions for the approach to criticality.
13.1.2.3 Low Power Testing A prescribed program of reactor physics measurements is undertaken to verify that the basic static and kinetic characteristics of the core are as expected and that the values of the kinetic coefficients assumed in the safety analysis are indeed conservative.
The measurements are made at low power and primarily at or near operating temperature and pressure. Measurements, to include verification of calculated values of control rod assembly group reactivity worths, of isothermal temperature coefficient under various core conditions, of differential boron concentration reactivity worth and of critical boron concentrations as functions of control rod assembly group configuration are made.
In addition, measurements of the relative power distributions are made. Concurrent tests are conducted on the instrumentation including the source and intermediate range nuclear channels.
Procedures are prepared to specify the sequence of tests and measurements to be conducted and the conditions under which each is to be performed to ensure both safety of operation and the relevancy and consistency of the results obtained. If significant deviations from design predictions exist, unacceptable behavior is revealed, or apparent anomalies develop, the testing is suspended and the situation reviewed to determine whether a question of safety is involved, prior to resumption of testing.
13.1-5
BVPS UFSAR UNIT 1 Rev. 19 13.1.2.4 Power Level Escalation When the operating characteristics of the reactor and unit are verified by the low power testing, a program of power level escalation in successive stages brings the unit to its full rated power level. Both reactor and unit operational characteristics are closely examined at each stage and the conformance with the safety analysis verified before escalation to the next programmed level is effected.
Measurements are made to determine the relative power distribution in the core as functions of power level and control assembly group position.
Secondary system heat balances ensure that the indications of power level are consistent and provide bases for calibration of the power range nuclear 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 is verified.
At prescribed power levels the dynamic response characteristics of the reactor coolant and steam systems are evaluated. The responses of the systems are measured for design step load changes of 10 percent, rapid 50 percent load reduction, and turbine trips.
Adequacy of radiation shielding is verified by gamma and neutron radiation surveys at selected points inside the containment and throughout the station site at various power levels. Periodic sampling is performed to verify the chemical and radio-chemical analysis of the reactor coolant.
Testing performed following core loading and during unit startup is outlined in Table 13.1-2. All precritical tests shall be completed prior to initial criticality and the results evaluated.
Prerequisites for performing a test are specified in the individual test procedure. The sequence of testing is outlined in a startup test sequence, such that required prerequisite testing is completed prior to performing subsequent testing. Any special test instruments required are specified to be installed, calibrated and checked in the test procedure that specifies the test equipment. Where these test instruments are not left installed for future use, they are removed from the systems and removal is verified. The sequence of testing following core loading is shown by Figure 13.1-2. The sequence of testing may be modified in accordance with the BVPS-1 Test Program Administrative Procedures.
13.1.2.5 Augmented Startup Program The BVPS-1 augmented startup program will be performed as indicated in Reference 1. There are two phases of the program; one consisting of additional startup testing and the second consisting of additional periodic at-power cycle testing. The purpose of the program is to obtain additional confirmation of the nuclear design bases for peaking factor calculations by conducting incore flux measurements under nonsteady-state conditions. These conditions include additional load following maneuvers and also special maneuvers whereby the axial flux difference is forced to the extreme of Technical Specification limits under constant axial offset power distribution control so as to approximate, as far as practicable, the most limiting power distributions which establish the peaking factor design envelope. Full core and special quarter core flux maps are taken throughout the resulting transient. Xenon conditions are compared with the corresponding calculated power distribution behavior. Testing will be performed at approximately 50, 75, 90 and 100 percent power levels with the exception of the fast ramp load follow test, which will not be performed.

13.1-7
BVPS UFSAR UNIT 1 Rev. 19 13.2 TEST PROGRAM RESPONSIBILITIES AND IMPLEMENTATION The Duquesne Light Company has the overall responsibility for development, supervision, performance and documentation of all of the preoperational and startup testing of the Beaver Valley Power Station Unit No. 1 (BVPS-1). Test procedure preparation and all test performance at BVPS-1 are under the control of Duquesne Light Company to ensure proper and effective emphasis is maintained on personnel and plant safety by all individuals participating in the testing program.
The BVPS-1 preoperational and startup test program objective is to prove conclusively the plant readiness and capability to operate safely within its designed limits. Included in the program shall be tests to verify the plants adequacy to cope with transient and accident conditions without endangering the health and safety of the general public.
Successful completion of the test programs will constitute a reasonable assurance that the plant can operate safely by demonstrating the knowledge and operating competence of the organization responsible for plant operation. Operation under abnormal or emergency conditions will have been tested by establishing suitable environmental conditions as closely as can reasonably be established or simulated to ensure the adequacy of the abnormal and emergency operating procedures. Concurrently, the adequacy of normal operating and test procedures as well as administrative controls will be confirmed. The operating experience gained during the test program provides additional training for station operations personnel complementing previous experience and training detailed in Section 12.
In order to accomplish these preoperational and startup testing objectives of BVPS-1 with a maximum assurance of safety and acceptability, a Joint Test Group has been created. This group consists of a qualified representative from Duquesne Light Company (applicant), Stone &
Webster Company (constructor-engineer) and Westinghouse Electric Corporation (nuclear steam supply system vendor). The Duquesne Light Company representative is the Technical Assistant-Nuclear to the Manager, Power Production, who will act as chairman of the Joint Test Group. Alternates for each individual will be named to permit continuous performance of the group. This group will function in the capacities described below until Duquesne Light Company has formally accepted BVPS-1 for commercial operation. At that time, the responsibilities of the Joint Test Group will be assumed entirely by Duquesne Light Company.
The Joint Test Group is assigned the specific responsibility for coordination and performance of the organizations involved in accomplishing the successful completion of BVPS-1 preoperational and startup test program. They are responsible for review and approval of test schedules, test procedures, test evaluations and test modifications. The details of accomplishment of these efforts are explained later in this section.
The establishment of this group assures that each test schedule, procedure, and any modifications thereto, have been thoroughly reviewed for acceptability by all responsible parties prior to approval for performance. This provides the necessary control for preparation, coordination, performance and modification of the various tests and ensures they have been accurately and thoroughly evaluated to preclude incomplete or erroneous conclusions.
13.2-1
BVPS UFSAR UNIT 1 Rev. 19 The scope of the preoperational and startup test programs and the responsibilities of the Joint Test Group will extend beyond safety-related systems though not necessarily incorporated in this document. The preoperational and startup test programs, when completed, will provide assurance that the plant will perform in accordance with the Technical Specifications approved for BVPS-1 and that all tests dictated in Sections 3 through 11 have been successfully performed and documented.
All plant systems operations required by the preoperational and startup test program are performed by authorized BVPS-1 operations personnel in cooperation with and under the cognizance of the BVPS-1 Test Section. The BVPS-1 Test Section consist of engineers who function under the direct supervision of the Technical Supervisor.
This group is charged principally with:
- 1. Preparation of draft test procedures
- 2. Final draft and issuance of approved test procedures
- 3. Incorporation of comments and issuance of approved modified test procedures
- 4. Providing technical assistance and resolution in the performance of tests (in cooperation with operations Shift Supervisor)
- 5. Compilation of test data
- 6. Issuance of test results reports
- 7. Maintaining and controlling active test schedules
- 8. Maintaining files of all test schedules, test procedures, test data and test results reports
- 9. Administrative control of the test program in-plant
- 10. All other responsibilities normally associated with the above listed efforts (i.e., determine and obtain reference documents and technical assistance for test procedure preparation and evaluation, assurance of adequacy of test devices and equipment to be used in any tests, provide number of qualified technical personnel to perform test, operate special test equipment, verify temporary test arrangements are properly installed and removed when necessary, etc.).
All operating personnel will be qualified, trained and appropriately licensed as prescribed by law.
Supervision will be by licensed senior reactor operators and reactor operations will be performed by licensed reactor operators. Senior management and technical support personnel have been assigned on the basis of prior reactor plant operating and test experience and training. In most cases, these persons are licensed or have been previously certified in reactor operations (for more detail of qualifications and assignation refer to Section 12 and the BVPS-1 Technical Specifications).
13.2-2
BVPS UFSAR UNIT 1 Rev. 19 Fuel loading will be performed principally by station operations personnel supervised by licensed senior reactor operators. Fueling procedures will follow a similar evolution (from draft through results documentation) as test procedures. Supervision and technical assistance will be supplemented by qualified Westinghouse (nuclear steam system supplier) technical personnel. Test Section engineers will be assigned during fuel load performance to assist in fulfilling the necessary inspection, identification, verification, core status monitoring, recording, documentation and such tasks which can most effectively be accomplished with technically oriented personnel.
All proof testing performed prior to preoperational testing will be verified by a check of documentation as required by each test procedure. The format, method of preparation and approval of detailed test procedures is described below. For the purpose of illustration, a listing of representative tests is given in Table 13.1-1; however, additional nonsafety related and specific plant tests will be included but are not necessarily herein documented. Integrated hot functional tests including simultaneous operation of auxiliary systems will be carried out formally as will overall plant performance in so far as practicable to accomplish that test objective as required. Where test or test aspects are not practical, simulation will be exercised to its practical limit.
Test procedure preparation shall commence sufficiently in advance of the scheduled tests so as not to interfere with the orderly accomplishment of the test program. The magnitude of the effort involved with test procedure preparation will vary based on estimates of the number of tests and when they are needed which is determined by the preoperational and startup test program schedule.
The following discussion describes the preparation, review and approval process, and the execution of BVPS-1 test procedures as well as the evaluation, documentation and approval of test results. The organizational responsibilities and qualifications are also included. The administrative procedures for initial issuance or modification to test procedures (refer to Figure 13.2-1) are also discussed.
The preoperational and startup test procedures are initially drafted by the Test Section engineers utilizing general test schedules and specifications generated by the Stone & Webster Engineering Corporation (S&W) or by the Westinghouse Electric Corporation (W). These draft test procedures are reviewed by the BVPS-1 Operations Group (and Onsite Safety Committee where appropriate) and any comments are resolved and/or incorporated into the procedure by the Test Section (See Figure 13.2-1). Comments of the BVPS-1 Health Physics and Chemistry Group and/or the Maintenance Group are also solicited where appropriate. When the BVPS-1 Operations personnel and Test Section completes a test procedure for Joint Test Group approval, copies of that procedure are submitted to the Joint Test Group. The Joint Test Group then distributes the procedure to their cognizant designers and/or constructors for further review and comment. At subsequent meetings of the Joint Test Group, the issued test procedure is reviewed and any engineering constructor or nuclear steam supplier comments, changes, additions or deletions are resolved. The Joint Test Group returns that test procedure to the Test Section where it is revised as recommended by the Joint Test Group. The test procedure is then issued in final form for approval by the Joint Test Group. Each of the individuals of the Joint Test Group will signify approval of the procedure by signature and date in the space provided on the cover sheet of the test procedure. The nuclear steam supply system representative of the Joint Test Group will not normally approve test procedures which deal with components or systems beyond the nuclear steam supply system engineers scope of interest.
The nuclear steam supply system representative signature on these procedures are in a 13.2-3
BVPS UFSAR UNIT 1 Rev. 19 separate space and does not indicate approval but does indicate the nuclear steam supply representative has had the opportunity to comment and acknowledges that performance of the procedure does not detrimentally effect equipment or systems under his area of responsibility.
The original signed procedure is retained in the files of the Test Section. Copies of this procedure will be made and sent to the BVPS-1 Operations Group, the engineer constructors, and the nuclear steam supply representative (as necessary).
Additionally, where loading of fuel in the reactor vessel commences, it will be necessary for the Onsite Safety Committee (refer to Section 12.5) to review in detail all tests involving reactivity control systems or engineered safeguards systems. This review deals with the scheduling of the tests, the test procedures as approved and the test evaluations as issued.
The BVPS-1 Superintendent signifies by his signature concurrence of the Onsite Safety Committee. The Onsite Safety Committee will determine on an individual case basis, whether review by the Offsite Review Committee is specifically required.
The BVPS-1 test procedures will consist principally of the following:
- 1. COVER PAGE: A descriptive title, issue date, identifying symbol, Test Section revision number and an approval signature section.
- 2. PURPOSE OF TEST: A brief statement as to the objective or reason for performing the test. All applicable BVPS-1 Technical Specifications will be referenced and reference may also be made to other sections of this FSAR, equipment specifications, etc.
- 3. GENERAL TEST METHOD: A brief discussion of the manner in which the test will be performed. This discussion does not go into the step by step sequence, but should be sufficiently detailed that the reader will understand how the test is to be conducted.
- 4. SPECIAL TEST EQUIPMENT: This section should list in detail what equipment, other than installed operational equipment and instruments, is required to obtain the required data or to perform the test.
- 5. PREREQUISITES: A list of items, events or actions that must be completed prior to the start of a test. Included will be such items as a check that necessary quality assurance documentation has been completed and in certain cases, a field inspection to establish that the systems are ready for testing. All other tests or portions of tests that must have been satisfactorily completed and all test equipment that must be calibrated or otherwise made operable and any environmental conditions, if applicable, and not covered under Initial Station Conditions will be included in the prerequisites.
- 6. INITIAL STATION (SYSTEM) CONDITIONS: A list of conditions that the station or system must be in at the start of the test performance. This section may make reference to appropriate station operating procedures but should be specific as to conditions of the station and/or systems affected.
13.2-4
- 7. PRECAUTIONS AND LIMITATIONS: This should be a precise list of all applicable precautions that are to be taken prior to, during and following performance of the test. These should cover the safety of personnel and operating equipment, identifying protective devices, apparel, personnel conduct and any items related to safety. All limitations that will be or possibly could be approached are to be clearly stated.
- 8. PROCEDURE: The procedure is written in a step by step manner as required to direct the persons performing the test. It should also indicate when data is recorded, which specific instruments are read and the frequency of recording data. For procedures which are anticipated to be performed only once, the data sheets may be found in this section. Any contingencies are provided for in this section. All temporary changes made in plant are required to be restored to normal in this section following test performance unless required as a prerequisite for a subsequent test. If so, it is so stated and requires that such subsequent action follows directly and that its procedure requires restoration of temporary plant changes.
- 9. ACCEPTANCE CRITERIA: States as clearly as possible the criteria that must be met to consider the test results satisfactory, and ultimately, the test completed. The source of the acceptance criteria will normally be identified as well as referenced. If no acceptance criteria is available or clearly defined, it shall be so pointed out as well as designated an authority for resolution of the problem. A copy of both the test procedure and data must be placed on file with the DLC Test Section.
- 10.
REFERENCE:
A list of all sources of information considered necessary for the successful completion of the test procedures.
- 11. DATA SHEETS: For test procedures that will be of a periodic nature or where the required data is too extensive to be included in Item 8 above, recording data sheets will be provided at the end of the procedure.
All operations supervision is instructed that tests are only performed in accordance with approved test procedures. If it is not possible to perform the test as specified by the approved test procedure, the test may not be performed until the procedure is altered or modified as necessary and authorized. Any change(s) to an approved test procedure are dealt with by the Joint Test Group in a manner similar to the method specified for incorporating comments into a draft test procedure. Where it is not possible to perform the test safely and with acceptable results in accordance with the approved test procedure, and it is not prudent to delay performance of the test to allow necessary procedure changes to be incorporated in accordance with the above specified manner, an alternate approved method may be used.
13.2-5
BVPS UFSAR UNIT 1 Rev. 19 Within the DLC BVPS-1 organization, the on-duty Shift Supervisor and responsible Test Engineer on-shift are authorized by the Joint Test Group on a predefined limited basis to make required minor changes or modifications to the approved test procedure. The on-duty Shift Supervisor is responsible for ensuring that the changes to the approved procedure do not compromise station or personnel safety while the responsible Test Section engineer ensures that the results of the test are not compromised. Where the change to the procedure results in a change in the scope of the test or alters the acceptance criteria, the Duquesne Light Company on-shift personnel will contact by phone their respective supervisors prior to approving the change. The Station Superintendent (Chief Engineer in his absence) may authorize the change for both the Operations Group and Test Section. When the test procedure concerns the nuclear or safety-related portion of the station, the On-Site Safety Committee Chairman or Vice Chairman will be contacted to determine the degree of participation by the On-Site Safety Committee prior to approving modifications to an already approved procedure.
The on-duty Shift Supervisor will authorize the Test Section engineer to make the necessary "pen and ink" changes to the approved test procedure and to the Operations Group, the constructor-engineer and the nuclear steam supplier copies of the approved procedure. The changes incorporated in the procedure will be specifically listed on the cover sheet of the procedure. The on-duty Shift Supervisor, responsible BVPS-1 Test Section engineer, the constructor-engineer and the nuclear steam supplier (if necessary) shift personnel will initial the cover sheet of the procedures indicating their approval of the change. It is the responsibility of those representatives initialing the change to secure authorization necessary from their own organization prior to initialing the change. If any representative withholds approval of the change, the test is to be delayed or suspended and the Joint Test Group will resolve any problems.
All operations supervisors and Test Section engineers are instructed that this alternate method of changing approved test procedures shall not be used to make changes to Joint Test Group approved procedures for reasons of station or personnel convenience. All tests must be performed in accordance with the approved procedure. Changes to the approved procedure that if incorporated, would significantly improve the utilization of the station or personnel will be noted by the on-shift Test Section engineer. These changes can be forwarded to the Joint Test Group with a recommendation of consideration for formal incorporation.
For many of the tests performed during the overall BVPS-1 preoperational and startup effort, specific acceptance criteria are included within the test procedure as stated above. This allows on-shift evaluation of the results and the test and some determination whether or not the test may be suspended, extended or repeated. For some tests, where it is not possible or practical to state specific acceptance criteria, general acceptance criteria are included to assist on-shift determination, with a detailed evaluation of the results of the test conducted subsequent to the completion of the test.
All of the data obtained during the test are retained by the Test Section and will be filed for future reference.
13.2-6
BVPS UFSAR UNIT 1 Rev. 19 Should any question exist on the adequacy of test results, the Joint Test Group will assign responsibility for preparing a written evaluation of the results of a test in the form of a test results report to an individual organization of the Joint Test Group. The Test Section prepares and issues written evaluations of the results of tests performed by the Duquesne Light Company.
The Test Section may contact the constructor-engineer or nuclear steam supplier to utilize their expertise if considered needed to properly evaluate the results of tests. For some of the less complex acceptance tests, the test result report may conceivably consist of a brief statement of the acceptance criteria and acknowledgement that it was satisfactorily met. For the complex tests, a more extensive test result report is submitted.
All test reports and evaluations are sent to the Joint Test Group for approval of evaluation.
Should any one member of the Joint Test Group question the adequacy or conclusion(s) of the report as issued, the Joint Test Group resolves the question(s) and authorizes the originating organization to issue a revised test result report for approval. The Joint Test Group also determines if a test must be repeated to obtain acceptable results. The members of the Joint Test Group (the nuclear steam supplier as necessary) indicates approval of the report by affixing their signatures in the applicable spaces provided on the test result report. The signed report is sent to the Test Section where copies are made and distributed to those persons or organizations which approved the respective test procedure which yielded the results. The original signed test result report is retained on file by the Test Section for record and future reference.
Should any deficiencies be discovered, discrepancies develop and/or modification to systems be required, these are noted in the test report. The party or organization responsible for performing corrective action is determined and notified by the Joint Test Group. Following completion of the required corrective action, the Joint Test Group determines if a test must be performed in its entirety or only a certain portion(s) of the test need be repeated. In most cases, the subsequent test and evaluation are handled as if it were a separate test to assure satisfactory documentation of the corrective action.
Following successful completion of the BVPS-1 preoperational and startup test program, the Joint Test Group is dissolved and all approval and disapproval functions, relating to station testing, which were the responsibility of this group, will become the responsibility of the BVPS-1 Station Superintendent.
During the preoperational and startup test program, the Test Section will be augmented as necessary with sufficient qualified technical personnel to assist in the research and preparation of test procedures, test performances, test evaluations and documentation of test results.
These supplemental personnel will be provided primarily by the Technical Services Section of the Power Stations Department and the Engineering and Construction Division at Duquesne Light Company. Additional assistance may be obtained through contracting with qualified consulting agencies.
As previously stated, the overall control for safe and complete accomplishment of the BVPS-1 preoperational and startup test program is the delegated responsibility of the Joint Test Group.
13.2-7
BVPS UFSAR UNIT 1 Rev. 19 The qualifications of the Joint Test Group are as follows:
The Chairman and Duquesne Light Company representative was the Technical Assistant-Nuclear to the Manager, Power Production. This position was held by Mr. John Carey. Mr.
Carey had sixteen years of power plant experience, the last four of which had been nuclear. He is a graduate electrical engineer and had successfully completed several nuclear training courses including the complete Shippingport Training Course and Westinghouse Nuclear Power Plant Simulator Course. He had spent three years as the BVPS-1 Station Superintendent and three years as the Station Superintendent of a fossil fired power station.
The nuclear steam supply systems contractor representative on the Joint Test Group was designated as the Westinghouse BVPS-1 Site Service Manager. This was Mr. Donald Wieland.
Mr. Wieland had thirteen years of experience with Westinghouse specifically dealing with Nuclear Power Plants in the area of construction and start up. His efforts were backed by technical assistance provided by Westinghouse personnel qualified in the various systems when necessary.
Replacement of individual members was expected to occur during the course of the project, but replacements will be required to possess comparable qualifications.
The Architect Engineer representative was the Lead Advisory Engineer. This position was held by Mr. Ray D. Lombard. He is a graduate Electrical Engineer. He has broad experience in all phases of nuclear plant technology, covering a period of 20 years. He has been involved in the start up of four previous PWR nuclear power plants commencing with the initial start up testing of the Shippingport Nuclear Power Plant.
Technical assistance was provided by DLC Substations and Shop Department, the constructor-engineer (Stone & Webster), the nuclear steam supply system vendor (Westinghouse), plant equipment vendor service representatives and special service contractors (WISCO, NUS and WNES Pre-Service Inspection Group). These groups performed specific tasks such as inspection, calibration, startup checks, monitoring, etc. Such tasks are prerequisite to or in direct assistance or coordination with preoperational testing and plant startup testing. In some cases, they are the individuals responsible for the correction of deficiencies in-plant as determined prior to, during or subsequent to the various tests.

- a. High Head Safety Injection (HPSI) Hot operating Hot operating conditions: The guide allows this to be verified by Flow Test conditions analysis; however, the operability of the check valves must be demonstrated through testing. This can be done by delivering water to the RCS with the charging/SI pumps during hot functional testing by lowering the RCS pressure and observing an increase in pressurizer level and reduction of SI piping temperature. As soon as these conditions are noted and the operation of the check valve verified, the test would be terminated to minimize thermal shock on the system.
- 3. Low Pressure Safety Injection Prior to unit The low head safety injection system is checked to verify design operation flow, flow paths, motor current, speeds and setpoints. Tests are conducted to verify operation from normal and emergency power sources. More specifically that:
- a. Manual and remotely operated valves are operable manually and/or remotely.
- b. Valves installed for redundant flow paths operate as designed.

- a. Low Pressure Safety Injection Ambient conditions a. The LHSI pump performance will be verified while aligned (LPSI) Recirculation Test for recirculation with the exception that suction will be from the RWST. A portion of the flow will be directed to the charging pump suction. Discharge will be to the open RCS.
- b. To avoid delivering sump water to the clean reactor coolant and safety injection systems, the LHSI sump suction path cannot be utilized. However, the simplicity of the sump and suction piping arrangement and the short length of the piping justifies not performing the test. The conservatively calculated total suction line loss, including half blocked screening, is only 8.4 ft. The margin in the available NPSH (calculated minus required) for the worst case of one LHSI pump as single failure is approximately 4.7 ft at the initiation of recirculation flow to the core (see Section 6.3.3.9).
Comparing the line loss with the margin gives further confidence in the ability of each pump to perform without verification testing.

- c. The LHSI and the outside recirculation spray (ORS) pumps (which might be used as a test substitute) and their suction lines are almost entirely buried. It is, therefore, no longer possible to install instrumentation that would adequately demonstrate the validity of the line loss portion of the NPSH calculations over the full line length. The use of sump level, pump discharge pressure and flow rate to establish the line loss would also prove inadequate because the measurement errors will result in an error in measured line loss on the same order of magnitude as the calculated value. Considering that the line loss calculation is quite straightforward, it appears justifiable not to run such a test with either type of pump.
- d. However, the ORS pumps will be tested while taking suction from the sump during other preoperational testing.
Therefore, these pumps will also be used, within the limits of their as-built configuration, to verify the validity of the line loss calculations. A temporary pressure tap will be installed in each ORS pump suction line. This tap will be located between the 12 inch motor-operated gate valve and the penetration of the valve pit wall nearest the pump suction.
The test data can be compared with calculations for the partial suction line. The loss will be that from the circular cap screen, a portion of the suction line and the one valve.
This verification will give further assurance that the LHSI pumps will deliver flow as required during recirculation because of the similarity of the suction paths.

- e. The NPSH calculations assume that there is no problem of vortexing and that the suction lines are unblocked. To assure that these assumptions are valid, and therefore that the sump suction path can be relied upon without a flow test, the following will be done:
(1) Vortex control will be demonstrated by taking suction from the sump using an outside recirculation spray (ORS) pump drawing water through a single suction point (the cross-connected point will be blocked during the test). The flow will be increased to a value above that required by a single LHSI pump, and the sump water level will be lowered below the level it will reach at initiation of recirculation. To maintain a sufficient water level in the sump without flooding the entire containment floor, a temporary dam will be utilized. This dam conforms approximately to the outline of the sump framing inside of the trash bar grating (see Figure 6.4-2 for sump configuration).
Thus the tested pump will take suction through only the circular cap screen. The water will be returned to the dammed sump via temporary piping installed for use in flushing of the recirculation spray system. The suction points of the ORS pumps are similar to those of the LHSI pumps. The temporary dam size and configuration will not support testing beyond the single pump. To do more at this stage of construction would be prohibitive.

(2) Assurance that the LHSI suction lines (from the sump through and including the 12-C42 check valves) are unblocked will be provided by the following:
(a) The lines will be cleaned so that they are free of excessive foreign material, grease, oil and flux.
(b) The 12-C42 check valves will be checked to verify they are installed in the correct direction and that they open properly.
(c) The motor operated sump suction valves (MOV-SI860A&B) will be demonstrated operable. Verification that they open fully will be provided by direct observation.
(d) The remainder of the suction path upstream of the check valves, including the cross connecting U-bend, will be viewed using optical devices.
This will verify that the piping is clear of obstruction.
