Sections 14.1 and 14.2 are historical in nature; they reflect the preoperational and initial
startup test program through the start of commercial operation. Section 14.3 addresses
the postcommercial o perational test program.
14.1 TEST PROGRAM
The preoperational and initial startup program for the Pacific Gas and Electric
Company's (PG&E's) Diablo Canyon Power Plant (DCPP) will demonstrate that:
(1) The plant is ready to operate in a manner that, with reasonable assurance, will not endanger the safety of the public.
(2) The procedures for operating the plant safely have been tested and demonstrated.
(3) The operating organization is kno wledgeable about the plant and the procedures and is fully prepared to operate the plant safely.
The program is designed to demonstrate that structures, components, and systems meet the appropriate design criteria and otherwise operate satisfactorily. The program
includes construction tests, preoperational or functional tests, initial fuel loading, and startup tests. The program will culminate in the operation of the plant at maximum
guaranteed load.
The discussion of tests in this chapter generally excludes construction tests and
otherwise includes only testing associated with safety-related requirements. Testing
excluded from this discussion is administered in a ma nner consistent with the program described in this chapter.
Construction tests include hydrostatic testing, system cleaning, valve leakage tests, control valve operations, electrical continuity checks, electrical performance tests, and
control instrument alignment. Construction tests are usually conducted as the
components and systems are com pleted to ensure readiness for preoperational testing.
Preoperational tests demonstrate, insofar as possible prior to loading nuclear fuel, that
those plant structures, components, and sy stems related to safety have been properly installed and operate according to design req uirements. Preoperational tests that cannot be completed prior to fuel loadin g because the necessary test conditions do not exist will be completed when conditions are suitable for testing.
DCPP UNITS 1 &
2 FSAR UPDATE 14.1-2 Revision 23 December 2016 Preoperational testing of a system begins whenever construction is sufficiently advanced to indicate the test may be compl eted. This phase of testing began in 1973 and has been integrated with other construction activities.
Startup tests demonstrate that the plant wil l perform satisfactorily in normal operation and that, with reasonable assurance, the plant is capable of withstanding the transients
analyzed in this Final Safety Analysis Report (FSAR).
14.1.1 ADMINISTRATIVE PROCEDURES -- TESTING
14.1.1.1 Organizational Responsibilities
The overall responsibility for the preoperation al testing and startup program is assigned to the Lead Startup Engineer.
The Lead Startup Engineer directs other Station Construction Department personnel in preparing and conducting the testing program with technical assistance from the
Engineering Department, Nuclear Plant Operations (NPO), the nuclear steam supply system (NSSS) vendor, and other equipment suppliers as appropriate. The plant
operating organization performs all operations during the testing program. The
Assistant Plant Manager/Plant Superintendent will designate a Startup Coordinator who
will be responsible for startup operational activities.
In some cases there will be procedures, administratively controlled by the NPO Dep artment, which will be included in the Preoperational and Startup Test Program. Their inclusion will occur when they
satisfy the requirements and objectives of a test that would normally be prepared at the direction of the Lead Startup Engineer.
14.1.1.2 Preparation of Procedures
Test procedures are prepared under the direction of the Lead Startup Engineer for all
preoperational and startup tests. Each procedure consists of the test purpose and description, references, prerequisites, initial conditions, instructions (including
acceptance criteria), and data and calculation sheets as required. The status of all
preoperational and startup tests is maintained in a Startup Status Report.
The sources of information for writing the test procedures include approved drawings, specifications, technical literature, system functional de scriptions, similar completed tests from other pressurized water reactor nuclear power plants, manufacturers' testing
recommendations, plant operating procedures, general operating orders and
instructions, and any other design or technical information available.
Test instructions are established using design and technical information and include acceptance criteria established from the functional requirements specified in the appropriate sections of this FSAR or from docu ments approved by the Engineering Department. Space for documenting test results is also included.
DCPP UNITS 1 &
2 FSAR UPDATE 14.1-3 Revision 23 December 2016 14.1.1.3 Reviewing and Approving Procedures
The Lead Startup Engineer is responsible for the preparation of each test procedure
and will request review of tests by the Assistant Plant Manager/Plant Superintendent and others as considered appropriate. The Assistant Plant Manager/Plant
Superintendent is responsible for obtaining comments from NPO. The Lead Startup
Engineer and the Assistant Plant Manager/Plant Superintendent will indicate their
review is complete by signing off the test cover sheet.
The Plant Staff Review Committee (PSRC) will review approved procedures, prior to their conduct, for units with an operating license.
14.1.1.4 Conducting Tests
The Lead Startup Engineer is responsible for conducting all preoperational and startup
tests and assigns the responsibility for conducting individual tests to a Startup Engineer
who, in turn, verifies that all the necessary conditions are established. The Lead
Startup Engineer requests the plant Startup Coordinator to perform the operations step-
by-step, following the sequence specified in the test procedure. During and subsequent
to preoperational testing, power plant operating personn el will operate all switches, breakers, and valves for controlling energized equipment under the direct supervision of
the Shift Foreman in accordance with the startup program, and/or at the request of the
Startup Engineer.
14.1.1.5 Evaluating and Approving Results
The Startup Engineer and the Assistant Plant Manager/Plant Superintendent's representatives make an evaluation of the test results. If the results satisfy the acceptance criteria, they sign off the test as co mpleted. The completed test procedure is reviewed by both the Lead Startup Engineer and the Assistant Plant Manager/Plant
Superintendent and is signed to indicate approval of the completed test.
The results of preoperational tests of safety-related systems will undergo plant staff
review prior to receipt of an operating license. Subsequent to the receipt of an
operating license, the results of all completed preoperational and startup tests will be reviewed by the PSRC.
14.1.1.6 Documentation
Completed procedures and related data and test sheets will be properly identified, indexed, and retained for the plant's perma nent files. The Lead Startup Engineer is responsible for the distribution of all com pleted test procedures. Distribution will be made as individual preoperational and startup test procedures are completed.

DCPP UNITS 1 &
2 FSAR UPDATE 14.1-6 Revision 23 December 2016 14.1.3 TEST OBJECTIVES AND PROCEDURES
14.1.3.1 Preoperational Testing
The testing program p erformed prior to fuel loading ensures that performance of equipment and systems is in accordance wi th design criteria. 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.
As installation of in dividual components and systems is comp leted, each is tested according to approved written pro cedures. The tests are design ed to verify, as nearly as possible, the performance of the components and/or systems un der conditions expected to be experienced during p lant operation. The prerequis ites for these tests include written confirmation that construction activities are complete.
During system tests for which normal plant conditions do not exist and cannot be simulated, the systems are operati onally tested to the maximum extent possible. The remainder of the tests are performed when conditions are suitable for testing. Abnormal plant conditions are simulate d during testing, when required, and when such conditions do not endanger pers onnel or equipment.
Evaluations of test results are made to verify that components and systems are performing satisfactorily and, if not, to provide a basis for recommending corrective action.
Where required, simulated sign als or inputs are used to verify the full operating range of a system and to cali brate and align the system and instruments at these conditions.
Later, systems that are used during normal operat ion are verified and calibrated under actual operating condit ions. Systems that are not used during normal plant operation, but must be in a state of readiness to perform safety-re lated functions, are checked under all modes and test conditions prior to plant startup. Examp les of these systems are the reactor trip system an d engineered safety featur es system logic. Correct operation and setpoi nts are verified during this testing.
Testing performed during preoperational testing will be comp leted before fuel loading. In some cases, it will be necessary to defer certain preoperational tests until after fuel loading. These include tests to be performed on the complete rod control system, rod position indication, and co mplete incore mo vable detector syste
- m. These tests have been identified in Table 14.1-2, Fuel Loading and Initial Startup Testing Summary. Prior to the performance of hot testing following core loa ding, prerequisite col d testing will have been performed. An example of these t ests is the cold rod drop time measurement test. In any event, the surveillance requirements of the Technical Specifi cations will be met as required for each mode transition.
DCPP UNITS 1 &
2 FSAR UPDATE 14.1-7 Revision 23 December 2016 14.1.3.2 Startup Testing
After satisfactory completion of final precritical tests, nucle ar operation of the reactor begins. This final phase of startup and testi ng includes initial criticality, low power testing, and power level escalation.
The purpose of these tests is to establish the operational characteristics of the plant and the core, to acquire data for the determination of setpoints, to establish a dministrative controls d uring reactor operatio ns, and to ensure that operation is within license requirements. A brief d escription of the test program is presented in the following s ections. Table 14.1-2 summarizes th e tests that will be performed from fuel load through plant operation at rate d power, and Figure 14.1-1 shows the sequence in wh ich these tests are performed.
14.1.4 FUEL LOADING AND INITIAL OPERATIONS
14.1.4.1 Fuel Loading
The overall responsibility and direction for initial fuel loading is exercised by PG&E
personnel. Fuel loading begins when al l prerequisite system tests and operations have been satisfactorily completed, an operating license has been obtained from the U. S. Nuclear Regulatory Commission, and a review by the plant staff has determined
that the requirements in the Technical Sp ecifications have been met.
Access to the containment will be controlled by written procedure 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 maint ained to ensure a uniform boron concentration. Boron concentration can be increased via the recirculation system.
The as-loaded core configuration is specified as part of the core design studies conducted well in advance of fuel loading. The core is assembled in the reactor vessel
that is already filled with water containing enough dissolved boric acid to maintain an effective multiplication factor of 0.95, or less, or a boron concentration greater than
2000 ppm. For initial core loading, the 2000 ppm minimum is limiting and results in an effective multiplication factor of less than 0.90. The refueling cavity is partially filled with borated water during initial fuel loading to provide lubrication for the fuel handling
equipment. Coolant chemistry conditions are prescribed in the fuel loading procedure and verified periodically by chemical analysis of moderator samples prior to and during fuel loading operations.
Fuel loading instrumentation shall consist of at least two source range monitors.
Normally, two perman ently installed excore source range neutron channels and three temporary incore source range neutron channels will be available. The permanent channels, when responding, are monitored in the control room by licensed operators.
The temporary channels installed inside the containment structure are monitored by knowledgeable test personnel who, in turn, c ommunicate with the senior licensed DCPP UNITS 1 &
2 FSAR UPDATE 14.1-8 Revision 23 December 2016 operator in charge of fuel loading. At least one channel is equipped with an audible count rate indicator audible in the control room and loading area. Both permanent channels have the capability of displaying the neutron count rate on strip chart
recorders. The temporary channe ls indicate on count rate meters with a minimum of one channel recorded on a strip chart recorder. Minimum count rates attributable to
neutrons generated in the core are required on at least two of the five (i.e., three
temporary and two permanent) available neutron source range channels at all times following installation of the primary sources and the first ten fuel assemblies to continue fuel loading.
Two neutron sources are inserted into the core at locations and sequence specified in the fuel loading program to ensure a neutron population that produces a minimum of
1/2-count/sec for adequate monitoring of the core.
Fuel assemblies, together with inserted com ponents (rod cluster control assemblies
[RCCAs], burnable poison rods, source spider, or thimble plugging devices), are placed in the reactor vessel one at a time according to an approved sequence to provide
reliable core monitoring that minimizes the p ossibility of core mechanical damage. The fuel loading procedure includes a tabular che ck sheet that prescribes the movements of each fuel assembly and its specified inserted compon ents from its initial position in the fuel racks to its final position in the core. Checks are made of component serial numbers and types to guard against possible inadvertent exchanges or substitutions of
components, and two reactor core fuel assem bly tag boards are maintained throughout the core loading operation.
An initial increment of ten fuel assemblies, the first of which contains an active neutron source, is the mi nimum source-fuel increment that permits subsequent meaningful inverse count rate monitoring. This initial i ncrement is determ ined by calculation and previous experience to be markedly subcritical k eff 0.90) under the required conditions of loading.
Each subsequent fuel loading increment is accompanie d by detailed neutron count rate monitoring to determine that the just-loaded increment 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 according to written procedures 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 rate by a factor of two occurs on all operating nuclear channels during any single loading step (excludes anticipated changes due to source/detector geometry)
(2) The neutron count rate on any individual nuclear channel unexpectedly increases by a factor of three during any single loading step (excludes
anticipated changes due to source/detector geometry)
DCPP UNITS 1 &
2 FSAR UPDATE 14.1-9 Revision 23 December 2016 A "high count rate" alarm in the containment and the control room is coupled to the source range channels with a setpoint equal to or less than five times the current count rate. This alarm automatical ly alerts the fuel loading crew to an indication of high count rate and requires an immediate stop of all operations until the situation is evaluated. If it
is immediately determined that no hazards to personnel exist, preselected personnel may remain in the containment to evaluate the cause and determine future action.
Fuel loading procedures specify alignment of fluid systems to prevent inadvertent dilution of the boron concentration in the reactor coolant, restrict the movement of fuel to preclude the possibility of mechanical damage, prescribe the conditions under which loading can proceed, identify chains of respo nsibility and authority, provide for continuous and complete fuel and core component accountability, and establish
procedures to be observed in case of emergency.
14.1.4.2 Postloading Tests
Upon completion of fuel loading, the reactor upper internals and the pressure vessel
head are installed and additional testing is pe rformed prior to initial criticality. The final pressure tests are conducted after filling and venting of the reactor coolant system (RCS) is completed. The purpose of this phase of the program is to prepare the system
for nuclear operation and to establish that design requirements necessary for operation
are achieved.
Mechanical and electrical tests are performed on the RCCA drive mechanisms. A complete operational check of the RCCA dri ve mechanisms and the RCCA position indicator systems is performed. Tests are performed on the reactor trip circuits to verify manual trip operation and actual RCCA drop times are measured for each assembly.
Whenever the RCCA drive mechanisms are being tested, the boron concentration in the RCS is such that criticality cannot be achieved with all RCCAs fully withdrawn. A complete functional electrical and mechanical check is made of the incore nuclear flux mapping system at op erating temperature and pressure.
14.1.4.3 Initial Criticality
Initial criticality is established by sequentiall y withdrawing the shutdown and control groups of control rod assemblies from the core, leaving the last withdrawn control group
inserted far enough in the core to provide effective control when criticality is achieved.
Then the heavily borated reactor coolant is d iluted until criticality is achieved.
Successive stages of control rod assembly group withdrawal and of boron concentration reduction are monitored by observing chang es in neutron count rate. Periodically, samples of the primary coolant boron concentration are obtained and analyzed.
The inverse count rate ratio is used as an indication of the nearness and rate of
approach to criticality of the core during RCCA group withdrawal and during reactor
coolant boron dilution. The rate of approach is reduced as the reactor approaches
extrapolated criticality to ensure that effective control is maintained at all times. Written DCPP UNITS 1 &
2 FSAR UPDATE 14.1-10 Revision 23 December 2016 procedures specify alignment of fluid systems, control the rate at which the approach to criticality may proceed, and predict initial val ues of core conditions under which criticality is expected.
14.1.4.4 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 conservative.
The measurements are made at low power and at or near operating temperature and pressure. The measurements include verifi cation of calculated control rod assembly group reactivity worths, isothermal temperature coefficient under various core
conditions, differential boron concentration reactivity worth, and critical boron
concentrations all as functions of control rod assemb ly group configuration. In addition, measurements of the power distribution are m ade. Concurrent tests are conducted on the instrumentation including the source and intermediate-range nuclear channels.
Written procedures specify the sequence of testing and the conditions under which each
test is to be performed. This ensures 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 while the situation is reviewed by PG&E to determine whether a question of
safety is involved; the deviation is resolved prior to resumption of testing.
14.1.4.5 Power Level Escalation When the operating characteristics of the plant have been verified by low power testing, a program of power level escalation in successive stages brings the unit to its full
licensed power level. Reactor and unit operational characteristics are closely examined
at each power level plateau and the relevance of the safety analysis is verified before
escalation to the next programmed level.
Measurements are made to determine the relative power distribution in the core as
functions of power level.
Secondary system heat balances ensure that the various indications of power level are
consistent and provide a base for calibration of power range neutron channels. The
ability of the reactor control system to respond effectively to signals from reactor plant
and steam plant instrumentation under a variety of conditions encountered in normal operations is verified.
At prescribed power levels, the dynamic response characteristics of the reactor plant
and steam plant are evaluated. The responses of system components are measured for design step and ramp changes in load, 50 percent reduction of load at design rate
and normal recovery, net load rejection, and turbine trip.
DCPP UNITS 1 &
2 FSAR UPDATE 14.1-11 Revision 23 December 2016 Adequacy of radiation shielding is verified by gamma and neutron radiation surveys inside the containment and throughout the plant site at specified power levels. Periodic sampling of reactor coolant is performed to verify the chemical and radiochemical analysis of the reactor plant systems.
The functional performance requirements in some instances are described by specific
quantitative acceptance criteria that are addressed in other sections of the FSAR. In
other cases, acceptance standards may specify that a system or component perform a
given action sequence. In either case, the detailed procedures or the referenced documents used in performing the test include specific acceptance criteria against
which actual performance is measured. Plant conditions for each of the tests are listed in the test procedure.
When completed, this program provides assurance that plant performance is in
accordance with the safety requirements establis hed in the FSAR. The listing of the tests in Tables 14.1-1 and 14.1-2 includes specific identification of the objectives of
each particular test that is required. Figure 14.1-1 gives a graphic presentation of the
chronological sequence of startup testing.
14.1.5 ADMINISTRATIVE PROCED URES -- SYSTEM OPERATION
14.1.5.1 Operating Procedures
Normal and emergency operation of all plant systems and/or major pieces of equipment are carried out in accordance with written procedures prepared by plant personnel and
approved by the Plant Manager or his representative. These procedures are incorporated into the test program by the Lead Startup Engineer as appropriate. Where the prerequisite conditions for an operating procedure cannot be met during the test program, the procedure is demonstrated, under conditions simulating, as nearly as
possible, the prerequisite conditions. The Assistant Plant Manager/Plant
Superintendent reviews each startup test procedure to ensure that the operations
specified in the test procedure are consistent with the normal and emergency operating procedures.
14.1.5.2 Safety Precautions
The measurements and operations during low power escalation testing are similar to normal unit operations at power and normal safety precautions are observed. Those tests that require special operating conditio ns are accomplished using test procedures that prescribe necessary limitations and precautions.

14.2.3.3 Westinghouse
Early in construction, Westinghouse provided a site manager to represent Westinghouse at the site.
DCPP UNITS 1 &
2 FSAR UPDATE 14.2-4 Revision 23 December 2016 The site technical advice that will be provided for startup testing will be dependent upon the test being performed, the level of testing activity at any specific time, and requests by PG&E. Consequently, the personnel l evels, categories, and schedules will be established by the site manager based on anticipated activities during each phase of the startup schedule. Westinghouse representatives will work in conjunction with the DCPP startup organization. A Westinghouse systems engineer will be assigned to the site for hot functional testing and other major systems testing activities. Supporting this
engineer will be several field service engin eers normally assigned on site during plant construction. These engineers will be augmented by specialists from the Westinghouse
home office as required for adequate observation of the specific test being performed.
The specialists will provide specific technical advice for specific tests.
A typical schedule for Westinghouse specialists follows:
(1) RCS Hydrotest - three specialists (a) Reactor Coolant Pump Specialist Scheduled to be on site 2 days pr ior to the hydrotest and for an approximate duration of 1 week or until satisfactory completion of
the activity (b) Chemist Scheduled to be on site 2 days pr ior to the hydrotest and for an approximate duration of 1 week or until satisfactory completion of the activity (c) Quality Assurance of Internals Inspector Scheduled to be on site 2 weeks prior to the hydrotest and for an approximate duration of 2 weeks or until satisfactory completion of

14.2.4 PERSONNEL QUALIFICATIONS
A resume for the Startup Coordinator (Operations Manager) is in the appendix to
Chapter 13.
Qualifications of Westinghouse personnel providi ng technical advice include sufficient personal maturity, work experience, education, and specialized training to satisfy
Westinghouse of their competence to adequately perform tasks assigned by the
Westinghouse site manager. Due to the fluid nature of plant startup schedules, the individuals who will perform these assign ments cannot be identified until specific milestones (i.e., hot functional, etc.) have actually occurred. Timing will be the principal
factor in determining individual availability. Trainees and personnel with limited work experience are not used in positions of significant responsibility. Experience in the
startup of nuclear power plants has indicated that the qualification of Westinghouse
personnel assigned has been fully acceptable.

2 FSAR UPDATE 14.3-1 Revision 23 December 2016 14.3 POSTCOMMERCIAL OPERATIONAL TEST PROGRAM The following regulatory requirement is applicable to the Post-Commercial Operational Test Program:
10 CFR Part 50, Appendix B, Criterion XI - Test Control DCPP is required to establish a test program to ensure that all testing required to demonstrate that structures, systems and components will perform satisfactorily in service is identified and performed in accordance with written test procedures, which incorporate the requirements and acceptance limits contained in applicable design documents. The test program is required to include, as appropriate, proof tests prior to installation, preoperational tests, and operational tests during nuclear power plant operation of structures, systems, and components. Test procedures are required to include provisions for assuring that all prerequisites for the given test have been met, that adequate test instrumentation is available and used, and that the test is performed under suitable environmental conditions.
Test results are required to be documented and evaluated to assure that test requirements have been satisfied.
This section describes the program for testing modifications to DCPP systems per
approved design changes. The program ensures design changes are reviewed for
postmodification operational testing requirements and that all operational tests are
developed and performed prior to returning affected equipment to service.
The engineering director has overall responsibility for postmodification testing.
The scope of a modification is evaluated against plant safety features, industry codes, regulatory requirements, etc. From this evaluation, the scope of required testing is
determined. Temporary test procedures are prepared when existing plant procedures
will not adequately test the modification. Procedures used for performance of
operational testing of design changes are reviewe d and approved by appropriate DCPP management. Operational testing ensures a modification will function in accordance with the design basis by simulating normal and transient conditions when practical.
DCPP defines testing based on work category. Post modification testing (PMT)
consists of maintenance verification testing (MVT), operability verification testing (OVT),
and design verification testing (DVT). Thes e tests may consist of functional tests, dry-run tests, dynamic tests, and inspections. Qualified personnel review and evaluate
the test results for acceptability prior to releasing the equipment for service.
