DESCRIPTION OF THE STARTUP TEST PROGRAM

.1 SCOPE Millstone Unit 2 Startup Test Program consisted of all testing activities commencing at the pletion of the construction phase and ending with the completion and acceptance of all test

. The Startup Test Program was divided into the following test phases.

se I: Initial Inspection and Component Testing se II: Preoperational and Acceptance Testing se III: Pre-Core Hot Functional Testing se IV: Initial Fuel Loading se V: Post-Core Hot Functional Testing se VI: Reactor Initial Criticality se VII: Low Power Physics Testing se VIII: Power Ascension Testing h of the above testing phases will be discussed in detail in succeeding sections. The Initial ection and Component Testing phase began as the various system construction was pleted. This phase was followed by the preoperational, acceptance and pre-core hot ctional test phases.

seismic Category I piping systems designed to ASME Nuclear Classes l and 2 are listed in le 13.12-1.

following discusses the stress analysis techniques used to evaluate the dynamic effects in ng systems. The discussion covers the dynamic effect produced by valve operations and pump s.

ve Operations en dynamic effects are expected in a piping system, excluding the pressurizer safety/relief and tdown cooling piping systems, due to valve operation, the stress analysis is done using imum forces created by valve closures by means of a static analysis with a dynamic loading or of 2 applied for the conservative dynamic loads. For such closed discharging piping ems, supports are installed to take the dynamic transient force from rapid valve closure and/or ef valve opening on each straight leg of piping and to cause the piping to have its fundamental uency in the axial direction above the minimum acceptable natural frequency to make the hod of static analysis valid.

magnitude of the forces created by valve openings in closed piping system is estimated by rmining the change in momentum in each section of straight piping with linear increased e flow rate. For valve closures, a pressure wave is generated in the system which causes a amic response of the system. The maximum magnitude of the pressure wave is calculated m Ap = eV C, where e is fluid density, V is flow velocity change and C is velocity of sound.

stresses caused by these dynamic transient forces are appropriately combined with those sed by seismic, deadweight, and pressure. The total stress is limited to less than those allowed he applicable codes.

pressurizer and shutdown cooling piping systems, which are subject to rapid relief valve nings, are analyzed on a time-history basis. The loading (forcing function) as a result of valve ration is calculated on a time-dependent basis and applied to a dynamic model of the system.

load is applied at specific locations in the system with respect to the time it takes the pressure e to reach that location. It is this time-dependent application of the load which results in the itation of the piping system.

stress evaluation due to the loads developed by rapid relief opening is performed by using the s for Class I piping according to Section III of the ASME BPVC, NB-3650, as modified by e Case 1569. The value of Mi in equations 9 through 14 includes the reaction force moment as sult of relief valve opening.

p Trip stress analysis includes the dynamic effects of pump trips if estimated to be significant.

wever, coastdown time for a centrifugal pump is usually of sufficient duration that water mer effects in the piping systems are normally negligible.

n Steam System analysis of the main steam system included the transient conditions of rapid turbine stop e closure and main steam relief valve lifting. As a result of a turbine stop valve closure, a sure wave is generated within the steam line which causes a dynamic response of the system.

instantaneous stop valve closure is assumed, and the magnitude of t@e pressure wave is ulated from p = e V C.

main steam relief valve system is designed so that blowdown force is transmitted directly to structure and not through the piping by use of mechanical/structural devices. These relief es are provided with discharge stacks to direct the steam flow to atmosphere. The stacks are gned so that back pressure does not cause a valve reaction force.

stresses caused by the dynamic transient forces when combined with those caused by seismic, d weight and pressure are less than 1.2 Sh, which is allowed by ANSI B31.7.

m past experience, flow induced steady state vibration in the main steam line has been shown e insignificant by actual measurements with remote instrumentation. This was verified for lstone 2 by the startup test program.

n Feedwater analysis of the feedwater system has been done to determine any potential for damage due to er hammer. The area of most concern is the pressure waves caused by rapid changes in flow city. The feedwater control valve closure time of 20 seconds or pump coastdown time is much slow to cause water hammer.

the basis of the above discussion, water hammer effects in the feedwater system are negligible.

ssurizer Relief/Safety Valves and Shutdown Cooling Systems se systems are being analyzed by the force-time history approach with respect to relief valve ning. The piping will be sufficiently restrained to carry the imposed loading.

rging Line reciprocating type charging pumps will produce vibratory response in the charging system.

minimize these effects, each charging pump will be provided with a pulsation dampener at the p discharge connection to limit the pressure pulsations to less than 4 percent of the working sure. These dampeners are expected to limit the dynamic effects in the piping system to an eptable level. The startup test program was used to verify the above.

dynamic effects experienced by the letdown, safety injection, containment penetration, boric

, and reactor coolant sampling piping systems are expected to be insignificant. Therefore, the ss analyses for these systems did not include any transient conditions. Verification of the ve assumption will be made by the test program.

eptance Criteria dy state vibration of piping systems, excluding the pressurizer relief/safety and shutdown ling piping systems, was measured in the field. The actual displacements were compared with wable displacements. Allowables are defined as those displacements which produce stresses se amplitudes are less than one-half the endurance limits as defined in ASME Section III. A t-up test program was established to perform the above measurements.

ce the force-time history approach was utilized for the pressurizer relief/safety valve and tdown cooling piping systems, these systems will be excluded from the startup test program.

clusions stress analysis performed for the piping system subjected to dynamic effects is believed quate to insure the integrity of seismic Category I piping systems which are in accordance h ASME Section III, Classes l and 2. A startup test program was established to verify that the lysis and predictions concerning dynamic effects in piping systems are correct.

the systems listed in Table 13.12-1, either the transient effect were proven to be minimal or a program was conducted. A location for measurement of deflection was selected for each em to be tested. The location selected was determined by reviewing the existing analyses and rmining which portion of the system will respond to imposed transient conditions.

instrumentation was located at the specific points defined in Item l above and was monitored ng plant warm-up to indicate that actual pipe movements are following anticipated vements. (This indicated that supports intended to deflect during normal heat-up are free.)

ing imposed plant transients, visual observation of the specific lines was made and the ections observed and recorded.

measured deflections were compared to the calculated deflections and determination made as cceptability.

ive valves are those whose operability is relied upon to perform a safety function such as safe tdown of the reactor or mitigation of the consequences of a postulated pipe break in the reactor lant pressure boundary. These valves are located within the engineered safety features ems, vital support systems, and containment isolation system and are automatically actuated ng a post-incident condition to perform their intended function.

umatically actuated valves without air accumulators are excluded from the above definition of ve valves since the compressed air system is a nonessential system and is not relied upon to ction during post-incident conditions. Pneumatically actuated valves, whether receiving an matic signal or not, are assumed to be operated by spring action to their respective safe ition. Pneumatic actuated valves which are not required to remain operational following a mic disturbance are classified as passive components. A listing of all safety-related umatically actuated valves, including those with air accumulator, is tabulated in the response EC Question 9.32 in Amendment 15.

umatically actuated valves provided with air accumulator are considered active valves even ugh their operation is required during the long term post-incident condition. The air umulator is provided to assure an adequate supply of compressed air for valve operation ng the post-incident case assuming the normal compressed air system is operable. In addition, es with air accumulator that are located in areas which are accessible during LOCI conditions provided with handwheels for manual operation as backup.

air accumulator package consists of tanks, tubing and check valve which are connected to the mal compressed air supply arrangement. The check valve prevents loss of accumulator air owing a postulated loss of the normal compressed air system. The package is completely arate from the valve pneumatic operator except for the air tubing connection to the operator.

accumulator package is designed as a vital system with all components through the check e analyzed for operation during and after a seismic event.

electric motor-operated valves which are required for post-incident operation for vital cesses or for containment isolation are considered active valves. A tabulation of active process or-operated valves is given in the response to AEC Question 4.4 in Amendment 15. The tric motor operators for these valves are all of the Limitorque SMB series and have a history ualification testing to verify their reliability and operability. Extensive testing has been carried by the valve operator manufacturer and by an independent institute. The testing has been done r a number of years, and the most recent testing in the summer of 1972 bears out the rability confirmed initially.

1. MANUFACTURERS TESTS

a. Electric Motor Operator Qualification Testing Shock and Vibration Testing In August, 1970, a Limitorque SMB Series operator was mounted on a test stand having a threaded valve stem driven by the operator simulating

full open position by means of a geared limit switch. The operator had a 4-train geared limit switch installed and all contacts not being used for motor control were wired to electric indicating lights at a remote panel.

The unit successfully completed a 5.3 g shock level at 32 Hz with no discrepancies noted. An exploratory scan of 5 Hz to 35 Hz was made and no critical resonant frequencies were noted on the operator. The unit was shocked and vibrated in each of three different axes a total of 2 minutes on, 1 minute off, 3 times per axis. The unit was operated electrically to both the full-open and full-close position, and all torque switches and limit switches functioned properly. None of the auxiliary limit switches wired to indicating light ever flickered or indicated they were opening or flickering.

All electrical and mechanical devices on the operator worked successfully.

b. Heat Testing In January 1969, a completely assembled and operational SMB series operator was placed in an oven where the temperature was maintained at approximately 325F for a duration of 12 hours1.388889e-4 days <br />0.00333 hours <br />1.984127e-5 weeks <br />4.566e-6 months <br />. The unit was electrically operated every thirty minutes for a period of approximately two minutes per cycle, and the geared limit switches were used to stop the actuator at the full-open and full-closed position of travel. Indicating light circuits were also wired to the geared limit switches.

The test was successful in every respect. There were no malfunctions of the operator and upon inspection of the component parts used, there was no noticeable deterioration or wear.

c. Live Steam Testing In January 1969, a complete SMB series operator was set up for electrical operation, and live steam was piped into he conduit taps on the top of the limit switch compartment. One of the bottom conduit taps was left open to drain off any condensate. The operator was set up on a timer basis for operation over a period of approximately nine hours and operating every thirty minutes for two minutes per cycle. During this test, the live steam in the switch compartment seemed to have no effect whatever on the function of the torque and limit switches in their control of the operator at the full-open and full closed position of travel. In addition, the limit switches were wired up to indicating lights which operated satisfactorily.

The test was successful and there was no noticeable effect on the function of any of the parts in the limit switch compartment.

In January 1969, the operator was mounted on a stand inside a test chamber and a 150 cycle (anticipated equivalent to 40 year life of valve) load test was made on the unit. This test cycle consisted of stroking a 2-3/8 inch diameter valve stem at a speed of 6 inches per minute for a total of approximately 12 inches in two minutes. The valve stem in the full closed position produced a thrust of 16,500 pounds on a rigid plate securely bolted to the test chamber. The unit was wired so that the closing direction and the open position geared limit switch stopped the unit in the full open position.

After the life cycle testing was completed, the unit was inspected and found to be in excellent condition. There was no noticeable wear on any of the parts.

e. Simulated Accident Environment Testing An electric motor operator was tested under conditions which simulated the temperature humidity and chemical environments that could be expected to exist in the containment following some postulated accident such as the rupture of a major reactor coolant pipe.

The operator was placed in an Autoclave type chamber and subjected to 90 psig saturated steam. At specified intervals, the operator was cycled to assure proper operation. Forty minutes after the introduction of steam, a 1.5% boric acid solution was sprayed on the operator assembly. The operator continued to operate satisfactorily. Later, the steam pressure was periodically reduced to simulate post-accident conditions. The boric acid spray was allowed to continue for four hours. The steam pressure was eventually reduced to 15 psig. The test continued for 7 days.

During this time, the operation of the operator became erratic. The corrosive effects of the steam and boric acid spray caused electrical contact malfunctions which were bypassed by the use of an appropriate jumper.

The valve continued to cycle during the seven day period.

A design change was made to the limit switch in order to correct the erratic operation, and it was tested under similar accident conditions and found to operate satisfactorily. This design change has been incorporated into all subsequent applicable models of this operator.

The following testing was conducted:

1. The previous Simulated Accident Environment Test (Item 1-E above) was reconducted with the Limitorque operators exposed to gamma radiation (200 megarads) and increased steam/chemical exposure time from 7 days to 12 days.

2. The previous Live Steam Testing (Item 1-C above) was reconducted in a steam environment as high as 340F during the first day of tests and increased exposure time from 9 hours1.041667e-4 days <br />0.0025 hours <br />1.488095e-5 weeks <br />3.4245e-6 months <br /> to 30 days.

3. The previous shock and Vibration Test (Item 1-A above) was reconducted.

During all of these tests, as appropriate, the operator was periodically cycled and was found to operate satisfactorily.

3. VALVE PURCHASE SPECIFICATION All safety-related valves, including pneumatically actuated valves with and without air accumulators, receive extensive preoperational testing prior to initial fuel loading and periodic surveillance testing after startup. These valves must comply with the purchase specification requirements for testing and seismic analysis.

The purchase specifications for these valves require that they be hydrostatically tested, leak tested and cycled from the extremes of allowed movement of opened or closed.

The valve vendor is also required to submit calculations which show that when the valve assembly is subjected to a 3g inertial load in any direction that stresses incurred are within the code allowable stresses. It is also verified that the first natural frequency is above 20 cps for all valves.

Testing procedures for valves that require operation to meet engineered safety feature requirements were quite extensive during the preoperational testing program. These tests demonstrated proper installation, strength and functional performance of valves. Subsequent to satisfactory preoperational testing, surveillance testing requirements have been established to assure continued satisfactory operation of these valves. A planned surveillance program of valve motor operator testing through the whole operating cycle will be undertaken to prove the operability and setting of the torque and limit switches.

a. System Electrical Tests The purpose of these tests was to verify electrical characteristics of valve operators in performing their function. Preliminary checkout of the operator valve assembly requires that the valve be free to move and that if the motor-operated valve travels in the wrong direction from its midtravel position, its breaker must be tripped immediately, as there would be no torque limit protection. The valve can be operated manually with a handwheel to ascertain its freedom of movement.

The phase rotation of the operator was checked. During valve operation, verification was obtained that the valve travel and motor are stopped by opening the torque limit switch. Similarly, the opening of the valve is terminated by the opening of the limit switch.

In checking the valve for engineered safety feature actuation, the valve was placed in the position opposite to its engineered safety feature position, and then the appropriate signal is simulated. The valve moves to its engineered safety feature position.

Acceptance criteria for these electrical tests are:

1. Valves must open, close, and travel in the proper direction in response to control and engineered safety features signals.

2. The valve open and closed indicating lights must indicate correctly.

3. Valve motor resistance-to-ground reading must be within specification.

4. The specified valve travel time is within specification requirements.

b. System Engineered Safety Features Tests

valves were placed in their nonengineered safety feature position prior to simulating an engineered safety feature signal. Upon initiation of an engineered safety feature signal, the tests for the subject valve demonstrated that the valve travels to its post-incident position.

c. System Functional Testing The purpose of this testing was to verify that the valves perform as intended for normal operation. Cycling the valves under conditions of specified differential pressure and/or flow that may be encountered during plant operation verified that the valve motor did not exceed maximum operating current and cycle time.

d. Integrated Actuation Test The purpose of this test, for which these valves are used to perform, was to demonstrate the full operational sequence that would bring the emergency core cooling systems and the containment cooling systems into action, including the transfer to alternate power sources.

General acceptance criteria for this test are:

1. Upon actuation of the appropriate safety feature, the systems operate as described in the FSAR.

2. Upon loss of normal station power, the safety feature systems continue to perform their designed functions without interruption.

5. THE TECHNICAL SPECIFICATIONS The Technical Specification testing requires that these valves be operated periodically to assure their continued availability and reliability. During the life of the facility, these valves will require maintenance, inspection, repair, and possibly replacement or modification.

ummary, the entire scope of testing verified the valves operability from conditions of extreme ess to normal operation, and the results of the earliest environmental, vibratory, and load ing have been repeatedly verified in later testing by independent research.
